Do you mean from CCI as the cause, point of view, causing all these other problems?
I mean any neuro abnormality or "glitch", including but not limited to CCI/AAI, Chiari malformation.... Weirdly, the neuro root cause has been on my mind this year (as you know, I've been experimenting w the higher fat diet developed/researched/published that alleviates M.S. severity...). I hadn't heard about CCI/AAI, etc., and I don't know if that's an issue for me. The neuro track remedies that I've devised for myself have been helpful, though (when I can afford them!). Higher fat diet, cranial sacral work, fish oil & astaxanthin all help w neuro symptoms (plus non-corn vitamin C for MCAS, magnesium/malic acid for muscles, and occasional betaine, low-carb & IF for digestion).
I hope there is more research in this area (ie framing CFS as a Neuro-Immune disease, like M.S.). The stuff I've been doing is incrementally helpful, but the science community needs to step up if I'm ever going to truly recover.
one last comment re neuro track: I saw an allergist who did extensive testing and NONE of my tests came back positive. Which was puzzling b/c I'm so reactive to dust, pollen, pollution PM.. (neither she nor I knew about MCAS so unfortunately, no MCAS testing). I told her that pollution particulate matter is a huge trigger for me, and a very bad experience w high PM (like Cali forest fires) can send my health into a tailspin for months.... She said it's not an allergic reaction (IGE), but the PM is stimulating my nervous system.... She couldn't help me and referred me to another doc (because, of course!) However, I think she was on the right track. I would take it a step further and say the PM triggers my nervous system, and that stimulates a MCAS reaction.
