Sleep Deprivation Causes Alzheimer’s Protein to Build up in the Brain

Our brains, like everything else about our bodies, change as we age. But the changes that happen to the Alzheimer’s brain are not part of the normal aging process. Researchers have struggled to understand the underlying mechanisms that lead some people to develop Alzheimer’s. Now a new study published in Science has linked poor sleep to an abnormal build-up of an Alzheimer’s-promoting protein in the brain.
