全球范围内的大型多人在线游戏 (MMO) 数量不断增加，其魅力也不断增加。当过度使用 MMO 而牺牲其他生活领域时，就会出现问题。尽管网络游戏障碍 (IGD) 尚未正式纳入常见诊断系统中，但在 DSM-5 第 III 节中被视为“需要进一步研究的病症”。本综述旨在概述目前 IGD 上可用的认知和神经生物学数据，特别关注冲动性、强迫性以及对奖励和惩罚的敏感性。此外，我们还将 IGD 的这些发现与病理性赌博 (PG) 的研究数据进行了比较——迄今为止，病理性赌博是 DSM-5 中唯一被正式归类为行为成瘾的病症。通过大脑功能和行为的改变来衡量，IGD 和 PG 的神经生物学存在多种相似之处。 IGD 患者和 PG 患者均表现出丢失敏感性下降；分别增强对游戏和赌博线索的反应；增强的冲动选择行为；基于奖励的异常学习；认知灵活性没有变化。 总之，基于游戏和赌博障碍的神经生物学的证据开始阐明两者之间的相似之处。然而，由于只有少数研究探讨了 IGD 的神经生物学基础，并且其中一些研究存在重大局限性，因此需要进行更多研究才能证明将 IGD 作为第二种行为成瘾纳入下一版本的 ICD 和 DSM 中。 (C) 2015 Elsevier Ltd. 保留所有权利。
The number of massively multiplayer online games (MMOs) is on the rise worldwide along with the fascination that they inspire. Problems occur when the use of MMOs becomes excessive at the expense of other life domains. Although not yet formally included as disorder in common diagnostic systems, internet gaming disorder (IGD) is considered a "condition for further study" in section III of the DSM-5. The current review aims to provide an overview of cognitive and neurobiological data currently available on IGD, with a particular focus on impulsivity, compulsivity, and sensitivity to reward and punishment. Additionally, we also compare these findings on IGD with data from studies on pathological gambling (PG)-so far the only condition officially classified as a behavioral addiction in the DSM-5.Multiple similarities have been observed in the neurobiology of IGD and PG, as measured by alterations in brain function and behavior. Both patients with IGD and those with PG exhibited decreased loss sensitivity; enhanced reactivity to gaming and gambling cues, respectively; enhanced impulsive choice behavior; aberrant reward based learning; and no changes in cognitive flexibility.In conclusion, the evidence base on the neurobiology of gaming and gambling disorders is beginning to illuminate the similarities between the two. However, as only a few studies have addressed the neurobiological basis of IGD, and some of these studies suffer from significant limitations, more research is required before IGD's inclusion as a second behavioral addiction in the next versions of the ICD and DSM can be justified.
