The exact nature of long COVID is still coming to light, but we just got some of the best evidence yet that this debilitating condition stems from a brain injury.

Using high-resolution scanners, researchers at the Universities of Cambridge and Oxford have shown microscopic, structural abnormalities in the brainstems of those recovering from COVID-19.

Signs of brain inflammation were present up to 18 months after first contracting the SARS-CoV-2 virus.

"We show that the brainstem is a site of vulnerability to long-term effects of COVID-19, with persistent changes evident in the months after hospitalization," the authors of the study conclude.

Finally we agree. Like everything else in the above list, this is a theory that was claimed to be false that later turns out to be correct.

The lab leak conspiracy hypothesis was initally denied by the lead investigator, Peter Daszak, and now turns out to be highly probable (almost certain given the lack of zoonotic spillover evidence).
