Scientists are astounded by the effect of Covid-19 on the brain


During a study on the effect of the Corona virus on the brain, a group of scientists discovered signs of damage resulting from thinning and leakage of blood vessels.

But these scientists, from the US National Institute of Health, did not see any signs of SARS-CoV-2 in the tissue samples, indicating that the damage was not caused by a direct viral attack on the brain.

The study, published by the New England Journal of Medicine, said that scientists have found that the brain of someone infected with the Coronavirus may be vulnerable to damage to small blood vessels.

The study indicated that the reason for this may lie in an inflammatory reaction of the body to the entry of the virus.

The scientists conducted an in-depth study of brain tissue samples from 19 patients who died after being infected with the Coronavirus, from March to July 2020. Their ages ranged from 5 to 73 years. Many of them had one or more risk factors: diabetes, obesity, cardiovascular disease, and others. Brain scans revealed several bright spots in the brain that indicate inflammation, as well as some dark spots that indicate bleeding.
