Chronic fatigue syndrome (CFS) is a complicated disorder characterized by extreme fatigue that can’t be explained by any underlying medical condition. The fatigue may worsen with physical or mental activity, but doesn’t improve with rest.
This condition is also known as systemic exertion intolerance disease (SEID) or myalgic encephalomyelitis (ME). Sometimes it’s abbreviated as ME/CFS.(Information from Mayo Clinic)
Typically, for an official diagnosis of CFS, an individual must have been sick for six (6) or more months with fatigue severe enough to reduce the individuals activity level by at least 50% and at least four of the following symptoms: impairment in short-term memory or concentration, sore throat, tender lymph nodes, muscle or multi-joint pain without swelling or redness, headaches, unrefreshing sleep, and post-exertional malaise. Physicians must rule out other causes of the symptoms.

National CFIDS Foundation
Founded in 1997 by two 14 year CFIDS (Chronic Fatigue Immune Dysfunction Syndrome) advocates, the goals of the Foundation are to help fund medical research to find a cause, expedite treatments and eventually a cure for this devastating disease. The NCF also strives to provide information, education, and support to those people who have CFIDS (also known as chronic fatigue syndrome (CFS), myalgic encephalomyelitis (ME) and many other names) — as well as related illnesses such as Gulf War Illness (GWI) and Multiple Chemical Sensitivities (MCS).
