This study found that people with ME/CFS who experienced childhood trauma (such as abuse or neglect) have significantly different stress hormone levels compared to healthy people. Specifically, those with ME/CFS and childhood trauma history showed lower cortisol (a stress hormone) levels after waking up. The research suggests that early difficult experiences may damage the body's stress-response system in ways that increase vulnerability to developing ME/CFS later in life.
This study provides evidence that childhood trauma may be a causal or co-causal factor in ME/CFS development by programming dysfunction in the HPA axis—a key system implicated in the disease pathophysiology. Understanding this link helps explain why some patients develop ME/CFS and identifies potential prevention and treatment targets, including trauma-informed care approaches for at-risk populations.
This study does not prove that childhood trauma causes ME/CFS—it demonstrates association in a cross-sectional design where trauma exposure was self-reported retrospectively, introducing recall bias. The study cannot rule out reverse causation or establish whether blunted cortisol is a cause or consequence of ME/CFS. Additionally, findings apply to the study population and may not generalize to all ME/CFS patients or non-Western populations.
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 →
