Chronic fatigue syndrome--a diagnosis for consideration.
Portwood, M F · The Nurse practitioner · 1988
Quick Summary
This article helps doctors recognize ME/CFS by describing its many symptoms, which can range from mild tiredness to severe disability. Patients often report feeling exhausted, achy, and unable to concentrate, yet standard medical tests often appear normal. The article emphasizes that doctors should take these symptoms seriously and help patients manage their condition, even though there is currently no cure.
Why It Matters
This article was important in 1988 for raising clinical awareness of ME/CFS among healthcare providers who might otherwise dismiss or misdiagnose patients. It emphasizes the legitimacy of the illness and the healthcare provider's role in recognizing this confusing disorder, which was particularly valuable during a period when ME/CFS lacked widespread clinical recognition.
Observed Findings
ME/CFS presents with multiple varied symptoms including fatigue, malaise, myalgias, difficulty concentrating, headaches, and sore throat.
Patient-reported symptoms often appear disproportionate to objective physical examination findings.
Physical examination findings may be completely normal despite significant symptom burden.
ME/CFS can range from mild to completely disabling in severity.
Patients frequently present with recurring non-related symptoms without a specific diagnosis.
Inferred Conclusions
Healthcare providers should recognize ME/CFS as a legitimate diagnosis in patients with recurring symptoms and normal physical findings.
Clinical management should focus on symptomatic therapy rather than curative approaches.
The healthcare provider's role includes helping both patients and families cope with the multifaceted effects of this chronic illness.
Clinical awareness is necessary to prevent misdiagnosis and inappropriate investigations.
Remaining Questions
What are the underlying biological mechanisms causing ME/CFS symptoms?
What This Study Does Not Prove
This review does not establish the cause of ME/CFS, provide treatment efficacy data, or offer diagnostic criteria validated through systematic research. It does not prove why symptoms appear disproportionate to physical findings, nor does it define which symptomatic treatments are most effective. As a clinical opinion piece rather than an empirical study, it cannot establish causation or quantify disease burden.
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 →
