Those who have been ill with COVID-19 after a while begin to complain of “fog in the head”
The insidiousness of the coronavirus turned out to be stronger and scarier than its contagiousness and even lethality. More and more people are reporting strange and disturbing symptoms that appear only months after a seemingly successful recovery. As researchers from the University of California at San Francisco found out, the impact of COVID-19, figuratively speaking, “drives the body’s immune system crazy” and generates dangerous pathologies.
The study was conducted on the basis of complaints from patients who reported that 1-2 months after recovery from covid, they had some kind of “fog in their head” — cognitive abilities dropped sharply. A thorough analysis revealed abnormal biomarkers in their cerebrospinal fluid — for example, unusual volumes of antibodies. And also special proteins that indicate the presence of neuroinflammations – the immune system of those who have been ill runs amok for no reason.
The preliminary conclusion says that the unprepared immune system misses the first blow of the coronavirus, and then begins to feverishly resist it, exceeding the permissible effects on the body by a multiple. For example, it triggers a permanent immune activation mode, which generates a post-infectious autoimmune response. All this happens belatedly, when the virus is often no longer in the body, and therefore the whole blow is taken by healthy body systems. Probably, it is here that the answers to questions about those strange sensations experienced by those who have had covid are found.
