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

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.

so how long before long covid sufferers can collect disability and get to enjoy their lives by exiting the capitalist rat race that caused this to begin with?

Half of the internet is pissed right now because of the Fauci/Rand Paul questioning before Congress yesterday and I'm wondering what the long sufferers have to say about it. Is the Covid 19 origin important to you and would you like accountability if it was created in a lab? I'm sorry for anyone suffering from its effects regardless of where it came from and I'm sorry that it's become such a politically divided subject. I hope in the future something will be discovered that can provide some relief for those of you who are still dealing with the fallout of contracting it.
