    A study finds that COVID-19 is linked to a substantial drop in intelligence...

    People who have recovered from COVID-19 tend to score significantly lower on an intelligence test compared to those who have not contracted the virus, according to new research published in The Lancet journal EClinicalMedicine. The findings suggest that the SARS-CoV-2 virus that causes COVID-19 can produce substantial reductions in cognitive ability, especially among those with more severe illness.

    “By coincidence, the pandemic escalated in the United Kingdom in the middle of when I was collecting cognitive and mental health data at very large scale as part of the BBC2 Horizon collaboration the Great British Intelligence Test,” said lead researcher Adam Hampshire (@HampshireHub), an associate professor in the Computational, Cognitive and Clinical Neuroimaging Laboratory at Imperial College London.

    “The test comprised a set of tasks designed to measure different dimensions of cognitive ability that had been designed for application in both citizen science and clinical research. A number of my colleagues contacted me in parallel to point out that this provided an opportunity to gather important data on how the pandemic and COVID-19 illness were affecting mental health and cognition.”

    Many of the reactions to Covid 19, especially in government, have certainly lacked intelligence.

    “We need to be careful as it looks like the virus could be affecting our cognition. We do not fully understand how, why, or for how long, but we urgently need to find out. In the meantime, don’t take unnecessary risks and do get vaccinated,” Hampshire told PsyPost.

    The level of cognitive underperformance was also associated with the level of illness severity, with those who were hospitalized on a ventilator showing the greatest deficits. The observed deficit for COVID-19 patients who had been put on a ventilator

    That site reads like medical satire made up by adolescents who know a few big words and concepts and are having fun seeing how many dummies buy into it.

    It was a small group of people used that actually got COVID. Just 326, of which they had 192 people that were hospitalized. So the results were really just an indication.

    I'm curious how long after they were declared free of COVID did they test again. Was this more fatigue than long term change.

    Now run away midcan5, it's what you do best.

    If he doubted the OP-linked article all he had to do is open it and go to the original paper it links too: Cognitive deficits in people who have recovered from COVID-19:

    ...Findings

    People who had recovered from COVID-19, including those no longer reporting symptoms, exhibited significant cognitive deficits versus controls when controlling for age, gender, education level, income, racial-ethnic group, pre-existing medical disorders, tiredness, depression and anxiety. The deficits were of substantial effect size for people who had been hospitalised (N = 192), but also for non-hospitalised cases who had biological confirmation of COVID-19 infection (N = 326). Analysing markers of premorbid intelligence did not support these differences being present prior to infection. Finer grained analysis of performance across sub-tests supported the hypothesis that COVID-19 has a multi-domain impact on human cognition.

    Interpretation

    Interpretation. These results accord with reports of ‘Long Covid’ cognitive symptoms that persist into the early-chronic phase. They should act as a clarion call for further research with longitudinal and neuroimaging cohorts to plot recovery trajectories and identify the biological basis of cognitive deficits in SARS-COV-2 survivors.
    Instead he quotes Chesterton commenting about people like midcan.

    It's just anecdotal, but I have neighbor (mid-40's, otherwise healthy) who had COVID six months ago and has had significant lingering cognitive problems, to the point of not being able to even remember the names of people she's known for years. People who cite only mortality data in trying to dismiss the seriousness of this virus are ignoring its many, significant non-fatal impacts.
