Subjective health complaints, sensitization, and sustained cognitive activation (stress).
Eriksen, H R, Ursin, H · Journal of psychosomatic research · 2004 · DOI
Quick Summary
This review suggests that common symptoms like pain, tiredness, sleep problems, and digestive issues in conditions like ME/CFS may occur when the body's normal sensing system becomes overly sensitive. Rather than being caused by hidden disease, these symptoms may develop when people experience sustained stress and feel helpless, causing the nervous system to amplify normal bodily signals until they become unbearable.
Why It Matters
This theoretical framework offers an alternative explanation for why ME/CFS patients experience severe symptoms without proportionate objective medical findings, and suggests that understanding sensitization mechanisms could inform treatment approaches targeting attention, coping, and arousal regulation.
Observed Findings
- Subjective health complaints are common in the general population but become disabling in some individuals.
- Common complaints include musculoskeletal pain, gastrointestinal symptoms, fatigue, sleep disturbance, and mood changes.
- These conditions occur across multiple diagnostic labels including ME/CFS, fibromyalgia, burnout, and multiple chemical sensitivity.
- Affected individuals often show low coping capacity and high levels of helplessness and hopelessness.
Inferred Conclusions
- Neural sensitization maintained by sustained attention and arousal may underlie subjective health complaints without somatic findings.
- Psychological factors including low coping and high hopelessness may drive intolerance of normal physiological sensations.
- The term 'subjective health complaints' is more neutral and accurate than 'unexplained medical symptoms' for these conditions.
Remaining Questions
- What specific neurobiological mechanisms underlie the sensitization process in these conditions?
- How do individual differences in coping capacity and psychological resilience mechanistically relate to symptom severity?
- Can interventions targeting attention, arousal, and coping capacity reverse sensitization in established ME/CFS?
What This Study Does Not Prove
This review does not prove that ME/CFS is purely psychological or that physical pathology does not exist. It does not establish causation between stress and symptom development, nor does it rule out that some cases may have underlying organic disease. The proposed mechanism is theoretical rather than empirically validated in this paper.

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 →
