Abstract
This analysis explores how stimulant addictions—specifically cocaine, methamphetamines, and nicotine—impact the brain's reward system, comparing these effects with those seen in Internet Addiction (IA). Drawing from functional magnetic resonance imaging (fMRI) studies, it assesses changes in key brain regions involved in reward processing, craving, and cognitive control related to these addictive behaviors. The analysis investigates how each stimulant affects dopaminergic transmission and disrupts reward circuitry, highlighting both similarities and differences in brain activation patterns linked to addiction. By comparing these patterns with those seen in IA, the analysis aims to identify which stimulant most closely resembles the neural disruptions associated with IA. This will emphasize the need for further research on IA, particularly in distinguishing various subtypes beyond Internet Gaming Disorder (IGD) as addictions in the DSM-5, due to its impact on the brain’s reward system.
