Obsessive Compulsive Disorder (OCD) Research Clinic

Obsessive-compulsive disorder (OCD) is a common and frequently debilitating psychiatric disorder that often goes undiagnosed and undertreated. The Yale OCD Research Clinic has a 25-year history of advances in the neurobiological understanding and treatment of this condition. Our current work, funded by the National Institute of Health, the Doris Duke Charitable Foundation, and other groups, continues this tradition, as we seek to better understand the brain processes that have gone awry in OCD and to use this knowledge to develop new treatments.

If you are interested in volunteering for a study at the Yale OCD Research Clinic, you can find contact information and other details in the ‘Participate’ section of this site. We have studies appropriate for both medication-free patients and those who have already tried medication or psychological treatment but continue to have significant symptoms. Anyone who seems appropriate for our studies after an initial phone conversation receives an evaluation, free of charge, from one of the Clinic’s psychiatrists; we are often able to make recommendations regarding medication and other treatment, even if you do not participate in a research study.

Our studies are for participants age 18 and up. Those under 18 are referred to the Yale Child Study Center's clinic

Please note that we are not able to provide treatment services. If you are looking for more information on OCD and treatment providers in your area, the International Obsessive-Compulsive Foundation may be a useful resource.
