Brief:
OBJECTIVE: To observe the therapeutic effects of electro-acupuncture (EA) combined with psychological intervention on the symptom of somzatization or obsession and mental symptom of depression or anxiety and P50 of Auditory Evoked Potential (AEP) on internet addiction disorder (IAD). METHODS: One hundred and twenty cases of IAD were randomly divided into an EA group, a psycho-intervention (PI) group and a comprehensive therapy (EA plus PI) group. Patients in the EA group were treated with EA. Patients in the PI group were treated with cognition and behavior therapy. Patients in the EA plus PI group were treated with electro-acupuncture plus psychological intervention. Scores of IAD, scores of the symptom checklist 90 (SCL-90), latency and amplitude of P50 of AEP were measured before and after treatment. RESULTS: The scores of IAD after treatment significantly decreased in all groups (P < 0.05), and the scores of IAD in the EA plus PI group were significantly lower than those in the other two groups (P < 0.05). The scores of SCL-90 assembled and each factor after treatment in the EA plus PI group significantly decreased (P < 0.05). After treatment in the EA plus PI group, the amplitude distance of S1P50 and S2P50 (S1-S2) significantly increased (P < 0.05). CONCLUSION: EA combined with PI could relieve the mental symptoms of IAD patients, and the mechanism is possibly related to the increase of cerebrum sense perception gating function.
