There is a difference between cerebral infarction and cerebral hernia. Cerebral infarction is caused by necrosis of brain tissue due to various causes of ischemia and hypoxia, causing acute neurological deficits in patients. The symptoms may include hemiparesis, numbness, inflexibility, clumsy speech, slanting of the mouth, visual field loss, difficulty in swallowing, and dizziness. Brain herniation is when the brain tissue exceeds a certain threshold, called brain herniation, and increased intracranial pressure is the determining condition that causes brain herniation. Brain herniation is a very dangerous and critical clinical condition that occurs rapidly within a short period of time and may cause unstable vital signs and lead to the death of the patient. The causes of brain herniation formation are mainly related to increased intracranial pressure. Brain herniation may be commonly caused by cranial injuries, such as acute epidural hematoma, subdural hematoma, cerebral contusion or hypertension, resulting in massive bleeding in the patient’s brain, brain tissue edema caused in the case of massive cerebral infarction, intracranial tumors or tumors in the posterior cranial fossa, all of which may cause brain herniation in patients.
