Traumatic epilepsy is a condition in which a patient suffers sudden head trauma that results in intracranial hemorrhage or severe trauma and is treated for residual epilepsy, but such a condition is not defined as traumatic epilepsy. There is no clinical term for traumatic epilepsy; trauma is only a causative factor for epileptic disorders. It can be clinically divided into the following categories: 1. early epilepsy, within 3-4 days after injury, mostly seen in children under 5 years of age, especially under 2 years of age, mostly triggered by cerebral contusion, subarachnoid hemorrhage, intracranial hematoma or acute cerebral edema, prone to persistent epilepsy; 2. delayed epilepsy, within days to 3 months after injury, mostly occurring in children with penetrating injuries and depressed fractures; 3. late epilepsy, more than 3 months after injury, mostly associated with ventricular penetration malformation, cerebral atrophy, hydrocephalus, etc.
