According to the Daily Mail, new research suggests that getting a good night’s sleep may be the key to improving memory later in life.
People who manage fewer than four hours a night or who wake regularly are more at risk of developing dementia.
Poor quality sleep and restless nights are thought to trigger the formation of plaques on the brain linked to Alzheimer’s disease (AD).
Previous studies have shown disrupted sleep is common in people with the condition and could play a role in developing the disease.
New research shows sleeping well could prevent the development of plaques – abnormal clusters of protein fragments – associated with Alzheimer’s.
It is also thought to play a key role in maintaining grey matter health in regions of the brain sensitive to ageing and memory.
People who sleep poorly are more likely to have a build-up of amyloid-beta (Ab) – a sticky protein which clumps together to form damaging plaques.
