Chart by The Economist shows levels of “brain fog” at different levels of Covid-19 seriousness.
Covid-19 is a new disease that is not fully understood, but new research by American and British scientists shows it causes problems with memory and concentration, often known as “brain fog,” even in mild cases.
The researchers teamed up with the BBC on the “Great British Intelligence Test,” an online assessment billed to the public as a way to “test your cognitive strengths.” About 80,000 people “were asked to remember lists of numbers or locations on a chessboard to test their recall,” The Economist reports. Other tests measured planning ability, verbal skills, problem-solving and the ability to manipulate information. “Questions about the virus, as well as about demographic factors such as age, ethnicity and socioeconomic status, were asked only after the test had ended.”
