Brain-themed self-help and the healthcare provider in the United States.

People commonly use the Internet to search for health information and tend to use the information they find without regard to source or credibility. Although regulation plays some role in minimizing false claims made by manufacturers of self-help products, effective communication with health professionals likely offers greater protection to the patient or consumer accessing self-help materials. In order to best serve patients (or healthcare consumers), providers should educate them about their healthcare needs, inquire about self-help product use, understand appropriate use, discuss the risks and benefits of use, monitor the patients' condition during use, and document these conversations. Although some people fear that patient use of brain-themed self-help will undermine the doctor-patient relationship, it is more likely to open another avenue of communication if providers are knowledgeable about self-help products. Given the rise in importance of the Internet as a source of information for people, opting out of these discussions is realistically not an option.

Regulating mobile mental health apps.

Mobile medical apps (MMAs) are a fast-growing category of software typically installed on personal smartphones and wearable devices. A subset of MMAs are aimed at helping consumers identify mental states and/or mental illnesses. Although this is a fledgling domain, there are already enough extant mental health MMAs both to suggest a typology and to detail some of the regulatory issues they pose. As to the former, the current generation of apps includes those that facilitate self-assessment or self-help, connect patients with online support groups, connect patients with therapists, or predict mental health issues. Regulatory concerns with these apps include their quality, safety, and data protection. Unfortunately, the regulatory frameworks that apply have failed to provide coherent risk-assessment models. As a result, prudent providers will need to progress with caution when it comes to recommending apps to patients or relying on app-generated data to guide treatment.

Behavioral Genetics and the Forensic Mental Health Provider: An Overview.

The area of behavioral genetics has sufficiently entered the area of forensic mental health work that providers should have some working knowledge of the strengths and limitations of these exciting technical advances. Using MAOA as an example, this essay reviews some of the recurring themes in forensic behavioral genetics and suggests additional ways in which the technology might be used in legal matters.

Smoking, Methylation at AHRR, and Recidivism Risk in a Community Correction Sample of Individuals at High Risk for Recidivism.

Individuals supervised by community correction programs have a high rate of tobacco use and high frequency of tobacco dependence. As compared with supervisees without tobacco dependence, probationers and parolees with tobacco dependence were more likely to abuse other substances and report poorer health. In this sample of 374 predominantly felon and repeat offenders, at high risk for recidivism, over 95% of subjects smoked or used other tobacco products, 87% were actively smoking at the time of interview, and 70% met criteria for lifetime tobacco dependence. Seventy-four percent had DNA demethylation, defined as methylation less than 83%, at the aryl hydrocarbon receptor repressor (AHRR) residue interrogated by cg0557592 at the time of interview. Seventy-eight percent exhibited four-year recidivism. Demethylation was associated with four-year recidivism in women, but not men. These findings suggest that methylation at cg05575921 serves as a semi-quantitative measure of both recent use and lifetime burden, that community correction populations continue to smoke at high risk, that measurement of methylation may add to the identification of female offenders at risk for recidivism, and that treatments to assist in cessation efforts are desperately needed.

Early phase psychosis and criminal conviction in United States adults.

AIM: Individuals experiencing early phase psychosis (EPP) are at increased risk for legal involvement. In prior studies, between 14% and 75% of individuals with EPP reported a history of criminal offending behaviour, criminal charges, or criminal convictions. To better understand the frequency of criminal conviction in a specialty treatment clinic serving EPP clients, the research team supplemented self-reported data from the clinic intake with information from publicly available databases. METHODS: In this sample of 309 adults, approximately one quarter of patients (n = 76) self-reported a history of arrest, incarceration, probation, or parole within 6 months of enrolment in a treatment clinic. The research team expanded upon this and collected data from a public database of court proceedings in Indiana for all clinic participants before and after enrolment. RESULTS: Thirty-nine percent (n = 122) had three or more traffic tickets or a conviction for an ordinance violation, misdemeanour, or felony in the state of Indiana as an adult. This is over two times the national average. Drug and alcohol related convictions were the most common single conviction type, and 29% (n = 89) of subjects experienced at least one incarceration. CONCLUSIONS: These data highlight the need for specialty clinics to partner with professionals with expertise in the prevention and management of criminal behaviour. Future studies should examine risk factors for individuals experiencing EPP and criminal conviction.

Relative contributions of gender and traumatic life experience to the prediction of mental disorders in a sample of incarcerated offenders.

The objective of this study was to quantify the relative contributions of gender and traumatic life experience to psychiatric disorders in a sample of 320 offenders entering a state prison. Women were more likely than men to report traumatic events and personal and family mental health treatment histories; and were more likely to meet criteria for posttraumatic stress, borderline personality, and eating disorders. People reporting traumatic life experiences were more likely than those not so reporting to have family mental histories and to meet criteria for mood, anxiety, psychotic, antisocial personality, and borderline personality disorders, as well as elevated suicide risk. With both gender and trauma included in the logistic regression models, only trauma was a significant predictor of mood, anxiety, psychotic, attention deficit hyperactivity, and antisocial personality disorders, as well as suicide risk. Trauma-informed programming, regardless of gender, is important for incarcerated offenders. To the extent that trauma is also criminogenic, these data suggest that women and men share the risk.

Methylation at 5HTT mediates the impact of child sex abuse on women's antisocial behavior: an examination of the Iowa adoptee sample.

OBJECTIVE: To examine epigenetic processes linking childhood sex abuse to symptoms of antisocial personality disorder (ASPD) in adulthood and to investigate the possibility that the link between childhood sex abuse and deoxyribonucleic acid methylation at the 5HTT promoter might represent a pathway of long-term impact on symptoms of ASPD. METHOD: Deoxyribonucleic acid was prepared from lymphoblast cell lines derived from 155 female participants in the latest wave of the Iowa Adoptee Study. Methylation at 71 CpG residues was determined by quantitative mass spectroscopy, and the resulting values were averaged to produce an average CpG ratio for each participant. Simple associations and path analyses within an Mplus framework were examined to characterize the relationships among childhood sex abuse, overall level of methylation among women, and subsequent antisocial behavior in adulthood. Direct effects of biological parent psychopathology and 5HTT genotype were controlled. RESULTS: Replicating prior work, we found that a significant effect of childhood sex abuse on methylation of the 5HTT promoter region emerged for women. In addition, a significant effect of methylation at 5HTT on symptoms of ASPD emerged. CONCLUSIONS: Child sex abuse may create long-lasting changes in methylation of the promoter region of 5HTT in women. Furthermore, hypermethylation may be one mechanism linking childhood sex abuse to changes in risk for adult antisocial behavior in women. Better understanding of the methylome may prove critical in understanding the role of childhood environments on long-term psychiatric sequelae.

The relationship of deiodinase 1 genotype and thyroid function to lifetime history of major depression in three independent populations.

Major depression (MD) is often associated with disturbances of the hypothalamic/pituitary/thyroid (HPT) axis. Unfortunately, whether this association is secondary to common underlying genetic variation or whether the MD-associated disturbances in HPT function are chronic or state-dependent is unknown. To examine these questions, we genotyped 12 single nucleotide polymorphisms identified in previous genome wide association analyses of thyroid function in DNA contributed by 1,555 subjects from three longitudinal ethnically diverse studies that are well-characterized for lifetime MD and thyroid function. We then examined associations between genetic variants and key outcomes of thyroid stimulating hormone, free thyroxine (FT4) and depression. We confirmed prior findings that two variants in deiodinase 1 (DIO1), including a variant in the 3'UTR of DIO1 (rs11206244), were associated with altered FT4 levels in both White and African American subjects. We also found that rs11206244 genotype was associated with lifetime MD in White female subjects, in particular those from high-risk cohorts. However, we found no association of current FT4 levels with lifetime MD in either ethnic group. We conclude that genetic variation influencing thyroid function is a risk factor for MD. Given the evidence from prior studies, further investigations of role of HPT variation in etiology and treatment of MD are indicated.

Antisocial personality disorder in incarcerated offenders: Psychiatric comorbidity and quality of life.

BACKGROUND: We determined the frequency of antisocial personality disorder (ASPD) in offenders. We examined demographic characteristics, psychiatric comorbidity, and quality of life in those with and without ASPD. We also looked at the subset with attention-deficit/hyperactivity disorder (ADHD). METHODS: A random sample of 320 newly incarcerated offenders was assessed using the Mini International Neuropsychiatric Interview (MINI), the 36-item Short Form Health Survey (SF-36), and the Level of Service Inventory-Revised (LSI-R). RESULTS: ASPD was present in 113 subjects (35.3%). There was no gender-based prevalence difference. Offenders with ASPD were younger, had a higher suicide risk, and had higher rates of mood, anxiety, substance use, psychotic, somatoform disorders, borderline personality disorder, and ADHD. Quality of life was worse, and their LSI-R scores were higher, indicating a greater risk for recidivism. A subanalysis showed that offenders with ASPD who also had ADHD had a higher suicide risk, higher rates of comorbid disorders, and worse mental health functioning. CONCLUSION: ASPD is relatively common among both male and female inmates and is associated with comorbid disorders, high suicide risk, and impaired quality of life. Those with comorbid ADHD were more impaired than those without ADHD. ASPD occurs frequently in prison populations and is nearly as common in women as in men. These study findings should contribute to discussions of appropriate and innovative treatment of ASPD in correctional settings.

Behavioral genetics in antisocial spectrum disorders and psychopathy: a review of the recent literature.

Behavioral geneticists are increasingly using the tools of molecular genetics to extend upon discoveries from twin, family, and adoption studies concerning the heritability of antisocial spectrum disorders and psychopathy. While there is a substantial body of research concerning antisocial spectrum disorders in the behavioral genetics literature, only a few studies could be located using the phenotype of psychopathy. In this report we summarize some of the recent molecular genetics work concerning antisocial spectrum disorders and psychopathy, with a focus on genes involved in the serotonergic and dopaminergic pathways, while also mentioning some of the novel genetic factors being considered. Monoamine oxidase (MAOA) and the serotonin transporter (5HTT) are reviewed at length, as these genes have received significant scientific attention in recent years and are sites of high biological plausibility in antisocial spectrum disorders and psychopathy.

The effect of smoking on MAOA promoter methylation in DNA prepared from lymphoblasts and whole blood.

Prior work using lymphoblast DNA prepared from 192 subjects from the Iowa Adoption Studies (IAS) demonstrated that decreased MAOA promoter methylation was associated with lifetime symptom count for nicotine dependence (ND) and provided suggestive evidence that the amount of methylation is genotype dependent. In the current investigation, we replicate and extend these prior findings in three ways using another 289 IAS subjects and the same methodologies. First, we show that methylation is dependent on current smoking status. Second, we introduce a factor analytic approach to DNA methylation, highlighting three distinct regions of the promoter that may function in somewhat different ways for males and females. Third, we directly compare the methylation signatures in DNA prepared from whole blood and lymphoblasts from a subset of these subjects and provide suggestive evidence favoring the use of lymphoblast DNA. We conclude that smoking reliably decreases MAOA methylation, but exact characterization of effects on level of methylation depend on genotype, smoking history, current smoking status, gender, and region of the promoter-associated CpG Island examined.

Examination of the nicotine dependence (NICSNP) consortium findings in the Iowa adoption studies population.

INTRODUCTION: Nicotine dependence results from a complex interplay of genetic and environmental factors. Over the past several years, a large number of studies have been performed to identify distinct gene loci containing genetic vulnerability to nicotine dependence. Two of the most prominent studies were conducted by the Collaborative Study of the Genetics of Nicotine Dependence (NICSNP) Consortium using both candidate gene and high-density association approaches. METHODS: We attempted to confirm and extend the most significant findings from the high-density association study and the candidate gene study using the behavioral and genetic resources of the Iowa Adoption Studies, the largest case-control adoption study of substance use in the United States. RESULTS: We found evidence that genetic variation at CHRNA1, CHRNA2, CHRNA7, and CHRNB1 alters susceptibility to nicotine dependence, but we did not replicate any of the most significant single nucleotide polymorphism associations from the NICSNP high-density association study. DISCUSSION: Further examination of the NICSNP findings in other population samples is indicated.

Medical and psychiatric problems among men and women in a community corrections residential setting.

Though the medical and mental health morbidity of incarcerated offenders has been discussed in a number of recent reports, very few data have been published concerning medical and mental health problems facing those on community corrections supervision. In this study of community corrections offenders utilizing residential facilities, we found that frequencies of substance use disorders, other mental health disorders, and medical problems exceeded frequencies found in the community and, in some cases, were higher than frequencies found in incarcerated individuals. Of particular concern were the high frequencies of substance use disorders, traumatic brain injury, anxiety states, suicidal ideation, and prior self-harm. While the level of self-reported medical and mental health service utilization was higher than expected, it appeared low relative to the disease burden reported by this special population. We conclude that concurrent evaluation and treatment of medical and psychiatric problems during the process of community supervision is indicated in this population.

Frequency of mental and addictive disorders among 320 men and women entering the Iowa prison system: use of the MINI-Plus.

The Mini-International Neuropsychiatric Interview-Plus (MINI-Plus) was used to assess the frequency of mental and addictive disorders among 320 randomly selected men and women newly committed to the general population of the Iowa prison system. More than 90 percent of offenders met criteria for a current or lifetime psychiatric disorder. The most frequent were substance use disorders (90%), mood disorders (54%), psychotic disorders (35%), antisocial personality disorder (35%), and attention deficit hyperactivity disorder (22%). Offenders had a mean of 4.2 MINI-Plus disorders, and two-thirds had 3 or more disorders. Contrary to expectation, there were few gender-based differences. Thirty percent of the offenders were rated at risk for suicide. We conclude that mental and addictive disorders are common among incarcerated offenders and that these individuals are at risk for suicidal behavior.

The relationship of 5HTT (SLC6A4) methylation and genotype on mRNA expression and liability to major depression and alcohol dependence in subjects from the Iowa Adoption Studies.

Serotonin Transporter (5HTT or SLC6A4) mRNA transcription is regulated by both genetic and epigenetic mechanisms. Unfortunately, despite intense scrutiny, the exact identity and contribution of each of these regulatory mechanisms, and their relationship to behavioral illness remain unknown. This lack of knowledge is critical because alterations in SLC6A4 function are posited to be central to a wide variety of CNS disorders. In order to address this shortcoming, we quantified 5HTTLPR genotype, SLC6A4 mRNA production and CpG methylation using biomaterial from 192 lymphoblast cell lines derived from subjects who participated in the latest wave of the Iowa Adoption Studies. We then analyzed the resulting data with respect to clinical characteristics. We confirmed prior findings that the short (s) 5HTTLPR allele is associated with lower amounts of mRNA transcription, but there was no significant effect of the "Long G" allele on mRNA transcription. We also found that CpG methylation was higher (P < 0.0008) and mRNA production (P < 0.0001) was lower in females as compared to males. Those subjects with a lifetime history of Alcohol Dependence had higher levels of SLC6A4 mRNA. There was a trend for an association of increased overall methylation with lifetime history of major depression. Finally, we confirm our prior findings that the exact levels of 5HTT mRNA expression are dependent on how it is measured. We conclude that both genetic variation and epigenetic modifications contribute to the regulation of SLC6A4 function and that more in-depth studies of the molecular mechanisms controlling gene activity and the relationship of these mechanisms to behavioral illness are indicated.

MAOA methylation is associated with nicotine and alcohol dependence in women.

In recent years, the role of epigenetic phenomenon, such as methylation, in mediating vulnerability to behavioral illness has become increasingly appreciated. One prominent locus at which epigenetic phenomena are thought to be in play is the monoamine oxidase A (MAOA) locus. In order to examine the role of methylation at this locus, we performed quantitative methylation analysis across the promoter region of this gene in lymphoblast lines derived from 191 subjects participating in the Iowa Adoption Studies (IAS). We analyzed the resulting data with respect to genotype and lifetime symptom counts for the more common major behavioral disorders in the IAS, antisocial personality disorder (ASPD), and substance use disorders (alcohol (AD) and nicotine dependence (ND)). We found that methylation status was significantly associated with lifetime symptom counts for ND (P < 0.001) and AD (P < 0.008) in women, but not men. Furthermore, a trend was found for women homozygous for the 3,3 allele to have a higher degree of overall methylation than women homozygous for the 4,4 allele (P < 0.10). We conclude that methylation of MAOA may play a significant role in common psychiatric illness and that further examination of epigenetic processes at this locus is in order.

No association of the C677T methylenetetrahydrofolate reductase polymorphism with schizophrenia.

Some serological and genetic studies have suggested that alterations in folate metabolism are associated with increased vulnerability to schizophrenia. In particular, these findings are most striking for the role of a putatively functional variant (C677T) in the methylenetetrahydrofolate reductase (MTHFR) gene. To test the hypothesis that the T allele and the TT genotype are risk factors for psychosis, we genotyped the C677T polymorphism in 206 participants with schizophrenia or schizoaffective disorder and 359 participants from a population control sample. Neither the T allele nor the TT genotype was associated with increased risk for schizophrenia. These results do not support a role for the C677T MTHFR variant in schizophrenia.

Shared psychotic disorder and criminal responsibility: a review and case report of folie à trois.

We present a case of shared psychotic disorder involving three sisters who were successful in establishing an insanity defense on numerous felony charges in the South Carolina criminal court system. Two of the authors of this article were court-appointed examiners in this case. We then present a history of shared psychotic disorder, an overview of the use of this diagnosis in the defense of insanity, and a discussion of the disposition of individuals with "temporary insanity." Finally, we compare shared psychotic disorder, culturally based belief systems, and religious cults, with a focus on their common and contrasting characteristics.
