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.
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.
