OBJECTIVE: Maintenance treatment of schizophrenia with antipsychotic medications has become a standard for the prevention of psychotic relapse. However, little is known about the effectiveness of antipsychotic drugs for maintenance treatment in "real-world" populations with schizophrenia. We carried out a prospective study to assess the effectiveness of the most frequently prescribed antipsychotic drugs in the maintenance treatment of schizophrenia from 2 community settings. METHODS: This study was conducted from October 2011 to December 2014...

BACKGROUND: Bipolar disorder (BD) may be characterized by the presence of psychotic symptoms and comorbid substance abuse. In this context, structural and metabolic dysfunctions have been reported in both BD with psychosis and addiction, separately. In this study, we aimed at identifying neural substrates differentiating psychotic BD, with or without substance abuse, versus substance-induced psychosis (SIP) by coupling, for the first time, magnetic resonance imaging (MRI) and positron emission tomography (PET)...

Adults with psychotic disorders have abnormal connectivity of fronto-temporal networks. However, whether these abnormalities are present in adolescents with early psychosis has not been fully assessed. One-hundred and thirty-nine adolescents aged 12-18 underwent resting-state functional magnetic resonance imaging and diffusion tensor imaging. Following motion correction, data were available for 44 participants with a psychosis risk syndrome, 34 patients with a first episode psychosis (FEP) and 35 healthy controls...

PURPOSE: The incidence of psychotic disorders varies in different geographical areas. As there have been no reports from Southern Italy, this study aimed to determine the incidence rate of first-episode psychosis in Palermo, Sicily. METHODS: All patients, aged 18-65 years, presenting with a first episode of psychosis (FEP) (ICD-10 F20-29, F30-33) to mental health services in Palermo, were recorded over a 3-year period. Incidence rates of psychotic disorders and their 95% confidence intervals (95% CI) were estimated...

BACKGROUND: Affective syndrome is thought to be a key feature that differentiates schizophrenia from schizoaffective disorder (SA) and bipolar disorder with psychotic features (BDP). However genetic underpinnings of these differences remain unresolved. OBJECTIVES: We compared clinical variables of affective psychoses (SA, BDP and schizophrenia with affective symptoms (AFF SCZ)) and schizophrenia without affective symptoms (non-AFF SCZ) and searched for a genetic variant that may differentiate affective psychosis from non-AFF SCZ...

BACKGROUND: Dopaminergic dysfunction, namely, dopamine transporter (DAT) availability variations in patients with drug-naive schizophrenia after long-term treatment, is still not well understood. The aims of the study were to explore (i) whether the DAT availability in patients with drug-naive schizophrenia differed after antipsychotic treatment and (ii) whether treatment with different generations of antipsychotics influenced the DAT availability after follow-up for 6 months. METHODS: Twenty-four first-episode, drug-naive patients with schizophrenia were divided into first- and second-generation antipsychotic groups naturalistically...

BACKGROUND: Crisis resolution and home treatment teams (CRTs) offer an alternative to hospital admission for patients undergoing mental health crises in the UK. Few studies have been done to examine predictors of relapse and readmission after contact with CRTs. METHODS: We used the Clinical Record Interactive Search to identify all patients receiving care from CRTs in two National Health Service (NHS) mental health trusts in London: Camden and Islington NHS Foundation Trust and South London and Maudsley NHS Foundation Trust...

It has been well-demonstrated that Expressed Emotion (EE) in caregivers of schizophrenia patients is related to their illness attributions, but little is known about relatives' cognitive and emotional appraisals at early stages of psychosis. This study examined differences on the relationships of EE with distress and illness attributions in 78 relatives of At-Risk Mental States (ARMS) and First-Episode of Psychosis (FEP) patients, and which of those variables better predicted EE. Criticism and Emotional Over-Involvement (EOI) were associated with distress and with several illness attributions in both groups...

Auditory verbal hallucinations (AVH) occur in psychotic disorders, but also as a symptom of other conditions and even in healthy people. Several current theories on the origin of AVH converge, with neuroimaging studies suggesting that the language, auditory and memory/limbic networks are of particular relevance. However, reconciliation of these theories with experimental evidence is missing. We review 50 studies investigating functional (EEG and fMRI) and anatomic (diffusion tensor imaging) connectivity in these networks, and explore the evidence supporting abnormal connectivity in these networks associated with AVH...

Schizophrenia is a debilitating psychiatric disorder seen across the world. Recently, investigators have witnessed an upsurge in research on the potential benefits of early intervention during the prodromal stage: the sooner people start the treatment at their first psychotic episode, the better outcome on symptom relief and better functioning. This paper aims to critically review and synthesize empirical evidence published between 2005 and 2015 regarding the effectiveness of preemptive interventions on transition rate, symptom severity, depression, anxiety, and function level...

Resveratrol, a caloric restriction mimetic, is a naturally occurring polyphenolic compound with antioxidant and anti-inflammatory properties. Oxidative stress has been implicated in the etiology of a number of neuropsychiatric disorders including generalized anxiety and schizophrenia. This study investigated the anxiolytic and antipsychotic potentials of resveratrol in murine models of anxiety and schizophrenia. Mice were pretreated with resveratrol (200 and 400 mg/kg) in 1% carboxymethyl cellulose for 14 days and subjected to behavioural tests on the 15th day...

BACKGROUND: Better understanding of the complex interplay among key determinants of functional outcome is crucial to promoting recovery in psychotic disorders. However, this is understudied in the early course of illness. We aimed to examine the relationships among negative symptoms, neurocognition, general self-efficacy and global functioning in first-episode psychosis (FEP) patients using structural equation modeling (SEM). METHOD: Three hundred and twenty-one Chinese patients aged 26-55 years presenting with FEP to an early intervention program in Hong Kong were recruited...

Psychotic patients are at high risk for developing obesity, metabolic syndrome and type 2 diabetes. These metabolic co-morbidities are hypothesized to be related to both treatment side effects as well as to metabolic changes occurring during the psychosis. Earlier metabolomics studies have shown that blood metabolite levels are predictive of insulin resistance and type 2 diabetes in the general population as well as sensitive to the effects of antipsychotics. In this study, we aimed to identify the metabolite profiles predicting future weight gain and other metabolic abnormalities in psychotic patients...

OBJECTIVE: Taurine is an inhibitory neuromodulatory amino acid in the central nervous system that activates the GABA- and glycine-insensitive chloride channel and inhibits the N-methyl-D-aspartate receptor. It also functions as a neuroprotective agent and has a role in neural development and neurogenesis. The aim of this study was to determine the efficacy of adjunctive taurine in improving symptomatology and cognition among patients with a DSM-IV first-episode psychotic disorder. METHODS: 121 patients with first-episode psychosis, aged 18-25 years, attending early intervention services consented to participate in this randomized, double-blind, placebo-controlled trial conducted from January 2007 to May 2009...

BACKGROUND: 'Acute and transient psychotic disorder' (ATPD) is a category in ICD-10 marked by psychosis with acute onset and early remission. It remains relatively under-researched, despite controversies over its nosological status in the current classification system. AIMS: (1) To assess the changes in diagnosis over time in patients initially diagnosed as ATPD. (2) To identify factors predicting changes in diagnosis, and compare the long-term outcomes of various patterns of diagnostic shift...

This report describes a 63-year-old woman, who had experienced 3 previous episodes of severe major depressive disorder. The first 2 episodes responded to treatment with antidepressants, whereas the third episode was accompanied by psychotic features and responded well to treatment with electroconvulsive therapy (ECT). After a severe relapse, the patient responded very slowly to a second course of ECT and failed to achieve full remission. Within a few weeks, she had another severe relapse and responded very rapidly to a combination of ECT and imipramine...

Objective: There is considerable evidence that patients with schizophrenia have neurocognitive and social-cognitive deficits. It is unclear how such deficits in first-episode schizophrenia relate to current clinical symptoms. Method: Fifty-nine patients with first-episode schizophrenia (FES) were tested using the Danish version of NART (premorbid IQ), subtests from WAIS-III (current IQ), and global cognition using Brief Assessment of Cognition in Schizophrena (BACS), a neurocognitive test battery. Social perception was tested using film clips of everyday interactions (TASIT)...

Early psychosis intervention aims to accurately detect adolescents and young adults at risk for major mental disorders, particularly schizophrenia, yet early biomedical diagnostic accuracy remains poor. However, phenomenological approaches focusing on eliciting and understanding the subjective experience of help-seeking youth better detect incipient schizophrenia. The Azima Battery is an occupational therapy projective assessment that uses expressive media in a standard setup, in order to phenomenologically elicit and describe the activity performance and narratives of individuals at risk of, or on, the psychotic-spectrum...
