The symptoms of dizziness in cerebral infarction should be distinguished from the symptoms of dizziness in other diseases. In most cases of cerebral infarction, dizziness occurs suddenly, accompanied by visual rotation, nausea and vomiting, and lasts for several minutes or half an hour before it can be relieved. There may also be symptoms of posterior circulation ischemia, such as tinnitus, hearing loss, difficulty swallowing, choking and coughing, and in some cases, blurred vision. It also manifests as weakness of both lower limbs and a cotton-like sensation when walking on both lower limbs, and patients need to be hospitalized.
