Tic Disorder Basics
Tourette’s Disorder is the best-known tic disorder, but not the most common. To be diagnosed with Tourette’s a child must have multiple motor tics and at least one vocal tic for more than a year.
Chronic Motor or Vocal Tic Disorder
If a child has either motor tics or vocal tics (but not both kinds), they would be diagnosed with chronic motor or vocal tic disorder.
