"Although classified by the World Health Organization under Diseases of the nervous system, the etiology (cause or origin) of CFS is unknown, and multiple psychological and physiological factors may contribute to the development and maintenance of symptoms. There is no diagnostic laboratory test or biomarker for CFS." This is in the first paragraph of the Wikipedia article found by using the search words "Chronic Fatigue Syndrome." I don't know about you, but I really take issue with "psychological factors may contribute to the development.....yada yada." Does anybody know how we can get this taken out? It's inaccurate at best and serves to perpetuate the myth that somehow this is our fault at worst. In addition, it seems that a lot of the other information is out of date, including too-favorable reviews of CBT and GET.
