This white paper represents the largest study on OCD conducted in the US. The findings are striking: an overwhelming number of individuals with OCD are being undiagnosed or misdiagnosed by healthcare professionals. Even with a diagnosis, an astonishing treatment gap emerges, with a near total failure to provide, or even recommend, gold standard, evidence-based OCD therapy. Up to 10 million Americans live with OCD, yet only 1 in 6 receive a correct diagnosis. As a result, 95% of people in the US with OCD do not receive the most effective treatment, despite strong evidence that specialized therapy can significantly reduce symptoms and restore daily functioning. The white paper shares insights on the factors contributing to this issue as well as recommendations to help address them locally and nationally.
