Neurological disorders such as stroke and dementia were less common, the researchers said, but were still significant, especially in those admitted to intensive care..
“These are real data from a large number of patients. They confirm the high rate of psychiatric diagnoses after Covid-19 and show that serious disorders affecting the nervous system (such as stroke and dementia) also occur, “lead author Paul Harrison, a professor at Oxford University, said in a statement.
“Although the individual risks for most disorders are small, the impact on the entire population can be significant for health and social systems because of the scale of the pandemic and because many of these conditions are chronic,” he added.
Covid-19 causes a higher neurological risk
The study also found that patients with Covid-19 had a 44 percent increased risk of neurological and psychiatric illnesses compared to people recovering from the flu, and a 16 percent higher risk than those with respiratory tract infections.
“Our results show that brain diseases and psychiatric disorders are more common after Covid-19 than after flu or other respiratory infections, even when patients match other risk factors. Now we need to see what happens after six months,” Max Taquet said. , a psychiatrist from the British University of Oxford, who co-led the work.
