A study published Thursday in Science Daily has revealed that smartphone- and internet-addicted teenagers have significantly higher scores in depression, anxiety, insomnia severity and impulsiveness.
A research team led by Hyung Suk Seo, professor of neuroradiology at Korea University, used a scanning technique called magnetic resonance spectroscopy to evaluate the brains of 19 teenagers diagnosed with smartphone or internet addiction.
