Research
Numerous research studies have been conducted on chronic fatigue syndrome (CFS), also known as chronic fatigue and immune dysfunction syndrome (CFIDS). Most of the research has involved the search for a cause, efficacious treatment, prevalence rates and demographic characteristics.

Research articles and abstracts are available on the The CFIDS Association of America Web site or by contacting the Association.
