DSM-5 Tourettes Diagnosis Guidelines

The DSM-5 criteria for Tourette's syndrome include multiple motor tics and one or more vocal tics, persisting for more than one year, with onset before age 18, and not due to substances or other medical conditions.

Conditions such as substance-induced tics, stereotypic movement disorder, chorea, dystonia, and OCD can mimic Tourette's symptoms.

Tourette disorder was first included in the DSM-III as a distinct disorder, published in 1980. It was defined by multiple motor or vocal tics.
