How is CFIDS related to CFS?
Some patients and patient advocacy groups feel the name CFS trivializes the syndrome. Thus, these groups use the name CFIDS (Chronic Fatigue and Immune Dysfunction Syndrome). However, the scientific literature refers to the illness as Chronic Fatigue Syndrome (CFS). CFS was designated by a group of researchers to encompass the chief symptom of the syndrome without implying a causative agent. Medical professionals advise the name will remain “CFS” until research identifies the etiological (causal) agent.
