Deep Brain Stimulation for Parkinson's
Although most people still need to take Parkinson's disease medication after undergoing deep brain stimulation, many experience a considerable improvement in their symptoms and are able to greatly reduce the amount of medication they take. While this varies from person to person, most can reduce their medications significantly. Reducing the dose of medication usually leads to a significant improvement in side effects such as dyskinesias (involuntary movements caused by long-term use of levodopa). In some cases, the deep brain stimulation itself can suppress dyskinesias without a reduction in medication.
