Cerebral infarction has different clinical manifestations depending on the site of infarction and the size of the infarct area, so the survival period varies, and the less symptomatic cerebral infarction can even survive for a long time. Cerebral infarction is also clinically known as ischemic stroke, which is caused by various causes of regional blood supply disorders in the brain tissue, resulting in ischemic and hypoxic necrosis of brain tissue and corresponding neurological deficit symptoms. According to the pathogenesis of cerebral infarction, it can be divided into types such as cerebral thrombosis, cerebral embolism, and lacunar cerebral infarction. The main risk factors are atherosclerosis, hypertension, diabetes mellitus, hyperlipidemia, etc. The main clinical manifestations include hemiparesis, aphasia, choking on water, vertigo and other symptoms, and its specific survival period does not have an exact value in clinical practice. Patients with mild 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 a poor prognosis, which should attract clinical attention. Patients with cerebral infarction need to pay attention to mood fluctuations in daily life and avoid great joy or grief to avoid aggravating the disease.
