BACKGROUND: Previous studies find that both schizophrenia and mood disorder risk alleles contribute to adult depression and anxiety. Emotional problems (depression or anxiety) begin in childhood and show strong continuities into adult life; this suggests that symptoms are the manifestation of the same underlying liability across different ages. However, other findings suggest that there are developmental differences in the etiology of emotional problems at different ages. To our knowledge, no study has prospectively examined the impact of psychiatric risk alleles on emotional problems at different ages in the same individuals...

BACKGROUND: Oxytocin is a peptide hormone that influences the integration of social cognition with behavior and affect regulation. Oxytocin also prominently directs the transition of neuronal GABA neurotransmission from excitatory to inhibitory after birth. The oxytocin receptor (OXTR) is linked to schizophrenia, a heterogeneous syndrome. Relationships of OXTR polymorphisms with specific clinical features could aid in evaluating any role of oxytocin in the pathogenesis of schizophrenia...

Objective Life expectancy of psychiatric patients is markedly shorter compared to the general population, likely partly due to smoking or misuse of other substances. We investigated prevalence and correlates of substance use among psychiatric patients. Methods Within the Helsinki University Psychiatric Consortium Study, data were collected on substance use (alcohol, smoking, and illicit drugs) among patients with schizophrenia or schizoaffective disorder (n = 113), bipolar (n = 99), or depressive disorder (n = 188)...

OBJECTIVE: Medicaid beneficiaries with severe mental illnesses are a financially disadvantaged group with high rates of smoking and poor cessation outcomes. This study examined whether abstinence-contingent monetary incentives improved outcomes when added to cessation treatments at community mental health centers: prescriber visit for pharmacotherapy only (PV only), prescriber visit and facilitated quitline (PV+Q), and prescriber visit and telephone cognitive-behavioral therapy (PV+CBT)...

Epilepsy is a neurologic condition which often occurs with other neurologic and psychiatric disorders. The relation between epilepsy and these conditions is complex. Some population-based studies have identified a bidirectional relation, whereby not only patients with epilepsy are at increased risk of suffering from some of these neurologic and psychiatric disorders (migraine, stroke, dementia, autism, depression, anxiety disorders, Attention deficit hyperactivity disorder (ADHD), and psychosis), but also patients with these conditions are at increased risk of suffering from epilepsy...

INTRODUCTION: The aim of this study is to determine odds of aggression and associated factors in patients with schizophrenia-spectrum disorders (SSD) and affective disorders who were evaluated in an emergency department setting. METHODS: A retrospective study was conducted using de-identified data from electronic medical records from 3.322 patients who were evaluated at emergency psychiatric settings. Data extracted included demographic information, variables related to aggression towards people or property in the past 6months, and other factors that could potentially impact the risk of aggression, such as comorbid diagnoses, physical abuse and sexual abuse...

AIMS: After the diagnosis of immune-mediated inflammatory diseases (IMID) such as inflammatory bowel disease (IBD), multiple sclerosis (MS) and rheumatoid arthritis (RA), the incidence of psychiatric comorbidity is increased relative to the general population. We aimed to determine whether the incidence of psychiatric disorders is increased in the 5 years before the diagnosis of IMID as compared with the general population. METHODS: Using population-based administrative health data from the Canadian province of Manitoba, we identified all persons with incident IBD, MS and RA between 1989 and 2012, and cohorts from the general population matched 5 : 1 on year of birth, sex and region to each disease cohort...

BACKGROUND: Histidine triad nucleotide-binding protein 1 (HINT1) is regarded as a haplo-insufficient tumor suppressor and is closely associated with diverse neuropsychiatric diseases. Moreover, HINT1 is related to gender-specific acute behavior changes in schizophrenia and in response to nicotine. Stress has a range of molecular effects in emotional disorders, which can cause a reduction in brain-derived neurotrophic factor (BDNF) expression in the hippocampus, resulting in hippocampal atrophy and neuronal cell loss...

INTRODUCTION: People with serious mental illnesses experience excess morbidity and premature mortality resulting from preventable conditions. The goal was to examine disparities in preventive care that might account for poor health outcomes. METHODS: In this retrospective cohort study, adults (N=803,276) served by Kaiser Permanente Northwest and federally qualified health centers/safety-net community health clinics were categorized into five groups: schizophrenia spectrum disorders, bipolar disorders/affective psychoses, anxiety disorders, nonpsychotic unipolar depression, and reference groups with no evidence of these specific mental illnesses...

BACKGROUND: Anhedonia, the diminished ability to experience pleasure, is an important dimensional entity linked to depression, schizophrenia, and other emotional disorders, but its origins and mechanisms are poorly understood. We have previously identified anhedonia, manifest as decreased sucrose preference and social play, in adolescent male rats that experienced chronic early-life adversity/stress (CES). Here we probed the molecular, cellular, and circuit processes underlying CES-induced anhedonia and tested them mechanistically...

Schizophrenia is a neurodevelopmental disorder that affects up to 1% of the general population. Various genes show associations with schizophrenia and a very weak nominal association with the tight junction protein, claudin-5, has previously been identified. Claudin-5 is expressed in endothelial cells forming part of the blood-brain barrier (BBB). Furthermore, schizophrenia occurs in 30% of individuals with 22q11 deletion syndrome (22q11DS), a population who are haploinsufficient for the claudin-5 gene. Here, we show that a variant in the claudin-5 gene is weakly associated with schizophrenia in 22q11DS, leading to 75% less claudin-5 being expressed in endothelial cells...

Occurring in at least 1 in 3,000 live births, chromosome 22q11.2 deletion syndrome (22q11DS) produces a complex phenotype that includes a constellation of medical complications such as congenital cardiac defects, immune deficiency, velopharyngeal dysfunction, and characteristic facial dysmorphic features. There is also an increased incidence of psychiatric diagnosis, especially intellectual disability and ADHD in childhood, lifelong anxiety, and a strikingly high rate of schizophrenia spectrum disorders, which occur in around 30% of adults with 22q11DS...

Complex roles for astrocytes in health and disease continue to emerge, highlighting this class of cells as integral to function and dysfunction of the nervous system. In particular, escalating evidence strongly implicates a range of changes in astrocyte structure and function associated with neuropsychiatric diseases including major depressive disorder, schizophrenia, and addiction. These changes can range from astrocytopathy, degeneration, and loss of function, to astrogliosis and hypertrophy, and can be either adaptive or maladaptive...

BACKGROUND: Patient education is increasingly accessed with online resources and is essential for patient satisfaction and clinical outcomes. The average American adult reads at a seventh grade level, and the National Institute of Health (NIH) and the American Medical Association (AMA) recommend that information be written at a sixth-grade reading level. Health literacy plays an important role in the disease course and outcomes of all patients, including those with depression and likely other psychiatric disorders, although this is an area in need of further study...

INTRODUCTION: Providing comprehensive services for about 400 patients in the South Herefordshire area, the community mental health team manages cases of varying severity and complexity, ranging from Schizophrenia, to neuroses and disorders of adult personality. Antipsychotic medication remains a mainstay of treatment and management for patients under the team case load; hence a need exists for a detailed look into the prescription patterns of such medications. AIM: The aim of this study was to look into the prescribing patterns of antipsychotics for a sample of 50 patients in the South Herefordshire community team during the year of 2016 (from Jan 2016 to Dec 2016), as well as investigate whether these antipsychotics were licensed to be used for the corresponding diagnoses of these patients...

Antipsychotics are a key intervention strategy in pharmacotherapy of schizophrenia. However, benzodiazepines are often prescribed to control sleep disturbances, anxiety or behavioural disinhibition. There is clinical evidence for the beneficial effect of the combined treatment of antipsychotics and benzodiazepines resulting in more favorable treatment outcome in schizophrenia with regard to positive and negative symptoms. This clinical phenomenon seems to be associated with the GABA-ergic activit ythat is believed to be disrupted in the schizophrenia and direct benzodiazepines effect on GABA-A receptors...

Patients with mental disorders are subject to a greater number of risk factors for oral and dental disease than the general population. This is mostly caused by the side effects of the medications that they receive, lack of self-care, difficulty to access health services, a negative attitude towards healthcare providers, and patients’ lack of cooperation in dental treatments. The most common psychiatric disorders in our population are depression, anxiety disorders, schizophrenia, bipolar disorder, and dementia...

BACKGROUND: To date, a diagnosis in psychiatry is largely based on a clinical interview and questionnaires. The retrospective and subjective nature of these methods leads to recall and interviewer biases. Therefore, there is a clear need for more objective and standardized assessment methods to support the diagnostic process. The introduction of virtual reality (VR) creates the possibility to simultaneously provoke and measure psychiatric symptoms. Therefore, VR could contribute to the objectivity and reliability in the assessment of psychiatric disorders...

INTRODUCTION: Anxiety is frequent in patients with schizophrenia and poses a major impact on patients perceived quality of life, daily functioning and risk of suicide. Pregabalin has shown effective in the treatment of generalized anxiety disorder and has been suggested for the treatment of anxiety in patients with schizophrenia. As evidence is sparse regarding treatment of anxiety in this patient group, we aimed to investigate the use of pregabalin for anxiety in patients with schizophrenia...

The circadian clock system drives daily rhythms in physiology, metabolism, and behavior in mammals. Molecular mechanisms of this system consist of multiple clock genes, with Circadian Locomotor Output Cycles Kaput (CLOCK) as a core member that plays an important role in a wide range of behaviors. Alterations in the CLOCK gene are associated with common psychiatric disorders as well as with circadian disturbances comorbidities. This review addresses animal, molecular, and genetic studies evaluating the role of the CLOCK gene on many psychiatric conditions, namely autism spectrum disorder, schizophrenia, attention-deficit/hyperactivity disorder, major depressive disorder, bipolar disorder, anxiety disorder, and substance use disorder...
