Patients with cerebral infarction need to prevent recurrence through lifestyle improvement, medication and regular review. 1. Lifestyle improvement: Daily diet should be light and highly nutritious, with less exposure to foods that are too oily or contain more sugar, and more vegetables and fruits can be consumed to supplement vitamins and fiber. It is also necessary to quit smoking and drinking, appropriate exercise, conservative and stable emotions, and ensure sufficient sleep. 2. Medication: Control hypertension, hyperlipidemia, diabetes mellitus and other related diseases, and take long-term oral antiplatelet aggregation or anticoagulation, plaque stabilization medication after cerebral infarction to prevent recurrence. 3. Regular checkups: regular outpatient follow-up, early detection of vascular problems, such as vascular stenosis, etc., and early treatment to prevent cerebral infarction. Prevention of cerebral infarction requires a combination of clinical and lifestyle measures. Even if all the above measures are taken, there is still a possibility of recurrence of cerebral infarction because age is an uncontrollable risk factor for cerebral infarction and the risk of cerebral infarction increases with age. Patients with cerebral infarction are advised to seek timely medical consultation and standardized treatment under the guidance of a physician to prevent recurrence.
