Computer game playing appears to be a very popular activity among Korean children and adolescents. Most parents and teachers are concerned about this situation because excessive computer game playing may result in academic and behavioral problems. However, there have been little scientific data supporting these concerns. The present study aims to identify patterns of possible psychobiological findings associated with behavioral addiction and excessive playing of computer games in adolescents. Six control and eight male adolescents with addiction to computer games were included. After recruited and screened by surveys for behavior addiction of computer games, all participants underwent psychiatric interviews, neuropsychological tests and other psychological measures before challenging computer games. Venous blood was obtained twice in each participant both during resting state and after twenty minutes’ playing computer game for measuring blood levels of biogenic amines and their metabolites.We could not find notable differences of psychological and neuropsychological functions in the addicted group, except for lowered vocabulary abilities. However, addicted adolescents revealed more robust increase of plasma NE, DA, 5-HT and some of their metabolites after twenty minutes’playing computer games, indicating altered sensitivity to computer games in this group. Present study suggests adolescents showing behavior addiction to computer games may be associated with altered psychobiological sensitivity to computer games. However, more replication studies and extended studies are crucial to generalize these findings.
