Retinal Bacteria May Signal Alzheimer's Progress
TL;DR
A Cedars-Sinai study finds Chlamydia pneumoniae in the retina—more abundant in people with Alzheimer's—where infection correlates with cognitive decline. Lab tests in neurons and animal models show infection-driven inflammation, neuron death, and amyloid-beta buildup, suggesting retinal infection could reflect brain pathology and serve as a noninvasive biomarker and potential treatment target, though causality is not proven.
