The coronavirus affects the brain quickly. First, the coronavirus affects not only the lungs, alas, but also the brain. Now more and more European studies show that patients can significantly damage the brain. And in inpatients, we even observe a state of delirium and psychomotor agitation, despite the fact that these are people who have never consumed alcohol. This is a reaction to the coronavirus and, of course, to a lack of oxygen.
Secondly, not only coronavirus can affect the brain, but also oxygen deficiency, because when a person has nothing to breathe, his lungs do not work well, his brain experiences hypoxia, that is, a lack of oxygen. And the consequences of this in patients persist for a long time. In principle, such consequences may persist for up to 6-7 months.
And the third factor is that people are scared. To be sick with an infectious disease from which you can die, to be sick with an infectious disease due to which they end up in intensive care, to be sick with an infectious disease from which several hundred thousand people in the world have already died, we are already talking about even a million. This is a normal reaction of a person who is sick or has not even got sick yet; it is fear. And people react to fear in different ways. And if a person, in principle, in life was anxious, suspicious, distrustful, then simply on the basis of this fear, anxiety disorder, and various other behavioral disorders may develop.
Covid-19 enters the brain?
Scientists from Germany conducted a large postmortem study of nerve tissues, taking samples from several areas of the brain and mucus from the nasopharynx from 33 deceased patients with COVID-19 aged 30 to 98 years. Some of them during illness noted confusion, intracranial hemorrhage, headaches, changes in behavior, acute cerebral ischemia.
The coronavirus can affect the nervous system in different ways, and this is not only about the loss of taste and smell. Several cases of encephalitis (inflammation of the brain), as well as Guillain-Barré syndrome, have already been described: the patient’s immune system begins to attack its nerve cells, which leads to muscle weakness and, in severe cases, to paralysis. Doctors from the United States are concerned about reports that in New York alone, five cases of major strokes were recorded in coronavirus patients in two weeks. It should be noted that this pathology was observed in relatively young people (up to 50 years old). There were no other, pronounced symptoms of COVID-19.
British neurologists have published shocking data in the Brain magazine that the coronavirus can cause serious brain damage, even in patients with mild symptoms of COVID-19 or in those who have already recovered.
Neurologists at University College London have diagnosed acute disseminated encephalomyelitis in more than 40 UK patients with COVID-19. This inflammatory disease leads to degenerative destruction of the central nervous system, which affects the so-called myelin sheath of nerve cells in the brain and spinal cord.
The incubation period of the disease can vary from:
- The main symptom of coronavirus ARVI is profuse rhinitis. The discharge from the nasal passages is profuse, fluid, non-viscous, and non-purulent.
- Febrile symptoms are moderately expressed or completely absent.
- The duration of an acute respiratory viral infection is about seven days.
- In children, the disease is often complicated by bronchitis and pneumonia due to the addition of a secondary bacterial flora.
- There may also be complaints of weakness, lethargy, dizziness, headaches, pain when swallowing, etc.
- Gastrointestinal symptoms rarely last more than two to three days.
- With the transition of the disease to a severe form, the appearance of pronounced febrile and intoxication symptoms is noted (severe weakness, chills, lethargy, vomiting and nausea, pain in muscles and joints).
- With the development of a severe acute respiratory syndrome, there is an acute onset of the disease, severe febrile, and intoxication symptoms.
The body temperature on the first day of the disease rises over 39 degrees, chills, headaches, weakness, muscle, and joint pain are noted. So be careful with your health, now you know how the coronavirus affects the brain and what to do in such cases.
