objective: electrophysiological studies have identified abnormal oscillatory activities in the cerebral cortex in schizophrenia and mood disorders. biological and pathophysiological evidence suggests specific deficits in serotonin (5-ht) receptor function in schizoaffective disorder (sa), a clinical syndrome with characteristics of both schizophrenia and bipolar disorder. this study investigate...

BACKGROUND Cognitive impairments are well-established features of schizophrenia, but there is ongoing debate about the nature and degree of cognitive impairment in patients with schizoaffective disorder and bipolar disorder. We hypothesized that there is a spectrum of increasing impairment from bipolar disorder to schizoaffective disorder bipolar type, to schizoaffective disorder depressive typ...

Cognitive studies of patients with Schizoaffective Disorder typically indicate that the cognitive function of these patients resembles that of patients with Schizophrenic Disorder more than it does patients with nonpsychotic Mood Disorder. In this study patients with Schizoaffective Disorder were compared with patients with Paranoid, Undifferentiated and Residual clinical subtypes on a number o...

OBJECTIVE Clinical outcome studies of schizoaffective disorder patients have yielded conflicting results. One reason is the heterogeneity of samples drawn from the schizoaffective disorder population. Here, we studied schizoaffective disorder patients who showed marked functional impairment and continuous signs of illness for at least 6 months (i.e., DSM criteria B and C for schizophrenia). M...

UNLABELLED Schizoaffective disorder currently raises several questions, one of them being related to the stability of the clinical diagnosis over time. The aim of this study is to identify the clinical and evolutional particularities in the longitudinal course of schizoaffective disorder. MATERIAL AND METHODS 44 subjects with a current diagnosis of schizoaffective disorder have been assessed ...

BACKGROUND Biomarkers are needed that can distinguish between schizophrenia and schizoaffective disorder to inform the ongoing debate over the diagnostic boundary between these two disorders. Neuromorphometric abnormalities of the thalamus have been reported in individuals with schizophrenia and linked to core features of the disorder, but have not been similarly investigated in individuals wit...

Abstract Objective: The effect of metformin on weight changes and some metabolic parameters in patients with schizophrenia and schizoaffective disorder was investigated in this study. Methods:  This study, performed during 2018-2019, was a randomized, double-blind, controlled clinical trial. A total of 66 obese patients (BMI≥27) with schizophrenia and schizoaffective disorder, hospitalized in...

INTRODUCTION Despite being frequently diagnosed, there has been very limited study of efficacious treatments for schizoaffective disorder. Paliperidone had been approved for the treatment of schizoaffective disorder, and a recently completed relapse prevention study of the use of a once-monthly injectable paliperidone formulation has also led to an indication for that preparation to treat schiz...
