The exact prevalence of CH in the United States is unknown; Kudrow estimated it to be 0.4% in men and 0.08% in women. [7] Compared with classic migraine, CH is relatively uncommon, with an incidence equivalent to only 2-9% of that of migraine. Prevalence in males is 0.4-1%. In an extensive study of 100,000 inhabitants of the republic of San Marino, the prevalence was 0.07%. The incidence of CH in the United Kingdom is equivalent to that of multiple sclerosis.
