However, this imbalance in oral bacteria was not associated with another Alzheimer’s biomarker called tau.
The study, published in the journal
Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, adds to the growing evidence of a connection between periodontal disease (gum disease) and Alzheimer’s. Periodontal disease which affects 70% of adults 65 and older, according to CDC estimates is characterized by chronic and systemic inflammation, with pockets between the teeth and gums enlarging and harboring bacteria.
“To our knowledge, this is the first study showing an association between the imbalanced bacterial community found under the gumline and a CSF biomarker of Alzheimer’s disease in cognitively normal older adults,” says Angela Kamer, associate professor of periodontology and implant dentistry at New York University College of Dentistry and the study’s lead author.

Washington [US], April 12 (ANI): Older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid-beta, a key biomarker for Alzheimer's disease in their cerebrospinal fluid, according to new research by the New York University. However, this imbalance in oral bacteria was not associated with another Alzheimer's biomarker called tau.
Imbalanced bacterial community in the gums linked to Alzheimer s disease biomarker
Older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid beta a key biomarker for Alzheimer s disease in their cerebrospinal fluid (CSF), according to new research from NYU College of Dentistry and Weill Cornell Medicine. However, this imbalance in oral bacteria was not associated with another Alzheimer s biomarker called tau.
The study, published in the journal
Alzheimer s & Dementia: Diagnosis, Assessment & Disease Monitoring, adds to the growing evidence of a connection between periodontal disease (gum disease) and Alzheimer s. Periodontal disease which affects 70 percent of adults 65 and older, according to CDC estimates is characterized by chronic and systemic inflammation, with pockets between the teeth and gums enlarging and harboring bacteria.
