Alzheimer’s disease is one of the most devastating conditions affecting older adults, slowly taking away memories and independence.
For years, scientists have searched for answers—what causes it, and can it be prevented?
While we often think of Alzheimer’s as a brain-related disease, recent research suggests that the answer might not start in the brain at all.
Instead, it could begin in a place most of us wouldn’t expect—our mouths.
At The GrayVine, we know how important it is to stay informed about health risks, especially those that could impact cognitive well-being.
That’s why we’re exploring a theory gaining attention in the scientific community: Could gum disease play a role in Alzheimer’s? The connection may surprise you.
A groundbreaking study published in 2019 has shed light on a possible link between Alzheimer’s disease and a common bacterial culprit: Porphyromonas gingivalis, the main pathogen behind chronic gum disease (periodontitis).
Led by microbiologist Jan Potempa from the University of Louisville, researchers discovered traces of P. gingivalis in the brains of individuals who had Alzheimer’s.
What makes this even more concerning? The bacteria weren’t just present—they were found alongside increased levels of amyloid beta (Aβ), the sticky proteins associated with Alzheimer’s disease.
This discovery wasn’t limited to human studies; researchers found that mice infected with P. gingivalis also developed brain colonization and a buildup of Aβ.
The pharmaceutical startup Cortexyme, which coordinated the study, has been investigating the role of infections in Alzheimer’s development.
Co-founder and lead researcher Stephen Dominy explained that while scientists have long suspected a connection between infections and Alzheimer’s, this is the first time solid evidence directly ties P. gingivalis to the disease.
For years, researchers have debated a critical question: Does gum disease contribute to Alzheimer’s, or does dementia lead to poor oral hygiene?
This study offers a compelling argument that gum disease may not just be a consequence of Alzheimer’s—it could be a driving factor.
One of the most revealing findings was the presence of gingipains, toxic enzymes released by P. gingivalis, in the brains of individuals who never had an Alzheimer’s diagnosis.
This suggests that the infection could be an early event in the disease process, occurring long before noticeable cognitive decline begins.
Additionally, these harmful enzymes were found alongside key Alzheimer’s markers, including tau proteins and ubiquitin.
The fact that P. gingivalis was detected in middle-aged individuals without dementia raises an important question: Could preventing or treating gum disease reduce the risk of developing Alzheimer’s?
While these findings are promising, they are just the beginning. There is still much to learn about how infections like P. gingivalis influence Alzheimer’s disease and whether this connection could lead to new treatments.
Cortexyme has developed an experimental drug, COR388, designed to block the toxic effects of P. gingivalis.
In early research, this compound showed potential by reducing the bacterial load in brain infections and decreasing the buildup of harmful amyloid-beta plaques.
The Alzheimer’s research community remains cautiously optimistic.
With no new effective dementia treatments in over 15 years, exploring different approaches—including those targeting bacterial infections—is a crucial step forward.
David Reynolds, Chief Scientific Officer at Alzheimer’s Research, emphasized the importance of testing as many potential treatments as possible in the fight against this disease.
As we age, taking care of our health—including oral health—becomes even more important. Here at The GrayVine, we encourage our community to be proactive.
