Tourette (too-RET) syndrome is a disorder that involves repetitive movements or unwanted sounds (tics) that can't be easily controlled. For instance, you might repeatedly blink your eyes, shrug your shoulders or blurt out unusual sounds or offensive words. Tics typically show up between ages 2 and 15, with the average being around 6 years of age. Males are about three to four times more likely than females to develop Tourette syndrome. Although there's no cure for Tourette syndrome, treatments are available. Many people with Tourette syndrome don't need treatment when symptoms aren't troublesome. Tics often lessen or become controlled after the teen years. Before the onset of motor or vocal tics, you'll likely experience an uncomfortable bodily sensation (premonitory urge) such as an itch, a tingle, or tension. The expression of the tic brings relief. With great effort, some people with Tourette syndrome can temporarily stop or hold back a tic.
