Just an FYI on the statistic from Jason's study... it is always cited backwards. the correct statistic is 38% of people with MDD qualify as CFS under Reeves' criteria. This is not the same as 38% of the CFS cohort (which is how I generally see the statistic presented). There are many more people with so-called "affective disorders" than CFS, and it is a much larger percent of CFS than 30-40%. In fact, Jason notes that the incidence of "CFS" jumped by 10-fold with the introduction of the so-called Empirical criteria, to coincidentally approximate the incidence of the "affective disorders". So it is highly unlikely for any more than 10% of Reeves disease to be Fukuda-CFS. It is probably much less than 10%, given the fact that CDC has taken to criticising Fukuda-diagnostic S&S like tender lymphs and Fukuda-update noted S&S like balance difficulties... as indicating the patient probably does not have CFS.
