Which of the following is NOT a dysarthria type?

• A. Flaccid
• B. Spastic
• C. Hypernasal
• D. Ataxic

Answer: (C)

Hypernasal speech is not a dysarthria type. The main idea is that dysarthria types describe motor speech disorders defined by patterns of neurological involvement affecting the muscles used for speech. Classic types include flaccid dysarthria from lower motor neuron weakness, spastic dysarthria from bilateral upper motor neuron damage with increased tone, and ataxic dysarthria from cerebellar dysfunction causing coordination problems. Hypernasality is a resonance abnormality—air escaping through the nose due to insufficient velopharyngeal closure—that can appear with several dysarthrias or other conditions but is not itself a distinct motor speech disorder category.
