Some form of brain injury could be behind the symptoms reported by those with long COVID, according to a new study, and adapting tests and treatments to match could aid progress in tackling the condition.

Analyzing 203 patients hospitalized with COVID-19 or its associated symptoms, and comparing the results with 60 people without the infection, researchers noticed elevated levels of four brain injury biomarkers – key signs of biological change – in those infected with COVID-19.

What’s more, two of those signs of brain injury persisted into the recovery phase, suggesting that they continue even after the COVID-19 infection has gone. Levels of these two biomarkers were even higher for people who also experienced neurological complications with COVID-19.

    Attributing long COVID to a brain injury is just wrong. Long COVID is the result of multiple damaged organs, including lungs, peripheral and central nervous systems, the heart, etc.

    What’s worse, this is entirely correlative. Bio markers are correlative indicators of disease, and while sometimes there is a causal relationship that is something that must be tested and proven before you can make the claim that it’s the source of the issue.

    If long COVID correlates with brain injuries and certain elevated bio markers, it could very well be an artifact of reaching a high viral burden during peak infection. The immune system couldn’t prevent damage to the brain during a period of time, for example. It makes sense that if the immune system couldn’t prevent damage during this time, that the lungs were getting ravaged because the immune system couldn’t mount an effective defense in the tissue.

    There are so many possibilities that are glossed over by a simplified headline like this and worse, it will stick in people’s minds that have no idea how complex the situation really is.
