Subacute subdural hematoma may result in death or in permanent brain damage if untreated or, in some cases, even if treated. This is especially true in the setting of trauma because the mechanism of injury resulting in subdural hematoma is so severe that usually there is other underlying brain injury. Symptoms such as seizures may persist for several months after treatment. Seizures may begin as late as two years after the injury. In adults, most recovery occurs in the first six months, with some improvement over approximately two years.
Children usually recover more quickly and completely than adults.
Incomplete recovery is the result of permanent brain damage. Any person with a serious head injury should have his neck immobilized.
