Epidemiology

This is one of the few primary headaches that affect men predominantly (male-to-female ratio varies between 2.5:1 and 3.5:1).[1][6][7] Studies suggest the prevalence of cluster headache is likely to be at least one person per 500, and between 8% and 10% in a headache clinic population.[8][9] The age of onset is usually between 20 and 40 years. Although extremely rare, it has been reported in children as young as 6 years of age. Approximately 90% of affected people have the episodic form; 10% have the chronic form.[10]
