Alzheimer's disease is associated with early involvement of which brain structure that processes memory?

• A. Hippocampus
• B. Cerebellum
• C. Occipital cortex
• D. Thalamus

Answer: (A)

The hippocampus is essential for forming and consolidating new memories, so it’s one of the first brain regions affected in Alzheimer’s disease. When the hippocampus is involved early, encoding new information becomes difficult, leading to noticeable memory impairment even in the early stages. The cerebellum governs movement, not memory formation; the occipital cortex handles visual processing; and while the thalamus acts as a relay in many circuits, it is not the primary memory-processing hub that is lost first in Alzheimer’s.
