Description
Oana Dumitrascu and co-authors present a 2025 study on amyloid plaques around eye blood vessels. The retina offers a window on brain decline. A laser scan can show vessel changes and amyloid, the protein that clumps in Alzheimer's disease. The team scanned 34 adults with normal or impaired thinking, plus brain imaging and standard tests.
Plaques hugged arteries more than veins across the group. In people with low test scores, plaques near second-order veins ran higher. Plaque counts in the smallest branches tracked smaller memory centers in the brain. They also tracked more white matter damage spots. The authors say retinal amyloid patterns mirror brain changes. Eye scans might one day flag decline without brain imaging.
