Cerebral infarction has different clinical manifestations due to different parts of infarction and different sizes of infarction area, so the survival period is different, and cerebral infarction with milder symptoms can even survive for a long time. Cerebral infarction, also known as ischemic stroke, is caused by a variety of reasons to the local blood supply of brain tissue, and then ischemic and hypoxic necrosis of brain tissue, resulting in corresponding neurological deficiency symptoms. According to the pathogenesis of cerebral infarction, it can be categorized into cerebral thrombosis, cerebral embolism, lacunar cerebral infarction and other types. Its main risk factors include atherosclerosis, hypertension, diabetes mellitus, hyperlipidemia and so on. The main clinical manifestations include hemiparesis, aphasia, choking on drinking water, vertigo and other symptoms, and there is no exact clinical value for its specific survival period. Patients with minor lacunar cerebral infarction can survive for a long time, while patients with large cerebral infarction and brainstem infarction are in critical condition and often have poor prognosis, which should be emphasized clinically. Patients with cerebral infarction need to pay attention to emotional fluctuations in daily life and avoid great joy or great sorrow, so as not to aggravate the condition.
