Summary

This study looks at how sleep, physical activity, and daily rhythms relate to ADHD symptoms and brain function in 200 children. Kids wear a wristband for two weeks and complete cognitive tests and MRI scans. The goal is to better understand why ADHD affects people differently and to improve future assessments.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could improve how ADHD is assessed and managed by linking daily patterns like sleep and activity to specific symptoms.
What could go wrong
This is an observational study with no treatment, so it won't directly change care. Results may not apply to all children with ADHD.

This is an AI summary of the original study and may miss details. Read our disclaimer.

An estimate. End dates often move.
