It is possible for patients with cerebral infarction in their 80s to recover, although the older the patient is, the worse the immune function of the organism as well as the organ function, and the more difficult it is to recover, but the severity of cerebral infarction is not only related to age, but also depends more on the site and extent of the infarction. If the patient has a brainstem infarction or a large cerebral infarction, even if the patient is young, it can cause severe neurological deficits and make full recovery difficult. If the patient is a lacunar cerebral infarction, even if the patient is over 80 years old, the patient may not have any clinical symptoms at all due to the mild neurological damage and the patient may still recover completely. Moreover, many patients with cerebral infarction over 80 years old can recover well through intravenous thrombolysis and endovascular treatment, together with regular anti-atherosclerosis and rehabilitation, even if they have different degrees of neurological impairment.
