Bacteria in the mouth that can give traces of brain health


“We can predict if you have the Alzheimer’s gene even before thinking of going to the doctor,” says a study author in the United Kingdom.




Some bacteria found in the mouth can be connected to changes in brain function such as people who age, researchers say at the University of Exeter in the United Kingdom.

A study conducted by university researchers discovered that some types of bacteria were associated with the best memory and attention, while others were linked to cerebral health problems and Alzheimer’s disease.

“We can predict if you have the Alzheimer’s gene even before starting to have problems or think of going to the doctor for a diagnosis,” says Joanna L’aureux, the main author of the study.

The research is in the early stages, but researchers say that they are now studying whether to eat some healthy foods, such as green leaves rich in nitrates, can influence brain health by stimulating some bacteria.



The study had over 100 volunteers over the age of 50

For the co-author of the Anne Corbett studio, the implications of the results are profound.

“If some bacteria support brain function while others contribute to the decline, then the treatments that alter the balance of bacteria in the mouth can be part of a solution to prevent dementia,” he says.

“This can be through changes in the diet, in probiotics, in oral hygiene routines or even direct treatments.”

The study recruited 115 volunteers over 50 who had already performed cognitive tests in the context of another project.

The researchers divided them into two groups: one with people without declining brain function problems and others with patients with slight cognitive problems.

The participants of both groups sent saliva samples that were then analyzed and the populations of studied bacteria.



Studio analyzed champions from the participants

People who had large quantities of groups of bacteria Neisker AND Hemophile They had a better memory, attention and ability to perform complex tasks.

Who had the highest levels of bacteria Porfromonas They were people with memory problems.

Already the bacterial group Prevotella He was linked to the nitrite below, more common in people who brought the risk of Alzheimer’s disease risk, explains Heureux.

Although the study shows a correlation between bacteria and diseases, it is unable to demonstrate causality, that is, that has caused the other. This requires more research.

Further studies can lead to a future way to help diagnose the disease, according to researchers.

“In the future, we may collect these champions [da boca] as part of consultations The doctors and elaborate them to give an early indication if someone has a high risk of memory diseases “, says Vanhatolo years, a dean associated with research and the impact of research and impact.
