OBJECTIVE: The objective of this article is to identify best practices in the diagnosis and assessment of patients with schizophrenia spectrum and other psychotic disorders. The diagnosis and assessment may occur in a range of situations from the emergency room to the outpatient clinic and at different stages of the disorder. The focus may be on acute exacerbations of illness, residual symptoms, levels of function, or changes in the response to treatment. METHODS: A systematic search was conducted for guidelines published in the last 5 years for schizophrenia and schizophrenia spectrum disorders...

BACKGROUND: The cerebellum, which modulates affect and cognition in addition to motor functions, may contribute substantially to the pathophysiology of mood and psychotic disorders, such as bipolar disorder. A growing literature points to cerebellar abnormalities in bipolar disorder. However, no studies have investigated the topographic representations of resting state cerebellar networks in bipolar disorder, specifically their functional connectivity to cerebral cortical networks. METHODS: Using a well-defined cerebral cortical parcellation scheme as functional connectivity seeds, we compared ten cerebellar resting state networks in 49 patients with bipolar disorder and a lifetime history of psychotic features and 55 healthy control participants matched for age, sex, and image signal-to-noise ratio...

Latency of the acoustic startle response is the time required from the presentation of startling auditory stimulus until the startle response is elicited and provides an index of neural processing speed. Latency is prolonged in subjects with schizophrenia compared to controls in some but not all studies and is 68-90% heritable in baseline startle trials. In order to determine the genetic association with latency as a potential inroad into genetically based vulnerability to psychosis, we conducted a gene-based study of latency followed by an independent replication study of significant gene findings with a single-nucleotide polymorphism (SNP)-based analysis of schizophrenia and control subjects...

BACKGROUND: Despite the boom in new technologically based interventions for people with psychosis, recent studies suggest medium to low rates of adherence to these types of interventions. The benefits will be limited if only a minority of service users adhere and engage; if specific predictors of adherence can be identified then technologies can be adapted to increase the service user benefits. OBJECTIVE: The study aimed to present a systematic review of rates of adherence, dropout, and approaches to analyzing adherence to newly developed mobile and Web-based interventions for people with psychosis...

Social anxiety (SA) is frequently observed among patients diagnosed with psychosis as well as among individuals with delusion-like experiences (DLEs). A heightened level of SA has been recognized to precede the development of psychotic symptoms; however, the detailed mechanisms that link SA to delusional ideation remain unrecognized. Since social anxiety is associated with the presence of cognitive biases and biased cognitive processes have been found to play a role in the development and maintenance of delusions, we hypothesized that cognitive biases may mediate in the relationship between social anxiety and DLEs...

Intraperitoneal free air (IFA) is sometimes accompanied by pneumatosis cystoides intestinalis (PCI); therefore, proper diagnosis is essential for PCI management. We report two cases of PCI with IFA. A 70-year-old female taking anti-psychotic medication for schizophrenia presented with repeated vomiting and high-grade fever. Computed tomography revealed small, linear gaseous cysts in the intestinal wall along with IFA. Although there was no sign of peritoneal irritation, intestinal perforation was not excluded...

Importance: A higher out-of-pocket price for mental health care may lead not only to cost savings but also to negative downstream consequences. Objective: To examine the association of higher patient cost sharing with mental health care use and downstream effects, such as involuntary commitment and acute mental health care use. Design, Setting, and Participants: This difference-in-differences study compared changes in mental health care use by adults, who experienced an increase in cost sharing, with changes in youths, who did not experience the increase and thus formed a control group...

AIM: Second-generation antipsychotics are commonly used to treat schizophrenia, but may cause metabolic syndrome (MetS) in a subset of patients. The mechanisms of antipsychotic-related metabolic changes remain to be established, especially in first-episode psychosis (FEP) patients. METHODS: In the present study, we used a chip technology to measure metabolic (C-peptide, insulin, leptin, adiponectin and resistin) and inflammatory biomarkers (ferritin, interleukin-6, interleukin-1α, tumour necrosis factor-α and plasminogen activator inhibitor-1) in the serum samples of a population of FEP patients before and after 7 months of antipsychotic drug treatment, compared to control subjects (CS)...

OBJECTIVE: A population health approach to mental health service planning requires estimates that align interventions with the needs of people with mental illness. The primary objective was to estimate the number of people in Australia living with severe and persistent mental illness who have complex, multi-agency needs. The secondary objective was to describe the possible service needs of individuals with severe mental illness. METHODS: We disaggregated the estimated 12-month prevalence of adults with severe mental illness into needs-based sub-groups, using multiple data sources...

BACKGROUND: While antipsychotic medications are the mainstay of therapy for individuals with schizophrenia and psychotic disorders, their use is associated with adverse effects on physical health that require the attention and care of prescribers. METHODS: We used the ADAPTE process to adapt existing guideline recommendations from the National Institute for Health and Care Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN) guidelines on the dosing of antipsychotics and antipsychotic polypharmacy, screening for adverse effects of antipsychotics, and management of metabolic and extrapyramidal side effects to the Canadian context...

Zinc participation is essential for all physiological systems, including neural functioning, where it participates in a myriad of cellular processes. Converging clinical, molecular, and genetic discoveries illuminate key roles for zinc homeostasis in association with clinical depression and psychosis which are not yet well appreciated at the clinical interface. Intracellular deficiency may arise from low circulating zinc levels due to dietary insufficiency, or impaired absorption from aging or medical conditions, including alcoholism...
