Researchers find that people who only suffered mild infections can be plagued with life-altering and sometimes debilitating cognitive deficits.
How does COVID-19 affect the brain? A troubling picture emerges.
Hannah Davis contracted COVID-19 in March 2020, the early days of the pandemic. At the time, the New Yorker was a healthy, 32-year-old freelance data scientist and artist. But unlike many people who come down with the disease, Davis’s first sign of infection wasn’t a dry cough or fever. Her first symptom was that she couldn’t read a text message from a friend. She thought she was just tired, but the fuzziness she felt didn’t go away after a full night’s sleep.
More neurological issues followed. She developed sudden and severe headaches. Her attention span suffered. She couldn’t watch TV or play video games. She had trouble concentrating on everyday tasks like cooking. She’d leave a pot on the stove and forget about it until she smelled food burning. She failed to look both ways while crossing the street, narrowly missing traffic. She’d never had any of these issues before COVID-19.
Davis is among a large portion of COVID-19 patients—possibly as high as 30 percent, according an estimate from the National Institutes of Health—who suffer some type of neurological or psychiatric symptoms. Even more troubling is that for many of these individuals, like Davis, these cognitive issues can linger for weeks or months after the initial infection.
“The expectation was that all these people in the ICU were going to have really long protracted recovery periods,” says Walter Koroshetz, director of the National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health. “The big surprise was the people who never required hospitalization that are having persistent trouble.”
