I never understood the ME/CFS term. Which disease has two different names? Is it because they equate the two? Is it because they can't make up their minds which One to pick? Is it a multiple choice? It's like saying this subject of naming the disease is too controversial, so we leave it up to choice. Is the disease a hybrid? I think that The CCC used the name ME/CFS because at that time, they did not feel that ME will be accepted. When the time came for the ICC, they felt that now the timing was right for ME to be accepted.
