Deep Brain Stimulation for Parkinsons Disease This publication provides an overview of deep brain stimulation (DBS), a surgical procedure used to treat several disabling neurological symptoms—most commonly the debilitating motor symptoms of Parkinsons disease, such as tremor, rigidity, stiffness, slowed movement, and walking problems. The procedure is also used to treat essential tremor and dystonia. The publications describes the DBS system and its advantages for patients. Also discussed is NINDS-funded research on DBS, including studies to further improve the system. A list of sources of additional information about Parkinson's disease is included as well.
