【摘要】:目的:探讨6~18岁高功能孤独症患者的灰质体积异常脑区以及异常脑区发育特点。方法:纳入19例6~18岁符合美国精神障碍诊断与统计手册第4版孤独症诊断标准且总智商≥70的高功能孤独症患者,以及年龄、总智商、性别组间匹配的16例正常对照,以磁共振成像检查收集被试的脑影像学资料,采用基于体素的形态学测量方法计算两组被试大脑各区域的灰质体积,在统计学参数图(SPM)软件SPM8中进行双样本t检验得出差异脑区,对结果进行错误率(FDR)多重比较校正(P0.05)。采用偏相关分析两组被试差异脑区灰质体积与年龄的相关性。结果:高功能孤独症组的右侧额下回眶额部灰质体积小于正常对照组(FDR校正,P0.05)。正常对照组右侧额下回眶额部灰质体积与年龄呈负相关(r=-0.592,P0.05),高功能孤独症患者右侧额下回眶额部灰质体积与年龄呈负相关(r=-0.696,P0.01)。结论:与正常人相比,6~18岁高功能孤独症患者右侧额下回眶额部发育异常,此脑区可能参与孤独症的病理机制。
