Dr DeMarcaida is extremely knowledgeable and works closely with the patient to resolve the issues. She considers alternative approaches for treatment and is very skilled at performing the treatments- always alert to possible pain or discomfort (which I don't have).

J. Antonelle de Marcaida, M.D. is the Medical Director of the Chase Family Movement Disorders Center of Hartford HealthCare and Associate Clinical Professor of Neurology. Under her leadership, the Chase Family Movement Disorders Center has grown from a single-center/single-doctor practice in Vernon, CT in November 2015, to the comprehensive fully integrated program that now exists in six locations all across the state and a team of ten of the most highly regarded Movement Disorders specialists in the region. She completed a two-year fellowship in Experimental Therapeutics and Movement Disorders at the University of Rochester under the mentorship of Drs. Ira Shoulson and Karl Kieburtz, and a one-year NIH funded fellowship in Experimental Therapeutics and Neuro-AIDS. She did her neurology residency at the University of Connecticut and her medicine internship at New York Medical College-Metropolitan Hospital. She has been the Principal Investigator for over forty clinical trials for Parkinson disease and other movement disorders, and has authored numerous publications and textbook chapters in the course of her career. She is also the Program Director of the Movement Disorders Fellowship Program of the University of Connecticut and Hartford HealthCare, encouraging a future generation of young physicians to develop the skills and passion for the field.

Dr. de Marcaida has a special interest in evaluating novel pharmacologic and non-pharmacologic interventions, including the role of naturopathic and Complementary and Alternative Medicine, in the management of PD and other movement disorders. She advocates strongly for a shift away from a single-minded focus on the management of disease, to a broader perspective on the importance of overall wellness and well-being as a better approach to care. She is passionate about caring for her patients from diagnosis to hospice, and being a true partner in their journey through a life that she aspires will be no less full despite their neurologic diagnosis. She is also fervently involved in various initiatives addressing health inequity and racial injustice, at work and in her community.
