Nature :缺乏眼神交流或是婴儿自闭症表现

2013-11-14 科学网 科学网

和同龄人相比,自闭症儿童的眼神交流更少——这一指标通常用来诊断两岁后的幼儿是否患有发展性障碍。但是近日《自然》杂志发表的一篇论文报告,婴儿早在两个月大时就可以表现出自闭症迹象,这是最早能探测出自闭症症状的阶段。【原文下载】 如果该研究能够应用于更大规模的人群中,在婴儿中进行自闭症诊断将成为可能,进而可以早发现早治疗,美国乔治亚州亚特兰大市马库斯自闭症中心研究主管Warren Jones说。

如果该研究能够应用于更大规模的人群中,在婴儿中进行自闭症诊断将成为可能,进而可以早发现早治疗,美国乔治亚州亚特兰大市马库斯自闭症中心研究主管Warren Jones说。

Jones和同事Ami Klin选定了110名婴儿作为研究对象,自他们出生起进行观察——其中59人患自闭症的风险更大,因为他们有一个兄弟或姐妹是自闭症患者;另外51人患病几率较小。

根据亚特兰大市美国疾病控制和预防中心最近的调查结果,每88个儿童中,就有一人患有自闭症谱系障碍(ASD)。

“婴儿初到这个世界时,会有强烈的倾向进行眼神交流。相较于脸的其他部位,他们更喜欢盯着人的眼睛看。”Jones说。

英国剑桥大学自闭症研究人员Simon Baron-Cohen说,这项新研究是意义非凡的,使得自闭症早期发现和早期干预成为可能。

Jones表示,现在利用自己团队的发现来诊断自闭症还为时过早,还需要在更广泛的人群中开展实验。“这是我们在未来的长期目标。”他说。
