One Night Without Sleep Increases Alzheimer's Protein in the Brain
Does One Night of Sleep Loss Increase Alzheimer’s Proteins in Your Brain?
Yes, and the effect is immediate and measurable. This groundbreaking study used PET brain imaging to show that just one night of sleep deprivation significantly increases amyloid-beta accumulation in the human brain—the same toxic protein that forms plaques in Alzheimer’s disease. The research demonstrates that sleep isn’t just about feeling rested; it’s actively protecting your brain from the protein buildup that may lead to dementia decades later.
