Brain attacks tend to recur more often than not and get worse one at a time. Cerebral infarction is a common cerebrovascular disease in the elderly. Because each recurrence of cerebral infarction may cause a new infarction in a different part of the brain, which may cause new neurological deficits or aggravate the original neurological deficits, the recurrence of cerebral infarction will be more serious than before. Therefore, the recurrence of cerebral infarction will be more serious than before. The incidence of cerebral infarction is characterized by high morbidity, high disability, high mortality and high recurrence rate. Especially for people with hypertension, diabetes mellitus and other underlying diseases, once they have had a cerebral infarction, it is more important to apply secondary prevention drugs for cerebrovascular diseases for a long period of time and monitor the blood pressure and blood glucose situation to minimize the recurrence rate of the disease. Patients with cerebral infarction should have regular checkups and actively control the underlying diseases so as to reduce the recurrence rate.
