There is no authoritative literature or clinical data confirming that neocollins cause brain atrophy. This is despite the fact that some studies have shown that in some trials of patients with neocoronavirus pneumonia, neocoronavirus has caused considerable effects on the brain, including cerebral atrophy. However, the results of the trials are not directly applicable to the clinic and do not mean that this conclusion is correct. To date, there is no authoritative literature or clinical case data to confirm the authority of this view. The current understanding of the sequelae of New Crown exists mainly in the respiratory system, digestive system, etc. As to whether brain atrophy will occur, further data and experiments are needed. The infectiousness and pathogenicity of the new crown virus is still unclear, therefore, we can not ignore this virus, we should wash our hands diligently, wear a good mask, do not go to crowded places, and do a good job of vaccination. Tip: The terms “new coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
