Dizziness and head buzzing are manifestations of cerebral atherosclerosis, mostly seen in middle-aged and elderly people.1. Cerebral atherosclerosis can cause inadequate blood supply to the brain and inadequate blood supply to the brain in the posterior circulation, which can cause manifestations of cerebellar brainstem ischemia, and patients can experience dizziness, nausea and vomiting, as well as ataxia and dysarthria; at the same time, they can have difficulty swallowing and choking on water, and can also experience diplopia, etc.2. Patients with cerebral atherosclerosis The narrowing of the lumen, stiffness of the wall and poor elasticity of the wall may cause the patient to feel a buzzing in the head as the blood flows against the wall. The main risk factors for cerebral atherosclerosis include hypertension, hyperlipidemia, hyperglycemia and hyperhomocysteinemia, among others. For patients with hypertension, amlodipine or valsartan should be given to actively regulate blood pressure; for patients with hyperglycemia, metformin and regeneronide should be given to lower blood sugar; for patients with hyperlipidemia, oral simvastatin, resulvastatin and atorvastatin should be given to regulate lipids and stabilize plaque to prevent severe atherosclerosis that can cause cerebral infarction.
