This was a study of children ages 5-10 who were experiencing a recent onset of tics, and comparison children with Tourette syndrome or with no tics. The purpose of this research was to compare children who would go on to develop Tourette Syndrome with children whose tics would resolve.

Enrollment is now closed. Thank you to all our participants for making this study possible! If you are a past or current participant and have a question, please contact our research staff at 314-273-7575.
