Description
Ahmar Faseeh and co-authors published a review in 2026 on brain fog after COVID-19. Long COVID can affect many parts of the body, and trouble with thinking is one of its common signs. The team asked how often brain fog and loss of thinking skill occur, and how long they last.
The review covered forty-seven studies with more than twenty-five thousand patients. About thirty in a hundred had brain fog, and about twenty-five in a hundred had loss of thinking skill. Rates were higher in women than in men, and higher in those who had not had a vaccine. Rates rose with longer follow-up, which hints the signs can persist or show up late. The authors call for work on causes and on care that targets these signs.
