Below is an excerpt from the US Code (laws written by Congress) mentioning "CFS" as a "medically unexplained CMI." It seems to me almost certain that this was drafted by VA for Congress. It seems like there is a concerted effort afoot at VA to cement this nomenclature of "medically unexplained CMI" for all so called functional somatic syndromes including "CFS" and GWI. (thanks to Ren for finding this) I guess this is to make them all seem vague and also to go along with the Wessely School/DSM 5 effort to make it seem like they are all just one vague mental illness- somatization/ somatic symptom disorder. This makes me even more wary now of Mulrow since Deb Waroff found out that she was previously employed by VA. http://www.regulations.gov/#!documentDetail;D=VA-2010-VBA-0026-0001 "medically unexplained chronic multisymptom illness (such as chronic fatigue syndrome, fibromyalgia, and irritable bowel syndrome) that is defined by a cluster of signs or symptoms"
