Story summary

A study in *Brain, Behavior, & Immunity – Health* suggests cognitive recovery from post-COVID "brain fog" may take years.
Researchers monitored 1,553 participants over 3.5 years, noting improvements in verbal learning and memory, but some deficits remained.
Lower body mass index was linked to better recovery; COVID-19 severity did not influence outcomes.
Further research is required to identify effective interventions and biological markers for recovery.
