Poor sleep in old age may be linked to the brain-clogging plaques thought to contribute to Alzheimer’s disease, new research suggests.
“Sleep appears to be a missing piece in the Alzheimer’s puzzle, and enhancing sleep may lessen the cognitive burden that Alzheimer’s disease imparts,” said study author Bryce Mander, a postdoctoral fellow at the University of California, Berkeley.

Still, the study findings hint at a major message regarding Alzheimer’s, said Mander, who works at the university’s Sleep and Neuroimaging Laboratory.
