Few studies have investigated the relationship between obsessive-compulsive symptoms (OCS) and clinical variables, and cognition in individuals at ultra high-risk (UHR) for psychosis. The aim of this study was to evaluate the frequency of OCS and their relationship with clinical variables and cognitive functions in individuals at UHR. Eighty-four individuals at UHR for psychosis were administered the Brief Psychiatric Rating Scale, the Yale-Brown Obsession Compulsion Symptom Check List and, the Calgary Depression Scale for Schizophrenia...

BACKGROUND: Both major depressive disorder (MDD) and first episode schizophrenia spectrum (FES) are associated with significant neurocognitive deficits. However, it remains unclear whether the neurocognitive deficits in individuals with FES are more severe if there is comorbid depressive disorder. The aim of this study was to compare the neurocognitive profiles between those with and without full-threshold depressive disorder in FES. METHOD: This study involved secondary analysis of baseline data from a randomized controlled trial of vocational intervention for young people with first-episode psychosis (N = 82; age range: 15-25 years)...

Neuroactive steroids, including testosterone, dehydroepiandrosterone (DHEA) and its sulfate (DHEA-S) might play an important role in the pathophysiology of schizophrenia. Therefore, we performed a systematic review and meta-analysis of studies comparing the levels of testosterone, DHEA and DHEA-S in patients with schizophrenia and healthy controls. We searched electronic databases from their inception until Oct 29, 2017. Effect size (ES) estimates were calculated as Hedges' g. Data analysis was performed using random-effects models...

OBJECTIVE: Carers of people with psychosis may experience psychological distress and caregiving burden. However, few studies have examined both psychological and physical health of carers of young people with first episode psychosis (FEP). METHOD: A total of 32 young people with FEP and 42 of their carers were recruited from a mental health service. Standardised scales were administered to assess carers' psychological distress and risk for development of Type 2 diabetes...

Schizophrenia and other types of psychosis incur suffering, high health care costs and loss of human potential, due to the combination of early onset and poor response to treatment. Our ability to prevent or cure psychosis depends on knowledge of causal mechanisms. Molecular genetic studies show that thousands of common and rare variants contribute to the genetic risk for psychosis. Epidemiological studies have identified many environmental factors associated with increased risk of psychosis. However, no single genetic or environmental factor is sufficient to cause psychosis on its own...

A preregistered systematic review of poststroke psychosis examining clinical characteristics, prevalence, diagnostic procedures, lesion location, treatments, risk factors and outcome. Neuropsychiatric outcomes following stroke are common and severely impact quality of life. No previous reviews have focused on poststroke psychosis despite clear clinical need. CINAHL, MEDLINE and PsychINFO were searched for studies on poststroke psychosis published between 1975 and 2016. Reviewers independently selected studies for inclusion, extracted data and rated study quality...

Poor sleep quality has been repeatedly linked to the entire psychosis continuum, including psychotic-like experiences (PLEs); however, sleep dysfunction is a component of several other psychopathologies that have also been linked to increased risk for PLEs, including depression, anxiety, and post-traumatic stress disorder (PTSD). It has yet to be examined if PLEs are a significant risk factor for poor sleep quality or if this sleep dysfunction is better accounted for by comorbid psychopathology. In 2687 undergraduates, PLEs were evaluated using the positive items of the Prodromal Questionnaire...

BACKGROUND: The aim of this observational study was to investigate the relationship between metabolic factors and use of selective serotonin reuptake inhibitors (SSRIs) combined with olanzapine, quetiapine or risperidone. METHODS: Data from the Norwegian Thematically Organized Psychosis study, a cross-sectional study on 1301 patients with schizophrenia (n=868) or bipolar disorder (n=433), were analyzed. As exposure variables in the linear regression model were included the dose or serum concentration of SSRIs (n=280) and of olanzapine (n=398), quetiapine (n=234) or risperidone (n=128)...

BACKGROUND: Previous studies in individual countries have identified inconsistent predictors of length of stay (LoS) in psychiatric inpatient units. This may reflect methodological inconsistencies across studies or true differences of predictors. In this study we assessed predictors of LoS in five European countries and explored whether their effect varies across countries. METHODS: Prospective cohort study. All patients admitted over 14 months to 57 psychiatric inpatient units in Belgium, Germany, Italy, Poland and United Kingdom were screened...

BACKGROUND: The 22q11.2 deletion syndrome (22q11DS) is the most common genetic syndrome associated with schizophrenia. The goal of this study was to evaluate longitudinally the interaction between neurocognitive functioning, the presence of subthreshold psychotic symptoms (SPS) and conversion to psychosis in individuals with 22q11DS. In addition, we attempted to identify the specific neurocognitive domains that predict the longitudinal evolution of positive and negative SPS, as well as the effect of psychiatric medications on 22q11DS psychiatric and cognitive developmental trajectories...

BACKGROUND: Cognitive deficits are a core feature of early stages in schizophrenia. However, the extent to which antipsychotic (AP) have a deleterious effect on cognitive performance remains under debate. We aim to investigate whether anticholinergic loadings and dose of AP drugs in first episode of psychosis (FEP) in advanced phase of remission are associated with cognitive impairment and the differences between premorbid intellectual quotient (IQ) subgroups. METHODS: Two hundred and sixty-six patients participated...

BACKGROUND: The impact of psychosis on the treatment of bipolar depression is remarkably understudied. The primary aim of this study was to compare treatment outcomes of bipolar depressed individuals with and without psychosis. The secondary aim was to compare the effect of lithium and quetiapine, each with adjunctive personalized treatments (APTs), in the psychotic subgroup. METHODS: We assessed participants with DSM-IV bipolar depression included in a comparative effectiveness study of lithium and quetiapine with APTs (the Bipolar CHOICE study)...

Background: Epidemiological studies recognize cannabis intake as a risk factor for schizophrenia, yet the majority of adolescents who use marijuana do not develop psychosis. Similarly, the abuse of synthetic cannabinoids poses a risk for psychosis. For these reasons, it is imperative to understand the effects of adolescent cannabinoid exposure in susceptible individuals. Method: We have recently developed a novel rodent model of schizophrenia susceptibility, the F2 MAM rat, where only a proportion (~40%) of rats display a schizophrenia-like phenotype...

The schizophrenia spectrum disorders are neurodevelopmental illnesses with a lifetime prevalence near 1%, producing extensive functional impairment and low expectations for recovery. Until recently, treatment in the United States has largely attempted to stabilize individuals with chronic schizophrenia. The identification and promotion of evidence-based practices for schizophrenia via the Patient Outcomes Research Team, combined with international studies supporting the value of early intervention, provided the foundation for the Recovery After an Initial Schizophrenia Episode (RAISE) project...

BACKGROUND: Ethnic minority individuals have an increased risk of developing a psychotic disorder, particularly if they live in areas of ethnic segregation, or low own group ethnic density. The neurobiological mechanisms underlying this ethnic minority associated risk are unknown. We used functional MRI to investigate neural responses to faces of different ethnicity, in individuals of black ethnicity, and a control group of white British ethnicity individuals. METHODS: In total 20 individuals of black ethnicity, and 22 individuals of white British ethnicity underwent a 3T MRI scan while viewing faces of black and white ethnicity...

Substance use disorders are becoming an increasingly significant problem in general hospitals and hence play a key role in consultation- and liaison psychiatry. Diverse psychotropic effects of various substances mimic psychiatric disorders. An alcohol intoxication can present depressive or manic symptoms, a cannabis delirium can present as a psychosis while stimulants use can suggest the diagnosis of an anxiety disorder. Obtaining dual diagnoses by identifying substance-induced and non-substance-induced psychopathologies is clinically challenging...

PURPOSE: The aim of the review is to understand the relationships between loneliness and related psychological and social factors in individuals with psychosis. Loneliness is poorly understood in people with psychosis. Given the myriad of social challenges facing individuals with psychosis, these findings can inform psychosocial interventions that specifically target loneliness in this vulnerable group. METHODS: We adhered to the PRISMA guidelines and systematically reviewed empirical studies that measured loneliness either as a main outcome or as an associated variable in individuals with psychosis...

Activated microglia express the translocator protein (TSPO) on the outer mitochondrial membrane. 18F-PBR111 is a second-generation positron emission tomography (PET) ligand that specifically binds the TSPO, allowing in-vivo visualization and quantification of neuroinflammation. The aim of this study is to evaluate if the test-retest variability of 18F-PBR111 in healthy controls is acceptable to detect a psychosis-associated neuroinflammatory signal in schizophrenia. Methods: Dynamic 90-min 18F-PBR111 scans were obtained in 17 healthy male controls (HC) and 11 male schizophrenia patients during a psychotic episode (SP)...

BACKGROUND: Receptor imaging studies have reported increased amphetamine-induced dopamine release in subjects with schizophrenia (SCH) relative to healthy control subjects (HCs). A limitation of these studies, performed with D2/3 antagonist radiotracers, is the failure to provide information about D2/3 receptors configured in a state of high affinity for the agonists (i.e., D2/3 receptors coupled to G proteins [D2/3 HIGH]). The endogenous agonist dopamine binds with preference to D2/3 HIGH receptors relative to D2/3 LOW receptors, making it critical to understand the status of D2/3 HIGH receptors in SCH...

Systemic lupus erythematosus (SLE) or Lupus is a chronic and idiopathic autoimmune connective tissue disease that involves several organs and organ systems. SLE may lead to a group of psychiatric manifestations, including delirium, anxiety disorders, cognitive dysfunction, mood disorders, and psychosis, which are caused by organic or non-organic factors. In addition, it is thought that the most common cause of neuropsychiatric lupus is corticosteroid use; central nervous system involvement and inflammatory processes also have an important role in the development of psychiatric manifestations...
