A study has revealed that people who have had Covid-19 infection are at a higher risk of a long-term brain injury, a year later compared to the people who have never been infected with the virus.
The year-long study, published in Nature Medicine, assessed brain health across 44 different disorders using medical records without patient identifiers from millions of US veterans.
Brain and other neurological disorders occurred in 7 per cent more of those who had been infected with Covid compared with a similar group of veterans who had never been infected.
That translates into roughly 6.6 million Americans who had brain impairments linked with their Covid infections, the study said. "The results show the devastating long-term effects of Covid-19," senior author Dr Ziyad Al-Aly of Washington University School of Medicine said in a statement.
