Dr. Michael S. Okun, national medical director of the National Parkinson Foundation, praised the study, saying it opens the door to "the hope for better symptomatic therapies in Parkinson's disease, though patients should clearly understand their limitations."
Okun added, "The gene therapy approach is clever and different. This is an important study, particularly in terms of safety. It will be important to follow these patients longer to look for delayed benefits and potentially delayed risks."
The U.S. National Institute of Neurological Disorders and Stroke has more on Parkinson's disease.
