Chronic Fatigue And Immune Dysfunction Syndrome
Also called chronic fatigue syndrome, chronic Epstein-Barr virus, myalgic encephalomyelitis, and Yuppie flu, this syndrome is characterized by incapacitating fatigue. The patient's symptoms may wax and wane, but they're often severely debilitating and can last for months or years.
Although most prevalent among professionals in their 20s and 30s, the syndrome affects people of all ages, occupations, and income levels. The diagnosis is more common in women than in men or children, especially women under age 45. Sporadic incidence and epidemic clusters have been observed.
The precise cause of chronic fatigue syndrome isn't known. Although the cause originally was attributed to the Epstein-Barr virus, that hypothesis has since been rejected on the basis of serologic and epidemiologic observation.
Several other causative viruses have been proposed and investigated, including cytomegalovirus, herpes simplex virus types 1 and 2, human herpesvirus 6, Inoue-Melnick virus, human adenovirus 2, enteroviruses, measles virus, and a retrovirus that resembles human T-cell lymphotropic virus type II. The onset in some patients suggests a viral illness, but whether the syndrome results from a new or a reactivated infection isn't known.
Another theory holds that some symptoms may result from an overactive immune system. In addition, genetic predisposition, age, hormonal balance, neuropsychiatric factors, sex, previous illness, environment, and stress appear to have a role in the syndrome.
