Cognitive dysfunction and disability in people living with schizophrenia

BACKGROUND: Schizophrenia is a major mental disorder characterized by positive, negative, and cognitive symptoms. Cognitive impairment is a central and enduring feature of schizophrenia and is associated with disability. It has a devastating consequence on the individuals, families, and the society. Our aim was to assess cognitive functioning, disability, and their association with sociodemographic and illness-related variables. METHODOLOGY: In an outpatient department of psychiatry, 82 adult patients with a diagnosis of schizophrenia were recruited. Schizophrenia Cognition Rating Scale (SCoRS), Positive and Negative Syndrome Scale (PANSS), and Indian Disability Evaluation and Assessment Scale (IDEAS) were used to assess cognitive function, psychopathology, and disability respectively. Socio-demographic and illness-related details were collected using a semi-structured questionnaire. Data were analyzed using STATA version 16.0 using appropriate statistical tests. RESULTS: Approximately 93.9% of patients had at least one cognitive symptom even though not severe. The status of being married was associated with better cognitive outcome. No other socio-demographic factor was associated with cognitive dysfunction. Negative symptoms and general psychopathology scores of PANSS were positively correlated with SCoRS scores and IDEAS score. Cognitive dysfunction and disability were significantly associated suggesting higher the cognitive deficit in schizophrenia greater is the likelihood of patient experiencing disability. CONCLUSION: Cognitive deficits are commonly seen in patients with schizophrenia and are associated with disability. Therefore, treatment programs of schizophrenia should have a component to address these deficits using evidence-based cognitive remediation therapies. Family Physicians caring for those with schizophrenia should factor the cognitive deficits and simplify dosage regime and engage caregivers for supervision.
