  • 65 Million People Have Long COVID

    A meta study found that 65 million people around the world have Long COVID. The chances of developing long COVID is 10-30% of non-hospitalized cases, 50-70% of hospitalized cases, and 10-12% of vaccinated cases. A significant number of people with long COVID are unable to return to work which contributes to labor shortages.

  • IQ Loss from COVID-19 Infection

    A study of over 100,000 people in England found that found that cognitive deficits from COVID-19 infection (memory, reasoning and executive function) were similar between those whose symptoms resolved in less than 4 weeks and 12 weeks but were larger in those who had unresolved persistent symptoms (long COVID).

  • Cognitive Slowing in People Diagnosed With Long Covid

    A study of 270 patients diagnosed with Long COVID found that 53% of patients had response times that were 2 standard deviations slower than the control mean after controlling for age-related decline and comorbidities. Cognitive slowing was also correlated with poor performance in sustained attention.
