Periodontitis, gum disease that may be linked to Alzheimer's disease

Mexico City.- A recent study published by the journal Advances in science, stresses that the chronic periodontitis, a type of gum disease, is linked to Alzheimer's disease.

The researchers looked at the brain tissue, O cerebrospinal fluid and the saliva of living and dead Alzheimer's patients; find the bacterium cause of chronic periodontitis, Porphyromonas gingivalis.

That people suffering from Alzheimer's are infected with this microorganism it is no coincidence; previously experiments with mice confirmed that the bacterium could travel from the mouth to the brain and showed that toxic protein which secrete destroys neurons.

After administering drugs that block these toxic proteins to diseased mice, the degeneration of their brains was disrupted.

The results of this study provide evidence that the presence of Porphyromonas gingivalis and gingipains in the brain play a central role in the pathogenesis of Alzheimer's disease, providing a new conceptual framework for the treatment of the disease. "

However, some people point out that cause and effect are probably being confused, since Alzheimer's patients are more vulnerable to infections in the brain.
