Maybe you should rethink that all-nighter?

A new study published in Science hints at a connection between sleep (or lack thereof) and the development of Alzheimer’s disease.  In both mice and humans, amyloid-beta peptide levels rose during waking hours, but then fell again upon sleep.  Amyloid-beta plaques (like those found in the brains of Alzheimer’s patients) formed more readily in sleep-deprived mice.  Although certainly not a smoking gun, this research may indicate poor sleep patterns are a risk factor for development of Alzheimer’s disease.

…I think I’ll turn in early tonight…
