It is well known that migraine with aura may coexist with various unilateral headaches, like cluster headache and chronic paroxysmal hemicrania. It may also coexist with cervicogenic headache. The diagnosis of migraine without aura ("common migraine") poses greater problems than the diagnosis of migraine with aura. ⋯ The mean number of cervicogenic headache criteria was 4.3 (out of a total of 5) in the "cervicogenic part of the picture", as opposed to 1.5 (1.8 if laterality is considered, see text) in the "migraine part of the picture". Drug regimens and anaesthetic blocks also showed different results in the two different headaches in the same patient. All in all, this study seems to support a coexistence of the two headache types.
