NCT ID NCT05368493

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study looks at whether air pollution exposure before birth is linked to ADHD risk in Puerto Rican children. Researchers will use brain scans (MRI) in 182 kids aged 6-11 to examine brain areas tied to attention. They also want to see if inflammation during pregnancy or sleep problems in childhood play a role. The goal is to find early, changeable factors that could help prevent ADHD.
