Deep Brain Stimulation Therapy in Movement Disorders

Background: \- In deep brain stimulation (DBS), a device called a neurostimulator is placed in the chest. It is attached to wires in parts of the brain that affect movement. DBS might help people with movement disorders like Parkinson s disease (PD), dystonia, and essential tremor (ET). Objective: \- To provide DBS treatment to people with some movement disorders. Eligibility: \- Adults 18 years and older with PD, ET, or certain forms of dystonia. Design: * Participants will be screened with medical history and physical exam. They will have blood and urine tests and: * MRI brain scan. The participant will lie on a table that slides in and out of a metal cylinder with a magnetic field. They will be in the scanner about 60 minutes. They will get earplugs for the loud noises. During part of the MRI, a needle will guide a thin plastic tube into an arm vein and a dye will be injected. * Electrocardiogram. Metal disks or sticky pads will be placed on the chest, arms, and legs. They record heart activity. * Chest X-ray. * Tests of memory, attention, concentration, thinking, and movement. * Eligible participants will have DBS surgery. The surgery and hospital care afterward are NOT part of this protocol. * Study doctors will see participants 3 4 weeks after surgery to turn on the neurostimulator. * Participants will return every month for 3 months, then every 3 months during the first year, and every 6 months during the second year. Each time, participants will be examined and answer questions. DBS placement will be evaluated with MRI. The neurostimulator will be programmed. At two visits, participants will have tests of movements, thinking, and memory.
