Cerebral infarction is a major disease, which is a common and frequent disease in neurology, mostly occurring in middle-aged and elderly people. Patients have a high rate of disability and death, which seriously affects the quality of life of patients. Patients can present with a variety of clinical symptoms and signs, depending on the location of the lesion and the size of the infarct, including hemiparesis, hemianopia, hemianesthesia, and speech dysfunction. Some patients may experience dizziness, nausea, vomiting, balance disorders, ataxia, dysphagia and choking cough, and in severe cases, bulbar palsy and tetraplegia, as well as impaired consciousness, cerebral edema and increased intracranial pressure. In severe cases of increased intracranial pressure, brain herniation can be caused, leading to direct death of the patient. A proportion of patients may be clinically cured with aggressive and correct treatment. Cured patients also require long-term secondary prophylaxis to prevent reinfarction. A subset of patients may have some sequelae, which may cause lifelong disability to the patient if the patient remains in general.
