Another new study shows that oral health or properly taking care of your teeth may significantly help reduce the risk of having stroke. Researchers found that the oral bacteria, causing dental cavities or tooth decay, contribute to certain types of stroke.
In the study, published in the journal Scientific Reports, researchers discovered the link between hemorrhagic strokes and the oral bacteria, cnm-positive Streptococcus mutans. Hemorrhagic strokes occur when blood vessels in the brain rupture and cause bleeding.
The researchers hypothesize that S. mutans bacteria tend to bind to blood vessels weakened by age and high blood pressure. These bacteria may cause arterial ruptures in the brain, which may lead to small or large hemorrhages.
The team also found S. mutans can increase the number of cerebral microbleeds (CMB). These microbleeds are small brain hemorrhages that may cause dementia and intracerebral hemorrhage (ICH).
“This study shows that oral health is important for brain health,” said study co-author Dr Robert Friedland, from the University of Louisville, School of Medicine. “The study and related work in our labs have shown that oral bacteria are involved in several kinds of stroke, including brain hemorrhages and strokes that lead to dementia.”
“People need to take care of their teeth because it is good for their brain and their heart as well as their teeth,” he added.
The findings come from the analysis of health of patients entering a hospital for acute stroke. In patients who experienced ICH, 26 percent had S. mutans in their saliva, while 6 percent among patients with other types of stroke were positive for the bacterium.
However, Friedland noted about 10 percent of the general population have the S. mutans bacteria.
The researchers are now analyzing the role of oral bacteria in other diseases affecting the brain. Friedland said they’re now conducting study on how oral and gut bacteria contribute to neurodegenerative disorders like Alzheimer’s and Parkinson’s disease.
