EYECARE: Coronavirus BRIEFING: Crisis Response Tactics Cognitive Slowing May Be a Hallmark of Long COVID By Staff Tuesday, February 6, 2024 6:09 AM Pronounced cognitive slowing distinguished people with long COVID from others, a cross-sectional study showed.On a 30-second task measuring simple reaction time, moderate-to-severe cognitive slowing was evident among long COVID patients compared with age-matched healthy individuals who had previous symptomatic SARS-CoV-2 infection and recovered, reported Sijia Zhao, PhD, at the University of Oxford in England, and co-authors in eClinicalMedicine.Long COVID patients responded to visual stimuli at about 3 standard deviations slower than healthy controls, Zhao and colleagues said. More than half (53.5%) of long COVID patients had a response speed slower than 2 standard deviations from the control mean, suggesting that slow reaction time was a common cognitive deficit.
