“The term “myalgic encephalomyelitis” was coined by the British physician, Dr. Melvin Ramsay, in the 1950’s when he described an outbreak that occurred in London. It is still used by British and many European specialists instead of the American-coined term, “chronic fatigue syndrome.” – Dr. Charles Lapp
“The current CDC Myalgic Encephalomyelitis/Chronic Fatigue Syndrome diagnostic criteria is also known as the Systemic Exertion Intolerance Disease (SEID) criteria; SEID was a the new name proposed for chronic fatigue syndrome which is not in use. The proposed name and acronym SEID is meant to hone in on key aspects of ME/CFS. Systemic would give credence to the disease being body wide. Exertion Intolerance would key doctors into understanding that the patient cannot tolerate exertion.[3]Disease gave the self-explanatory label of being an organic biological disease.” – MEACTION Encyclopedia
