Tourette syndrome is a neurological disorder characterized by chronic tics.
Tics are involuntary movements in the body.
The tics can happen in the eyes, neck, arms, legs and other areas of the body. Doctors say tics are a devastating part of the disease for patients, because it's difficult for a patient to feel comfortable in social situations when they cannot control their movements. Patients with Tourette syndrome also experience discomfort and other sensations that precede the tic. Often doctors prescribe medications to control the tics, but these medications can have serious side effects. The injections have also been found to improve not only the tics, but also the sensations patients experience before the tics.
