摘 要:目的检测高同质性男性抑郁症患者注意控制相关脑区功能动态变化的情况。方法利用脑磁图检测12例单相复发男性抑郁症患者,以及12名年龄、受教育年限近似匹配的男性健康对照者完成Stroop字色干扰测试任务时脑功能的改变。结果将0~1000ms时间段按先后顺序每100ms显示男性患者激活异常脑区,其中激活显著减弱的脑区有:左中央后回(t=3.10)、右额上回(t=2.16)、左额中回(t=2.64)、左顶叶(t=2.89)、右颞中回(t=1.92)、右颞上回(t=2.84)、右脑岛(t=3.03)、右楔前叶(t=2.98)、双侧额中回(t=3.64,t=2.25)、右中央后回(t=2.20)、右扣带回(t=4.04)、双侧楔前叶(t=2.79,t=1.87);激活显著增高的脑区有:左尾状核体(t=2.21)、左脑岛(t=2.31)、左丘脑枕(t=2.36)、左尾状核体(t=1.91)、左丘脑枕(t=2.56)、左颞中回(t=1.89)、左中央前回(t=2.02)。设P〈0.05时,差异具有统计学意义。结论男性单相复发抑郁症患者完成Stroop字色干扰测试任务时参与注意控制加工的脑区功能较正常人存在异常,加工时程中呈现皮层减弱、边缘系统增强的功能分离状态。Objective To study information transmission circumstances within the neural circuits related to the attentional controls of the male depression patients. Methods Twelve unipolar depression patients and twelve age- and educationmatched healthy controls were involved in the Stroop word-color interference test to detect the variation of brain inhibitory function by Magnetoencephalography scanning. Results Compared with the healthy controls, the abnormally activities in depressed patients during in chronological order were separately as follow: decreased activation in the left postcentral gyms ( t = 3.10 ), the right superior frontal gyrus ( t = 2.16 ) , the left middle frontal gyrus ( t = 2.64 ), the left parietal lobe ( t = 2.89 ), the right middle temporal gyrus ( t = 1.92 ), the right superior temporal gyrus ( t = 2.84), the right insula( t= 3.03 ), the right precuneus ( t= 2.98 ), the bilat- eral middle frontal gyrus ( t = 3.64, t = 2.25 ), the right postcentral gyrus ( t = 2.20 ), the right cingulate gyrus ( t = 4.04 ) , the bilateral precuneus ( t = 2.79, t = 1.87 ) ; increased activation in the left caudate body ( t = 1.91 ) , the left pulvinar( t = 2.56 ), the left middle temporal gyrus ( t = 1.89), the left precentral gyrus ( t = 2.02 ) (P 〈 0.05, uncorrected). Conclusion The abnormal activation in the brain regions related with attentional control processing is detected in the male recurrent unipolar recurrent major depression, performances of limbic system increased and. cortex declined more in the recurrent depressed.
