Long COVID study indicates “something concerning is happening”

0 2 years ago

Two new studies are reporting on an ongoing long COVID research project investigating the persistent effects of COVID-19 on cognition in the months after acute disease. The University of Cambridge-led research found many long COVID patients are experiencing significant and measurable memory or concentration impairments even after mild illness.

“Long COVID has received very little attention politically or medically,” said Lucy Cheke, senior author on the new studies. “It urgently needs to be taken more seriously, and cognitive issues are an important part of this. When politicians talk about ‘Living with COVID’ – that is, unmitigated infection, this is something they ignore.”

The new findings come from an ongoing project called The COVID and Cognition Study (COVCOG). The study recruited nearly 200 COVID-19 patients across late 2020/early 2021 and around the same amount of demographically matched uninfected controls. The goal was to “map the terrain” of cognition in post-acute COVID-19.

Around two-thirds of the COVID-19 cohort experienced symptoms of long COVID, defined as a symptom lasting longer than 12 weeks beyond initial date of diagnosis. Among those experiencing long COVID the new research found 78 percent had difficulty concentrating, 69 percent suffered brain fog, 68 percent reported forgetfulness and around 40 percent displayed a condition known as semantic disfluency (saying or typing the wrong word).
