生活中常有这样的情况发生:一个好端端的孩子,长到几岁上,突然发现有某些生理、心理上的缺陷。刚发现,但治疗却已晚了。这种情况的出现,是因为婴儿时期的某些生理、心理缺陷不易被察觉,往往要等到孩子长大一些才能显现。对于这些疾病和智能障碍,早发现、早治疗以及早进行特殊训练是至关重要的。过了一定年龄,就丧失了治疗的机会。 This is often the case in life: a good-looking child, how old, suddenly found some physical and psychological defects. Just discovered, but the treatment is too late. This situation arises because some of the physical and psychological defects in infancy are not easily detected and often do not appear until the child has grown older. For these diseases and mental retardation, early detection, early treatment and early training is crucial. After a certain age, they lose the chance of treatment.
