Deep brain stimulation may be able to reduce the symptoms of Parkinson's Disease.
A new study published in the Journal Neurology looked at more than 150 people with Parkinson's Disease. Each participant underwent deep brain stimulation to one of two areas of the brain thought to be involved in the disease.
All the participants saw their symptoms improve 30 percent during the three-year study. Stimulating one area of the brain appeared to slow the decline of thinking skills more than the other, but the researchers say more studies are needed.
They say this study adds to the mounting evidence that deep brain stimulation can alleviate some of the symptoms of the disease.
About 50% of the participants were not followed for the full three-year study because of study design flaws.
The study was partially funded by Medtronic Neurological, Inc.
