Darley's contributions to the understanding, differential diagnosis, and scientific study of the dysarthrias

Abstract

The work of Frederic L. Darley and his colleagues has done much to shape approaches to the clinical diagnosis and understanding of the dysarthrias and the scientific study of speech production. From the perspective of the speech pathologist and the perspective of the speech scientist, this paper examines Darley's contributions to the clinical diagnosis and management of the dysarthrias, to the localisation and diagnosis of neurologic disease, to descriptions of the perceptual representations of disordered speech, and to efforts to integrate information about disordered neural control of speech with information about the normal neural control of speech. Gaps in knowledge and directions for future work in each of these areas are also discussed.
