In clinical work, we often encounter patients with vertigo, “What exactly is cervical vertigo?” It is a question that plagues many patients! The following is a brief description of my understanding: “cervical vertigo” is not a specific disease name, but refers to a type of central vertigo caused by insufficient blood supply to the vertebral artery due to certain causes such as cervical spondylosis, so in general, “cervical vertigo” is basically referred to as a result of cervical spondylosis. So, is there any characteristic of vertigo caused by cervical spondylosis that can distinguish it from other vertigo? One is that the pushing vein is mechanically compressed by bone spurs and becomes narrowed or occluded, which is easier to happen when the pushing vein itself is diseased; the other is that the cervical sympathetic nerve is stimulated and causes spasm of the pushing vein. In both cases, there is a prerequisite that the head and neck must be turned to a certain position to allow the pushing vein to be compressed or the sympathetic nerve to be stimulated. In short, the vertigo attack is clearly related to the position of the head and is called positional vertigo. Some patients may have a history of sudden collapse, mostly when they hear shouting behind them while walking, and when they look back, they suddenly fall to the ground with weakness in their lower limbs, and after they fall to the ground, their head position returns and the symptoms disappear, and they can get up immediately. Cervical vertigo is characterized by positional vertigo of the head and neck, which occurs when the head and neck are turned or laterally flexed to a specific position, and the symptoms disappear after the position is returned. After 2-3 episodes, the patient is conscious of this and is very alert to avoid this specific position. However, when the pushing pulse type cervical spondylosis has the role of pushing pulse sympathetic plexus involved in it, or when it occurs mixed with sympathetic type cervical spondylosis, the vertigo symptoms can become atypical and unusually complicated to distinguish.
