Digital addiction has emerged as a critical public health concern globally, characterized by compulsive and excessive use of digital devices and platforms that leads to significant impairment in various aspects of human functioning. This comprehensive review synthesizes current research on digital addiction, exploring its conceptual framework, neurobiological underpinnings, epidemiology, psychological impacts, and intervention strategies. Highlighting the parallels between digital addiction and substance use disorders, the review discusses brain reward system dysfunctions, autonomic nervous system involvement, and behavioral patterns that maintain addictive use.
