”Cervical vertigo” is not a specific disease, but refers to a type of central vertigo caused by insufficient blood supply to the vertebral artery due to certain diseases, and vertigo is most common in cervical spondylosis, so cervical vertigo is used to refer to vertigo caused by cervical spondylosis. Patients generally experience that whenever the head is turned or bent sideways to a certain degree, it will trigger or aggravate the symptoms of insufficient blood supply to the vertebral artery, such as vertigo, sudden collapse, nausea, vomiting, diplopia, nystagmus, etc. When the head is turned back to the original position, the symptoms can be reduced or disappear, so that some patients are afraid to turn their heads or bend sideways. This is mainly related to the pathological changes of cervical spondylosis. Under normal circumstances, the vertebral artery that travels in the transverse foramen of the cervical spine can affect the blood supply of one side of the vertebral artery because of head turning. However, the other side can compensate for it, and there is usually no discomfort. When the cervical vertebrae above 6 have hook vertebral joint hyperplasia, the vertebral artery can be directly squeezed, making the vascular cavity smaller and affecting the blood flow of the vertebral artery, especially in the 5th cervical vertebrae, the vertebral artery is closer to the vertebral body, which is more likely to cause compression, and can also stimulate the sympathetic nerve there and cause reflex vasospasm, affecting the blood supply of the vertebral artery even more. In addition, the age of prevalence of cervical spondylosis is also the age of prevalence of atherosclerosis. Arteriosclerosis itself has reduced the compensatory nature of the vertebral artery, and together with cervical spondylosis, vertigo occurs whenever the head is rotated or laterally flexed. Therefore, some patients have a history of sudden collapse, mostly when they hear shouting behind them while walking, and when they turn around, they fall to the ground with weakness of lower limbs, and when they turn around, the symptoms disappear and they can get up immediately. By the same token, we do not advocate traction or heavy manipulation for vertigo patients, and never violence or excessive rotation to avoid the risk of stroke paralysis.
