Hi,
Autoimmune is the body destroying it's system, Autonomia is the damage caused to the Autonomic nerve system, by other causes. Neither have a cure and there are very limited treatments. With Autonomic neuropathy (ANS) there are no treatments currently known. If you are able to detox you didn't have either. I believe a plasma infusion can aid autoimmune problems but are short term fixes as you need to stop the body doing the damage to itself.
I had a friend who had to get plasma infusions every month just to survive until the next infusion.
With autonomic neuropathy it can be totally random episodes, permanent features or a mixture of both. If you are lucky enough to have Autonomic polyneuropathy as I do, then both major nerve systems, autonomic and peripheral nerves are compromised and life gets to be hell, the only cure I have discovered is death! Your life is no longer up to you, ANS takes over dictating how your body might react at any given time, from stopping the heart instantly without warning to affecting your organs and even permanently affecting your BP. You either sit and wait for ANS to take you or you get on with life as best you can trying to forget ANS exists. The best feature of ANS is everybody dies sooner or later so no surprises there, life continues until it doesn't, all you can do is fill every moment you have as best you can.
Cheers
