The rotation of the sky, dizziness and nausea are vertigo, which is a broad concept including central and peripheral vertigo: 1. Central vertigo is a lesion of the cerebellum and brainstem, including various types of ischemic and hemorrhagic diseases, as well as occupational and inflammatory disorders. Among them, ischemic ones are most common in the elderly, such as posterior circulation ischemia, vertebrobasilar artery blood supply insufficiency, infarction of the brainstem and cerebellum, and then cerebral hemorrhage and intracerebral tumors; 2. Peripheral vertigo is the result of vestibular organ lesions, such as the most common benign paroxysmal positional vertigo, which is caused by cochlear balance dysfunction. Identification of central and peripheral vertigo is mainly based on the patient’s history and physical examination as well as the combination of cranial magnetic resonance and cranial magnetic resonance angiography.
