This review article examines what happens in the brain and nervous system of people with ME/CFS. Researchers found that ME/CFS involves real biological changes in the brain—not just fatigue—including problems with mood, thinking, and hormone regulation. The study suggests that ME/CFS is a neurological condition with measurable differences in brain function, rather than purely psychological.
This work is important because it consolidates evidence that ME/CFS involves measurable brain and nervous system dysfunction, validating patient experiences of cognitive and neurological symptoms. By positioning ME/CFS within a neurobiological framework, the study helps shift clinical understanding away from purely psychiatric or deconditioning explanations toward recognition of organic pathology.
This review does not establish causation or identify the specific mechanisms causing neurobiological abnormalities in ME/CFS. It does not provide diagnostic criteria or determine whether neurobiological changes are primary causes or secondary consequences of prolonged illness. The article also does not establish uniform neurobiological signatures across all ME/CFS patients.
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 →
