Brain fog has been reported by many people across the world after recovering from a COVID infection.
While brain fog is considered one of the long-term covid symptoms, in many cases it also occurs in people who do not have long-covid symptoms.
According to a report by the Daily Mail based on research findings from Oxford University, people who had mild COVID infection but did not report long-term COVID symptoms still had poor attention and memory for six to nine months. .
The study, conducted by Oxford’s Department of Experimental Psychology and the Nuffield Department of Clinical Neurosciences, performed cognitive tests in a group of participants with a focus on maintaining attention, memory, planning and semantic reasoning. The study found, “While they did well in short-term working memory and planning compared to the control group, participants performed significantly worse in their recall of past events and in their ability to maintain attention over time.” Fortunately, most people’s memory and attention return to normal after six to nine months, it also said.
Several other studies have also confirmed difficulties in maintaining attention in post-COVID patients.
