Deep sleep for long periods delays the onset of dementia
Scientists have discovered that getting a good night's sleep can delay the onset of dementia later in life.
Sleep is the "crystal ball" to predict the possibility of developing Alzheimer's disease or dementia in the future, according to the researchers.
According to the British "Mirror" website, a relationship has been found between deep sleep in frequent and delayed the onset of dementia, because sleep slows down the formation of a toxic plaque in the brain called beta-amyloid.
And the brain washes itself during deep sleep, which prevents the formation of this plaque that is associated with Alzheimer's.
The study, conducted at the University of California, Berkeley, California, looked at the sleep quality of 32 healthy adults in their 60s, 70s and 80s.
