We examine whether children with early unilateral brain injury show an IQ decline over the course of development. Fifteen brain injured children were administered an IQ test once before age 7 and again several years later. Post-7 IQ scores were significantly lower than pre-7 IQ scores. In addition, pre-7 IQ scores were lower for children with larger lesions, but children with smaller lesions and higher pre-7 IQ scores showed a greater IQ decline over time. These findings suggest that the cognitive outcomes of children with early lesions, particularly those with relatively small lesions, change over the course of development.
我们研究早期单侧脑损伤儿童在发育过程中智商是否会下降。15名脑损伤儿童在7岁前接受了一次智商测试，几年后又进行了一次测试。7岁后的智商得分显著低于7岁前的智商得分。此外，损伤较大的儿童7岁前的智商得分较低，但损伤较小且7岁前智商得分较高的儿童随着时间推移智商下降幅度更大。这些发现表明，早期脑损伤儿童，尤其是那些损伤相对较小的儿童，其认知结果在发育过程中会发生变化。
