The Life Span Institute at the University of Kansas: "Chronic Fatigue syndrome, also called chronic fatigue and immune dysfunction syndrome, describes a serious chronic condition in which individuals experience six or more months of fatigue accompanied by physical and cognitive symptoms. Do not use terms such as Yuppie Flu, malingering, and hypochondriasis as they are pejorative, imply personality disorders, and are not scientifically supportable. Say person with chronic fatigue syndrome."
