The research interests of Joseph R. Duffy, Ph.D., include neurologic motor speech disorders (the dysarthrias and apraxia of speech), acquired language disorders (aphasia) and acquired psychogenic speech disturbances. The primary focus of his research has been on defining the distinguishing clinical characteristics of these neurologic disorders, establishing their neurologic correlates and refining their differential diagnosis. Dr. Duffy's research will contribute to more accurate clinical diagnosis of these conditions and the ability to predict their neurological localization and underlying disease process. This will have implications for early identification of certain acquired neurological diseases and their early medical treatment when effective treatments become available.
