Recruitment of participants has now resumed. We are inviting adults with #OCD (or who suspect they have OCD), siblings of people with OCD, and people without OCD to rise to the challenge of taking part and making a difference.
Global OCD

The Global OCD international multisite study investigates how the brains of people with obsessive-compulsive disorder (OCD) work. The project was launched early in 2018, and will be conducted over a period of approximately 5 years.

We are following strict COVID-19 guidelines.
Participation is voluntary, cost-free, and could include a brain scan.


Take Part

Individuals with OCD, and siblings of individuals with OCD, and controls, between the ages of 18 and 50 years, who are physically healthy, and not taking psychotropic medications, are invited to take part.
