According to British scientists at Newcastle University, one of the reasons for the appearance of severe fatigue in people who have had Covid-19 may be reduced activity of areas of the cerebral cortex that cause problems with the nervous system, according to a study provided by medRxiv..

“The complaints of people who have recovered from coronavirus infection are in many ways similar to the complaints of patients with chronic fatigue syndrome.. The study of the state of the body in this category of people made it possible to establish a decrease in the activity of the cerebral cortex, both in those who had COVID-19 and those suffering from chronic fatigue syndrome,” the researchers report..

Almost everyone who has had a coronavirus infection has experienced post-COVID syndrome, which is manifested by rapid fatigue, hair loss, shortness of breath, exacerbation of various chronic processes.. Scientists attribute this development of events to the constantly high activity of the immune system against the background of the disease..

The possible causes and mechanisms contributing to the development of chronic fatigue in survivors of COVID-19 were reported by British doctors who studied the health status of 37 patients who experienced these disorders for several months after recovery.. During the study, the participants underwent a complex of examinations with the control of blood tests and other biomaterials..

“As a result of the study, we were able to exclude the relationship between chronic fatigue in people with post-COVID syndrome with muscle weakness, malfunction of the pulmonary and cardiac systems.. At the same time, we found that a decrease in the level of activity of certain areas of the cerebral cortex and disturbances in the functioning of the peripheral nervous system are analogous to the condition in people with chronic fatigue syndrome (not associated with COVID-19). As a result of these failures, people noted an increase in heart rate, a slight decrease in the oxygen content in the blood, as well as changes in the nature of the electrical conductivity of the skin.. Most often, such changes are observed when the tone of the vagus nerve is disturbed, ”the publication reports..

In the future, scientists plan to conduct scientific work to establish the common nature between chronic fatigue syndrome and neurophysiological changes caused by the new coronavirus, which will accelerate the development of drugs that help avoid the development of these conditions..
