Poor rest raises the levels of toxic proteins in the brain that can cause memory-robbing disease.
A recent tudy found that a night without sleep increased levels of beta-amyloid in the brain.
People with mild memory loss have 21% more beta-amyloid than healthy people, while those with Alzheimer’s disease have 43% more beta-amyloid, experts say
Sleep is vital in clearing away beta amyloid , which can form clumps in the brain, sleep deprivation may raise the risk of getting Alzheimer’s disease. Just one sleepless night has been found to cause the build-up of a protein linked to the devastating condition.
A study of 20 people, found a night without sleep increased the beta-amyloid protein in part of the brain by five per cent.People with mild memory loss have 21 per cent more beta-amyloid in their brains than healthy elderly people, while those with Alzheimer’s disease have 43 per cent more beta-amyloid.
While previous studies have shown similar brain changes in mice, this is the first to show brain changes linked to Alzheimer’s after a sleepless night in the human brain.
