Chronic Fatigue Syndrome (CFS), also known as Myalgia Encephalomyelitis (ME), is characterized by severe, persistent fatigue lasting more than six months, which is not alleviated by rest and significantly reduces previous levels of activity (Centres for Disease Control and Prevention [CDC], 2023). The Institute of Medicine (IOM) criteria require the presence of post-exertional malaise (PEM), unrefreshing sleep, and either cognitive impairment or orthostatic intolerance (CDC, 2023).
The aetiology of CFS/ME is multifactorial, involving genetic predisposition, infections, immune system dysfunction, endocrine system abnormalities, and psychological factors (MSD Manuals, 2023; Verywell Health, 2023). Pathogenesis includes neuroinflammation, mitochondrial dysfunction, oxidative stress, autonomic nervous system dysfunction, and gut microbiome alterations (Oxford Academic, 2023; Springer, 2023).
Effective symptom management includes pacing and energy management, cognitive behavioural therapy (CBT), symptom-specific medications, diet and nutrition, physical therapy, sleep hygiene, stress management, support systems, assistive devices, and regular medical check-ups (National Institute for Health and Care Excellence [NICE], 2023; National Health Service [NHS], 2023; Verywell Health, 2023; Sleep Foundation, 2023). Rehabilitation focuses on pacing and energy management, CBT, graded exercise therapy (GET), symptom management, psychological support, and a multidisciplinary approach (NICE, 2023; BMJ, 2023). Emerging therapies like neuromodulation and ongoing pharmacological research are also being explored (Cambridge et al., 2023).
Chronic Fatigue Syndrome (CFS), also known as Myalgia Encephalomyelitis (ME), is a complex and debilitating disorder characterized by profound fatigue that is not alleviated by rest and is exacerbated by physical or mental activity (CDC, 2023). This condition significantly impairs the ability to perform daily activities and can reduce quality of life. The fatigue experienced by individuals with CFS/ ME is often accompanied by a range of other symptoms, including cognitive impairments, unrefreshing sleep, and post-exertional malaise (PEM), which is a worsening of symptoms following physical or mental exertion (NICE, 2023).
The aetiology of CFS/ME remains unclear, but it is believed to be multifactorial, involving genetic predisposition, infections, immune system dysfunction, and endocrine abnormalities (MSD Manuals, 2023; Verywell Health, 2023). The pathogenesis of the condition includes neuroinflammation, mitochondrial dysfunction, and autonomic nervous system dysregulation, which contribute to the diverse and persistent symptoms experienced by patients (Oxford Academic, 2023; Springer, 2023).
Effective management of CFS/ME requires a comprehensive and multidisciplinary approach. Current evidence-based treatments focus on symptom management, including pacing and energy management, cognitive behavioural therapy (CBT), and graded exercise therapy (GET) (NICE, 2023; BMJ, 2023). These interventions aim to improve functional capacity and quality of life while minimizing the risk of symptom exacerbation.
Understanding CFS/ME is crucial for developing effective treatment strategies and providing appropriate support to those affected by this challenging condition. Ongoing research explores the underlying mechanisms and potential therapeutic options to enhance patient outcomes (Cambridge et al., 2023).
Definition
Chronic Fatigue Syndrome (CFS), also known as Myalgia Encephalomyelitis (ME), is defined by the Centres for Disease Control and Prevention (CDC) as severe fatigue lasting longer than six months, accompanied by at least four of the following symptoms:
• Post-exertional malaise
• Unrefreshing sleep
• Impaired memory or concentration
• Muscle pain
• Polyarthralgia (multiple joint pain)
• Sore throat
• Tender lymph nodes
• New headaches
Definition and Diagnostic Criteria
The Centres for Disease Control and Prevention (CDC) criteria for diagnosing CFS/ME include:
Severe fatigue:
• Persistent or relapsing fatigue lasting for more than six months.
• The fatigue is not due to ongoing exertion, is not alleviated by rest, and significantly reduces previous activity levels.
Additional Symptoms
The presence of at least four of the following symptoms:
• Post-Exertional Malaise (PEM): Worsening of symptoms following physical or mental exertion that was previously tolerated.
• Unrefreshing Sleep: Feeling unrefreshed after a whole night’s sleep.
• Cognitive Impairment: Problems with memory, concentration, and information processing.
• Muscle Pain: Persistent muscle pain.
• Polyarthralgia: Pain in multiple joints without swelling or redness.
• Sore Throat: Frequent or recurring sore throat.
• Tender Lymph Nodes: Tenderness in the lymph nodes, particularly in the neck or armpits.
• New Headaches: New types, patterns, or severity of headaches.
Aetiology and Pathogenesis: A Quick Snapshot
Aetiology: The exact cause of CFS/ME is unknown, but it is believed to be multifactorial, involving:
• Immune System Dysfunction: Abnormalities in immune function.
• Adrenal System Dysfunction: Issues with the body’s stress response system.
• Genetic Factors: Certain genetic markers may increase susceptibility.
• History of Infections: Some cases follow viral infections.
Genetic predisposition: Some studies suggest a genetic component, with specific genetic markers potentially increasing susceptibility to CFS/ME (CDC, 2023). Family history of similar conditions may indicate a hereditary aspect (CDC, 2023).
Infections: Many cases of CFS/ME begin after a viral infection, such as Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6), or enteroviruses (CDC, 2023). Bacterial infections, such as Lyme disease, have also been implicated (CDC, 2023).
Immune system dysfunction: Abnormalities in immune function, including chronic immune activation and altered cytokine profiles, have been observed in CFS/ME patients (CDC, 2023). Some researchers propose that an overactive immune response to an infection could trigger the condition (CDC, 2023).
Endocrine system dysfunction: In CFS/ME, dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, which controls stress response and hormone production, has been noted (CDC, 2023). This dysregulation may contribute to symptoms such as fatigue and cognitive impairment (CDC, 2023).
Psychological and social factors: Psychological stress and trauma, particularly in childhood, have been associated with the development of CFS/ME (CDC, 2023). Social and environmental stressors may exacerbate symptoms.
Pathogenesis: The pathogenesis of CFS/ME involves several proposed mechanisms that contribute to the development and persistence of symptoms:
• Neuroinflammation: Inflammation of the central nervous system (CNS) has been suggested as a critical factor in CFS/ME (CDC, 2023). Neuroinflammation may result from chronic immune activation and contribute to cognitive dysfunction and fatigue (CDC, 2023).
• Mitochondrial Dysfunction: Impaired mitochondrial function, leading to reduced energy production, has been observed in CFS/ME patients. This dysfunction may explain the condition’s profound fatigue and exercise intolerance.
• Oxidative Stress: Increased oxidative stress and reduced antioxidant defences have been reported in CFS/ME. Oxidative stress can damage cells and tissues, affecting the overall symptomatology.
• Autonomic Nervous System Dysfunction: Dysregulation of the autonomic nervous system (ANS), which controls involuntary bodily functions, has been implicated in CFS/ME. Symptoms such as orthostatic intolerance, dizziness, and heart rate variability may be linked to ANS dysfunction.
• Gut Microbiome Alterations: Changes in the gut microbiome, including dysbiosis (imbalance of gut bacteria), have been associated with CFS/ME. Gut microbiome alterations may influence immune function and inflammation, contributing to symptoms.
Misconceptions about Chronic Fatigue Syndrome and ME
There are several common misconceptions about chronic fatigue syndrome (CFS) / Myalgia Encephalomyelitis (ME). Here are some of the most prevalent ones:
“CFS/ME is just being tired all the time.”
Fact: While fatigue is a significant symptom, CFS/ ME involves much more than feeling tired. The fatigue experienced is profound and not relieved by rest. It is often accompanied by other symptoms such as post- exertional malaise (PEM), unrefreshing sleep, cognitive impairments, muscle, and joint pain, and more (CDC, 2023).
“CFS/ME is a psychological disorder.”
Fact: CFS/ME is a complex, multi-system illness with documented abnormalities in the immune, endocrine, and nervous systems. It is not a psychiatric condition, although the chronic nature of the illness can lead to secondary psychological issues (CDC, 2023).
“Exercise and cognitive behavioural therapy (CBT) can cure CFS/ME.”
Fact: While some studies, like the PACE trial, suggested benefits from graded exercise therapy (GET) and CBT, many patients report that these treatments can worsen their symptoms. The effectiveness of these therapies is highly debated, and they are not considered cures (CDC, 2023).
“CFS/ME only affects middle-aged women.”
Fact: CFS/ME can affect individuals of all ages, genders, and socioeconomic backgrounds. The misconception that it primarily affects middle-aged women may stem from biased patient populations in certain studies (CDC, 2023).
“Children do not get CFS/ME.”
Fact: Children and adolescents can also develop CFS/ME.
There have been documented outbreaks among children, and the illness can significantly impact their development and education (CDC, 2023).
“CFS/ME is difficult to diagnose.”
Fact: While diagnosing CFS/ME can be challenging due to its complex nature and overlapping symptoms with other conditions, experienced clinicians can diagnose it through detailed patient history and exclusion of other conditions (CDC, 2023).
“People with CFS/ME are just lazy or lack motivation.”
Fact: This is a harmful stereotype. People with CFS/ME often want to be active and productive but are physically unable to due to the severity of their symptoms. The illness can be debilitating and significantly impact daily functioning (CDC, 2023).
Understanding these misconceptions is crucial for providing better support and care for individuals with CFS/ ME.
Diagnostic Criteria
The current diagnostic criteria for Chronic Fatigue Syndrome (CFS), also known as Myalgia Encephalomyelitis (ME), are based on guidelines from the Institute of Medicine (IOM), now the National Academy of Medicine (NAM), published in 2015. These criteria aim to facilitate timely diagnosis and improve understanding of the illness. Here are the key components:
IOM 2015 Diagnostic Criteria
Required symptoms
1. Substantial reduction or impairment in pre-illness levels of activity:
• Significant reduction in the ability to engage in occupational, educational, social, or personal activities.
• This impairment must last for more than six months and be accompanied by fatigue that is:
• Often profound
• Of new onset (not lifelong)
• Not the result of ongoing excessive exertion
• Not alleviated by rest
2. Post-Exertional Malaise (PEM):
• Worsening of symptoms following physical, mental, or emotional exertion that would not have caused a problem before the illness.
• PEM often leads to a relapse that can last days, weeks, or even Symptoms typically worsen 12 to 48 hours after the activity and can last for days or weeks.
3. Unrefreshing sleep:
• Patients do not feel refreshed after a whole night’s sleep despite the absence of specific objective sleep alterations.
Additional Symptoms
To be diagnosed with ME/CFS, patients must have at least one of the following symptoms in addition to the three required symptoms above:
1. Cognitive impairment:
• Problems with thinking, memory, executive function, and information processing.
• These issues can be exacerbated by exertion, effort, prolonged upright posture, stress, or time pressure.
2. Orthostatic intolerance:
• Worsening of symptoms upon assuming and maintaining an upright posture.
• Symptoms include light-headedness, fainting, increased fatigue, cognitive worsening, headaches, or nausea, which improve (though not necessarily fully resolve) with lying down.
Frequency and Severity
The frequency and severity of these symptoms need to be evaluated. Patients should have symptoms at least half the time with moderate, substantial, or severe intensity for diagnosis.
Other Common Symptoms
While not required for diagnosis, many people with ME/
CFS also experience:
• Muscle pain
• Joint pain without swelling or redness.
• Headaches of a new type, pattern, or severity
• Swollen or tender lymph nodes in the neck or armpit
• Frequent or recurring sore throat.
• Chills and night sweats
• Visual disturbances
• Sensitivity to light and sound
• Nausea
• Allergies or sensitivities to foods, odours, chemicals, or medications
Exclusion of other conditions
It is crucial to rule out other medical and psychiatric conditions that could explain the symptoms before diagnosing ME/CFS.
These criteria help healthcare professionals diagnose ME/CFS more accurately and provide appropriate patient care and support.
Severity classification
The National Institute for Health and Care Excellence (NICE) classifies the severity of CFS/ME as follows:
• Mild: Mobility is preserved with some limitations in self-care.
• Moderate: Mobility is restricted with significant limitations in self-care.
• Severe: Mobility and function are severely restricted with cognitive dysfunction.
• Very Severe: Completely dependent on others for all aspects of daily living.
Comprehensive Management Principles: An Update
The medical management of chronic fatigue syndrome (CFS) / Myalgia Encephalomyelitis (ME) focuses on alleviating symptoms, improving quality of life, and enhancing functional capacity. Here are the critical components of current medical management strategies:
3. Symptom-Specific Medications
• Pain Management: Over-the-counter pain relievers such as ibuprofen and acetaminophen can help manage muscle and joint pain. In some cases, prescription medications like low-dose tricyclic antidepressants (e.g., amitriptyline) are used to alleviate pain and improve sleep (NHS, 2024).
• Sleep Aids: If sleep hygiene strategies are insufficient, medications to improve sleep quality may be prescribed. These can include low-dose antidepressants or other sleep-inducing medications (NHS, 2024).
• Antidepressants: These can be useful for managing pain, sleep disturbances, and co-existing Commonly used antidepressants include amitriptyline and doxepin (NHS, 2024).
4. Cognitive Behavioural Therapy (CBT)
• CBT for CFS/ME: This therapy helps patients manage the psychological impact of the illness, develop coping strategies, and address unhelpful thoughts or behaviours that may contribute to symptom persistence. It is tailored to the individual’s symptoms and experiences (NHS, 2024).
5. Graded Exercise Therapy (GET)

Chronic Fatigue Syndrome (CFS), or Myalgia Encephalomyelitis (ME), is a complex and debilitating condition characterized by profound fatigue that is not alleviated by rest and exacerbated by physical or mental activity. This condition significantly impairs the ability to perform daily activities and can reduce quality of life. The fatigue experienced by individuals with CFS/ME is often accompanied by a range of other symptoms, including cognitive impairments, unrefreshing sleep, and post- exertional malaise (PEM). The aetiology of CFS/ME remains unclear, but it is believed to be multifactorial, involving genetic predisposition, infections, immune system dysfunction, and endocrine abnormalities. The pathogenesis of the condition includes neuroinflammation, mitochondrial dysfunction, oxidative stress, autonomic nervous system dysregulation, and gut microbiome alterations. These factors contribute to the diverse and persistent symptoms experienced by patients. Diagnosing CFS/ME can be challenging due to the overlap of symptoms with other conditions. The current diagnostic criteria, such as those from the Institute of Medicine (IOM), emphasize the presence of severe fatigue lasting more than six months, post-exertional malaise, unrefreshing sleep, and cognitive impairment or orthostatic intolerance. It is crucial to rule out other medical and psychiatric conditions that could explain the symptoms before diagnosing CFS/ME.
Effective management of CFS/ME requires a comprehensive and multidisciplinary approach. Current evidence-based treatments focus on symptom management, including pacing and energy management, cognitive behavioural therapy (CBT), and graded exercise therapy (GET). These interventions aim to improve functional capacity and quality of life while minimizing the risk of symptom exacerbation. Symptom-specific medications, dietary and nutritional support, sleep hygiene, stress management, and psychological support are also integral components of the treatment plan.
Emerging therapies, such as neuromodulation techniques and ongoing pharmacological research, offer hope for more effective treatments in the future. These innovative approaches are being explored to better understand the underlying mechanisms of CFS/ME and to develop targeted therapies that can relieve patients. Support systems, including counselling, support groups, and education for family and friends, play a crucial role in managing CFS/ME. These resources help patients cope with the illness’s emotional and psychological impact and provide a network of understanding and support. Ongoing research is essential to further elucidate the aetiology and pathogenesis of CFS/ME, improve diagnostic criteria, and develop more effective treatments. Continued efforts in this field aim to enhance patient outcomes and provide better support for those affected by this challenging condition.
Chronic Fatigue Syndrome / Myalgia Encephalomyelitis is a complex and multifaceted condition that requires a holistic and patient-centred approach to management. By combining evidence-based treatments, emerging therapies, and robust support systems, healthcare providers can help improve the quality of life for individuals living with CFS/ME. Ongoing research and increased awareness are vital to advancing our understanding and treatment of this debilitating illness.
CFS/ME can profoundly impact a person’s quality of life, affecting their ability to work, study, and engage in social activities. The condition can fluctuate, with periods of relative improvement and worsening symptoms. Understanding CFS/ME requires a comprehensive approach, considering both the physical and psychological aspects of the illness. Ongoing research aims to better understand the underlying mechanisms and develop more effective treatments.
