In mild cases of subdural hemorrhage, there are no obvious sequelae, while in severe cases, there are sequelae of neurological function. Sequelae of neurological function left behind by acute subdural hemorrhage include limb motor dysfunction such as balance function, walking function, decreased ability of daily life, limb sensory dysfunction such as decreased sense of touch, speech dysfunction such as unclear expression, autonomic dysfunction such as urinary and fecal incontinence, sweating abnormality, epilepsy, and so on. Subdural hemorrhage is divided into acute subdural hemorrhage and chronic subdural hemorrhage. Chronic subdural hemorrhage is treated with timely drilling and drainage surgery, and patients basically have no sequelae. On the other hand, acute subdural hemorrhage is usually caused by intracranial hemorrhage due to trauma, especially bleeding from small arteries in the cerebral cortex and cerebral contusion, which will lead to cerebral nerve damage, and therefore serious neurological sequelae will occur. The sequelae left behind by subdural hemorrhage are recommended to seek timely medical treatment under the guidance of doctors to promote their recovery.
