This review suggests that ME/CFS may develop when the body has trouble controlling infections early on, leading to long-term inflammation in the brain. The authors propose that this inflammatory process—involving both the immune system and the nervous system—could explain many ME/CFS symptoms and why more women are affected than men. They also suggest that anti-inflammatory treatments targeting a protein called TNF might help patients.
This paper provides a potential unifying mechanism explaining multiple ME/CFS symptoms and the female predominance in the disease, which could guide future research directions. If the inflammatory model is correct, it could justify clinical trials of anti-inflammatory treatments that have been difficult to justify previously in ME/CFS.
This is a theoretical review proposing a hypothesis, not original research data demonstrating causation. It does not provide experimental evidence that inflammation causes ME/CFS symptoms, nor does it prove that anti-TNF treatments would be effective—it only argues they warrant investigation based on the proposed mechanism. The paper synthesizes existing literature rather than presenting new empirical findings.
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 →
