"The disorder is not a manifestation of mass hysteria.  It is concluded that the disease is recognizable in its epidemic form on clinical and epidemiologic grounds and therefore may properly be considered a clinical entity.  The disease is probably due to infection by an unknown agent or group of related agents."
-E.D. Acheson, D.M., M.R.C.P.-

Often called "The Disease of a Thousand Names," the first ME definitions arose from descriptions of many historic epidemics, post-viral in nature.   Encephalitis Lethargica, Epidemic neuromyasthenia, Tapanui flu, Iceland disease, Akureyri disease, Atypical poliomyelitis, Atypical multiple sclerosis are just a few of dozens of similarly described epidemics throughout history.  Dr. Byron Hyde notes 63 outbreaks from 1934 to 1990 in his book The Clinical and Scientific Basis of M.E. /CFS,  but lists vary, with similar outbreaks described as early as  1917, and with Dr. Hyde himself naming his foundation after Florence Nightingale (1820-1910), who was stricken with an ME like illness.

In 1956, Dr. A. Melvin Ramsay formally coined the name myalgic encephalomyelitis in a paper describing the 1955 epidemic at Royal Free Hospital in London.  In 1962 the distinguished neurologist Lord Brain included ME in the standard textbook of neurology. ME was then formally classified as a disease of the central nervous system in the World Health Organization's 8th version of the International Classification of Diseases, ICD-8, in 1969.

The articles below cover many of the historic ME outbreaks, while we've summarized the ME/CFS definitions and descriptions from more recent history (since the mid-1980s) in the pages on the link bar to the right.


A New Clinical Entity?
(May 26, 1956 article in the British medical journal The Lancet. Encapsulates descriptions of epidemics from 1917 through 1955.)

The Clinical Syndrome Variously Called Benign Myalgic Encephalomyelitis, Icelandic Disease, and Epidemic Neuromyasthenia.
(E.D. Acheson, D. M., M.R.C.P., The American Journal of Medicine, April 1959.  One of the first comprehensive definitions. [see above quote])


Although Dr. John Richardson had published more contemporary articles on ME, he had over 40 years experience of caring for ME patients and studying ME history.  So we have included some of his work here...

Myalgic Encephalomyelitis: Guidelines for Doctors
Journal: J of Chronic Fatigue Syndrome, Vol. 10(1) 2002, pp. 65-80
Author: John Richardson, MB BS

In this article, Dr. Richardson covers history, initiating illness, prevalence and clinical diagnosis,  all body systems affected by ME/CFS and treatments.

Excerpt:

"HISTORY
For those of us who are involved in the care of patients with this condition, the recorded work of Biorn Signurdsson (1913-1953) in connection with the Akureyn outbreak in Iceland which affected over 1000 patients, both children and adults was repeated by Melvin Ramsay when he was involved in the outbreak in his hospital which became known as the "Royal Free Disease" but defined by him as Myalgic Encephalomyelitis. This was followed by an excellent monograph in 1969 by Luis Leon-Sotomayor published by Pageant Press International Corp., New York and entitled, "Epidemic Diencephalomyelits; A Possible Cause of Neuropsychiatric, Cardiovascular and Endocrine Disorders." Since then many colleagues from the U.K. and other countries have demonstrated the pathological systemic consequences which may occur after a viral illness and have long term effects. All this work has been pursued by many colleagues in the U.K. and abroad since then, amongst whom are 72 who contributed to the book of more recent origin and published by the Nightingale Research Foundation entitled The Clinical and Scientific Basis of M.E. /CFS."
