? 2022 Elsevier LtdObjective: Deep brain stimulation (DBS) is considered a promising intervention for treatment-resistant obsessive–compulsive disorder (OCD). The present study describes the outcomes of the first DBS procedures for OCD in Iran. Methods: Four women patients (age range, 25–35 years) with severe OCD meeting stringent criteria for refractoriness to treatment were selected by Psychosurgery Review Board. DBS electrodes were bilaterally implanted in the internal capsule and nucleus accumbens (NAc). Clinical and neuropsychological assessments were undertaken before and after implantation. The outcomes included Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Hamilton Anxiety Rating Scale (HAM-A), neuropsychological assessments including the Wisconsin Card Sorting Test, Wechsler Memory Scale, and adverse events. Results: The baseline mean score of the Y-BOCS and HAM-A was 32 ± 6 and 23 ± 14 respectively and decreased to 26 ± 8 and 17 ± 9 after one-year implantation, showing a 19% improvement. Two patients were responders and showed a notable improvement. One patient's score declined 28%, who was not satisfied with DBS results, and one patient worsened under-stimulation. Improvements in the severity of anxiety and cognitive performance were consistent with OCD improvement, and the successfully treated patients showed improvement in anxiety and cognitive performance. No significant cognitive declines were seen. Two patients' suicidal ideation appeared after DBS as an important adverse event. Conclusion: Bilateral DBS of the internal capsule/NAc may be an effective and safe treatment for treatment-refractory OCD. However, there is a need to consider accessibility, high cost, cost-effectiveness, and standardized methodology in future research.
