Why do some people develop stressful long-term consequences, called Long Covid, after a corona infection? There is still no certain answer to this question. A new study is now focusing on two biomarkers in the blood that are associated, among other things, with so-called brain fog.
On May 5, the pandemic was officially over: The World Health Organization declared the global health emergency caused by the new coronavirus to be over. But there are many people who still have more than just memories of Sars-CoV-2 and Covid-19. In some cases, they continue to suffer from symptoms caused by an infection with the virus for months after being infected. A study recently confirmed that such symptoms can persist two years later – that’s how long the observation period lasted. If you then look at the catalog of the most frequently mentioned symptoms, there are a striking number of “neuropsychiatric” findings in the top group: impairments in cognitive performance, for example, and also the infamous “brain fog”, the impression that the brain is as if it were under a drug Mist billows through.
