ESLA webinar series - "Childhood Apraxia of Speech (CAS): Differential Diagnosis"

Dr. Edythe Strand, PhD, CCC-SLP will give an interesting talk on “Childhood Apraxia of Speech (CAS): Differential Diagnosis”. 


Differential diagnosis of CAS has historically been difficult and controversial due to lack of a biomarker. There is now good consensus regarding the characteristics associated with this speech diagnosis label. In this webinar, both the non-discriminative and discriminative characteristics are described and differentiated. Assessment tasks helpful to the observation and interpretation of these characteristics are reviewed. Emphasis is given to the use of dynamic assessment to aid in differential diagnosis as well as judgments of severity and prognosis.


Dr. Edythe Strand is Emeritus Speech Pathologist, Professor at Mayo College of Medicine and Affiliate Professor at University of Washington. Dr. Strand’s research has focused on developmental, acquired and progressive apraxia of speech, as well as degenerative dysarthria. Honours include: Honours of the American Speech, Language and Hearing Association, Honours of the Academy of Neurologic Communication Disorders & Sciences, and the ASHFoundation, Frank R. Kleffner Lifetime Clinical Career Award.


In this webinar, participants will learn about the discriminative characteristics of CAS, allowing them to be able to describe a variety of assessment tasks leading to differentiating CAS from other speech sound disorders. Finally, participants will be able to explain how to do dynamic assessment and the advantages of using it for diagnosis.
