The syndrome of chronic fatigue (CFS) is most common in developed countries. It is a disease that can not be "cured" even by long rest. It is not right to confuse it with ordinary fatigue or lack of sleep. The emergence of the syndrome of chronic fatigue is associated with the development of neurosis of the central regulatory centers of the autonomic nervous system, which is caused by the inhibition of the activity of the zone responsible for inhibitory processes.
Contrary to studies, the results of which showed that the cause of chronic fatigue syndrome is the mouse retrovirus XMRV, a new study by American scientists proves that this is not so. Anything can cause a sluggish state, but the mouse virus has nothing to do with it.
The results of the new research of scientists published in the Internet publication of the American microbiological society "mBio" indicate that the chronic fatigue syndrome (myalgic encephalomyelitis), leading to loss of efficiency, and also accompanied by weakness and muscle pain, can not be caused by the retrovirus XMRV.
This conclusion was reached by three groups of researchers who submitted a detailed analysis of 147 tissue samples of patients with chronic fatigue syndrome and 146 samples of healthy people. For the purity of the experiment, the scientists themselves did not know which of the samples was taken from the sick people, and which was healthy.
Also, each group of specialists was given absolute freedom of choice in using methods for analysis in order to exclude possible claims and reproaches that, say, the correct method of research was simply not used.
As a result, it turned out that none of the teams found even traces of viruses suspected of causing a chronic fatigue syndrome.
In some samples of the test tissues, antibodies were detected that could "catch" the mouse virus, but this result was false due to the nonspecificity of immunoglobulins that reacted to foreign molecules.
In the group of the greatest risk are residents of large megacities, in which unbalanced emotional and intellectual load goes to the detriment of physical activity.
