Pathogenesis

• The three main theories on the ethiopathogenesis of cervical vertigo are widely believed :

• overexcitation of cervical sympathetic nerves

• abnormally increased neck (cervico-ocular) reflex due to hyperexcitation of neck proprioceptors

• ischemia due to mechanical compression or stenosis of the vertebral artery

• All these theories are well supported clinically and experimentally, so multiple mechanisms in the etiology of cervical vertigo must be considered.
