The result appears to be observational, so it shows an association rather than proof that eggs prevent dementia; confounding dietary or lifestyle factors could explain some or all of the link. The finding adds to a growing body of research suggesting everyday foods or simple supplements may influence brain aging, but randomized trials and biomarker studies are needed to confirm benefits and clarify mechanisms.
