Title: Primary progressive apraxia of speech: What is it and what is it teaching us?
Abstract: This presentation will address a recently identified neurodegenerative clinical syndrome known as primary progressive apraxia of speech (PPAOS). The salient features of PPAOS will be reviewed, with illustrative cases, as will the research that has defined its demographics, associated neurologic deficits, evolution over time, and neuroimaging and histopathological correlates. Implications of these findings for our understanding of speech motor planning and programming, and its breakdown, will be discussed.
