Many different diagnoses have been suggest for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS).[1][2][3] A number of the common differential diagnoses also commonly occur in patients with ME/CFS, so they should not be regarded as conditions that automatically exclude the diagnosis of ME/CFS.[2][1]

"Many syndromes and diseases have the symptom of chronic fatigue as the most distressing, unremitting complaint. It is the consideration of these other possible causes - their confirmation or exclusion - which constitutes the discipline of ditferential diagnosis. Syndromes which are "look alikes," or indeed identical syndromes, include post-viral states, chronic viraemias, neoplastic syndromes, neurological diseases, especially in the eariy substantial stages of neuromuscular disease, psychiatric disorders, and some forms of both organic and inorganic poisoning. To mislabel any one of these as CFS or ME, or to leave a patient with CFS undiagnosed as such, means the discipline of differential diagnosis has failed."[7]:4-5

myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
