Internet Addiction becomes severe challenge in modern world due to excessive utilization of internet devices. Although it is not considered as a disease but it affects various domains of person’s social and academic activity and leads to poor quality of life. There are several scientific evidences regarding anatomical substrates in brain with reduced volume in persons with internet addiction but there is no still valid biomarker which could help clinician to perform precise diagnosis of this very challenging condition. We have studied 64 children with internet addiction (33 study group and 31 controls) where recording of evoked potentials was done. We have concluded that in internet addicted children and adolescents the late response of evoked potentials (P300) is changed. More precisely the amplitude is decreased and latency is increased. Thus alteration of parameters of P300 could be considered as a possible biomarker of internet addiction disorder.
