Patients with old cerebral infarction should exercise moderately, lose weight, quit smoking and drinking, eat reasonably, and have a balanced mentality while controlling related diseases, such as hypertension and diabetes mellitus, in their daily life. Comprehensive interventions such as lifestyle changes and medication are effective in preventing the recurrence of cerebral infarction, and the main drugs for preventing the recurrence of cerebral infarction are anti-platelet aggregation drugs such as aspirin and plaque stabilizing drugs such as atorvastatin, so discontinuing the use of statin for one month may have the risk of recurrence of cerebral infarction.
