Deep brain stimulation (DBS) uses a medical device to stimulate the source of the symptoms of essential tremor on one side of the body. Clinical studies have shown that DBS Therapy for essential tremor provides enhanced ability to do everyday activities, less tremor, and less disability (as reported by the patients).1
DBS is indicated to treat one “upper extremity,” which means one arm and hand. DBS may help symptoms of essential tremor that happen with or without trying to move.
When medications aren’t effective and the symptoms make everyday life a challenge, DBS may help. Symptom control may help to continue doing what’s important, like taking care of family or continuing to work.
DBS Therapy is not for everyone, so it's important to talk with the doctor about the benefits and risks.
DBS Therapy uses a small, pacemaker-like device, placed under the skin of the chest, to send electrical signals through a very thin wire (lead) to an area in the brain that controls movement. These signals block some of the brain messages that cause the movement symptoms of essential tremor.
