Abstract

Recent study suggests that OCD and MD patients show cognitive and neuropsychological deficits, but some researchers suggest that neuropsychological deficits in OCD, is due to depression comorbidity. Therefore present study, try to investigate this hypothesis that obsessive-compulsive and depressive subclinical patients are different in three components of executive function (inhibition, set shifting and updating of working memory)? To this aim, after screening with SCL-90, 30 depressive and 30 obsessive-compulsive subclinical patients were selected and compared with 30 control healthy subjects. Beck depression Inventory and Maudsley Obsessive-Compulsive Inventory were used to diagnose subjects. OCD subjects that took above score 20 in Beck depression inventory excluded from study.
Data analysis showed that there was significant difference between control with OCD and MD groups in inhibition. Also there was significant difference between OCD and MD groups, and severity of deficits in MD was more than OCD people. In set shifting, there was significant difference between control and other two groups, but severity of deficits in MD was more than OCD too. In third dimension, updating, there was significant difference between two patients and control groups, but MD and OCD was similar in deficits.
At all, present study finding suggest that both subclinical MD and OCD patients showed deficits in three components of executive function, but MD patients show more deficits in executive function.
