Gilles de la Tourette Syndrome
Alternate Names : Tourette Syndrome
Diagnosis & Tests
There are no specific lab tests to confirm a diagnosis of Tourette syndrome. However, a thorough examination by a qualified physician should be performed to rule out other causes of these symptoms.
Diagnostic Criteria:
- Both multiple motor and one or more vocal tics have been present at some time during the illness, although not necessarily at the same time.
- Tics occur many times a day, nearly every day or intermittently, throughout a period of more than 1 year. During this period there must not be a tic-free period of more than 3 consecutive months.
- Onset is before 18 years of age.
