摘　　要：目的鉴于来我院就诊的苯丙酮尿症(PKU)患儿大部分都是延误治疗未经新生儿筛查的,他们都有不同程度的脑损伤,我们研究的目的是为了观察这些患儿治疗与学习情况的关连。方法我们对于1996年6月30日以前出生的 42例经典PKU患儿,皆用国产(北京)特殊营养食品治疗者,随访了入学、学习成绩的资料(包括2例新生儿筛查后即刻治疗)。结果 1．2例新生儿筛查后即刻治疗。学习成绩优秀,社会交往方面与正常孩子相同。2．儿童期诊断的经典 PKU 40例是在婴幼儿期或儿童期诊断的(未经新生儿筛查)入学31例(31／40,77．5％,包括推迟入学、不包括学前班和弱智学校),总入学率为77．50％。3．就学儿童的语文成绩均在中等以上,与开始治疗年量相关性较小,但对抽象思维影响很大,因此数学成绩较差。4．父母的文化程度、对治疗的依从性、家庭经济水平、家长与医生营养师、家长之间的交流对取得良好的治疗效果是非常重要的。结论早发现、早治疗,对预防苯丙酮尿症智力低下的发生是十分必要的,出生6 个月以后开始治疗的经典PKU患儿有一定效果,大部分可以就学。Objective： Since most of the PKU children visited our hospital were delay treated and didn＇t undergo newborn screening, so all of them had different degrees of cerebral damage.
