Häufige Bakterien im Auge im Zusammenhang mit kognitivem Verfall und Alzheimer entdeckt: Studie zeigt erstmals, dass Chlamydia pneumoniae (häufige Ursache von Lungenentzündung und Nasennebenhöhlenentzündung) die Netzhaut erreichen kann, wo es Immunreaktionen auslöst, die mit Entzündungen, Nervenzelltod und kognitivem Verfall verbunden sind.

**Common Bacteria Discovered in the Eye Linked to Cognitive Decline**
**Chlamydia pneumoniae—a common bacterium that causes pneumonia and sinus infections—can linger in the eye and brain for years and may aggravate Alzheimer’s disease**, according to a study from Cedars-Sinai. Published in Nature Communications, the discovery suggests this bacterium can amplify Alzheimer’s disease and points to potential interventions including inflammation-limiting therapies and early antibiotic treatment.
**The study shows for the first time that Chlamydia pneumoniae can reach the retina—the tissue lining the back of the eye—where it triggers immune responses linked to inflammation, nerve cell death and cognitive decline.**
To conduct the study, researchers used advanced imaging, genetic testing and protein analysis to examine retinal tissue from 104 individuals, some with normal cognition, some with mild cognitive impairment and some with Alzheimer’s disease.
They found significantly higher levels of Chlamydia pneumoniae in the retinas and brains of people with Alzheimer’s disease than they found in people with normal cognition. The higher the bacterial levels detected, the more severe the brain changes and cognitive decline investigators found.
Higher levels of the bacterium were more common in people who carried the APOE4 gene variant, a known risk factor for Alzheimer’s disease.

Interesting, so would a few rounds if antibiotics help?
All I get from these studies is that inflammation is the real killer.
Wasn’t there a story going around linking picking your nose to dementia?
After decades of searching it wouldn’t surprise me if alzheimer’s and every other major illness was caused by a pathogen of some kind.
Is this why I feel like I’ve mentally declined since my sinuses feel as though they have been inflamed for over a year?
