Yahoo Autos COVID raises risk of long-term brain injury, large U.S. study finds

CHICAGO (Reuters) - People who had COVID-19 are at higher risk for a host of brain injuries a year later compared with people who were never infected by the coronavirus, a finding that could affect millions of Americans, U.S. researchers reported on Thursday.
The year-long study, published in Nature Medicine, assessed brain health across 44 different disorders using medical records without patient identifiers from millions of U.S. veterans.
Brain and other neurological disorders occurred in 7% 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 team 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.
Al-Aly and colleagues at Washington University School of Medicine and the Veterans Affairs St. Louis Health Care System studied medical records from 154,000 U.S. veterans who had tested positive for COVID from March 1, 2020 to Jan. 15, 2021.
