摘要

背景:全球范围内,自杀对个人、家庭和社会都有深远的影响,因此迫切需要有效的早期发现和预防策略。本系统综述旨在调查事件相关电位(erp)作为识别和监测自杀风险的工具的使用。方法:进行全面的文献检索,纳入23篇符合入选标准的文献。该综述综合了与自杀风险相关的各种ERP成分的研究结果。结果:分析显示,与健康对照组相比,有自杀史的个体在去/不去范式下对新刺激的P3波幅反应显著降低[标准化平均差(SMD) = -0.53, 95%置信区间(CI) = -0.96;-0.10]]。此外,对奖励积极反馈的P3反应的改变表明有风险的人存在损伤(SMD = -1.12, 95% CI = -1.74;-0.49])。其他ERP组成部分的可变性也被强调,有几个调节因素,如样本特征和方法设计,影响ERP组成部分。结论:研究结果表明,特定的ERP成分,特别是P3,可能是评估自杀风险的有价值的指标。这篇综述强调了未来的研究需要利用更大、更均匀的样品和先进的分析技术来提高检测精度。erp的应用被认为是提高对与自杀风险相关的神经认知机制的理解和加强预防工作的有希望的途径。

Detection of suicide risk using event-related potentials: a comprehensive systematic review and meta-analysis.

Background: Suicide has profound effects on individuals, families, and societies globally, underscoring the urgent need for effective early detection and prevention strategies. This systematic review aims to investigate the use of event-related potentials (ERPs) as a tool for identifying and monitoring suicide risk.

Methods: A comprehensive literature search was conducted, resulting in the inclusion of 23 articles that met the eligibility criteria. The review synthesized findings related to various ERP components associated with suicide risk.

Results: The analysis revealed that individuals with a history of suicide risk exhibited significantly reduced P3 amplitudes in response to novel stimuli during the go/no-go paradigm compared to healthy controls [standardized mean difference (SMD) = -0.53, 95% confidence interval (CI) = [-0.96; -0.10]]. Additionally, altered P3 responses to positive feedback on rewards indicated impairments in those at risk (SMD = -1.12, 95% CI = [-1.74; -0.49]). Variability in other ERP components was also highlighted, with several moderators, such as sample characteristics and methodological design, influencing ERP components.

Conclusion: The findings suggest that specific ERP components, particularly the P3, may serve as valuable indicators for assessing suicide risk. The review emphasizes the need for future research to utilize larger, more homogeneous samples and advanced analytical techniques to enhance detection accuracy. The application of ERPs is posited as a promising avenue for improving understanding of the neurocognitive mechanisms associated with suicide risk and enhancing prevention efforts.
