Gum Disease Linked to Alzheimer’s Development

Bloomberg News reports that gum disease may be linked to the development of Alzheimer’s disease. In a new study, researchers found that Porphyromonas gingivalis, a bacterium linked to gum disease, “traveled to the brains of people with Alzheimer’s disease.” Researchers revealed that signs of Porphyromonas gingivalis were found in “four out of 10 samples of brain tissue from Alzheimer’s patients, while no signs of the bug were found in 10 brains from people of similar age who never developed dementia.” The results support the theory that bacteria in the mouth can enter the bloodstream and reach the brain. One expert theorizes, “over time, the chemicals produced by the bacteria could build up and contribute to the development of Alzheimer’s”
