I hope so.
But I have my doubts.
I know that there was a presentation given by Neil McGregor (a biochemist who has been doing me/cfs research since the 90s) in which he said that pwme/cfs were so very different from controls genetically that he thought that they had never in truth been well (in the sense that the controls were well).
People like Jen Brea and Julie Rehmeyer seem to have had clear mechanical CNS problems that perpetuated their ME/CFS and perhaps made them susceptible to ME/CFS in the first place. Which would also mean that they too had never truly been well in the sense that the controls are well.
Or might, I understand that while teathered cord is usually something that happens at week 10-12 of gestation it is also something that can happen later in life as a result of a traumatic injury such as a car crash. So if teathered cord sets up a subgroup up for ME/CFS, that subgroup could contain people who once were well and people who never were truly well. And one can imagine that they might get fully well after the surgery.
But only if the only difference between this subgroup and controls was teathered cord. Tis subset may for all I know have some of the genetic differences that McGregor spoke of.
I know that there are people who seem to have recovered from ME/CFS - I have two in my family. But I am not aware of any research that has compared them to healthy controls. I think I heard Ron Davis say something about the need to study these people to see if they were in fact recovered (i.e. as healthy as controls) or just better than they had been/ well enough to get by.
The group of women that Osamu Hotta studied would seem to be a useful cohort to study. They recovered from something that seemed to meet our definition, but recovery for that study was defined as having returned to work or school. They could still be pretty ill and meet that definition of recovery.
This sort of evidence makes me suspect that we may have all been people who are damaged in some way that made ME/CFS possible, and that a return to health - if possible might be a return to a sort of ill-health rather than the health enjoyed by controls.
