Risk factors for post-traumatic epilepsy

Traumatic brain injury (TBI) has been identified as a common cause of acquired epilepsy since antiquity. A set of definitions have been adopted by many researchers in defining post-traumatic seizures (PTSs): (1) Immediate PTSs, which occur less than 24 hrs after injury; (2) Early PTSs, that occur less than one week after injury; and (3) Late PTSs, which occur more than a week after head injury and constitute the diagnosis of post-traumatic epilepsy (PTE) [1]. Epidemiological studies have shown a clear relationship between the severity of head injury and the likelihood of developing PTE [1,2].
