“At first, we thought that the brain was the organ that was saved the most than the coronavirus, because we had all looked at the lungs and it is still the one that suffers the most. When we talk about brain or neurological symptoms, these can be caused by three mechanisms. One is when the virus enters brain tissue directly, when it begins to damage nerve cells, called encephalitis. Fortunately, this event is very severe, but also very rare, “said the neurologist and rector of the Sofia University of Medicine, Acad. Lachezar Traikov in” This Saturday “on bTV.
“There is a barrier between the blood and the brain. It is a special body. Nature has thought about it and saved it. Not everything in the blood takes it to the brain. For now, this barrier stops the virus in most of people, “Acad explained. Traikov.
“The other mechanism is the so-called vascular mechanism: the so-called blockages, the formation of blood clots and strokes.” This is a mechanism that is also rare for the brain, “said the neurologist.
“Very often, this is the mechanism of taking oxygen from the blood. This is the most common consequence of infection. The brain feeds on oxygen and glucose. If oxygen drops, this is our marker. It is difficult to concentrate, it is difficult to go from one activity to another, “explained Acad. Traikov.
In this case, again, people with comorbidities such as being overweight or smokers are particularly at risk, the neurologist said.
