This paper brings together expert opinions about how the autonomic nervous system (the part of your nervous system that controls automatic functions like heart rate and breathing) may be involved in ME/CFS. The authors reviewed what was known in 2000 about connections between autonomic nervous system problems and other system dysfunctions seen in ME/CFS, including immune and hormone abnormalities.
This consensus statement helped legitimize investigation of autonomic dysfunction as a core feature of ME/CFS, moving beyond single-system explanations. By highlighting connections between the nervous system, immune system, and endocrine system, it encouraged researchers to study ME/CFS as a multisystem disorder, which has guided research direction for decades.
This consensus paper does not provide new experimental evidence proving that ANS dysfunction causes ME/CFS symptoms. It does not establish causation, only summarizes existing knowledge and expert opinion about potential associations. It also cannot definitively explain the mechanisms by which ANS dysfunction contributes to disease pathophysiology.
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 →
