1.Vertigo is a symptom that develops when the patient complains of dizziness, seeing things spinning, or a sense of floating by themselves. It is divided into vestibular peripheral vertigo and vestibular central vertigo according to the location of the lesion. Peripheral vertigo refers to lesions of the inner ear and vestibular organs, which are simply related to the ear, such as benign positional vertigo (vertigo attacks related to changes in one’s own position) and Meniere’s disease, which are often mentioned. Central vestibular vertigo refers to lesions of the brainstem, cerebellum, etc., which are simply considered to be related to the brain. Clinically, 70%-80% of vertigo belongs to peripheral vertigo. Although peripheral vertigo has obvious symptoms (severe vertigo, afraid to open eyes, vomiting), it has little effect on a person’s body or life. 2. Peripheral vertigo usually has a relatively short onset and can be accompanied by nausea, vomiting, tinnitus and other symptoms, but not every patient has these symptoms. Central vertigo usually lasts longer, and we encounter vertigo caused by cerebellar infarction in the clinic, which will last from half a month to one month. 3, CT or MRI has a differential value for this and helps to exclude central vertigo.
