Abstract
Answer E. Tourette syndrome
Tourette syndrome involves motor and vocal tics. The typical age of onset is 6–7 years old. Tourette syndrome has strong genetic association with obsessive compulsive disorder. With this association, there is often a family tendency for male relatives to have tic disorders and for female relatives to be affected by obsessive compulsive disorder. Diagnostic criteria for Tourette syndrome include:
Multiple motor and one or more vocal tics at some point in illness May wax and wane but have persisted over 1 year Onset before the age of 18 Not caused by substance or other condition
