创伤后应激障碍（PTSD）是一种精神综合征，在暴露于可怕和危及生命的事件后发展，包括战争，机动车事故，身体和性侵犯。心理创伤的情感体验可能会产生长期的认知影响。创伤后应激障碍的标志性症状涉及认知过程的改变，如记忆，注意力，计划和解决问题，强调负面情绪对认知功能的有害影响。因此，PTSD研究人员和治疗提供者面临的一个重要挑战是了解情绪和认知之间的动态相互作用。PTSD的当代认知模型理论认为，信息处理资源的优势被分配给威胁检测和无害刺激作为威胁的解释，缩小了一个人的注意力集中在其他认知操作的代价。几十年的研究表明，使用各种任务和方法学方法支持这些PTSD的认知模型。本文就PTSD中情绪-认知相互作用的神经认知和神经影像学研究进展作一综述。为了直接评估情绪对认知的影响，反之亦然，这些研究回顾了包括认知和情绪成分的挑战任务。这些发现为创伤后应激障碍的记忆和注意力缺陷提供了证据，这些缺陷通常与大脑功能活动的变化有关。结果进行审查，以提供未来的研究方向，可能会直接更好，更有效的治疗创伤后应激障碍。
Posttraumatic stress disorder (PTSD) is a psychiatric syndrome that develops after exposure to terrifying and life-threatening events including warfare, motor-vehicle accidents, and physical and sexual assault. The emotional experience of psychological trauma can have long-term cognitive effects. The hallmark symptoms of PTSD involve alterations to cognitive processes such as memory, attention, planning, and problem solving, underscoring the detrimental impact that negative emotionality has on cognitive functioning. As such, an important challenge for PTSD researchers and treatment providers is to understand the dynamic interplay between emotion and cognition. Contemporary cognitive models of PTSD theorize that a preponderance of information processing resources are allocated toward threat detection and interpretation of innocuous stimuli as threatening, narrowing one's attentional focus at the expense of other cognitive operations. Decades of research have shown support for these cognitive models of PTSD using a variety of tasks and methodological approaches. The primary goal of this review is to summarize the latest neurocognitive and neuroimaging research of emotion-cognition interactions in PTSD. To directly assess the influence of emotion on cognition and vice versa, the studies reviewed employed challenge tasks that included both cognitive and emotional components. The findings provide evidence for memory and attention deficits in PTSD that are often associated with changes in functional brain activity. The results are reviewed to provide future directions for research that may direct better and more effective treatments for PTSD.
