What is Deep Brain Stimulation for Parkinson’s Disease?<\/strong><\/h2>\n

\"\"Deep brain stimulation (DBS) is a surgical procedure used to treat a variety of disabling neurological symptoms\u2014most commonly the debilitating symptoms of Parkinson\u2019s disease (PD), such as tremor, rigidity, stiffness, slowed movement, and walking problems.\u00a0The procedure is also used to treat essential tremor, a common neurological movement disorder.\u00a0At present, the procedure is used only for patients whose symptoms cannot be adequately controlled with medications.<\/p>\n

DBS uses a surgically implanted, battery-operated medical device called a neurostimulator\u2014similar to a heart pacemaker and approximately the size of a stopwatch\u2014to deliver electrical stimulation to targeted areas in the brain that control movement, blocking the abnormal nerve signals that cause tremor and PD symptoms.
\nBefore the procedure, a neurosurgeon uses magnetic resonance imaging (MRI) or computed tomography (CT) scanning to identify and locate the exact target within the brain where electrical nerve signals generate the PD symptoms.<\/p>\n

\"\"Some surgeons may use microelectrode recording\u2014which involves a small wire that monitors the activity of nerve cells in the target area\u2014to more specifically identify the precise brain target that will be stimulated.\u00a0Generally, these targets are the thalamus, subthalamic nucleus, and globus pallidus.The DBS system consists of three components:\u00a0the lead, the extension, and the neurostimulator.<\/p>\n

The lead (also called an electrode)\u2014a thin, insulated wire\u2014is inserted through a small opening in the skull and implanted in the brain.\u00a0The tip of the electrode is positioned within the targeted brain area.<\/p>\n

\"\"<\/p>\n

The extension is an insulated wire that is passed under the skin of the head, neck, and shoulder, connectng the lead to the neurostimulator.<\/p>\n

\"\"The neurostimulator (the “battery pack”) is the third component and is usually implanted under the skin near the collarbone.\u00a0In some cases it may be implanted lower in the chest or under the skin over the abdomen.
\nOnce the system is in place, electrical impulses are sent from the neurostimulator up along the extension wire and the lead and into the brain.\u00a0These impulses interfere with and block the electrical signals that cause PD symptoms.<\/p>\n

\"\"Unlike previous surgeries for PD, DBS does not damage healthy brain tissue by destroying nerve cells.\u00a0Instead the procedure blocks electrical signals from targeted areas in the brain.\u00a0Thus, if newer, more promising treatments develop in the future, the DBS procedure can be reversed.\u00a0Also, stimulation from the neurostimulator is easily adjustable\u2014without further surgery\u2014if the patient\u2019s condition changes.\u00a0Some people describe the stimulator adjustments as “programming.”<\/p>\n

 <\/p>\n

What is the prognosis?<\/h3>\n

Although most patients still need to take medication after undergoing DBS, many patients experience considerable reduction of their PD symptoms and are able to greatly reduce their medications.\u00a0The amount of reduction varies from patient to patient but can be considerably reduced in most patients.\u00a0The reduction in dose of medication leads to a significant improvement in side effects such as dyskinesias (involuntary movements caused by long-term use of levodopa).\u00a0In some cases, the stimulation itself can suppress dyskinesias without a reduction in medication.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
