Nothing can be done to prevent Tourette syndrome.
The effects of Tourette syndrome may vary over the course of the lives of affected persons. At times, the effects may almost disappear. Then, they return as pronounced as ever. Some affected persons are able to suppress the tics and sounds for very short periods of time.
Tourette syndrome is not contagious. It is an inherited disorder that can be passed from affected persons to their children. Genetic counseling is valuable for the relatives of affected persons.
