根据发病部位的不同,可将小儿惊厥的发病原因分为两类:颅内疾病和颅外疾病所导致的惊厥。(如下表)其中,流感、细菌性痢疾、肠道病毒感染等感染性疾病引起的突发高热,是6个月～3岁小儿最常见的惊厥原因。一般为全身性,次数少,时间短,恢复快,通常不会造成后遗症。 According to the different parts of the disease, the incidence of pediatric convulsions can be divided into two categories: intracranial disease and extracranial disease caused by convulsions. (Table 1 below) Among them, the sudden onset of fever caused by infectious diseases such as influenza, bacillary dysentery and enterovirus infection is the most common cause of seizures in children aged 6 months to 3 years. Generally systemic, less frequent, shorter time, faster recovery, usually does not cause sequelae.
