Covid linked to longer-term elevated risk of brain fog and dementia

Study finds that unlike anxiety and depression, conditions including brain fog, dementia and psychosis, are still more likely two years on

Millions of people who have had Covid-19 still face a higher risk of neurological and psychiatric conditions, including brain fog, dementia and psychosis, two years after their illness, compared with those who have had other respiratory infections, according to the single largest study of its kind.

They also face an increased risk of anxiety and depression, the research suggests, but this subsides within two months of having Covid-19. Over two years the risk is no more likely than after other respiratory infections. The findings are published in the Lancet Psychiatry journal.
