Diagnostic Criteria for Tourette's Syndrome¹

• Both multiple motor and one or more vocal tics have been present at some time during the illness, although not necessarily concurrently. (A tic is a sudden, rapid, recurrent, nonrhythmic, stereotyped motor movement or vocalization.)
• The tics occur many times a day (usually in bouts) nearly every day or intermittently throughout a period of more than 1 year, and during this period there was never a tic-free period of more than 3 consecutive months.
• The onset is before age 18 years.
• The disturbance is not due to the direct physiological effects of a substance (eg, stimulants) or a general medical condition (eg, Huntington's disease or postviral encephalitis).

Criteria for the diagnosis of Tourette's Syndrome are provided to help healthcare professionals characterize conditions frequently comorbid with ADHD. CONCERTA^® is indicated only for the treatment of attention deficit hyperactivity disorder. CONCERTA^® is contraindicated in patients with Tourette's Syndrome, tics, or family history of Tourette's Syndrome.
