Martin-Du-Pan, R · Revue medicale de la Suisse romande · 1990
This 1990 review article examines the relationships between chronic fatigue syndrome (ME/CFS), fibromyalgia, and depression. The author discusses how these three conditions sometimes occur together and explores whether they share common features or causes. The paper helps clarify how ME/CFS and fibromyalgia are distinct from depression, even though all three can cause fatigue and other overlapping symptoms.
This study is important because distinguishing ME/CFS from depression and fibromyalgia has significant clinical implications for diagnosis and treatment. Clarifying these relationships helps prevent misdiagnosis and ensures patients receive appropriate, condition-specific care rather than inappropriate psychiatric treatment alone.
This review does not provide new empirical evidence about disease mechanisms, prevalence, or treatment efficacy. It cannot establish causation or definitively prove that ME/CFS, fibromyalgia, and depression are entirely separate conditions—it addresses conceptual and clinical distinctions based on existing knowledge. The 1990 publication date means it predates modern biomarker research and contemporary understanding of these conditions.
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 →
