This review examines dysautonomias—conditions where the autonomic nervous system (the part of your body that controls heart rate, blood pressure, and other automatic functions) stops working properly. The authors discuss how these problems can range from occasional fainting spells to serious nerve damage. Importantly, they note that ME/CFS patients often show signs of orthostatic intolerance (difficulty maintaining blood pressure when standing), but a common treatment that works for other autonomic conditions does not appear to help ME/CFS patients.
This paper is significant because it explicitly connects ME/CFS to dysautonomia research and documents the high prevalence of orthostatic intolerance in ME/CFS patients via objective testing (tilt-table). The observation that standard autonomic treatments fail in ME/CFS suggests the condition may involve different underlying autonomic mechanisms than classic dysautonomias, which could guide future therapeutic research.
This review does not establish causation between autonomic dysfunction and ME/CFS symptoms, nor does it prove that orthostatic intolerance is the primary driver of ME/CFS pathology. The paper does not clarify why fludrocortisone fails in ME/CFS or provide a unifying mechanism for autonomic abnormalities in this population. Cross-study comparisons are informal, and treatment efficacy claims rely on existing literature rather than new clinical trial data.
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 →
