Antidepressants and cognitive-behavioral therapy for symptom syndromes.
Jackson, Jeffrey L, O'Malley, Patrick G, Kroenke, Kurt · CNS spectrums · 2006 · DOI
Quick Summary
This review looked at research on whether antidepressant medications and talking therapy (cognitive-behavioral therapy or CBT) help with long-lasting physical symptoms like pain and fatigue. The researchers examined studies on 11 different conditions, including chronic fatigue syndrome. They found that CBT was the most consistently helpful treatment, while antidepressants showed mixed results depending on the specific condition.
Why It Matters
This review provides a systematic examination of two commonly prescribed treatments for ME/CFS and related somatic syndromes. For ME/CFS patients considering these treatments, it offers evidence-based context about what research does and does not support. The review's emphasis on CBT effectiveness and variable antidepressant outcomes is relevant to clinical decision-making.
Observed Findings
- Cognitive-behavioral therapy demonstrated the most consistent evidence of effectiveness across the 11 somatic syndromes reviewed.
- Antidepressant medications showed heterogeneous efficacy across the different somatic symptom syndromes studied.
- Theoretical rationale exists for antidepressants with balanced norepinephrine and serotonin effects, but head-to-head comparisons are lacking.
- Evidence quality and quantity varied substantially across the 11 conditions, with some syndromes having robust data and others having minimal research.
Inferred Conclusions
- Cognitive-behavioral therapy represents the most evidence-supported psychological treatment for somatic symptom syndromes.
- Antidepressant efficacy may depend on syndrome-specific pathophysiology and individual patient characteristics.
- Additional high-quality randomized controlled trials are needed to clarify antidepressant effectiveness for many somatic syndromes, particularly those with limited evidence.
Remaining Questions
- What are the mechanisms by which antidepressants may reduce symptoms in specific somatic syndromes like ME/CFS?
- Do balanced monoamine reuptake inhibitors outperform selective serotonin reuptake inhibitors in effectiveness for these conditions?
What This Study Does Not Prove
This review does not establish that antidepressants are effective specifically for ME/CFS, as the abstract indicates data were 'scanty' for many syndromes. The review cannot prove causation or mechanisms of action—it only surveys existing trial evidence. It does not address whether treatment effects in these conditions are specific to symptom reduction or reflect treatment of comorbid depression/anxiety.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
