Description
Darlingtina Esiaka and co-authors link brain volumes to memory speed, with a sex twist, in a 2025 study. The amygdala, a small brain hub for emotion, shrinks early in Alzheimer disease. That shrinkage may disturb memory networks as well. The team tested how amygdala size relates to recalling non-emotional items.
Older adults from a Kentucky Alzheimer center did a delayed matching task inside a brain scanner. Larger left amygdala and hippocampus volumes went with faster replies on the second round. The link between volume and speed differed by sex in the analysis. Such contrasts may matter for tracking early decline. The study adds the amygdala to the list of regions watched in aging memory research.
