Generally a pretty hyperspecific paper, but there is an important takeaway. This is the first paper I have seen to document neurovascular changes after covid.
“The morphological differences may be due to the neuroinvasion and neuroinflammation potential of SARS-CoV-2, while the vascular differences may be due to hypercoagulation and enhanced thrombosis,” Semra Tiryaki Demir, MD, FEBO, said at the virtual Euretina congress.
So what? Well, the retina is essentially an extension of the brain, and this may be an indication of how the loss of cognitive abilities documented as “covid fog” and “cognitive decline” are occurring.
Maybe a bit in the weeds, but intriguing if it pans out as a possible target for therapy. And an idication of why “natural immunity” is a really, really bad idea.
