Cognitive impairments after COVID-19 may last for years: new study data.

A new study from researchers at Mount Sinai Health System has shown that cognitive impairments caused by COVID-19 can persist in patients for an extended period. While some brain functions may improve over time, others may remain damaged for several years after the illness.

According to inkorr.com: According to a recent study, the recovery of cognitive functions after having had COVID-19 is a more prolonged process than previously expected. The study involved 1553 adults who had contracted the coronavirus. Over three and a half years, participants underwent specialized tests assessing various aspects of cognitive functions. Researchers found that memory and verbal learning recover best, while processing speed remains reduced in many patients even years after the illness.

Main findings of the study

• Memory: The best recovery of verbal learning and memory was noted, returning to normal levels in most participants.
• Processing speed: Poor recovery of information processing speed and cognitive flexibility, which remain below average even 42 months after the illness.
• Impact on recovery: The only factor influencing recovery speed is body mass index. People with normal weight recover better. Age, sex, severity of illness, and vaccination do not affect recovery speed.

These results highlight the importance of understanding the duration of cognitive impairments following COVID-19. Medical professionals should consider this issue when developing rehabilitation and support programs for patients. Brain fog occurring after the coronavirus may linger long after recovery, and this issue should be taken into account during further treatment.
