Deep brain stimulation (DBS) is a procedure used to treat certain symptoms of Parkinson's disease.

It is designed to help patients with their tremor, and slowed movements, among other symptoms.

DBS uses electrical currents to "jam" abnormal brain signals.

DBS involves the implantation of a battery-operated pacemaker-like device (implanted pulse generator) under the collarbone. Attached to this device is a wire, which runs under the skin along the length of the neck up to the scalp.

The wire connects to an electrode, which is inserted into the target area deep inside the brain through a small hole in the skull.

Once in place, electrical impulses are sent from the implanted pulse generator to the tip of the electrode, these impulses interfere with the abnormal electrical signals that cause tremor and other symptoms of Parkinson's disease.

A number of symptoms typically respond very favorably to DBS, while other symptoms (e.g., problems with balance) do not tend to get much better.

Aside from Parkinson's disease, DBS surgery may also be performed for patients with Essential tremor (ET), refractory to standard medical treatment, and for patients with severe dystonia. The brain areas targeted for those diseases are different from the area targeted for Parkinson's disease.

How is the Neurotransmitter Implanted? Will I Need to be Hospitalized?

The DBS system is usually implanted in two stages. In the first stage, the electrode is guided through the small hole in the skull to the target location in the brain, which has been pre-selected by MRI. This process is done in part while the patient is awake for test stimulation of the electrode, to confirm proper placement during the surgery.

After this electrode placement, patients stay in the hospital for observation, typically for one night. About 2 weeks later, patients return for placement of the battery-operated pulse generator in the chest area. During this 2nd procedure, the wire from the electrode and the wire from the pulse generator are connected with each other. This procedure is typically a one-day stay, similar to the placement of a cardiac pacemaker.
