How long can an 80-year-old brain infarction live?

How long an 80-year-old person can live after a cerebral infarction depends on a variety of reasons, and the size and location of the infarction. If the patient has a large cerebral infarction, the patient's symptoms and signs are severe, and the patient may show high intracranial pressure and consciousness disorders. The patient may die within a week after the onset of the disease due to severe intracranial hernia, or may die of complications. The patient may show complications one week after the onset of the disease, but it may also be one month or longer after the onset of the disease. Common complications include deep vein thrombosis of the lower extremities, which can easily lead to pulmonary embolism and death. Patients can also present with bedsore infections, urinary tract infections, and lung infections. Repeated infections may also lead to death. Patients with small cerebral infarction may not affect their life expectancy.
