INTRODUCTION: Brain-derived neurotrophic factor (BDNF) plays a crucial role in neurodevelopment, synaptic plasticity and neuronal function and survival. Serum and plasma BDNF levels are moderately, but consistently, decreased in patients with schizophrenia (SCZ) compared with healthy controls. There is a lack of knowledge, however, on the temporal manifestation of this decline. Clinical, illness course and treatment factors might influence the variation of BDNF serum levels in patients with psychosis...

PURPOSE: Glutamatergic models of psychosis propose that dysfunction of N-methyl-d-aspartate (NMDA) receptors, and associated excess of glutamate, may underlie psychotic experiences in people with schizophrenia. However, little is known about the specific relation between glutamate and auditory verbal hallucinations (AVH) in patients with psychosis. In this study, levels of glutamate+glutamine (Glx) in the left lateral prefrontal lobe were determined using proton magnetic resonance spectroscopy ((1)H MRS) to calculate their association with AVH...

In promoting optimal recovery in persons with psychosis, psychological interventions have become a key element of treatment, with cognitive behavioural therapy being widely recommended in clinical practice guidelines. One key area of development has been the trialling of "third wave" cognitive behavioural interventions, which promote mindfulness, acceptance and compassion as means of change. Trials to date have demonstrated encouraging findings, with beneficial effects observed on measures of psychotic symptoms...

BACKGROUND: According to the projections of the World Health Organization, 15% of all disabilities will be associated with mental illnesses by 2020. One of the mental disorders with the largest social impacts due to high personal and family costs is psychosis. Among the most effective psychological approaches to treat schizophrenia and other psychotic disorders at the world level is cognitive behavioral therapy. Recently, cognitive behavioral therapy has introduced several tools and strategies that promote psychological processes based on acceptance and mindfulness...

There is an increasing body of evidence suggesting a significant comorbidity between psychotic disorders such as schizophrenia and attention-deficit/hyperactivity disorder (ADHD) or autism-spectrum disorders (ASD). Recently, research on psychosis-proneness in otherwise healthy individuals has been a promising way to better understand the mechanisms underlying psychosis. As both ADHD and ASD symptoms show a normal distribution in the general population, such trait comorbidity may confound studies on psychosis-proneness...

Dopamine D2-receptor blockade by antipsychotic medication reduces psychotic symptoms, but may reduce subjective well-being. The current study aims to further explore the relation between dopamine D2-receptor affinity and subjective well-being within a large sample of patients with psychotic disorders. Patients participated in a longitudinal naturalistic cohort study: the Genetic Risk and Outcome of Psychosis (GROUP) study. Three groups of antipsychotic medication were created on the basis of their affinity for the D2-receptor: (i) loose or partial agonistic binding, (ii) moderate binding, and (iii) tight binding...

#7
REVIEW
Rafael G Dos Santos, José Carlos Bouso, Jaime E C Hallak
Ayahuasca is a hallucinogen brew traditionally used for ritual and therapeutic purposes in Northwestern Amazon. It is rich in the tryptamine hallucinogens dimethyltryptamine (DMT), which acts as a serotonin 5-HT2A agonist. This mechanism of action is similar to other compounds such as lysergic acid diethylamide (LSD) and psilocybin. The controlled use of LSD and psilocybin in experimental settings is associated with a low incidence of psychotic episodes, and population studies corroborate these findings. Both the controlled use of DMT in experimental settings and the use of ayahuasca in experimental and ritual settings are not usually associated with psychotic episodes, but little is known regarding ayahuasca or DMT use outside these controlled contexts...

The heightened risk of persons with serious mental illness to contract and transmit human immunodeficiency virus (HIV) is a public health problem. Here we evaluate the interaction between psychiatric diagnosis and response to a community based-intervention targeted at treatment adherence in 236 HIV+ persons with co-occurring mental illness. To examine differential effectiveness of the intervention for categories of patient diagnosis, we reanalyzed the data after stratifying participants into two diagnostic groups: (1) participants with depressive disorders without psychosis and (2) participants with a psychotic or bipolar disorder...

The management of cryptococcal infections is often difficult. This can, in part, be attributed to the fungistatic nature of fluconazole, which may result in cells disseminating to give rise to pathogen-emergent psychosis following brain inflammation. This chance at treatment failure has necessitated the current study wherein the antimicrobial quality of anti-psychotic drugs viz. quetiapine and olanzapine, was assessed. The response of test strains toward quetiapine or olanzapine alone and in combined therapy with fluconazole or amphotericn B was measured...

BACKGROUND: Little is known about the impact of urbanicity, adverse neighborhood conditions and violent crime victimization on the emergence of adolescent psychotic experiences. METHODS: Participants were from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative cohort of 2232 British twins who were interviewed about adolescent psychotic experiences at age 18. Urbanicity, neighborhood characteristics, and personal victimization by violent crime were measured during childhood and adolescence via geocoded census data, surveys of over 5000 immediate neighbors of the E-Risk participants, and interviews with participants themselves...

BACKGROUND: The ecological validity of retrospective measures of social functioning is currently unknown in patients with schizophrenia. In the present study, patients with a diagnosis of non-affective psychosis were compared with controls on two measures of social functioning: the Social Functioning Scale (SFS) and daily-life measures collected with the Experience Sampling Methodology (ESM). The associations between both measures were examined in each group of participants to test for the ecological validity of the SFS...

BACKGROUND: Gender differences regarding psychiatric ill-health are well known in the general population. However, not much research is done on people with intellectual disability, and especially not among older people with intellectual disability. METHODS: People with intellectual disability aged 55+ years in 2012 in Sweden were identified through a register containing information on those receiving support and service for this type of disability. The cohort comprised 3609 women and 4327 men with mean age 65 and 64 years, respectively...

BACKGROUND: The presence of psychotic symptoms in bipolar disorder (BD) is considered a feature of higher severity of illness and, in particular, of manic episodes in bipolar I disorder (BD I). However, the possibility to apply the "with psychotic features" specifier to major depressive episodes in either bipolar II disorder (BD II) or BD I highlights the need for additional research in this area. METHODS: The present study assessed the lifetime presence of psychotic symptoms and related socio-demographic and clinical features in a large sample of BD patients (N=360), with (BDPs, N=207) and without a lifetime history of psychosis (BDNPs, N=153)...

OBJECTIVE: Psychotic disorders in childhood and early adolescence often progress to chronic schizophrenia, but in many cases there are diagnosable medical and genetic causes or risk factors. We reviewed our clinical experience and the relevant literature to identify these factors and to define their clinical features, appropriate work-up and treatment. METHOD: We reviewed the results of comprehensive medical evaluations of 160 psychotic children and adolescents in our center...

The current study examined quantitative measures of psychosis proneness in a nonpsychotic population, in order to elucidate their underlying genetic architecture and to observe if there is any commonality to that already detected in the studies of individuals with overt psychotic conditions, such as schizophrenia and bipolar disorder. Heritability, univariate and multivariate genome-wide association (GWAs) tests, including a series of comprehensive gene-based association analyses, were developed in 4269 nonpsychotic persons participating in the Northern Finland Birth Cohort 1966 study with information on the following psychometric measures: Hypomanic Personality, Perceptual Aberration, Physical and Social Anhedonia (also known as Chapman's Schizotypia scales), and Schizoidia scale...

Objective: Several ethnic minority groups experience elevated rates of first-episode psychosis (FEP), but most studies have been conducted in urban settings. We investigated whether incidence varied by ethnicity, generation status, and age-at-immigration in a diverse, mixed rural, and urban setting. Method: We identified 687 people, 16-35 years, with an ICD-10 diagnosis of FEP, presenting to Early Intervention Psychosis services in the East of England over 2 million person-years...

OBJECTIVE: Despite strong evidence supporting the effectiveness of cognitive-behavioral therapy for psychosis (CBTp), most clinicians in the United States have received little or no training in the approach and access remains very low, indicating a potential role for technology in increasing access to this intervention. Coping With Voices (CWV) is a 10-session, interactive, Web-based CBTp skills program that was developed to meet this need, and was shown to be feasible and associated with reduced severity of auditory hallucinations in a previous pilot study...

Organic underpinning of a psychotic disturbance is often missed. Arachnoid cysts are considered a rare neurological tumor, few of which exhibit any symptomatology. In most cases, they are diagnosed by accident. Literature regarding the coexistence of arachnoid cysts with psychiatric disorders is sparse. Here, we present a case who presented with a typical presentation of psychosis which was not enough for suspecting for an organic etiology.

Prader-Willi Syndrome (PWS) is a complex neurogenetic disorder caused by loss of the paternal 15q11.2-q13 locus, due to deletion (DEL), maternal uniparental disomy (mUPD), or imprinting center defects. Individuals with mUPD have up to 60% risk of developing psychosis in early adulthood. Given the increasing evidence for white matter abnormalities in psychotic disorders, we investigated white matter microstructure in children and adolescents with PWS, with a particular emphasis on the DEL and mUPD subtypes. Magnetic resonance diffusion weighted images were acquired in 35 directions at 3T and analyzed using fractional anisotropy (FA), mean, axial, and radial diffusivity (MD, AD, RD) values obtained by tract-based spatial statistics (TBSS) in 28 children and adolescents with PWS and 61 controls...

Cannabis is the third most common recreational drug used world-wide after tobacco and alcohol. Globally, cannabis legalization is becoming more common. In light of its known link to psychosis development, it is imperative that we are well-informed regarding the impact of cannabis on the course of psychosis, in both males and females. However, the majority of the work to date on the role of cannabis in psychosis outcomes has not had a gender focus, important when considering patient specific treatments. This review examines what is currently known, from gender focused studies, about the interaction of gender, cannabis use and psychotic disorders...
