I previously wrote an article on here discussing the CDC’s current study that shows the rate of CFS in individuals is 6 – 10 times higher than what was found in previous studies. You can read that article by clicking here.
Leonard Jason, PhD at DePaul University and CFS researcher stated, “It is at least possible that the 2.54% to 2.6% CFS rates in both the United States and Great Britain are due to a broadening of the case definition and possible inclusion of cases with primary psychiatric conditions.CFS and depression are two distinct disorders, however, even if they share a number of common symptoms. Most importantly, the erroneous inclusion of people with primary psychiatric conditions in CFS samples will have detrimental consequences for the interpretation of both epidemiologic and treatment efficacy findings.
More information on this study and Dr. Jason’s findings can be read at the International Association for Chronic Fatigue Syndrome (IACFS/ME).
