In a new study out Wednesday, scientists reveal yet another reason to keep up on dental hygiene. Bacteria that cause a common yet largely preventable gum infection may also play a role in Alzheimer’s disease. The discovery also offers hope for a treatment that could slow neurodegeneration.
“There were many clues in the [features of Alzheimer’s disease] that an infection is at work,” said Casey Lynch, an entrepreneur and co-founder of Cortexyme, a biotech company headquartered at the Verily Life Sciences campus in South San Francisco, who led the new research. “Many of the genetic risk factors for Alzheimer’s are related to immune system function,” she added, which suggests “immune system dysfunction might put people more at risk.”
