How long a person who has had a cerebral infarction will live varies from person to person, depending on the severity of the condition and the patient’s physical condition. In severe cases, cerebral infarction can be life-threatening within a few days, while in milder cases, it usually has no effect on life expectancy. Cerebral infarction is caused by the occlusion of cerebral arteries, which can be caused by atherosclerosis, cardiac embolism and other reasons. If the infarction area is large and the infarction is located in the brainstem and other important brain function areas, it is often life-threatening, and the patient may die within a few days to a few months. If the infarction area is small, the condition is mild, or the patient is in the recovery period of cerebral infarction, if there is no serious complication, it will not affect the natural life of the patient. Cerebral infarction is an acute cerebrovascular disease, symptoms should be diagnosed and treated in time to avoid delayed treatment, resulting in serious consequences.
