This study looked at whether certain brain chemicals called neuroactive steroids might explain why people with liver disease feel extremely tired. Researchers measured these chemicals in patients with two types of liver disease and compared them to healthy people. They found that patients with liver disease had higher levels of these chemicals, and those with the most fatigue had the highest levels.
This study identifies a potential shared biological mechanism linking liver disease fatigue to ME/CFS, where similar neuroactive steroid elevations have been previously documented. Understanding whether neuroinhibitory steroid accumulation contributes to ME/CFS fatigue could open new diagnostic and therapeutic avenues for a symptom that affects nearly all ME/CFS patients.
This study does not prove that neuroactive steroids cause fatigue in ME/CFS or that the mechanism operates identically across different diseases. It is a small, preliminary cross-sectional correlation study in liver disease patients and does not establish causation or test whether reducing these steroids would improve fatigue. Generalizability to ME/CFS requires direct replication in ME/CFS 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 →
