Tourette (too-RET) syndrome is a nervous system (neurological) disorder that starts in childhood. It involves unusual repetitive movements or unwanted sounds that can't be controlled (tics). For instance, you may repeatedly blink your eyes, shrug your shoulders or jerk your head. In some cases, you might unintentionally blurt out offensive words.
Signs and symptoms of Tourette syndrome typically show up between ages 2 and 12, with the average being around 7 years of age. Males are about three to four times more likely than females to develop Tourette syndrome.
Although there's no cure, you can live a normal life span with Tourette syndrome, and many people with Tourette syndrome don't need treatment when symptoms aren't troublesome. Symptoms of Tourette syndrome often lessen or become quiet and controlled after the teen years.
