What is deep brain stimulation for Parkinson’s?
Deep brain stimulation (DBS) delivers electrical impulses to a targeted area of the brain that is responsible for the movement symptoms (also called motor symptoms) caused by Parkinson’s disease. The electrical impulses disrupt the abnormal activity that occurs in the brain’s circuitry, which is causing the symptoms.

During this visit, your neurologist will evaluate you and program the deep brain stimulator. We monitor your movements to help determine the correct settings and intensity for the stimulator.
What are the causes of dystonia?
Dystonia may be an inherited condition caused by genetic mutations. It can also result from exposure to certain drugs, birth injuries, strokes, or as a symptom of other neurological disorders.
