惊厥(俗称抽风又名痉挛)是小儿疾病中常见的症状之一。婴幼儿时期较为多见,约5～10%的人在小儿时期曾患过惊厥,5岁以上比较少见。惊厥为中枢神经系统功能暂时紊乱而出现的一种综合征象,主要由于小儿时期大脑皮质神经细胞的细胞浆、细胞膜分化差,神经髓鞘形成尚未完全,神经细胞与神经胶质之间的正常关系尚未建立,抑制机制不健全,神经兴奋易于泛化所以容易 Convulsions, also known as convulsions, are one of the most common symptoms of pediatric disease. More common in infants and young children, about 5 to 10% of people who had had convulsions in infancy, more than 5 years old is rare. Convulsion as a temporary disorder of the central nervous system appears as a syndrome, mainly due to the cytoplasm of cerebral cortex neurons in infancy, poor cell membrane differentiation, neuromuscular formation is not yet complete, the normal relationship between nerve cells and glia Not yet established, inhibition mechanism is not perfect, easy to generalize nervous excitement so easy
