Summary

Researchers are investigating whether brain connectivity and blood markers differ between adolescents with ADHD and healthy teens. The study includes 40 teens with ADHD and 40 matched controls, aged 10 to 18. Participants undergo brain imaging, blood tests, and assessments of executive function and emotional regulation. The goal is to see if these biological measures relate to the thinking and emotional challenges seen in ADHD.
