For Healthy Brain Take Care Of Oral Health Well

A new study says that the oral bacteria may be involved in different kinds of stroke such as brain hemorrhages and strokes that may lead to dementia.

Stroke is characterized as either ischemic or hemorrhagic strokes that involves blocking of one or more blood vessels reaching the brain or the one in which blood vessels in brain rupture.

Study shows that the oral health is important for the brain health. According to study co-author Robert Friedland from University of Louisville School of Medicine in the US you should take care of your teeth as it is good for the brain, heart as well.

Freidland along with the researchers at the National Cerebral and Cardiovascular Center in Osaka, Japan observed stroke patients for getting a better picture of the relationship between hemorrhagic stroke and oral bacteria.  

Those patients who experienced intracerebral hemorrhage (ICH), about 26 percent were found to have a specific bacterium present in their saliva, known as cnm-positive S. mutans and those with the other type only 6 percent were tested positive for the bacterium.

The MRIs of participants was also evaluated by the researchers to know the presence of cerebral microbleeds (CMB), small brain hemorrhages that are responsible for causing dementia and often underlie intracerebral hemorrhage.

They also found that the number of cerebral microbleeds are higher in participants with cnm-positive S. mutans bacteria than in those without it.It can therefore be concluded that the the S. mutans bacteria can bind to the blood vessels and may get weak by age and elevated blood pressure which lead to the arterial ruptures in the brain causing small or large hemorrhages.
