There is no clear statement on which is more serious, brain hemorrhage or cerebral infarction, but it is mainly determined by the severity of the damage caused to the nervous system by the disease, as follows: 1. Both are very serious: If both brain hemorrhage and cerebral infarction cause serious damage to the nervous system, resulting in obvious symptoms of neurological deficits such as impaired consciousness, hemiparesis and aphasia, then both diseases are very serious. 2. The prognosis of both small lesions is relatively The prognosis of patients with both diseases is relatively good if the scope of both cerebral hemorrhage and cerebral infarction is small and the damage to the nervous system is not serious. Therefore, which is more serious in patients with cerebral hemorrhage or cerebral infarction is judged mainly by the severity of the symptoms and the prognosis of the patient. But in any case, both diseases need to be actively treated after the onset, otherwise they can cause significant neurological damage, which can leave patients with sequelae and even threaten their lives.
