Which statement about AOS is accurate?

• A. It is primarily a disorder of articulation and prosody.
• B. It is primarily a memory disorder.
• C. It is a language comprehension deficit.
• D. It is a pure execution deficit with no planning component.

Answer: (A)

AOS is best understood as a motor speech disorder rooted in impaired planning and programming of the movements used to speak. This planning breakdown shows up in the way people articulate sounds and shape their prosody. The defining clinical picture is difficulties with sequencing and coordinating the articulatory gestures needed for fluent speech, often with groping and inconsistent errors. Because those observable problems are mainly about how sounds are formed and how rhythm and stress are applied, describing it as a disorder of articulation and prosody accurately reflects what goes wrong in the speech motor system. The other possibilities don’t fit as well because memory issues don’t explain the rapid, sequential motor errors seen in AOS, language comprehension is usually not the primary deficit (AOS can occur with relatively intact understanding), and saying it’s a pure execution problem without planning ignores the essential role of planning and sequencing that drives the errors in AOS.
