Deep brain stimulation (DBS), a surgical therapy for Parkinson's disease, is typically considered when a person who has had Parkinson's for four years or more develops complications, such as dyskinesia (uncontrolled, involuntary movements) and/or significant "off" time (when medication isn't working optimally and symptoms return). Like all currently available Parkinson's therapies, DBS is a symptomatic treatment -- it eases motor symptoms but does not change the underlying course of disease. DBS doesn't work for all symptoms, including balance problems or freezing while walking, and can even worsen some non-motor symptoms, such as memory problems. It isn't for everyone but in the appropriate person, it can lessen symptoms, medication requirements and the side effects that can accompany medications.
