Adult tics in Gilles de la Tourette's syndrome: description and risk factors.
We studied 58 adults with Gilles de la Tourette's syndrome diagnosed during childhood. Tics persisted in all patients but were moderate/severe in only 24%, compared with 60% at the time of worst function. Coprolalia persisted in 4%, compared with 22% at the time of worst function. For most patients, worst function occurred in adolescence (mode = 13 years). In spite of a high frequency of school and behavioral problems during development, 98% graduated high school and 90% were full-time students or fully employed. Features predictive of mild tic severity in adulthood were mild tics during the patient's worst pre-adulthood function and mild tics during early and late adolescence. Childhood tic severity had no predictive value, and likewise, coprolalia during development did not increase the risk for adult moderate/severe tics.
