I know Rebecca has mentioned this in her blog, but there may be links between inflmammation, dementia and actual urinal loss due to poor oral hygene.

"Infections in the gums that can lead to tooth loss may release inflammatory substances, which in turn will enhance the brain inflammation that cause neuronal death and hasten memory loss," she said in a news release from the journal's publisher. "The loss of sensory receptors around the teeth is linked to some of the dying neurons."

Seems ironic - your teeth problems cause you to lose neurons which limit your ability to feel pain in your mouth, which increases those issues.

spot the easter egg?
