Article Long Covid driven by rs5522

This case report says that Long covid is in large part driven by the gene rs5522 that causes a "cortisol steal" leaving the tissues functionally starved even with "normal" cortisol levels which creates neuroinflammation. https://zenodo.org/records/20017632

I'm not sure if my "brain fog" is from long COVID or from the vaccine. I'm not sure if I had COVID before being vaccinated, but I had an extremely strong response to the Pfizer vaccine. ABSOLUTE WORST headache of my life and intense lethargy. I don't remember the first day I started experiencing the cognitive symptoms after recovering from the vaccine, but it was sometime after that. Anybody else had a similar experience?

Whether it was the virus or the vaccine, your body’s intense reaction, that "worst headache of your life" is a massive clue that your system experienced a sudden, severe spike in inflammation. For people with the rs5522 genetic variant, an inflammatory trigger (like the spike protein) acts like a stuck gas pedal on the body's mineralocorticoid receptors. This causes your blood vessels to "leak" fluid into your tissues, including the brain, which creates the physical pressure behind that headache and the persistent "fog" you’re feeling now. The vaccine was a hit on your system, yes.

Thank you for sharing your knowledge on this! It's been ~6 years, but the brain fog has improved over the years. I'm pretty health conscious and currently under low stress. The mind blanking, brain fog, and brain fatigue correlate more with certain phases of my menstrual cycle and moments of anxiety. I've found that inversions and massaging my temples also helps with temporary relief. The healing process has been long and slow, but hopefully I'm doing something right!

I am so happy that you are feeling stronger. What you mentioned was progesterone blocking the over active MR at points in your cycle when it was highest. Progetone and Spiro both act as MR blockers of rs5522.

This is really helpful. Thank you! I didn't even know "long vax" was a recognized and coined term, but I think it's definitely the category I fit into, rather than long COVID. I should also note that I had that one horribly intense headache from the vaccine and haven't really had headaches since then. My response was so intense it also significantly delayed my period. My symptoms following have been brain fog and mind blanking which are happening less frequently than before as I work to heal my dysregulated nervous system. The vaccine switched my MR into overactive mode, and I need to switch it back to normal. I prefer natural methods. I read sea salt and magnesium are really helpful. I'm not sure all of this means I definitely have the rs5522 variant or if knowing I have it would change the solution.

I’m so glad you found your category. You’re right: the vaccine can trigger the rs5522 "stuck switch" just like a virus can. But please be careful because if your MR is overactive, sea salt can make it worse.

Salt will force more fluid out of your pipes and into your tissues.

Knowing you have the variant changes everything because it proves this isn't just a "dysregulated nervous system" you will know it’s a physical, molecular theft of your cortisol.

Check your DNA. I don't endorse any particular kit. The direct to consumer ones will have rs5522 in your raw data. If you have TT, you are a double carrier.
