This article reviews what we currently know about ME/CFS, a serious illness marked by extreme tiredness, sleep problems, difficulty thinking clearly, and difficulty standing up without symptoms getting worse. A key feature is post-exertional malaise—when patients feel much worse after physical or mental activity—which means people with ME/CFS need to carefully manage their activity levels. The article summarizes current approaches to diagnosis and treatment, as well as recent scientific discoveries about what happens in the body during this disease.
This review is important because it consolidates current understanding of ME/CFS across diagnostic, therapeutic, and biological domains in one accessible reference. For patients, it validates post-exertional malaise as a core feature requiring specific management strategies. For researchers and clinicians, it provides a contemporary synthesis of how biological research may inform clinical practice in an understudied disease.
As a narrative review, this article does not present original research data or establish causation for any biological mechanisms in ME/CFS. It does not prove the efficacy of any particular treatment—it summarizes existing approaches without meta-analysis or controlled comparison. The article's conclusions reflect the author's interpretation of the literature and may not represent consensus across all ME/CFS research.
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 →
