With brainstem infarction, the prognosis is generally poor. Most patients will have more serious sequelae, and some patients recover better if they do not develop complications. Brainstem infarction is mainly caused by bleeding in the brainstem area due to atherosclerosis, embolism, as well as aortic vasculitis and arterial entrapment. Its main symptoms include nausea, vomiting, dizziness, blurred vision, double vision, difficulty in swallowing, unclear speech, limb paralysis, tremor, etc. In severe cases, respiratory difficulties, coma until life-threatening. The prognosis of brainstem embolism is generally poor, and the consequences are more serious than those of other parts of cerebral infarction, with patients suffering from severe disability and a higher mortality rate. The severity of the attack, the amount of bleeding, the age at the time of the attack, and the cause of the brainstem infarction are the main factors affecting the prognosis. In a few cases, the infarct lesion is small, and after standardized treatment and rehabilitation, the recovery is good, without the possibility of sequelae, and the abnormality is basically invisible. Therefore, early detection and early treatment are most important. Once the symptoms related to brainstem infarction are found, it is necessary to consult a doctor immediately, improve the examination and cooperate with the doctor’s treatment.
