The symptoms of dizziness in cerebral infarction should be distinguished from those of dizziness in other diseases. When dizziness occurs in cerebral infarction, most of the symptoms of dizziness occur suddenly, accompanied by rotation of vision, along with nausea and vomiting, which lasts for about several minutes or half an hour before it can be relieved. It may also be accompanied by symptoms of posterior circulation ischemia, such as tinnitus, hearing loss, difficulty swallowing, choking and coughing, and some patients may also have 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.
