OBJECTIVE: To evaluate durability of therapeutic effect of long-term treatment with aripiprazole lauroxil in patients with schizophrenia following successful treatment of an acute psychotic episode. METHODS: This post hoc analysis assessed long-term outcomes for a subgroup of patients who entered a 52-week extension study after being successfully stabilized with one of 2 doses of aripiprazole lauroxil (441 or 882 mg) in a pivotal 12-week, placebo-controlled, randomized clinical trial...

Depressive episodes or symptoms occur frequently in patients with schizophrenia and may have far-reaching consequences. Despite the high prevalence rate and clinical relevance of this comorbidity, knowledge about treatment options is still limited. The aim of this review is to provide an overview of the literature concerning treatment options for depressive episodes or symptoms in schizophrenia. Based on the current evidence, we present a stepwise treatment approach. The first step is to evaluate the current antipsychotic treatment of psychotic symptoms and consider lowering the dosage, since increased blockade of the dopamine D2 receptors may be associated with a worse subjective sense of well-being and dysphoria...

Dopamine supersensitivity psychosis (DSP) is observed in patients with schizophrenia under antipsychotic treatment, and it is characterized by rebound psychosis, an uncontrollable psychotic episode following a stable state and tardive dyskinesia. DSP, first described in patients taking typical antipsychotics in the late 1970s, sometimes appears even in patients who are treated with current atypical antipsychotics. It was recently demonstrated that DSP can have a negative impact on the long-term prognosis of schizophrenia patients and that DSP could be involved in the etiology of some cases of treatment-resistant schizophrenia...

Both post-mortem and neuroimaging studies have identified abnormal white matter (WM) microstructure in patients with schizophrenia. However, its genetic underpinnings and relevant biological pathways remain unclear. In order to unravel the genes and the pathways associated with abnormal WM microstructure in schizophrenia, we recruited 100 first-episode, drug-naïve patients with schizophrenia and 140 matched healthy controls to conduct genome-wide association analysis of fractional anisotropy (FA) value measured using diffusing tensor imaging (DTI), followed by multivariate association study and pathway enrichment analysis...

BACKGROUND: Long-acting antipsychotic therapy may be best suited for patients in the early stage of schizophrenia, when the most can be done before disease progression associated with poor adherence occurs. We explored the patterns of use of once-monthly paliperidone palmitate (PP1M), concomitant medication use, hospitalization, and clinical outcomes of adult, newly diagnosed patients with schizophrenia receiving continuous treatment with PP1M for at least 12 months. METHODS: This was an international, multicenter, exploratory, retrospective chart review of medical records of adult patients who were newly diagnosed (not more than 1 year before initiation of PP1M treatment) with schizophrenia and who had received continuous treatment with PP1M for ≥12 months in naturalistic clinical settings...

Cognitive impairment is a core feature of psychosis, with slowed processing speed thought to be a prominent impairment in schizophrenia and first-episode psychosis. However, findings from the Stockings of Cambridge (SOC) planning task suggest changes in processing speed associated with the illness may include faster responses in early stages of planning, though findings are inconsistent. This review uses meta-analytic methods to assess thinking times in psychosis across the available literature. Studies were identified by searching PubMed, Web of Science and Google Scholar...

BACKGROUND: Schizophrenia is characterized by abnormal perception, thinking, emotions, and behaviors. Cognitive dysfunction is acknowledged as one of the most pivotal symptoms in schizophrenia. In addition to positive or negative symptoms, which had been proposed by Gallhofer in the early 1970s, schizophrenia patients suffered from cognitive impairments as well. Many studies show that there is genetic susceptibility in the first grading kinship of patients with schizophrenia. Patients with schizophrenia have cognitive impairment not only in the acute phase but also in the stable phase...

Motor abnormalities (MAs) are highly prevalent in patients with first-episode psychosis both before any exposure and after treatment with antipsychotic drugs. However, the extent to which these abnormalities have predictive value for long-term psychosocial functioning is unknown. One hundred antipsychotic-naive first-episode psychosis (FEP) patients underwent extensive motor evaluation including catatonic, parkinsonism, dyskinesia, akathisia and neurological soft signs. Patients were assessed at naïve state and 6months later...

Past studies have linked intracellular pathways related to psychotic disorders to the GSK3B enzyme. This study aimed to investigate GSK3B protein expression and phosphorylation in drug-naïve first-episode psychosis patients (n=43) at baseline and following symptom remission, and in healthy controls (n=77). At baseline GSK3B total level was higher in patients (p<0.001). In schizophrenia spectrum patients (n=25) GSK3B total and phosphorylated levels were higher than in controls and patients with other non-affective psychotic disorders (n=18) (p<0...

Spectral entropy (SE) is a measurement from information theory field that provides an estimation of EEG regularity and may be useful as a summary of its spectral properties. Previous studies using small samples reported a deficit of EEG entropy modulation in schizophrenia during cognitive activity. The present study is aimed at replicating this finding in a larger sample, to explore its cognitive and clinical correlates and to discard antipsychotic treatment as the main source of that deficit. We included 64 schizophrenia patients (21 first episodes, FE) and 65 healthy controls...

The memory impairment is a core deficit in the first-episode schizophrenia patients. Arginine vasopressin (AVP) in the brain can improve learning and memory. We performed multicentre, randomized, double-blind, placebo-controlled, parallel-group clinical trial to study the cognitive functioning in Han Chinese first-episode schizophrenic patients in a 12-week treatment regime with the intranasal administration of AVP (128 cases) or placebo (131 cases) in addition to the conventional treatment. The methods of positive and negative syndrome scale (PANSS), Wechsler memory scale-4th edition (WMS-IV) and event-related potential (ERP) were used to study the effects of AVP on the cognitive function...

AIM: While the course of psychopathology has been explored from an index mental health diagnosis onwards, there are few detailed, prospective studies of the occurrence of clinical psychopathology in youth with familial risk for severe mental illnesses such as psychosis. We sought to describe the appearance of Axis I psychopathology in a unique sample of adolescents with a family history of schizophrenia (FHR). METHODS: One hundred and sixty two first- and second-degree relatives (mean age 15...

Evidence indicates that schizophrenia and in particular negative symptoms and deficit schizophrenia are accompanied by neurocognitive impairments and changes in the patterning of the tryptophan catabolite (TRYCAT) pathway. This cross-sectional study was carried out to examine the associations between cognitive functions (as measured with Consortium to Establish a Registry for Alzheimer's disease (CERAD)) and TRYCAT pathway patterning in patients with (n = 40) and without (n = 40) deficit schizophrenia and normal controls (n = 40)...

BACKGROUND: When treatment-refractory schizophrenia shows an insufficient response to a trial of clozapine, clinicians commonly add a second antipsychotic, despite the lack of robust evidence to justify this practice. OBJECTIVES: The main objectives of the study were to establish the clinical effectiveness and cost-effectiveness of augmentation of clozapine medication with a second antipsychotic, amisulpride, for the management of treatment-resistant schizophrenia...

EDITORIAL
Stefan Leucht, John M Davis
There is a debate about long-term treatment of schizophrenia with antipsychotic drugs, with some experts suggesting that these drugs should be discontinued. In this issue, Takeuchi et al demonstrated by a meta-analysis of 11 trials that antipsychotic drugs maintained their efficacy for relapse prevention for 1 year, whereas patients on placebo kept getting worse. We consider these findings in the light of the current discussion about possible dose-related brain volume loss, supersensitivity psychosis, the high variability of results in long-term follow-up studies and recent approaches to discontinue antipsychotics in patients with a first-episode...

Specialized First Episode Psychosis (FEP) services have been conceptualized in part around the issue of engagement. Creating treatment that is easier to access, with more frequent contacts, assertive outreach to clients between appointments, and an explicit youth-oriented culture could make services more attractive to those most in need of care. However, engagement has remained a mostly fuzzy, peripheral construct rather than the object of study in itself. As we recognize the importance of treatment engagement, we must prepare to address it more rigorously within psychosis and schizophrenia research...

The current study aimed to explore age-variant trait differences of cortical gray matter volume (GMV) in a unique sample of first-episode and treatment-naïve patients with schizophrenia. A total of 158 subjects, including 26 adolescent-onset patients and 49 adult-onset patients as well as 83 age- and gender-matched controls were scanned using a 3T MRI scanner. Voxel-based morphometry (VBM) following Diffeomorphic Anatomical Registration Through Exponentiated Lie algebra (DARTEL) was used to explore group differences between patients and controls in regional GMV...

AIM: Higher-order language functions are associated with understanding indirect speech acts, lexical-semantic processes, the understanding and production of prosody, discourse production and comprehension. Only a few studies imply that language abnormalities may be present in individuals at ultra-high risk for psychosis (UHR) and first-episode of schizophrenia (FE). The purpose of this study was to test the presence of higher-order language dysfunctions in UHR and FE subjects using a standardized comprehensive test battery...
