癲癇發作(epileptic seizure 或epileptic fit,有時在文獻或新聞簡稱 seizure 或fit) 是由於大腦中神經元活動異常過度或同步導致的症狀[1][2]。 這種腦內異常的外溢效應(outward effect)可以是無法自行控制的混亂運動;也可以是短暫的失去意識。只要是有任何能引起癲癇發作(epileptic seizures)的腦部疾病,統稱為癲癇(epilepsy)。[1][3]
癲癇發作可能發生在沒有癲癇歷史的人身上。危險因子包括:腦部受創(brain trauma)、濫用藥物[4]、過高體溫、低血糖 和缺氧。另外有一些看起來像癲癇發作的症狀,但實際上並非真的癲癇發作。
首次出現的癲癇發作通常不需要長時間服用抗癲癇藥,除非出現特定問題或要照腦電圖或腦部造影(brain imaging)[5]。
所有活到80歲的人之中大約5~10%,在其人生中至少遇過一次癲癇發作,遇到第二次癲癇發作的機率介於40~50%之間。 [5][6]

癲癇發作的征狀和症狀依照其類型而定[7]。 最常見的癲癇發作是驚厥 (60%)[8]。
