✔ A new study might explain why some people suffer from “brain fog” after contracting COVID-19. ✔ It appears their brains may be different than those who don't have that side effect. ✔ Researchers at Trinity College in Ireland put nearly three dozen patients through a brain MRI. The MRI showed that the long COVID patients had more of what they “leakiness” in the blood-brain barrier. ✔ It is the first evidence that COVID brain fog may be connected to changes in the brain. ✔ While this study is small, it could help inform ongoing research to better understand how to diagnose and treat long COVID that impacts millions of Americans.
