(The Hill) Gum disease may lead to the development of Alzheimer’s, according to a new study.

A team of scientists led by the pharmaceutical company Cortexyme found “strong evidence” of a link between Alzheimer’s and Porphyromonas gingivalis, the key bacteria in gum disease, University of Louisville researcher Jan Potempa said.

Potempa added that “more research needs to be done” to show causation, rather than simply correlation, between gum disease and Alzheimer’s.
