New research may have found a way to make the difficult task of diagnosing ME/CFS much easier through the identification of a new reliable biomarker.
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic condition causing extreme fatigue and debilitation, sleep problems, issues with mentation, and other symptoms. The cause is unknown, but immune system alterations, stress, or infectious processes may be associated with the onset of the condition. The Institute of Medicine (IOM) reported in 2015 that over 800,000 (and perhaps up to 2.5 million) Americans have ME/CFS, with most cases going undiagnosed. The diagnostic challenge is well known, and there has not been a specific test that can confirm ME/CFS. Usually, a number of other conditions must be ruled out before making a diagnosis of ME/CFS.
