Nose injuries may let bacteria reach the brain, hinting at Alzheimer’s link in mice
TL;DR
Australian researchers in Griffith University show, in mice, that Chlamydia pneumoniae can travel from the nasal cavity to the brain via the olfactory and trigeminal nerves, with amyloid-beta deposits forming within days. Nasal epithelial injury increased bacterial load and brain involvement, but there are no human data yet and the causal role for Alzheimer's remains unproven; a human study is planned.
