In an attempt to understand the effect of the new Corona virus (Covid-19) on the bodies of the infected, scientists looked at the strange and terrifying damage it can inflict on our bodies through the autopsy of several Corona patients after their death, and the surprise was that the damage is much greater than is known.
Now, after an in-depth study of a patient’s anatomy, it revealed greater details of inflammation and damage to brain tissue on a large scale, and this may help explain the neurological symptoms that appeared in some patients, from headache, loss memory, dizziness, weakness and hallucinations up to severe attacks and strokes.
Some estimate that up to 50% of those hospitalized with Covid-19 could have neurological symptoms. “We were completely shocked … and we expected to see the damage from the lack of oxygen,” said Avendra Nath, physician and clinical director of the National Institute of Health. Instead, we saw areas of multifocal damage commonly associated with strokes and inflammatory and neurological diseases. “
NIH researchers, including Dr. Myung Hwa Lee and Nath, performed precise examinations of the brain tissue of 19 deceased patients, whose ages ranged from 5 to 73 years, and many of them had risk factors for severe coronavirus infection. , including diabetes and cardiovascular disease. Bloody.
Using a powerful magnetic resonance imaging (MRI) microscope, Li and his team identified 10 patients with brain abnormalities, and a close examination under a microscope revealed excessive density of brain samples, the microscopy of which showed a leak of fibrinogen (a protein of the blood).
Protein from the blood surrounded immune cells in the brain and other small cells, and there were also dark areas of clotting bleeding, leading to the conclusion that these patients had suffered a small brain hemorrhage, a type of damage generally associated with inflammation in the brain.
And it’s not just those who are sick enough to need intensive care, or those with pre-existing conditions, who have shown neurological symptoms of Covid-19, neurologist Benedict Michael of the University of Liverpool told Nature last September: “We have seen “A group of young adults develop strokes without traditional risk factors and patients with severe changes in mental state that have not been explained.”
