Earliest Signs of Parkinson's Disease with D. James Surmeier, PhD

Northwestern Medicine scientists have discovered one of the earliest signs of Parkinson's disease, proving that damaged neuronal mitochondria alone can cause symptoms of the disease, according to a study published in Nature. Senior author D. James Surmeier, chair of the Feinberg department of Neuroscience, who has over 30 years of experience in the field, explains the importance of these findings for future Parkinson's research and therapeutics.
