This article reviews the history of ME/CFS, showing that conditions with similar symptoms have existed for hundreds of years under different names like neurasthenia and myalgic encephalomyelitis. A major outbreak at Lake Tahoe in the 1980s brought modern attention to the disease, but doctors realized that not all patients with CFS symptoms actually had evidence of EBV infection, suggesting the disease is more complex than a simple viral cause. The authors explain how understanding this history can help develop better diagnostic guidelines for the condition.
Understanding the long history of ME/CFS—and recognizing it by multiple names—validates patient experiences and helps prevent the disease from being dismissed as new or psychological. The observation that EBV infection doesn't explain all cases was crucial in shifting scientific thinking toward ME/CFS as a distinct biological condition worthy of serious research.
This historical review does not establish causation for any particular ME/CFS trigger or mechanism—it only documents that similar illnesses have been observed across centuries. It does not provide new experimental data, patient cohort analysis, or novel diagnostic tests. The poor correlation between EBV and CFS symptoms suggests EBV alone doesn't cause the disease, but this does not prove what the actual cause is.
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 →
