Research finds oral bacterial imbalance linked to Alzheimer’s disease
In the light of increasing evidence of a link between periodontitis and Alzheimer’s disease, researchers at the New York University (NYU) College of Dentistry and Weill Cornell Medicine have revealed that older adults with a preponderance of harmful bacteria in their mouth have shown greater evidence of amyloid beta, of the main biomarkers for Alzheimer’s disease, in their cerebrospinal fluid.
However, according to an article in Dentistry Today, this imbalance between harmful and bacteria “was not associated with another Alzheimer’s biomarker called tau.”
Speaking about the results of their research, lead author Angela Kamer, DDS, PhD, associate professor of periodontology and implant dentistry at the NYU College of Dentistry had this to say:
