Biography
Dr. Sarah O’Shea is an Assistant Professor of Neurology at Chobanian and Avedisian School of Medicine and practices at Boston Medical Center, where she cares for patients with Parkinson’s disease, atypical parkinsonism, Huntington’s disease, and tremor. She also specializes in Deep Brain Stimulation (DBS) for Movement Disorders and is also skilled in botulinum toxin injections for Movement Disorders and spasticity. Her research interests include investigating prodromal markers of Parkinson’s disease and the effects of neurotoxicant exposure on the development of neurodegenerative disease. She also has a research interest in DBS outcomes, particularly neuropsychological outcomes after DBS surgery.
Dr. O’Shea received her BA in Biological Sciences at Northwestern University and her MD at the University of Illinois. She completed her neurology residency at the University of Iowa, where she served as Chief Resident. She completed a three-year fellowship in Movement Disorders at Columbia University/New York-Presbyterian Hospital. She also obtained an MS in Epidemiology at Columbia University during her fellowship training (Neuroepidemiology Training Program).
