Myalgic Encephalomyelitis (ME) Criteria
ME International does not recognize CFS-Fukuda or ME/CFS-CCC or ME/CFS-SEID (aka IOM/NAM report) as an accurate diagnosis for ME.
MEI's Myalgic Encephalomyelitis - Understanding Diagnosis (20:37 video)
This video discusses the history of ME, the lived experience, including recognition of the most severe patients, a full description of how to diagnose using the International Consensus Criteria as well as the challenges of getting a diagnosis. Proper diagnosis is vital for patients to get proper treatment.

This video is a condensed version of the above video and discusses the history of ME, the lived experience, including recognition of the most severe patients, and the challenges of getting a diagnosis.
Criteria Comparison Charts
1. Multiple Criteria Comparison
Covers Holmes, Fukuda, Canadian Consensus, International Consensus & Institute of Medicine.
NOTE: IOM (NAM) criteria, originally labeled SEID, took over the ME/CFS label and was posted on the CDC website since at least 2018.

2. CFS vs. M.E.
'CFS' and M.E. comparison chart. This chart illustrates the many differences between Chronic Fatigue Syndrome (CFS) and Myalgic Encephalomyelitis (M.E.). As this chart shows, despite what many groups claim, CFS and M.E. are not the same.

3. ME-ICC vs ME/CFS-SEID
Compares criteria between ME as per the ICC and ME/CFS-SEID as per the IOM report.

GETTING AN ME DIAGNOSIS USING THE ICC
The ME-ICC questionnaire from www.MEadvocacy.org/resources is a useful tool to understand if ME is a reasonable diagnosis to consider. Circling the symptoms and presenting this to your doctor (and family/friends) can help simplify the challenge of explaining the breadth/depth of ME.
"Do I fit the ICC?": English en Español
The next step is to confirm the ME diagnosis. The IC Primer guides doctors to diagnose, treat and rule out other diseases.
The ICC alone is not enough to confirm an ME diagnosis.
See an easy-to-read 2-page Dr. handout regarding the IC Primer HERE.
ME (G93.3 as of 5/24/20) and CFS (R53.82 as of 5/24/20) are two separate ICD diagnosis codes. Combining two different patient groups under one label (ME/CFS) leads to inadequate treatments for #pwME.
These need to be kept separate.
GERMANY uses the CFS label with the G93.3 code.
DEUTSCHLAND verwendet das CFS-Label mit dem Code G93.3.
G93.3 Chronisches Müdigkeitssyndrom [Chronic fatigue syndrome]
Inkl.: Chronisches Müdigkeitssyndrom bei Immundysfunktion
Myalgische Enzephalomyelitis
Postvirales Müdigkeitssyndrom

Review of case definitions for ME/CFS
Lim and Son (Republic of Korea)
This paper gives a good history of the 25 case definitions/diagnostic criteria created since 1986, based on three conceptual factors (etiology, pathophysiology, and exclusionary disorders). ~ MEI
"...ME/CFS has been named differently (e.g., postviral fatigue syndrome, neurasthenia) depending on the perspectives of the researchers; likewise, diagnostic criteria or case definitions have also been changed accordingly." Conclusions: "In this review, we found three key factors that have affected ME/CFS case definitions: etiology, pathophysiology, and exclusionary disorders. These factors have impacted the specification of the main symptoms, required conditions, and range of inclusive and exclusive symptoms/disorders in the development of case definitions." - 29 July 20

Chronic Fatigue Syndrome (CFS) and Other Criteria
Due to decades of misinformation about diagnosing ME, we suggest everyone diagnosed with ME, CFS, ME/CFS-CCC, or systemic exertion intolerance disease (SEID) (and similar diseases) research which criteria most closely matches their experience.
