Provisional Tic Disorder

Single or multiple motor and/or vocal tics.

The tics have been present for less than 1 year since first tic onset.

Onset is before age 18 years.

The disturbance is not attributable to the physiological effects of a substance (e.g., cocaine) or another medical condition (e.g., Huntington’s disease, postviral encephalitis).

Criteria have never been met for Tourette’s disorder or persistent (chronic) motor or vocal tic disorder.
