Children at Risk
Tourette's Disorder occurs in approximately four to five individuals per 10,000. It can occur in people with a wide range of racial and ethnic backgrounds.
Children with TD are usually of normal intelligence and most do not have primary learning disabilities.
The age of onset of TD may be as early as 2 years of age, but usually occurs during childhood or early adolescence and by definition before 18 years of age. The duration is usually lifelong, though periods of remission from weeks to several years may occur. In most cases, the severity, frequency and variability of the symptoms diminish during adolescence and adulthood. In other cases the symptoms disappear entirely, usually by early adulthood.
Tourette’s is about one to three times more common in males than in females.
