Darley's contributions to the understanding and diagnosis of developmental apraxia of speech

In addition to his well-acknowledged work in the area of acquired neurologic communication disorders, Fred Darley also made significant contributions to how we think about speech disorders in children. His careful attention to nosology and his expertise in differential diagnosis led to a specific and important contribution in the area of developmental apraxia of speech. His work, along with Dr. Yoss, contributed significantly to our understanding of this developmental motor speech disorder, as well as to the development of assessment and treatment strategies for this group of children. This paper will examine Darley's work in developmental apraxia of speech, both as a clinician and as a researcher.
