title: Cervicogenic headache: a review comparison with migraine, tension-type headache, and whiplash.
abstract: Cervicogenic headache (CEH) is a well-recognized syndrome. Proposed diagnostic criteria differentiate CEH from migraine and tension-type headache (TTH) in most of the cases. The best differentiating factors include side-locked unilateral pain irradiating from the back and evidence of neck involvement--attacks may be precipitated by digital pressure over trigger spots in the cervical/nuchal areas or sustained awkward neck positions. Migrainous traits may be present in some cases. Cervical lesions are not necessarily seen, and most common cervical lesions do not produce CEH. Whiplash may occasionally induce headaches. This is suspected when the pain onset and the whiplash trauma are close in time. Whiplash-related headaches tend to be short-lasting, admitting mostly a TTH or a CEH-like phenotype. Neuroimaging abnormalities are not necessarily expected in CEH. Whiplash patients must undergo cervical imaging mostly in connection with the trauma, as no abnormalities are pathognomonic in chronic cases.
