| Summary: | Background: Young people spend a lot of time using Internet resources; therefore, they are most susceptible to Internet addiction (IA), in which the parameters of speed and accuracy of information processing by brain structures can change. The aim of the work was to evaluate the parameters of the auditory evoked potential P300 in young people aged 16-17 years with different risk levels of IA.
Methods and Results: A total of 46 healthy young people (14 boys and 32 girls, aged 16-17 years) living in Nadym city (Russia) took part in the study. Signs of IA were determined using the Chen Internet Addiction Scale (CIAS) in the Russian version of Malygin et al.(2011). The parameters of the auditory evoked potential P300 were evaluated using an electroencephalograph (Neuron-Spectrum-SM, Russia) using a standard auditory oddball paradigm. According to CIAS scores, two groups were identified: Group 1 (n=11/23.9% [6 boys, 5 girls]) with minimal IA risk, Group 2 (n=29/63% [8 boys, 21 girls]) with a moderate IA risk, and Group 3 (n=6/13.1% [all girls]) with a pronounced and stable IA pattern. Group 3 showed the lowest P300 latency in the temporal leads (F8, T4) on the right. Correlation analysis showed that the P300 latency in the F8 lead negatively correlates with the overall CIAS score (rS= -0.36, P=0.01).The persons of Group 2 had significantly higher P300 amplitude compared to Group 1 in the C3 (P1-2=0.010) and C4 (P1-2=0.013) leads. In Group 3, the P300 amplitude was significantly lower than in Groups 1 and 2 in the anterior temporal (F7 F8) and in frontal (F4) leads on the right (P3-1,3-2=0.010). Inverse correlations between the total CIAS score and the P300 amplitude were revealed in the F7 (r=-0.60, P=0.003), F8 (r=-0.70, P=0.001), F4 (r=- 0.71, P=0.001), and F3 (r=- 0.50, P=0.018) leads.
Conclusion: In young people, the severity of Internet-dependent behavior is associated with a decrease in the P300 latency in the right temporal lobe of the brain. Individuals with a moderate risk of IA showed a maximum amplitude of P300 in the central parts of the brain whereas individuals with signs of IA showed a minimal amplitude of P300 in the anterior temporal (F7 F8) and frontal (F4) regions on the right. The data obtained allow us to consider the revealed changes in the amplitude-time characteristics of the P300 in the temporal lobe of the brain as neurobiological markers of the risk of developing IA. |
