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.
That’s exactly it, long COVID is multiple problems in many damaged tissues. We’ve found a new damaged location, it doesn’t diminish the impact of everywhere else though like this article headline claims.
But that’s not how research works… research papers will often assess one very specific area… there’s no point in talking about all of the other ailments that are possible with Covid, because the research paper was exploring brain injury biomarkers ?
Eh, he’s not commenting on the research though. He’s commenting on the article. The headline says “Long COVID seems to be brain injury…”, but we know that can’t be the whole story. If the journalist were doing a better job, it should have said “Long COVID likely involves a brain injury…”. They might have even asked the researchers how the brain injury theory could account for diminished lung capacity - but they didn’t.
