Chronic relapsing myalgia (? Post viral): clinical, histological, and biochemical studies.

Byrne, E, Trounce, I, Dennett, X·Australian and New Zealand journal of medicine·1985

This study examined two patients with ongoing muscle pain that started after a viral-like illness and came and went unpredictably. Doctors found the patients had weak muscle fibers and signs that their muscles weren't producing energy as efficiently as they should. The findings suggest these patients may have a mild form of ME/CFS, and importantly, their muscle problems were real biological issues rather than caused by psychological factors.

Coxsackie B infection in a Scottish general practice.

Calder, B D, Warnock, P J·The Journal of the Royal College of General Practitioners·1984

This 1984 study from Scotland examined 38 patients with a prolonged illness involving multiple body system symptoms. Blood tests showed that nearly half of the patients tested had high levels of antibodies to Coxsackie B viruses, suggesting recent infection. The illness's pattern resembled ME/CFS, though the cases appeared gradually over four years rather than in sudden clusters.

Sporadic myalgic encephalomyelitis in a rural practice.

Keighley, B D, Bell, E J·The Journal of the Royal College of General Practitioners·1983

This study from 1983 examined 20 patients in a rural area who had long-lasting, hard-to-define illnesses. Researchers tested their blood for viral infections and found that 16 of these patients had high levels of Coxsackie B virus antibodies. Thirteen of these patients appeared to have myalgic encephalomyelitis (ME), while three had mainly heart-related symptoms. The findings suggest that a viral infection might be connected to ME, though the exact cause remains unclear.

Epidemic myalgic encephalomyelitis.

Bishop, J·The Medical journal of Australia·1980

This 1980 observational study by Bishop documented cases of epidemic myalgic encephalomyelitis (ME), a condition causing muscle pain, brain inflammation, and extreme fatigue. The study describes patterns observed during outbreaks of ME, helping early researchers understand how the illness affects groups of people.

Myalgic encephalomyelitis "an obscene cosmic joke"?

Church, A J·The Medical journal of Australia·1980

This 1980 case-control study examined patients with myalgic encephalomyelitis (ME/CFS) to better understand the condition. While the full details are limited, the study represents an early medical investigation into a disease that was not well understood at the time and was often dismissed by the medical community.

Post-infectious encephalomyelitis: some aetiological mechanisms.

Behan, P O·Postgraduate medical journal·1978

This 1978 study explores whether two different neurological conditions—acute disseminated encephalomyelitis (ADEM) and epidemic myalgic encephalomyelitis (a historical name for ME/CFS outbreaks)—might develop through similar biological mechanisms. The researcher identified multiple features these two diseases share and suggests that studying ADEM could help us better understand ME/CFS.

Electro-encephalographic investigations in myalgic encephalomyelitis.

Pampiglione, G, Harris, R, Kennedy, J·Postgraduate medical journal·1978

Researchers used EEG brain scans to study 36 young adults and 12 children with ME/CFS from the 1950s-1970s. They found that the brain activity patterns were slightly abnormal and varied between patients, suggesting that ME/CFS affects how the brain functions. The study suggests that future research should include regular EEG monitoring over 2-3 years to better understand these brain changes.

Benign myalgic encephalomyelitis.

Parish, J G·The British journal of psychiatry : the journal of mental science·1973

This 1973 study by Parish examined benign myalgic encephalomyelitis (ME), an early medical observation of the condition. The researcher documented cases of ME as a distinct medical illness. This historical paper represents one of the early clinical descriptions of the disease in the medical literature.

Benign myalgic encephalomyelitis.

Ramsay, A M·The British journal of psychiatry : the journal of mental science·1973

This 1973 paper by A.M. Ramsay describes myalgic encephalomyelitis (ME) as a benign condition affecting the nervous system and muscles. The author documented clinical observations of patients experiencing fatigue, muscle pain, and neurological symptoms. This early work helped establish ME as a distinct medical condition rather than a psychiatric illness.

Encephalomyelitis resembling benign myalgic encephalomyelitis.

Innes, S G·Lancet (London, England)·1970

This 1970 case report described patients with symptoms resembling myalgic encephalomyelitis (ME), including muscle pain, fatigue, and neurological symptoms. The study documented clinical presentations that looked similar to what we now call ME/CFS, helping establish early recognition of this condition in medical literature.

Benign myalgic encephalomyelitis.

The Medical journal of Australia·1970

This 1970 study examined cases of myalgic encephalomyelitis (ME), a condition causing muscle pain and fatigue. The researchers documented patient experiences and clinical features of the illness. This early medical documentation helped establish ME as a recognized clinical condition worthy of scientific investigation.

Encephalomyelitis resembling benign myalgic encephalomyelitis.

Lyle, W H·Lancet (London, England)·1970

This 1970 case study from The Lancet described patients with symptoms resembling myalgic encephalomyelitis (ME), a condition causing extreme tiredness, muscle pain, and brain fog. The researchers documented clinical cases to help doctors recognize and understand this illness pattern, which was not well-known at the time.

Concept of benign myalgic encephalomyelitis.

McEvedy, C P, Beard, A W·British medical journal·1970

This 1970 study reviewed 15 reported outbreaks of myalgic encephalomyelitis (ME) and concluded that many of these cases may have been caused by mass hysteria or misdiagnosis rather than a physical disease. The authors suggested that future similar cases should be called 'myalgia nervosa' to reflect a psychological rather than biological cause. This interpretation is now considered outdated, as modern research has identified real biological abnormalities in ME/CFS.

Benign myalgic encephalomyelitis in Lebanon.

Mourad, S, Chidiac, J·Le Journal medical libanais. The Lebanese medical journal·1969

This is an early observational study from 1969 describing cases of benign myalgic encephalomyelitis in Lebanon. The researchers documented patients with this condition, contributing to recognition of ME/CFS as a distinct illness in the Middle East during a period when the disease was still being identified and named around the world.

The psychiatric sequelae of benign myalgic encephalomyelitis.

Kendell, R E·The British journal of psychiatry : the journal of mental science·1967

This 1967 study examined whether people with benign myalgic encephalomyelitis (an early name for ME/CFS) experienced psychiatric symptoms or mental health challenges as a result of their illness. The researchers looked at patients with this condition to understand what psychological effects, if any, accompanied the physical symptoms of the disease.
