Biol Psychiatry:边缘性人格障碍的神经干扰性处理

2015-12-14 candy 译 MedSci原创

背景:情绪加工和处理上的焦虑和不安是边缘性人格(BPD)的特征。为了进一步阐明BPD的神经基础,meta分析总结目前为止的有关情绪加工中功能性神经影像学研究的发现,同样的,还有结构性神经影像学研究发现,和多途径影响大脑区域的研究。方法:联合以坐标和图像为基础的meta分析,利用不用微分映射标记的各向异性效应大小进行计算。19个功能性神经影响学研究调查比较消积情绪处理与中性刺激,总共涉及281例BP

背景:情绪加工以及处理上的焦虑和不安是边缘性人格障碍(BPD)的特征。为了进一步阐明BPD的神经基础,meta分析总结目前为止的有关情绪加工中功能性神经影像学研究的发现,同样的,还有结构性神经影像学研究发现,和多途径影响大脑区域的研究。

方法:联合以坐标和图像为基础的meta分析,利用不用微分映射标记的各向异性效应大小进行计算。19个功能性神经影响学研究调查比较消积情绪处理与中性刺激,总共涉及281例BPD患者和293例健康对照组(HC)。另外,10项研究对263例BPD患者和278例HC进行分析,调查灰质异常情况。

结果:在处理消极情绪刺激时,相对对照组,显示BPD患者的左侧杏仁核和扣带回后部的激活是有所增加的,伴双侧背外侧前额叶皮层反应的减弱。多模态分析证实BPD较HC有左杏仁核功能愈加亢进和灰质体积更小的特点。杏仁核的高响应率因病患组的用药状况得到缓和。无用药组的特点是边缘性极度活跃,另外发现是否近期服用精神药物的组间无差异。

结论:结果证实了边缘性人格障碍病患的特征为拥有不正常的背外侧前额叶和大脑边缘区域,因此与BPD作为情绪失调疾病的概念是一致的。
