UK Biobank data shows decline in brain health as such stroke may be exacerbated by poor oral health

Stroke linked to dental health issue according to UK Biobank data

An increased likelihood of white matter hyper intensities and a 43% rise in brain micro structural damage were linked to a hereditary susceptibility to oral health issues.

The study adds to the growing body of research linking a higher risk if neurological problems to poor dental health. According to a preliminary study that will be presented at the International Stroke Conference 2023 of the American Stroke Association, maintaining good dental health may also improve brain health.

The conference, which will take place from February 8~10, 2023, in Dallas and inline, is the foremost gathering of scientists and doctors who are interested in the study of stroke and brain health.

Studies have revealed that oral health issues such gum disease, missing teeth, and other oral health indicators, as well as improper brushing techniques and a failure to remove plaque, all raise the risk of stroke.

According to the American Stroke Association, stroke is the fifth largest cause of death and disability in the US. Gum disease and other issues with oral health are connected to heart disease risk factors and other illnesses including high blood pressure.

By brain health, we mean the functional status of a person’s brain, which we are now able to understand better using neuro imaging tools such as magnetic resoNance imaging or MRI.

Studying oral health is crucial since it’s a common problem and a risk factor that can be readily changed. Everyone may successfully improve their dental health with little effort and expense.

A person’s capacity to recall information, think clearly, and operate in daily life is all impacted by healthy lifestyle choices, just as they do the risk of heart disease and stroke.

According to the American Stroke Association, a branch of the American Heart Association, three out of every five Americans will have a brain disorder over their lifetime.

In this study, researchers examined the possible relationship between dental health and brain health in nearly 40,000 persons(46% males, average age 57 years) without a history of stroke who were registered in the UK Biobank between 2014 and 2021.

Managing oral care with little effort and expense is worth

The impact of these 105 genetic risk factors for poor oral health and brain health was assessed, and participants were checked for 105 genetic variations known to predispose people to developing cavities, using dentures, and losing teeth later in life.

White matter hyper intensities, or accumulated damage in the brain’s white matter, which may impair memory, balance, and mobility, and microstructual damage.

Or the degree to which the fine architecture of the brain has changed in comparison to images for a normal brain scan of a healthy adult of similar age, were two signs of poor brain health that were screened via MRI images of the participants’ brain.

The research revealed. A 24% increase in the number of white matter hyper intensities evident on the MRI scans indicated a larger burden of silent cerebrovascular illness in those who were genetically predisposed to cavities, missing teeth, or needing dentures.

A 43% shift in the microstructual damage scores observed on the MRI images demonstrated higher damage to the fine architecture of the brain in those with generally genetically poor dental health.

Microstructual damage scores are total-brain assessments fo the harm done to each brain region’s intricate design.

We should take special care to maintain good dental hygiene since it has effects that go well beyond the mouth because poor oral health may lead to reduction in brain health.

This study is preliminary, however, and additional data has to be acquired, ideally through clinical trials, to show increasing dental health in the community would have a positive impact on brain health, the author Rivier.

More research is needy

The investigation was constrained by the UK Biobank’s inclusion of solely residents of the UK, most of whom are of European ancestry(94% of participants in the UK Biobank claimed being white, compared with 6% who reports being mixed, Black Brit, Asian Brit, or other races).

More study with persons from various racial and ethnic origins is also required.

While the study’s findings do not show that dental hygiene enhances brain health, they are intriguing and should be taken into consideration, according to Joseph P. Broderick, a professor at the University of Cincinnati Department of Neurology and Rehabilitation Medicine.

With the exception of rare genetic diseases linked to poor dental health, such as damaged or missing enamel, environmental variables like smoking and medical illnesses like diabetes are considerably higher risk factors for poor oral health than any genetic marker, according to Broderck.

It is nevertheless wise to pay attention to your dental health and cleanliness. Smelly gum and teeth means inflammation in gum tissues and teeth, which is toxic and bothers other people. Dirty tongue is a collection of germs.

Additionally, genetic risk factors for other chronic health diseases including diabetes, hypertension, stroke, infections, etc, that are known to be linked to markers for brain imaging may overlap with genetic risk profiles for an elevated risk of dental health. Broderick didn’t take part in this investigation.
