Characteristic EEG Patterns in Individuals with Nonchemical Addiction

Abstract

A study was conducted to identify EEG patterns in various forms of nonchemical addiction (gaming and Internet addictions). When the game dependence is observed, the EEG is shifted towards high-amplitude waves, which indicates activation of the diencephalic synchronizing structures of the brain and corresponds to a neurotic state of the anxiety type. In the case of Internet addiction, the prevalence of the spectral characteristics of the β rhythm was detected, indicating an increase in the influence of the stem desynchronizing brain formations and a neurotic state of the stressed type. A characteristic feature of the EEG in both gaming and Internet addictions is the predominance of the functional activity of the right hemisphere.
