The report noted that while there is current progression in the study of ME/CFS using molecular and physiologic methods, further studies need to be conducted to determine the natural history of the disease, as well as to better understand onset, duration, severity, recovery, and functional losses.
The complete study is published in the Institute of Medicine’s February 2015 report brief.
