Summary: Community Health Workers will go door-to-door in Carrefour, Haiti to look for symptoms of Tourette Syndrome (TS) and chronic tic disorder (CTD) in adults, aged 18 to 65, using a study-specific video screener. Participants will be videotaped while taking the computerized assessment and these videos will be sent to specialists in the US to confirm current symptoms. Results will help determine the true prevalence in this population and whether or not current estimates of prevalence are the result of biased diagnosis and reduced access to treatment, or if they reflect a real difference in prevalence in populations of African descent.
