We are currently enrolling treatment studies on Obsessive Compulsive Disorder (OCD), please see below. Additionally, we frequently develop new research studies and have created a Volunteer Research Registry to keep people updated on studies for which they might be eligible. If you would like to be contacted about any new research studies, please complete the Volunteer Research Registry.

Transcranial Direct Current Stimulation potentiation of fear extinction in OCD: Towards rational design of combination therapies
PI: Joan A. Camprodon, M.D, M.P.H, Ph.D.
Purpose of the study: People with OCD struggle with recurrent, unwanted thoughts or images (obsessions) and/or repetitive behaviors (compulsions) that create distress in their life and for their loved ones. People with OCD often have many fears and may go to extremes to avoid the things they fear. The purpose of this research study is to learn more about how human beings learn not to fear and the impact of changing the fear network in the brain using transcranial Direct Current Stimulation (tDCS) in individuals with obsessive compulsive disorder (OCD). In tDCS, electrodes are applied to the scalp. The electrodes are attached to a machine that sends electrical current through the brain resulting in a temporary change in brain activity. The tDCS procedure will not activate any of your brain cells causing them to “fire,” however the stimulation will adjust the likelihood of some brain cells “firing” on their own.
Eligibility: We are inviting adults ages 18-60 with OCD to participate in the research study. Those interested must be fluent in English, willing to attend the two in person visits at the MGH Charlestown Navy Yard campus, and must be comfortable and capable of using a computer and completing computerized tasks.
Length of the study: 3 study visits (2-3 hours virtual, 3.5 hours in person, 2 hours in person)
Visit type: Participation includes: (1) A virtual intake assessment visit consisting of a clinical interview (2-3 hours) and self-report questionnaires (30 minutes), (2) Two in-person visits over two consecutive days at the MGH Charlestown Navy Yard campus, including: (a) a fear learning computer task in which you view a series of pictures on the computer screen; after you see some of the pictures, you will receive a half-second electric shock that it is annoying but not painful, (b) before, during, or after the computer task on Day 1 you will be randomly assigned to receive either 20 minutes of active transcranial Direct Current Stimulation (tDCS) — a noninvasive neuromodulation technique that stimulates the brain — or you will receive sham tDCS, and (c) during the computer task we will measure brain activity using an electroencephalogram (EEG) machine and skin conductance (i.e., sweatiness of your palms) using electrodes that fit comfortably on your fingers.
Payment: Participants will receive up to $300 for participating. Parking costs will also be reimbursed.
