Tourette's Syndrome

Tourette's syndrome is an inherited condition that causes a certain part of your brain to function incorrectly. It causes an excessive activity of dopamine, a brain chemical that normally controls our body's movements. Some cases of Tourette's syndrome may be caused by an immune reaction to a streptococcal infection, or by other unknown environmental factors.

Tourette's syndrome patients have involuntary jerks and twitches of the face, head, shoulders and other areas of the body and also make involuntary sounds, such as sniffing, grunting, squealing or swearing. The symptoms change in frequency and may move from one part of the body to another. This disorder usually starts at age five to seven, though it can begin anytime before age 18.
