Which comorbidities should be considered when diagnosing AOS?

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

Answer: (D)

When diagnosing AOS, assess for related motor speech and communication disorders because they commonly occur together and shape how the profile is understood and treated. Aphasia often accompanies left-hemisphere damage, so language impairment may be present alongside speech-planning difficulties. Dysarthria reflects problems with the execution of speech movements, which can co-occur with AOS and affect articulation and intelligibility. Apraxia of limb shows broader motor planning challenges in the limbs, indicating that the motor planning network involved in speech may be impacted as well. Because these comorbidities influence diagnosis and therapy planning, all of the above should be considered. Therefore, all of the above is the best choice.
