Italian research has found a link between insomnia and dementia such as Alzheimer's: cerebral activity disorders cause astrocytes in the brain to "eat" its friends!

Sleep helps you get a little refreshed as it launches a "cleansing" mechanism in the brain that cleans up damaged, worn brain cells. In a new study published in the Journal of Neuroscience, Dr. Michele Bellesi from the University of Marche Polytechnic (Ancona, Italy) found that sleep deprivation does not only weaken the mechanism, but also makes it active. overactive.

In the human brain, star cells play a number of roles: protecting brain structures, providing brain nutrients, coordinating neural signals, and eliminating damaged cells.
Stellar astigmatism is so overactive that instead of just cleaning things up, they wipe out organizations that do not even sleep in the brain. The food that is eaten is mainly synapses, which are the connections between the neurons that help to deliver the nerve signals.
In many previous studies, the loss of synapses and other nerve cells was a major cause of dementia - dementia such as Alzheimer's.
To reach this conclusion, Dr. Michele Bellesi and his colleagues monitored four groups of mice: one sleeping 6-8 hours comfortably, the second being awake for a sudden wake, the third Insomnia all night, the 4th group did not sleep for 5 consecutive days.
The fact that astrocytes "eat" healthy organs have been observed very clearly in sleep groups. The more serious the loss of sleep, the tedious and disorganization of the astigmatism.
Star cells appeared dense in the location of synapses, up to 13.5% in mice suffering from insomnia, 8.4% in mice who did not sleep one night, 7.3% In children who are awake and only 5.7% of children are getting enough sleep.
Further studies suggest that insomnia can lead to similar effects in humans but scientists are still learning more about whether getting enough sleep can help reverse the situation, preventing Alzheimer's disease.
Alzheimer's and other dementias are becoming the leading cause of early death in many countries, prompting scientists and physicians around the world to race for prevention and treatment.
