The Use of Transcranial Ultrasound Treatment of Obsessive-Compulsive Disorder

The present study is being undertaken as an open-label study to evaluate the safety and feasibility of focused ultrasound as an intervention for patients with obsessive compulsive disorder (OCD). Participants in this study will undergo 8 consecutive weekly sessions of transcranial low-intensity focused ultrasound (LIFUP) targeting the caudate of the basal ganglia. The safety of this protocol will be closely monitored and data will be used to determine whether any significant safety issues exist when using focused ultrasound for this neurological application. Treatment response will be measured using the Beck Depression \& Anxiety Inventories, the Yale-Brown Obsessive-Compulsive Scale, and the Global Rating of Change Scale.
