This review examines several long-term illnesses—including ME/CFS—where patients experience real symptoms but standard medical tests don't show an obvious cause. The authors found that some patients do have measurable thinking and memory problems, but these may result from a combination of stress, past trauma, and how the body responds to illness rather than from traditional brain disease alone.
This work is important because it validates that ME/CFS patients' cognitive complaints may reflect real, measurable impairments while also acknowledging the complex biological-psychological interactions underlying the condition. It challenges the false dichotomy between 'organic' and 'psychological' illness, supporting a more nuanced understanding of ME/CFS pathophysiology.
This review does not identify specific biomarkers or primary causes of ME/CFS cognitive dysfunction, nor does it establish causality between any single factor and disease. It cannot determine whether stress causes the cognitive abnormalities or whether the underlying illness causes both cognitive problems and stress responses. The study's reliance on existing literature means findings are limited by the quality and design of reviewed studies.
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 →
