This article reviews what scientists know about fibromyalgia as of 2020, including how it's diagnosed and why it happens. The authors explain that fibromyalgia involves the brain processing pain signals too intensely, and that people with fibromyalgia often experience many other symptoms like fatigue, sleep problems, and sensitivity to sounds, lights, and touch. They also discuss how fibromyalgia shares common features with other conditions like ME/CFS, all involving a heightened sensitivity to stimuli controlled by the central nervous system.
This review is important because it positions ME/CFS as part of a recognized family of central hypersensitivity syndromes, validating the legitimacy of neurobiological mechanisms underlying these conditions. For ME/CFS patients, the framework helps explain why they experience multi-system sensory and autonomic symptoms, and suggests that research into fibromyalgia mechanisms may yield insights applicable to ME/CFS pathophysiology.
This editorial does not present new experimental data or prove causality—it synthesizes existing knowledge. It does not establish the precise neurobiological mechanisms driving hypersensitivity, nor does it demonstrate that all patients with ME/CFS and fibromyalgia share identical pathways. The review cannot determine whether these are truly separate conditions or manifestations of a single underlying disorder.
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 →
