Getting a good night’s sleep and improving our ‘sleep health’ could be a positive step in preventing or reducing the risk of developing dementia.
A recent study confirms that chronic sleep problems predispose people to the development of dementia (1). This study shows that the protein tangles characteristic of Alzheimers build up when people have broken or poor quality sleep. The build up of protein is apparent even after sleeping poorly for one night (2).
This finding is in line with earlier research showing the relationship between Non-REM sleep, protein build up and memory impairment (3).
