Deep brain stimulation
In 1999, DBS was approved for Tourette syndrome - an inherited neurological disorder. Deep brain stimulation is used to treat patients with severe Tourette syndrome when medication does not help the patient. Many patients have fewer symptoms after DBS. In some patients, the DBS is only put on one side of the brain. This can reduce symptoms and patients may have fewer side effects when the stimulation is only put on one side of the brain.
