Question

which is a symptom that is common in people with huntingtons disease?
pain
nausea
delayed growth
involuntary movement

Explanation:

Huntington's disease is a neurodegenerative disorder. One of its hallmark symptoms is chorea, which are involuntary, jerky movements. Pain is not a typical main symptom of Huntington's. Nausea is also not a common, defining symptom. Delayed growth is not associated with Huntington's as it primarily affects the nervous system in adults (onset usually middle - aged) and not growth processes.

Answer:

involuntary movement
