hopefully we will get somewhere with these studies. The lack of solid research on a disease that affects millions (likely a good percentage undiagnosed) is really tough for patients - and myself really, as I've found i likely suffer from this. Finding out about autonomic dysfunction and small fiber neuropathy as I researched my own fatigue and finding out I likely have this has been very challenging.
It's probably more profitable to treat symptoms.
Hard to treat symptoms with immunological conditions. I mean, there are vitamins and supplements, but noone is gonna generally hand out economy-sized bottles of controlled substances for exhaustion, etc.
These sorts of conditions are systemic, and the causes and ways of dealing with the accompanying syndromes are probably always going to be different from individual to individual (well, likely the exact physiological causes anyway).
