Tourette syndrome (TS) is a chronic disorder of the nervous system known by its motor and vocal tics. These tics are rapid, involuntary movements or sounds that occur repeatedly.
Many people with TS also have one or more of the following problems:
- Compulsions and ritualistic behaviors
- (ADD or ADHD)
- Learning disabilities
- Difficulties with impulse control
- Sleep disorders
The exact cause of TS is unknown. However, brain chemicals, called dopamine and serotonin, are most likely involved.
There may be a genetic link to TS, although some have no known family history.
Risk Factors for TS
Males are three to four times more likely to be affected. Other factors that may increase your risk of TS include:
- Family history of TS
- Having other tic disorders
- Obsessive-compulsive disorder
TS Symptoms: Tics
To be TS, the tics must:
- Be present for more than one year
- Start before age 18
- Be both motor and vocal tics

- Complex — saying words or phrases that do not make sense in a given situation, saying obscene or socially unacceptable words
Tics range from mild to severe. They can occur suddenly and vary in the amount of time that they last. Tics may temporarily decrease with concentration or distraction. They may occur more often during tense and stressful situations.
While tics may occur throughout life, symptoms may improve throughout late adolescence or adulthood.
