Deep brain stimulation

Deep brain stimulation involves implanting electrodes within certain areas of your brain. These electrodes produce electrical impulses that regulate abnormal impulses. Or, the electrical impulses can affect certain cells and chemicals within the brain. The amount of stimulation in deep brain stimulation is controlled by a pacemaker-like device placed under the skin in your upper chest. A wire that travels under your skin connects this device to the electrodes in your brain.

Deep brain stimulation is used to treat a number of neurological conditions, such as:

  • Essential tremor
  • Parkinson's disease
  • Dystonia

Deep brain stimulation is also being studied as a treatment for epilepsy, cluster headaches, Tourette syndrome, chronic pain and major depression. Many candidates for deep brain stimulation are participants in clinical trials.

Why it's done Risks How you prepare What you can expect Results

Deep brain stimulation is an established treatment for movement disorders, such as essential tremor, Parkinson's disease, and dystonia, and more recently, obsessive-compulsive disorder. This treatment is usually reserved for people who aren't able to get control of their symptoms with medications.
