Which symptom indicates impairment of both motor function and speech in Huntington's disease?

Explanation:
Huntington's disease disrupts coordinated motor control, affecting muscles used for both speech and swallowing. When a symptom shows difficulty with both swallowing and speaking, it indicates impairment in two motor domains—feeding and communication—rather than a single area. Dysphagia and dysarthria commonly occur together as the disease progresses, whereas memory loss points more to cognitive decline. Therefore, the combination of swallowing and speech difficulties best signals impairment of both motor function and speech.
