What are the management strategies for chronic fatigue syndrome?

Management of Chronic Fatigue Syndrome

Begin with cognitive-behavioral therapy (CBT) and graded exercise therapy as first-line interventions, as these are the only treatments with proven efficacy for improving fatigue, functional capacity, and quality of life in chronic fatigue syndrome. 1, 2, 3

Initial Diagnostic Approach

Establish the Diagnosis

• Confirm severe fatigue lasting longer than 6 months that is not relieved by rest and significantly interferes with daily functioning 3
• Document at least 4 of 8 required physical symptoms: postexertional malaise, unrefreshing sleep, impaired memory/concentration, muscle pain, polyarthralgia, sore throat, tender lymph nodes, or new headaches 3
• Recognize this is a diagnosis of exclusion—no definitive laboratory test or physical finding confirms CFS 4, 3

Mandatory Exclusion of Alternative Diagnoses

• Screen for depression and anxiety using validated tools, as these commonly overlap with CFS and require specific treatment 1, 2
• Evaluate for sleep disorders including sleep apnea, as sleep disturbance perpetuates fatigue 2, 5
• Assess for hypothyroidism, anemia, and other metabolic disorders through basic laboratory testing 4
• Rule out neuropsychiatric disorders and somatoform disorders that can mimic CFS 5

Build Therapeutic Alliance

• Establish mutual trust and collaboration as the foundation of management—this is the most important first step 2
• Provide a positive explanation distinguishing predisposing factors (lifestyle, work stress), triggering factors (viral infection, life events), and perpetuating factors (cerebral dysfunction, sleep disorder, depression, inconsistent activity patterns) 2

Evidence-Based Treatment Algorithm

Step 1: Implement Nonpharmacologic Interventions (Category 1 Evidence)

Cognitive-Behavioral Therapy (CBT)

• Offer structured CBT tailored to address thoughts, feelings, and behaviors related to fatigue 1
• CBT demonstrates moderate improvements in fatigue severity, distress, cognitive symptoms, and mental health functioning 1
• Target catastrophic misinterpretations of symptoms and promote problem-solving for current life difficulties 2
• Consider web-based CBT as an effective alternative when in-person therapy is unavailable 6

Graded Exercise Therapy

• Prescribe gradual return to physical activity starting with low intensity (even 10-15 minutes of walking initially) 6
• Progress to moderate aerobic exercise 3-5 times weekly, gradually increasing based on tolerance 6
• Emphasize that exercise improves strength, energy, fitness, and reduces anxiety and depression 7, 1
• Include yoga or tai chi as alternatives, which show significant improvements in physical functioning, quality of life, pain, fatigue, sleep quality, and mood 1

Activity and Sleep Management

• Promote a consistent pattern of activity, rest, and sleep—this is the most important starting point 2
• Implement energy conservation strategies: prioritize activities, pace tasks, delegate nonessential activities, and schedule activities during peak energy periods 7
• Apply cognitive-behavioral therapy for insomnia (CBT-I) if sleep disturbance is identified, as this is more effective than pharmacologic sleep aids 6
• Limit daytime naps to less than one hour to avoid disturbing nighttime sleep 7

Mindfulness-Based Interventions

• Offer mindfulness-based stress reduction programs, which show moderate effect sizes for enhancing quality of life 1
• These address cognitive and emotional factors contributing to fatigue 6

Step 2: Address Comorbid Conditions

Treat Depression When Present

• Initiate SSRIs or SNRIs if depression is identified—this is a Category 1 recommendation for fatigue management 6
• Bupropion may be considered based on favorable results in open-label trials for CFS-related fatigue 1
• Avoid paroxetine, as it has not shown benefit for CFS 1

Manage Pain

• Consider SNRIs for pain management and improved functional status 1
• Offer pregabalin for pain management in patients with CFS 1
• Avoid opioid medications for CFS-related pain 1
• Avoid NSAIDs for chronic pain related to CFS 1

Complementary Approaches

• Consider manual acupuncture as part of management, with evidence supporting effectiveness 1
• Offer emotion-focused therapy, which has shown benefits for patients with CFS 1

Step 3: Pharmacologic Options for Persistent Symptoms

Limited Role of Medications

• Recognize that no pharmacologic therapies have proven effective as primary treatment for CFS 3
• Reserve medications for symptomatic management of specific issues (sleep disturbances, pain, depression) 4, 5
• Modafinil may be considered for individuals with severe fatigue, though overall trial results were negative—use with caution 1

Avoid Ineffective Treatments

• Do not use corticosteroids, antivirals, or antibiotics—they show no benefit 1
• Avoid stimulants for fatigue symptoms 1
• Do not use progestational steroids—they have not demonstrated benefit 1
• Do not use mifepristone for CFS 1

Step 4: Ongoing Monitoring and Multidisciplinary Care

Regular Assessment

• Monitor fatigue severity at every clinical encounter using a 0-10 numeric rating scale 6, 1
• Assess impact on daily activities and functional capacity, as similar fatigue scores produce vastly different disability levels 6
• Periodically discuss access to psychoeducational interventions based on patient needs 1

Specialist Referrals When Needed

• Refer to mental health professionals for implementing evidence-based CBT and mindfulness interventions 1
• Involve physical therapists for addressing physical deconditioning and activity limitations 1
• Consider rheumatology consultation when CFS presents with significant musculoskeletal symptoms 1
• Refer patients with unresolved fatigue despite comprehensive management to appropriate specialists 6

Critical Pitfalls to Avoid

• Do not assume fatigue will resolve spontaneously—it requires active management even when no underlying disease is found 6
• Do not skip nonpharmacologic interventions (exercise and CBT) in favor of medications, as they have the strongest evidence 6, 3
• Do not focus exclusively on either physical or psychological aspects—CFS requires addressing both biological and psychosocial factors 1
• Do not prescribe medications without first implementing CBT and graded exercise, as these are the only interventions with proven efficacy 2, 3
• Do not tell patients to simply "rest more"—inconsistent activity patterns perpetuate the illness 2
