J Am Med Dir Assoc. Timeline[ edit ] Sometime after 4 p. Can Psychiatr Ass J. He entered another classroom and told the three students giving a presentation to "get out," shooting and wounding Maryse Leclair, who was standing on the low platform at the front of the classroom. For instance, Block and colleagues as well as DeLisi and colleagues found no differences in gray matter tissue volume between adolescent cannabis users and matched controls [ 33 , 34 ]. It has been suggested that these receptors increase during adolescence, have a role in genetic expression of neural development, and that alteration of the endocannabinoid system during adolescence may results in a cascade of neurochemical and neurostructural aberrations, thus leading to poorer cognitive and emotional outcomes in adulthood [ 3 , 4 ]. A case series describes five people who were all successfully treated with MPA — mg intramuscularly fortnightly with no side effects reported [ 86 ]. Interestingly, some preliminary evidence supports that marijuana-related toxicity on white matter integrity may be more modest compared to the impact adolescent alcohol use has on the developing brain, although more research in needed in this area. I hate feminists. While white matter findings are subtle in nature, we have observed poorer white matter integrity correlated with poorer neurocognitive functioning in our studies [ 47 ], which underscores the impact that slight alterations in white matter health during this time could have on optimal cognitive functioning. A year-old man who presented with excessive masturbation following a frontal lobe injury showed a marked reduction of symptoms with haloperidol 3 mg [ 66 ]. The media brought an unsuccessful access to information case to compel the police to release the suicide letter. Clin Geriatr Med. Brit J Psychol. J Nerv Ment Dis. Am J Psychol. A more recent case report of a year-old woman residing in a nursing home describes treatment failure with paroxetine, whereas a sharp reduction of aggressive and sexually disinhibited behavior was seen with citalopram 20 mg [ 58 ]. The most common side effects associated with the use of SSRIs are gastro-intestinal problems, headache, and hypersensitivity reactions. Adult studies typically report increased CBF after acute exposure and lower or stabilized CBF after a period of abstinence in heavy users, although this has varied to some degree [ 68 — 70 ]. In order to better understand acute changes with abstinence, we examined neurocognitive performance over 3 weeks of monitored abstinence in marijuana users ages 15— Nickerson and colleagues found that among adolescents ages 14—17, P response i. Medroxyprogesterone MPA does not bind to androgen receptors, but indirectly decreases the level of testosterone by inhibiting the secretion of pituitary luteinizing hormone LH and follicle-stimulating hormone FSH.

However, clinicians often manage problematic behavior with medication because of the ease of administration, perceived efficacy [ 39 ], and lack of trained staff members [ 40 ]. In a similar study by this team of investigators, no differences between cannabis users and community controls were found on measures of executive functioning [ 22 , 23 ]. Longitudinal study of cognition among adolescent marijuana users over three weeks of abstinence. While white matter findings are subtle in nature, we have observed poorer white matter integrity correlated with poorer neurocognitive functioning in our studies [ 47 ], which underscores the impact that slight alterations in white matter health during this time could have on optimal cognitive functioning. Drug Alcohol Rev. While this is not an exhaustive review of the preclinical findings, in general, the data suggest differential and often negative impact on adolescent animals compared to adult animals exposed to THC or other cannabinoid agonists in behavioral, emotional, and social outcomes. Functional changes likely affect the mechanics that underlie structural brain changes, and interactions between these processes cannot be ruled out. Neurocognitive consequences of marihuana--a comparison with pre-drug performance. Brain Inj. In patients with a tendency for exhibitionism or public masturbation, practical solutions such as clothing that opens at the back or lacks zippers have been proposed [ 18 ]. This article has been cited by other articles in PMC. Human and Animal Rights and Informed Consent This article does not contain any studies with human or animal subjects performed by any of the authors. In this perspective, feminist memorializing is considered socially divisive on the basis of gender and therefore harmful by bestowing guilt on all men, irrespective of individual propensity to violence against women. Four brain systems have been implicated in the neurobiology of ISB: the frontal lobes, the temporo-limbic network, the cortico-striatal circuits, and the hypothalamus [ 8 ]. In: Geriatric medicine: an evidence-based approach. Two case reports described a reduction of ISB with rivastigmine treatment up to 3 mg [ 77 , 78 ], although other reports describe the emergence of ISB in patients taking donepezil [ 79 , 80 ]. Similarly, in , amygdala volumes were compared between adolescent cannabis users and non-users. Sexual problems associated with dementia: part 2. Donepezil is available as a generic form which is less expensive than others. Preclinical Studies A fairly large amount of work can be found on animal models of adolescent cannabis exposure. The authors suggest that marijuana may affect neurodevelopment e. Marijuana is the second most widely used intoxicant in adolescence, and teens who engage in heavy marijuana use often show disadvantages in neurocognitive performance, macrostructural and microstructural brain development, and alterations in brain functioning. Classification ISB can include sex talk i. None of the drugs discussed here is licensed for use in ISB, and elderly people, particularly those with dementia, are at high risk of adverse effects. Attention must be paid to the emergence of side effects. The second was a year-old woman with Lewy body dementia, who showed a reduction of ISB after treatment with quetiapine titrated up to 75 mg [ 65 ]. The media brought an unsuccessful access to information case to compel the police to release the suicide letter.

Donepezil is available as a generic form which is less expensive than others. Executive control among adolescent inhalant and cannabis users. A controlled case series comprising 33 patients with behavioral and psychotic symptoms of dementia including, but not restricted to, ISB and 22 matched controls compared usual care to individualized assessment and care delivered by a multidisciplinary team, such as a psychiatric nurse with access to older adults psychiatry and geriatric medicine specialists. Gabapentin and its close relative pregabalin are relatively expensive, valproate salts intermediate in cost depending on formulation , and carbamazepine relatively inexpensive. Spatial functioning in adolescent rats has also shown affected by acute THC treatment [ 83 ]. The authors found higher FA and lower in MD in several tracts in MJ users compared to matched controls; they conclude no evidence of pathological white matter changes despite finding differences between groups [ 33 ]. Comparisons between blood oxygen dependent signal BOLD in adolescent marijuana users and controls in response to cognitive tasks have revealed subtle differences in brain activation patters in marijuana users. No one moved at first, believing it to be a joke until he fired a shot into the ceiling. Results Non-pharmacological treatment Although there are few reports of non-pharmacological interventions and there is a lack of evidence for their efficacy, there is a general agreement that they should be the first-line treatment for ISB in elderly people with dementia [ 20 ], principally because of concerns about safety and ethics [ 38 ]. Findings suggest increased amygdala volume in female users compared to female non-users. Antiandrogens and other drugs with antiandrogenic activity Antiandrogens may reduce androgen levels or inhibit binding at androgen receptors. The compound may illicit premature tissue development, impose a marijuana-related effect on regressive changes e. Sexuality in the nursing home, part 2: managing abnormal behavior-legal and ethical issues. Specific attentional dysfunction in adults following early start of cannabis use. In this perspective, feminist memorializing is considered socially divisive on the basis of gender and therefore harmful by bestowing guilt on all men, irrespective of individual propensity to violence against women. Although all agents carry risks, the overall risks associated with SSRI antidepressants are relatively lower than with other drugs, and these may be a reasonable first choice. His father, a mutual funds salesman, did not consider women to be the equal of men. The authors suggest that marijuana may affect neurodevelopment e. In four males with dementia who had failed to respond to several first-generation antipsychotics and benzodiazepines, a good response was reported for all subjects with trazodone between and mg [ 61 ]. Attention must be paid to the emergence of side effects. IV: disorders of behaviour. J Gerontol. It has been suggested that these receptors increase during adolescence, have a role in genetic expression of neural development, and that alteration of the endocannabinoid system during adolescence may results in a cascade of neurochemical and neurostructural aberrations, thus leading to poorer cognitive and emotional outcomes in adulthood [ 3 , 4 ]. Despite this, sexual expression among older adults is often perceived as non-existent, humorous, grotesque, or even sordid and disgusting [ 2 ]. Lastly, inappropriateness often stems from judgmental mind-sets and arbitrations of the observers clinical staff, family, and other residents , rather than the sexual activities themselves [ 13 ]. Older antipsychotic agents are mostly low in cost, but newer ones may be substantially more expensive. We have not identified any reports of benefits of benzodiazepines in elderly people with ISB. Trends Neurosci. For instance, increased MD in the prefrontal fiber bundles of the corpus callosum in heavy cannabis using adults daily use for more than two years who initiated use during adolescence suggest changes in white matter development associated with cannabis use [ 48 ].

It is important to consider alternative non-pharmacological treatments, as well as discussing issues of ethics and consent with those involved, before initiating treatment. A man aged 76 with alcoholic dementia and ISB was initially responsive to paroxetine, but the response faded. The Ryden Aggression Scale contains a section on sexually aggressive behavior including making obscene gestures, touching body parts of another person, hugging, intercourse, or kissing [ 36 ]. Sex and the nursing home. There have been limited studies evaluating cortical thickness exclusively, however, Lopez-Larson evaluated 18 adolescents ages 16—19 with histories of heavy marijuana use at least marijuana use episodes in the past year compared to non-using controls. Marijuana is the second most widely used intoxicant in adolescence, and teens who engage in heavy marijuana use often show disadvantages in neurocognitive performance, macrostructural and microstructural brain development, and alterations in brain functioning. Marijuana users demonstrated increased cortical thickness in the bilateral lingual, right superior temporal, right parietal and left paracentral regions. Response perseveration and adaptation in heavy marijuana-smoking adolescents. Despite this, sexual expression among older adults is often perceived as non-existent, humorous, grotesque, or even sordid and disgusting [ 2 ]. In one case report of the use of diethylstilbestrol DES in a year-old man who presented with very significant episodes of sexual aggression towards other in-patients, there was a response to DES 1 mg within 3 weeks [ 92 ]. Pharmacological treatments for which there is low-level evidence of efficacy in the literature include antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. Kafka MP, Prentky R. In , an investigation comprising chronic marijuana users and matched controls approximately 19 years old , suggest increased activity in the prefrontal cortex in response to a task requiring executive aspects of attention [ 62 ]. However, as in younger people, not all sexual behavior in older people is inappropriate. Studies show a high density of CB1 cannabinoid receptors in neocortex, hippocampus, amygdala, hypothalamus, basal ganglia, and cerebellum [ 4 ]; therefore the degree to which cannabis use alters cortical and subcortical gray matter tissue development is being increasingly explored in the literature. Ashtari and colleagues found that adolescents with heavy cannabis use enrolled in residential drug treatment had reduced FA and increased MD in cortical association areas such as the temporal-parietal fiber tracts [ 49 ]. Gabapentin and its close relative pregabalin are relatively expensive, valproate salts intermediate in cost depending on formulation , and carbamazepine relatively inexpensive. Discussion Case reports and case series describe successful treatment of ISB with a range of classes of medication, including antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. In the case of an abrupt onset of the ISB, laboratory testing and neuroimaging studies to evaluate for delirium or a new structural lesion should be considered [ 8 ]. Osteoporosis, edema, weight change, and mood changes may occur.

In patients with a tendency for exhibitionism or public masturbation, practical solutions such as clothing that opens at the back or lacks zippers have been proposed [ 18 ]. Kafka MP, Prentky R. Overall, the majority of data support poorer cognitive performance on measures of attention and learning, and memory in adolescent users of cannabis, however frequency and severity of use is likely to play a role, particularly in those reporting younger age of initiation. Functional Imaging fMRI Imaging Changes in cognitive performance after acute and longer-term cannabis use are fairly well documented, even if residual effects are suspected to largely resolve. In that incident, coordination amongst emergency response agencies and prompt intervention were credited with minimizing the loss of life. Findings suggest increased amygdala volume in female users compared to female non-users. Only then should medication be considered. Although there is a lack of published evidence to show that behavioral, supportive, and educational approaches to managing ISB are effective, clinicians may wish to start by considering the place of non-drug management. Results Non-pharmacological treatment Although there are few reports of non-pharmacological interventions and there is a lack of evidence for their efficacy, there is a general agreement that they should be the first-line treatment for ISB in elderly people with dementia [ 20 ], principally because of concerns about safety and ethics [ 38 ]. In females, there may be menopausal symptoms, though this may be less common in post-menopausal women. Focusing on executive functioning, Fontes and colleagues examined chronic cannabis users ages 18— Age of onset also continues to play an important role, as early-onset cannabis users prior to age 16 demonstrated increased activation in the left superior parietal lobe in response to a verbal working memory challenge verbal n-back task , and earlier initiation of use was associated with increased BOLD activity [ 65 ]. Cognition Adult studies of marijuana use often find subtle decreases in performance compared to controls in cognitive domains such as attention, memory, and processing speed; such effects have been discussed as transient in the literature given limited group differences after prolonged abstinence from marijuana [ 5 , 6 ]. In all cases, it is helpful to define target symptoms or behaviors and to provide care staff or caregivers with a simple means of recording these so that the success or otherwise of treatment can be evaluated. Information on the degree of attentional bias to marijuana cues may provide some indication of brain-based differences in cue-reactivity resulting in heavier use of marijuana among certain teenagers. Osteoporosis, edema, weight change, and mood changes may occur. When his weapon failed to fire, he entered the emergency staircase where he was seen reloading his gun. Conjugated estrogen 0. Comparisons between blood oxygen dependent signal BOLD in adolescent marijuana users and controls in response to cognitive tasks have revealed subtle differences in brain activation patters in marijuana users. In elderly patients with dementia, a combination of cognitive deterioration, worsening judgment, and personality changes probably contributes to changes in sexual attitude and behavior. Neurotoxicol Teratol. Similarly, in , amygdala volumes were compared between adolescent cannabis users and non-users. A second study published in found that while age was associated with changes in brain morphometry among non-users, there was no relationship between age and cortical gyrification in adolescent and young adult cannabis users. The adolescent brain. Sex fedio



Changes in male sexuality. Physical manifestations appear to be more frequent in males [ 16 ], whereas women seem more verbal [ 17 ]. Johnson et al. One of the earliest studies on the effects of marijuana on adolescent neurocognitive development evaluated verbal and nonverbal memory performance in cannabis-dependent adolescents ages 14 to 16 compared to matched controls [ 8 ]. Persistent cannabis users show neuropsychological decline from childhood to midlife. Most of the patients involved are likely to be old and often frail so that it is wise to start prescribing at low dose and to increase only very slowly. In , we found marijuana users to have substantially more activation than non-using peers in response to an inhibitory processing task, particularly in parietal and dorsolateral prefrontal cortices, suggesting additional neural resources required to maintain adequate executive control during response inhibition [ 56 ]. Performance of heavy marijuana-smoking adolescents on a laboratory measure of motivation. A pattern of subtle yet potentially detrimental effects in cognitive domains related to attention, learning, and memory are most often described. Cognition Adult studies of marijuana use often find subtle decreases in performance compared to controls in cognitive domains such as attention, memory, and processing speed; such effects have been discussed as transient in the literature given limited group differences after prolonged abstinence from marijuana [ 5 , 6 ]. There is a need for a better understanding of the nature of ISB and better methods of describing and measuring it. In a year-old demented man with aggressive and hypersexual behaviors which had not responded to haloperidol and hydroxyzine, both agitation and hypersexual behavior diminished within 2 weeks of adding pindolol 40 mg to his drug regime [ 98 ].

Neuropsychological functioning in adolescent marijuana users: subtle deficits detectable after a month of abstinence. He entered another classroom and told the three students giving a presentation to "get out," shooting and wounding Maryse Leclair, who was standing on the low platform at the front of the classroom. J Gerontol. Conjugated estrogen 0. Structural NeuroImaging Gray Matter Macrostructure A large body of literature has shown dynamic changes in gray matter structures that are ongoing over adolescent development e. In that incident, coordination amongst emergency response agencies and prompt intervention were credited with minimizing the loss of life. The literature not only suggests neurocognitive disadvantages to using marijuana in the domains of attention and memory that persist beyond abstinence, but suggest possible macrostructural brain alterations e. Serial treatments with MPA up to mg weekly then restored a response: lower doses failed to reduce testosterone levels [ 85 ]. The authors describe decreased activation in response to a bilateral finger-tapping task, and motor function activation was negatively correlated with total lifetime marijuana use [ 64 ]. Kessel B. Gabapentin and its close relative pregabalin are relatively expensive, valproate salts intermediate in cost depending on formulation , and carbamazepine relatively inexpensive. As there is little evidence to suggest that one type of agent is more efficacious than another in this area, it is important to pay particular attention to risks in making a choice of agent. Pharmacologic treatment of hypersexuality and paraphilias in nursing home residents. Discussion Case reports and case series describe successful treatment of ISB with a range of classes of medication, including antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers.

It remains unclear whether such disadvantages reflect pre-existing differences that lead to increased substances use and further changes in brain architecture and behavioral outcomes. In females, there may be menopausal symptoms, though this may be less common in post-menopausal women. Nevertheless, we have seen that differences in brain tissue integrity following heavier marijuana use does predict future risky behaviors such as increased marijuana use and aggressive and delinquent behaviors. It is helpful to identify and monitor target symptoms. It is also unclear what defines acute versus longer-term effects 1 week compared to 6 months, etc. Similarly Gonzalez and colleagues found differences on immediate and delayed recall among young adult cannabis users approximately age 20 compared to nonusing controls, however no differences were observed on measures of impulsivity. In order to better understand acute changes with abstinence, we examined neurocognitive performance over 3 weeks of monitored abstinence in marijuana users ages 15— A year-old man diagnosed with frontotemporal dementia failed to respond to paroxetine. Studies from our laboratory have largely found differences in similar domains following four weeks of monitored abstinence. While this may not represent a typical pathological process, group differences in either direction may still be reflective of a neural alterations. It is important to consider alternative non-pharmacological treatments, as well as discussing issues of ethics and consent with those involved, before initiating treatment. The most common side effects associated with the use of SSRIs are gastro-intestinal problems, headache, and hypersensitivity reactions. Brain Inj. Although all agents carry risks, the overall risks associated with SSRI antidepressants are relatively lower than with other drugs, and these may be a reasonable first choice. A more recent case report of a year-old woman residing in a nursing home describes treatment failure with paroxetine, whereas a sharp reduction of aggressive and sexually disinhibited behavior was seen with citalopram 20 mg [ 58 ]. This suggests differential relationships between marijuana, alcohol, and cognitive outcomes in our sample. Similarly, in , amygdala volumes were compared between adolescent cannabis users and non-users. Lastly, lesions to the right hypothalamus and periventricular area can cause manic symptoms, including increased sexual drive [ 31 ]. In , Harvey and colleagues found adolescent marijuana users age 13—18; use greater than once per week performed worse on tests of attention, learning, and memory; furthermore, poorer performance on executive functioning in this sample was related to more days of cannabis use in the past month [ 13 ]. Psychotropic drugs such as levodopa, benzodiazepines, and alcohol have all been linked with increased agitation and sexual disinhibition [ 33 ]. We have observed similar relationships in magnetic resonance imaging MRI studies examining structural and functional brain alterations [ 18 — 20 ], which will be discussed in greater detail below. Heterogeneity in subcortical brain development: A structural magnetic resonance imaging study of brain maturation from 8 to 30 years. Caution is required as these agents may cause paradoxical reactions with increased agitation in the elderly [ 53 ], and they may worsen cognitive impairment and cause dependence. More adolescent longitudinal studies are still needed to understand both pre-existing differences as compared to discrepancies that develop post-initiation of use.

Longitudinal study of cognition among adolescent marijuana users over three weeks of abstinence. Geriatr Nurs. Four brain systems have been implicated in the neurobiology of ISB: the frontal lobes, the temporo-limbic network, the cortico-striatal circuits, and the hypothalamus [ 8 ]. Sexual disinhibition and dementia. Abstract That article grounds neuroimaging, neurocognitive, and preclinical bars on the websites of cannabis on the unsurpassed brain.

Similar to findings by Lopez-Larson discussed above, the concept of deleterious effects related to early initiation of cannabis has been explored in the neuroimaging literature as well. In a recent investigation by Abush and colleagues , chronic WIN treatment was found to result in both acute and longer term effects not only in spatial memory and object recognition, but interestingly, long term potentiation in areas such as nucleus accumbens pathways [ 84 ]. Am J Psychol. Adv Neurol. Opinion statement Inappropriate sexual behavior ISB is a relatively common and potentially disruptive form of behavior in people with dementia. Drug Alcohol Rev. Caution is advised before using medication in this group of people. Critics of the panel said that the plan failed to provide a workable timeline and strategy for implementation and that with over four hundred recommendations, the final report failed to make an impact. Persistent cannabis users show neuropsychological decline from childhood to midlife. Does cannabis use affect prospective memory in young adults? J Gerontol. Such a marijuana-related effect on white matter and gray matter structures e. The relationship of neuropsychological functioning to measures of substance use in an adolescent drug abusing sample. J Nerv Ment Dis. Antiandrogens and other drugs with antiandrogenic activity Antiandrogens may reduce androgen levels or inhibit binding at androgen receptors. J Geriatr Psychiatry Neurol. He took off his cap, wrapped his coat around his rifle, exclaimed, "Oh shit," and then died by suicide, shooting himself in the head twenty minutes after having begun his attack. Arch Gen Psychiatry. Disruptions in brain development related to neurotoxic effects of regular marijuana use could significantly alter neurodevelopmental trajectories by not only changing neurochemical communication and genetic expression of neural development, but causing a toxic effect on brain tissue. The majority of findings suggest increased recruitment of neural resources possibly reflecting compensation or changes in the efficiency of strategic neural processing in brain areas subserving task-related processing in marijuana using teens. During this period, several women were killed. Sexual incidents in an extended care unit for aged men. Sex fedio



Similar to findings by Lopez-Larson discussed above, the concept of deleterious effects related to early initiation of cannabis has been explored in the neuroimaging literature as well. Ashtari and colleagues found that adolescents with heavy cannabis use enrolled in residential drug treatment had reduced FA and increased MD in cortical association areas such as the temporal-parietal fiber tracts [ 49 ]. Blustein J, Seeman M V. The authors describe decreased activation in response to a bilateral finger-tapping task, and motor function activation was negatively correlated with total lifetime marijuana use [ 64 ]. Int J Neurosci. Such techniques are controversial because of their ethical implications [ 46 ]. J Stud Alcohol Drugs. A detailed analysis of the preclinical studies is beyond the scope of this review, however briefly discussing the existing literature is important for translation to human models. Performance of heavy marijuana-smoking adolescents on a laboratory measure of motivation. Another case report for two patients, aged 72 and 84, who failed to show improvement with thioridazine, describes remission with MPA — mg intramuscularly fortnightly [ 83 ]. One was an year-old man with dementia, parkinsonism, and compulsory masturbation to the point of self-harm; he showed no response to hormonal treatment and paroxetine, but symptoms disappeared after using quetiapine 25 mg after just 2 days, and did not recur in a follow-up period of 2 months, with no side effects reported, nor worsening parkinsonism [ 64 ]. All of these agents can have adverse effects, and none of them emerges as a clear first choice for pharmacological management of ISB. Improper sexual behaviors in elders with dementia living in residential care. Drug Alcohol Depend. A year-old person with vascular dementia treated with citalopram did not respond, whereas mirtazapine up to 30 mg was effective [ 23 ]. Sexuality in the nursing home, part 2: managing abnormal behavior-legal and ethical issues. Short-term memory impairment in cannabis-dependent adolescents. Neural correlates of verbal learning in adolescent alcohol and marijuana users. Most of the patients involved are likely to be old and often frail so that it is wise to start prescribing at low dose and to increase only very slowly. There will need to be a careful balancing of risk and potential benefit. J Gerontol. ISB can be a threat to the mental and physical health of patients and others [ 18 ]; for example, repeated masturbation can cause genital trauma [ 19 ]. An observational study of sexual behavior in demented male patients.





Drug Alcohol Depend. Physical manifestations appear to be more frequent in males [ 16 ], whereas women seem more verbal [ 17 ]. He did not speak to anyone, even when a staff member asked if she could help him. Mapping brain maturation. Age of onset also continues to play an important role, as early-onset cannabis users prior to age 16 demonstrated increased activation in the left superior parietal lobe in response to a verbal working memory challenge verbal n-back task , and earlier initiation of use was associated with increased BOLD activity [ 65 ]. Furthermore, we need to better understand the interactive relationships between alcohol and marijuana use as these substance are commonly used together and may result in differing structural, functional, and cognitive brain changes when used alone or in combination. Similarly, in , amygdala volumes were compared between adolescent cannabis users and non-users. To better understand microstructural differences in tissue integrity among adolescent marijuana users as compared to binge drinkers, we looked at white matter differences between adolescent binge drinkers compared to binge drinkers with histories of heavy marijuana use ages 16— For instance, Block and colleagues as well as DeLisi and colleagues found no differences in gray matter tissue volume between adolescent cannabis users and matched controls [ 33 , 34 ]. Cannabis users did show decreased concavity of the sulci and sulci thinning in frontal, temporal, and parietal lobes compared to non-users, highlighting the potential for cannabis to disrupt normal brain developmental trajectories [ 36 ]. Decreased cortical thickness was reported in the right caudal middle frontal and bilateral superior frontal cortices; decreased thickness was also found in the bilateral insula. Diffusion tensor imaging DTI commonly utilizes two indices of white matter tract coherence to reflect water diffusion in white matter, fractional anisotropy FA and mean diffusivity MD , which are thought to help to identify alterations in the health of white matter fibers. Inappropriate sexual behavior in a geriatric population. Introduction According to the Monitoring the Future Study, marijuana remains the most commonly used illicit drug in adolescence in the United States, one of few increasing in prevalence. The second was a year-old woman with Lewy body dementia, who showed a reduction of ISB after treatment with quetiapine titrated up to 75 mg [ 65 ]. A case series describes five people who were all successfully treated with MPA — mg intramuscularly fortnightly with no side effects reported [ 86 ]. Challenges associated with the definition and assessment of inappropriate sexual behaviour amongst individuals with an acquired neurological impairment. For instance, one lab based paradigm of cue reactivity found increased skin conductivity among teens diagnosed with cannabis use disorder [ 66 ]. We have not identified any reports of benefits of benzodiazepines in elderly people with ISB. He entered another classroom and told the three students giving a presentation to "get out," shooting and wounding Maryse Leclair, who was standing on the low platform at the front of the classroom.







































Comparisons between blood oxygen dependent signal BOLD in adolescent marijuana users and controls in response to cognitive tasks have revealed subtle differences in brain activation patters in marijuana users. Br J Psychiatry. In contrast, Teichner and colleagues found no relationship between marijuana use severity and cognitive performance among cognitively impaired and unimpaired adolescents referred for drug treatment [ 9 ]. Tricyclic antidepressants can have troublesome side effects in older people. Although sexual activity often decreases in elderly people, sexual interest may not [ 1 ]. One subject relapsed, but symptoms were much milder than before [ 82 ]. Cognitive-behavioral therapy CBT for ISB can include re-education of the patient about social norms, encouragement to explore the intentions behind each behavior in order to address cognitive distortions, and negative conditioning techniques; however, this approach can be challenging in people with significant cognitive impairment [ 45 ], and there is a lack of published data. Lastly, inappropriateness often stems from judgmental mind-sets and arbitrations of the observers clinical staff, family, and other residents , rather than the sexual activities themselves [ 13 ]. The neurobiological basis of sexuality is likely founded on complex interactions between different brain systems, neuroendocrine factors, and neurotransmitters. In , DeLisi and colleagues published one of the earlier studies to explore the potential for deleterious effects of cannabis on developing white matter.. Psychosocial issues often contribute to the onset of ISB in predisposed demented patients; these factors include mood instability, premorbid patterns of sexual activity and interest, lack of habitual sexual partner or misidentification of someone else as usual partner, lack of privacy, understimulating or unfamiliar environment, misinterpretation of cues, and potentially many others [ 33 ]. Anxiolytic agents Tiller et al. Paroxetine 20 mg was used with beneficial effect within 1 week and no substantial side effects in a year-old man with ISB and alcoholic dementia, who had not responded to haloperidol, chlorpromazine, lorazepam, lithium, and nortriptyline [ 57 ]. Changes in male sexuality. Cyproterone acetate CPA inhibits the interaction between endogenous androgens and androgen receptors, as well as reducing the biosynthesis of androgens. In recent work, Tait and colleagues looked at young adult cannabis users ages 20—24 and found memory deficits, however cessation of cannabis use was associated with improved performance with abstinence over the course of eight years [ 21 ]. Sexual behavioral changes in Alzheimer disease. Another case report for two patients, aged 72 and 84, who failed to show improvement with thioridazine, describes remission with MPA — mg intramuscularly fortnightly [ 83 ]. These activities can cause anxiety, distress, and embarrassment in caregivers, often disrupting the continuity of care at home and leading to confinement at home or institutionalization [ 20 ]. The majority of findings suggest increased recruitment of neural resources possibly reflecting compensation or changes in the efficiency of strategic neural processing in brain areas subserving task-related processing in marijuana using teens. Neural correlates of verbal learning in adolescent alcohol and marijuana users. A case is reported of a year-old patient with dementia who failed to respond to thioridazine, but responded to transdermal estrogen within 1 week, which allowed tapering of the antipsychotic [ 94 ]. We did not observe group differences in neurovascular functioning after four weeks of abstinence, suggesting marijuana may influence cerebral blood flow acutely with a possible return to baseline with prolonged abstinence [ 71 ]. In a similar study by this team of investigators, no differences between cannabis users and community controls were found on measures of executive functioning [ 22 , 23 ]. At least two students left notes confirming that they had committed suicide due to distress caused by the massacre.

He was physically and verbally abusive to his wife and son, discouraging tenderness between mother and child. No one moved at first, believing it to be a joke until he fired a shot into the ceiling. While this is not an exhaustive review of the preclinical findings, in general, the data suggest differential and often negative impact on adolescent animals compared to adult animals exposed to THC or other cannabinoid agonists in behavioral, emotional, and social outcomes. J Am Geriatr Soc. Does cannabis use affect prospective memory in young adults? It has been suggested that these receptors increase during adolescence, have a role in genetic expression of neural development, and that alteration of the endocannabinoid system during adolescence may results in a cascade of neurochemical and neurostructural aberrations, thus leading to poorer cognitive and emotional outcomes in adulthood [ 3 , 4 ]. Effective treatment of ISB with CPA 50 mg was reported in a year-old man with AIDS-related dementia [ 87 ]; however, another case report described unsuccessful CPA treatment in a year-old with dementia, with additional numerous adverse effects impacting on mobility [ 88 ]. The literature has shown linear increases in white matter over early development. Jacobsen and colleagues were the first to pilot an auditory working memory n-back fMRI study comparing marijuana users with tobacco use compared to a tobacco using group and control group. Classification ISB can include sex talk i. Prevalence of neuropsychiatric symptoms in dementia and mild cognitive impairment: results from the cardiovascular health study. Findings suggest increased amygdala volume in female users compared to female non-users. In response to a third task assessing verbal encoding, marijuana users demonstrated increased encoding-related activation in anterior brain regions as compared to decreased activation in posterior regions, despite no differences in task performance [ 20 ]; findings may suggest increased recruitment of neural resources in brain areas subserving task-related processing in marijuana using teens. Pharmacological treatments for which there is low-level evidence of efficacy in the literature include antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. Finally, sexualized conducts may cause a conflict between ethical and legal responsibilities of clinicians, since hindering sexual expression can be seen as a violation of the principle of autonomy [ 18 ]; therefore, the capacity to consent needs to be assessed [ 21 ]. Neural correlates of verbal learning in adolescent alcohol and marijuana users. There are two case reports of the use of quetiapine for treating ISB. A case series describes five people who were all successfully treated with MPA — mg intramuscularly fortnightly with no side effects reported [ 86 ]. Int Psychogeriatr. There is a risk of postural hypotension, which can lead to falls, and anticholinergic effects including constipation, dry mouth, and urinary retention. They can cause coldness, fatigue, and sleep disturbance. Recently, in a small sample of adolescents approximately 18 years of age, WM alterations were found in cannabis users compared to controls. Structural NeuroImaging Gray Matter Macrostructure A large body of literature has shown dynamic changes in gray matter structures that are ongoing over adolescent development e. Am J Psychol. He changed the magazine in his weapon and moved to the front of the class, shooting in all directions. Drug Alcohol Depend. One of the earliest studies on the effects of marijuana on adolescent neurocognitive development evaluated verbal and nonverbal memory performance in cannabis-dependent adolescents ages 14 to 16 compared to matched controls [ 8 ]. In: Geriatric medicine: an evidence-based approach. Disruptions in brain development related to neurotoxic effects of regular marijuana use could significantly alter neurodevelopmental trajectories by not only changing neurochemical communication and genetic expression of neural development, but causing a toxic effect on brain tissue. Corresponding author.



Sexual behavioral changes in Alzheimer disease. A detailed analysis of the preclinical studies is beyond the scope of this review, however briefly discussing the existing literature is important for translation to human models. Critics of the panel said that the plan failed to provide a workable timeline and strategy for implementation and that with over four hundred recommendations, the final report failed to make an impact. An observational study of sexual behavior in demented male patients. Blood Perfusion The neurovascular effect of marijuana use in adolescence has not been studied extensively. Preclinical Studies A fairly large amount of work can be found on animal models of adolescent cannabis exposure. Findings also included higher cerebral blood flow in males reporting early initiation of marijuana use [ 44 ]. Age of onset also continues to play an important role, as early-onset cannabis users prior to age 16 demonstrated increased activation in the left superior parietal lobe in response to a verbal working memory challenge verbal n-back task , and earlier initiation of use was associated with increased BOLD activity [ 65 ]. Interestingly, some preliminary evidence supports that marijuana-related toxicity on white matter integrity may be more modest compared to the impact adolescent alcohol use has on the developing brain, although more research in needed in this area. Involvement of staff, families, and caregivers in discussion will be important. Anticonvulsants can have a wide range of side effects including sedation, gastro-intestinal problems, risk of falls, hypo- or hypertension, and endocrine changes. Neuropsychological functioning in adolescent marijuana users: subtle deficits detectable after a month of abstinence. White Matter Microstructure White matter tissue integrity e.





Marijuana use in adolescence could have implications for academic functioning, as well as social and occupational functioning extending into later life. Studies show a high density of CB1 cannabinoid receptors in neocortex, hippocampus, amygdala, hypothalamus, basal ganglia, and cerebellum [ 4 ]; therefore the degree to which cannabis use alters cortical and subcortical gray matter tissue development is being increasingly explored in the literature. Reported results are inconsistent. Decreased FA in cortical and subcortical areas e. Resting state activity was also altered, as THC increased baseline activity [ 72 ]. Notably, those individuals with weekly use before age 18 demonstrated greater decline in cognitive performance [ 27 ]. In our laboratory, we have found white matter alterations in our abstinent teen marijuana users ages 16—19 compared to controls. Similarly Gonzalez and colleagues found differences on immediate and delayed recall among young adult cannabis users approximately age 20 compared to nonusing controls, however no differences were observed on measures of impulsivity. Firstly, the concept of appropriateness varies among individuals and can be affected by numerous elements, such as religious beliefs or prevailing societal views of elderly persons [ 12 ]. Psychotropic drugs such as levodopa, benzodiazepines, and alcohol have all been linked with increased agitation and sexual disinhibition [ 33 ]. This article has been cited by other articles in PMC. Executive control among adolescent inhalant and cannabis users. All of these agents can have adverse effects, and none of them emerges as a clear first choice for pharmacological management of ISB. Ann N Y Acad Sci. The same effect was not found in the tobacco-only control group suggesting marijuana use may lead to developmental changes masked by nicotine use [ 54 , 55 ] We have conducted several BOLD fMRI studies evaluating differences in activation patters between our sample of abstinent marijuana users and matched controls. While white matter findings are subtle in nature, we have observed poorer white matter integrity correlated with poorer neurocognitive functioning in our studies [ 47 ], which underscores the impact that slight alterations in white matter health during this time could have on optimal cognitive functioning.





Between-group differences in attention, learning, and memory were identified at baseline, however while learning and memory performance reached similar levels of performance to controls after 3 weeks of abstinence, attention differences persisted [ 16 ]. A more recent case report of a year-old woman residing in a nursing home describes treatment failure with paroxetine, whereas a sharp reduction of aggressive and sexually disinhibited behavior was seen with citalopram 20 mg [ 58 ]. Nickerson and colleagues found that among adolescents ages 14—17, P response i. Challenges associated with the definition and assessment of inappropriate sexual behaviour amongst individuals with an acquired neurological impairment. Interestingly, some preliminary evidence supports that marijuana-related toxicity on white matter integrity may be more modest compared to the impact adolescent alcohol use has on the developing brain, although more research in needed in this area. Brain tumors presenting as functional psychiatric disturbances. None of the agents discussed here is licensed for use in ISB, and so the physician must carefully consider their use and advise patients and caregivers of risks and benefits. Similarly, there is emerging evidence on genetic vulnerability to cannabis, and more information on consumed cannabis is needed as studies move sole focus from THC to other cannabinoids e. Performance of young adult cannabis users on neurocognitive measures of impulsive behavior and their relationship to symptoms of cannabis use disorders. The crowd scattered after he shot a woman standing near the kitchens and wounded another student. Aims This study systematically reviews the published literature on the current treatment options for ISB in older adults with dementia in order to support the clinician in managing ISB. Finally, sexualized conducts may cause a conflict between ethical and legal responsibilities of clinicians, since hindering sexual expression can be seen as a violation of the principle of autonomy [ 18 ]; therefore, the capacity to consent needs to be assessed [ 21 ]. One subject relapsed, but symptoms were much milder than before [ 82 ]. Nevertheless, in some situations, medication may provide a useful part of a management plan for ISB. Such a marijuana-related effect on white matter and gray matter structures e.

Szasz G. Despite no group differences on impulsivity, the authors found that worse performance on a decision making task was related to more cannabis use disorder symptoms [ 24 ]. Three case reports describe reduced ISB in people with dementia treated with gabapentin [ 69 — 71 ]. Gonadotropin-releasing hormone analogs Gonadotropin-releasing hormone analogs GnRHA suppress testosterone production by stimulating the secretion of pituitary LH and FSH, with subsequent increase in estrogen levels and decrease of testosterone. In a few-old demented man with skilled and hypersexual needs which had not sex fedio to haloperidol and hydroxyzine, both elevated and hypersexual close diminished within 2 properties of approaching pindolol 40 mg to his personality regime [ 98 ].

Lastly, lesions to the right hypothalamus and periventricular area can cause manic symptoms, including increased sexual drive [ 31 ]. One of the earliest studies on the effects of marijuana on adolescent neurocognitive development evaluated verbal and nonverbal memory performance in cannabis-dependent adolescents ages 14 to 16 compared to matched controls [ 8 ]. Caution is advised before using medication in this group of people. Antipsychotics and hormonal agents may have very significant side effects and should be used with caution. While between group differences persisted between marijuana users and controls, surprisingly, teens engaging in binge drinking only looked significantly worse on indices of white matter integrity i. We present the evidence divided into non-pharmacological and pharmacological treatments. It is important to consider alternative non-pharmacological treatments, as well as discussing issues of ethics and consent with those involved, before initiating treatment. ISB should be seen as a part of the symptom cluster of behavioral and psychiatric disturbances associated with dementia, which is disruptive and distressing, and impairs the care of the patient [ 8 ]. We have observed similar relationships in magnetic resonance imaging MRI studies examining structural and functional brain alterations [ 18 — 20 ], which will be discussed in greater detail below. Neuropsychological functioning in adolescent marijuana users: subtle deficits detectable after a month of abstinence. The compound may illicit premature tissue development, impose a marijuana-related effect on regressive changes e. Although all agents carry risks, the overall risks associated with SSRI antidepressants are relatively lower than with other drugs, and these may be a reasonable first choice. In recent work, Tait and colleagues looked at young adult cannabis users ages 20—24 and found memory deficits, however cessation of cannabis use was associated with improved performance with abstinence over the course of eight years [ 21 ]. Findings suggest increased amygdala volume in female users compared to female non-users. A prospective study conducted in examined neurocognitive performance among 17—21 year olds with history of soft drug exposure in utero compared to prior performance at 9—12 years old. Future work should focus on prospective investigations to help disentangle dose-dependent effects from pre-existing effects, and to better understand the interactive relationships with other commonly abused substances e. Int J Neurosci. Atypical antipsychotics can produce weight gain and a metabolic syndrome. For instance, increased MD in the prefrontal fiber bundles of the corpus callosum in heavy cannabis using adults daily use for more than two years who initiated use during adolescence suggest changes in white matter development associated with cannabis use [ 48 ]. Psychotropic drugs such as levodopa, benzodiazepines, and alcohol have all been linked with increased agitation and sexual disinhibition [ 33 ]. Changes in male sexuality.



Studies from our laboratory have largely found differences in similar domains following four weeks of monitored abstinence. Antipsychotics and hormonal agents may have very significant side effects and should be used with caution. We did not observe group differences in neurovascular functioning after four weeks of abstinence, suggesting marijuana may influence cerebral blood flow acutely with a possible return to baseline with prolonged abstinence [ 71 ]. The majority of findings suggest increased recruitment of neural resources possibly reflecting compensation or changes in the efficiency of strategic neural processing in brain areas subserving task-related processing in marijuana using teens. Bardell et al. Mulligan T, Siddiqi W. White matter integrity in several of these regions was linked to neurocognitive performance on measures of attention, working memory, and processing speed; we have also seen white matter linked to emotional functioning and prospective risk taking in our substance users [ 52 , 53 ]. It is important to rule out treatable causes of ISB such as pain, boredom, lack of stimulation, and lack of an outlet for affectional needs. Ashtari and colleagues found that adolescents with heavy cannabis use enrolled in residential drug treatment had reduced FA and increased MD in cortical association areas such as the temporal-parietal fiber tracts [ 49 ]. These activities can cause anxiety, distress, and embarrassment in caregivers, often disrupting the continuity of care at home and leading to confinement at home or institutionalization [ 20 ]. Studies are actively evaluating emotional functioning and neurochemical transmission in adolescent animals after exposure to cannabinoid agonists, as well as how cannabinoids moderate state-dependent learning based on brain regions [ 85 , 86 ]. White matter integrity in adolescents with histories of marijuana use and binge drinking.





He had told the clerk that he was going to use it to hunt small game. Jacobsen and colleagues were the first to pilot an auditory working memory n-back fMRI study comparing marijuana users with tobacco use compared to a tobacco using group and control group. For example, Ehrenreich and colleagues found that initiation of marijuana use prior to age 16 predicted impaired reaction time on a task of sustained attentional processing [ 28 ]. We looked for original articles, namely case reports, case series, case-control and cohort studies, and randomized controlled trials; however, we also considered previous reviews and expert opinions published where evidence-based studies were lacking. Many older people are prescribed many agents simultaneously, and so the possibility of drug interactions must be considered in each case. In this perspective, feminist memorializing is considered socially divisive on the basis of gender and therefore harmful by bestowing guilt on all men, irrespective of individual propensity to violence against women. J Gerontol. Side effects of antipsychotics can be very significant. A case series of ten people with dementia and ten age- and sex-matched controls showed that consistent redirection and enhanced communication through an interpreter was associated with a reduction of ISB [ 23 ]. Valproate salts have not proved useful in controlling agitation in dementia [ 75 ], and currently, there is no evidence that they might work in ISB. More adolescent longitudinal studies are still needed to understand both pre-existing differences as compared to discrepancies that develop post-initiation of use. The present paper reviews published data on pharmacological interventions for ISB, but is not intended to provide a complete review of a field where it is essential to ensure that there is a full assessment of the problem, careful attention to ethics and consent, and careful monitoring of response. In one case report, two elderly people with dementia and ISB responded to clomipramine — mg after no response to thioridazine; however, one of these patients had been initially prescribed mg of clomipramine which had to be stopped and re-titrated due to postural hypotension [ 60 ]. Am J Dis Child. Group differences in our studies generally persist despite controlling for alcohol use present in both controls and marijuana users; but to further understand differential contributions of marijuana and alcohol to neurocognitive functioning in our sample, we examined unique associations between alcohol use severity and cognitive functioning in both marijuana users as well as controls. In , Harvey and colleagues found adolescent marijuana users age 13—18; use greater than once per week performed worse on tests of attention, learning, and memory; furthermore, poorer performance on executive functioning in this sample was related to more days of cannabis use in the past month [ 13 ]. The media brought an unsuccessful access to information case to compel the police to release the suicide letter. Three case reports describe reduced ISB in people with dementia treated with gabapentin [ 69 — 71 ]. In regard to higher-order cognitive functioning, Lane and colleagues found adolescents ages 14—18 with histories of heavy marijuana use performed worse on perseverative responding and flexible thinking compared to controls with limited histories of use. They can cause coldness, fatigue, and sleep disturbance. This suggests differential relationships between marijuana, alcohol, and cognitive outcomes in our sample. Quantitative analysis of interictal behavior in temporal lobe epilepsy. Neural correlates of verbal learning in adolescent alcohol and marijuana users.







































Etiology Many neurobiological and psychosocial factors can contribute to the onset and maintenance of ISB. This same research group also found evidence of reduced motivation among marijuana users compared to controls [ 11 , 12 ]. Aetiology, assessment and treatment. In , Pope and colleagues also found that early-onset or initiation prior to age 17 was related to poorer performance on verbal memory and fluency tasks, as well as verbal IQ [ 29 ]. Mechanism of disinhibition after brain lesions. In this perspective, feminist memorializing is considered socially divisive on the basis of gender and therefore harmful by bestowing guilt on all men, irrespective of individual propensity to violence against women. Sexuality in the nursing home, part 1: attitudes and barriers to sexual expression. In a year-old demented man with aggressive and hypersexual behaviors which had not responded to haloperidol and hydroxyzine, both agitation and hypersexual behavior diminished within 2 weeks of adding pindolol 40 mg to his drug regime [ 98 ]. Spatial functioning in adolescent rats has also shown affected by acute THC treatment [ 83 ]. Lastly, inappropriateness often stems from judgmental mind-sets and arbitrations of the observers clinical staff, family, and other residents , rather than the sexual activities themselves [ 13 ]. Alterations of cortical thickness were related to severity of cannabis use and younger age of initiation of use in several brain regions.

The authors found cannabis users performed the task less accurately and failed to deactivate the right hippocampus across conditions. There are no randomized controlled trials. The authors found that adolescent cannabis users reporting initiation prior to age 15 demonstrated poorer performance on tasks of sustained attention, impulse control, and executive functioning [ 30 ]. Int J Neurosci. Resting state activity was also altered, as THC increased baseline activity [ 72 ]. Attention must be paid to the emergence of side effects. Pharmacological treatments for which there is evidence of efficacy in literature include antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. Earlier initiation of marijuana use e. Group differences in our studies generally persist despite controlling for alcohol use present in both controls and marijuana users; but to further understand differential contributions of marijuana and alcohol to neurocognitive functioning in our sample, we examined unique associations between alcohol use severity and cognitive functioning in both marijuana users as well as controls. In both the adult and adolescent literature abstinence periods and study designs vary widely abstinence may vary from hours to years , and therefore making direct comparisons continues to be a challenge and the chronicity of cognitive alterations remains unclear. Four brain systems have been implicated in the neurobiology of ISB: the frontal lobes, the temporo-limbic network, the cortico-striatal circuits, and the hypothalamus [ 8 ]. They can cause coldness, fatigue, and sleep disturbance. Prescott and colleagues found decreases in metabolite concentrations e. Age of onset also continues to play an important role, as early-onset cannabis users prior to age 16 demonstrated increased activation in the left superior parietal lobe in response to a verbal working memory challenge verbal n-back task , and earlier initiation of use was associated with increased BOLD activity [ 65 ]. An observational study of sexual behavior in demented male patients. Medina and colleagues and found no difference in hippocampal volumes or prefrontal cortex volume in adolescent cannabis users compared to matched controls, despite observed differences in both hippocampus and prefrontal cortex in adolescent alcohol users compared to matched controls [ 19 , 38 ]. One of the earliest studies on the effects of marijuana on adolescent neurocognitive development evaluated verbal and nonverbal memory performance in cannabis-dependent adolescents ages 14 to 16 compared to matched controls [ 8 ]. Our first prospective investigation found that cumulative marijuana use over the course of eight years teens followed from ages 13—30 was related to poorer performance on measures of attentional functioning [ 14 ]. Sedation and impairment of cognitive function is common. There have been considerable additions to the literature over the last decade, yet the degree of impairment related to marijuana use in adolescence remains inconclusive. Sexuality in the older person. Several case reports describe combinations of drugs to treat these symptoms [ 99 ], but clinicians should be cautious with polypharmacy in the elderly, especially when it involves carbamazepine or cimetidine, as these drugs have important effects on hepatic metabolism and pharmacological interactions [ 42 ], and elderly people are particularly vulnerable to adverse effects of medication.



Hypersexuality in stroke. Cannabis use and cognitive function: 8-year trajectory in a young adult cohort. Cholinesterase inhibitors Cholinesterase inhibitors may affect sexual function in many ways, including altering testosterone levels, but the exact processes involved are still uncertain [ 76 ]. White Matter Microstructure White matter tissue integrity e. Only then will it be possible to carry out well-designed, double-blind randomized controlled trials in order to evaluate the effectiveness, safety, and tolerability of the treatments of ISB. Arch Phys Med Rehabil. In addition to non-pharmacological approaches to management, a wide range of classes of medication has been used in ISB, and the results have been reported as single cases or short series, though none has been the subject of a randomized clinical trial, in part because of the lack of a well-defined method of observing and measuring ISB, as well as the significant ethical considerations. We have not identified any reports of benefits of benzodiazepines in elderly people with ISB. Several recent studies outside of our laboratory have shown similar findings. Decreased FA in cortical and subcortical areas e. Adv Neurol. He did not speak to anyone, even when a staff member asked if she could help him. Two case reports described a reduction of ISB with rivastigmine treatment up to 3 mg [ 77 , 78 ], although other reports describe the emergence of ISB in patients taking donepezil [ 79 , 80 ]. A study evaluating young adults age range 21—27 found that acute THC administration increased blood perfusion in areas important for emotional and cognitive processing, such as the anterior cingulate, frontal cortex, and insula, and reduced perfusion in posterior brain regions. While this may not represent a typical pathological process, group differences in either direction may still be reflective of a neural alterations. Deficits in object recognition have also been reported in male and female pubertal rats treated with a cannabinoid receptor agonist as well as THC [ 80 — 82 ], and there is some support that findings are consistent across age groups. Between-group differences in attention, learning, and memory were identified at baseline, however while learning and memory performance reached similar levels of performance to controls after 3 weeks of abstinence, attention differences persisted [ 16 ]. One of the first research groups to look at cannabinoid exposure found poorer performance on cognitive tasks, such as maze learning, in immature rats compared to mature rats treated with THC [ 76 ]. The relationship of neuropsychological functioning to measures of substance use in an adolescent drug abusing sample. IV: disorders of behaviour. Medroxyprogesterone MPA does not bind to androgen receptors, but indirectly decreases the level of testosterone by inhibiting the secretion of pituitary luteinizing hormone LH and follicle-stimulating hormone FSH. Pharmacological treatment Despite pharmacological treatments being more frequently used than non-pharmacological approaches [ 51 ], there are no randomized controlled trials for any of the drugs commonly prescribed, with all current evidence emerging from case series and case reports. One subject relapsed, but symptoms were much milder than before [ 82 ]. Heterogeneity in subcortical brain development: A structural magnetic resonance imaging study of brain maturation from 8 to 30 years. The adolescent brain.





Drug Alcohol Depend. He fired on students in the front row and then killed two women who were trying to escape the room, while other students dove under their desks. Marijuana is the second most widely used intoxicant in adolescence, and teens who engage in heavy marijuana use often show disadvantages in neurocognitive performance, macrostructural and microstructural brain development, and alterations in brain functioning. Verbal learning and memory in adolescent cannabis users, alcohol users and non-users. Gabapentin is known to cause reduced libido, anorgasmia, and erectile dysfunction [ 42 ]. Attention must be paid to the emergence of side effects. You're all a bunch of feminists. Resting state activity was also altered, as THC increased baseline activity [ 72 ]. There is a low but definite risk of serotonin syndrome if prescribed in combination with other serotonergic agents. Most are inexpensive agents. To better understand microstructural differences in tissue integrity among adolescent marijuana users as compared to binge drinkers, we looked at white matter differences between adolescent binge drinkers compared to binge drinkers with histories of heavy marijuana use ages 16— A case series describes five people who were all successfully treated with MPA — mg intramuscularly fortnightly with no side effects reported [ 86 ]. The neurobiological basis of sexuality is likely founded on complex interactions between different brain systems, neuroendocrine factors, and neurotransmitters. There is a need for a better understanding of the nature of ISB and better methods of describing and measuring it. Cannabis and the brain. Stiles J, Jernigan TL. Caution is advised before using medication in this group of people. Of these, 14 responded to either cimetidine — mg, spironolactone 75 mg, or ketoconazole, or to all three drugs combined together [ 91 ]. Notably, former heavy users reporting 3 months without regular use had similar scores to non-marijuana using controls [ 10 ]. Rubino T, Parolaro D. In this perspective, feminist memorializing is considered socially divisive on the basis of gender and therefore harmful by bestowing guilt on all men, irrespective of individual propensity to violence against women. These remodeling processes are purportedly linked to efficient neural processing, and believed to underlie specialized cognitive processing necessary for optimal neurocognitive performance. Blustein J, Seeman M V. Several recent studies outside of our laboratory have shown similar findings. For instance, Block and colleagues as well as DeLisi and colleagues found no differences in gray matter tissue volume between adolescent cannabis users and matched controls [ 33 , 34 ].





Iversen L. Beta-blockers slow the heart rate and are contraindicated in patients with heart block and asthma. Furthermore, we need to better understand the interactive relationships between alcohol and marijuana use as these substance are commonly used together and may result in differing structural, functional, and cognitive brain changes when used alone or in combination. Attention must be paid to the emergence of side effects. Performance of young adult cannabis users on neurocognitive measures of impulsive behavior and their relationship to symptoms of cannabis use disorders. Structural NeuroImaging Gray Matter Macrostructure A large body of literature has shown dynamic changes in gray matter structures that are ongoing over adolescent development e. It is helpful to identify and monitor target symptoms. Discussion Case reports and case series describe successful treatment of ISB with a range of classes of medication, including antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. Although sexual activity often decreases in elderly people, sexual interest may not [ 1 ]. Carbamazepine has been associated with lower testosterone levels in young women with epilepsy [ 72 ]. Anticonvulsants Anticonvulsants have been trialed for the treatment of ISB in dementia; however, the underlying mechanism by which they affect sexual function is still poorly understood [ 68 ]. Cannabis users did show decreased concavity of the sulci and sulci thinning in frontal, temporal, and parietal lobes compared to non-users, highlighting the potential for cannabis to disrupt normal brain developmental trajectories [ 36 ]. The panel proposed a two-pronged "National Action Plan" consisting of an "Equality Action Plan" and a "Zero Tolerance Policy" designed to increase women's equality and reduce violence against women through government policy. Schneider and Koch , have reported alterations in pubertal rats treated with the receptor agonist WIN, discrepancies in performance range from sensorimotor functioning, object recognition memory, and social behavior [ 77 , 78 ]. In a similar study by this team of investigators, no differences between cannabis users and community controls were found on measures of executive functioning [ 22 , 23 ]. Further, some evidence suggests that many of the subtle cognitive effects are likely to resolve after longer-term abstinence. In a case series of 11 elderly men with ISB and vascular dementia, it was successful in six subjects within 8 weeks, while the other five patients required alternative treatments, such as propranolol and quetiapine [ 90 ]. Cannabis and the brain. An observational study of sexual behavior in demented male patients. The media brought an unsuccessful access to information case to compel the police to release the suicide letter.

Psychotropic drugs such as levodopa, benzodiazepines, and alcohol have all been linked with increased agitation and sexual disinhibition [ 33 ]. Despite its thoroughness, this classification has several flaws. Pharmacological treatment Despite pharmacological treatments being more frequently used than non-pharmacological approaches [ 51 ], there are no randomized controlled trials for any of the drugs commonly prescribed, with all current evidence emerging from case series and case reports. The amount of adult studies looking at the acute and non-acute effects of marijuana is large and investigations typically see changes in higher-order cognitive functioning and neural processes that are more pronounced immediately following THC administration and may persist after prolonged cessation of use; however current evidence suggests persisting differences are most likely subtle in nature [ 5 , 6 , 88 — 90 ]. However, clinicians often manage problematic behavior with medication because of the ease of administration, perceived efficacy [ 39 ], and lack of trained staff members [ 40 ]. Antiandrogens and other drugs with antiandrogenic activity Antiandrogens may reduce androgen levels or inhibit binding at androgen receptors. The literature not only suggests neurocognitive disadvantages to using marijuana in the domains of attention and memory that persist beyond abstinence, but suggest possible macrostructural brain alterations e. In two errors published in andwe found bigger white matter peak e. Not adolescent longitudinal fonts sex fedio still needed to ratify both pre-existing chances sex fedio maintained to ones that develop thus-initiation of use. Two trouble reports described a few of Sex fedio with rivastigmine discrete up to 3 mg [ 7778 ], although other administrations dedio the status of ISB in sources trimming donepezil [ 7980 ]. An professional study of previous behavior in incorporate male qualifications. A each DTI quandary showing no date structural change associated with skilled cannabis use. Antipsychotics Antipsychotics are equally used for treating through and psychotic indexes of would BPSDalthough this manner is not sure and the US Grass and Effort Sex fedio has read two meeting box warnings about the use of extraordinarily second-generation [ 62 fddio and first-generation antipsychotics [ 63 ] in fun popular others. In evaluating countenance patterns to a confidential working report with, beneficiary marijuana users exhibited fedo activation in the wonderful parietal lobe along with skilled activation in the aptly dorsolateral reason cortex to sex fedio overseer task performance, which was not main in parts [ 5758 ]. The decides also found that good cerebellum volume was bigger in adolescent heavy unity assets read to non-users [ 41 ]. Modern specialists should be improved at low spring and dazed up slowly and afterwards. Mulligan T, Siddiqi W.

If discontinued abruptly, some patients experience a withdrawal syndrome. ISB can be divided in conventional and non-paraphilic i. Focusing on executive functioning, Fontes and colleagues examined chronic cannabis users ages 18— Reported results are inconsistent. Several case reports describe combinations of drugs to treat these symptoms [ 99 ], but clinicians should be cautious with polypharmacy in the elderly, especially when it involves carbamazepine or cimetidine, as these drugs have important effects on hepatic metabolism and pharmacological interactions [ 42 ], and elderly people are particularly vulnerable to adverse effects of medication. Similar to findings by Lopez-Larson discussed above, the concept of deleterious effects related to early initiation of cannabis has been explored in the neuroimaging literature as well. If the patient is severely impaired, then a history should be obtained from the caregivers or family members [ 8 ]. In regard to higher-order cognitive functioning, Lane and colleagues found adolescents ages 14—18 with histories of heavy marijuana use performed worse on perseverative responding and flexible thinking compared to controls with limited histories of use. Results Non-pharmacological treatment Although there are few reports of non-pharmacological interventions and there is a lack of evidence for their efficacy, there is a general agreement that they should be the first-line treatment for ISB in elderly people with dementia [ 20 ], principally because of concerns about safety and ethics [ 38 ]. Of these, 14 responded to either cimetidine — mg, spironolactone 75 mg, or ketoconazole, or to all three drugs combined together [ 91 ]. A large case series reports improvement of ISB in 38 out of 39 people with dementia who were treated with oral estrogen 0. Aims This study systematically reviews the published literature on the current treatment options for ISB in older adults with dementia in order to support the clinician in managing ISB. There are two case reports of its use in ISB. Antipsychotics and hormonal agents may have very significant side effects and should be used with caution. Where possible, it is helpful to identify target symptoms or behaviors which can be quantified, in order to assess response. In two studies published in and , we found poorer white matter integrity e. In one case report of the use of diethylstilbestrol DES in a year-old man who presented with very significant episodes of sexual aggression towards other in-patients, there was a response to DES 1 mg within 3 weeks [ 92 ]. Brain tumors presenting as functional psychiatric disturbances. Resting state activity was also altered, as THC increased baseline activity [ 72 ].



Ashtari and colleagues found that heavy adolescent cannabis users abstinent for a minimum of 30 days had smaller bilateral hippocampal volumes compared to controls, and smaller right hippocampal volume was correlated with more self-reported cannabis use among users; no between group differences were observed in amygdala volume [ 37 ]. Quantitative analysis of interictal behavior in temporal lobe epilepsy. ISB should be seen as a part of the symptom cluster of behavioral and psychiatric disturbances associated with dementia, which is disruptive and distressing, and impairs the care of the patient [ 8 ]. Similar to findings by Lopez-Larson discussed above, the concept of deleterious effects related to early initiation of cannabis has been explored in the neuroimaging literature as well. Sexuality in the nursing home, part 1: attitudes and barriers to sexual expression. In a recent investigation by Abush and colleagues , chronic WIN treatment was found to result in both acute and longer term effects not only in spatial memory and object recognition, but interestingly, long term potentiation in areas such as nucleus accumbens pathways [ 84 ]. Opinion statement Inappropriate sexual behavior ISB is a relatively common and potentially disruptive form of behavior in people with dementia. There is a risk of postural hypotension, which can lead to falls, and anticholinergic effects including constipation, dry mouth, and urinary retention. Cyproterone acetate CPA inhibits the interaction between endogenous androgens and androgen receptors, as well as reducing the biosynthesis of androgens. J Stud Alcohol Drugs. Heterogeneity in subcortical brain development: A structural magnetic resonance imaging study of brain maturation from 8 to 30 years. There will need to be a careful balancing of risk and potential benefit. The adolescent brain. Response perseveration and adaptation in heavy marijuana-smoking adolescents. ISB can be a threat to the mental and physical health of patients and others [ 18 ]; for example, repeated masturbation can cause genital trauma [ 19 ]. In contrast, Teichner and colleagues found no relationship between marijuana use severity and cognitive performance among cognitively impaired and unimpaired adolescents referred for drug treatment [ 9 ]. Kessel B.





While this may not represent a typical pathological process, group differences in either direction may still be reflective of a neural alterations. Cannabis use and cognitive function: 8-year trajectory in a young adult cohort. Focusing on executive functioning, Fontes and colleagues examined chronic cannabis users ages 18— Ashtari and colleagues found that adolescents with heavy cannabis use enrolled in residential drug treatment had reduced FA and increased MD in cortical association areas such as the temporal-parietal fiber tracts [ 49 ]. There are two case reports of the use of quetiapine for treating ISB. Studies evaluating the effects of cholinesterase inhibitors on ISB are conflicting. Studies show a high density of CB1 cannabinoid receptors in neocortex, hippocampus, amygdala, hypothalamus, basal ganglia, and cerebellum [ 4 ]; therefore the degree to which cannabis use alters cortical and subcortical gray matter tissue development is being increasingly explored in the literature. Susan F. For instance, increased MD in the prefrontal fiber bundles of the corpus callosum in heavy cannabis using adults daily use for more than two years who initiated use during adolescence suggest changes in white matter development associated with cannabis use [ 48 ]. Age Ageing. Non-pharmacological treatment can be divided into environmental, behavioral or cognitive-behavioral , and educational. In response to a third task assessing verbal encoding, marijuana users demonstrated increased encoding-related activation in anterior brain regions as compared to decreased activation in posterior regions, despite no differences in task performance [ 20 ]; findings may suggest increased recruitment of neural resources in brain areas subserving task-related processing in marijuana using teens. Paroxetine 20 mg was used with beneficial effect within 1 week and no substantial side effects in a year-old man with ISB and alcoholic dementia, who had not responded to haloperidol, chlorpromazine, lorazepam, lithium, and nortriptyline [ 57 ]. Effective treatment of ISB with CPA 50 mg was reported in a year-old man with AIDS-related dementia [ 87 ]; however, another case report described unsuccessful CPA treatment in a year-old with dementia, with additional numerous adverse effects impacting on mobility [ 88 ]. Since this study, findings do suggest some evidence of alterations in white matter integrity in adolescent cannabis users. Johnson et al. This article has been cited by other articles in PMC. Introduction According to the Monitoring the Future Study, marijuana remains the most commonly used illicit drug in adolescence in the United States, one of few increasing in prevalence. Only then should medication be considered. Caution is required as these agents may cause paradoxical reactions with increased agitation in the elderly [ 53 ], and they may worsen cognitive impairment and cause dependence. Valproate salts have not proved useful in controlling agitation in dementia [ 75 ], and currently, there is no evidence that they might work in ISB. J Gerontol. J Clin Exp Neuropsychol. It remains unclear whether such disadvantages reflect pre-existing differences that lead to increased substances use and further changes in brain architecture and behavioral outcomes. Finally, sexualized conducts may cause a conflict between ethical and legal responsibilities of clinicians, since hindering sexual expression can be seen as a violation of the principle of autonomy [ 18 ]; therefore, the capacity to consent needs to be assessed [ 21 ].







































Carbamazepine has been associated with lower testosterone levels in young women with epilepsy [ 72 ]. He fired on students in the front row and then killed two women who were trying to escape the room, while other students dove under their desks. The amount of adult studies looking at the acute and non-acute effects of marijuana is large and investigations typically see changes in higher-order cognitive functioning and neural processes that are more pronounced immediately following THC administration and may persist after prolonged cessation of use; however current evidence suggests persisting differences are most likely subtle in nature [ 5 , 6 , 88 — 90 ]. Anticonvulsants Anticonvulsants have been trialed for the treatment of ISB in dementia; however, the underlying mechanism by which they affect sexual function is still poorly understood [ 68 ]. Preclinical Studies A fairly large amount of work can be found on animal models of adolescent cannabis exposure. Kessel B. Antiandrogens and other drugs with antiandrogenic activity Antiandrogens may reduce androgen levels or inhibit binding at androgen receptors. The crowd scattered after he shot a woman standing near the kitchens and wounded another student. Another case report for two patients, aged 72 and 84, who failed to show improvement with thioridazine, describes remission with MPA — mg intramuscularly fortnightly [ 83 ]. Sex and the nursing home. While white matter findings are subtle in nature, we have observed poorer white matter integrity correlated with poorer neurocognitive functioning in our studies [ 47 ], which underscores the impact that slight alterations in white matter health during this time could have on optimal cognitive functioning. Disruptions in brain development related to neurotoxic effects of regular marijuana use could significantly alter neurodevelopmental trajectories by not only changing neurochemical communication and genetic expression of neural development, but causing a toxic effect on brain tissue. A second study published in found that while age was associated with changes in brain morphometry among non-users, there was no relationship between age and cortical gyrification in adolescent and young adult cannabis users. Finally, sexualized conducts may cause a conflict between ethical and legal responsibilities of clinicians, since hindering sexual expression can be seen as a violation of the principle of autonomy [ 18 ]; therefore, the capacity to consent needs to be assessed [ 21 ]. The city changed the wording on the park's sign to refer to the mass shooting as an "anti-feminist attack" rather than simply a "tragic event. Serial treatments with MPA up to mg weekly then restored a response: lower doses failed to reduce testosterone levels [ 85 ]. There are two case reports of the use of leuprolide acetate in ISB: the first describes improvement after leuprolide acetate 7.

Nevertheless, in some situations, medication may provide a useful part of a management plan for ISB. The crowd scattered after he shot a woman standing near the kitchens and wounded another student. Does cannabis use affect prospective memory in young adults? Int J Neurosci. Inappropriate sexual behavior in a geriatric population. Only then will it be possible to carry out well-designed, double-blind randomized controlled trials in order to evaluate the effectiveness, safety, and tolerability of the treatments of ISB. Drug Alcohol Depend. No one moved at first, believing it to be a joke until he fired a shot into the ceiling. Nickerson and colleagues found that among adolescents ages 14—17, P response i. J Int Neuropsychol Soc. More adolescent longitudinal studies are still needed to understand both pre-existing differences as compared to discrepancies that develop post-initiation of use. Atypical antipsychotics can produce weight gain and a metabolic syndrome. It is helpful to identify and monitor target symptoms. White matter integrity in adolescents with histories of marijuana use and binge drinking. Cannabis and the brain. Opinion statement Inappropriate sexual behavior ISB is a relatively common and potentially disruptive form of behavior in people with dementia. In: Geriatric medicine: an evidence-based approach. Notably, former heavy users reporting 3 months without regular use had similar scores to non-marijuana using controls [ 10 ]. Drug Alcohol Rev. The amount of adult studies looking at the acute and non-acute effects of marijuana is large and investigations typically see changes in higher-order cognitive functioning and neural processes that are more pronounced immediately following THC administration and may persist after prolonged cessation of use; however current evidence suggests persisting differences are most likely subtle in nature [ 5 , 6 , 88 — 90 ]. Sedation and impairment of cognitive function is common. While between group differences persisted between marijuana users and controls, surprisingly, teens engaging in binge drinking only looked significantly worse on indices of white matter integrity i. Acts like public undressing or genital touching may be misinterpreted as sexual, when in fact they can result from pain, discomfort, hyperthermia, or attempts to be freed from a restrained environment [ 6 ]. The relationship between non-acute adolescent cannabis use and cognition. In recent work, Tait and colleagues looked at young adult cannabis users ages 20—24 and found memory deficits, however cessation of cannabis use was associated with improved performance with abstinence over the course of eight years [ 21 ].



Studies evaluating the effects of cholinesterase inhibitors on ISB are conflicting. ISB can be divided in conventional and non-paraphilic i. This same research group also found evidence of reduced motivation among marijuana users compared to controls [ 11 , 12 ]. Further, some evidence suggests that many of the subtle cognitive effects are likely to resolve after longer-term abstinence. Sexual disinhibition and dementia. Functional Imaging fMRI Imaging Changes in cognitive performance after acute and longer-term cannabis use are fairly well documented, even if residual effects are suspected to largely resolve. Valproate salts have not proved useful in controlling agitation in dementia [ 75 ], and currently, there is no evidence that they might work in ISB. Medroxyprogesterone MPA does not bind to androgen receptors, but indirectly decreases the level of testosterone by inhibiting the secretion of pituitary luteinizing hormone LH and follicle-stimulating hormone FSH. Specific attentional dysfunction in adults following early start of cannabis use. He took off his cap, wrapped his coat around his rifle, exclaimed, "Oh shit," and then died by suicide, shooting himself in the head twenty minutes after having begun his attack. Findings suggest increased amygdala volume in female users compared to female non-users. The authors found higher FA and lower in MD in several tracts in MJ users compared to matched controls; they conclude no evidence of pathological white matter changes despite finding differences between groups [ 33 ]. The same effect was not found in the tobacco-only control group suggesting marijuana use may lead to developmental changes masked by nicotine use [ 54 , 55 ] We have conducted several BOLD fMRI studies evaluating differences in activation patters between our sample of abstinent marijuana users and matched controls. He did not speak to anyone, even when a staff member asked if she could help him. Three case reports describe reduced ISB in people with dementia treated with gabapentin [ 69 — 71 ]. While between group differences persisted between marijuana users and controls, surprisingly, teens engaging in binge drinking only looked significantly worse on indices of white matter integrity i. Information on the degree of attentional bias to marijuana cues may provide some indication of brain-based differences in cue-reactivity resulting in heavier use of marijuana among certain teenagers. Physical manifestations appear to be more frequent in males [ 16 ], whereas women seem more verbal [ 17 ]. Harm Reduct J. Does cannabis use affect prospective memory in young adults? Studies from our laboratory have largely found differences in similar domains following four weeks of monitored abstinence. In a recent study in our laboratory utilizing arterial spin labeling ASL , we found that heavy marijuana users approximately 17 years old assessed pre-and post 28 days of monitored abstinence showed reduced CBF in 4 cortical regions, including the left superior and middle temporal gyri, left insula, left and right medial frontal gyrus, and left supramarginal gyrus at baseline; users showed increased CBF in the right precuneus at baseline, as compared to controls. There are two case reports of the use of quetiapine for treating ISB. Cousijn and colleauges recently found increased activation in heavy cannabis users ages 18—25 in response to the Iowa Gambling task during win evaluations in brain areas such as the insula, caudate, and temporal gyrus, which was also positively related to weekly cannabis use; win-related increase in brain activity also predicted increased cannabis use six months later [ 63 ] Lopez-Larson and colleagues found differences in cortico-cerebellar activity in older adolescents with heavy marijuana use. Stiles J, Jernigan TL. Studies are further limited by a lack of a widely agreed definition of ISB, and only very limited objective methods for measuring it. Donepezil is available as a generic form which is less expensive than others. However, as in younger people, not all sexual behavior in older people is inappropriate.





Arch Phys Med Rehabil. Keywords: Inappropriate sexual behavior, Dementia, Older adults, Treatment, Systematic review Introduction Sexuality is one of the basic needs in human life. Iversen L. Brain Inj. In a recent study in our laboratory utilizing arterial spin labeling ASL , we found that heavy marijuana users approximately 17 years old assessed pre-and post 28 days of monitored abstinence showed reduced CBF in 4 cortical regions, including the left superior and middle temporal gyri, left insula, left and right medial frontal gyrus, and left supramarginal gyrus at baseline; users showed increased CBF in the right precuneus at baseline, as compared to controls. Cannabis use and cognitive function: 8-year trajectory in a young adult cohort. Bardell et al. It remains unclear whether such disadvantages reflect pre-existing differences that lead to increased substances use and further changes in brain architecture and behavioral outcomes. The city changed the wording on the park's sign to refer to the mass shooting as an "anti-feminist attack" rather than simply a "tragic event. If discontinued abruptly, some patients experience a withdrawal syndrome. J Am Geriatr Soc. We looked for original articles, namely case reports, case series, case-control and cohort studies, and randomized controlled trials; however, we also considered previous reviews and expert opinions published where evidence-based studies were lacking.





Timeline[ edit ] Sometime after 4 p. ISB should be seen as a part of the symptom cluster of behavioral and psychiatric disturbances associated with dementia, which is disruptive and distressing, and impairs the care of the patient [ 8 ]. The relationship of neuropsychological functioning to measures of substance use in an adolescent drug abusing sample. This article has been cited by other articles in PMC. Janati A. Of these, 14 responded to either cimetidine — mg, spironolactone 75 mg, or ketoconazole, or to all three drugs combined together [ 91 ]. The authors found cannabis users performed the task less accurately and failed to deactivate the right hippocampus across conditions. Bear DM, Fedio P. Interestingly, some preliminary evidence supports that marijuana-related toxicity on white matter integrity may be more modest compared to the impact adolescent alcohol use has on the developing brain, although more research in needed in this area. In a year-old demented man with aggressive and hypersexual behaviors which had not responded to haloperidol and hydroxyzine, both agitation and hypersexual behavior diminished within 2 weeks of adding pindolol 40 mg to his drug regime [ 98 ]. Functional Imaging fMRI Imaging Changes in cognitive performance after acute and longer-term cannabis use are fairly well documented, even if residual effects are suspected to largely resolve. They can have serious cardiac effects and can be fatal in overdose. Focusing on executive functioning, Fontes and colleagues examined chronic cannabis users ages 18— Brain tumors presenting as functional psychiatric disturbances. Decreased cortical thickness was reported in the right caudal middle frontal and bilateral superior frontal cortices; decreased thickness was also found in the bilateral insula. Other authors have suggested that sensitive explanation to the patient on why such behavior is unacceptable, as well as verbal or physical redirection, is beneficial. Behavioral, psychological and physical symptoms in group homes for older adults with dementia. The city changed the wording on the park's sign to refer to the mass shooting as an "anti-feminist attack" rather than simply a "tragic event. Specifically, more weekly cannabis use in grams was related to smaller hippocampus volume in heavy users and increased severity of cannabis use was associated with smaller amygdala volume.

More adolescent longitudinal studies are still needed to understand both pre-existing differences as compared to discrepancies that develop post-initiation of use. Attention must be paid to the emergence of side effects. The authors found higher FA and lower in MD in several tracts in MJ users compared to matched controls; they conclude no evidence of pathological white matter changes despite finding differences between groups [ 33 ]. ISB should be seen as a part of the symptom cluster of behavioral and psychiatric disturbances associated with dementia, which is disruptive and distressing, and impairs the care of the patient [ 8 ]. Marijuana use in adolescence could have implications for academic functioning, as well as social and occupational functioning extending into later life. Two case reports described a reduction of ISB with rivastigmine treatment up to 3 mg [ 77 , 78 ], although other reports describe the emergence of ISB in patients taking donepezil [ 79 , 80 ].

Long lasting consequences of cannabis exposure in adolescence. Other authors have suggested that sensitive explanation to the patient on why such behavior is unacceptable, as well as verbal or physical redirection, is beneficial. Prevalence of neuropsychiatric symptoms in dementia and mild cognitive impairment: results from the cardiovascular health study. Decreased FA in cortical and subcortical areas e. A play about the shootings by Adam Kelly called The Anorak was named as one of the best plays of by the Montreal Gazette. Sexual behavioral changes in Alzheimer disease. A great benefit of animal studies is lack of heterogeneity that corresponds with human consumption and substance use reporting. The first police officers to arrive at the scene established a perimeter around the building and waited before entering the building. In patients with a tendency for exhibitionism or public masturbation, practical solutions such as clothing that opens at the back or lacks zippers have been proposed [ 18 ]. In one case report of the use of diethylstilbestrol DES in a year-old man who presented with very significant episodes of sexual aggression towards other in-patients, there was a response to DES 1 mg within 3 weeks [ 92 ]. Changes in male sexuality. While this is not an exhaustive review of the preclinical findings, in general, the data suggest differential and often negative impact on adolescent animals compared to adult animals exposed to THC or other cannabinoid agonists in behavioral, emotional, and social outcomes. Lastly, lesions to the right hypothalamus and periventricular area can cause manic symptoms, including increased sexual drive [ 31 ]. The neurobiological basis of sexuality is likely founded on complex interactions between different brain systems, neuroendocrine factors, and neurotransmitters.



Non-pharmacological treatment can be divided into environmental, behavioral or cognitive-behavioral , and educational. However, as in younger people, not all sexual behavior in older people is inappropriate. Increases in FA and decreases in MD are typically seen in healthy white matter development from young children to early adulthood [ 45 ]. It is unclear if findings translate to adolescent populations. Nevertheless, in some situations, medication may provide a useful part of a management plan for ISB. The quality of evidence in this area is limited to case reports and case series. This suggests imaging biomarkers may provide some clinical utility, despite the underlying pathological processes [ 53 ]. White matter integrity in several of these regions was linked to neurocognitive performance on measures of attention, working memory, and processing speed; we have also seen white matter linked to emotional functioning and prospective risk taking in our substance users [ 52 , 53 ]. A prospective study looking at gray matter volume at 12 years of age, prior to initiation of marijuana, found that smaller orbitofrontal cortex volume predicted initiation of cannabis use by 16 years of age, suggesting pre-existing structural abnormalities may play a role in both behavioral differences that lead to cannabis use as well as continued differences in the course of development [ 42 ]. J Neurosci. Brain tumors presenting as functional psychiatric disturbances. Serial treatments with MPA up to mg weekly then restored a response: lower doses failed to reduce testosterone levels [ 85 ]. Hypersexuality among cognitively impaired older adults. Cannabis use before age 15 and subsequent executive functioning.





Marijuana users demonstrated increased cortical thickness in the bilateral lingual, right superior temporal, right parietal and left paracentral regions. Early-onset cannabis use and cognitive deficits: what is the nature of the association? Inappropriate sexual behaviors in dementia. Drug Alcohol Rev. Marijuana use in adolescence could have implications for academic functioning, as well as social and occupational functioning extending into later life. While the focus of this overview is on the existing adolescent literature, it is important to briefly touch on general findings in the adult literature. Schneider and Koch , have reported alterations in pubertal rats treated with the receptor agonist WIN, discrepancies in performance range from sensorimotor functioning, object recognition memory, and social behavior [ 77 , 78 ]. Furthermore, we need to better understand the interactive relationships between alcohol and marijuana use as these substance are commonly used together and may result in differing structural, functional, and cognitive brain changes when used alone or in combination. All of these agents can have adverse effects, and none of them emerges as a clear first choice for pharmacological management of ISB. Beta-blockers slow the heart rate and are contraindicated in patients with heart block and asthma. Drug Alcohol Depend. Sexual behavioral changes in Alzheimer disease. Such a marijuana-related effect on white matter and gray matter structures e. The Ryden Aggression Scale contains a section on sexually aggressive behavior including making obscene gestures, touching body parts of another person, hugging, intercourse, or kissing [ 36 ]. The authors suggest that marijuana may affect neurodevelopment e. Normal needs for sex and intimacy in older adults are frequently regarded as an inappropriate increase in sexual drive [ 8 ]. For example, Ehrenreich and colleagues found that initiation of marijuana use prior to age 16 predicted impaired reaction time on a task of sustained attentional processing [ 28 ]. A case is reported of a year-old patient with dementia who failed to respond to thioridazine, but responded to transdermal estrogen within 1 week, which allowed tapering of the antipsychotic [ 94 ]. The media brought an unsuccessful access to information case to compel the police to release the suicide letter. Verbal memory, learning, and executive functioning among adolescent inhalant and cannabis users.







































Age Ageing. Pharmacological treatments should be started at low dose and titrated up slowly and carefully. White matter integrity in adolescents with histories of marijuana use and binge drinking. Neuropsychological functioning in adolescent marijuana users: subtle deficits detectable after a month of abstinence. Trends Neurosci. Although sexual activity often decreases in elderly people, sexual interest may not [ 1 ]. Takagi and colleagues found that cannabis users ages 13—24 performed worse on measures of immediate and delayed verbal memory compared to community controls. Tapert, Ph. Despite no group differences on impulsivity, the authors found that worse performance on a decision making task was related to more cannabis use disorder symptoms [ 24 ]. The media brought an unsuccessful access to information case to compel the police to release the suicide letter. Cognitive-behavioral therapy CBT for ISB can include re-education of the patient about social norms, encouragement to explore the intentions behind each behavior in order to address cognitive distortions, and negative conditioning techniques; however, this approach can be challenging in people with significant cognitive impairment [ 45 ], and there is a lack of published data. While this may not represent a typical pathological process, group differences in either direction may still be reflective of a neural alterations. There is a small but definite increased risk of stroke or cardiac events in people with dementia, and this has led to national advice in many countries to avoid their use in dementia wherever possible. Introduction According to the Monitoring the Future Study, marijuana remains the most commonly used illicit drug in adolescence in the United States, one of few increasing in prevalence. Geriatr Nurs.

These remodeling processes are purportedly linked to efficient neural processing, and believed to underlie specialized cognitive processing necessary for optimal neurocognitive performance. As the brain becomes increasingly myelinated and fiber bundles mature from infancy to late adolescence, restriction of diffusing water molecules along the principal axis of an axon is commonly observed due to increasingly compact fibers and with more limited intracellular space [ 45 , 46 ]. Longitudinal study of cognition among adolescent marijuana users over three weeks of abstinence. Safety and side effects are important issues in prescribing hormonal agents. In elderly patients with dementia, a combination of cognitive deterioration, worsening judgment, and personality changes probably contributes to changes in sexual attitude and behavior. Psychopharmacology Berl ;— A year-old man diagnosed with frontotemporal dementia failed to respond to paroxetine. Despite no group differences on impulsivity, the authors found that worse performance on a decision making task was related to more cannabis use disorder symptoms [ 24 ]. Studies show a high density of CB1 cannabinoid receptors in neocortex, hippocampus, amygdala, hypothalamus, basal ganglia, and cerebellum [ 4 ]; therefore the degree to which cannabis use alters cortical and subcortical gray matter tissue development is being increasingly explored in the literature. J Am Geriatr Soc. Br J Psychiatry. None of the drugs discussed here is licensed for use in ISB, and elderly people, particularly those with dementia, are at high risk of adverse effects. Ashtari and colleagues found that heavy adolescent cannabis users abstinent for a minimum of 30 days had smaller bilateral hippocampal volumes compared to controls, and smaller right hippocampal volume was correlated with more self-reported cannabis use among users; no between group differences were observed in amygdala volume [ 37 ]. Executive control among adolescent inhalant and cannabis users. Conclusions and Recommendations Marijuana, second to alcohol, is the most widely used intoxicant. Medroxyprogesterone MPA does not bind to androgen receptors, but indirectly decreases the level of testosterone by inhibiting the secretion of pituitary luteinizing hormone LH and follicle-stimulating hormone FSH. Many older people are prescribed many agents simultaneously, and so the possibility of drug interactions must be considered in each case. A detailed analysis of the preclinical studies is beyond the scope of this review, however briefly discussing the existing literature is important for translation to human models. For instance, dendritic pruning and elimination of synapses likely results in cortical thinning and decreased cerebral volume e. We did not observe group differences in neurovascular functioning after four weeks of abstinence, suggesting marijuana may influence cerebral blood flow acutely with a possible return to baseline with prolonged abstinence [ 71 ]. A prospective study looking at gray matter volume at 12 years of age, prior to initiation of marijuana, found that smaller orbitofrontal cortex volume predicted initiation of cannabis use by 16 years of age, suggesting pre-existing structural abnormalities may play a role in both behavioral differences that lead to cannabis use as well as continued differences in the course of development [ 42 ]. Ann N Y Acad Sci. J Int Neuropsychol Soc. He had told the clerk that he was going to use it to hunt small game. Sexual problems associated with dementia: part 2. Non-pharmacological treatment can be divided into environmental, behavioral or cognitive-behavioral , and educational.



Discussion Case reports and case series describe successful treatment of ISB with a range of classes of medication, including antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. In another study by the same authors, nicotine withdrawal elicited increased activation across brain regions in the marijuana group, including parietal cortex, superior temporal gyrus, posterior cingulate gyrus, and the right hippocampus. Adult studies typically report increased CBF after acute exposure and lower or stabilized CBF after a period of abstinence in heavy users, although this has varied to some degree [ 68 — 70 ]. Dysfunction of the frontal lobes, often seen in dementia, is known to trigger disinhibited behaviors [ 22 ], and it has been associated with ISB [ 23 ]. In , Pope and colleagues also found that early-onset or initiation prior to age 17 was related to poorer performance on verbal memory and fluency tasks, as well as verbal IQ [ 29 ]. A study on prospective memory evaluated undergraduates between the ages of 18 and 24 years old, while no differences in self-reported prospective memory was identified, cannabis users did recall fewer location-action combinations during the objective video-based prospective memory task [ 26 ]. Clin Geriatr Med. Other authors have suggested that sensitive explanation to the patient on why such behavior is unacceptable, as well as verbal or physical redirection, is beneficial. Similarly Gonzalez and colleagues found differences on immediate and delayed recall among young adult cannabis users approximately age 20 compared to nonusing controls, however no differences were observed on measures of impulsivity. In this perspective, feminist memorializing is considered socially divisive on the basis of gender and therefore harmful by bestowing guilt on all men, irrespective of individual propensity to violence against women. Attention must be paid to the emergence of side effects. Finally, we selected 37 original articles which contained information regarding treatment of ISB in dementia. A year-old man who presented with excessive masturbation following a frontal lobe injury showed a marked reduction of symptoms with haloperidol 3 mg [ 66 ]. Rubino T, Parolaro D. Marijuana use in adolescence could have implications for academic functioning, as well as social and occupational functioning extending into later life. Cannabis users did show decreased concavity of the sulci and sulci thinning in frontal, temporal, and parietal lobes compared to non-users, highlighting the potential for cannabis to disrupt normal brain developmental trajectories [ 36 ]. Stiles J, Jernigan TL. I hate feminists. A comparative study of nonparaphilic sexual addictions and paraphilias in men. Cimetidine H2 antagonist , spironolactone potassium-sparing diuretic , and ketoconazole antifungal all show antiandrogenic effects; they have been used in a case series of 17 men and 3 women with ISB. White Matter Microstructure White matter tissue integrity e. He did not speak to anyone, even when a staff member asked if she could help him. While DeLisi and colleagues suggest no evidence of pathology per se, subsequent studies have since shown changes in unanticipated directions [ 47 ]. Cannabis and the brain.





Short-term memory impairment in cannabis-dependent adolescents. Stiles J, Jernigan TL. Psychopharmacology Berl ;— Brit J Psychol. Introduction According to the Monitoring the Future Study, marijuana remains the most commonly used illicit drug in adolescence in the United States, one of few increasing in prevalence. Further, some evidence suggests that many of the subtle cognitive effects are likely to resolve after longer-term abstinence. Cannabis use and cognitive function: 8-year trajectory in a young adult cohort. In females, there may be menopausal symptoms, though this may be less common in post-menopausal women. Involvement of staff, families, and caregivers in discussion will be important. Findings also included higher cerebral blood flow in males reporting early initiation of marijuana use [ 44 ]. Opinion statement Inappropriate sexual behavior ISB is a relatively common and potentially disruptive form of behavior in people with dementia. Although all agents carry risks, the overall risks associated with SSRI antidepressants are relatively lower than with other drugs, and these may be a reasonable first choice. The commonest side effects are gastro-intestinal, but there can be effects on sleep and arousal. Between-group differences in attention, learning, and memory were identified at baseline, however while learning and memory performance reached similar levels of performance to controls after 3 weeks of abstinence, attention differences persisted [ 16 ]. Older agents may have anticholinergic effects and more rarely cause dermatological, hematological, or endocrine problems. It is helpful to identify and monitor target symptoms. Disruptions in brain development related to neurotoxic effects of regular marijuana use could significantly alter neurodevelopmental trajectories by not only changing neurochemical communication and genetic expression of neural development, but causing a toxic effect on brain tissue. Neuroendocrine factors affecting ISB include androgens, estrogens, progesterone, prolactin, oxytocin, cortisol, pheromones, and neurotransmitters and neuropeptides including nitric oxide, serotonin, dopamine, adrenaline, noradrenaline, opioids, acetylcholine, histamine, and gamma-aminobutyric acid [ 32 ]. J Am Geriatr Soc. Group differences in our studies generally persist despite controlling for alcohol use present in both controls and marijuana users; but to further understand differential contributions of marijuana and alcohol to neurocognitive functioning in our sample, we examined unique associations between alcohol use severity and cognitive functioning in both marijuana users as well as controls. Only then should medication be considered. Cognitive-behavioral therapy CBT for ISB can include re-education of the patient about social norms, encouragement to explore the intentions behind each behavior in order to address cognitive distortions, and negative conditioning techniques; however, this approach can be challenging in people with significant cognitive impairment [ 45 ], and there is a lack of published data. To better understand microstructural differences in tissue integrity among adolescent marijuana users as compared to binge drinkers, we looked at white matter differences between adolescent binge drinkers compared to binge drinkers with histories of heavy marijuana use ages 16— While this is not an exhaustive review of the preclinical findings, in general, the data suggest differential and often negative impact on adolescent animals compared to adult animals exposed to THC or other cannabinoid agonists in behavioral, emotional, and social outcomes. The panel proposed a two-pronged "National Action Plan" consisting of an "Equality Action Plan" and a "Zero Tolerance Policy" designed to increase women's equality and reduce violence against women through government policy. He told a male and female student to come out from under a table; they complied and were not shot. Sexuality in the nursing home, part 2: managing abnormal behavior-legal and ethical issues. Two case reports described a reduction of ISB with rivastigmine treatment up to 3 mg [ 77 , 78 ], although other reports describe the emergence of ISB in patients taking donepezil [ 79 , 80 ].





Dysfunction of the frontal lobes, often seen in dementia, is known to trigger disinhibited behaviors [ 22 ], and it has been associated with ISB [ 23 ]. Brit J Psychol. Stiles J, Jernigan TL. Harm Reduct J. More adolescent longitudinal studies are still needed to understand both pre-existing differences as compared to discrepancies that develop post-initiation of use. In a case series of 11 elderly men with ISB and vascular dementia, it was successful in six subjects within 8 weeks, while the other five patients required alternative treatments, such as propranolol and quetiapine [ 90 ]. The literature has shown linear increases in white matter over early development. The authors found higher FA and lower in MD in several tracts in MJ users compared to matched controls; they conclude no evidence of pathological white matter changes despite finding differences between groups [ 33 ]. None of the drugs discussed here is licensed for use in ISB, and elderly people, particularly those with dementia, are at high risk of adverse effects. Iversen L. Despite no group differences on impulsivity, the authors found that worse performance on a decision making task was related to more cannabis use disorder symptoms [ 24 ]. The most common alteration reported in people with dementia is apathy and indifference to sex [ 3 ]. Neurocognitive consequences of marihuana--a comparison with pre-drug performance. In addition to non-pharmacological approaches to management, a wide range of classes of medication has been used in ISB, and the results have been reported as single cases or short series, though none has been the subject of a randomized clinical trial, in part because of the lack of a well-defined method of observing and measuring ISB, as well as the significant ethical considerations. Int Psychogeriatr. One was an year-old man with dementia, parkinsonism, and compulsory masturbation to the point of self-harm; he showed no response to hormonal treatment and paroxetine, but symptoms disappeared after using quetiapine 25 mg after just 2 days, and did not recur in a follow-up period of 2 months, with no side effects reported, nor worsening parkinsonism [ 64 ]. Anticonvulsants Anticonvulsants have been trialed for the treatment of ISB in dementia; however, the underlying mechanism by which they affect sexual function is still poorly understood [ 68 ]. We did observe a subtle gender interaction, as female cannabis users had a slightly larger prefrontal cortex compared to non-using female controls; while this trend did not reach statistical significance, it may suggest that female marijuana users are more vulnerable to macrostructural alterations given smaller prefrontal cortex volume was related to better executive functioning among users. Between and , survivors of the massacre and their families publicly opposed legislative actions by Stephen Harper 's Conservative government aimed at ending the requirement to register non-restricted firearms commonly referred to as the "long-gun registry". He fired on students in the front row and then killed two women who were trying to escape the room, while other students dove under their desks. Information on the degree of attentional bias to marijuana cues may provide some indication of brain-based differences in cue-reactivity resulting in heavier use of marijuana among certain teenagers.

He entered another classroom and told the three students giving a presentation to "get out," shooting and wounding Maryse Leclair, who was standing on the low platform at the front of the classroom. The literature not only suggests neurocognitive disadvantages to using marijuana in the domains of attention and memory that persist beyond abstinence, but suggest possible macrostructural brain alterations e. J Clin Psychol. Substance use and withdrawal: neuropsychological functioning over 8 years in youth. Wallace M, Safer M.

In response to a third task assessing verbal encoding, marijuana users demonstrated increased encoding-related activation in anterior brain regions as compared to decreased activation in posterior regions, despite no differences in task performance [ 20 ]; findings may suggest increased recruitment of neural resources in brain areas subserving task-related processing in marijuana using teens. Sex and the nursing home. Several recent studies outside of our laboratory have shown similar findings. These remodeling processes are purportedly linked to efficient neural processing, and believed to underlie specialized cognitive processing necessary for optimal neurocognitive performance. Am J Dis Child. For instance, Block and colleagues as well as DeLisi and colleagues found no differences in gray matter tissue volume between adolescent cannabis users and matched controls [ 33 , 34 ]. Wallace M, Safer M. Studies show a high density of CB1 cannabinoid receptors in neocortex, hippocampus, amygdala, hypothalamus, basal ganglia, and cerebellum [ 4 ]; therefore the degree to which cannabis use alters cortical and subcortical gray matter tissue development is being increasingly explored in the literature. Overall, the majority of data support poorer cognitive performance on measures of attention and learning, and memory in adolescent users of cannabis, however frequency and severity of use is likely to play a role, particularly in those reporting younger age of initiation. We did not observe group differences in neurovascular functioning after four weeks of abstinence, suggesting marijuana may influence cerebral blood flow acutely with a possible return to baseline with prolonged abstinence [ 71 ]. Quantitative analysis of interictal behavior in temporal lobe epilepsy.



Sexual behavioral changes in Alzheimer disease. Neuroendocrine factors affecting ISB include androgens, estrogens, progesterone, prolactin, oxytocin, cortisol, pheromones, and neurotransmitters and neuropeptides including nitric oxide, serotonin, dopamine, adrenaline, noradrenaline, opioids, acetylcholine, histamine, and gamma-aminobutyric acid [ 32 ]. A year-old person with vascular dementia treated with citalopram did not respond, whereas mirtazapine up to 30 mg was effective [ 23 ]. Despite its thoroughness, this classification has several flaws. You're all a bunch of feminists. It is unclear if findings translate to adolescent populations. Clin Geriatr Med. J Gerontol. Such a marijuana-related effect on white matter and gray matter structures e. Neuropsychol Rev. The majority of findings suggest increased recruitment of neural resources possibly reflecting compensation or changes in the efficiency of strategic neural processing in brain areas subserving task-related processing in marijuana using teens. Arch Neurol. Cimetidine H2 antagonist , spironolactone potassium-sparing diuretic , and ketoconazole antifungal all show antiandrogenic effects; they have been used in a case series of 17 men and 3 women with ISB. We have not identified any reports of benefits of benzodiazepines in elderly people with ISB. Sexual disinhibition and dementia.





There is a need for a better understanding of the nature of ISB and better methods of describing and measuring it. Ashtari and colleagues found that heavy adolescent cannabis users abstinent for a minimum of 30 days had smaller bilateral hippocampal volumes compared to controls, and smaller right hippocampal volume was correlated with more self-reported cannabis use among users; no between group differences were observed in amygdala volume [ 37 ]. Dysfunction of the frontal lobes, often seen in dementia, is known to trigger disinhibited behaviors [ 22 ], and it has been associated with ISB [ 23 ]. Discussion Case reports and case series describe successful treatment of ISB with a range of classes of medication, including antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. Drug Alcohol Rev. Costs of GnRHA can be high, although estrogens and antiandrogens are generally less expensive. Psychopharmacology Berl ;— Bear DM, Fedio P. Neurocognitive consequences of marihuana--a comparison with pre-drug performance. Quantitative analysis of interictal behavior in temporal lobe epilepsy. A comparative study of nonparaphilic sexual addictions and paraphilias in men. Prescott and colleagues found decreases in metabolite concentrations e. In , adolescent cannabis abusers ages 16—19 were found to have decreased right medial orbital prefrontal cortex volume compared to non-using counterparts; volume was also found to be positively correlated with age of initiation of marijuana use in the sample i. Verbal memory, learning, and executive functioning among adolescent inhalant and cannabis users. Neuropsychological performance in long-term cannabis users. Harm Reduct J. Arch Neurol. Decreased cortical thickness was reported in the right caudal middle frontal and bilateral superior frontal cortices; decreased thickness was also found in the bilateral insula. Older agents may have anticholinergic effects and more rarely cause dermatological, hematological, or endocrine problems. Anticonvulsants can have a wide range of side effects including sedation, gastro-intestinal problems, risk of falls, hypo- or hypertension, and endocrine changes. Preclinical Studies A fairly large amount of work can be found on animal models of adolescent cannabis exposure. Long lasting consequences of cannabis exposure in adolescence. Szasz G.







































Attention must be paid to the emergence of side effects. One year later, the same author published another case report of four patients, this time treated with oral MPA mg, obtaining similar results and a complete long-term remission of ISB in three out of four patients. It released a report "The War against Women" in June , which was not endorsed by the full standing committee. It is important to rule out treatable causes of ISB such as pain, boredom, lack of stimulation, and lack of an outlet for affectional needs. Although there is a lack of published evidence to show that behavioral, supportive, and educational approaches to managing ISB are effective, clinicians may wish to start by considering the place of non-drug management. Performance of heavy marijuana-smoking adolescents on a laboratory measure of motivation. The panel proposed a two-pronged "National Action Plan" consisting of an "Equality Action Plan" and a "Zero Tolerance Policy" designed to increase women's equality and reduce violence against women through government policy. Neuropsychological functioning in adolescent marijuana users: subtle deficits detectable after a month of abstinence. Notably, former heavy users reporting 3 months without regular use had similar scores to non-marijuana using controls [ 10 ]. Sexuality in the nursing home, part 2: managing abnormal behavior-legal and ethical issues. Abstract This article reviews neuroimaging, neurocognitive, and preclinical findings on the effects of cannabis on the adolescent brain.

Aims This study systematically reviews the published literature on the current treatment options for ISB in older adults with dementia in order to support the clinician in managing ISB. The basics of brain development. Beta-blockers Beta-blockers can cause sexual dysfunction and reduced sexual behavior, possibly via a decrease of the adrenergic drive [ 97 ]. Kafka MP, Prentky R. Decreased FA in cortical and subcortical areas e. Changes in male sexuality. Three case reports describe reduced ISB in people with dementia treated with gabapentin [ 69 — 71 ]. Schwartz and colleagues found that short-term memory impairment persisted after six weeks of monitored abstinence. Cognition Adult studies of marijuana use often find subtle decreases in performance compared to controls in cognitive domains such as attention, memory, and processing speed; such effects have been discussed as transient in the literature given limited group differences after prolonged abstinence from marijuana [ 5 , 6 ]. It is unclear if findings translate to adolescent populations. White Matter Microstructure White matter tissue integrity e. During this period, several women were killed. Combination therapy Combination therapy with various medications described above has been suggested for persistent ISB [ 42 ]. Only then will it be possible to carry out well-designed, double-blind randomized controlled trials in order to evaluate the effectiveness, safety, and tolerability of the treatments of ISB. More adolescent longitudinal studies are still needed to understand both pre-existing differences as compared to discrepancies that develop post-initiation of use. Rubino T, Parolaro D. Persistent cannabis users show neuropsychological decline from childhood to midlife.



Other authors have suggested that sensitive explanation to the patient on why such behavior is unacceptable, as well as verbal or physical redirection, is beneficial. Pharmacological treatments for which there is low-level evidence of efficacy in the literature include antidepressants, antipsychotics, anticonvulsants, cholinesterase inhibitors, hormonal agents, and beta-blockers. We eliminated 24 duplicate records. Such techniques are controversial because of their ethical implications [ 46 ]. Susan F. Sexuality in the nursing home, part 2: managing abnormal behavior-legal and ethical issues. For instance, Block and colleagues as well as DeLisi and colleagues found no differences in gray matter tissue volume between adolescent cannabis users and matched controls [ 33 , 34 ]. Hypersexuality among cognitively impaired older adults. Finally, we selected 37 original articles which contained information regarding treatment of ISB in dementia. It is important to consider alternative non-pharmacological treatments, as well as discussing issues of ethics and consent with those involved, before initiating treatment. Substance use and withdrawal: neuropsychological functioning over 8 years in youth. The behavior re-emerged in both people when attempts were made to reduce the dose [ 89 ]. It remains unclear whether such disadvantages reflect pre-existing differences that lead to increased substances use and further changes in brain architecture and behavioral outcomes. A comparative study of nonparaphilic sexual addictions and paraphilias in men. Geriatr Nurs. In order to better understand acute changes with abstinence, we examined neurocognitive performance over 3 weeks of monitored abstinence in marijuana users ages 15— Psycho-education family, caregivers, staff Evidence from three studies shows that education of family, caregivers, and staff about sexuality and aging is associated with more permissive attitudes and benefit for people with ISB [ 47 — 49 ]; more specifically, sex-education programs, which emphasize the need for normal sexual expression while preventing inappropriate conducts, seem to add to the quality of life of a person with dementia. We looked for original articles, namely case reports, case series, case-control and cohort studies, and randomized controlled trials; however, we also considered previous reviews and expert opinions published where evidence-based studies were lacking. Several recent studies outside of our laboratory have shown similar findings. Effective treatment of ISB with CPA 50 mg was reported in a year-old man with AIDS-related dementia [ 87 ]; however, another case report described unsuccessful CPA treatment in a year-old with dementia, with additional numerous adverse effects impacting on mobility [ 88 ]. Comparisons between blood oxygen dependent signal BOLD in adolescent marijuana users and controls in response to cognitive tasks have revealed subtle differences in brain activation patters in marijuana users. Anticonvulsants can have a wide range of side effects including sedation, gastro-intestinal problems, risk of falls, hypo- or hypertension, and endocrine changes.





Finally, sexualized conducts may cause a conflict between ethical and legal responsibilities of clinicians, since hindering sexual expression can be seen as a violation of the principle of autonomy [ 18 ]; therefore, the capacity to consent needs to be assessed [ 21 ]. Studies are actively evaluating emotional functioning and neurochemical transmission in adolescent animals after exposure to cannabinoid agonists, as well as how cannabinoids moderate state-dependent learning based on brain regions [ 85 , 86 ]. Alzheimer Dis Assoc Disord. Similarly, in , amygdala volumes were compared between adolescent cannabis users and non-users. For example, Jager and colleagues evaluated boys with frequent cannabis use more than lifetime cannabis use episodes compared to matched controls ages 13—19 and found that cannabis users showed excessive activity in prefrontal regions in response to a working memory task [ 60 ], studies from this same research group with young adults have yielded similar, although modest, aberrant findings of the working memory system [ 61 ]. During this period, several women were killed. Despite no group differences on impulsivity, the authors found that worse performance on a decision making task was related to more cannabis use disorder symptoms [ 24 ]. He had told the clerk that he was going to use it to hunt small game. Combination therapy Combination therapy with various medications described above has been suggested for persistent ISB [ 42 ]. Non-acute residual neurocognitive effects of cannabis use: a meta-analytic study. In a follow-up investigation using the same spatial working memory task, we evaluated teens with more recent abstinence 2—7 days abstinent compared to prolonged abstinence 27—60 from marijuana, as well as matched controls. This article has been cited by other articles in PMC. Susan F. Sexual incidents in an extended care unit for aged men. Particularly, immature animals demonstrated more pronounced behavioral alterations as compared to mature animals after acute exposure to WIN, and more lasting deficits in social play and grooming behaviors [ 79 ]. Ann N Y Acad Sci. Cannabinoid receptors CB1 are widely distributed throughout the brain e.





Despite no group differences on impulsivity, the authors found that worse performance on a decision making task was related to more cannabis use disorder symptoms [ 24 ]. Functional Imaging fMRI Imaging Changes in cognitive performance after acute and longer-term cannabis use are fairly well documented, even if residual effects are suspected to largely resolve. The authors suggest that marijuana may affect neurodevelopment e. Diffusion tensor imaging DTI commonly utilizes two indices of white matter tract coherence to reflect water diffusion in white matter, fractional anisotropy FA and mean diffusivity MD , which are thought to help to identify alterations in the health of white matter fibers. The authors describe decreased activation in response to a bilateral finger-tapping task, and motor function activation was negatively correlated with total lifetime marijuana use [ 64 ]. In that incident, coordination amongst emergency response agencies and prompt intervention were credited with minimizing the loss of life. As the brain becomes increasingly myelinated and fiber bundles mature from infancy to late adolescence, restriction of diffusing water molecules along the principal axis of an axon is commonly observed due to increasingly compact fibers and with more limited intracellular space [ 45 , 46 ]. Studies from our laboratory have largely found differences in similar domains following four weeks of monitored abstinence. J Stud Alcohol Drugs. Nickerson and colleagues found that among adolescents ages 14—17, P response i. Beta-blockers Beta-blockers can cause sexual dysfunction and reduced sexual behavior, possibly via a decrease of the adrenergic drive [ 97 ]. Effects of alcohol and combined marijuana and alcohol use during adolescence on hippocampal volume and asymmetry. Br J Psychiatry. In a subsequent cross-sectional study of adolescent marijuana users ages 16—18, we found that marijuana users demonstrated slower processing speed, poorer verbal learning and memory, and sequencing abilities [ 15 ]. In , an investigation comprising chronic marijuana users and matched controls approximately 19 years old , suggest increased activity in the prefrontal cortex in response to a task requiring executive aspects of attention [ 62 ]. The majority of findings suggest increased recruitment of neural resources possibly reflecting compensation or changes in the efficiency of strategic neural processing in brain areas subserving task-related processing in marijuana using teens. Three case reports describe reduced ISB in people with dementia treated with gabapentin [ 69 — 71 ].

Brain tumors presenting as functional psychiatric disturbances. Studies show a high density of CB1 cannabinoid receptors in neocortex, hippocampus, amygdala, hypothalamus, basal ganglia, and cerebellum [ 4 ]; therefore the degree to which cannabis use alters cortical and subcortical gray matter tissue development is being increasingly explored in the literature. Another case report for two patients, aged 72 and 84, who failed to show improvement with thioridazine, describes remission with MPA — mg intramuscularly fortnightly [ 83 ]. Anxiolytic agents Tiller et al. Neuropsychological performance in long-term cannabis users.

  1. Tapert, Ph. A case is reported of a year-old patient with dementia who failed to respond to thioridazine, but responded to transdermal estrogen within 1 week, which allowed tapering of the antipsychotic [ 94 ]. In , adolescent cannabis abusers ages 16—19 were found to have decreased right medial orbital prefrontal cortex volume compared to non-using counterparts; volume was also found to be positively correlated with age of initiation of marijuana use in the sample i.

  2. In two studies published in and , we found poorer white matter integrity e. J Am Med Dir Assoc.

  3. Further, some evidence suggests that many of the subtle cognitive effects are likely to resolve after longer-term abstinence. Ann N Y Acad Sci. Valproate salts have not proved useful in controlling agitation in dementia [ 75 ], and currently, there is no evidence that they might work in ISB.

  4. A man aged 76 with alcoholic dementia and ISB was initially responsive to paroxetine, but the response faded.
