Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is an illness with a long history of controversy. Some professionals within the medical community do not recognize ME/CFS as a genuine condition, nor is there agreement on its prevalence. There has been much disagreement over the pathophysiology of chronic fatigue syndrome, how it should be diagnosed, and how to treat it.
The diagnosis is controversial, and its etiology is still not fully understood. Alternative names to describe the condition(s) have been used over time throughout the world. Patient groups have criticized the name "chronic fatigue syndrome", saying that it trivializes the illness.
Neglect and lack of awareness
ME/CFS suffers from a lack of awareness among clinical professionals. Despite being a relatively common and disabling disease, a large proportion of professionals are either unaware or dismissive of it. This often leads to patient neglect, which happens in clinical, government, bureaucratic, and research settings.
Lack of awareness in clinical settings
Despite ample evidence that ME/CFS is an organic disease, many clinicians do not recognise it as genuine or underestimate its seriousness. A 2020 literature review found that "a third to a half of all GPs did not accept ME/CFS as a genuine clinical entity and, even when they did, they lacked confidence in diagnosing or managing it."
A substantial proportion of medical schools do not teach about ME/CFS, and the large majority do not provide clinical exposure to ME/CFS patients. In 2021, the UK NICE found that "medical students reported that there is little or no formal training on ME/CFS in the medical curriculum and that their knowledge often comes from media".
Training influences attitudes towards ME/CFS. One study conducted a relatively brief seminar presenting factual information on the illness to a cohort of fourth year medical students. The authors concluded the information provided was associated with a more favorable attitude toward ME/CFS.
Neglect of patients

Governments, medical institutions, and the medical community have been criticised for neglecting people with ME/CFS. George Monbiot, a journalist for the Guardian, called the neglect and its consequences "the greatest medical scandal of the 21st century". Individuals with the condition describe the struggle for healthcare and legitimacy due to what is described as bureaucratic denial of the condition because of its lack of a known etiology. Institutions maintain the exclusion of patient support by rhetorical arguments of the open-endedness of science to delay new findings of fact.
A 2006 investigation by a group from the Parliament of the United Kingdom found there was not enough support in the UK for CFS patients in terms of access to government benefits and health care.
Mass hysteria accusations
Epidemic cases of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) had often historically been described as cases of mass hysteria, suggested by a paper written by psychiatrists McEvedy and Beard in 1970, provoking criticism in letters to the editor of the British Medical Journal by attending physicians, researchers, and nurses who fell ill.
The psychiatrists were criticized for not investigating the patients they described, and their conclusions have been refuted. In 1978 a symposium held at the Royal Society of Medicine (RSM) concluded that epidemic myalgic encephalomyelitis was a distinct disease entity.
However, the idea that ME/CFS may be culturally mediated persisted in some quarters. In her 1997 book Hystories: Hysterical Epidemics and Modern Culture, literary critic and feminist Elaine Showalter argued that the illness is a "hysterical narrative", a modern manifestation of hysteria, a self-perpetuating "cultural symptom of anxiety and stress" historically assigned to women.
Harms to patients
Harmful treatments
Reports of medical harm to patients resulting from the use of cognitive behavioral therapy (CBT) as a primary treatment and the use of graded exercise therapy (GET) have arisen. A controversial clinical trial of the Lightning Process in children, led to it being specifically forbidden in the NICE guidelines. A number of publications by Esther Crawley promoting GET have been corrected due to inaccurate ethics statements.
Deaths and suicide
Studies show medical neglect, trivialisation, and psychologization have contributed to increased risk of suicide in patients suffering from ME/CFS. In some severe cases, neglect by clinicians has led to complications of the disease which ultimately led to the death of the patient. Some patients with severe and very severe ME/CFS are unable to swallow or properly digest, when this is neglected or misdiagnosed as a psychological condition (such as anorexia nervosa), malnutrition can follow, with a risk of death. Proper care for patients with severe feeding problems stipulates total parenteral nutrition for short term cases and using feeding tubes for long term cases.
A notable case is that of Maeve Boothby O'Neill, a 27-year-old woman who died from very severe ME/CFS in 2021. As her condition gradually worsened, she became too unwell to properly feed and hydrate herself. At first the NHS doctors gave her feeding aids, but insisted upon feeding her much more than her body could handle which exacerbated her condition through post-exertional malaise. The only feasible option left was total parenteral nutrition, but due to the doctor's belief that her condition was largely psychological, they refused this route. A month later, she died of malnutrition. An inquest into Maeve Boothby O'Neill's death was opened by the Exeter and Devon Coroners, and is currently ongoing. Dr. Anthony Hemsley, the director of the Royal Devon and Exeter NHS Foundation Trust, has testified that the NHS has no policy and no facilities for treating severe (housebound) or very severe (bedbound) patients anywhere in the United Kingdom.
Misdiagnosis, under-diagnosis, and delays in diagnosis
Because of a lack of awareness and education about ME/CFS in the medical community delays in diagnosis and misdiagnosis are common. A large proportion of ME/CFS patients are undiagnosed; its true prevalence is therefore unknown. ME/CFS patients can be misdiagnosed with a wide variety of conditions, common ones include psychosomatic disease, depression, burnout, and neuresthenia. It is common for diagnosis to take over five years post disease onset, and visits to a large number of medical professionals.
Involuntary psychiatric hospitalisation
There have been reported cases of forced psychiatric hospitalisation of ME/CFS patients. In these cases clinicians wrongly assumed ME/CFS was of psychological origin, or misdiagnosed a mental illness.
A notable case is that of Sophia Mirza. Mirza was forcibly removed from her home and sectioned for two weeks by her doctors, who had come to believe her condition was psychosomatic, an action which her mother and sister said severely worsened her condition, through post exertional malaise. Her health deteriorated after being released from the psychiatric unit, and two years later she died. An inquest into her death revealed it to be due to renal failure due to dehydration as a result of chronic fatigue syndrome.
Naming
There has been much historical debate over whether to use the term Myalgic Encephalomyelitis or Chronic Fatigue Syndrome to describe the disease, therefore, the compromise Myalgic Encephalomyelitis/Chronic Fatigue Syndrome is often used.
The term chronic fatigue syndrome is criticised for focusing on a single symptom, while its use has lead many to confuse ME/CFS with general chronic fatigue. The term "fatigue" trivialises the illness and discourages research into potential treatments. According to a survey of medical trainees at a school in the United States, a condition described as "chronic fatigue syndrome" is considered less serious than a condition described as "myalgic encephalopathy".
The term myalgic encephalomyelitis has also been criticised, as the symptom myalgia (muscle pain) is not experienced by everyone with the disease. Additionally, before ME/CFS was considered a biological condition, the name ME was seen as reinforcing the illness as it "legitimised" patient's symptoms.
In 2015 the National Academy of Medicine recommended changing the name to Systemic Exertion Intolerance Disease (SEID) in their report "Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Redefining an Illness"'. However, this new name was not widely adopted.
Disability compensation
Despite being a disabling condition that leaves around 75 percent of patients unable to work, people with ME/CFS are often dismissed when applying for disability compensation.
UK psychosocial controversy
Despite being classified as a biological illness by national health bodies, the Department for Work and Pensions classifies ME/CFS as a psychosocial illness, which means sufferers are entitled to lower benefits. A 2006 report by the UK Parliamentary Group on Scientific Research into Myalgic Encephalomyelitis stated that: "CFS/ME is defined as a psychosocial illness by the Department for Work and Pensions (DWP) and medical insurance companies. Therefore, claimants are not entitled to the higher level of benefit payments. We recognise that if CFS/ME remains as one illness and/or both remain defined as psychosocial then it would be in the financial interest of both the DWP and the medical insurance companies." The Group called for investigation of what they called, "numerous cases where advisors to the DWP have also had consultancy roles in medical insurance companies. Particularly the Company UNUMProvident. Given the vested interest private medical insurance companies have in ensuring CFS/ME remain classified as a psychosocial illness there is blatant conflict of interest here."
The Secretary of State for Work and Pensions responded that "Entitlement to Disability Living Allowance depends on the effects that severe physical or mental disability has on a person's need for personal care and/or their ability to walk, and not on particular disabilities or diagnoses. The benefit is available to people with myalgic encephalomyelitis (which can have a physical basis or a psychological basis, or can be due to a combination of factors) on exactly the same terms as other severely disabled people, and they can qualify for it provided that they meet the usual entitlement conditions." This runs contrary to current scientific evidence which shows ME/CFS is "unambiguously biological".
