A key tenet of modern psychiatry is that psychiatric disorders arise from abnormalities in brain circuits that support human behavior. Our ability to examine hypotheses around circuit-level abnormalities in psychiatric disorders has been made possible by advances in human neuroimaging technologies. These advances have provided the basis for recent efforts to develop a more complex understanding of the function of brain circuits in health and of their relationship to behavior-providing, in turn, a foundation for our understanding of how disruptions in such circuits contribute to the development of psychiatric disorders...

Suicide remains a clear, present and increasing public health problem, despite being a potentially preventable tragedy. Its incidence is particularly high in people with overt or un(der)diagnosed psychiatric disorders. Objective and precise identification of individuals at risk, ways of monitoring response to treatments and novel preventive therapeutics need to be discovered, employed and widely deployed. We sought to investigate whether blood gene expression biomarkers for suicide (that is, a 'liquid biopsy' approach) can be identified that are more universal in nature, working across psychiatric diagnoses and genders, using larger cohorts than in previous studies...

BACKGROUND: The concepts of impulsivity and compulsivity are commonly used in psychiatry. Little is known about whether different manifest measures of impulsivity and compulsivity (behavior, personality, and cognition) map onto underlying latent traits; and if so, their inter-relationship. METHODS: A total of 576 adults were recruited using media advertisements. Psychopathological, personality, and cognitive measures of impulsivity and compulsivity were completed...

Patients who present to the emergency department (ED) with mental illness or behavioral complaints merit workup for underlying physical conditions that can trigger, mimic, or worsen psychiatric symptoms. However, there are wide variations in quality of care for these individuals. Psychiatry and emergency medicine specialty guidelines support a tailored, customized approach to patients. Our group has long advocated a dynamic comanagement approach for medical clearance in the ED, and this article summarizes best-practice approaches to the medical clearance of patients with psychiatric illness, tips on history taking, system reviews, clinical/physical examination, and common pitfalls in the medical clearance process...

INTRODUCTION: Despite growing legal control, a wide range of synthetic cannabis analogues is currently used for recreational purposes, notwithstanding their well adverse outcomes, which appear to be more frequent and more serious than those associated with cannabis use. We present the case report of a patient with paranoid schizophrenia, who attempted suicide by serious bodily harm after a single use of "Shiva Ultra Strong," a compound of several synthetic cannabis analogues. CASE SUMMARY: A 32-year-old male patient with paranoid schizophrenia was brought to the emergency department presenting with a severe self-inflicted wound to the neck which lacerated the right jugular vein and ipsilateral airway, and narrowly missed the carotid bifurcation...

Background Faced with one of the lowest physician-to-population ratios in the world, the Government of Tanzania is urging its medical schools to train more physicians. The annual number of medical students admitted across the country rose from 55 in the 1990s to 1,680 approved places for the 2015/16 academic year. These escalating numbers strain existing faculty. Objective To describe the availability of faculty in medical schools in Tanzania. Design We identified faculty lists published on the Internet by five Tanzanian medical schools for the 2011/12 academic year and analyzed the appointment status, rank, discipline, and qualifications of faculty members...

AIMS AND OBJECTIVES: Individuals with severe mental illness (SMI), experience increased mortality-20 years greater disparity for men and 15 years greater disparity for women-compared to the general population (Thornicroft G. Physical health disparities and mental illness: The scandal of premature mortality. Br J Psychiatr. 2011;199:441-442). Numerous factors contribute to premature mortality in persons with SMI, including suicide and accidental death (Richardson RC, Faulkner G, McDevitt J, Skrinar GS, Hutchinson D, Piette JD...

Stress, a prevalent experience in modern society, is a major risk factor for many psychiatric disorders. Although sensorimotor abnormalities are often present in these disorders, little is known about how stress affects the sensory cortex. Combining behavioral analyses with in vivo synaptic imaging, we show that stressful experiences lead to progressive, clustered loss of dendritic spines along the apical dendrites of layer (L) 5 pyramidal neurons (PNs) in the mouse barrel cortex, and such spine loss closely associates with deteriorated performance in a whisker-dependent texture discrimination task...

Rare copy number variants contribute significantly to the risk for schizophrenia, with the 22q11.2 locus consistently implicated. Individuals with the 22q11.2 deletion syndrome (22q11DS) have an estimated 25-fold increased risk for schizophrenia spectrum disorders, compared to individuals in the general population. The International 22q11DS Brain Behavior Consortium is examining this highly informative neurogenetic syndrome phenotypically and genomically. Here we detail the procedures of the effort to characterize the neuropsychiatric and neurobehavioral phenotypes associated with 22q11DS, focusing on schizophrenia and subthreshold expression of psychosis...

Serotonin (5-HT) neurons project from the raphe nuclei throughout the brain where they act to maintain homeostasis. Here, we study 5-HT inputs into the bed nucleus of the stria terminalis (BNST), a major subdivision of the extended amygdala that has been proposed to regulate responses to anxiogenic environments in humans and rodents. While the dorsal part of the BNST (dBNST) receives dense 5-HT innervation, whether and how 5-HT in the dBNST normally modulates anxiety remains unclear. Using optogenetics, we demonstrate that activation of 5-HT terminals in the dBNST reduces anxiety in a highly anxiogenic environment...

Pedophilia is defined as a persistent or dominating sexual preference for prepubescent children characterized by persistent thoughts, fantasies, urges, sexual arousal and behavior. Less than 50% of all child abusers fulfill the diagnostic criteria and an even smaller part exclusively has a preference for children. Following psychiatric classification systems, pedophilia must be distinguished from child sexual abuse. Outpatient treatment and treatment in forensic psychiatry clinics, sociotherapeutic facilities and in correction facilities are different aspects of prevention...

Molecular neuroimaging with PET is an integrated tool in psychiatry research and drug-development for as long as this modality has been available, in particular for studying neurotransmission and endogenous neurotransmitter release. Pharmacologic probes but also behavioral challenges are currently applied to induce changes in neurochemical levels that can be inferred through their effects on changes in receptor binding and related outcome measures. Based on the availability of tracers that are sensitive for measuring neurotransmitter release these experiments have focused on the brain's dopamine system, while recent developments have extended those studies to other targets such as the serotonin or choline system...

INTRODUCTION: Cognitive functions have significant influence on psycho-social and general wellbeing. The quality, content and processing of negative thoughts initiate depressive symptoms; i.e. low mood, decreased self-worth and diminished interest in pleasurable activities. The study assessed the automatic thoughts of patients having depressive illness and evaluated and compared the changes after therapy; i.e. Psychotherapy and pharmacotherapy. METHODS: Diagnosed cases of depressive illness (n=135), according to ICD-10 and study criteria, attending the out-patient clinic of Department of Psychiatry and Mental Health, Tribhuvan University Teaching Hospital, were included...

Social neuroscience, the study of the neurobiological basis of social behavior, has become a major area of current research in behavioral neuroscience and psychiatry, since many psychiatric disorders are characterized by social deficits. Social behavior refers to the behavioral response with regard to socially relevant information, and requires the perception and integration of social cues through a complex cognition process (i.e. social cognition) that involves attention, memory, motivation and emotion. Neurobiological and molecular mechanisms underlying social behavior are highly conserved across species, and inter- and intra-specific variability observed in social behavior can be explained to large extent by differential activity of this conserved neural network...

Benzodiazepines can ameliorate social disturbances and increase social competition, particularly in high-anxious individuals. However, the neural circuits and mechanisms underlying benzodiazepines' effects in social competition are not understood. Converging evidence points to the mesolimbic system as a potential site of action for at least some benzodiazepine-mediated effects. Furthermore, mitochondrial function in the nucleus accumbens (NAc) has been causally implicated in the link between anxiety and social competitiveness...

Genetic variants of Neuregulin 1 (NRG1) and its neuronal tyrosine kinase receptor ErbB4 are associated with risk for schizophrenia, a neurodevelopmental disorder characterized by excitatory/inhibitory imbalance and dopamine (DA) dysfunction. To date, most ErbB4 studies have focused on GABAergic interneurons in the hippocampus and neocortex, particularly fast-spiking parvalbumin-positive (PV+) basket cells. However, NRG has also been shown to modulate DA levels, suggesting a role for ErbB4 signaling in dopaminergic neuron function...
