Causes of cervical vertigo: lesions in the cervical spine, such as cervical arthropathy, vascular lesions, inflammation of the soft tissues of the cervical spine, trauma, etc. Pathogenesis: Mechanical compression and distortion of the vertebral artery caused by the above causes, or spasm of the vertebral artery caused by sympathetic excitation, or disturbance of proprioceptive afferents to the motor receptors in the neck. Clinical manifestations: episodes of vertigo, diplopia, nystagmus with nausea and vomiting, tinnitus, hearing loss (the above symptoms are often associated with changes in neck position), or sudden weakness of the lower limbs with sudden collapse, but consciousness. The symptoms occur mostly when the head and neck are in a certain position. Occasionally, there is numbness of the limbs, abnormal sensation, or transient paralysis, or episodic syncope may occur.
