Description
Summary:•We investigate brain function and structure in persons with “smartphone addiction” (SPA).•Persons with SPA showed lower gray matter volume in insula and temporal cortex.•Persons with SPA showed reduced resting-state activity of the anterior cingulate cortex.•Anterior cingulate cortex volume and activity was associated with SPA-severity.•The data suggest aberrant neural integrity of the salience network. Popularity and availability of smartphones have dramatically increased in the past years. This trend is accompanied by increased concerns regarding potentially adverse effects of excessive smartphone use, particularly with respect to physical and mental health. Recently, the term “smartphone addiction” (SPA) has been introduced to describe smartphone-related addictive behavior and associated physical and psychosocial impairment. Here, we used structural and functional magnetic resonance imaging (MRI) at 3 T to investigate gray matter volume (GMV) and intrinsic neural activity in individuals with SPA (n = 22) compared to a control group (n = 26). SPA was assessed using the Smartphone Addiction Inventory (SPAI), GMV was investigated by means of voxel-based morphometry, and intrinsic neural activity was measured by the amplitude of low frequency fluctuations (ALFF). Compared to controls, individuals with SPA showed lower GMV in left anterior insula, inferior temporal and parahippocampal cortex (p
