Protocol summary

Study aim
Investigation of Deep Brain Stimulation for Treatment of Refractory Obsessive-Compulsive Disorder patients and their neuropsychological performance
Design
A study on 5 Refractory Obsessive-Compulsive Disorder patients
Settings and conduct
Before implantation the severity of OCD, Personality, and cognition of patient will be evaluated. The electrodes will be surgically bilateral implanted in the nucleus accumbens in Rasoul Akram Hospital, Iran University of Medical Sciences. Patients will receive stimulation and all outcomes will be recorded in 1 and 2 weeks after implantation. in addition, the outcomes will be recorded in every 1 month for 12 months follow up in school of Behavioral Sciences and Mental Health.

Description
Deep brain stimulation (DBS), a neurosurgical procedure involving the implantation of a medical device called a neurostimulator, which sends electrical impulses, through implanted electrodes, to specific targets in the brain (nucleus accumbens) and stimulate this nucleus. After surgery, stimulation will be 130 Hz, at pulse widths of 90 and 150 us and at 2–7 V. Stimulation will adjust in optimization phase base on improvements of patients and clinical outcomes.
