Dysarthria arises from impairment in which domain?

• A. Attention
• B. Visual processing
• C. Language comprehension
• D. Motor control of speech muscles

Answer: (D)

Dysarthria is a motor speech disorder, so the key idea is impaired control of the muscles used to articulate speech. The problem lies in the execution and coordination of the lips, tongue, velum, larynx, and breathing muscles, which leads to slurred, slowed, or imprecise speech. This is different from attention problems, visual processing issues, or difficulties with understanding language, which affect other aspects of communication but not the actual muscular execution of speech. In short, dysarthria reflects impaired motor control of the speech muscles.
