Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS), and various other names, is a syndrome (or group of syndromes) of unknown and possibly multiple etiologies, affecting the central nervous system (CNS), immune, and many other systems and organs. There is no simple diagnostic test; CFS is a diagnosis of exclusion, although recent research indicates biological hallmarks of the syndrome, and a diagnostic test is predicted soon. Most definitions (other than the 1991 UK Oxford criteria) require a number of features, the most common being severe mental and physical exhaustion or depletion which is "unrelieved by rest" (according to the 1994 Fukuda definition), and is often worsened by even trivial exertion (controversially, the Oxford and Fukuda criteria require this to be optional only). CFS occurs more often, but not exclusively, in women, possibly due to immunological factors (women are overall more susceptible to similar disorders). CFS is most easily diagnosed when formerly active adults become ill, but it has been reported in persons of all ages, including young children and particularly teenagers.
Patients with this diagnosis commonly report many other symptoms which are far more onerous than these research diagnostic criteria; including pain, muscle weakness, loss of brain function, hypersensitivity, orthostatic intolerance, digestive disturbances, depression, immune system weakness, and cardiac and respiratory problems. These symptoms, like the syndrome's hallmark 'fatigue', range from mild to life-threateningly severe. Some cases resolve or improve over time, and where available, treatments bring a degree of improvement to many others. Most diagnostic criteria insist that these symptoms must be present for at least six months, and all insist on there being no other cause for the fatigue: i.e. the fatigue must be idiopathic, not caused by conditions such as radiation treatment for cancer, or diabetes. CFS remains a controversial diagnosis, and even its terminology and classification are controversial.
