A study released Tuesday by the Journal of the American Medical Association suggests a direct relationship between computer screen time among teens and attention deficit hyperactivity disorder (ADHD).
The two-year study looked at a group of more than 2,500 high school students from Los Angeles whose ability to pay attention waned as they became increasingly involved in digital media platforms over the duration of the experiment, the Los Angeles Times reported.
For every notch a teens’ digital engagement rose, their reported ADHD symptoms rose by 10 percent, the study suggested. While significant digital media usage does not definitively cause ADHD, it does seem to induce symptoms that would warrant such a diagnoses or pharmaceutical treatment, the study said.
ADHD has long been thought to begin in the early stages of childhood development. But the exact circumstances – whether biological or brought on by one’s environment – are still debated among mental health professionals.
