Cluster headache is considered a male-dominated disorder, but we have previously suggested that females may display a more severe phenotype. Studies on sex differences in cluster headache have been conflicting, therefore this study, with the largest validated cluster headache material at present, gives more insights into sex-specific characteristics of the disease. The objective with this study was to describe sex differences in patient demographics, clinical phenotype, chronobiology, triggers, treatment, and lifestyle in a Swedish cluster headache population.
