Chronic Motor or Vocal Tic Disorder
The work group is recommending that this disorder be classified as a Neurodevelopmental Disorder or another similar grouping of disorders.
A. Single or multiple motor tics or vocal tics, but not both, have been present at some time during the illness. (A tic is a sudden, rapid, recurrent, nonrhythmic motor movement or vocalization.)
B. The tics may wax and wane in frequency but have persisted for more than 1 year since first tic onset.
C. The onset is before age 18 years.
D. The disturbance is not due to the direct physiological effects of a substance (e.g., cocaine) or a general medical condition (e.g., stroke, Huntington’s disease, postviral encephalitis)
E. Criteria have never been met for Tourette's disorder.
Specify if:
Motor tics only
Vocal tics only
Criterion A: The definition of a tic has been made consistent with the other tic disorders.
Criterion B: The changes to Criterion B for Chronic Motor or Vocal Tic Disorder are identical to those for Tourette’s Disorder.
Criterion D: The use of stimulant medication as an example of a substance induced movement disorder is not consistent with the evidence base and has been removed. Other examples have been added to assist with diagnosis.

Chronic Motor or Vocal Tic Disorder
A. Single or multiple motor or vocal tics (i.e., sudden, rapid, recurrent, nonrhythmic, stereotyped motor movements or vocalizations), but not both, have been present at some time during the illness.
B. The tics occur many times a day nearly every day or intermittently throughout a period of more than 1 year, and during this period there was never a tic-free period of more than 3 consecutive months.
C. The onset is before age 18 years.
D. The disturbance is not due to the direct physiological effects of a substance (e.g., stimulants) or a general medical condition (e.g., Huntington’s disease or postviral encephalitis).
E. Criteria have never been met for Tourette’s Disorder.
