What Andrew said.
Some random thoughts.
We can yell from the rafters here in US that we have ME, and main street doctors will look at us confused. Until research leads government to better word(s), we will have CFS. I don't have the energy to advocate for a name change. My doctor knows I don't have a psychological illness. She runs tests and addresses symptoms as they come up. But all of her sincere efforts are of little effect. My symptoms seem much more responsive to my pacing, avoiding stress, getting enough effective sleep, not getting another virus and not eating sugar or caffeine. She gives me synthroid, cortisol and ambien. Honestly, the only one I can see that helps is ambien. (Someone would have to kill me to get my Ambien) The other two, well, I'm not so sure. And I am even concerned the cortisol is hurting.
If this were two years ago, I could get all into advocating for a name change, to neuroendoimmune dysfunction. I just don't like ME or CFS. Both have baggage. And neuroendoimmune dysfunction is accurate and not belittling. But soon, most of us will get a new name anyway. I don't know if XAND will stick or if something else will come up. But I am confident in the WPI research. So I want to put my efforts into awareness and research. I guess getting the names right just seems like a big, big battle that would require a whole lot, and hey, it was tried before. And I just think it is futile at this time. We have lots of othr battles at this time.
Also, I don't like "fatigue" either. But, it is a medically recognize symptom for biological illnesses, such as flu, as well as psychological ones and body overuse. But just because it is associated with others, doesn't mean that doctors dismiss it. Fatigue is symptom of cancer, lupus, sleep apnea and many other biological illnesses. I think the word "exhausted" is worse. Fatigue is a medical term. Whereas, exhausted is what people say after they hiked a long like. "I'm so exhausted," is often heard after someone hiked a mountain. They don't usually say, "I am so fatigued." If you tell a doctor you are exhausted all the time, he will likely right in his notes "fatigue" because exhausted is not a symptom of illness. Now, because "fatigue" is a medical term, it has been adopted by fake conditions to give them a medical sound. One is "driver fatigue". But this is effect of healthy person driving too much. It is not an illness. So while "fatigue" is a medical term for feeling because of illness, it also includes feeling tired from doing too much. There isn't a term to distinguish what we have from tiredness and exhaustion. So I prefer "fatigue," which has a medical association when compared to "exhausted" and "tired" which is associated with feeling from too much activity. Although, I don't like it either.
ME and CFS are labels. The illness is the same, but differing levels, differing stages, etc. I can see why CDC put it must last at least six months. If you have a virus and recovery is prolonged, then it might last a month or two to get the remnant fatigue gone. But what happened in Incline Village and Lyndonville and happens all over US and other countries is not just lingering fatigue from an infection you had a couple of months ago. It is much, much more.
In US, ME is CFS, as far as in the minds of doctors and CDC. Or, actually, better said, ME doesn't exist. As Andrew said, the illness in Tahoe included neurological problems and that illness was named CFS. So there is no distinction here. We all have CFS in the US, according to the way doctors diagnose.
And, the CDC diagnostic criteria for CFS does include cognitive dysfunction, including impaired memory or concentration as a primary symptom for CFS. It also includes PEM. Under other common symptoms it includes visual disturbances (blurring, sensitivity to light, eye pain or dry eyes.)
If I understand right, in doing their Georgia and Wichita study, they asked questions in their survey that would included many people with other illnesses. Someone correct me if I am wrong, but I think they used less of a standard in the survey compared to the diagnostic criteria they list.
I don't have the answers for how to distinguish all of this, depression fatigue from CFs / ME or post viral fatigue from others.
What I do know is that if you narrow CFS (or ME, or whatever label you want to give this illness) to only those with severe symptoms, you will eliminate many, who like me, have the illness but whose symptoms vary. As has been said before, it varies in individuals and varies according to stage of illness. I gradually got sick with fatigue and other symptoms creeping in more and more over three years from 2003 to 2006. Then in one night, I plummeted and pain started. This is when FM symptoms started. The fatigue was severe and did not ease for up. I was bedridden for four days at a time, to store up enough energy to have enough for running errands for four hours on the fifth day. And then, it was back to the bed. Of course, there were cognitive problems. I did not start to see improvement until nine months later. Since then, I have gradually improved, until a relapse this past October.
Whatever you want to call this illness, I have it. And for three years, my symptoms were mild, but gradually increasing. We can't exclude these people for it is just as harmful for them to not recognize the seriousness of their disease as it is for those of us with severe condition to have it belittled.
