Chronic Motor or Vocal Tic Disorder is defined by which of the following?

• A. Only motor tics
• B. Single or multiple motor or vocal tics, but not both, occurring many times a day, nearly every day for over a year, with onset before age 18
• C. Tics that occur but resolve within six months
• D. Onset after age 18

Answer: (B)

Chronic motor or vocal tic disorder is defined by tics that are either motor or vocal (not both) and persist for a long period. Specifically, the disorder involves one or more motor tics or one or more vocal tics that occur many times a day, nearly every day, for more than a year, with onset before age 18. This distinguishes it from conditions like Tourette’s, where both motor and vocal tics are present; from transient tic disorders, where tics resolve within a year; and from cases that begin after age 18. The key pieces are: a single type of tic (motor or vocal) that lasts over a year and begins before 18.
