What causes Tourette's syndrome?

ANSWER

Tourette's has been linked to different parts of the brain, including an area called the basal ganglia, which helps control body movements. Differences there may affect nerve cells and the chemicals that carry messages between them. Researchers think the trouble in this brain network may play a role in Tourette's.

Doctors don't know exactly what causes these problems in the brain, but genes probably play a role. It's likely that there is more than one cause.

People who have family members with Tourette's are more likely to get it themselves, but people in the same family may have different symptoms.
