Dr. Kevin Black (Washington University, St. Louis) is conducting a study with children between the ages of five and 14 who are experiencing a recent (past three months) onset of “tics” — repetitive, involuntary sounds or movements such as eye blinking, sniffing, abdominal tensing or making small noises.

The purpose of the research is to compare children who go on to develop Tourette Syndrome (TS) with those who do not.

Participants are required to make four visits over approximately 12 months. Compensation is available.
