The paper identifies a subset of older adults with stable memory performance over time, linking this stability to brain structure and showing it is often transient rather than consistent.

This study examines how brain volume differences in adults are stable from young adulthood or change with age, using MRI data from 8,311 individuals.

The paper shows cortical thickness changes occur years before high amyloid levels in Alzheimer's disease, challenging the view that amyloid is the first imaging marker.
