Deep brain stimulation (DBS) therapy is a surgical treatment that can reduce some of the symptoms associated with Parkinson’s disease. This therapy uses a surgically implanted device, similar to a cardiac pacemaker that electrically stimulates the brain by blocking the signals that cause the disabling motor symptoms. Electrical stimulation can be adjusted noninvasively to maximize the benefits of therapy. As a result, many individuals have greater control over their body movements. A DBS system consists of three implanted components: an electrode implanted in the brain, which has four isolated thin wires arranged in a spiral with four poles on the electrode tip; an extension that is connected to the electrode and runs under the skin from the head to the upper chest through the neck; and a neurostimulator that connects to the extension. The implantation is typically performed under the skin in the chest.
