US scientists have for the first time discovered that the bacteria responsible for bleeding gums can be transmitted from the mouth to the brain, thus increasing the risk of developing Alzheimer's disease later in life.
The researchers found that the symptoms of this bacterium causing gum disease in the brain of 51 out of 53 participants were suffering from Alzheimer's disease. The results suggest that those who brush their teeth properly can reduce the risk of dementia. The study revealed that Porphyromonas gingivalis, the leading cause of gum disease, was only able to reach the mouse brain six weeks after infection. The damage in brain memory centers of these mice could explain earlier evidence that people with long-term gum disease were 70% more likely to develop dementia.
Scientists believe that bacteria can cause Alzheimer's disease in humans after discovering the toxic enzymes produced by brain, cerebrospinal fluid and rodent games diagnosed with the disease. The study conducted by the American company "Corexyme", which states that bacteria play a "central role" in the development of Alzheimer's disease.
"This study is an important achievement to understand how to stimulate Alzheimer's disease and a new treatment underway," said Casey Lynch, general manager of the company.
It was suspected that oral bacteria could enter the bloodstream, entering cells believed to protect the brain and spreading over the brain for several years. Scientists have shown that they can move from the mouth to the brain in mice.
