Tourette syndrome is a condition that affects a person's central nervous system and causes tics (movements or sounds that a person can't control and that are repeated over and over).
Throat clearing, grunting, and coughing are all common vocal tics. Tics are usually worse when a person is under stress (like when studying for a big test) or excited or very energized about something (like at a birthday party or a sports activity).
A person with Tourette syndrome sometimes has more than one type of tic happening at once. But tics often happen less or go away completely when a person is concentrating (like working on a computer) or relaxing (like listening to music). Tics can even happen when a person first falls asleep, but usually slow down and disappear completely during the deeper stages of sleep.
All kids who have Tourette syndrome have tics — but a person can have tics without having Tourette syndrome.
Some health conditions and medicine, for instance, can cause tics.
Sometimes a person with Tourette syndrome might have other conditions, like attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), or trouble learning.
Tourette syndrome is a genetic condition, which means it's passed down from a person's parents.There's no cure for Tourette syndrome, but most of the time no treatment is needed.A kid with Tourette syndrome is able to deal with the tics and still do normal stuff, like go to school and play with friends.And many kids have tics that disappear on their own in a few months or a year.So, it's important for doctors to know what's causing the tics.Tourette syndrome is not contagious and you can't catch it from someone who has it.
