Cerebral infarction recurrence is most dangerous within one year. Cerebral infarction recurs most often within one year, and the recurrence rate is about 20%, especially in the first month after the infarction, the recurrence rate is about 15%, so in one year the patient pays special attention to the danger of recurrence of cerebral infarction. Therefore, patients need to take medication for a long time to prevent the recurrence of cerebral infarction. And patients should not relax their vigilance just because there is no recurrence for a long time. Patients must quit smoking and drinking, eat a low-salt and low-fat diet, and control their weight appropriately. It is suggested that patients should control blood pressure and blood sugar, avoid too much emotional excitement, do not stay up too late, control the dietary pattern, develop a good sleeping habit, and can enhance their resistance through appropriate exercise.
