Cervicogenic headache. The differentiation from common migraine. An overview.
Common migraine and cervicogenic headache have many traits in common, so many that they may be mixed up. Both are unilateral headaches with a female preponderance. However, as for a number of variables, they differ. This first and foremost has to do with factors concerning the neck. In cervicogenic headache, the following symptoms and signs are present: a reduced range of motion in the neck; mechanical precipitation of attack, either by neck movements or by external pressure over the greater occipital nerve of the C2 root; ipsilateral shoulder/arm pain; unilaterality without side-shift. Similar findings are usually not made in common migraine. Typical migraine symptoms, such as nausea, vomiting, photophobia, and phonophobia also occur in cervicogenic headache, but less frequently and to a lesser degree. Operative procedures directed to occipital/nuchal structures may afford decisive differentiation between the two disorders. In our estimation, cervicogenic headache and common migraine are two distinct disorders, with their own clinical patterns, pathogenesis, treatment - and, in all probability, also prognosis.
