Sometimes there are many clinical reasons for dizziness. First, peripheral vertigo is common. Peripheral vertigo refers to the vertigo caused by changes in vestibular receptors and extracranial segments of vestibular nerves. The vertigo is severe and lasts for a short time. It is commonly seen in Meniere's disease, benign paroxysmal positional vertigo, vestibular neuritis, labyrinthine stroke and other diseases. 2、 It can also be seen in central vertigo. Central vertigo refers to vertigo caused by lesions in the intracranial segment of vestibular nerve, vestibular nerve nucleus, supranuclear fibers, medial longitudinal bundle, cerebellum and cerebral cortex. The vertigo is relatively light, but it lasts for a long time. It is commonly seen in diseases such as vertebrobasilar artery insufficiency, brain stem infarction, cerebellar infarction or hemorrhage. 3、 Repeated dizziness may also occur in hypertension, hypotension, arrhythmia, heart failure, diabetes, hypoglycemia, uremia, poisoning, infection, anemia and other diseases.
