Myalgic encephalomyelitis (ME), also referred to in the literature as chronic fatigue syndrome (CFS), is a complex disease involving profound dysregulation of the central nervous system (CNS) [1-3] and immune system [4-8], dysfunction of cellular energy metabolism and ion transport [9-11], and cardiovascular abnormalities [12-14]. The underlying pathophysiology produces measurable abnormalities in physical and cognitive function and provides a basis for understanding the symptomology.

Some symptoms of the Fukuda criteria overlap with depression whereas the Canadian Consensus Criteria [20] differentiate ME patients from those who are depressed and identify patients who are more physically debilitated and have greater physical and cognitive functional impairments [21].

The six-month waiting period before diagnosis is no longer required. No other disease criteria require that diagnoses be withheld until after the patient has suffered with the affliction for six months. Notwithstanding periods of clinical investigation will vary and may be prolonged, diagnosis should be made when the clinician is satisfied that the patient has ME rather than having the diagnosis restricted by a specified time factor. Early diagnoses may elicit new insights into the early stages of pathogenesis; prompt treatment may lessen the severity and impact.

>--< The pathological low threshold of fatigability of ME described in the following criteria often occurs with minimal physical or mental exertion, and with reduced ability to undertake the same activity within the same or several days. >--< Individuals meeting the International Consensus Criteria have myalgic encephalomyelitis and should be removed from the Reeves empirical criteria and the National Institute for Clinical Excellence (NICE) criteria for chronic fatigue syndrome. These guidelines are designed specifically for use by the primary care physician in the hope of improving rapid diagnosis and treatment by first-line medical care providers. This may result in the development of an additional short form version that would build on the relationships linking symptoms to formulate an abbreviated screening protocol. For the first time clinical, paediatric and research applications are provided, which will advance the understanding of myalgic encephalomyelitis and enhance consistency of diagnoses internationally. The compulsory critical criteria allow comparable data to be collected in various locations and may assist in developing consistent biomarkers and further insights into the mechanism and etiology of myalgic encephalomyelitis.
