Cervicogenic headache is a chronic, hemicranial pain syndrome in which the sensation of pain originates in the cervical spine or soft tissues of the neck and is referred to the head. The trigeminocervical nucleus is a region of the upper cervical spinal cord where sensory nerve fibers in the descending tract of the trigeminal nerve converge with sensory fibers from the upper cervical roots. This convergence of nociceptive pathways allows for the referral of pain signals from the neck to the trigeminal sensory receptive fields of the face and head as well as activation of the trigeminovascular neuroinflammatory cascade, which is generally believed to be one of the important pathophysiologic mechanisms of migraine. Also relevant to this condition is the convergence of sensorimotor fibers of the spinal accessory nerve (CN XI) and upper cervical nerve roots, which ultimately converge with the descending tract of the trigeminal nerve. These connections may be the basis for the well-recognized patterns of referred pain from the trapezius and sternocleidomastoid muscles to the face and head. Diagnostic criteria have been established for cervicogenic headache, but presenting characteristics of this headache type may be difficult to distinguish from migraine, tension-type headache, or paroxysmal hemicrania. This article reviews the clinical presentation of cervicogenic headache, its proposed diagnostic criteria, pathophysiologic mechanisms, and methods of diagnostic evaluation. Guidelines for developing a successful multidisciplinary pain management program using medication, osteopathic manipulative treatment, other nonpharmacologic modes of treatment, and anesthetic interventions are presented.

Cervicogenic headache is a chronic, hemicranial pain syndrome in which the source of pain is located in the cervical spine or soft tissues of the neck but the sensation of pain is referred to the head. The trigeminocervical nucleus is a region of the upper cervical spinal cord where sensory nerve fibers in the descending tract of the trigeminal nerve converge with sensory fibers from the upper cervical roots. This convergence of upper cervical and trigeminal nociceptive pathways allows the referral of pain signals from the neck to the trigeminal sensory receptive fields of the face and head. The clinical presentation of cervicogenic headache suggests that there is an activation of the trigeminovascular neuroinflammatory cascade, which is thought to be one of the important pathophysiologic mechanisms of migraine. Another convergence of sensorimotor fibers has been described involving intercommunication between the spinal accessory nerve (CN XI), the upper cervical nerve roots, and ultimately the descending tract of the trigeminal nerve. This neural network may be the basis for the well- recognized patterns of referred pain from the trapezius and sternocleidomastoid muscles to the face and head. Diagnostic criteria have been established for cervicogenic headache but its presenting characteristics may be difficult to distinguish from migraine, tension-type headache, or hemicrania continua. A multidisciplinary treatment program integrating pharmacologic, nonpharmacologic, anesthetic, and rehabilitative interventions is recommended. This article reviews the clinical presentation of cervicogenic headache, its diagnostic evaluation, and treatment strategies.

Cervicogenic headache is pain perceived in the head but referred from a primary source in the cervical spine. The physiologic basis for this pain is convergence between trigeminal afferents and afferents from the upper three cervical spinal nerves. The possible sources of cervicogenic headache lie in the structures innervated by the C1 to C3 spinal nerves, and include the upper cervical synovial joints, the upper cervical muscles, the C2-3 disc, the vertebral and internal carotid arteries, and the dura mater of the upper spinal cord and posterior cranial fossa. Experiments in normal volunteers have established that the cervical muscles and joints can be sources of headache.

Cervicogenic headache (CEH) is a headache, but its origin is in the neck. Recently, two cases of intracranial tumour, which unfortunately were originally diagnosed as CEH, were published. The authors felt that this sequence of events demonstrates the insufficiency of the current CEH criteria. We--on the other hand--feel strongly that, on the contrary, this small challenge may have demonstrated the robustness of the CEH criteria. The criteria of CEH were actually not fulfilled at any time. We marshal our arguments in support of this view and concentrate on one of their cases (no. 1).

Cervicogenic headache is becoming an accepted clinical syndrome in which headache pain is thought to originate from the cervical spine. Unfortunately, there are no diagnostic imaging techniques of the cervical spine and associated structures that can determine the exact source of pain. Therefore, diagnosis and treatment are based on the major accepted criteria of clinical presentation and the use of diagnostic nerve blocks to identify the source of the pain generator before considering further interventional or neuroablative treatment. This suggests that consistent reproducible anatomic and neurophysiologic pathways exist for the reproduction of typical clinical pain patterns and the ability of neuroblockade to consistently interrupt these pain pathways. This article describes the essential anatomy required to understand the use of diagnostic nerve blocks, and their predictive value in anticipating response to neuroablative and interventional therapy with a review of the major interventional, anesthetic, and ablative techniques for cervicogenic headache.

Cervicogenic headache is a relatively common and still controversial form of headache that originates from the neck structures. The pathophysiology probably results from various local pain-producing factors, such as intervertebral dysfunction, but the frequent coexistence of a history of head traumas still plays an important role. This report represents a series of pathophysiologic studies performed for patients with cervicogenic headache and the results achieved by a new pharmacologic treatment for the disease.

The influence of pregnancy upon the head pain of cervicogenic headache (CEH) has been studied in 14 patients (number of pregnancies 25). Migraine was used as control group (n = 49; number of pregnancies 116). CEH was diagnosed according to The Cervicogenic Headache International Study Group guidelines. Migraine was diagnosed according to International Headache Society (IHS) guidelines; a further requirement was that at least eight of nine solitary IHS diagnostic requirements of migraine were present. In 79%-or more-of CEH patients, attacks seemed to appear just as usual during pregnancy; in one patient, attacks stopped completely, and in two there may have been a minor reduction of attacks. A significantly lower number of migraine patients (up to 18%) were more or less uninfluenced by pregnancy (CEH vs. migraine P < 0.0001, chi2 test). The lack of response to pregnancy may be a sort of biological marker in CEH. It may also help in clinically distinguishing CEH from migraine when CEH starts early in life, i.e. prior to pregnancies.

Cervicogenic headache (CH) originates from disorders of the neck but is recognized as a referred pain in the head. Primary sensory afferents from the cervical roots C1-C3 converge with afferents from the occiput and trigeminal afferents on the same second-order neuron in the upper cervical spine. Consequently, the anatomical structures innervated by the cervical roots C1-C3 are potential sources of CH. In normal volunteers, the painful stimulation of different anatomical structures of the neck produced headache. In CH, particular structures have been selectively anesthetized in order to identify possible sources of pain. In summary, CH can origin from different muscles and ligaments of the neck, from intervertebral discs,and, particularly, from the atlantooccipital, atlantoaxial, and C2/C3 zygapophyseal joints. Diagnosis of CH should adhere strictly to the published diagnostic criteria to avoid misdiagnosis and confusion with primary headache disorders such as migraine and tension type headache.

In a retrospective analysis of 299 consecutive patients with degenerative cervical spine disease the incidence of cervicogenic headache and the results of conservative and operative therapy have been investigated. Cervicogenic headache was noted in 117 of 299 patients (40%). 73 of those patients were treated conservatively. The cervicogenic headache resolved in 10% or improved in 27% and remained unchanged in 63% of the patients. 44 of these patients were operated by ventral discectomy, which was indicated in case of neurological deficit and painful shoulder-arm syndrome refractory to conservative treatment. In none of these patients the operation was indicated by the cervicogenic headache. In the postoperative follow-up with a mean of 6 months the headache resolved in 20%, improved in 60% and remained unchanged in 20% of the patients. These results suggest the existence of a cervicogenic headache, i.e. a headache due to disorders of the cervical spine, and the chance of successful operative treatment.

Cervicogenic headache (CEH) with pain radiating from the neck to the forehead is a common finding after whiplash injury. In most whiplash studies, the whiplash headaches are not defined. Post-whiplash CEH typically is a moderate headache with a benign, but often prolonged course. It probably is unilateral and bilateral. Reduced neck mobility does not seem to be as common after whiplash as in chronic CEH in general. Post-whiplash CEH is accompanied by great disability and high use of medication. Although the natural course seems favorable for unilateral CEH during the first postinjury years, some patients will need specific treatment for their headaches. There is a lack of controlled studies to guide practitioners to choose investigations and treatment for chronic CEH.
