Mixed Deck — All CFS Topics Flashcards

Which type of pain is most commonly reported by CFS patients?

Answer: Widespread muscle pain (myalgia) and joint pain (arthralgia)

CFS patients frequently experience widespread muscle pain (myalgia) and joint pain (arthralgia) without swelling or redness.

What is the 'Millions Missing' campaign associated with ME/CFS advocacy?

Answer: A global campaign highlighting that millions with ME/CFS are missing from normal life due to their illness

The 'Millions Missing' campaign is a global advocacy campaign highlighting that millions of people with ME/CFS are effectively 'missing' from normal life — work, school, and social activities — due to their severe illness.

What is the 'low-dose naltrexone' (LDN) interest in the context of CFS comorbidities?

Answer: LDN is used off-label for CFS and related conditions based on its potential anti-inflammatory and immunomodulatory effects

Low-dose naltrexone is used off-label for CFS and related conditions due to its potential immunomodulatory and anti-neuroinflammatory effects, though more research is needed.

What is the significance of the 2-day CPET (cardiopulmonary exercise test) in CFS research?

Answer: It demonstrates objective aerobic dysfunction and PEM on the second day of testing

The 2-day CPET demonstrates objective evidence of PEM by showing significantly impaired aerobic capacity on the second test day compared to the first, which does not occur in healthy people.

What does 'post-infectious fatigue syndrome' (PIFS) describe in relation to CFS?

Answer: A subset of CFS that develops following an acute infection

Post-infectious fatigue syndrome describes cases where CFS develops following an acute infection, representing a significant subset of CFS patients.

Why is obtaining disability accommodations challenging for many CFS patients?

Answer: Lack of objective biomarkers and physician skepticism make it difficult to document and prove disability

The lack of widely accepted objective biomarkers for CFS, combined with physician skepticism, makes it challenging for many patients to document their disability and receive appropriate accommodations.

What infectious trigger has been most commonly associated with the onset of CFS?

Answer: Epstein-Barr virus (EBV) and other viral infections

CFS frequently begins after a viral illness, with Epstein-Barr virus among the most studied triggers, though many other infections can also precipitate it.

What does the historical term 'neurasthenia' refer to in the context of ME/CFS history?

Answer: A 19th-century diagnosis of nervous exhaustion, sometimes considered a historical predecessor to CFS

Neurasthenia, a 19th-century diagnosis describing nervous exhaustion with fatigue and multiple symptoms, is considered by some historians to be a historical predecessor to modern ME/CFS.

What is 'pacing' in the context of CFS daily living?

Answer: Managing activity levels to avoid exceeding one's energy envelope

Pacing involves carefully managing physical and mental activity to stay within one's energy limits and avoid triggering post-exertional malaise.

Quantitative sensory testing (QST) in CFS research is used to measure:

Answer: Sensory thresholds and pain sensitivity

Quantitative sensory testing measures sensory thresholds and pain sensitivity to standardized stimuli, helping identify central sensitization and sensory processing abnormalities in CFS.

What is the importance of having a healthcare team familiar with CFS for self-care planning?

Answer: CFS-knowledgeable providers can create personalized pacing plans, avoid harmful recommendations, and address comorbidities appropriately

Having CFS-knowledgeable healthcare providers ensures that self-care plans are appropriate, harmful recommendations like aggressive exercise are avoided, and comorbidities are properly managed.

What is the 'MECFS Clinician Coalition' in the United States?

Answer: A network of clinicians working to improve CFS diagnosis and care standards

The ME/CFS Clinician Coalition is a network of US clinicians dedicated to improving the quality of ME/CFS diagnosis and clinical care through education and resource sharing.

Which body system is believed to play a central role in CFS pathophysiology according to current research?

Answer: Immune system dysregulation

Current research strongly implicates immune system dysregulation, including abnormal cytokine profiles and immune activation, in the pathophysiology of CFS.

What role does sleep hygiene play in the management of Chronic Fatigue Syndrome (CFS)?

Answer: It helps improve sleep quality and overall well-being

Explanation: Sleep hygiene plays a crucial role in the management of Chronic Fatigue Syndrome (CFS). By adopting good sleep hygiene practices such as maintaining a consistent sleep schedule, creating a comfortable sleep environment, limiting caffeine and screen time before bed, and practicing relaxation techniques, individuals with CFS can improve their sleep quality. Better sleep quality contributes to overall well-being and can help alleviate symptoms associated with CFS, such as fatigue and cognitive difficulties.

What is the 'Solve ME/CFS Initiative' known for?

Answer: Being a US non-profit focused on funding research and developing a biobank for ME/CFS

The Solve ME/CFS Initiative is a US non-profit that funds research and maintains the Ramsay Biobank, a collection of patient samples supporting CFS biological research.

What does '#MEAction' represent in the CFS community?

Answer: A global patient-led advocacy network that campaigns for ME/CFS research and recognition

#MEAction is a global, patient-led advocacy network that runs campaigns, provides patient support, and advocates for increased ME/CFS research funding and recognition.

What is the 'energy envelope' theory in CFS management?

Answer: Staying within one's available energy capacity to prevent PEM

The energy envelope theory suggests CFS patients should stay within their available energy capacity to minimize symptom exacerbation and crashes.

Autonomic nervous system dysfunction in CFS most commonly presents as:

Answer: Orthostatic intolerance with symptoms worsening upon standing

Orthostatic intolerance—where symptoms worsen when standing upright—is the most common manifestation of autonomic dysfunction in CFS, often accompanied by heart rate changes.

What is 'mast cell activation syndrome' (MCAS) and its relationship to CFS?

Answer: A condition of inappropriate mast cell activation that may co-occur with CFS, contributing to multi-system symptoms

MCAS involves inappropriate activation of mast cells causing multi-system symptoms; it may co-occur with CFS and potentially contribute to some of the overlapping symptom burden.

When was the first documented ME outbreak officially recognized?

Answer: 1934, Los Angeles County Hospital

One of the earliest documented ME outbreaks occurred in 1934 at Los Angeles County Hospital, affecting medical staff.
