How does COVID affect the brain? Two neuroscientists explain

Scientists are becoming more and more concerned with the emergence of a syndrome termed “long COVID”, where a significant percentage of sufferers of COVID-19 experience long-lasting symptoms. Studies suggest symptoms remain for approximately 5-24% of confirmed COVID cases, at least three to four months after infection. The risk of long COVID is no longer thought to be directly linked with either age or the initial severity of the COVID illness. So younger people, and people with initially mild COVID, can still develop long-COVID symptoms. Some long-COVID symptoms begin quickly and persist, whereas others appear well after the initial infection has passed. Symptoms include extreme fatigue and ongoing breathing complications. What particularly concerns us as neuroscientists is that many long COVID sufferers report difficulties with attention and planning — known as “brain fog”. So how does COVID affect the brain? Here’s what we know so far. How does the virus get to our brains?
