Assessment of various cognitive domains in patient with obsessive-compulsive disorder

Background: OCD is often chronic disorder and causes impairment of functional efficiency. Various researchers have found that cognitive dysfunction frequently present even when mild symptoms are present. This study aimed to investigate various domains of cognitive function in patients with OCD using cross sectional design. In this study we have tried to find out the various domains of cognitive function in OCD and their relation with clinical severities. We also compared the cognitive function of patients with OCD and their control. Methods: Total 60 subjects (30 in case group and 30 in control group) were taken for study. The study subjects (OCD group) were taken from psychiatric OPD and control group from general populations. The subjects of both the groups were screened as per inclusion and exclusion criteria and the Y-BOCS, ACE –III scales were applied. Results: In the case group, 96.70% had a normal ACE-III score and 3.30% had an inconclusive score, while in the control group 100% had a normal score at ACE-III scale, on further scoring. 60% patients have moderate and 33.3% have severe score in the YBOCS scale. We have found the significant decline in total mean ACE-III scores between case and control group (p value 0.000) and decline in memory domain with severity of illness was also significant (p value 0.037). Conclusions: Decline in cognition domain of memory in patient with OCD, was significant in comparison to control group.
