Recruitment of participants has now resumed. We are inviting adults with #OCD (or who suspect they have OCD), siblings of people with OCD, and healthy individuals 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 in comparison to the brains of healthy individuals. 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.
