When an appropriately experienced physician finds typical indications of Tourette syndrome (TS) in the patient's history and examination, no further workup is generally necessary. Further workup may be needed if unusual features are present in the history or physical examination or if other abnormalities are found on neurological examination.

Unusual findings may include rigidity, bradykinesia, spasticity, myoclonus, chorea, dementia, or psychosis. Further workup may include corroboration of the patient's history with that of another source, with clinical follow-up, or with laboratory testing.
