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.

Dr. Kevin Black, M.D., is conducting a study with children ages 5-10 who are experiencing a recent onset of tics, and other, control children. The purpose of this research is to compare children who go on to develop Tourette Syndrome with children whose tics will resolve.

Tics are repetitive, involuntary sounds or movements like eye blinking, sniffing, abdominal tensing or making small noises.

Many children with ADHD (20-50%) also have tics, even if they haven’t noticed them.

Previously seeking:

Children, ages 5-10, right-handed, who have been diagnosed with Tourette Syndrome or a Chronic Tic Disorder.

Children, ages 6-9, right or left handed, who have been diagnosed with ADHD but NOT Tourette Syndrome or a Chronic Tic Disorder.

Who may qualify for this study?

  • Children ages 5-10 years old with parent/guardian participation
  • Children with tics that started less than 12 months ago
  • Children with Tourette syndrome or chronic tics
  • Children without tics who have ADHD

What does participation include?

  • Up to 6 visits, including annual follow-ups
  • Compensated up to $100 per visit.
  • MRI scans, interviews, questionnaires & DNA sample
  • Study procedures are provided at no cost to you
