Gum infection may be behind Alzheimer
Highlights

A new study published in the journal Science Advances found that gum infection could be a potential risk factor of Alzheimers disease

A new study published in the journal ‘Science Advances’ found that gum infection could be a potential risk factor of Alzheimer’s disease.

The bacteria, Porphyromonasgingivalis, known as Pg, causes the gum infection chronic periodontitis, causing chronic inflammation and potential loss of teeth, reported CNN.

The same bacteria was further found in 51 out of 53 brain autopsies of Alzheimer’s disease patients, according to new research by Dr. Stephen Dominy and Casey Lynch, founders of the pharmaceutical firm Cortexyme.

The pharmaceutical company, which is focused on developing therapeutics to alter the course of Alzheimer's disease, funded the research.

The team also tested blocking the bacteria in mice by injecting small molecules targeting Pg, to inhibit it and found that it could reduce neurodegeneration in the brain, showing a potential new way to tackle Alzheimer's disease.

According to Lynch, her team’s publication “sheds light on an unexpected driver of Alzheimer’s pathology -- the bacterium commonly associated with chronic gum disease.”

Lynch further added that it also shows a “promising approach” to address the disease.
