Autism spectrum disorders (ASDs) and autistic traits in the general population may share genetic susceptibility factors. In this study, we investigated such potential overlap based on common genetic variants. We developed and validated a self-report questionnaire of autistic traits in adults. We then conducted genome-wide association studies (GWASs) of six trait scores derived from the questionnaire through exploratory factor analysis in 1981 adults from the general population. Using the results from the Psychiatric Genomics Consortium GWAS of ASDs, we observed genetic sharing between ASDs and the autistic traits 'childhood behavior', 'rigidity' and 'attention to detail'...

In the adult mammalian brain, newborn granule cells are continuously integrated into hippocampal circuits, and the fine-tuning of this process is important for hippocampal function. Thus, the identification of factors that control adult neural stem cells (NSCs) maintenance, differentiation and integration is essential. Here we show that the deletion of the iron trafficking protein lipocalin-2 (LCN2) induces deficits in NSCs proliferation and commitment, with impact on the hippocampal-dependent contextual fear discriminative task...

Alcohol consumption is a complex trait determined by both genetic and environmental factors, and is correlated with the risk of alcohol use disorders. Although a small number of genetic loci have been reported to be associated with variation in alcohol consumption, genetic factors are estimated to explain about half of the variance in alcohol consumption, suggesting that additional loci remain to be discovered. We conducted a genome-wide association study (GWAS) of alcohol consumption in the large Genetic Epidemiology Research in Adult Health and Aging (GERA) cohort, in four race/ethnicity groups: non-Hispanic whites, Hispanic/Latinos, East Asians and African Americans...

Since the late 1980s the psychoactive drug 3,4-methylenedioxymethamphetamine (MDMA) has had a well-known history as the recreationally used drug ecstasy. What is less well known by the public is that MDMA started its life as a therapeutic agent and that in recent years an increasing amount of clinical research has been undertaken to revisit the drug's medical potential. MDMA has unique pharmacological properties that translate well to its proposed agent to assist trauma-focused psychotherapy. Psychological trauma-especially that which arises early in life from child abuse-underpins many chronic adult mental disorders, including addictions...

OBJECTIVE: Coronary artery disease (CAD) is frequently accompanied by white matter hyperintensities and executive dysfunction. Because acetylcholine is important in executive function, these symptoms may be exacerbated by subcortical hyperintensities (SH) located in cholinergic (CH) tracts. This study investigated the effects of SH on cognitive changes in CAD patients undergoing a 48-week cardiac rehabilitation program. METHODS: Fifty patients (age 66.5 ± 7.1 years, 84% male) underwent the National Institute of Neurological Disorders and Stroke - Canadian Stroke Network neurocognitive battery at baseline and 48 weeks...

BACKGROUND: Suicide is a major public health issue, and a priority requirement is accurately identifying high-risk individuals. The SAD PERSONS suicide risk assessment scale is widely implemented in clinical settings despite limited supporting evidence. This article aims to determine the ability of the SAD PERSONS scale (SPS) to predict future suicide in the emergency department. METHODS: Five thousand four hundred sixty-two consecutive adults were seen by psychiatry consultation teams in two tertiary emergency departments with linkage to population-based administrative data to determine suicide deaths within 6 months, 1, and 5 years...

Despite decades of research, the pathophysiology of bipolar disorder (BD) is still not well understood. Structural brain differences have been associated with BD, but results from neuroimaging studies have been inconsistent. To address this, we performed the largest study to date of cortical gray matter thickness and surface area measures from brain magnetic resonance imaging scans of 6503 individuals including 1837 unrelated adults with BD and 2582 unrelated healthy controls for group differences while also examining the effects of commonly prescribed medications, age of illness onset, history of psychosis, mood state, age and sex differences on cortical regions...

Experimental studies have demonstrated that methylphenidate (MPH) modulates the synaptic vesicle trafficking and synaptotagmin-1 (SytI) mRNA levels. SytI is a regulatory protein of the SNARE complex, a neurotransmitter exocytosis mediator. Despite this evidence, most SNARE complex-related genes have never been evaluated in attention-deficit/hyperactivity disorder (ADHD) pharmacogenetics. This study evaluates, for we believe the first time, polymorphisms on the SNARE complex-related genes STX1A (rs2228607), VAMP2 (26bp Ins/Del) and SYT1 (rs1880867 and rs2251214) on the response to immediate-release methylphenidate (IR-MPH) in a naturalistic sample of adults with ADHD...

OBJECTIVES: Tobacco use is undertreated in individuals with psychiatric and substance use disorders (SUDs), with concerns that quitting smoking may compromise recovery. We evaluated outcomes of a tobacco intervention among psychiatric patients with co-occurring SUDs. METHODS: Data from 2 randomized tobacco treatment trials conducted in inpatient psychiatry were combined; analyses focused on the subsample with co-occurring SUDs (n = 216). Usual care provided brief advice to quit and nicotine replacement therapy during the smoke-free hospitalization...

Fabry disease (FD) is a genetic X-linked, multisystemic, progressive lysosomal storage disorder (LSD). Depression has emerged as a disease complication, with prevalence estimates ranging from 15 to 62%. This is a pilot study examining the effects of psychological counseling for depression in FD on depression, adaptive functioning (AF), quality of life (QOL), and subjective pain experience. Telecounseling was also piloted, as it has beneficial effects in other chronic diseases which make in-person counseling problematic...

BACKGROUND: In the United States, people with limited English proficiency (LEP) receive poorer medical care than those proficient in English. Few studies demonstrate how linguistic barriers complicate psychiatric care; in consultation-liaison (C-L) psychiatry, there are no published data about care disparities for patients with LEP or for whom English is not the preferred language (PL). OBJECTIVE: We sought to determine if PL affects the psychiatric consultation rate...

BACKGROUND: Chronic alcohol intake impacts skin directly, through organ dysfunction or by modifying preexisting dermatoses. However, dermatoses afflicting chronic alcoholics figure in a few studies only. AIM: This study aims to correlate the spectrum of dermatoses in chronic alcoholics with the quantum/duration of alcohol intake and raised liver transaminases. MATERIALS AND METHODS: Adult males, totaling 196, ascertained to fulfill the Royal College of Psychiatry criteria for chronic alcoholism by the de-addiction center and referred for dermatological consult were enrolled as cases, and similar number of age-/sex-matched teetotallers, as controls...

Neurotrophic factors, particularly brain-derived neurotrophic factor (BDNF) and other members of the neurotrophin family, are central mediators of the activity-dependent plasticity through which environmental experiences, such as sensory information are translated into the structure and function of neuronal networks. Synthesis, release and action of BDNF is regulated by neuronal activity and BDNF in turn leads to trophic effects such as formation, stabilization and potentiation of synapses through its high-affinity TrkB receptors...

In many societies, the majority of adults regularly consume alcohol. However, only a small proportion develops alcohol addiction. Individuals at risk often show a high sensation-seeking/low-anxiety behavioural phenotype. Here we asked which role EF hand domain containing 2 (EFhd2; Swiprosin-1) plays in the control of alcohol addiction-associated behaviours. EFhd2 knockout (KO) mice drink more alcohol than controls and spontaneously escalate their consumption. This coincided with a sensation-seeking and low-anxiety phenotype...

BACKGROUND: Schematherapy (ST) is an effective therapy for personality disorders (PD's) in adults, however, empirical research into ST in older adults is limited. The manifestation of schemas over the life course is unclear. Besides, long-term patterns of schemas in old age and whether schemas change during the aging process remain unknown. METHODS: We performed a Delphi study involving a group meeting of nine experts in the field of ST in older adults. RESULTS: Full consensus was achieved that schemas vary later in life, and that this is due to biopsychosocial factors...

The female bias in eating disorder prevalence is the largest in all of psychiatry. Binge eating on palatable food (PF) is a core, maladaptive symptom that cuts across all major types of eating disorders and can be studied via animal models. Using an individual differences rat model of binge eating that identifies binge eating prone (BEP) and binge eating resistant (BER) phenotypes, we previously showed that, compared with males, females consume more PF and are more likely to be classified as BEP. One potential explanation for this sex difference is that PF is inherently more rewarding to females, leading to higher rates of binge eating...
