The terrible effect of coronavirus in the brain
Due to tissue tropism, coronavirus not only attacks our airways and lungs but also infects other organs and tissues of the body. The virus can infect all cells and tissues in the body that have ACE-2 receptors. This is why in addition to the lungs, the virus is found in the vascular endothelium, intestinal epithelium and kidneys.
The symptoms of coronary heart disease vary considerably from place to place.
Since the coronavirus mainly attacks the lungs, in most cases the disease begins with cough, sore throat, fever and shortness of breath. Patients lose their sense of smell when the virus infects the mucous membranes of our nose. Infection of intestinal cells leads to intestinal disorders and diarrhea.
COVID patients can also manifest the disease by showing human symptoms such as headaches, confusion, delusions or delirium. From this, doctors speculate that the coronavirus may also infect nerve cells in the brain.
A team of British scientists recently conducted a study on 43 corona patients admitted to various hospitals in London. Analyzing the clinical data of the patients and the results of laboratory tests, they found that 10 of them had encephalopathy, and they were very deranged. However, MRI and neurosurgery (CSF) tests of their brains did not reveal any abnormalities.
Of the rest, 12 had encephalitis and encephalomyelitis (ADEM). Among them, bleeding was found in the brains of 5 people and necrosis of one person. In addition, 6 people have a stroke due to blockage of blood vessels in the brain and 6 people have Gulen-Berry Syndrome - it is a type of paralysis. In addition to these, patients show a variety of other neurological symptoms
However, coronary artery disease and blood vessel abnormalities were significant. Surprisingly, the brain problems were not related to the severity of the corona. This means that many mild corona patients have also shown brain symptoms.
Brain dissection is needed to see how much the coronavirus directly infects the brain. And this is what Italian scientists do. 18 people died of coronary heart disease through autopsy. All the patients died within 2 to 9 days of being admitted to the hospital suffering from severe Nvidia. And some of them also had neurological or neurological symptoms.
After death, patients underwent RT PCR and immunostaining to detect coronavirus in the brain tissue.
A small amount of coronavirus was observed in the brain tissue of 5 out of 17 people who underwent PCR. However, immunostaining did not detect the presence of any virus in the brain tissue of any patient. No patient's brain has seen the same changes in cells or collars that occur when a virus infects a nerve cell. However, microscopic ischemia or oxygen deficiency injuries are found in the brain tissue of all patients.
From this, scientists conclude that the coronavirus may not infect the human brain directly. The small amount of virus that was found in the brain cells was probably inside the blood vessels of the brain. The coronavirus infects blood vessel cells. The study was published in the New England Journal of Medicine.
From these two studies it is clear that the coronavirus can cause serious complications in the brain. Therefore, corona patients need neurological examination in diagnosis and treatment.
