Vancouver, BC—Deep brain stimulation and cell transplantation have fired interest in the surgical treatment of patients with Parkinson disease (PD), particularly those with more advanced, severe disease.
One factor pushing the resurgence of surgical treatment is the limited success of medical therapy with levodopa, said C. Warren Olanow, MD, chair of neurology at Mount Sinai School of Medicine in New York City, who spoke on "surgery from a physician's point of view" at the 13th International Congress on Parkinson Disease here in July.
