Tourette’s Disorder

What is Tourette’s Disorder?

Tics are sudden, rapid, and recurrent motor movements or vocalizations. Tourette’s Disorder is a tic disorder characterized by the presence of both motor and vocal tics. Persistent (Chronic) Motor or Vocal Tic Disorder is characterized by the presence of either motor or vocal tics, but not both. In contrast to tics in Tourette’s Disorder and Persistent (Chronic) Motor or Vocal Tic Disorder, the tics in Provisional Tic Disorder have been present for less than a year.
