London - Sleepness nights could be an early sign of Alzheimer’s disease.
Scans showed that brains of people who were sleepy during the day contained higher levels of the protein beta-amyloid.
A hallmark of Alzheimer’s, it interferes with brain function, disrupting memory, mood and behaviour.
Researchers from the University of Wisconsin-Madison looked at the sleep quality of 98 people aged between 50 and 73.
Those who slept badly or were sleepy during the day were found to have more beta-amyloid in areas of the brain Alzheimer’s affects.
The study, presented at the American College of Neuropsychopharmacology’s annual conference, is one of several recent pieces of research to make the link. - Daily Mail
