Although the effects of transcranial direct current stimulation (tDCS) have been investigated for the treatment of addiction, it has not been evaluated for excessive online game use. This study aimed to investigate the feasibility and tolerability of tDCS over the dorsolateral prefrontal cortex (DLPFC) in online gamers.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec sec-type=\"methods\">\n          <jats:title>Methods<\/jats:title>\n          <jats:p>A total of 15 online gamers received 12 active tDCS sessions over the DLPFC (anodal left\/cathodal right, 2\u00a0mA for 30\u00a0min, 3 times per week for 4 weeks). Before and after tDCS sessions, all participants underwent <jats:sup>18<\/jats:sup>F-\ufb02uoro-2-deoxyglucose positron emission tomography scans and completed the Internet Addiction Test (IAT), Brief Self Control Scale (BSCS), and Beck Depression Inventory-II (BDI-II).<\/jats:p>\n        <\/jats:sec>\n        <jats:sec sec-type=\"results\">\n          <jats:title>Results<\/jats:title>\n          <jats:p>After tDCS sessions, weekly hours spent on games (<jats:italic>p<\/jats:italic>\u2009=\u2009.02) and scores of IAT (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) and BDI-II (<jats:italic>p<\/jats:italic>\u2009=\u2009.01) were decreased, whereas BSCS score was increased (<jats:italic>p<\/jats:italic>\u2009=\u2009.01). Increases in self-control were associated with decreases in both addiction severity (<jats:italic>p<\/jats:italic>\u2009=\u2009.002) and time spent on games (<jats:italic>p<\/jats:italic>\u2009=\u2009.02).
