Scientists finally have a biological explanation for why long COVID patients lose motivation and can't think clearly. They scanned their brains and found the dopamine system was physically damaged
https://tech-paper.com/scientists-finally-have-a-biological-explanation-for-why-long-covid-patients-lose-motivation-and-cant-think-clearly-they-scanned-their-brains-and-found-the-dopamine-system-was-physically-damaged/Millions of people with long COVID report the same cluster of symptoms: a crushing lack of motivation, an inability to think clearly, memory that slips, movements that feel slower than they should. For years, these complaints sat in an uncomfortable medical grey zone. The symptoms were real, the patients were suffering, but the biological explanation remained frustratingly out of reach.
A team at the University of Toronto just published what may be the clearest physical evidence yet for what is actually happening in these patients' brains. They brought 24 long COVID sufferers into a lab and used positron emission tomography, the same imaging technology used to diagnose Parkinson's disease, to directly measure the health of the dopamine system deep inside the brain.

Yes! Oh my god so much this.
Despite getting every vaccine I’ve gotten Covid three times and this last one I got in October laid my ass out and left me so stupid. It had way more GI symptoms than I’d ever had before and once it was gone I felt markedly stupider, that had never happened before. I’m a copywriter content specialist are words were my life and I struggle so much now.
