1. Definitions, Description, Disease Course, and Associated Problems
Apraxia of speech (AOS) can occur as a prominent and sometimes primary or only manifestation of neurodegenerative disease. Join Dr. Joseph Duffy as he uses an illustrative case example to describe the clinical features of primary progressive apraxia of speech (PPAOS) from the time of onset to the patient’s death nearly ten years later. Dr. Duffy also discusses primary progressive aphasia (PPA), its variants, and the relationship of each PPA subtype to PPAOS.
2. Brief Case Examples
Through the presentation of four patient case examples, Dr. Duffy illustrates the history and presentation of PPAOS and progressive AOS accompanied by aphasia. Speech characteristics that justify the diagnosis of AOS are highlighted in the presented examples.
3. Neuroimaging Correlates and Underlying Pathology
Magnetic resonance imaging (MRI) and positron emission tomography (PET) scans of the brain reveal differences between PPAOS and PPA. Autopsy findings allow for further analysis of underlying pathology and histochemistry of PPAOS and PPA. In this course, Dr. Duffy highlights the importance of the clinical diagnostic distinction between these diagnoses relative to prediction of underlying pathology.
4. Management Issues
With limited data supporting treatment effectiveness for PAOS/PPOAS, clinicians largely rely on management and therapies for apraxia of speech and neurodegenerative communication disorders in general. Staging and counseling emerge as important components in the management of PPAOS.
5. Q&A
Dr. Duffy concludes this course by answering questions about apraxia of speech disorders from a speech and hearing sciences doctoral candidate.
