网络游戏障碍已被添加为DSM-V第三部分的研究诊断。神经科学研究的先前发现表明，对与计算机游戏相关的线索的动机性注意力增强，类似于物质相关成瘾的发现。另一方面，在临床观察性研究中，网络游戏障碍患者报告了耐受性效应。在本研究中，我们调查了网络游戏障碍患者是否存在增强的动机注意力或耐受性效应。从德国美因茨的行为成瘾门诊招募临床样本，符合互联网游戏障碍的诊断标准。在一个半自然的EEG设计中，参与者在记录事件相关电位的过程中玩电脑游戏，以评估奖励处理。结果表明，与健康对照组相比，网络游戏障碍患者在奖赏反应中P300减弱，N100潜伏期延长，波幅增加。我们的研究结果支持这一假设，即在积极玩电脑游戏时，网络游戏障碍患者存在耐受性效应。此外，最初的取向对游戏奖励的建议，消耗更多的能力与网络游戏障碍，这已经类似的其他研究与其他方法学背景的物质相关成瘾的疾病。
Internet Gaming Disorder has been added as a research diagnosis in section III for the DSM-V. Previous findings from neuroscientific research indicate an enhanced motivational attention toward cues related to computer games, similar to findings in substance-related addictions. On the other hand in clinical observational studies tolerance effects are reported by patients with Internet Gaming disorder. In the present study we investigated whether an enhanced motivational attention or tolerance effects are present in patients with Internet Gaming Disorder. A clinical sample from the Outpatient Clinic for Behavioral Addictions in Mainz, Germany was recruited, fulfilling the diagnostic criteria for Internet Gaming Disorder. In a semi-natural EEG design participants played a computer game during the recording of event-related potentials to assess reward processing. The results indicated an attenuated P300 for patients with Internet Gaming Disorder in response to rewards in comparison to healthy controls, while the latency of N100 was prolonged and the amplitude of N100 was increased. Our findings support the hypothesis that tolerance effects are present in patients with Internet Gaming Disorder, when actively playing computer games. In addition, the initial orienting toward the gaming reward is suggested to consume more capacity for patients with Internet Gaming Disorder, which has been similarly reported by other studies with other methodological background in disorders of substance-related addictions.
