Although the symptoms of mild cerebral infarction are mild, it is easy to have recurrent attacks if the risk factors are not controlled, and the main treatment for mild cerebral infarction is medication. The most important therapeutic drugs are anti-platelet aggregation drugs, mainly including aspirin, clopidogrel, cilostazol and tigretol, etc. These drugs are the basic drugs for the treatment of cerebral infarction by inhibiting platelet aggregation and release, so that the local thrombus no longer progresses and expands, and they should pay attention to the risk of bleeding when taking such drugs, and timely consultation should be made to adjust the medication if gum bleeding or black stool occurs. For patients with atrial fibrillation who consider cerebral infarction caused by small artery embolism, anticoagulant drugs should be used to prevent re-embolism. The commonly used oral anticoagulant drug is warfarin, which requires INR monitoring (control at 2.0~3.0), but there are also some new oral anticoagulants such as dabigatran, which do not require INR monitoring. Since patients with cerebral infarction are often accompanied by high-risk factors such as hypertension, diabetes mellitus, hyperlipidemia, hyperhomocysteinemia, etc., these risk factors should be controlled at the same time, and appropriate antihypertensive drugs, hypoglycemic drugs, and lipid-lowering drugs should be applied under the guidance of doctors. The corresponding antihypertensive drugs, hypoglycemic drugs and lipid-lowering drugs should be applied under the guidance of doctors, among which lipid-lowering drugs usually apply statins, and homocysteine-lowering drugs choose the combination of folic acid and vitamin B12. In addition, some traditional Chinese medicine, such as circulation improvement and nerve nutrition drugs, can also play a supplementary therapeutic role. In conclusion, although mild cerebral infarction has mild symptoms, it is prone to recurrence if risk factors are not controlled, so standardized treatment should be provided for the etiology and the risk factors of cerebrovascular disease present in patients.
