What Is Tourette Syndrome and What Causes It?

Q:
What is tourette syndrome and what causes it?

A:
Overview
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.

Causes
The exact cause of Tourette syndrome isn’t known.

It’s a complex disorder likely caused by a combination of inherited (genetic) and environmental factors.

Chemicals in the brain that transmit nerve impulses (neurotransmitters), including dopamine and serotonin, might play a role.
