Journal Title: INDIAN JOURNAL OF MENTAL HEALTH - Year 2019, Vol 6, Issue 1
Abstract
Background and Objectives: OCD is one of the most debilitating psychiatric conditions with complex etiopathological profile causing interference with a wide range of social and cognitive demands. NeuroPsychological and neuro-imaging studies on OCD patients have implicated that the frontal cortex and subcortical structures are involved in this disorder and testing has revealed evidence of impairment in visuospatial abilities, non-verbal memory and executive function. To evaluate cognitive impairment in Obsessive Compulsive Disorder patients. Methods:Thirty patients who presented to Psychiatry Department of Dayanand Medical College and Hospital, Ludhiana with diagnosis of OCD as per ICD-10 were taken up for the study. Cognitive impairment was assessed using PGI brain dysfunction battery designed for Indian population by Dwarka Pershad and Santosh K. Verma (3 edition 2015). PGI brain dysfunction battery is a measure of cognitive impairment consisting of: Verbal Adult intelligence scale, Revised Bhatia short battery of performance tests of intelligence, PGI memory scale, Nahor Benson test, Bender Visuo-Motor Gestalt test. Those patients who had any major medical disorder or any other Psychiatry disorder on AXIS-I were excluded from the study. Results: In the present study, dysfunction was noticed in areas of immediate recall ,abstract thinking, arithmetical ability in verbal intelligence subscale and in visuo-motor coordination. These all areas are executive functions of frontal lobe. This shows that OCD patients are having difficulty in calculations due to interference of the obsessive symptoms, though their attention and concentration were found intact. Visuo-motor coordination problem may be due to compulsive tendency due to which overlap, perseveration and partial rotation were found dysfunctional. Conclusion: Since OCD is highly distressing to the patient, the superadded cognitive dysfunctions such as memory impairment, abstract thinking, impairment in visuo-motor coordination further worsens the outcome of the illness. So, early identification of these dysfunctions would provide considerable benefit to the patients.
