Researchers at CAMH are looking for individuals aged 18 to 50 years old who experience obsessions and/or compulsions OR diagnosed with obsessive-compulsive disorder. We will use brain imaging techniques (PET: positron emission tomography and MRI: magnetic resonance imaging) to observe and study whether an important brain network contributes to OCD. This will help us learn more about the biological mechanisms of this condition and also potentially guide development of new treatment options.
