The current study shows brain inflammation inpeople who have recovered from acute COVID-19 but go on to have lasting neurological problems -- even though their initial infection wasn't severe, he said. Most of them had additional cognitive issues associated with long COVID, including problems with memory and concentration, also known as "brain fog."
Those are parts of the brain associated with the ability to experience enjoyment, energy and motivation levels, cognitive processing and speed of movement. Dr. Angela Cheung, co-lead of a national long COVID research network and senior physician-scientist at the University Health Network in Toronto, said the study confirms what long COVID researchers have suspected for some time.
