摘要
创伤后应激障碍(PTSD)是由异常威胁性或灾难性事件导致的一类心理障碍,是21世纪迫切需要关注的公共卫生事件之一。探讨PTSD潜在的脑机制可为PTSD的早期干预、心理护理及追踪治疗提供理论基础。现有的研究从静息态和任务态两个方面对PTSD脑功能磁共振成像进行分析,结果表明PTSD患者的杏仁核反应增强、海马体积变小、前扣带回及内侧前额叶皮质反应减弱。未来的研究应关注控制组的选择,尤其是有无共病障碍的PTSD群体。
Post-traumatic stress disorder(PTSD)is a kind of psychological disorder caused by unusual threatening or catastrophic events,and it is one of the urgent public health events in the 21st century,which deserves more attention.Exploration of the underlying brain mechanisms of PTSD can provide theoretical basis for the early intervention,psychological nursing and follow-up treatment of PTSD.Current studies have analyzed PTSD brain functional magnetic resonance imaging at resting state and task state.The results showed that the amygdala response was enhanced in PTSD patients,and their hippocampal volume was reduced with decreased response of anterior cingulate cortex and medial prefrontal cortex.Future studies should attach greater importance to the selection of control group,with special focus on the presence of comorbidity.
