Study Summary

This trial is to study the safety and feasibility of using a technology called Low Intensity Focused Ultrasound (LIFU) to treat patients with obsessive-compulsive disorder (OCD). The device is used to send high frequency sound waves to a particular region of the brain called the Ventral Striatum (VS). LIFU is a non-invasive form of stimulation, which can be used to stimulate deep regions of the brain. The trial will last two weeks with three weekly treatment sessions.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Acute changes in domains of mood, anxiety, alertness in response to VS LIFU after each sonication session as assessed by the Likert scale.
Magnetic Resonance Imaging
Primary study endpoint for OCD severity will be change in Y-BOCS score after 6 sonication sessions compared to baseline.

Experimental Treatment
Group I: LIFU in OCD groupExperimental Treatment1 Intervention
Each subject will receive 3 LIFU sessions epr week for two weeks (6 total image-guided treatments). A total of 20 sonications will be administered to one side of the head, with a derated (based on FDA standard of 0.3 dB/cm-MHz) spatial-peak temporal-average intensity (i.e., Ispta) of approximately 720mW/cm2, each lasting 30 s, separated by 30 s pause intervals. Thus, total duration of sonication will be 10 minutes, the same as used in our study of VS LIFU in healthy subjects. Sonication will be administered within a 3T Siemens Prisma scanner. During sonication, we will use the 20-channel head coil as the 32-or 64-channel coil does not allow enough space to fit the transducer. In summary, the entire sequence of 20 sonications, each lasting 30s, separated by 30s pause intervals, will be administered over 20 minutes for a total duration of sonication equal to 10 minutes.
