ME/CFS is a disorder that causes persistent tiredness, but doctors cannot diagnose it with a simple blood test or scan. Instead, doctors use specific clinical criteria to identify the condition, while carefully ruling out other illnesses like depression or sleep problems that can look similar. Currently, there is no cure for ME/CFS, so treatment focuses on managing individual symptoms like poor sleep, pain, and mood changes with a combination of medical care and psychological support.
This work is significant because it clarifies that ME/CFS is defined by clinical criteria rather than laboratory tests, helping patients understand why diagnosis can be challenging. The emphasis on an integrated medical-psychological approach and prevention of secondary complications has influenced patient care models and highlights the need for both medical validation and mental health support in ME/CFS management.
This editorial does not establish the underlying biological cause of ME/CFS, nor does it provide data proving ME/CFS is distinct from psychiatric conditions—it only frames this as an ongoing clinical question. The review does not evaluate the effectiveness of recommended treatments through controlled trials; it reflects expert consensus on management approaches available at the time.
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 →
