Tourette's disorder is a brain condition that starts in childhood. Children with Tourette's make sounds or movements—such as coughing or twitching—that they can't control. These are called tics.
Tics usually start at about age 2. They may be at their worst by age 12. Tics tend to decrease during teenage years. They can continue into adulthood but occur less often and are less severe than in childhood.

Tourette's tends to run in families. Other things that may increase the risk include:

vomiting during the first trimester of pregnancy, was under severe stress
during her pregnancy, or who drank a lot of coffee, smoked cigarettes, or drank
alcohol during her pregnancy.
Not having enough oxygen or blood supply
A low birth weight and signs of brain injury or an

What are the symptoms?
Most children with Tourette's have different patterns of tics. The tics may not be obvious. They can be bursts of movement or sounds that last for seconds or minutes.
Tics can include:
A slight twitching of the eyes.
Jerking of the neck.
Coughing or throat-clearing.
A mix of movements and sounds.
It's common for a person who has Tourette's to feel an urge in some part of the body that builds and builds. This urge can only be relieved by performing the tic. But not everyone with the disorder is aware of these urges.
How is Tourette's disorder diagnosed?
A doctor can diagnose Tourette's based on your child's medical history and symptoms. The doctor may want to know if tics are causing school or social problems for your child.
Treatment for Tourette's disorder focuses on helping your child cope with the tics. Understanding how tics affect your child can help you and your child know what to expect. It may help to identify when tics occur and what is going on in your child's life during those times.
If tics are seriously affecting your child's quality of life at home or school, then counseling, behavioral therapy to reduce tics (habit reversal), and medicines may help. If your child has other medical problems, these may need to be treated first to see how they affect your child's symptoms.
