  • Screen time is associated with increased ADHD symptoms and reduced cortical thickness in specific brain regions.
  • The study used data from the ABCD study, analyzing 10,116 children at baseline and 7,880 at a two-year follow-up.
  • Screen time was linked to reduced cortical thickness in the right temporal pole, left superior frontal gyrus, and left rostral middle frontal gyrus.
  • Total cortical volume partially mediated the relationship between screen time and ADHD symptoms at baseline.
  • The findings suggest that longer screen time may contribute to ADHD symptoms and altered brain development.
  • The study highlights the potential neural mechanisms underlying the association between screen time and ADHD.
