Immune system mediated injury rather than the virus entering and killing brain cells may explain why people experience long-term consequences associated with COVID-19 infection.
Researchers report some patients with long-COVID have lasting nerve damage that appears to be caused by infection-triggered immune dysfunction.
Many patients report symptoms of "brain fog" and confusion as a result of COVID-19 infection. Researchers report inflammatory molecules in the cerebral spinal fluid could be the cause of brain fog associated with coronavirus. Anti-inflammatory drugs, such as steriods, could help alleviate the symptoms of COVID brain.
