Tourette syndrome is a neurological disorder where repetitive movements or unwanted sounds, called tics, can't be controlled by a person. According to the Mayo Clinic, there is no cure for Tourette syndrome.
Signs and symptoms of Tourette syndrome may start to show up in children between the ages of 2 and 12. The Mayo Clinic states that the average age when a child begins to show signs of Tourette's is seven. People who have Tourette syndrome display two different types of tics: motor tics and verbal tics. A simple motor tic can be repetitive eye blinking, and a complex motor tic can be flapping of the arms. A simple verbal tic can include yelling when trying to verbalize, and a complex verbal tic can be repeating the same word or phrase.
