Synopsis

Tourette syndrome is a neurologic disorder characterized by repeated involuntary movements (motor tics) and uncontrollable vocal sounds (vocal tics). Symptoms are usually manifested before age 18. They occur in the setting of a normal mental status and clear sensorium. They are partially voluntarily controlled in that they may be temporarily suppressible, but afterward, on release, they are more pronounced. The severity and extent of the tics can fluctuate greatly over months and years, with periods of relative quiescence. Inquiry should be made regarding childhood habits, including persistent throat clearing, humming, or twitches.

For more information, see OMIM.
