Up to 12 percent of Americans may get Alzheimer's disease, current statistics say.  In the quest to prevent Alzheimer's, or at least make it manageable like diabetes, a group of researchers are working on a nasally-delivered vaccine that promises to protect against Alzheimer's.  Bonus: It may help prevent strokes also.

The new vaccine repairs vascular damage in the brain by using the body's own immune system and, in addition to its prophylactic effect, it can work even when Alzheimer's symptoms are already present, according to the paper in Neurobiology of Aging.

SKIPTON, England, March 1, 2011 - Grotty old beds could be behind a growing epidemic of 'toxic sleep'. 

 A new Sleep Council survey just in time for National Bed Month shows nearly half of us are getting just six hours sleep or less a night. And an alarming four out of five people complain of disturbed or inadequate - 'toxic' - sleep. 

The survey was conducted online by Pollab Ltd between January 26 - 27 2011. 1,030 UK adults (aged 16+) were questioned, the sample being broadly representative of the UK population and demographically broken down by age, gender, region and marital status.
