Common pneumonia bacterium may fuel Alzheimer’s disease

A common bacterium best known for causing pneumonia and sinus infections may also play a surprising role in Alzheimer’s disease. Researchers found that Chlamydia pneumoniae can invade the retina and brain, where it sparks inflammation, nerve cell death, and the buildup of amyloid-beta—the hallmark protein linked to Alzheimer’s. Higher levels of the bacterium were found in people with Alzheimer’s, especially those carrying the high-risk APOE4 gen…

How might pneumonia bacteria link to Alzheimer’s?

A surprising suspect in long term brain disease research Scientists are reporting evidence that a common pneumonia causing bacterium may play a role in processes associated with Alzheimer’s disease and that changes in the eye could offer an early signal. The finding does not yet prove the…
