Patients with cerebral ischemic foci should try to intervene early because the occurrence of cerebral ischemic foci is mainly related to the sclerosis and occlusion of the deep penetrating arteries in the brain, and is associated with long-term hypertension and poor control of hyperglycemia. Therefore, these patients should usually initiate primary prevention medication for cerebrovascular disease, and patients should take oral aspirin or clopidogrel hydrogen sulfate to achieve the effect of antiplatelet aggregation and prevent cerebral thrombosis. In addition, lipid regulation, plaque stabilization and endothelial protection should be given, as well as control of the main causes of cerebral ischemic foci, such as control of hypertension, diabetes and hyperlipidemia. In addition, we should exercise properly, ensure good rest, and pay attention to low-salt, low-fat and light diet.
