BACKGROUND: The long-term consequences of discontinuing antipsychotic medication after successful treatment of first-episode psychosis are not well studied. We assess the relation between early maintenance therapy decisions in first-episode psychosis and the subsequent clinical outcome at 10 years. METHODS: This is a 10 year follow-up study, spanning Sept 5, 2003, to Dec 30, 2014, of a randomised, double-blind trial in seven centres in Hong Kong in which 178 patients with first-episode psychosis with full positive symptom resolution after at least 1 year of antipsychotic treatment were given maintenance treatment (n=89; oral quetiapine 400 mg daily) or early treatment discontinuation (n=89; placebo) for 12 months...

OBJECTIVE: Amphetamine use and availability have increased in Australia and there are concerns that this has led to more frequent hospital admissions with amphetamine-related psychosis. This study examines whether amphetamine-related admissions to mental health units are more common at times of greater amphetamine availability. METHODS: We conducted an ecological study using aggregate crime and health service data for NSW, Australia, from January 2000 to March 2015...

INTRODUCTION: In recent years, the early detection and treatment of the first episode of schizophrenia (FES) has attracted worldwide attention. In Japan, psychiatric care has changed to an open and accessible framework over the past decade. Therefore, the duration of untreated psychosis (DUP) is thought to have been shortened. The purposes of this study were to investigate whether recent DUP periods are shorter than they were 10 years ago and whether the DUP at present differs among psychiatric facilities...

OBJECTIVE: Right frontal function, as indicated by the N200 component of the event-related potential during target detection, has previously been associated with excitement (excitement, impulsivity, hostility, uncooperativeness) in men with a long-term diagnosis of schizophrenia. The current study investigated excitement in relation to N200 in men who had recently experienced their first episode of psychosis. SUBJECTS AND METHODS: Twenty men who had recently suffered their first psychotic episode underwent a clinical interview and auditory oddball task...

Asperger Syndrome and/or Clinical High Risk of Psychosis? A Differential Diagnostic Challenge This case-study deals with the often difficult differential diagnosis of Asperger syndrome and a clinical high risk state of psychosis, in particular as indicated by attenuated psychotic symptoms, as well as with its therapeutic implications. The presented case is a 10-year old girl, who has not been diagnosed with an autism spectrum disorder before being referred to a specialized center for early detection of psychosis due to possible hallucinatory experiences and delusional ideas...

BACKGROUND: Cognitive problems in people with schizophrenia predict poor functional recovery even with the best possible rehabilitation opportunities and optimal medication. A psychological treatment known as cognitive remediation therapy (CRT) aims to improve cognition in neuropsychiatric disorders, with the ultimate goal of improving functional recovery. Studies suggest that intervening early in the course of the disorder will have the most benefit, so this study will be based in early intervention services, which treat individuals in the first few years following the onset of the disorder...

Recent evidence highlighted a pathogenetic link between redox dysregulation and the early stages of psychosis. Indeed, an increasing number of studies have pointed toward an association between oxidative stress, both at central and peripheral levels, and first psychotic episode. Moreover, basal low antioxidant capacity has been shown to directly correlate with cognitive impairment in the early onset of psychosis. In this context, the possibility to use antioxidant compounds in first psychotic episode, especially as supplementation to antipsychotic therapy, has become the focus of numerous investigations on rodents with the aim to translate data on the possible effects of antioxidant therapies to large populations of patients, with a diagnosis of the first psychotic episode...

PURPOSE: To explore the unintended impact of a targeted case identification (TCI) campaign for first episode psychosis (FEP) on people not experiencing FEP ("non-cases") with respect to referral patterns and reasons for being a non-case. METHODS: Sources of referral, reasons for being a non-case, and subsequent referral destinations of non-cases were examined before and after a TCI. RESULTS: Following the TCI, a greater proportion of non-cases lived outside the study catchment area...

PURPOSE OF REVIEW: The contribution of people with psychosis to homicide statistics is small, but there is a statistically significantly higher rate of homicide among them than in the general population. Legal authorities and the wider public call for more information. Our aim was a narrative synthesis of empirical literature generated by systematic searches for the five complete years 2013-2017. RECENT FINDINGS: One article showed that people with psychosis are five times more likely to be homicide victims than those without, but focus remains on perpetrators...

BACKGROUND: Specialized early intervention (EI) following a first episode of psychosis (FEP) are effective at reducing negative symptoms, although its trajectory warrants systematic assessment. However, findings are equivocal as to whether extended gains are made post 2 years of EI and whether there is additional benefit of extending EI for an additional 3 years. METHODS: Data on 178 FEP patients, from a randomized controlled trial of a 3-year extension of EI service v...

BACKGROUND: Working memory (WM) deficits are a core feature of schizophrenia. Electrophysiological studies suggest that impaired early visual processing may contribute to impaired WM in the visual domain. Abnormal N-methyl-D-aspartate (NMDA) receptor function has been implicated both in WM and in early visual processing deficits in schizophrenia. We investigated whether ketamine, a noncompetitive NMDA antagonist, would replicate in healthy volunteers the WM performance and early visual processing abnormalities we and others have reported in patients with schizophrenia...

AIM: Specialized early intervention (SEI) treatment in meta-analysis has proven to be effective, compared to usual treatment, in treating first-episode psychosis, and the dissemination of SEI services is increasing. A prerequisite for upholding positive effects is to ensure fidelity to the treatment concept once tested. The aim of this study was to map programme fidelity of SEI teams in Denmark by testing a newly developed fidelity scale. METHODS: The 18-item SEI fidelity scale was assessed by visiting SEI teams in person...

BACKGROUND: Failure to respond to antipsychotic medication in schizophrenia is a common clinical scenario with significant morbidity. Recent studies have highlighted that many patients present treatment-resistance from disease onset. We here present an analysis of clozapine prescription patterns, used as a real-world proxy marker for treatment-resistance, in a cohort of 1195 patients with schizophrenia from a Latin-American cohort, to explore the timing of emergence of treatment resistance and possible subgroup differences...

Glucocorticoids can have psychosis as a potential side effect, but have also been suggested to yield protective effects due to anti-inflammatory properties. Nonetheless, knowledge is sparse on the association between glucocorticoid treatment and development of psychosis, which we aimed to study in this first large-scale longitudinal study. Among all individuals born in Denmark 1995-2003 (n=597,257), we compared individuals who had redeemed ≥1 prescription for glucocorticoids to an active comparator group and a non-exposed group concerning subsequent development of schizophrenia spectrum disorders until 2013...

BACKGROUND: The superior efficacy of clozapine in treatment resistant schizophrenia has been clearly demonstrated, yet there are often delays in the commencement of clozapine. In this study, we aimed to determine; the proportion of young people with a first episode of psychosis (FEP) who would be considered eligible for clozapine treatment, the theoretical delay in commencing clozapine and to compare the outcomes of those treated with clozapine to those who were eligible but not treated with clozapine...

AIM: Early intervention programmes for first episode psychosis (FEP) aim to reduce the duration of untreated psychosis (DUP) and improve functional outcomes. The sustained maintenance of improved outcomes depends largely on patients' adherence to prescribed treatment. This paper examines the prevalence of non-adherence in a cohort of patients with FEP and the sociodemographic and clinical factors associated with non-adherent behaviour. METHODS: The sample included consecutive patients accepted from 2007 to 2012 into the Early Psychosis Intervention Programme (EPIP) in Singapore...

BACKGROUND AND AIMS: To review early case reports and experimental inductions of amphetamine and methamphetamine psychosis, prior to the prohibition of these drugs, to gain a better understanding of the nature and aetiology of methamphetamine psychosis. METHODS: Papers considered were historical case reports and case series of psychosis relating to the use and misuse of prescription amphetamine, focusing upon papers by Young & Scoville (1938), Connell (1958), and three subsequent experimental studies published in the early 1970s (Griffith 1972, Angrist & Gershon 1970 and Bell 1973), where psychosis was induced in volunteers using high-dose amphetamine and methamphetamine...
