The number of years a patient can live with cerebral infarction hemiplegia varies from person to person. Some patients can survive for decades or even for life without affecting life expectancy; some patients can survive for months, weeks or even years, depending mainly on whether the patient has complications and the severity of the condition. If the patient develops hemiplegia alone, without complications, it usually does not affect life expectancy, but mainly affects the patient’s quality of life. When patients have comorbidities, the treatment is less effective and the mortality rate is higher. Cerebral infarction is a common and frequent disease in neurology, mostly occurring in middle-aged and elderly people, and can be clinically divided into infarction of the internal carotid artery system and infarction of the vertebral basilar artery system. Patients with infarction of the internal carotid artery system mainly manifest sensory impairment, motor impairment and hemianopia and hemiparesis, a kind of hemiplegic limb movement disorder, and in severe cases, patients can also develop consciousness impairment. In infarction of the vertebral basilar artery system, patients present with dizziness, nausea, vomiting, and can develop balance disorders and ataxia.
