摘要

Early exposure to social media-style digital content has become increasingly common among children and adolescents (0–21 years), with particular emphasis on early childhood, coinciding with a developmental period characterized by rapid brain growth, heightened neuroplasticity, and the maturation of attentional and executive control networks. This review synthesizes emerging epidemiological, cognitive-behavioral, and neurobiological evidence examining associations between early and intensive engagement with fast-paced, highly stimulating, reward-rich digital media and ADHD-related symptoms in the pediatric population. Epidemiological studies report small but statistically significant associations, with effect sizes that are modest and subject to substantial heterogeneity between greater screen or social-media exposure and later inattention, impulsivity, and executive dysfunction, with dose-response patterns strongest for problematic or addictive usage. Cognitive and behavioral findings indicate that rapid content switching, variable reward feedback, and media multitasking can disrupt sustained attention, working memory development, and inhibitory control. Neuroimaging and neurophysiological research further demonstrate overlapping mechanisms between ADHD neurobiology and digital-media reinforcement, including heightened ventral striatal activation, altered prefrontal functioning, and disrupted connectivity within attention and default-mode networks. These mechanisms may be moderated by sleep disruption, reduced opportunities for effortful attentional practice, and potential gene-environment interactions. Together, the evidence supports a developmental neurocognitive framework in which immature self-regulation systems may interact with highly stimulating digital environments in ways that are associated with ADHD-related behaviors. While causality cannot yet be inferred, the convergence of findings underscores the need for cautious media exposure in early childhood and highlights the importance of longitudinal, mechanistic research to clarify pathways, moderators, and targets for intervention.
