Dizziness, nausea, dryness and vomiting may be caused by hypertension, and blood pressure should be monitored. If blood pressure is elevated, middle-aged and elderly people take oral calcium antagonists, and amlodipine is commonly used in clinical practice. In case of young people, oral candesartan, irbesartan, valsartan, and also oral enalapril can be taken. It may also be caused by posterior circulation transient ischemic attack. The patient’s symptoms are episodic, and the duration of symptoms mostly varies from 10-15 minutes and does not exceed one hour, and is normal at the time of cranial CT examination, occurring mostly in middle-aged and elderly people with acute onset. Cerebral infarction may occur when it occurs frequently. Oral aspirin antiplatelet aggregation therapy can be given, along with the application of statins, such as simvastatin and atorvastatin to regulate lipids and stabilize plaque. If patients have severe dizziness, they can also be treated with oral Cipro, or vertigo stop. If the patient has cerebellar hemorrhage or cerebellar infarction, the above symptoms may also occur.
