In recent years, an increasing number of scientific investigations have backed an alarming hypothesis: Alzheimer’s disease may not be merely a condition of an aging brain, but the product of infection.

While the exact mechanisms of this infection are something researchers are still trying to isolate, numerous studies suggest the deadly spread of Alzheimer’s goes way beyond what we used to think.

One such study, published in 2019, suggested what could be one of the most definitive leads yet for a bacterial culprit behind Alzheimer’s, and it comes from a somewhat unexpected quarter: gum disease.
