Chronic fatigue syndrome (CFS) is a complex disorder characterized by profound fatigue and other related symptoms. Standards for the diagnosis of CFS have been defined by researchers at the Centers for Disease Control and Prevention (CDC). These include excessive fatigue that does not respond to bed rest, combined with four or more of the following symptoms: substantial impairment in short-term memory or concentration; sore throat; tender lymph nodes; muscle pain; pain in multiple joints without redness or stiffness; headaches of a new type, pattern or severity; unrefreshing sleep; and a general feeling of ill health (malaise) for up to 24 hours after exertion.
Chronic fatigue syndrome has generated significant debate and controversy in the medical community. It remains a poorly understood and potentially debilitating illness. Scientists believe chronic fatigue syndrome is not contagious and that multiple factors including immunological, genetic, environmental ones working in combination cause the development of chronic fatigue syndrome. Laboratory tests (blood, urine, etc.) are of little value in diagnosing the syndrome.
