A recent study showed that people who define themselves as very sleepy during the day are almost three times more likely to develop Alzheimer’s disease. Alzheimer’s, which is a neurodegenerative condition, affects the brain and causes progressive memory loss. At the moment, there is no effective treatment to control this illness, but new research may well have found a way to prevent or at least slow its onset. According to them, sleeping during the day instead of the night could lead to Alzheimer’s disease.
Researchers have long known that sleep deprivation is common in Alzheimer’s disease patients
The study conducted by researchers at the prestigious John Hopkins University in the United States and published in the journal Sleep, adds that poor sleep quality could contribute to the development of Alzheimer’s disease.
On the other hand, the research showed that people who sleep a lot during the day are almost three times more likely to develop Alzheimer’s disease later in life. The cause is the appearance of the beta-amyloid protein buildups during excessive diurnal sleep.
To achieve this result, the researchers used data from a long-term study launched in 1958 by the National Institute on Aging (NIA) that monitored the health of thousands of volunteers as they aged.
According to the research, those who were sleeping during the day had almost three times more beta-amyloid protein deposits in the brain than the others.
Quality sleeping at night would reduce the risks of Alzheimer’s disease
The researchers pointed out that the mechanism that makes these proteins buildups to occur is related to sleeping during the day but how exactly is that working is yet to be cleared up.
However, a probable explanation, according to the researchers, is that poor quality sleep leads to drowsiness and the production of more beta-amyloid proteins. Accordingly, good night sleep could be an effective way to prevent the onset of Alzheimer’s disease.
