If the patient is of advanced age and has hypertension, diabetes, hyperlipidemia or long-term smoking and alcohol consumption, it means that the patient has a vascular basis and belongs to the high-risk group of cerebrovascular disease. The main function of atorvastatin is to stabilize the atherosclerotic plaque, make it tight and difficult to dislodge, and prevent small cerebral embolism after dislodging. Nimodipine, nicergoline, edebenone or olanzapine capsules can also be used to improve brain metabolism and promote brain nerve cell nutrition to prevent the occurrence of vascular cognitive impairment. As for lacunar cerebral infarcts and ischemic foci that have been seen on imaging, even after the above treatments, the foci are unlikely to be reduced and are classified as fixed damage that has already occurred.
