Methods： Thirty-two IA adolescents were allocated to either EA（16 cases） or PI（16 cases） group by a randomized digital table. Subjects in the EA group received EA treatment and subjects in the PI group received cognition and behavior therapy. All adolescents underwent 45-d intervention. Sixteen healthy volunteers were recruited into a control group. Barratt Impulsiveness Scale（BIS-11） scores, Young＇s Internet Addiction Test（IAT） as well as the ratio of brain N-acetyl aspartate（NAA） to creatine（NAA/Cr） and choline（Cho） to creatine（Cho/Cr） were recorded by magnetic resonance spectroscopy before and after intervention respectively. Results： The IAT scores and BIS-11 total scores in both EA and PI group were remarkably decreased after treatment（P〈0.05）, while EA group showed more significant decrease in certain BIS-11 sub-factors（P〈0.05）. Both NAA/Cr and Cho/Cr were significantly improved in EA group after treatment（P〈0.05）; however, there were no significant changes of NAA/Cr or Cho/Cr in PI group after treatment（P〉0.05）. Conclusions： Both EA and PI had significantly positive effect on IA adolescents, especially in the aspects of psychological experiences and behavioral expressions, EA might have an advantage over PI in terms of impulsivity control and brain neuron protection. The mechanism underlying this advantage might be related to the increased NAA and Cho levels in prefrontal and anterior cingulate cortices.展开更多
