Where does the memory reside that is damaged by Alzheimer's disease?

Where does memory lie in the brain? That's a terrific question. We think it resides all over the place. However, short-term memory appears to be associated with specific areas, like the hippocampus, which is an area deep in the temporal lobe. Some of the associated areas that are affected early on by Alzheimer's disease include the nucleus basalus of Meynert which is, again, in that same basal forebrain region. So, specifically, short-term recall, we think, is associated with the hippocampal structure, here.
