Neurobiological Consequences of Digital Burnout: A Meta-Analysis of Structural and Functional Brain Changes Associated with Constant Connectivity

Abstract

The extensive implementation of digital technology in contemporary life introduces the concept of digital burnout, which refers to continuous psychological exhaustion resulting from persistent digital connectivity. This meta-analysis integrates empirical evidence between the years 2000 and 2025 to observe the neurobiological basis of digital burnout through changes in structural and functional brain anatomy. Through a systematic review, 42 neuroimaging studies with a total of approximately 18,425 participants showed consistent patterns of neural reorganization. Principal findings include reduced gray matter volume in the prefrontal cortex, anterior cingulate cortex, and amygdala; diminished white matter integrity in tracts related to executive function and emotional regulation; altered functional connectivity within the default mode, salience, and reward networks; and dysregulation of dopaminergic and stress-response systems. Studies by Blix, Perski, Berglund, and Savic (2013) reported volumetric reductions in the caudate nucleus and putamen associated with chronic occupational stress, while Hutton, Dudley, Horowitz-Kraus, DeWitt, and Holland (2020) identified decreased white matter microstructural integrity in preschool children with elevated screen exposure. These neurobiological changes are associated with impaired attention span, executive dysfunction, emotional dysregulation, and heightened stress reactivity. A core assertion of the review is the bidirectional interaction between excessive technological use and neural adaptation, which suggests that long-term digital engagement may reshape brain architecture in such a way that it encourages further dependency and simultaneously diminishes cognitive control. Clinical intervention, educational policy, and strategies regarding digital wellness are discussed.
