Abstract

The Transcranial Direct Current Stimulation (tDCS) can improve or impair the function of the brain. The visual memory impairment, as one of the etiological assumptions, has been classified among a wide range of mental disorders such as Obsessive Compulsive Disorder (OCD). The present study was carried out to determine the influence of single-session anodal tDCS on visual memory of patients suffering from (OCD(. Materials & Methods: The statistical population of this research included 25 patients with OCD referred to Counseling and Mental Health Services Center of Azarbaijan Shahid Madani University in 1396. Their disorder was confirmed by psychiatrist, clinical psychology, and the Maudsley Obsessive- Compulsive Inventory (MOCI). They were organized into two groups and received two types of sham and real single-session anodal stimulation on OZ area, with cathode stimulation of 2 am on OFC for 20 minutes in 10 sessions. Results: The results obtained by multivariate analysis of covariance revealed that applying singlesession anodal tDCS influenced visual memory of patients suffering from OCD, and led to a significant difference between the experimental and sham groups. Conclusion: The findings of the study indicated that the protocol of applying single-session anodal tDCS has a potential capability to improve the visual memory of OCD patients because it increases the Cortical Stimulation and changes and regulates the Occipital Lobe which plays a crucial role in visual processing
