Long COVID linked to lower brain oxygen levels, cognitive problems and psychiatric symptoms

Posted on

Study is first to show link between long COVID and oxygenation changes in the brain.

Long COVID is associated with reduced brain oxygen levels, worse performance on cognitive tests and increased psychiatric symptoms such as depression and anxiety, according to new research studying the impacts of the disease.

Researchers from the University of Waterloo combined the results of two new parallel studies: a laboratory study involving cognitive testing and imaging of oxygen levels in the brain, and a national population survey of Canadians in 2021 and 2022.
