Table 1.
Subject demographics for adolescents with online gaming addiction (age range: 17–22 years) and control groups (age ranges: 17–21 years).
Figure 1.
Cortical thickness differences in adolescents with online gaming addiction compared with healthy controls.
After controlling for the Beck depression inventory-II (BDI) effect, increased cortical thickness was observed in several regions in late adolescence with online gaming addiction compared to healthy controls, i.e. the left precentral cortex, precuneus, middle frontal cortex, and inferior temporal and middle temporal cortices. In addition, reduced cortical thickness in the left lateral orbitofrontal cortex (OFC), insula cortex and lingual gyrus, along with the right postcentral gyrus, entorhinal cortex, and inferior parietal cortex were detected in late adolescence with online gaming addiction.
Figure 2.
Correlation analysis results between cortical thickness and duration of online gaming addiction in late adolescence with online gaming addiction.
The cortical thicknesses of the peak vertex within the clusters of the left precentral cortex (r = 0.7902, p = 0.0001) and precuneus (r = 0.7729, p = 0.0002) were found to be significantly positive correlated with the duration of online gaming addiction in late adolescence with online gaming addiction. The left lingual gyrus (r = −0.8102, p<0.0001) showed significantly negative correlation with the duration of online gaming addiction.
Figure 3.
Correlation analysis results between cortical thickness and stroop task performances in adolescents with online gaming addiction.
The cortical thickness of the peak vertex in the left orbitofrontal cortex (OFC) was significantly correlated with the number of errors during the incongruent condition among late adolescence with online gaming addiction (r = −0.5580, p = 0.0161).
