What this trial studies

This trial evaluates the feasibility of using the Monarch external trigeminal nerve stimulation (eTNS) device as a non-pharmacological treatment for children and adolescents aged 7 to 17 years diagnosed with ADHD. Participants will be randomly assigned to receive either the active eTNS device or a sham device for four weeks during nighttime. Throughout the trial, families will complete questionnaires and maintain logbooks to track their experiences and symptoms. The study aims to assess treatment compliance, completion rates, and gather feedback from families to determine the potential for a larger clinical trial.

Who should consider this trial

Good fit: Ideal candidates are children and adolescents aged 7 to 17 years with a clinical diagnosis of ADHD.

Not a fit: Patients currently receiving atomoxetine or guanfacine, or those with epilepsy or electronic/metallic implants, will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a non-invasive treatment option for children with ADHD, reducing reliance on medication.

How similar studies have performed: While the use of eTNS for ADHD is relatively novel, previous studies have indicated its potential effectiveness, warranting further investigation.
