外伤性癫痫(traumatic epilepsy)指继发于颅脑损伤后的局限性或全身性痉挛,可分为早期癫痫(伤后1周内)和晚期癫痫(伤后1周到数年);其中早期癫痫中于伤后24小时内发作者称为即刻发作,伤后2~7天发作者称为近期发作或延迟发作。就病因而言,早期癫痫多与脑挫裂伤、凹陷性骨折、急性脑水肿、蛛网膜下腔出血和颅内血肿等有关,多属于暂时性发作;晚期癫痫多由脑-脑膜瘢痕、陈旧性凹陷性骨折压迫、脑脓肿、颅内异物、慢性硬膜下血肿等引起,多为持久性。
急性脑内血肿是外伤性癫痫(pte)的重要危险因素。

特点是脑挫伤处与着力处一致,外伤性癫痫灶的部位也是在着力点周围。
Brain injury is characterized at the Department and focus on the same site of traumatic epileptic focus is in the focus point around.
外伤性癫痫灶与其它的癫痫病灶不同的是由于癫痫灶比较局限,外科手术效果好。
