Science: How does the coronavirus affect the brain?

According to an article published in The New York Times, it is not just the damage that the virus can cause to the lungs and other organs related to the kidneys, liver or blood vessels. In a recent scientific study, it was reported that the pathogen can enter brain cells and cause symptoms such as delirium and confusion.

How does it happen? A new study warns that, in some cases, the coronavirus invades brain cells to make copies of itself and takes in all the oxygen within reach, depriving surrounding cells and tissues. It is not possible to determine how often this happens, but certain genetic predispositions or a high viral load are thought to make it possible.

According to the article, the virus infects a cell through a protein on its surface called ACE2, which is present throughout the body but mostly in the lungs, which would explain why it isone of the targets of the virus. The brain is known to have very little ACE2 receptros, but it is now also known that the virus can enter cells using this mode of entry. Is the damage reversible? No answer found yet.
