It has been established how exactly the coronavirus is dangerous for the brain COVID-19 causes neurocognitive changes in the brain that may turn out to be unchanged. This sad conclusion was reached by researchers from the United States.

Studies show that SARS-CoV-2 infects brain cells called astrocytes, which causes structural changes in this organ.. In particular, coronavirus contributes to neurocognitive dysfunction, especially in the long run, although the underlying mechanisms for this are still not established.. Scientists used MRI and compared brain structures in 81 volunteers who had already recovered from mild coronavirus, as well as in another 81 healthy control group participants..

How dangerous the coronavirus is for the brain In the first group, the thickness of the cerebral cortex was less than in the second, and this indicator directly depended on cognitive impairment and the severity of symptoms such as anxiety and depression. An analysis of brain samples from 26 people who died after coronavirus showed that in 5 cases severe damage to brain tissue is observed.. And their study found that brain cells, astrocytes, which support the metabolism of neurons, were the first to be affected by the coronavirus..

Scientists: eating at night is dangerous for the brain Researchers have discovered a receptor through which covid sneaks into astrocytes. After this happens, the cells show an altered level of metabolites needed to feed neurons and produce neurotransmitters.. Affected cells secrete neurotoxic molecules. The study showed exactly how the coronavirus sneaks into the brain, and on the basis of this information it is possible to develop methods of protection.
