Comparison of cognition and alexithymia in patients of schizophrenia with and without comorbid alcohol use: A cross-sectional exploratory study

Abstract

Background: Cognitive impairment and alexithymia are commonly associated with schizophrenia and alcohol use disorder independently. Both can lead to poor prognosis and recovery. In patients with dual diagnosis, this association can be more prevalent and severe. Materials and Methods: A total of 75 participants were grouped into two (35 each): Group A, a Schizophrenia group and Group B with comorbid alcohol use. Sociodemographic factors, clinical profile, cognitive functions, and alexithymia were compared between the two groups using semi-structured pro forma, Positive and Negative Syndrome Scale, Alcohol Use Disorders Identification Test (AUDIT), Montreal Cognitive Assessment (MoCA) Scale, Toronto Alexithymia Scale (TAS-20) (subcategorized into three subscales (1) “Difficulty describing feelings” (DDF), (2) “Difficulty identifying feeling” (DIF), and (3) “Externally-Oriented Thinking” and Brief Psychiatric Rating Scale. Statistical analysis was performed using the Chi-square tests and t-tests as applicable. P 8 (P < 0.05). Lower score on MoCA correlated with the higher score of alexithymia. Conclusion: Cognitive dysfunction and alexithymia were significantly more in patients of schizophrenia with comorbid alcohol use and positively correlated with the severity of alcohol use disorder.
