Scientists have for the first time observed a mysterious mechanism of garbage removal in the brain that can help people fight against incurable dementia.
The team, led by neuroscientist Laura Lewis from Boston University (USA), has recorded the mysterious activity of cerebrospinal fluid (CSF) when people sink into the stage of deep dreaming.
In the latest brain scans of 13 23-33-year-old volunteers, the scientists were surprised to see something called "slow oscillating electric current" or "slow wave" beginning to appear when volunteers. enter a stage of deep sleep, not REM (ie fast eye movement, folk called dreaming). This slow oscillating current drives a portion of the blood out of the brain, making room for the cerebrospinal fluid that suddenly surges like waves, sweeping through our heads and cleaning up some of the toxic proteins that are the product Waste of living activities during the day.
Scientists have just come to the core of the sanity and mental refreshment you achieve after a good night's sleep, deep sleep and less dreaming - (photo courtesy of the Internet).
These are the proteins that have been shown to accumulate, leading to dementia, in particular the group, the most common of which is Alzheimer's.
That means Alzheimer's and dementia aren't exactly "no cure". It is true that human medicine, after a lot of efforts, has not been able to manufacture any specific treatment that can be applied to treat these incurable diseases. However, it is quite possible to consider the cerebrospinal fluid and the slow oscillating current as a natural remedy that everyone has in the body.
However, to use this "medicine" , you must really enjoy a happy sleep, less dreamy. That includes sleeping long enough, in a space that is comfortable enough for you to fall into a deep sleep phase.

Therefore, it can be said that sleep treatment is a direction to consider in combating memory loss, the incurable disease group is rising to a higher position in the ranking of causes of premature death.
According to the latest statistics of the World Health Organization (WHO), dementia is the 5th leading cause of death in the world but it is on a very strong upward trend.
The research has just been published in the journal Science.
