## In brief

- Johns Hopkins scientists report brain scans showing two memory- and emotion-related regions shrinking before the hippocampus.
- The shrinkage may appear up to a decade before memory loss begins, according to the source summary.
- The findings are described as hidden warning signs of Alzheimer's disease.

## Why it matters

If these regions show changes years before memory symptoms, they could become targets for earlier detection and for studying the disease before clinical decline.
