Correlation between smartphone addiction and psychosocial factors among students and assessment of fMRI brain activation in response to reward

Smartphone-based Instagram addiction is an emerging digital addiction and is of mental, physical and social concern among the young university students. Functional magnetic resonance imaging (fMRI) is a non-invasive neuroimaging technique that utilises Blood Oxygen Level Dependent imaging to d...

In Phase 2 study, a case-control study using fMRI as a non-invasive biomarker was conducted to identify the regional brain activation in the mesocorticolimbic system during a cue-induced reactivity task among the randomly selected cohort of subjects (addicted n=15, control n=15). This study detected problematic smartphone usage among 60.7% of young undergraduate students in UPM and PIGU was significantly correlated with psychosocial problems (p<0.05). Left Precuneus was significantly activated in the addicted group (pFWE<0.05) and the percentage signal change in right medial prefrontal cortex and right anterior cingulate cortex were significantly correlated with addiction (p<0.05). fMRI is able to non-invasively identify the regions of brain activation in response to the addictive stimulus in the reward system and this study is able to achieve a milestone by providing evidence to support the theories of development of ‘tolerance’ among the SPA individuals.
