  • Bringing in a medical perspective since there is a lot of subtle misunderstanding in the comments section:

    The source study is not referring to “brain bleeding” or “mini strokes” as a cause of long COVID—the results point more towards a breakdown of the integrity of the blood brain barrier and maybe micro vascular ischemia.

    You can essentially think of your central nervous system (brain and spinal cord) as being surrounded by a very selective security system called the Blood Brain Barrier (BBB). The BBB exists to prevent certain chemicals and cell signaling molecules from entering the central nervous system and messing things up. Neurons and many of the cells that support neurons do not regenerate and tolerate stress as well as other parts of the body, which is why the BBB is so important. Through the various assays the primary authors used it seems like in the setting of long COVID there is a breakdown of the BBB—it starts letting things in and out that it shouldn’t be. This leads to inflammation and damage in the brain which likely results in immediate decreased processing ability and also long-term damage (which further leads to decreased processing ability). One of the components which “leaks” in this setting of BBB breakdown are components of the coagulation cascade (the things that make blood clot) which may potentiate small areas of clotting and decreased blood flow (a thing we called micro vascular ischemia—like an ischemic stroke but in very small capillaries). This entire mechanism is similar to (but very different in nuance) “leaky gut syndrome,” where the gut endothelium starts to break down and cause inflammation. I put that out there since leaky gut is gaining more popular understanding these days and may be more familiar for some folks.

    As of now there is no available treatment that restores the endothelial integrity of the BBB. Off of the top of my head this study may suggest that more treatments to modulate the inflammsome (roughly—the amount of inflammation in your body) could be beneficial—which sort of tracks since there is some scattered evidence that high dose Omega-3’s help long COVID.









  • Yeah it was confusing and I had to read the source article a couple of times. If I’m recalling correctly I think the mouse model they’re referring to used gene splicing to reverse aging in-vivo—which to my understanding is a hell of a lot riskier and invasive than a molecular/biochemical based technique as described by the primary researchers (but only done in vitro). I would’ve been impressed if they used a biochemical technique in vivo because that would mean they had solved an issue of drug delivery, which is the thing that’ll halt the progress of this stuff becoming mainstream.






  • From the outside many people would consider me extremely successful, but I have found that my life feels like it has the most meaning and my well-being is the highest when I focus on my family and simple things. We have a society that’s quite literally sick with the idea of “chasing the grind.” I think working to better society is a virtue—but success in it may not necessarily bring you happiness.

    I highly recommend the book “Four Thousand Weeks.” Speaks to some of this.
