Myalgic encephalomyelitis: International Consensus Criteria
- Source: Journal of International Medicine, July 20, 2011
The label 'chronic fatigue syndrome' (CFS) has persisted for many years because of lack of knowledge of the etiological agents and of the disease process.
In view of more recent research and clinical experience that strongly point to widespread inflammation and multisystemic neuropathology, it is more appropriate and correct to use the term 'myalgic encephalomyelitis' (ME) because it indicates an underlying pathophysiology. [bolding ours]
It is also consistent with the neurological classification of ME in the World Health Organization's International Classification of Diseases (ICD G93.3).
Consequently, an International Consensus Panel consisting of clinicians, researchers, teaching faculty and an independent patient advocate was formed with the purpose of developing criteria based on current knowledge.
Thirteen countries and a wide range of specialties were represented.
Collectively, members have approximately 400 years of both clinical and teaching experience, authored hundreds of peer reviewed publications, diagnosed or treated approximately 50,000 ME patients, and several members coauthored previous criteria.
The expertise and experience of the panel members as well as PubMed and other medical sources were utilized in a progression of suggestions/ drafts/reviews/revisions.
The authors, free of any sponsoring organization, achieved 100% consensus through a Delphi type process.
The scope of this paper is limited to criteria of ME and their application. Accordingly, the criteria reflect the complex symptomatology.
Operational notes enhance clarity and specificity by providing guidance in the expression and interpretation of symptoms.
Clinical and research application guidelines promote optimal recognition of ME by primary physicians and other health care providers, improve consistency of diagnoses in adult and pediatric patients internationally, and facilitate clearer identification of patients for research studies.
