Objectives: This study will recruit youth with chronic tics. Chronic tics are the most common movement disorder in children. The goal of the study is to learn how the brain and environment influence children's ability to suppress tics. Specifically, we want to learn how tics are influenced by a certain part of the brain called the supplementary motor area (SMA). This part of the brain is thought to be more active in people with tics. This will be the first study to look at the relationship between SMA, tic suppression, and urges to tic. Research Procedures: The study will take place over the course of three days within a week (about 5 hours total). The study will examine the relationship between the SMA and tic suppression using a non-invasive medical technology called Transcranial Magnetic Stimulation (TMS). Participants will have a diagnostic interview, MRI brain scan (used to find the location of the SMA), and TMS. Participants will be asked to try to suppress tics before and after TMS. The information that will be collected from participation includes information about tic symptoms, emotional and behavioral functioning, and brain activity (from MRI brain images and TMS results).
