Neuroendocrine Signature of ME/CFS: Meta-Analytic Evidence for Bioactive Cortisol Deficit and Exaggerated Feedback Sensitivity
A new meta‑analysis of neuroendocrine studies in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) reveals a consistent deficit in bioactive cortisol and an exaggerated hypothalamic‑pituitary‑adrenal (HPA) feedback loop. The pooled data indicate roughly a 30% reduction in free cortisol levels compared with healthy controls, while feedback sensitivity is heightened, dampening stress‑induced cortisol release. These hormonal abnormalities correlate with the severity of post‑exertional malaise and other core symptoms. The authors argue that cortisol metrics could serve as objective biomarkers for diagnosis and guide low‑dose glucocorticoid therapies.
BOLD fMRI Reflects Both Vascular and Metabolic Signals
A new quantitative fMRI study by Epp et al. demonstrates that the blood‑oxygenation‑level‑dependent (BOLD) signal reflects both vascular blood‑flow changes and metabolic oxygen‑consumption shifts, and that these two components are not always tightly coupled across the brain. The authors argue that...
