Study: Poor sleep increases risk for Alzheimer’s

The Huffington Post reports that research presented at the Alzheimer’s Association International Conference suggests that “poor sleep may increase people’s risk of Alzheimer’s disease.”The researchers think that poor sleep spurs beta-amyloid, “a brain-clogging gunk that in turn further interrupts shut-eye.”

Researchers arrived at this conclusion after giving memory tests and “PET scans to 26 cognitively healthy volunteers in their 70s to measure build-up of” beta-amyloid.

The investigators found that “the more amyloid people harbored in a particular brain region, the less deep sleep they got – and the more they forgot overnight.”

These findings were presented at a medical conference. They should be considered preliminary as they have not yet undergone the “peer review” process, in which outside experts scrutinize the data prior to publication in a medical journal.
