The incidence of posttraumatic epilepsy (PTE) is estimated at 10–20% [1,2], and various risk factors have been noted [2–9]. Approximately 90% of the patients develop PTE within two years during the chronic phase [10,11], but prevalence has been shown to increase over the following ten years [4,5,9,12]. The risk increases with more severe traumatic brain injuries (STBIs) [6,13], with some reports suggesting an incidence as high as 40% [14].
