孤独症患儿婴儿时期的行为特征研究

目的：探讨孤独症患儿的早期特征性行为,为早期诊断提供依据。方法：采用回顾性调查方法对30例孤独症患儿及26例其他发育迟缓患儿在婴儿期的异常行为进行调查分析。结果：孤独症在婴儿时期以没有社交微笑、没有目光对视,对环境反应淡漠,很难用声音、动作或玩具吸引患儿的注意,叫其名字没有反应等症状明显区别于发育迟缓患儿(P<0.01);模仿、依恋行为差异有显著性(P<0.01或P<0.05);刻板动作及兴趣怪异仅见于孤独症患儿,但发生率较低。结论：孤独症在婴儿期即表现出许多特异性症状,表明孤独症多起病于生后早期,这些症状不同于其他智力发育迟缓患儿,对于孤独症的早期识别具有重要意义。
