Bacteria caused by gum disease linked to dementia

Posted: Updated:

Research out of the United Kingdom has shown that bacteria that is caused by gum disease can get into the brain, and scientists believe that bacteria may be related to dementia.

Researchers found signs of a bacteria previously linked to gingivitis in four out of 10 samples of brain tissue from Alzheimer's patients.

This bacteria was not found in any brain samples taken from people who never suffered from dementia.

These findings do not prove that gum disease causes dementia, but it does indicate a possible link.

Previously, gum disease has been linked to cardiovascular problems.
