Elderly people with dizziness and vomiting should be registered with neurology. Dizziness and vomiting are a group of symptoms, mostly caused by neurological diseases, which are clinically common in cerebrovascular diseases, including cerebellar brainstem hemorrhage and cerebellar brainstem infarction. Patients with cerebral stem hemorrhage usually start during activity, while patients with cerebral stem infarction mostly start in a quiet state or during sleep. Patients may have a history of hypertension, diabetes mellitus, and hyperlipidemia, and may present with both of these symptoms, as well as balance disorders and ataxia, difficulty swallowing and choking on water, and in some cases, nystagmus and diplopia. It may also be caused by cerebellar brainstem tumor or cerebellar brainstem inflammation. Patients with tumor usually have a chronic onset, while patients with inflammation usually have a subacute onset. In addition, it may also be caused by posterior circulation transient ischemic attack. The patient’s symptoms are usually episodic in nature, with a duration ranging from 10-15 minutes in most cases, usually not more than 1 hour, with normal cranial CT examination. The main focus is to improve blood circulation, while controlling the cause of the disease, and if necessary, oral aspirin anti-platelet aggregation therapy can be administered.
