A new study presents new data that indicate the danger of lack of sleep and its role in the development of Alzheimer's disease.
Just one night without sleep leads to an increase in the concentration of protein in the blood, which contributes to the development of Alzheimer's disease. Scientists talk about this in an article published in the journal neurology,
Tau protein is normal in nerve cells. But the appearance of its abnormal form, along with deposits of protein beta-amyloid, causes Alzheimer's disease. Previously, scientists have already discovered that lack of sleep leads to an increase in the amount of beta-amyloid in the cerebrospinal fluid. It is known that with good sleep, the brain is cleared of proteins that lead to the disease.
“Our study shows that even in young healthy people, lack of sleep during one night leads to an increase in tau protein in the blood. This suggests that lack of sleep may possibly lead to the development of the disease over time, ”said Jonathan Cedernaes, neuropathologist at Uppsala University, author of the study.
In a new study, scientists observed 15 participants. After people were not allowed to sleep at night, the concentration of tau protein in their blood increased by an average of 17%. After normal sleep, this figure was approximately 2%.
Scientists point out that this is just a small study, so it does not allow us to say exactly what such an increase in tau protein in the blood can lead to.
“High blood levels may indicate that tau protein is being washed out of the brain or that it accumulates in the brain. Further research is needed to investigate this, ”Kedernes said.
Earlier we talked about what will happen to the body if you move a little and overeat for only one or two weeks.
