Tourette's syndrome is an inherited psychiatric disorder attributed to the nervous system with symptoms arising in childhood causing multiple motor tics and at least one verbal tic, not always occurring together. These repetitive, sudden, involuntary movements and exclamations come and go, with changes in intensity. When severe, muscle impulses can result in self-harm and in a small portion of people, coprolalia (inappropriate or derogatory utterances) or echolalia (repetition of words spoken by others) is present. Symptoms usually become less intense during adolescence.
The exact cause of Tourette’s remains unclear, but it is thought that factors such as genetics and one’s environment contribute to its development. There are some medications and therapies that may help to control the tics, but there is no one medication for treatment of all cases. Most patients do not require medication.
