高热惊厥是小儿常见的疾病,5岁以下小儿的发病率约为2～3％,甚至有的作者提出,约5～8％的小儿有高热惊厥。除了发病数较高之外,高热惊厥对小儿的危害性也渐被重视。过去曾将高热惊厥比作成人发热前的寒战,认为无关紧要。后来证明,惊厥本身可造成缺氧性脑损伤,同时也发现,高热惊厥与癫痫的关系甚为密切,因而高热惊厥已被广泛重视,目前,基于较长期的临床和实验室研究,对于高热惊厥的临床分型、诊断标准、预后、与癫痫的联系、及其对脑组 Convulsive fever is a common disease in children, the incidence of children under 5 years of age is about 2 to 3%, and some authors even suggested that about 5 to 8% of children have febrile seizures. In addition to the higher incidence of fever, febrile seizures on the dangers of children have gradually been taken seriously. In the past, febrile seizures than before the chills of adults before fever, that does not matter. Later proved that convulsions can cause hypoxic brain injury itself, but also found that the relationship between febrile seizures and epilepsy is very close, so the febrile seizures have been widely valued, at present, based on longer-term clinical and laboratory studies for febrile seizures The clinical classification, diagnostic criteria, prognosis, and epilepsy, and its brain group
