Impact of negative symptoms on health-related quality of life in schizophrenia.

Evidence regarding the association of Negative Symptoms (NS) dimensions with Health-related Quality of Life (HRQoL) is limited and no prior study has looked into contributions of NS domains on HRQoL. This study bridges the gap by examining the associations of NS, its two dimensions (Motivation and Pleasure, and Emotional Expressivity) and five domains (Anhedonia, Avolition, Asociality, Blunted affect and Alogia) with HRQoL in schizophrenia. 274 individuals with schizophrenia were assessed on the Positive and Negative Syndrome Scale (PANSS) and Brief Negative Symptom Scale (BNSS).

Impact of Cognitive Impairments on Health-Related Quality of Life in Schizophrenia.

The impact of cognitive impairments on the health-related quality of life (HRQoL) in individuals with schizophrenia is unclear. The aim of this study was to examine the association between cognitive impairments and HRQoL in individuals with schizophrenia. A total of 609 individuals with schizophrenia were assessed on the Positive and Negative Syndrome Scale (PANSS) and a neurocognitive battery which comprised of the Wechsler Abbreviated Scale of Intelligence matrix reasoning, the Benton Judgment of Line Orientation Test, Continuous Performance Tests-Identical Pairs, and the Brief Assessment of Cognition in Schizophrenia.

Metabolic syndrome and cardiovascular risk between clozapine and non-clozapine antipsychotic users with schizophrenia.

Introduction: Clozapine use is associated with higher risks of metabolic side effects and cardiovascular diseases (CVD). Thus, this study aims to establish and compare the cardiometabolic profiles between non-clozapine antipsychotic and clozapine users with schizophrenia.

Methods: Data from 88 non-clozapine and 166 clozapine users were extracted from existing databases - demographics, medications, smoking and medical histories, anthropometric parameters, serum lipid and fasting glucose levels.

Defining negative symptoms remission in schizophrenia using the Brief Negative Symptom Scale.

Introduction: This study aimed to propose criteria for negative symptoms remission (NSR) in schizophrenia using the Brief Negative Symptom Scale (BNSS).

Material And Methods: 274 participants were assessed on the Positive and Negative Syndrome Scale (PANSS), BNSS and Social and Occupational Functioning Assessment Scale (SOFAS). Two criteria for NSR on the BNSS were proposed - NSR based on the BNSS domains scores (NSR) and NSR based on 5 key items of the BNSS (NSR) A SOFAS score of 61 and above was considered as functional remission (FR).

Impact of drug-induced Parkinsonism and tardive dyskinesia on health-related quality of life in schizophrenia.

Background: Both drug-induced Parkinsonism (DIP) and tardive dyskinesia (TD) have been shown to be associated with lower health-related quality of life (HRQOL) in schizophrenia, but few studies have examined their relative impact.

Aims: This study aimed to examine and compare the association of DIP and TD with HRQOL in schizophrenia.

Methods: In total, 903 patients with schizophrenia were assessed on the Positive and Negative Syndrome Scale (PANSS), Simpson-Angus Scale (SAS), and Abnormal Involuntary Movement Scale (AIMS).
