Description
Anna Szente and co-authors scanned the brains of people who had recovered from mild COVID-19, in a study published in 2025. Long-term effects of the virus show most after severe illness, yet milder cases can leave fatigue and thinking complaints. The team enrolled forty recovered subjects and thirty-six healthy controls. Brain scans at rest were paired with mental health questionnaires and thinking tests.
The recovered group showed no clear thinking deficits on the tests. Their resting brain networks, though, differed from controls, with some connections stronger and others weaker than normal. The authors read the mixed pattern as the brain adapting while it heals, a common response after viral infections. They note it could also mark an ongoing post-COVID process in the brain. Either way, the scans suggest mild infection can leave traces long after symptoms fade.
