Brain Stimulation Effective for Parkinson's

WEDNESDAY, Aug. 30 (HealthDay News) -- Deep brain stimulation -- a surgical procedure to reduce Parkinson's symptoms -- is more effective for patients with advanced disease than medication and may have fewer side effects than drugs do.

Those are the conclusions of a new study that found nearly a 25 percent improvement in symptoms in those undergoing deep brain stimulation while the medication group stayed the same.

"Deep brain stimulation improves the quality of life in patients with advanced Parkinson's disease at a stage when medical treatment is no longer able to improve quality of life," said the study's lead author, Dr. Guenther Deuschl, professor of neurology and chairman of the department of neurology at Christian-Albrechts University in Kiel, Germany.
