Toronto researchers have found that volume loss within the hippocampus best discriminated people with:
A) Early stages of Alzheimer
B) Korsakoff's syndrome
C) Late stages of dementia
D) Chronic depression

Question

Quizplus · Accepted Answer

The hippocampus is a region of the brain important for memory and is one of the earliest regions to be affected by Alzheimer's disease. Therefore, volume loss within the hippocampus is a hallmark feature of early stage Alzheimer's disease. Korsakoff's syndrome is a disorder typically caused by alcohol abuse that also affects memory, but it primarily involves damage to the thalamus and medial temporal lobe rather than just the hippocampus. Late stages of dementia may involve widespread brain damage and atrophy, not just in the hippocampus. Chronic depression may also involve changes in brain volume, but not specifically within the hippocampus.
