Patients with cerebral insufficiency can develop tinnitus, mainly in middle-aged and elderly patients. The main cause of cerebral insufficiency in middle-aged and elderly patients is atherosclerosis, and patients often have hypertension, hyperlipidemia, hyperglycemia and hyperhomocysteinemia. Patients with these risk factors should be actively given clinical control, such as oral amlodipine to lower blood pressure and oral statins, such as simvastatin and resevastatin, atorvastatin to regulate lipids and stabilize plaque. Oral hypoglycemic agents, commonly used are metformin to regulate blood glucose, and subcutaneous insulin injection therapy if necessary. For patients with inadequate cerebral blood supply, it can cause multiple vascular sclerosis, and sclerosis of small blood vessels in the ear can lead to inadequate blood supply to the ear, which can cause tinnitus and other discomfort to the patient. For middle-aged and elderly patients with insufficient cerebral blood supply, examination of cranial CT is usually normal, and cranial MRI can show ischemic foci. For younger patients with insufficient blood supply to the brain, most of them are caused by anxiety and tension and usually do not have symptoms such as tinnitus.
