Your eyes may reveal your Brain's future: new study tests early warning signs

This study looks at 100 healthy adults over 60 to see if brain scans and eye-tracking tests can predict memory changes. Researchers focus on a small brain area called the locus coeruleus, which is linked to early Alzheimer's changes. Participants will have MRI scans and do computer tasks while their pupils are tracked, with a follow-up after 18 months. No treatment is given; the goal is to better understand aging and find early markers of cognitive decline.
