Researchers have investigated why some people experience long-term symptoms after a COVID-19 infection. It was thought that inflammation in the brain might be the cause. However, a new study using brain scans shows that there is no evidence of widespread inflammation in the brain.
What was noticeable, however, was that people with the most severe long-term symptoms had increased activity in parts of the brain associated with mood and emotions. This may explain why these symptoms often go hand in hand with feelings of depression and anxiety.
These new findings are important, because they help to better understand what happens in long-term symptoms after COVID-19. This may ultimately lead to better treatments aimed at reducing emotional and mood-related symptoms.
For people who are concerned about their health after an infection, it is reassuring to know that no lasting inflammation is found in the brain. It also underlines the importance of paying attention to mental health as we age.
