A person staggers while walking but thinking and memory are normal. Which part is more likely affected?
Answer and explanation
Correct answer: Cerebellum
The governing concept is division of labour among brain regions. The cerebellum coordinates voluntary muscular movements, posture, and balance, so its disturbance can cause staggering while walking. Normal thinking and memory make major forebrain involvement less likely in this case. The thyroid and pancreas are endocrine organs and do not primarily coordinate immediate balance and locomotion. Hence option A is the best answer.
