“Tourette syndrome is a neurological (nervous system) tic disorder. It causes people to make sudden movements or sounds they can’t control. These are called tics. For example, someone with Tourette’s might blink or clear their throat over and over again. Some people may blurt out words they don’t intend to say (being just a noise or even a offensive word).

Some treatments may help control tics, but some people don’t need to take medications unless their symptoms bother them.

About 100,000 Americans have full-blown Tourette syndrome, but more people have a milder form of the disease. It often starts in childhood and affects more boys than girls. Symptoms often get better as children grow up. For some people, they go away completely.

Tourette syndrome is also sometimes called Tourette’s  or Tourette disorder.”
