>Mild cognitive decline was noted after infection with the wild-type virus and with each variant, including B.1.1.529 (Omicron). Relative to uninfected participants, cognitive deficit (3-point loss in IQ) was seen even in participants who had had completely recovered from mild COVID-19.
>Participants with persistent symptoms had the equivalent of a 6-point loss in IQ, while those who had been admitted to an intensive care unit (ICU) experienced the equivalent of a 9-point loss in IQ.
