The survival rate of cerebral infarction is about 85% or more, and the disability rate of surviving patients is about 50%. There are many factors affecting the prognosis of patients with cerebral infarction, the most important of which is the severity of neurological deficits, while other factors include the age of the patient and the etiology of stroke, etc. Cerebral infarction is an acute ischemic cerebrovascular disease. Cerebral infarction is an acute ischemic cerebrovascular disease, a common and frequent disease in neurology, mostly occurring in middle-aged and old people, and patients can have different clinical symptoms and signs, mainly depending on the size of infarct foci and infarction sites. If the patient has large hemispheric infarction and brainstem infarction, the clinical symptoms and signs are generally more serious, and the patient may have consciousness disorder, cerebral edema and increased intracranial pressure, which may cause the patient’s death in serious cases. Patients with brain stem infarction can usually present with bulbar palsy and quadriplegia. Patients with mild cerebral infarction and small-sized infarction have milder clinical symptoms and signs, most of which are signs and symptoms of focal neurological deficit. Generally there is no consciousness disorder and cerebral edema, the treatment effect of patients is better, most patients can be clinically cured, and generally will not leave sequelae.
