Colin T. McDonald, MD, specialized in neuro-critical care at Massachusetts General Hospital (Mass General), Harvard Medical School in Boston in 1998, when the father of an emergency room physician at an affiliated hospital became one of his patients. One morning, the father experienced symptoms of stroke, which the son immediately recognized. Doing something about those symptoms, however, was complicated; the father and son were on Martha's Vineyard, where the local hospital was not equipped for emergency neurology care.
