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.
As someone with long COVID, I can vouch the debilitating mental effects. I was teaching math to 4th through 8th grade students when I got it. I can remember standing in a classroom talking about a lesson and just having my mind go blank in mid sentence. I couldn't function. Not knowing what I was talking about or even where I was. Thankfully the students where very understanding and someone would finish my point I was making. I still suffer from it yet today, nearly 2 years later.
I have respiratory issues despite every CT scan showing nothing more than a couple of small pneumonia scars form long ago. I should be able to breathe just fine with no reduction of lung capacity. It stems from a lack coordination with my diaphragm - It runs backwards when I exert myself causing shortness of breath. Another sign of probable brain injury. And despite using a therapy tool to try and fix the issue, at best it just helps a little.
The upshot is I have pretty much stopped doing a lot of things I used to do because of the difficulties breathing and I spend a lot more time away from people due to an unreasonable fear of COVID.
It has caused me to retire earlier than I wanted to. And my life has greatly changed - and not for the better either.
Sorry you're going through all of that. There obviously aren't any long term studies on it yet, but hopefully things will improve more and more over time.
According to my Pulmonolgist - Nope. Her observations of all her patients over the years is that if you don't get over it in about a year, you don't get better. And she has been seeing more COVID patients than her "normal" patients for several years now. Long term care is going to be a real problem for society going forward.
