Luis F S Castro-de-Araujo, Richard A A Kanaan
Patients with first episode psychosis (FEP) present with cognitive deficits and volume differences in certain brain areas. Brain volumetric information further correlates with cognitive testing, and multiple brain areas shows different strengths of correlation with the cognitive functions being tested. Traditionally, these cognitive functions are independently related to volumetric differences, but these functions share variance. Failing to account for this aspect of cognition hinders the proper representation of cognition in neuroimaging studies...

BackgroundThe incidence of psychotic disorders is elevated in some minority ethnic populations. However, we know little about the outcome of psychoses in these populations.AimsTo investigate patterns and determinants of long-term course and outcome of psychoses by ethnic group following a first episode.MethodÆSOP-10 is a 10-year follow-up of an ethnically diverse cohort of 532 individuals with first-episode psychosis identified in the UK. Information was collected, at baseline, on clinical presentation and neurodevelopmental and social factors and, at follow-up, on course and outcome...

BACKGROUND: Psychiatric hospital "Sveti Ivan" in Zagreb, Croatia, offers an outpatient Early intervention programme for patients with psychotic disorders (RIPEPP), consisting of psychoeducational workshops and group psychodynamic psychotherapy. The aim of this study was to describe sociodemographic and baseline characteristics of the participants, in order to provide better understanding of this population, and to assist with the development of more effective therapeutic approaches. SUBJECTS AND METHODS: Since 2008, a total of 245 patients with first episodes of psychosis and their family members participated in the programme...

Neurocognitive impairment is a well-established feature of first-episode psychosis (FEP). Neurotoxicity hypothesis of psychosis suggests that untreated psychosis before the initiation of first effective treatment is associated with loss of acquired cognitive abilities. However, the outcome of the studies investigating the relationship between duration of untreated psychosis (DUP) and cognitive impairment in FEP remains inconclusive. No previous meta-analysis investigating the relationship between DUP and cognitive impairment in FEP has been published...

BACKGROUND: There is a growing interest in the association between schizophrenia and the activation of inflammatory system with signs of acute phase (AP) response. Majority of such studies had focused on C-reactive protein (CRP). The aims of the present study were (i) to examine the gene expression profiles of other acute phase proteins (APP), namely haptoglobin (HP), alpha-1 antitrypsin (A1T), and alpha-2 macroglobulin (A2M) in patients with first episode psychosis (FEP) over a period of three months and (ii) to explore the association between APP levels and severity of symptoms...

BACKGROUND: Cognitive deficits are a core feature of schizophrenia, and impairments in most domains are thought to be stable over the course of the illness. However, cross-sectional evidence indicates that some areas of cognition, such as visuospatial associative memory, may be preserved in the early stages of psychosis, but become impaired in later established illness stages. This longitudinal study investigated change in visuospatial and verbal associative memory following psychosis onset...

BACKGROUND: High suicide attempt (SA) rates have been reported in first-episode psychosis (FEP) patients, particularly during the first year after the illness onset. Despite previous studies establishing several risk factors for suicidal behaviour in FEP, premorbid personality and social cognition have not been sufficiently investigated to date. OBJECTIVE: To test whether personality traits and social cognition are associated with SAs in FEP over a 12-month follow-up...

Patients with first-episode psychosis of peripartum onset commonly prove to have a mood-disorder diathesis; however, a proportion of cases represent first-episode schizophrenia. We present such a case and discuss the clinical relevance of recognizing this small but important population of new mothers. These patients are at considerable risk of misdiagnosis, resulting in ineffective maintenance therapy, poorer recovery of function, and development of treatment resistance. Accurate diagnosis in the peripartum period will impact treatment decisions and long-term therapy...

OBJECTIVE: One reason for worldwide interest in the clinical high-risk (CHR) state for psychosis is its potential as a target for prevention. However, the feasibility and utility of early intervention initiatives that are focused on this stage involve an untested assumption: that most patients with a first episode of psychosis (FEP) experience earlier CHR symptoms. The objective of this study was to identify and characterize the proportion of FEP patients who had experienced such symptoms prior to the onset of their psychosis...

AIM: We explored 2-year outcomes in a sample of clinical high risk (CHR) patients who converted to psychosis despite receiving interventions. METHODS: Of 167 CHR patients, 18 had converted to psychosis and received treatment for their first episode of psychosis in an early intervention service over 2 years. RESULTS: Compared to patients admitted directly to the same early intervention service without having been identified as CHR prior to onset of psychosis, CHR converters were in remission for fewer months (M = 5 vs M = 10); were more likely to be prescribed more than 1 antipsychotic medication (90% vs 68%) and to receive clozapine treatment (38% vs 2%) over 2 years...

Impaired niacin sensitivity (NS) is one of the most replicated findings in untreated schizophrenia, and reflects a disturbance of prostaglandin-mediated pathways in association with deregulated arachidonic acid metabolism, pro-inflammatory activation, and vasomotor function. In ultra-high risk individuals (UHR) increased NS was reported recently, pointing towards dynamic alterations of the underlying pathomechanisms in the period preceding psychosis. However, these characteristics are still unresolved in the diverse UHR groups...

BACKGROUND: There is lack of long-term controlled studies evaluating treatment effects of antipsychotic medication. A complete investigation should include the service user perspective. AIMS: To investigate experiences of clinically recovered service users of antipsychotic medications during and after a first episode of psychosis. METHOD: We used a thematic analytic approach within an interpretative-phenomenological framework. 20 clinically recovered service users were interviewed...

PURPOSE: Some ethnic groups have more negative contacts with health services for first-episode psychosis, likely arising from a complex interaction between ethnicity, socio-economic factors, and immigration status. Using population-based health administrative data, we sought to examine the effects of ethnic group and migrant status on patterns of health service use preceding a first diagnosis of schizophrenia or schizoaffective disorder among people aged 14-35 over a 10-year period. METHODS: We compared access to care and intensity of service use for first-generation ethnic minority groups to the general population of Ontario...

The time period during which patients manifest psychotic or unspecific symptoms prior to treatment (duration of untreated psychosis, DUP, and the duration of untreated illness, DUI) has been found to be moderately associated with poor clinical and social outcome. Equivocal evidence exists of an association between DUP/DUI and structural brain abnormalities, such as reduced hippocampus volume (HV), pituitary volume (PV) and grey matter volume (GMV). Thus, the goal of the present work was to examine if DUP and DUI are associated with abnormalities in HV, PV and GMV...

BACKGROUND: Head-to-head trials to guide antipsychotic treatment choices for paediatric psychosis are urgently needed because extrapolations from adult studies might not be implementable. In this superiority trial with two-sided significance testing, we aimed to compare the efficacy and safety of quetiapine-extended release (quetiapine-ER) versus aripiprazole in children and adolescents with first-episode psychosis, to determine whether differences between the two treatments were sufficient to guide clinicians in their choice of one drug over the other...

BACKGROUND: Deficits in anticipatory pleasure have been consistently shown among chronic, first-episode, and clinical high risk for psychosis populations, but much less attention has been given to non-clinical individuals experiencing attenuated positive psychotic symptoms (APPS). METHODS: Young adults (N = 1839) were administered the Temporal Experience of Pleasure Scale, which measures anticipatory and consummatory pleasure, and the Prodromal Questionnaire, which measures APPS...

BACKGROUND: Assertive community treatment for first-episode psychosis programs have been shown to improve symptoms and reduce service use. There is little or no evidence on whether these programs can increase access to income assistance and improve medication adherence in first episode psychosis patients. This research examines the impact of the Early Psychosis Prevention and Intervention Service (EPPIS) on these outcomes. METHODS: We extracted data on EPPIS patients held in the Data Repository at the Manitoba Centre for Health Policy...

Background: The impact of first episode psychosis (FEP) upon parents' experience of caregiving has been well-documented. However, the determinants and nature of this remain poorly understood in siblings. It is hypothesized that siblings of young people with FEP are also impacted by caregiving and burden. This study aimed to characterize the experience of caregiving for siblings of young people with FEP. Method: Survey methodology was used to explore the experience of 157 siblings in the first 18 months of their brother or sister's treatment for FEP...

In recent years, empirical data and theoretical accounts relating to the relationship between childhood victimization and psychotic experiences have accumulated. Much of this work has focused on co-occurring Posttraumatic Stress Disorder or putative causal mechanisms in isolation from each other. The complexity of posttraumatic stress reactions experienced in psychosis remains poorly understood. This paper therefore attempts to synthesize the current evidence base into a theoretically informed, multifactorial model of posttraumatic stress in psychosis...
