[Vertebrogenic dizziness, etiology and differential diagnosis].

Cervical-induced vertigo may be caused by degenerative or functional disorders of the cervical spine. Explaining its pathophysiology, disorders of the cervical spine itself, the vertebral artery and the entire cardiovascular system must be taken into account. 66 patients with signs of cervical-induced vertigo were examined neuro-otologically, the function of the cervical spine was judged by X-ray and clinical examination. Moreover, a special provocation of the cervical spine was made--when patients were sitting and in supine position with the head in different directions--including simultaneous ENG recording. With regard to the complaints of the patients and all clinical findings, a selection could be made in 3 groups of signs: A = the degenerative cervical syndrome, B = the irritative cervical syndrome, C = the vertebralis-basilaris syndrome.
