Which finding would most strongly prompt a neurological evaluation when assessing a child with suspected motor-speech involvement?

• A. Fasciculations on protrusion
• B. High palate
• C. Normal posture
• D. Normal saliva

Answer: (A)

Fasciculations on tongue protrusion indicate motor-unit instability, typically from lower motor neuron or neuromuscular junction involvement. In a child where motor-speech issues are suspected, seeing spontaneous tongue twitches points toward a neuromuscular cause rather than a purely developmental speech delay. That’s why it would most strongly prompt a neurological evaluation: it suggests the muscles involved in speech and swallowing may be affected and require focused assessment, imaging or testing as needed to identify conditions that could impact bulbar function.

A high palate could affect resonance or articulation in some syndromes, but on its own it does not signal active neuromuscular disease. Normal posture and normal saliva suggest no gross motor weakness or bulbar dysfunction at rest, so they are less concerning in this context.
