Which deficits characterize speech and communication problems after a stroke?

• A. Aphasia
• B. Speech fluency problems only
• C. Voice quality changes
• D. Dyspraxia and dysarthria

Answer: (D)

When a stroke affects the brain areas that control both the planning and the execution of speech, the most typical deficits show up in how speech is produced. Dysarthria arises from weakness, spasticity, or discoordination of the muscles used for speaking, so speech can be slurred, slow, imperfectly articulated, and accompanied by altered voice quality. Dyspraxia of speech, or apraxia of speech, occurs when the brain has trouble planning and sequencing the exact movements needed to say words; the person knows what they want to say but struggles to coordinate the movements, often with inconsistent errors. Together, these motor speech problems directly impact how clearly and smoothly a person can communicate after a stroke. Aphasia describes difficulties with language processing—understanding or formulating words and sentences—not the motor execution of speech, so while communication can be impaired, it’s a different type of deficit. Voice quality changes can occur but are usually part of the broader motor-speech picture (dysarthria) rather than the defining issue on its own. Fluency issues alone don’t capture the full range of motor planning and execution problems that characteristically affect speech after a stroke, which is why the combination of dyspraxia and dysarthria best characterizes post-stroke speech and communication deficits.
