Which statement accurately describes language and strength in AOS?

• A. Language and strength are relatively preserved.
• B. Language is severely impaired.
• C. Strength is markedly reduced.
• D. Language and strength are preserved.

Answer: (A)

In apraxia of speech, the challenge is planning and sequencing the movements needed for articulate speech, not understanding language or producing it in usual content. Because of that, language abilities like comprehension, vocabulary, and grammar are typically intact, and the strength of the speech muscles is preserved. Patients may have difficulty coordinating the timing and order of lips, tongue, and jaw movements, especially on complex or longer utterances, but they don’t have true language deficits or muscle weakness. So saying that language and strength are relatively preserved best captures what AOS looks like. If language were severely impaired or there were marked muscle weakness, that would point to other conditions such as aphasia or dysarthria, not classic AOS.
