The Michael J. Fox Foundation's staff Neurologist and Movement Disorder Specialist, Maurizio Facheris, MD, responds to questions on the causes of Parkinson's disease.

The "Ask the MD" series is intended as an educational resource for the Parkinson's community, their families, and friends. Please consult with your health care provider to address personal medical questions. We hope these videos provide you with a general source of knowledge and to feel more empowered when meeting with your doctor.
