Abstract

Given the well-documented association between emotion regulation (ER) deficits and suicidal thoughts and behaviors (STBs), and the limited understanding of their neural mechanisms, we reviewed studies across five databases that included validated ER tasks and neuroimaging techniques such as functional magnetic resonance imaging and electroencephalography. This systematic review synthesizes evidence from 11 neuroimaging studies to explore the neural correlates of ER deficits in individuals with STBs. Findings revealed that individuals with STBs exhibit heightened activation in the dorsolateral and ventrolateral prefrontal cortex during ER tasks, alongside increased amygdala reactivity to negative stimuli (e.g., sad facial expressions), in implicit ER paradigms. Heterogeneity in prefrontal cortex activation suggests that task- and population-specific neural signatures may influence these patterns. Our review also identifies methodological limitations in the current literature, including a reliance on cross-sectional designs and small sample sizes, which limit generalizability. These limitations highlight the need for longitudinal and multi-modal studies to better understand the dynamic neural patterns associated with ER and STBs. By elucidating the neural underpinnings of ER deficits in STBs, these findings may enable earlier identification of at-risk individuals and the development of personalized, targeted interventions (e.g., transcranial magnetic stimulation).

情绪调节行为指标与自杀念头和行为的神经关联。
鉴于情绪调节(ER)缺陷与自杀想法和行为(STBs)之间的关联已被充分证明,而对其神经机制的了解有限,我们回顾了五个数据库中的研究,包括经过验证的ER任务和功能磁共振成像和脑电图等神经成像技术。本系统综述综合了11项神经影像学研究的证据,以探讨性传播感染患者内质网缺损的神经相关性。研究结果显示,在内啡肽任务中,STBs个体的背外侧和腹外侧前额叶皮层的激活增强,同时,在内隐内啡肽范式中,杏仁核对负面刺激(如悲伤的面部表情)的反应增强。前额皮质激活的异质性表明,特定任务和群体的神经特征可能会影响这些模式。我们的综述还指出了当前文献中方法上的局限性,包括对横断面设计和小样本量的依赖,这限制了通用性。这些局限性突出了纵向和多模态研究的必要性,以更好地了解与内窥线和stb相关的动态神经模式。通过阐明性传播疾病内质网缺损的神经基础,这些发现可能有助于更早地识别高危个体,并开发个性化的、有针对性的干预措施(例如,经颅磁刺激)。

期刊介绍: Archives of Suicide Research, the official journal of the International Academy of Suicide Research (IASR), is the international journal in the field of suicidology. The journal features original, refereed contributions on the study of suicide, suicidal behavior, its causes and effects, and techniques for prevention. The journal incorporates research-based and theoretical articles contributed by a diverse range of authors interested in investigating the biological, pharmacological, psychiatric, psychological, and sociological aspects of suicide.
