Most individuals identified as ultra high-risk for psychosis (UHR) do not develop frank psychosis. They continue to exhibit subthreshold symptoms, or go on to fully remit. Prior work has shown that the volume of CA1, a subfield of the hippocampus, is selectively reduced in the early stages of schizophrenia. Here, we aimed to determine whether patterns of volume change of CA1 are different in UHR individuals who do or do not achieve symptomatic remission. Structural MRI scans were acquired at baseline and at 1-2 follow-up time points (at 12-month intervals) from 147 UHR and healthy control subjects...

Objectives: Brain maturation differs depending on the area of the brain and sex. Girls show an earlier peak in maturation of the prefrontal cortex. Although differences between adult females and males with schizophrenia have been widely studied, there has been less research in girls and boys with psychosis. The purpose of this study was to examine differences in verbal and visual memory, verbal working memory, auditory attention, processing speed, and cognitive flexibility between boys and girls...

BACKGROUND: The prevalence of childhood trauma and its impact on clinical outcomes in hospitalized patients with mood disorders is unknown. We studied the frequency of childhood trauma among inpatient adults with mood disorders and its association with clinical outcomes. METHODS: Patients admitted to our hospital with a primary diagnosis of mood disorders completed the short form of the Early Trauma Inventory-Self-Report (ETISR-SF), the Sheehan Disability Scale, and the Clinician-Rated Dimensions of Psychosis Symptom Severity scale...

OBJECTIVES: Few people who use stimulants seek clinical treatment. This study sought to describe a cohort of stimulant users who attended a stimulant-specific treatment service, Access Point, in Melbourne, Australia between 2008 and 2014. METHODS: A retrospective audit of the records of adults ( n = 175) who sought treatment for stimulant use at a stimulant-specific outpatient treatment service was conducted. RESULTS: Service users had a median age of 32 (range = 19-54)...

INTRODUCTION: Data from the literature suggests that some first episode psychosis (FEP) patients may recover without antipsychotic medication. There is however no reliable way to identify them. In a previous paper we found, in a cohort of 584 FEP patients, that those consistently refusing medication had poorer pre-morbid functioning, less insight, higher rate of substance use and poorer outcome. However, some medication refusers, had a favourable outcome. The study aim was to identify predictors of good short term outcome despite non-exposure to medication...

Subjective quality of life (SQoL) has been increasingly studied in first-episode psychosis (FEP). Prior research primarily examined the impact of psychiatric symptoms on SQoL. Relationship between treatment-related factors and SQoL is under-studied. In this study, 159 Chinese patients who had completed 2-year treatment from early intervention service in Hong Kong were recruited. Assessments on premorbid adjustment, clinical profiles including social anxiety measure, functioning, antipsychotic-induced extrapyramidal side-effects and attitude toward medication treatment were conducted...

The description of longitudinal bio-psycho-social profiles in FEP samples may be useful for the prediction of disability trajectories. This study aimed to describe the differences between disability status of FEP patients at baseline and their change over time, analysing how variables associated to the psychological status, and the environment of the patient can affect his or her disability trajectory, once the influence of health condition and socio-demographic variables has been controlled for. Using data from a 3-year follow-up study on early psychosis (PAFIP), a multilevel structure in which the longitudinal measurements (within level) were nested within the individuals (between level), was modeled...

Psychosis is one of the debilitating non-motor symptoms (NMS) of Parkinson's disease (PD). Cognitive impairment is considered to be a risk factor for emergence of psychosis in PD. Early detection of relevant cognitive impairment may serve as a predictor for development of psychosis, with implications for prevention and early intervention. However, the exact pattern of cognitive impairment associated with psychosis is not clear. In this article, we aim to critically review the literature on case-control studies in PD patients with and without psychosis in order to understand the pattern of cognitive impairment in those with psychosis...

BACKGROUND: The main focus of research on clinical high-risk states for psychosis (CHR) has been the development of algorithms to predict psychosis. Consequently, other outcomes have been neglected, and little is known about the long-term diagnostic and functional outcome among those not converting to psychosis. METHODS: In a naturalistic study, incidence, persistence, and remission rates of CHR states according to symptomatic ultra-high risk or cognitive disturbances criteria were investigated in 160 of 246 outpatients of an early detection of psychoses service (21...

Clinical staging improved the possibility of intervening during the psychosis prodrome to limit progression of illness. The current study aimed to validate a novel 4-stage severity-based model with a focus on clinical change over time and risk for conversion to psychosis. One hundred seventy-one individuals at clinical high risk (CHR) for psychosis were followed prospectively (3 ± 1.6 y) as part of the Recognition and Prevention (RAP) program and divided into 4 diagnostic stages according to absence/presence and severity of attenuated positive symptoms...

BACKGROUND: Functional decline among patients with mental illness is not unique to individuals with psychotic disorders. Despite this, research on early predictors of functional outcome mainly focused on individuals thought to have an 'at risk mental state' (ARMS) for psychosis. There is evidence suggesting that certain early vulnerability markers, such as neurological soft signs (NSS), may explain variability in functional outcomes independent of the level of psychosis risk and the traditional diagnostic classification...

BACKGROUND: Studies show that the Internet has become an influential source of information for people experiencing serious psychiatric conditions such as schizophrenia spectrum disorders or other psychotic disorders, among which the rate of Internet users is growing, with rates ranging from 33.3% to 79.5% given the country. Between 20.5% and 56.4% of these Internet users seek mental health information. OBJECTIVE: Focusing on this population's Web searches about their mental health, this paper examines what type of content they look for and what could be the benefits and disadvantages of this navigation...

BACKGROUND: Amotivation is prevalent in first-episode psychosis (FEP) patients and is a major determinant of functional outcome. Prediction of amotivation in the early stage of psychosis, however, is under-studied. We aimed to prospectively examine predictors of amotivation in FEP patients in a randomized-controlled trial comparing a 1-year extension of early intervention (Extended EI, 3-year EI) with step-down psychiatric care (SC, 2-year EI). METHODS: One hundred sixty Chinese patents were recruited from a specialized EI program for FEP in Hong Kong after they have completed this 2-year EI service, randomly allocated to Extended EI or SC, and followed up for 12 months...

PURPOSE: Schizophrenia is a psychiatric disorder characterized by disordered thoughts, abnormal social behaviors, flat affect, and auditory or visual hallucinations. The current study aims to investigate alterations in brain metabolism in patients near the onset of psychosis (early-phase psychosis, EPP), to characterize abnormalities during the early stages of schizophrenia. To this end, we used magnetic resonance imaging (MRI) and spectroscopy (MRS) to measure metabolite levels and subsequently monitor the effect of treatment with N-acetylcysteine (NAC)...

OBJECTIVE: Increasing evidence supports the effectiveness of comprehensive early intervention at first onset of psychotic symptoms. Implementation of early intervention programs will require population-based data on overall incidence of psychotic symptoms and on care settings of first presentation. METHODS: In five large health care systems, electronic health records data were used to identify all first occurrences of psychosis diagnoses among persons ages 15-59 between January 1, 2007, and December 31, 2013 (N=37,843)...

About one third of individuals with 22q11.2 deletion syndrome (22q11.2DS) develop schizophrenia. Notably, a full-blown psychotic disorder is usually preceded by subthreshold symptoms. Therefore, it is important to identify early signs of psychosis in this population, a task that is complicated by the intellectual disabilities typically seen in 22q11.2DS. We aimed to identify subthreshold psychotic symptoms that distinguish 22q11.2DS from other neurodevelopmental disorders. The study included two independent cohorts from Tel Aviv and Philadelphia...

A critical research goal is to identify modifiable risk factors leading to functional disabilities in young psychiatric patients. The authors developed a multidimensional trans-diagnostic predictive model of functional outcome in patients with the recent-onset of a psychiatric illness. Baseline clinical, psychosis-risk status, cognitive, neurological-soft-signs measures, and dopamine-related-gene polymorphisms (DRD1-rs4532, COMT-rs165599, and DRD4-rs1800955) were collected in 138 young non-psychotic outpatients...

BACKGROUND: Stigma toward psychosis can prevent social attendance and help-seeking behavior. Early detection and intervention has been shown to improve patient outcome in schizophrenia. The aim of this study was to reveal the characteristics and formulation process of stigma toward each clinical stage of schizophrenia, taking people's backgrounds into consideration. METHODS: The participants consisted of three groups: general public, patients with mental illness, and psychiatric professionals...

OBJECTIVES: Community Treatment Order (CTO) is a legal regime that obliges patients suffering mental disorder to adhere to treatment in the community and allows for a swift admission to hospital if necessary. Study aims were to: (i) determine CTO frequency in a large representative sample of first episode psychosis (FEP) patients; (ii) compare the characteristics of patients with or without CTO before entry, during treatment and at discharge from an early psychosis program. METHODS: Information on 660 patients treated at the Early Psychosis Prevention and Intervention Centre (EPPIC) between 1998 and 2000 was collected from medical files...
