Researchers say they have found evidence linking bacteria that causes gum disease to Alzheimer's disease.
Researches examined brain tissue from patients with Alzheimer's and found toxic enzymes from the bacteria in more than 90 percent of the samples.
Scientists believe this may be the case after their study found further evidence of the link between bacteria in a common type of gum disease and people with dementia.
Researchers say their findings offer hope for a new way of tackling the illness, for which there is no cure and no effective treatments.
