一个星期天的上午,我在门诊室遇到一位男病儿,圆而白的脸上长着一双大眼睛,看上去聪明可爱。可是,他的母亲却说这孩子是“小白痴”。这是怎么一回事呢?孩子的母亲向医生介绍了病儿的情况。这小男孩今年7岁,小名叫金金,他在婴儿时期生长发育与其他孩子没什么两样。1岁半开始讲话,口齿清楚,4岁前能自己端碗吃饭,能背诵简单的儿歌,还会数1～20的数,与同龄儿玩耍甚好。可在4岁后,金金渐渐地变得不听话,顽皮而好动,常发脾气,无故打人骂人并摔东西,话多而乱语。5岁后说话口齿不清,叫爸爸妈妈也不流利了,不会用语言来表达自己的要求。近一年来情况更不妙,不会说话,只是乱叫喊,基本丧失了语言能力。平日里行动冒然,不知危险,曾两次跌入水塘中,见到疾驰而来的汽车就往上扑。行为紊乱,拿凳子、棍子等物不停地在地上敲,还多次在吃饭时突然掀翻餐桌,摔饭碗,咬人抓人等。平时不知脏净,吃花生时连壳一起往嘴里塞。以前金金很会纠缠人,可现在变得不亲近父母,缺乏热情,并且不怕任何陌生人。睡眠明显减少,每晚只睡4～5小时。基于这些情况,家长带他来医院检查。在诊查室里,金金的两眼东张西望,对环境无陌 One Sunday morning, I met a male patient in the clinic, with a pair of big eyes on the round white face, looking smart and lovely. However, his mother said that this child is “idiot ”. What is going on? The child’s mother introduced the sick child to the doctor. The boy is 7 years old this year, his name is gold and gold, he grew up during infancy and other children are no different. One and a half years old began to speak, articulate, before 4 years old to eat their own bowls, can recite a simple children’s songs, but also the number of 1 to 20 the number of children playing very well with their peers. But after 4 years of age, the gold gradually become obedient, naughty and active, often temper, beating people for no reason hooligans and throwing things, then more and disorderly. After 5 years of age, his speech is not clear, so his father and mother are not fluent. They do not use language to express their own demands. In the past year, the situation is even worse. We can not speak but just shout and lose our language ability. Risky action on weekdays, I do not know the danger, had plunged into the pond twice, to see the car galloping from the upper body. Behavior disorder, take stools, sticks and other things constantly knocking on the ground, but also repeatedly overturned dinner table, throw bowl, bite arrest and so on. Usually do not know dirty, eat peanuts, even when the shell stuffed into the mouth. Gold and gold used to be entangled, but now they are not close to their parents, lack of enthusiasm, and are not afraid of any strangers. Significantly reduced sleep, sleep only 4 to 5 hours per night. Based on these circumstances, parents took him to the hospital for examination. In the examination room, gold and gold eyes looked around, no stranger to the environment
