I just did some copyediting and noticed that we're using some not-necessarily-reliable sources like blogs and ProHealth. Since we currently have no scientific guidelines up, I've left these untouched. I think the gist of what they present is correct, even if it may come from a specific perspective, but if our scientific guidelines later insist on peer-reviewed sources and the like, these will obviously need to be removed, or better sources found.

Moved from main page[edit source]

Chronic fatigue syndrome and ME/CFS were unnecessarily duplicative of myalgic encephalomyelitis, the main disease page.

History[edit source]

Myalgic encephalomyelitis[edit source]

  • 1956, The name Myalgic Encephalomyelitis first appeared in medical literature.[1]

Chronic fatigue syndrome[edit source]

ME and CFS used interchangeably[edit source]

  • 1990's - 2000's, "The criteria focused on fatigue and not as much on the encephalitic (inflammation of the brain) features of the disorder." Doctors began using ME and CFS interchangeably due to the broad CFS definition.[5]

The ME name was not fully accepted by the medical and government health agencies while CFS was not found to be acceptable by patients and some health practitioners.

ME/CFS criteria developed[edit source]

  • 2006, Rich Carson, founder of ProHealth, started a name change campaign.[7]

Why the acronym ME/CFS is used[edit source]

ME/CFS is a hybrid term for a community and disease in transition. It combines the older and more broadly recognized “CFS” with the less stigmatized “ME,” which is becoming more commonly used. Many governments and health authorities have recently adopted the term “ME/CFS,” which has evolved to become the most accessible term to meet the needs of the broadest audience. The Solve ME/CFS Initiative adopted this name so that our organization would be accessible and understandable to medical, academic, patient, and government audiences alike.

Number afflicted and lost wages[edit source]

ME/CFS afflicts up to 2.5 million Americans (and an estimated 17 million worldwide) and in the USA the total economic costs are $17-24 billion a year. The US numbers are from the Institute of Medicine report (IOM report) which used the Fukuda criteria (for defining CFS in research) and CCC (which defines either ME or CFS in research or in a clinical setting).[10][11]

Criteria comparison[edit source]

From CFS vs SEID, Pg. 13[12]
Table 1
88% SEID - (Developed by the IOM report) PEM Required
92% Fukuda criteria - (CFS) (Used by committee that developed IOM report) PEM Optional
76% CCC - (ME/CFS) (Used by committee that developed the IOM report) PEM Optional
61% Four-symptom criteria - (ME/CFS) PEM Required
60% ICC - (ME) PEM Required

There are fewer ME-ICC patients and the numbers of afflicted and financial impact from the IOM report are not correctly attributed to ME or CFS but instead to ME/CFS as Fukuda criteria and CCC were used by the authors of the IOM report.[13]

Results: At 6 months of illness, SEID criteria identified 72% of all subjects, similar to when Fukuda criteria (79%) or the CCC (71%) were used, whereas the ME-ICC selected for a significantly lower percentage (61%, p < .001). When severity/frequency thresholds were added to the Fukuda criteria, CCC and ME-ICC, the percentage of these subjects also fitting SEID criteria increased to 93%, 97%, and 95%. Eighty-seven percent of SEID subjects endorsed cognitive impairment and 92%, OI; 79% experienced both symptoms.
Conclusions: SEID criteria categorize a similar percentage of subjects as Fukuda criteria early in the course of ME/CFS and contain the majority of subjects identified using other criteria while requiring fewer symptoms. The advantage of SEID may be in its ease of use.

When Fukuda criteria, CCC and ME-ICC have severity/frequency thresholds added patients will meet SEID criteria. This is advantageous in a clinical setting as patients can be diagnosed by a Primary/GP/Family Doctor using SEID and then the patient can go through the process of receiving a CFS, ME/CFS or ME diagnosis from a doctor/researcher using Fukuda, CCC or ME-ICC until a Biomarker is found.

Controversy[edit source]

  • It is believed by some in the ME, CFS and ME/CFS community that the name Chronic Fatigue Syndrome and then the Myalgic Encephalomyelitis/Chronic Fatigue Syndrome name are a product of medical insurance companies, possibly in an effort to define the disorder as a behavioral illness similar to hypochondria or malingering. Insurance companies could benefit from this viewpoint, since behavioral illnesses are much less expensive to treat than physical illnesses, and in many cases, are not covered by insurance at all.[14]
