The bacteria in your mouth can affect more than just your gums and teeth. They might also impact your brain.
In a study with 55 people who had mild cognitiveimpairment (MCI), those with more bacteria from the Neisseria group had better memory and attention skills.
Even among 60 people without memory problems, having lots of Neisseria helped improve memory scores.
Researchers from the University of Exeter say that encouraging good bacteria in the mouth may help slow down memory loss. This can be done with probiotics or prebiotics that help good bacteria grow.
Other studies show poor oral health can lead to memory problems. Some harmful bacteria from gum disease have even been found in the brains of people with Alzheimer’s.
In summary, having a balance of good bacteria may keep our brains healthy.
