This is an early case-control study from 1958 examining what was then called benign myalgic encephalomyelitis. The researchers described and compared cases of the condition, though specific details about their findings are not available in the abstract. This represents one of the earliest formal medical investigations into what we now know as ME/CFS.
This study is historically important as one of the earliest formal medical investigations into ME/CFS and demonstrates that the condition was recognized and studied in medical practice over 65 years ago. Early clinical observations like these helped establish ME/CFS as a legitimate medical condition worthy of scientific attention, laying groundwork for modern research.
This study cannot establish the biological mechanisms, causes, or pathophysiology of ME/CFS due to its early date and limited investigative tools. Case-control data from 1958 cannot prove whether findings represent true disease markers or artifacts of clinical observation without modern standardization. The study's age means it cannot provide evidence about modern understanding of ME/CFS genetics, immunology, or neurobiology.
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 →
