Abstract
目的:探讨6~18岁高功能孤独症患者执行网络功能连接特点、年龄组差别及与孤独症症状的相关。方法:纳入44例6~18岁符合DSM-IV孤独症诊断标准的高功能患者及年龄、性别、智商组间匹配的31例正常对照,根据年龄将每组被试分为儿童期(6~12岁)和青春期(12~18岁)两组。选取左右侧后顶叶皮层及背外侧前额叶4个执行网络的核心脑区为种子点,计算其与全脑的功能连接。采用偏相关分析计算异常脑区功能连接与孤独症谱系障碍筛查问卷评分的相关。结果:孤独症组rdl PFC与左侧额上回/额中回/前扣带回的功能连接高于正常对照组(P <0. 05),该脑区功能连接同时呈现组别-年龄交互效应,在儿童期孤独症组高于正常对照组,在青春期低于正常对照组(均P <0. 05)。且该异常功能连接与重复刻板行为及交流问题呈负相关(r=-0. 50~-0. 45)(均P <0. 05)。结论:6~18岁高功能孤独症患者的执行网络存在过度连接特点及年龄组别差异,与重复刻板及交流症状相关
