Do you get cold sores? I do, so I know how much of a pain in the you-know-what they can be. And if it's not bad to enough to be cold sore-prone, there's more bad news for sufferers -- we're more likely to develop Alzheimer's later in life. The reason? The infection seems to radically increase the production of amyloid, the toxic protein that clogs the brain cells in Alzheimer's sufferers.

Armed with these new findings, researchers will try to look at how cold sore drugs may lessen or eradicate this connection. But in the meantime, all we cold sore folks can do is wait. And those who don't get cold sores should take precautionary measures to make sure they don't get the virus.
