OCD Stats & Science

Nearly everyone has heard of OCD, but few truly understand what it is: a potentially debilitating mental illness that consumes people with fear and doubt, often about the things that matter the most to them. Instead, OCD is frequently portrayed as nothing more than a personality quirk in popular media, causing millions to suffer in silence, unaware that their struggle has a name.

Despite prevailing misconceptions and stigma, we actually know a lot about the condition and how it can be properly managed, as OCD has been studied and treated effectively for decades. Unfortunately, most people don’t have access to the right information.

We want to redefine the way OCD is understood around the world by providing accurate, high-quality information from experts in OCD research and treatment. Browse articles covering a wide range of topics in the science and statistics of OCD, from brain chemistry to effective treatment interventions.
