Sleeping and Alzheimer’s

While there is no certainty about whether taking sleeping pills would affect the onset of Alzheimer's, this study suggests that it "may" help. 

But the finding more broadly shows that there is a link between sleep and the flushing of plaque buildup in the brain. And that piece of information is really interesting and surely will lead to more and better research and treatments for (or more precisely prevention of) Alzheimer's.
