Depression and chronic fatigue in the patient with chronic pain.
Covington, E C · Primary care · 1991
Quick Summary
This study explores how chronic pain, fatigue, and depression often occur together in patients. The authors suggest that these three conditions share common causes and may influence each other. Treatment works best when doctors address each problem separately using a combination of physical rehabilitation, education, medications, and counseling.
Why It Matters
This study is relevant to ME/CFS patients because it acknowledges that fatigue, pain, and mood disturbance frequently co-occur and may share underlying mechanisms. Understanding these interconnections may help clinicians and patients recognize that treating depression as a separate component could improve overall outcomes and provide hope for recovery.
Observed Findings
- Chronic benign pain is commonly associated with chronic fatigue and depression
- Depression and chronic fatigue syndrome frequently co-occur and often include pain
- Psychologic factors are prominent in these conditions
- Neurobiologic factors may be shared among pain, fatigue, and depression
- Depression may be associated with better prognosis due to its treatability
Inferred Conclusions
- Integrated management addressing pain, fatigue, and depression as separate but related components is more effective than treating them in isolation
- The presence of depression in chronic pain and fatigue patients may be prognostically favorable because depression responds to treatment
- Shared neurobiologic mechanisms likely underlie the co-occurrence of chronic pain, chronic fatigue, and depression
Remaining Questions
- What are the specific neurobiologic mechanisms linking pain, fatigue, and depression?
- Does treating depression improve fatigue and pain outcomes in ME/CFS patients?
- How should the relative emphasis on physical rehabilitation, medication, and counseling be individualized for different patients?
What This Study Does Not Prove
This review does not establish causation—it does not prove that depression causes fatigue or pain, or vice versa. It does not present original empirical data or clinical trials demonstrating efficacy of the proposed management approach. The study also does not differentiate between depression as a primary condition versus depression secondary to living with chronic illness.

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 →
