A team of UC Berkeley neuroscience researchers reports that there is a correlation between poor, fragmented sleep and the buildup of toxic plaque in people's brains known to mark the onset of dementia. "We have found that the sleep you're having right now is almost like a crystal ball telling you when and how fast Alzheimer's pathology will develop in your brain," said study senior author Matthew Walker, a University of California, Berkeley professor of psychology and neuroscience.
