Hi Mark, Thanks for youir long post. I remember when the name change was done and it was done to strengthen the name against criticism from the psychological school. Medical names have to be accurate descriptions of the condition and myelitis could not be defended as there was no hard evidence to prove inflammation. Dr Shepherd was one of the people who fought against a move from the psychologists at the time to change the name completely to chronic fatigue syndrome as it was said that that was the only name that could be medically defended given the absence of proven medical pathology. Otherwise we could have ended up as pure "chronic fatigue" as in America. I hope this explanation helps. I do not support the psychologists myself.
