People with cluster headache tend to have higher cortisol and lower melatonin levels compared to individuals without headache disorders.
Notes on verification
Confirmed by multiple independent peer-reviewed studies (Leone et al. 1995, Chazot et al. 1984) and a 2020 meta-analysis (Liampas et al.) showing consistent findings of decreased melatonin and altered/increased cortisol rhythms in cluster headache patients vs controls.
