[Symptomatic and concurrent depressions].
Terra, J L · La Revue du praticien · 1999
Quick Summary
This paper explains that when people have depression, they often also have other mental health or physical health problems at the same time. Examples include anxiety disorders, alcohol use problems, eating disorders, and medical conditions like heart disease, cancer, and chronic fatigue syndrome. The authors provide guidance to help doctors decide which condition to treat first when someone has multiple problems occurring together.
Why It Matters
ME/CFS patients frequently experience comorbid depression, and understanding how to manage multiple concurrent conditions is essential for appropriate clinical care. This guideline addresses the practical challenge of treatment prioritization in patients with both ME/CFS and depressive symptoms, which is a common clinical scenario.
Observed Findings
- Depression frequently occurs alongside other psychiatric disorders including anxiety, alcoholism, and eating disorders
- Depression is associated with multiple general medical conditions including cancer, coronary artery disease, endocrine disorders, dementia, stroke, and chronic fatigue syndrome
- Clinicians need systematic guidance for treatment decisions when depression and other disorders coexist
Inferred Conclusions
- Comorbidity and symptomatic co-occurrence are important concepts for understanding depression in clinical practice
- When multiple psychiatric or medical conditions occur together with depression, a prioritized treatment approach is necessary
- A decision algorithm can guide clinicians in selecting which condition to address first or concurrently
Remaining Questions
- What is the optimal treatment sequencing when depression and ME/CFS occur together?
- How does treating depression affect ME/CFS symptom severity and function?
- What are the mechanisms underlying the association between depression and ME/CFS?
- How effective is the proposed decision algorithm in clinical practice?
What This Study Does Not Prove
This guideline does not establish whether depression causes ME/CFS or vice versa, nor does it provide empirical evidence about the prevalence of depression in ME/CFS populations. It does not prove that treating depression will improve ME/CFS outcomes or address ME/CFS-specific pathophysiology.

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 →
