Can oral bacteria protect against Alzheimer's?

 Can oral bacteria protect against Alzheimer's?

According to the University of Exeter, there are some bacteria in the human mouth that can be a factor in the changes that occur in the brain with increasing age.

Oral bacteria can protect against Alzheimer's, a brain problem. Similarly, experts claim.

Alzheimer's disease is a 'neurodegenerative' condition. In which brain cells start to deteriorate. This causes difficulty in memory, thinking ability and daily activities.

According to experts from the University of Exeter, there are some bacteria in the human mouth that can be a factor in the changes that occur in the brain with increasing age.

Study author Dr. Joanna L. Hurrex says, 'During a study conducted by the University of Exeter, such types of bacteria have been discovered, which are associated with excellent memory and consciousness, while many other bacteria are associated with weak brain and Alzheimer's disease. Alzheimer's disease can be detected before you have it or go to the doctor for a check-up.

The study is still in its early stages. However, the researchers who led the study are now working on another study. They are investigating the possibility that healthy foods, such as leafy green vegetables, can boost the number of bacteria in your gut, which can affect brain health.

Why nitrates?

Professor Anne Corbett, co-author of the study, said: "Our findings are very important. Some bacteria are good for the brain, some are not. In this way, changing the bacteria in your gut to help the brain could help prevent dementia. This could be done through dietary changes, probiotics, oral health and targeted therapies."

The study involved 115 people over the age of 50. Their brains had already been tested for another project.

Alzheimer's

The researchers divided them into two groups. One group included people who had no brain problems. While the second group included people with mild brain problems.

Some bacteria are helpful for brain function and some are not. In this case, it is possible to prevent dementia from the mouth by changing the bacteria as a treatment. This is possible through dietary changes, probiotics, oral health and targeted treatments.

People in both groups were asked to rinse their mouths and samples were collected and the bacteria found in it were studied.

According to the university, people with high numbers of Neisseria and Haemophilus bacteria in their mouths were found to have better memory, alertness and the ability to perform complex tasks.

Similarly, people with memory problems had higher numbers of Porphyromonas bacteria. Bacteria from the Prevotella group are associated with low nitrates. It is commonly found in people suffering from Alzheimer's disease.

Foods that can protect against Alzheimer's

Dr. L. Hurex says, "To prevent Alzheimer's, we advise people to eat beetroot, spinach, green vegetables and enough salad every day and to eat less alcohol and high-sugar foods."

Green vegetables are the largest natural source of nitrates.

Researcher and professor Anne Vanhatalo says, "In the future, when a patient comes to a doctor for a consultation, a sample can be taken from their mouth. So that it can be tested to determine whether they are at risk of dementia and Alzheimer's."
