摘要

背景与目的:跨期和风险决策障碍是互联网使用障碍(IUD)的重要认知机制。然而,宫内节育器患者这两种决策功能障碍的潜在神经机制尚不清楚。方法:本研究采用功能近红外光谱(fNIRS)技术记录宫内节育器患者在颞间和风险决策任务时前额叶皮层血氧浓度的变化。结果:节育器组的颞间决策缺陷主要与左背外侧前额叶皮质(dlPFC)和眶额叶皮质(OFC)的激活减少有关,从左到右dlPFC。另一方面,风险决策障碍与OFC激活减少以及从左侧dlPFC到右侧dlPFC和OFC的功能连接减弱有关。讨论和结论:这些结果表明,尽管宫内节育器患者的颞间和风险决策障碍存在共同的神经机制,但每种类型的功能障碍都存在特定的神经基础。

Neural mechanisms of intertemporal and risky decision-making in individuals with internet use disorder: A perspective from directed functional connectivity.

Background and aims: The intertemporal and risk decision-making impairments are vital cognitive mechanisms in internet use disorder (IUD). However, the underlying neural mechanisms for these two decision-making dysfunctions in individuals with IUD remain unclear.

Methods: This study employed Functional Near-Infrared Spectroscopy (fNIRS) to record changes in blood oxygen concentration in the prefrontal cortex of individuals with IUD during intertemporal and risk decision-making tasks.

Results: The findings revealed that the intertemporal decision-making deficits in IUD group were primarily associated with reduced activation in the left dorsolateral prefrontal cortex (dlPFC) and orbitofrontal cortex (OFC) and FC from the left dlPFC to the right dlPFC. On the other hand, risk decision-making impairments were linked to decreased OFC activation and weakened functional connectivity from the left dlPFC to the right dlPFC and OFC.

Discussions and conslusions: These results suggested that while there were common neural mechanisms underlying intertemporal and risk decision-making impairments in individuals with IUD, specific neural foundations existed for each type of dysfunction.

期刊介绍: The aim of Journal of Behavioral Addictions is to create a forum for the scientific information exchange with regard to behavioral addictions. The journal is a broad focused interdisciplinary one that publishes manuscripts on different approaches of non-substance addictions, research reports focusing on the addictive patterns of various behaviors, especially disorders of the impulsive-compulsive spectrum, and also publishes reviews in these topics. Coverage ranges from genetic and neurobiological research through psychological and clinical psychiatric approaches to epidemiological, sociological and anthropological aspects.
