In order to diagnose TS, the child’s doctor will probably refer them to a neurologist. To be able to see a neurologist and begin treatment, the child must have had Tourettes for at least at year.  Even though tics occur nearly every day, for TS to be diagnosed, there must never be a tic-free period of time longer than three months. The neurologist may ask the child and their parents to keep track of the tic’s frequencies at home and at school.

If a case of TS gets so severe that the person is eating too much or too little, it is said that changing the diet could possibly eliminate the tics forever. If this does occur, the patient should consult with the doctor about what to do to the diet to hopefully say goodbye to tics forever.
