Numerous studies dating back to 1998 have found chlamydia pneumonia in the brains of Alzheimer’s patients. Newer studies report a retinal scan can detect Alzheimer’s disease decades before symptoms develop, because changes in the vessels in the back of the eye correlate with changes in the brain in Alzheimer’s disease. It seems apparent that if a patient has a positive blood test for chlamydia pneumonia, and a positive retinal scan suggesting Alzheimer’s, early treatment of chronic chlamydia pneumonia could benefit the patient in preventing, delaying, or treating Alzheimer’s.

It is time to move past repeating more research studies identifying chlamydia pneumonia in Alzheimer’s patients, and move toward studies determining the benefit of early treatment of chlamydia pneumonia in patients who have a positive chlamydia pneumonia blood test, and findings suggestive of early Alzheimer’s on a retinal scan.
