Cervicogenic Headache: A Personal View

Abstract

Cervicogenic headache describes pain referred along the upper three cervical roots and is a common source of headache in the over tittles. A review of clinical features, anatomy, and investigations using neural blockade shows several clinical pictures. Diseases of the cranio-vertebral junction, e.g. syringomyelia, and tonsilar descent, can produce mechanical or hydrodynamic head and neck pain. Pre-existent migraine and tension headache may be precipitated or aggravated by cervical spondylosis, but the anatomical mechanism is unclear. Headaches which arise from and are primarily caused by disorders in the cervical spine are exemplified by spondylosis and acute whiplash injury, but are usually transient. Evidence for a cervicogenic mechanism of chronic whiplash headache is, however, lacking.
