Sleeping poorly or not getting enough rest may result in a type of brain abnormality associated with Alzheimer’s disease, a study showed.
Brain images of adults with an average age of 76 found that those who said they slept less or poorly had increased build-up of beta-amyloid plaques, one of the hallmarks of Alzheimer’s, according to research published today in JAMA Neurology. None of those in the study had been diagnosed with the disease.
