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 the hallmark symptoms is chorea, which are involuntary, jerky movements. Pain is not a typical main - stay symptom of Huntington's. Nausea is more associated with gastrointestinal disorders or other systemic issues rather than being a common symptom of Huntington's. Delayed growth is not a characteristic symptom of this disease as it primarily affects the nervous system in adults (onset is usually in middle - age) and not the growth - related hormonal or skeletal systems.

Answer:

involuntary movement
