It is well established that Covid-19 presents itself primarily as a respiratory virus, but it can affect the entire body, including the nervous system. In a new paper, experts highlight how Covid-19 affects the brain.
The research paper, published in Science, focuses on the importance of research into the impact of Covid-19 on the nervous system. It paves the way for understanding the underlying causes of long Covid and possible ways to treat the condition.
Researchers note that neurological symptoms reported with acute Covid-19 include loss of taste and smell, headaches, stroke, delirium, and brain inflammation. They note that evidence does not show extensive brain infection caused by Covid-19. However, the neurological impact may be caused by immune activation, neuroinflammation and damage to brain blood vessels.
