B-Bit, Brain Behavior in Tics

What is the study?

For adolescents who have a chronic tic disorder: verbal, motor or both (Tourette Syndrome)

Who can participate?

Adolescents between the ages of 12-18 who are diagnosed with a Tic Disorder or Tourette Syndrome are eligible to participate.

What would we do in the study?

The study involves 3 visits, all conveniently located at the University of Minnesota.

  • Visit 1 will be an assessment.
  • Visit 2 is a magnetic resonance imaging (MRI) brain scan.
  • Visit 3 involves Transcranial Magnetic Stimulation (TMS), and observation of your child's tics during different tasks. TMS is a noninvasive method that influences brain activity for several minutes. In TMS, a magnet is placed next to the head, and small electrical currents activate the brain cells underneath. TMS is painless and well-tolerated in children.

If you child has any metal or medical implants (pacemaker, metal plates or screws, etc.), has been diagnosed with Autism, has epilepsy or another seizure disorder, or has a history of traumatic brain injury, they are not eligible for the study.

You will be compensated for your time and reimbursed for parking expenses.
