According to an article published in the Journal of Neurological Sciences written by Tissa Wijeratne and Sheila Crewther entitled “Post-COVID 19 Neurological Syndrome (PCNS); a novel syndrome with challenges for the global neurology community”, “Recent publications highlight the emerging evidence of a new syndrome–Post Covid-19 Neurological Syndrome (PCNS)”. As mentioned in part II of this article series, the SARS-CoV-2 virus affects more than just the respiratory system. For starters, the presence of the virus initiates an immunological response, which changes the blood and can affect the brain, causing neurological and psychiatric symptoms. Professor Sheila Crewther notes that PCNS is basically the brain responding to the body’s immunological response triggered by the virus.
