This editorial argues that three related conditions—POTS, ME/CFS, and Long COVID—should be understood and studied together as disorders affecting both the nervous system and immune system. The authors identify several common problems in these conditions, including heart rate abnormalities when standing, immune system dysfunction, and reduced blood flow to the brain. They believe treating these as a single category of disease could improve how doctors train, research, and care for patients with these serious illnesses.
This perspective is important because it validates the interconnected nature of conditions that often co-occur or overlap in patients, potentially leading to more integrated research and clinical approaches. If adopted, this framework could improve physician understanding and training, leading to better recognition and management of these disabling conditions that currently lack disease-modifying treatments.
This editorial does not provide original experimental data, mechanistic proof, or clinical trials establishing causation for any proposed pathways. It does not demonstrate the prevalence of individual mechanisms across patient populations or prove that reclassification will improve patient outcomes. The piece represents expert opinion rather than empirical evidence of 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 →
