naps are beautiful and as an adult, we always wish we could take one several times a day.
But those desires and that feeling of sleep during the day could be a sign of Alzheimer’s.
According to a study by the Johns Hopkins Bloomberg public health school, feeling excessively sleepy during the day could be a sign of increased risk for the brain pathology of that disease.
Older adults who felt sleepy during the day when they wanted to be awake were shown to be almost three times more likely to have deposits of beta-amyloid, the protein that accumulates in the brain as part of Alzheimer’s pathology.
The study was published in the journal Sleep, and the team used data from the Longitudinal Neuroimaging Study of Baltimore Aging to more closely examine daytime sleepiness levels and nap habits of 124 cognitively healthy male and female participants.
The researchers then compared that information with the results of the PET and MRI scan an average of 16 years later.
Thus, the finding was that people who said they often felt sleepy during the day were almost three times more likely to have deposits of beta-amyloid; however, nap habits were not significantly related to beta-amyloid deposits.
While it is not a direct correlation, researchers do see the results as further evidence that sleep problems and Alzheimer’s pathology may be connected, as we explain here
A single night of insomnia could cause you Alzheimer’s, here the explanation
That’s right, it was shown that if you sleep little you increase the levels of toxic proteins in the brain, these can cause diseases that steal memory.
One study found that a sleepless night increased levels of beta-amyloid in the brain. People with mild memory loss have 21% more beta amyloid than healthy people, for example.
So, sleep is vital to eliminate beta-amyloid and, in turn, lack of sleep can increase the risk of getting Alzheimer’s disease.
Only with a sleepless night could the risk be increased?
A study of 20 people found that one night without sleep increased beta amyloid protein by five percent.
While previous studies have shown similar brain changes in mice, this is the first to show brain changes in humans, related to Alzheimer’s after an insomnia night.
However, it is not clear whether the effects of a sleepless night are lasting or are only observed the next day.
Have you felt a little forgetful when you wake up in the morning?
Dr. Ehsan Shokri-Kojori, author of the study, explained: “Often the brain changes seen in animals do not replicate in humans, so this is interesting. A reasonable prediction based on these results would be that the bad sleeping habits create a risk for Alzheimer’s disease. “
The effects of sleep deprivation were observed in 20 healthy people between 22 and 72 years in the course of two nights. One group slept from 10 to 7 am, while in the second they stayed up all night.
Subsequently, their brains were scanned to show a “significant increase” in beta-amyloid in two brain regions vulnerable to damage in Alzheimer’s patients.
This is how they concluded that sleep plays an important role in eliminating things harmful to health.
Although, it cannot be assured that the disease is a product of lack of sleep, it is linked to the presence of beta-amyloid, characteristic of Alzheimer’s patients.
Do not think more, sleep has been said.
