It is well-known that there is considerable variation in the effectiveness of evidence-based treatments for psychiatric disorders, and a continued need to improve the real-world effectiveness of these treatments. In the last 20+ years the examination of noninvasive brain stimulation techniques for psychiatric treatment has increased dramatically. However, in order to test these techniques for effective therapeutic use, it is critical to understand (a) (what are) the key neural circuits to engage for specific disorders or clusters of symptoms, and (b) (how) can these circuits be reached effectively using neurostimulation? Here we focus on the research toward the application of transcranial direct current stimulation (tDCS) for posttraumatic stress disorder (PTSD). tDCS is a portable and inexpensive technique that lends itself well to be combined with, and thus potentially augment, exposure-based treatment for PTSD. In this review, we discuss the behavioral model of threat and safety learning and memory as it relates to PTSD, the underlying neurobiology of PTSD, as well as the current understandings of tDCS action, including its limitations and opportunities. Through this lens, we summarize the research on the application of tDCS to modulated threat and safety learning and memory to date, and propose new directions for its future research.

经颅直流电刺激作为创伤后应激障碍的辅助治疗是否有基于神经科学的机械原理?

众所周知,基于证据的精神疾病治疗的有效性存在相当大的差异,并且需要继续提高这些治疗的真实效果。在过去的 20 多年里,对用于精神病学治疗的无创脑刺激技术的检查急剧增加。然而,为了测试这些技术的有效治疗用途,了解 (a)(什么是)参与特定疾病或症状群的关键神经回路,以及 (b)(如何)可以使这些回路成为关键使用神经刺激有效达到?在这里,我们重点研究经颅直流电刺激(tDCS)在创伤后应激障碍(PTSD)中的应用。tDCS 是一种便携式且廉价的技术,非常适合与 PTSD 的基于暴露的治疗相结合,从而有可能增强。在这篇综述中,我们讨论了与 PTSD 相关的威胁和安全学习和记忆的行为模型、PTSD 的潜在神经生物学,以及当前对 tDCS 作用的理解,包括其局限性和机遇。通过这个镜头,我们总结了迄今为止 tDCS 在调制威胁和安全学习和记忆中的应用研究,并为其未来的研究提出了新的方向。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。PTSD 的潜在神经生物学,以及目前对 tDCS 作用的理解,包括其局限性和机遇。通过这个镜头,我们总结了迄今为止 tDCS 在调制威胁和安全学习和记忆中的应用研究,并为其未来的研究提出了新的方向。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。PTSD 的潜在神经生物学,以及目前对 tDCS 作用的理解,包括其局限性和机遇。通过这个镜头,我们总结了迄今为止 tDCS 在调制威胁和安全学习和记忆中的应用研究,并为其未来的研究提出了新的方向。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。
