Cerebral infarction is associated with dizziness, which is mostly suggestive of posterior circulation ischemia, such as brainstem infarction and cerebellar infarction. The vestibulocochlear nerve nucleus is located in the bridge of the brain, which is mainly responsible for the balance of the organism and conduction of hearing, etc. When the brainstem infarction, the vestibulocochlear nerve nucleus is damaged, and symptoms such as vertigo, nausea, vomiting, or balance disorders will occur. Since the respiratory and heartbeat centers, which control the body, are also located in the brainstem, life-threatening respiratory and cardiac arrests can easily occur if treatment is not timely. The cerebellum is mainly responsible for body balance and coordinating movement, etc. When cerebellar infarction occurs, the body will experience ataxia, dizziness, unsteady walking, etc., which is prone to accidents. Cerebral infarction patients with dizziness are recommended to be hospitalized in time for diagnosis and treatment.
