Deep brain stimulation (DBS) uses one or two surgically implanted medical devices called neurostimulators, similar to cardiac pacemakers, to deliver electrical stimulation to precisely targeted areas on each side of the brain. Stimulation of these areas appears to block the signals that cause the disabling motor symptoms of Parkinson’s. As a result, many patients achieve greater control over their body movements. DBS is used mainly to treat people with advanced Parkinson’s disease, but also other movement disorders such as essential tremor and dystonia.
