Which comorbidity checklist is appropriate when diagnosing AOS?

• A. Aphasia
• B. Dysarthria
• C. Apraxia of limb
• D. All of the above

Answer: (D)

When evaluating AOS, you look broadly at related motor and language functions because these issues often occur together. Aphasia is frequently present with AOS due to shared left-hemisphere damage affecting language networks. Dysarthria can accompany AOS as a separate motor speech impairment affecting execution of speech movements. Apraxia of limb may also appear, reflecting broader praxis deficits that can co-occur with apraxia of speech. Using a comorbidity checklist that includes aphasia, dysarthria, and limb apraxia helps ensure you don’t miss overlapping conditions that influence diagnosis and treatment planning. All of the above is the best choice because it captures this comprehensive approach.
