Positive psychotic symptoms, such as threat/"control-override" delusions or command hallucinations, have been related to aggression in patients with schizophrenia. However, retrospective data collection has hampered evaluation of the direct influence of psychopathology on aggressive behavior. In this study, we monitored aggressive behavior and psychopathology prospectively and in close temporal...

This study compared two measures of depression in a population with schizophrenia. Inpatients (n = 112) with schizophrenia, were assessed on the Hamilton (HDRS), and Calgary (CDSS) depression scales and the Positive and Negative Syndrome Scale (PANSS). Eighty-nine were reassessed 3 months later. A principal components factor analysis was applied to each depression scale. The relationship betwee...

BACKGROUND The objective of this study was to examine the cross-cultural differences of the PANSS across six geo-cultural regions. The specific aims are (1) to examine measurement properties of the PANSS; and (2) to examine how each of the 30 items function across geo-cultural regions. METHODS Data was obtained for 1,169 raters from 6 different regions: Eastern Asia (n = 202), India (n = 185)...

OBJECTIVE Inflammatory processes may play a role in the pathophysiology of schizophrenia. The aim of this study was to determine the efficacy of adjuvant treatment with aspirin (acetylsalicylic acid) in schizophrenia spectrum disorders. METHOD This randomized, double-blind, placebo-controlled study was conducted between May 2004 and August 2007. Seventy antipsychotic-treated inpatients and ou...

background: the purpose of this study was to test the hypothesis that the addition of buspirone, a partial agonist of 5ht1a receptor, to ongoing treatment with typical antipsychotics would improve the positive and negative symptoms in patients with chronic schizophrenia. materials and methods: in this study, 50 patients including 40 male and 10 female were recruited with chronic schizophrenia w...

Introduction Olanzapine (OLA) is a common first-prescribed antipsychotic and has shown favorable efficacy in acutely exacerbated patients with schizophrenia. The mixed receptor activity of OLA its greater affinity for serotonin 5-HT2A rather than dopamine D2 receptors are similar to those clozapine. Pharmacokinetically, metabolized mainly by hepatic cytochrome enzyme P450 1A2 (CYP1A2). Because ...

OBJECTIVES In the last decade there have been numerous randomized controlled trials comparing the efficacy and safety of second generation antipsychotics and conventional antipsychotics in the treatment of schizophrenia, but most of them have been conducted in the western population. This study compared the efficacy and safety of risperidone versus haloperidol in the Nepalese context, in order ...

BACKGROUND Effective management strategies for the negative symptoms of schizophrenia remain an unmet need, and data on the use of antipsychotics in this population are scarce, particularly in Chinese patients. Therefore, we investigated amisulpride for the treatment of Chinese patients with predominantly negative symptoms of schizophrenia. METHODS This post hoc subanalysis of the prospective...

objective : poor premorbid adjustment has been reported to be a predictor of more severe psychotic symptoms and poor quality of life in such psychotic disorders  as  schizophrenia.  however,  most  studies  were  performed  on chronic schizophrenic patients, and proposed the likelihood of recall biases and the effect of chronicity.  the aim of this study was to investigate these factors in a sa...

There are diverse studies which afford evidences that risperidone is as effective second generation antipsychotics in treating positive symptoms and more treatment of negative symptoms. This study intended to find the clinical efficacy safety profile lurasidone comparing with risperidone, a drug common use nowadays. Patients aged between 18 60yrs, new onset who fulfil ICD-10 criteria for primar...
