Chronic fatigue syndrome (CFS) is a disorder characterized by persistent fatigue that lasts for more than 6 months, has no clear cause, and is accompanied by cognitive difficulties. CFS was initially termed "encephalomyalgia" (or "myalgic encephalomyelitis") because British clinicians noted that the essential clinical features of CFS included both an encephalitic component (manifesting as cognitive difficulties) and a skeletal muscle component (manifesting as chronic fatigue). More recently, the US Institute of Medicine proposed that the condition be renamed "systemic exertion intolerance disease" to better reflect the condition's hallmark defining symptom: postexertional malaise.
