From the Guidelines

Chronic Fatigue Syndrome (CFS) treatment should prioritize cognitive-behavioral therapy, as it has the greatest evidence for improving health function, health-related quality of life, or physical function, as shown in a meta-analysis of 29 studies 1. The development mechanisms of CFS are complex and involve immune system dysfunction, neurological abnormalities, hormonal imbalances, and energy metabolism disruptions. Treatment options for CFS focus on symptom management rather than cure, and a multidisciplinary approach is recommended. Key components of treatment include:

  • Pacing activities to avoid post-exertional malaise
  • Graded exercise therapy starting with very gentle movement
  • Cognitive behavioral therapy to develop coping strategies
  • Medications such as low-dose antidepressants, NSAIDs, and sometimes modafinil for severe fatigue
  • Sleep hygiene practices, including consistent sleep schedules and avoiding caffeine and electronics before bed
  • Nutritional support focusing on anti-inflammatory foods, regular small meals, and staying well-hydrated
  • Supplements like CoQ10, magnesium, and vitamin B12, though evidence is limited 1. It is essential to note that stimulants should not be offered for treatment of fatigue in patients with CFS, as recommended against in the 2021 US Department of Veterans Affairs and US Department of Defense clinical practice guideline 1. Management of CFS requires patience and personalization, as treatments that help one person may not help another, and recovery often involves cycles of improvement and relapse. Recent studies have also explored other treatment options, including intravenous immunoglobulin, low-dose naltrexone, and antivirals, but more research is needed to confirm their effectiveness 1.

From the Research

Development Mechanisms of Chronic Fatigue Syndrome (CFS)

  • The exact development mechanisms of CFS are not fully understood, but it is believed to involve a combination of factors, including immune dysregulation and mitochondrial dysfunction 2.
  • Viral infections, such as COVID-19, may trigger the onset of CFS symptoms 2.
  • Genetic, immune, cognitive, sleep, metabolic, and biochemical abnormalities may also contribute to the development of CFS 3.

Treatment Options for CFS

  • Mind-body interventions (MBIs), such as mindfulness-based stress reduction, cognitive-behavioral therapy, and relaxation, have been shown to improve fatigue severity, anxiety, and depression in patients with CFS 4.
  • Cognitive behavioral therapy (CBT) and graded exercise therapy (GET) are evidence-based treatments for CFS, but their effectiveness and safety are still debated 5, 6.
  • Pacing, which involves balancing activity with rest, is a coping strategy that can help patients manage their symptoms and improve functionality 5, 3.
  • Symptomatic treatment, such as managing pain, sleep, and cognitive dysfunction, is also an important aspect of CFS management 3.
  • The most effective treatment approach may involve a combination of these strategies, tailored to the individual patient's needs and preferences 6, 3.

Challenges and Limitations in CFS Treatment

  • The heterogeneity of CFS symptoms and the lack of standardized diagnostic criteria can make it challenging to develop effective treatments 4, 2.
  • Small sample sizes and high risk of bias in clinical studies can limit the generalizability of findings 4.
  • Further research is needed to advance our understanding of CFS and to develop more effective treatments 4, 2, 6.
