A New Infectious Mechanism for Alzheimer’s?

"A large multicenter team reports that Porphyromonas gingivalis, which is the key pathogen in gingivitis (gum disease) may be the actual causative agent in Alzheimer’s, which is a bold claim indeed. But they have several lines of evidence to back it up, and it’s a hypothesis that has to be taken seriously."

Since it is claimed that Indian people have a lower occurrence of Alzheimer, possible due to the consumption of turmeric, I looked up a link between gum disease and tumeric and found this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3498709/
