The vertigo can be caused by posterior circulation ischemia, especially if the patient has hypertension, diabetes and other risk factors for cerebral atherosclerosis, resulting in poor vascular elasticity, which can manifest as sudden vertigo, accompanied by nausea and vomiting, and in severe cases, visual rotation. For vertigo caused by posterior circulation ischemia, it is recommended to improve the circulation and treat the symptoms. Secondly, vertigo can also be seen as peripheral vertigo, which is commonly seen in Meniere’s syndrome and can be triggered by poor sleep or after exertion. The dizziness of the head can also be seen in some patients who have not slept well. After a bad sleep, due to the chronic lack of oxygen in the brain cells, the patient can have this dizziness, which will be improved soon after a good rest.
