This review looked at the connection between ME/CFS and sleep problems. Many people with ME/CFS experience non-restorative sleep (where sleep doesn't feel refreshing) and fatigue, but these same symptoms can happen with other sleep disorders. The key finding is that doctors need to carefully check whether patients have a separate sleep disorder before or alongside an ME/CFS diagnosis, because treating the sleep problem might help improve overall quality of life.
This study is important because it highlights a critical clinical problem: symptoms that look like ME/CFS might actually be caused by treatable sleep disorders. By helping doctors recognize and properly diagnose underlying sleep problems in ME/CFS patients, better-targeted treatments could improve symptoms and quality of life. Understanding this overlap is essential for developing more effective care strategies.
This review does not establish causal relationships between sleep disorders and ME/CFS, nor does it prove that treating sleep disorders will cure ME/CFS. It also does not present new empirical data—it synthesizes existing literature—so it cannot quantify exactly how many ME/CFS patients have comorbid sleep disorders or define optimal diagnostic criteria for distinguishing between them.
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 →
