Deep brain stimulation (DBS) uses electrical impulses to stimulate a target area in the brain. The stimulation affects movement by altering the activity in that area of the brain. The procedure does not destroy any brain tissue. And stimulation can be changed or stopped at any time.
DBS can improve your quality of life when medication for movement disorders alone has reached its limits. It isn't a cure, but can relieve symptoms of Parkinson's disease, essential tremor, or dystonia.
