Individuals with internet gaming disorder have similar neurocognitive impairments and social cognitive dysfunctions as methamphetamine-dependent patients.

This study aimed to examine whether individuals with Internet gaming disorder (IGD) have similar neurocognitive dysfunctions and social cognitive impairments as methamphetamine dependence (MD) patients. The participants included 30 individuals with IGD, 30 MD patients and 30 normal controls (NCs). All participants completed the digit span task, Iowa gambling task (IGT), WCST and the Interpersonal Perception Task-15 (IPT-15). The results showed that the IGD and MD groups had lower forwards and backwards scores, choices of advantageous minus disadvantageous decks, mean amount of money earned, number of categories completed, percentage of conceptual level responses, and IPT-15 total and factor scores compared with the NC group. Forwards and backwards scores, number of categories completed, percentage of conceptual level responses, choices from advantageous minus disadvantageous decks and mean amount of money earned were lower in the IGD group than in the MD group. The number of cards chosen from decks A, B, C, and D, total response errors, perseverative errors and failure to maintain set were higher in the IGD and MD groups than in NCs. Total response errors, perseverative errors and failure to maintain set were higher in the IGD than the MD group. The results revealed that neurocognitive deficits and social cognitive dysfunction in IGD are similar to those in MD. From a cognitive perspective, these results supported IGD as an addictive spectrum disorder and might lead to a bett...
