The neurobiology of smartphone addiction in emerging adults evaluated using brain morphometry and resting-state functional MRI

The characteristics of smartphone addiction (SPA) can be evaluated by neuroimaging studies. Information on the brain structural alterations, and effects psychosocial wellbeing, however, have not been concurrently evaluated. aim this study was to identify abnormalities in gray matter volume using voxel-based morphometry (VBM) neuronal functional alterations resting-state MRI (rs-fMRI) emerging adults with SPA. We correlated parameters indices for wellbeing such as depression, anxiety, stress, impulsivity. Forty participants (20 SPA 20 age-matched healthy controls) were assessed VBM rs-fMRI. scale – Malay version (SAS-M) questionnaire scores used categorize control groups. DASS-21 BIS-11 questionnaires assess impulsivity, respectively. identified group reduced insula precentral gyrus; increased grey precuneus relative controls. Moderate correlation observed between SAS-M scores. Individuals showed significant rs-fMRI activations precuneus, posterior cingulate cortex (FWE uncorrected, p<0.001). severity depression. Anxiety score moderately GMV at gyrus. Collectively, these results postulate that changes are linked neurobiology shares similarities other behavioural addictions.
