Once believed to be rare, OCD was found to have a lifetime prevalence of 2.5% in the Epidemiological Catchment Area study. [1] Current estimates of lifetime prevalence are generally in the range of 1.7-4%. Discovery of effective treatments and education of patients and health care providers have significantly increased the identification of individuals with OCD. The incidence of OCD is higher in dermatology patients and cosmetic surgery patients.
