Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children aged 5-12 years with a primary diagnosis of ADHD who have not responded to standard sleep hygiene interventions.

Probably not a fit

Patients who have previously used weighted blankets or have significant comorbid conditions that affect adherence to the intervention may not benefit from this study.

What this trial studies

This clinical trial investigates the effects of weighted blankets on sleep disturbances in children aged 5-12 years diagnosed with ADHD. It employs a randomized controlled trial design, where participants are assigned to either receive a weighted blanket or a non-weighted sham blanket in addition to their usual treatment. The primary outcome measured will be the differences in total sleep time between the two groups. The study aims to provide evidence on the efficacy of weighted blankets in improving sleep quality for children with ADHD, addressing a significant issue that affects their overall well-being.

Why it matters

Potential benefit: If successful, this study could provide a non-pharmacological intervention to improve sleep quality in children with ADHD.

How similar studies have gone: While only one previous randomized controlled trial has investigated the effects of weighted blankets in children with ADHD, this study aims to expand on that limited evidence base.
