Brushing Teeth – Postpone Alzheimer's Disease

The researchers determined that gum disease (gingivitis) plays a key role in the development of Alzheimer's disease or not.

"We have found evidence based on DNA that gingivitis-causing bacteria can pass from the mouth to the brain," says researcher Piotr Mydel of the Broegelmanns research laboratory of the department of clinical sciences of the United States. University of Bergen (UiB).

The bacterium produces a protein that destroys nerve cells in the brain, resulting in memory loss and eventually Alzheimer's disease.

Mydel points out that the bacteria is not the only cause of Alzheimer's disease, but that the presence of this bacterium greatly increases the risk of developing the disease and is also implicated in a faster progression of the disease. However, the good news is that this study shows that there are some things you can do yourself to slow down Alzheimer's.

"Brush your teeth and use dental floss". Mydel adds that it is important, if you have gingivitis and you have Alzheimer's disease in your family, to regularly go to your dentist and brush your teeth well.

Researchers have already discovered that the bacteria that cause gingivitis can move from the mouth to the brain, where the harmful enzymes that they excrete can destroy nerve cells in the brain. Now, for the first time, Mydel has DNA evidence of this process from the human brain. Mydel and his colleagues examined 53 affected people and discovered the enzyme in 96% of cases. According to Mydel, this knowledge offers researchers a new possible approach to fighting Alzheimer's disease.

"We have succeeded in developing a drug that blocks the harmful enzymes of the bacteria, thus delaying the development of Alzheimer's, and we plan to test this drug later this year," says Piotr Mydel.

• Bacteria Porphyromonas gingivalis (P. gingivalis) is one of the main causes of gum infection.
• The bacterium causes chronic infection of the gums, but can move to the brain where it can damage nerve cells in the brain.
• About 50% of the population has this bacteria in one form or another.
• About 10% of people with this bacteria will develop severe gum disease, loose teeth and an increased risk of developing Alzheimer's disease.
• In addition to Alzheimer's disease, the bacteria is linked to rheumatism, COPD and cancer of the esophagus.
