1 Late posttraumatic epilepsy usually occurs within the first 2 years after the injury. Seizures are believed to originate from a cerebromeningeal scar.26 The 5-year and 30-year cumulative incidence after severe head injury was 10% and 16.7%, respectively.27 The likelihood of late posttraumatic epilepsy is increased by the presence of any of 3 factors: an acute hemorrhage, a depressed skull fracture, and early epilepsy.28–31 Annegers and colleagues found that the presence of early posttraumatic epilepsy did not predict late posttraumatic epilepsy.32 Source: Focal Nonepileptoform Activity, Atlas of Pediatric EEG Citation: Laoprasert P.
