FDA approves DBS
The Federal Food and Drug Administration approves deep brain stimulation (DBS) for Parkinson’s disease (PD). According to NIH National Institute of Neurological Disorders and Stroke:
DBS is a surgical procedure used to treat disabling motor symptoms of PD, such as tremor, rigidity, stiffness, slowed movement and walking problems. The DBS system consists of the lead, the extension, and the IPG. The lead—a thin, insulated wire also called an electrode—is inserted through a small opening in the skull and implanted in the brain. The tip of the electrode is positioned within a specific brain area. The implantable pulse generator (IPG)—similar to a heart pacemaker—delivers electrical stimulation to specific areas in the brain that control movement. Once the system is in place, electrical impulses are sent from the IPG up along the extension wire and the lead and into the brain. These impulses block abnormal electrical signals and alleviate PD motor symptoms.
