Answer

Diagnostic criteria for transient tic disorder (DSM-5 307.21) are as follows:

  • Single or multiple motor and/or vocal tics (eg, sudden, rapid, recurrent, nonrhythmic, stereotyped motor movement or vocalizations) are present

  • The tics occur many times a day, nearly every day for at least 4 weeks, but for no longer than 12 consecutive months

  • The onset is before age 18 years

  • The disturbance is not due to the direct physiologic effects of a substance (eg, stimulants) or a general medical condition (eg, Huntington disease or postviral encephalitis)

  • Criteria have never been met for TS or chronic motor or vocal tic disorder

  • Specify if this is a single or recurrent episode

Tic disorder not otherwise specified (DSM-5 307.20): This category is for disorders characterized by tics that do not meet criteria for a specific tic disorder. Examples include tics lasting less than 4 weeks or tics with an onset after age 18 years.
