Cognitive impairments in schizophrenia: assessment, symptom correlations, and implications for clinical management

Schizophrenia is a chronic, severe mental illness that affects cognitive functioning alongside its well-known positive and negative symptoms. Cognitive impairments, including deficits in memory, attention, executive function, and social cognition, significantly impact patients’ quality of life and independence, yet remain inadequately addressed in clinical practice. This study aims to explore the cognitive impairments in schizophrenia and their relationship with symptom severity in a cohort of 28 male inpatients diagnosed with the disorder. Cognitive function was assessed using the Addenbrooke’s Cognitive Examination III, Brief Cognitive Assessment Tool, and the Positive and Negative Syndrome Scale. The study also examined the correlation between cognitive deficits and educational level, as well as between cognitive impairment and symptom dimensions. Results showed no statistically significant correlation between cognitive deficits and educational attainment or symptom severity. This suggests that cognitive impairment in schizophrenia is multifactorial, and the current tools for assessment may not fully capture the complexity of these deficits. Despite these limitations, the study
