Posterior cerebral injuries often result in a certain degree of sequelae, the severity of which is highly dependent on the severity of the injury. The more severe the primary injury, the more severe the sequelae, for example, the patient may have obvious cranial nerve dysfunction, manifested by hemiparesis, aphasia, obvious cognitive decline, resulting in low intelligence and obvious reduction in calculation ability, memory ability and orientation judgment of time, space and people. If the primary injury is mild, the sequelae of the injury are often mild, mostly characterized by recurrent headache, dizziness, nausea, vomiting, and obvious memory loss, poor sleep quality at night, insomnia, dreaminess, and easy to wake up.
