Tics are the main symptom of Tourette's syndrome. They usually appear in childhood between the ages of 2 and 14 (around 6 years is the average).
People with Tourette's syndrome have a combination of physical and vocal tics.
Examples of physical tics include:
- blinking
- eye rolling
- grimacing
- shoulder shrugging
- jerking of the head or limbs
- jumping
- twirling
- touching objects and other people
Examples of vocal tics include:
- grunting
- throat clearing
- whistling
- coughing
- tongue clicking
- animal sounds
- saying random words and phrases
- repeating a sound, word or phrase
- swearing
Swearing is rare and only affects about 1 in 10 people with Tourette's syndrome.
