Subcortical punctate ischemic foci refer to ischemic foci formed when small capillaries supplying the subcortex, due to arteriosclerosis and occlusion, lead to poor blood flow, resulting in ischemia, hypoxia, and necrosis in the cortex where they supply. All of the above conditions are found during the MRI of the head, which does not bring obvious symptoms to the patient, and there are no positive signs on physical examination. However, the above conditions suggest the presence of multiple sclerosis of capillaries in the brain, and patients should also pay attention to them. Patients are advised to take oral medications to improve cerebral blood circulation, such as ginkgolide drops and blood plugging tablets. If patients have hyperlipidemia they should take oral atorvastatin calcium tablets to lower lipids and stabilize plaque to prevent further aggravation of the degree of atherosclerosis. Oral bai aspirin is taken to antiplatelet aggregation and prevent thrombosis, to prevent the patient’s ischemic foci from increasing and to prevent lacunar cerebral infarction from occurring.
