摘要 目的:探讨局灶性癫痫患者的语言任务模式fMRI脑激活图,fMRI语言网络连接,分析语言功能与fMRI语言网络连接的联系。方法:选择18例符合诊断标准的局灶性癫痫患者(癫痫组)及18例健康志愿者(对照组),其中癫痫组完成以词语阅读任务为刺激模式的fMRI检查,以实现脑内相应功能区激活。利用SPM99软件进行分析,得出癫痫组与对照组fMRI的激活范围与信号变化,通过计算语言任务状态下fMRI最强激活区域时间过程相关性的信号变化,进行fMRI语言网络连接分析,采用独立样本t检验,比较癫痫组和对照组语言功能、fMRI语言网络连接的差异。结果:(1)局灶性癫痫患者fMRI语言激活图显示,激活强度和体积较健康组明显降低(P<0.01),(2)在词语阅读任务刺激下,癫痫组与对照组最强激活区域相互间fMRI语言网络连接比较,差异具有非常显著性(P<0.01)。结论:局灶性癫痫损害患者的语言功能,癫痫患者语言fMRI激活强度、体积较对照组明显降低,且在最强激活区内,癫痫患者的fMRI语言网络连接明显低于对照组,同时结果显示癫痫患者之间的语言偏侧化不明显,局灶性癫痫患者语言功能的损害与fMRI语言网络连接减少密切相关。
