RESUMO

BACKGROUND: Intellectual disability (ID), schizophrenia spectrum disorder (SSD), bipolar disorder (BD), substance use disorder (SUD), and other mental disorders (OMDs) are associated with increased risks of criminality relative to sex-matched individuals without these conditions (NOIDMD). To resource psychiatric, addiction, and social services so as to provide effective treatments, further information is needed about the size of sub-groups convicted of crimes, recidivism, timing of offending, antecedents, and correlates. Stigma of persons with mental disorders could potentially be dramatically reduced if violence was prevented. METHODS: A birth cohort of 14,605 persons was followed to age 64 using data from Swedish national health, criminal, and social registers. RESULTS: Percentages of group members convicted of violence differed significantly: males NOIDMD, 7.3%, ID 29.2%, SSD 38.6%, BD 30.7%; SUD 44.0%, and OMD 19.3%; females NOIDMD 0.8%, ID 7.7%, SSD 11.2%, BD 2.4%, SD 17.0%, and OMD 2.1%. Violent recidivism was high. Most violent offenders in the diagnostic groups were also convicted of non-violent crimes. Prior to first diagnosis, convictions (violent or non-violent) had been acquired by over 90% of the male offenders and two-thirds of the female offenders. Physical victimization, adult comorbid SUD, childhood conduct problems, and adolescent substance misuse were each associated with increased risks of offending. CONCLUSION: Sub-groups of cohort members with ID or mental disorders were convicted of violent and non-violent crimes to age 64 suggesting the need for treatment of primary disorders and for antisocial/aggressive behavior. Many patients engaging in violence could be identified at first contact with clinical services.

RESUMO

Objective Mental health services for persons presenting a first episode of psychosis include specialized interventions that are effective in treating psychosis, but they do not include treatments that prevent aggressive behaviour (AB). This article presents the results of studies in an effort to incite these services to evaluate the risk of AB and to intervene rapidly to prevent these behaviours as well as treating the psychotic disorder. Method This article presents a narrative review of the scientific studies. We have reviewed publications in French and English reporting studies, reviews, and meta-analyses focused on the antecedents, correlates, and effective treatments for AB and criminality of persons described as presenting severe mental disorder, schizophrenia, or a first episode of psychosis. Results The review of scientific studies confirms that persons developing or presenting schizophrenia are at increased risk to engage in AB, crime, and homicide relative to the general population. Before a first episode of psychosis approximately one third of patients display AB. One subgroup of these persons, those who present the highest risk of AB and criminality, have a history of conduct disorder since childhood. Another subgroup who also begin engaging in AB before a first episode of psychosis display AB as anxiety and positive symptoms increase. The association between positive psychotic symptoms and AB varies according to the phase of illness and the age of onset of AB. Further, other factors such as substance misuse (especially cannabis use), difficulty in recognizing emotions in the faces of others, impulsivity, and physical victimization are related to AB. In addition to effective treatments for psychosis and social skill training, treatment programs aimed at preventing AB and antisocial behaviours, and the associated factors are needed, as well as interventions that aim to reduce victimization. Conclusion The extant literature identifies different profiles of patients and factors associated with AB that can be identified at a first episode of psychosis. Consequently, first episode services could play an important role in preventing AB. To do this, they would need to simultaneously treat the psychosis and the AB. The implementation of such treatments would involve challenges such as convincing treatment teams of the benefits of such an approach and convincing patients needing these treatments to comply. Increasing patients' motivation and compliance remains an important challenge.

RESUMO

OBJECTIVE: Some persons developing, or presenting, schizophrenia engage in aggressive behaviour (AB) and/or criminal offending. Most of these individuals display AB prior to a first episode of psychosis (FEP). In fact, approximately one-third of FEP patients have a history of AB, some additionally display other antisocial behaviours (A+AB). The large majority of these individuals have presented conduct problems since childhood, benefit from clozapine, have extensive treatment needs, and are unlikely to comply with treatment. A smaller sub-group begin to engage in AB as illness onsets. A+AB persists, often for many years in spite of treatment-as-usual, until a victim is seriously harmed. This article proposes providing multi-component treatment programs at FEP in order to prevent aggressive and antisocial behaviours of persons with schizophrenia. METHOD: Non-systematic reviews of epidemiological studies of AB among persons with schizophrenia, of the defining characteristics of sub-types of persons with schizophrenia who engage in AB and their responses to treatment, and of FEP service outcomes. RESULTS: Studies have shown that mental health services that simultaneously target schizophrenia and aggressive behaviour are most effective both in reducing psychotic symptoms and aggressive behaviour. Evidence, although not abundant, suggests that a multi-component treatment program that would include the components recommended to treat schizophrenia and cognitive-behavioural interventions to reduce A+AB, and the other factors promoting A+AB such as substance misuse, victimisation, and poor recognition of emotions in the faces of others has the potential to effectively treat schizophrenia and reduce A+AB. Patients with a recent onset of AB would require few components of treatment, while those with prior conduct disorder would require all. Such a program of treatment would be long and intense. CONCLUSIONS: Trials are needed to test the effectiveness of multi-component treatment programs targeting schizophrenia and A+AB at FEP. Studies are also necessary to determine whether providing such programs in hospitals and/or prisons, with long-term community after-care, and in some cases with court orders to participate in treatment, would enhance effectiveness. Whether investing at FEP would be cost-effective requires investigation.

RESUMO

The percentage of forensic psychiatric patients who are female varies from 5 to 13% in Europe, rises to 18% in England and Wales, and sits at 15% in Canada. Similarly, many fewer women than men are incarcerated in correctional facilities. While these statistics supposedly reflect less antisocial and aggressive behavior (AAB) among females than males, not all findings support this supposition. Data from prospective longitudinal studies show that aggressive and antisocial behavior onsets in childhood, and in a small group of females it remains stable across the life-span. Unlike similar males, few of these females are convicted of crimes. This article begins with a review of descriptive studies of females sentenced by criminal courts to treatment in forensic psychiatric hospitals and moves on to present evidence showing that most female AAB does not lead to criminal prosecution. Next, studies of female AAB are reviewed, noting that it onsets in early childhood and, that in a small group remains stable across the life-span. Subsequent sections of the article focus on the two most common mental disorders presented by female forensic patients, schizophrenia and borderline personality disorder, highlighting what is known about the sub-groups of women with these disorders who present AAB. The article concludes with recommendations for earlier identification by psychiatric services of women presenting mental disorders and AAB, treatments to reduce both the symptoms of their mental disorders and their life-long AAB, and the research that is needed in order to improve the effectiveness of these treatments. The real possibilities of prevention of the development of AAB, and even perhaps aspects of the mental disorders that plague female forensic patients, are described.

RESUMO

Epigenome-wide studies report higher methylation among women than men with decreasing levels with age. Little is known about associations of sex and age with methylation of monoamine oxidase A (MAOA). Methylation of the first exonic and partial first intronic region of MAOA has been shown to strengthen associations of interactions of MAOA-uVNTR genotypes and adversity with aggression and substance misuse. Our study examined associations of sex and age with MAOA first exon and intron methylation levels in 252 women and 157 men aged 14-73 years. Participants included adolescents recruited at a substance misuse clinic, their siblings and parents, and healthy women. Women showed ~ 50% higher levels of exonic, and ~ 15% higher intronic, methylation than men. Methylation levels were similar between younger (M = 22.7 years) and older (M = 46.1 years) participants, and stable across age. Age modified few associations of methylation levels with sex. MAOA genotypes modified few associations of methylation with sex and age. Higher methylation levels among women were not explained by genotype, nor interaction of genotype and sexual abuse. Findings were similar after adjusting for lifetime diagnoses of substance dependence (women = 24.3%; men = 34.2%). Methylation levels were higher among women who experienced sexual abuse than women who did not. Results extend on prior studies by showing that women display higher levels of methylation than men within first intronic/exonic regions of MAOA, which did not decrease with age in either sex. Findings were not conditioned by genotype nor interactions of genotype and trauma, and indicate X-chromosome inactivation.

RESUMO

BACKGROUND: Various combinations of childhood conduct problems, callous traits and anxiety may confer increased risk of offending, psychopathic traits and mental disorders. Knowledge of these outcomes in adulthood is limited. AIMS: To compare adult criminal convictions, psychopathy checklist scores and mental disorders between five groups of men, variously defined in childhood by: (1) callous traits, (2) conduct problems, (3) conduct problems and callous traits, (4) conduct problems and callous traits and anxiety or (5) developing typically. METHOD: Teachers rated conduct problems, callous traits and anxiety at ages 6, 10 and 12 years. Criminal convictions from age 12 to 24 were extracted from official records. The Psychopathy Checklist-Revised (PCL-R) and diagnostic interviews were completed at age 33. RESULTS: Relative to the typically developing group, the groups with conduct problems, with and without callous traits and anxiety, showed 5-fold elevations in risks of violent convictions and 3 to 4-fold elevations in risk for antisocial personality disorder, while the groups with conduct problems only and with conduct problems plus callous traits plus anxiety were at increased risk for borderline personality disorder. All risk groups obtained higher PCL-R total scores than the typically developing childhood group. CONCLUSIONS AND IMPLICATIONS: It is widely accepted that childhood conduct problems in boys are associated with increased risks of criminal convictions and poorer mental health, but our findings suggest that teachers can identify different subgroups and these have different trajectories. As some subgroups were small, replication is recommended, but our findings offer preliminary support for trialling specific interventions for at risk boys.

RESUMO

As many as 10.7% of males and 7.5% of females display early-onset, stable, antisocial and aggressive behavior (ESAAB). Most research has focused on males. These individuals are diagnosed with conduct disorder in childhood and antisocial personality disorder in adulthood, and a very few, almost all males, present the syndrome of psychopathy. ESAAB includes three subgroups: (1) conduct problems and callousness; (2) conduct problems, callousness, and anxiety; and (3) conduct problems. Heritability of the first two subtypes is high. This high heritability derives, at least in part, from genes involved in regulating serotonergic functioning early in life and to genotypes that confer sensitivity to trauma. The first subtype is rare and characterized by difficulty in face emotion recognition, especially fear and sadness, and hypoarousal as indexed by both autonomic and neural measures, and by structural brain abnormalities. By contrast, those with conduct problems, callousness, and anxiety are more common. They include a greater proportion of females and show hypersensitivity to threat that triggers reactive aggression and that is reflected in both autonomic and neural functioning. In sum, fewer females than males present ESAAB, but many characteristics, autonomic and neural correlates, and etiology are similar. Importantly, however, females with ESAAB play a critical role in the intergenerational transfer of antisocial behavior. Despite higher prevalence of EASSB in males than females, few sex differences in neural abnormalities have been identified.

RESUMO

BACKGROUND: Individuals with bipolar disorder (BD) often possess maladaptive traits and present with various difficulties in psychosocial functioning. However, little is known about the intimate partners of adults with bipolar disorder (BD) and how mental illnesses other than BD within couples may further complicate the picture. Such knowledge is needed to inform both couple and family interventions. METHODS: Participants were parents whose children were enrolled in a prospective study: 55 with BD and their partners, and 47 healthy control couples. All completed diagnostic interviews, and questionnaires describing personality traits, negative life events, coping skills, social support, marital adjustment and inter-partner verbal aggression. Parents with BD and healthy control parents were compared, as were the intimate partners. A series of exploratory analyses focused on the average measures within couples, with and without BD, and took account of comorbid personality disorders among those with BD and major depressive disorder among their partners. RESULTS: Intimate partners of adults with BD, relative to healthy control partners, presented with more mental disorders, higher neuroticism, lower extraversion, more emotion-focused coping, smaller social networks, less satisfaction with their social networks, and little, satisfying social contact. Additionally, they reported less consensus and satisfaction in their marital relationships, and engaged in more verbal aggression towards their partners. Participants with BD showed similar, more extreme, characteristics. Marital distress and verbal aggression were greatest among couples with an adult having BD and a comorbid personality disorder or a partner with major depressive disorder. CONCLUSION: This study contributes to the literature by demonstrating that both parents with BD and their intimate partners exhibit high levels of mental illness, maladaptive personality traits and psychosocial difficulties, thus limiting their partners' ability to provide support and stability in the these high risk families. Moreover, mental illnesses other than BD may contribute to marital problems within couples. Some statistical analyses, particularly those involving comorbid conditions, were under-powered in this study. As clinical implications, the current study suggests that both individuals with BD and their partners could benefit from interventions aimed at lowering emotionality and verbal aggression, and increasing social support and effective coping skills.

RESUMO

BACKGROUND: The association between childhood maltreatment and subsequent aggressive behaviour is modified by monoamine oxidase A (MAOA) functional polymorphism (MAOA-uVNTR) genotype, MAOA-Long (MAOA-L) in females, MAOA-Short (MAOA-S) in males. Childhood maltreatment is associated with differential DNA methylation in several genes. Consistent with recent proposals, we hypothesized that the association of the interaction of MAOA genotype and maltreatment with aggressive behaviour is further moderated by methylation of a region of interest (ROI) spanning the first exon and partial first intron of MAOA. METHOD: The sample included 117 women and 77 men who completed interviews and questionnaires to report maltreatment and aggressive behaviour towards others and provided saliva samples for DNA extraction. The MAOA-uVNTR polymorphism was genotyped, and methylation of the MAOA ROI was assessed. RESULTS: Following adjustment for substance misuse, psychoactive medication use, and in males tobacco use, the highest levels of aggressive behaviour were found among maltreated male carriers of MAOA-S with high levels of exonic methylation. CONCLUSION: Methylation levels within the MAOA ROI further contributed to the interaction of MAOA risk genotypes and maltreatment on aggressive behaviours among men.

RESUMO

The rank-ordered logit (rologit) model was recently introduced as a robust approach for analysing continuous outcomes, with the linear exposure effect estimated by scaling the rank-based log-odds estimate. Here we extend the application of the rologit model to continuous outcomes with ties and ordinal outcomes treated as imperfectly-observed continuous outcomes. By identifying the functional relationship between survival times and continuous outcomes, we explicitly establish the equivalence between the rologit and Cox models to justify the use of the Breslow, Efron and perturbation methods in the analysis of continuous outcomes with ties. Using simulation, we found all three methods perform well with few ties. Although an increasing extent of ties increased the bias of the log-odds and linear effect estimates and resulted in reduced power, which was somewhat worse when the model was mis-specified, the perturbation method maintained a type I error around 5%, while the Efron method became conservative with heavy ties but outperformed Breslow. In general, the perturbation method had the highest power, followed by the Efron and then the Breslow method. We applied our approach to three real-life datasets, demonstrating a seamless analytical workflow that uses stratification for confounder adjustment in studies of continuous and ordinal outcomes.

RESUMO

OBJECTIVE: Traumatic brain injuries (TBIs) are sustained by approximately 17% of males in the general population, many of whom subsequently present mental disorders, cognitive, and physical problems. Little is known about predictors of TBIs and how to prevent them. The present study aimed to determine whether inattention-hyperactivity and/or all externalizing problems presented by boys at age 10 predict subsequent TBIs to age 34 after taking account of previous TBIs and family social status (FSS). METHOD: 742 Canadian males were followed, prospectively, from age 6 to 34. Diagnoses of TBIs were extracted from health files, parents-reported sociodemographic and family characteristics at participants' age 6, and teachers-rated participants' behaviors at age 10. Separate logistic regression models predicted TBIs sustained from age 11 to 17 and from age 18 to 34. For each age period, two models were computed, one included previous TBIs, inattention-hyperactivity, FSS, and interaction terms, the second included previous TBIs, externalizing problems, FSS, and interaction terms. RESULTS: In models that included inattention-hyperactivity, TBIs sustained from age 11 to 17 were predicted by age 10 inattention-hyperactivity (odds ratio [OR] = 1.46, 1.05 to 2.05) and by TBIs prior to age 11 (OR = 3.50, 1.48 to 8.24); TBIs sustained from age 18 to 34 were predicted by age 10 inattention-hyperactivity (OR = 1.31, 1.01 to 170). In models that included all externalizing problems, TBIs from age 11 to 17 were predicted by prior TBIs (OR = 3.66, 1.51 to 8.39); TBIs sustained from age 18 to 34 were predicted by age 10 externalizing problems (OR = 1.45, 1.12 to 1.86). Neither FSS nor interaction terms predicted TBIs in any of the models. CONCLUSIONS: Among males, using evidence-based treatments to reduce inattention-hyperactivity and externalizing problems among boys could, potentially, decrease the risk of TBIs to age 34. Further, boys who sustain TBIs in childhood require monitoring to prevent recurrence in adolescence.

RESUMO

Among females, conduct disorder (CD) before age 15 is associated with multiple adverse outcomes in adulthood. The few existing structural neuroimaging studies of females with CD report abnormalities of gray matter volumes. The present study compared cortical thickness and surface area of young women with childhood/adolescent CD and healthy women to determine whether cortical abnormalities were present in adulthood and whether they were related to prior CD. Structural brain images from 31 women with CD and 25 healthy women were analyzed using FreeSurfer. Group differences between cortical thickness and surface area were assessed using cluster-wise corrections with Monte Carlo simulations. Women with prior CD, relative to healthy women, showed: (1) reduced cortical thickness in left fusiform gyrus extending up to entorhinal cortex and lingual gyrus; (2) reduced surface area in right superior parietal cortex; (3) increased surface area in left superior temporal gyrus, and right precentral gyrus. These differences remained significant after adjusting for past comorbid disorders, current symptoms of anxiety and depression, current substance use as well as maltreatment. The study suggests that among females, CD prior to age 15 is associated with cortical structure abnormalities in brain regions involved in emotion processing and social interaction.

RESUMO

The importance of Vesicular Glutamate Transporter 2 (VGLUT2)-mediated neurotransmission has been highlighted in studies on addiction-related phenotypes. The single nucleotide polymorphism rs2290045 in VGLUT2 has been associated with alcohol dependence, but it is unknown whether or how this association is affected by environmental factors. The present study determined whether the association of alcohol-related problems with the rs2290045 in the VGLUT2 gene was modified by negative and positive environmental factors. Three samples were included: a clinical sample of 131 adolescents followed from age 17 to 22; a general population sample of 1794 young adults; and a general population sample of 1687 adolescents followed from age 14 to 17. DNA was extracted from saliva and the rs2290045 (T/C) was genotyped. Alcohol-related problems were assessed using the Alcohol Use Disorders Identification Test. Stressful life events (SLE) and parenting were assessed by questionnaires. Gene-environment interactions were investigated using a dual statistical approach. In all samples (effect sizes 0.6-6.2%), and consistent with the differential susceptibility framework, T carriers exposed to SLE reported more alcohol-related problems if they had experienced poor parenting, and lower alcohol-related problems if they had received supportive parenting. T carriers not exposed to SLE reported higher alcohol-related problems if they had received supportive parenting and lower alcohol-related problems if they had received poor parenting. Among CC carriers, alcohol-related problems did not vary as a function of negative and positive environmental factors. In conclusion, in three samples of youths, alcohol-related problems were associated with an interaction of VGLUT2 rs2290045, SLE, and parenting.

RESUMO

OBJECTIVE: The authors aimed to elucidate the links between traumatic brain injuries (TBIs) and criminal convictions in a sample of 724 Canadian males with and without criminal records followed up to age 24. METHODS: Prospectively collected data were analyzed to determine whether prior TBIs predicted subsequent criminal convictions after taking account of family social status (FSS) and childhood disruptive behaviors. At age 24, diagnoses of TBIs were extracted from health records and convictions from official criminal records. In childhood, teachers rated disruptive behaviors and parents reported FSS. RESULTS: Proportionately more individuals with offender status than nonoffender status sustained a TBI from age 18 to age 24 but not before age 18. Individuals with offender status who had sustained a TBI before and after their first conviction were similar in numbers, were raised in families of low social status, and presented high levels of disruptive behaviors from age 6 to age 12. When FSS and childhood disruptive behaviors were included in multivariable regression models, sustaining a prior TBI was not associated with an increased risk of juvenile convictions for any type of crime, for violent crimes, for convictions for any crime or violent crime from age 18 to age 24, or for a first crime or a first violent crime from age 18 to age 24. CONCLUSIONS: Among males, there was no evidence that prior TBIs were associated with an increased risk of subsequent criminal convictions from age 12 to age 24 when taking account of FSS and childhood disruptive behaviors, although these latter factors may be associated with an increased prevalence of TBIs among adult offenders.

RESUMO

PURPOSE: To prevent violence among persons with psychosis, further knowledge of the correlates and risk factors is needed. These risk factors may vary by nation. PATIENTS AND METHODS: This study examined factors associated with violent assaults in 158 patients with psychosis and in a matched control sample of 158 adults without psychosis in the Czech Republic. Participants completed interviews and questionnaires to confirm diagnoses, report on aggressive behavior, current and past victimization, and substance use. Additional information was collected from collateral informants and clinical files. Multiple regression analyses were conducted to identify factors that were independently associated with committing an assault in past 6 months. RESULTS: The presence of a psychotic disorder was associated with an increased risk of assaults (OR =3.80; 95% CI 2.060-7.014). Additional risk factors in persons with and without psychosis included recent physical victimization (OR =7.09; 95% CI 3.922-12.819), childhood maltreatment (OR =3.15; 95% CI 1.877-5.271), the level of drug use (OR =1.13; 95% CI 1.063-1.197), and the level of alcohol use (OR =1.04; 95% CI 1.000-1.084). Increasing age (OR =0.96; 95% CI 0.942-0.978) and employment (OR =0.30; 95% CI 0.166-0.540) were protective factors. Except for drug use, which appeared to have greater effect on violence in the group without psychosis, there were no major differences between patients and controls in these risk and protective factors. To our knowledge, this is the first published comparison of assault predictors between schizophrenia patients and matched controls. CONCLUSION: Recent physical victimization was the strongest predictor of assaults. Our findings are consistent with the emerging empirical evidence pointing to the very important role of victimization in eliciting violent behavior by the victims. Some current prediction instruments may underestimate the risk of violent behavior as they take little account of current victimization. Although psychosis per se elevates the risk of violence, other risk and protective factors for violence in persons with psychosis and comparison group are largely similar.

RESUMO

BACKGROUND: Psychopathic traits vary dimensionally in the population and are associated with multiple negative outcomes. The impaired integration theory (IIT) proposes that psychopathic traits are associated with abnormal neural network topology, such that disturbed integration of neural networks results in a self-perpetuating impairment in rapid integration and learning from multiple components of information. The IIT is based on findings from male offenders presenting high scores on all psychopathic traits. The present study investigated whether IIT predictions of topology abnormalities were associated with psychopathic traits, measured dimensionally, in young adult women with subsyndromal scores. METHODS: Seventy-three women, with an average age of 25 years, were assessed using the Psychopathy Checklist-Revised and completed resting-state magnetic resonance imaging. Preprocessed time series from 90 anatomical regions were extracted to form connectivity matrices and used to calculate network topology based on graph theory. Correlations between total psychopathy and factor scores with both the raw connectivity matrix and global and local graph theory measures were computed. RESULTS: Total psychopathy scores and behavioral factor scores were related to connectivity between several pairs of regions, primarily limbic/paralimbic. Psychopathic traits were not associated with global topology measures. Topology abnormalities, robust across network formation thresholds, were found in nodes of the default mode network and in hubs connecting several resting-state networks. CONCLUSIONS: IIT predictions of abnormal topology of hubs and default mode network nodes with dimensionally measured psychopathic traits were confirmed in a sample of young women. Regional abnormalities, accompanied by preserved global topology, may underlie context-specific abnormal information processing and integration.
