摘要 目的探讨创伤后应激障碍(PTSD)患者大脑局部一致性(ReHo)的变化。方法收集初次诊断的PTSD患者8例(PTSD组),经历创伤事件未发生PTSD者7例(非PTSD组),经历创伤事件第2周及3个月时进行血氧水平依赖性功能磁共振成像(BOLD-f MRI)检查,分析两组大脑不同功能区域的ReHo。结果与非PTSD组相比,PTSD组创伤事件后第2周ReHo降低的脑区有右侧舌回,未发现明显ReHo升高的脑区;第3个月ReHo降低的脑区有右侧颞中回、右侧枕叶、左侧颞下回,ReHo升高的脑区有左侧小脑、左侧额下回、左侧颞上回、左侧丘脑、右侧额上回(P均<0.05)。PTSD组创伤事件后第3个月较第2周左侧扣带回ReHo降低,右侧额叶眶回、右侧额下回、左侧额上回ReHo升高。结论 PTSD患者大脑皮质区存在ReHo变化,可能与局部功能连接改变有关。
