Synonyms
Historically, acquired apraxia of speech (AOS) has been known under a variety of terminological designations (e.g., aphemia, phonemic disintegration, cortical dysarthria, dyspraxia of speech). Currently, there are no acceptable synonyms in use. The descriptor, “stroke induced” (SI), has occasionally been used to specify AOS resulting from stroke (e.g., SI-AOS). Primary progressive apraxia of speech (PPAOS) is used to designate AOS associated with neurodegenerative disease.
Definition
AOS is a neurologic, motoric disorder of speech production that is characterized by slowed rate of speech, difficulties in sound production, and disrupted prosody. AOS is not a disorder of language, although it rarely occurs without aphasia. Consequently, there is no impairment of comprehension or production of language in pure AOS.
Categorization
AOS currently does not have subcategories but is differentiated relative to onset and progression: PPAOS (primary progressive) or AOS/SI-AOS (sudden...
