J Autism Dev Disord:脑波测试或改善自闭症诊断与分类

2014-09-29 伊文 EurekAlert中文

由美国叶史瓦大学阿尔伯特·爱因斯坦医学院的科研人员进行的一项新研究提示,测量大脑对景象和声音的反应速度可能有助于客观地对患有自闭症谱系障碍(ASD)的人们进行分类,而且可能有助于更早地诊断这种疾病。这篇论文今天在线发表在了《自闭症与发育障碍杂志》(Journal of Autism and Developmental Disabilities)上。 美国疾病控制与预防中心估计,每68名儿

由美国叶史瓦大学阿尔伯特·爱因斯坦医学院的科研人员进行的一项新研究提示,测量大脑对景象和声音的反应速度可能有助于客观地对患有自闭症谱系障碍ASD)的人们进行分类,而且可能有助于更早地诊断这种疾病。这篇论文今天在线发表在了《自闭症与发育障碍杂志》(Journal of Autism and Developmental Disabilities)上。

美国疾病控制与预防中心估计,每68名儿童就有1名已经被识别为自闭症谱系障碍。自闭症谱系障碍的体征与症状在人与人之间有很大不同,范围从轻微的社会与交流困难到显著的认知削弱。

“自闭症的挑战之一就是我们不知道如何把患者归类为亚群,或者甚至不知道这些亚群究竟是什么,”领导了该研究的阿尔伯特·爱因斯坦医学院Dominick P. Purpura神经科学系副教授、儿科学系的Muriel 与Harold Block精神疾病教员学者Sophie Molholm博士说。“这已经极大地限制了我们对这种疾病的理解,也限制了治疗它的方法。”

自闭症是根据患者的行为特征与症状加以诊断的。“这些评估可能是高度主观的,需要大量的临床专家技能,” Molholm博士说。“我们明显需要一个更加客观的方法去诊断和归类这种疾病。”

Molholm博士和她的同事之前的一项研究提示,脑电图(EEG)记录有可能揭示出自闭症谱系障碍(ASD)个体受到了多严重的影响。那项研究发现,患有自闭症谱系障碍(ASD)的儿童处理感觉信息——诸如声音、触摸与视觉——比典型发育中的儿童较慢。

当前的这项研究的目的是发现自闭症谱系之间的是否有感觉处理的差异。向43名6到17岁的自闭症谱系障碍(ASD)儿童呈现了一个简单的音调、一个视觉图像(红圈)或者一个音调与一个图像的组合,要求他们在听到这个音调、看到这个图像或者同时看到和听到这两个刺激的时候尽快地按一个按钮。通过70个头皮电极记录了连续的脑电图,从而确定这些儿童的大脑处理这些刺激的速度。

这些受试者处理听觉信号的的速度与他们的症状的严重程度强烈相关:一名自闭症谱系障碍(ASD)个体处理这种听觉信号需要的时间越多,这个人的自闭症症状也就越严重。“这项发现符合另一些研究,那些研究表明,患自闭症谱系障碍(ASD)的人们的大脑听觉中心的微结构与典型发育中的儿童不同,” Molholm博士说。

这项研究还发现了听觉-视觉信号组合的处理速度与自闭症谱系障碍(ASD)严重性之间的一个显著但是更弱的相关性。没有观察到视觉处理与自闭症谱系障碍(ASD)严重性之间存在联系。

“这是朝着开发出自闭症严重性的生物标记——这是评价一个人在自闭症谱系障碍谱上的位置的一种客观方法——迈出的第一步,” Molholm博士说。“用这类方法使用脑电图记录还有可能对于客观评价自闭症谱系障碍(ASD)疗法的有效性有用。”此外,脑电图记录可能帮助更早地诊断自闭症谱系障碍(ASD)。“早期诊断可以带来更早的治疗——我们知道这会增加更好的结果的可能性,” Molholm博士说。“但是目前,不到15%的自闭症谱系障碍(ASD)儿童是在4岁之前被诊断的。我们可能有能力采用这种技术从而为远远更大比例的儿童带来早期自闭症谱系障碍(ASD)检测和疗法。”

这篇论文的题目是《非典型听觉处理与多感官整合的神经生理学指数与自闭症症状严重性有关联》。
