How sleep, physical activity, and circadian rhythms relate to different ADHD symptoms.

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants will wear a wristband to record continuous sleep and activity data alongside brief momentary assessments and a battery of cognitive tasks (Go/No‑Go, Stop Signal, Delay Discounting, Mirror Tracing, Spatial Span). The study enrolls a clinical ADHD group meeting DSM‑5 criteria and a control group without neurodevelopmental or psychological diagnoses, with exclusions for prematurity, prenatal substance exposure, traumatic brain injury, certain co-occurring disorders, and certain medications. Researchers will analyze 24‑hour rest/activity rhythms, sleep disturbances, and daytime activity metrics in relation to attention, impulsivity, emotion dysregulation, and related behavioral and neural measures. The aim is to identify objective sleep/activity markers that map onto different ADHD symptom profiles to inform better assessment and targeted interventions.
