A meta-analysis found that symptoms followed a circadian pattern in 71% of cluster headache patients.
Notes on verification
Confirmed by peer-reviewed meta-analysis (Benkli et al., Neurology 2023) reporting 70.5% (~71%) circadian pattern prevalence across 16 studies/4953 patients; corroborated by AAN press release and multiple independent medical news outlets, plus a 2025 follow-up citing the same figure.
