This review examines what ME/CFS is and how it works in the body. The research shows that ME/CFS is a real condition separate from depression or anxiety, though the official way doctors diagnose it may need updating. Scientists have found signs that the nervous system, immune system, and genetics all play a role, but they still don't fully understand how these pieces fit together.
This review is important because it validates ME/CFS as a distinct medical condition rather than a psychiatric disorder, which helps combat stigma and supports diagnostic legitimacy. By synthesizing evidence across phenomenology and pathophysiology, it provides a framework for understanding the biological mechanisms underlying ME/CFS and identifies critical gaps needing future research.
This review does not establish whether the observed pathophysiologic changes (serotonergic state, HPA axis changes, immune alterations) cause ME/CFS or result from it—a crucial distinction for treatment development. It also does not identify specific genes involved or clarify the relative importance of genetic versus environmental factors. The review cannot prove which case definition is optimal, only that improvements are needed.
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 →
