This study looked at whether doctors in ME/CFS clinics were accurately diagnosing psychiatric conditions like depression and anxiety in their ME/CFS patients. Researchers compared diagnoses made by clinic doctors with diagnoses made using a standardized psychiatric interview on 135 patients. They found that doctors missed psychiatric diagnoses in about 22% of patients, but incorrectly diagnosed them in only 10%—meaning missed diagnoses were more than twice as common as false diagnoses.
Many ME/CFS patients experience coexisting psychiatric symptoms, and accurate diagnosis is essential for appropriate treatment planning. This study reveals that standard clinic practices may overlook psychiatric conditions in over one-fifth of patients, potentially leaving treatable mental health issues unaddressed. Understanding diagnostic gaps helps improve clinical training and patient care in specialized ME/CFS centres.
This study does not establish whether psychiatric conditions cause ME/CFS or result from it; it only examines diagnostic accuracy in routine practice. It does not prove that all missed diagnoses represent true psychiatric disorders requiring treatment, nor does it evaluate whether treating identified psychiatric conditions improves ME/CFS outcomes. The findings are from a single UK centre and may not reflect practice worldwide.
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 →
