From the Ted Talk by Matt Walker: What's the connection between sleep and Alzheimer's disease?
Unscramble the Blue Letters
Now, some of this discussion may sound perhaps a little depressing. We know that as we get older in life, our sleep seems to typically dicnele, and our risk for Alzheimer's generally increases. But I think there's actually a silver lining here, because unlike many of the other factors that are associated with aging and Alzheimer's disease, for example, changes in the pcyhsial structure of the brain, those are fiendishly dciilfuft to treat and medicine doesn't have any good wholesale acarepophs right now. But that sleep is a missing piece in the explanatory plzzue of aging and Alzheimer's disease is exciting because we may be able to do something about it.
