Over the last few years, several scientists have pointed to a little-known hypothesis about the origin of Alzheimer’s, according to his theory it is not just a disease, but an infection. Now, a new study published in Science Advances reinforces this theory and does so by linking this degenerative disease to an unexpected origin: a gum disease.
Jan Potempa, a microbiologist at the University of Louisville, has discovered ‘Porphyromonas gingivalis in the brains of dead Alzheimer’s patients. It is the pathogen that causes chronic periodontitis, known as gum disease and is not the first time the two diseases have been associated, as a 2010 study already assessed this possibility.
