How the Covid attacks the brain

DECRYPTION – European researchers believe they have uncovered the mechanism that would explain certain neurological disorders.
At first, Covid was primarily considered a lung disease. The most severely affected patients did indeed suffer from acute respiratory syndrome, as seen in influenza.

But anosmia and cognitive “fog” are also very common in those with mild forms of the disease. So everything seems to indicate that somehow Sars-CoV-2 does much more than attack our lungs.

In Nature Neuroscience, a team brought together within a European consortium recently proposed a microvascular pathway: the virus would destroy cells lining the blood vessels of the brain, disrupting its blood supply. The mechanism in
