There has been a link between heart disease and oral care now there could be a link between an oral bacteria and having a stroke. “In a study of patients entering the hospital for acute stroke, researchers have increased their understanding of an association between certain types of stroke and the presence of the oral bacteria (cnm-positive Streptococcus mutans). Robert P. Friedland, M.D., the Mason C. and Mary D. Rudd Endowed Chair and Professor in Neurology at the University of Louisville School of Medicine, was a co-author of the study, published online this month in Scientific Reports, a journal of the Nature Publishing Group.
In the single hospital study, researchers at the National Cerebral and Cardiovascular Center in Osaka, Japan, observed stroke patients to gain a better understanding of the relationship between hemorrhagic stroke and oral bacteria. Among the patients who experienced intracerebral hemorrhage (ICH), 26 percent were found to have a specific bacterium in their saliva, cnm-positive S. mutans. Among patients with other types of stroke, only 6 percent tested positive for the bacterium.
Strokes are characterized as either ischemic strokes, which involve a blockage of one or more blood vessels supplying the brain, or hemorrhagic strokes, in which blood vessels in the brain rupture, causing bleeding.”
