There's some new research that looked into how sleep protects against Alzheimer's. "A study published in the journal Science revealed that cerebrospinal fluid carries these waste products away from the brain during deep sleep, acting as a guard to cognitive function . . . There’s also mounting research to suggest that getting too little—or even too much—sleep could increase your risk for Alzheimer’s disease."
