NCT ID NCT06221358

First seen Jan 06, 2026 · Last updated Jun 22, 2026 · Updated 28 times

Summary

This study explores how genetics influence how children and teens with ADHD respond to the stimulant methylphenidate. Researchers will analyze DNA from 400 participants aged 6-24 in Western Canada to see if certain genes are linked to better symptom control or fewer side effects. The goal is to make ADHD treatment more personalized and effective.
