About this trial
The goal of this clinical trial is to learn if external trigeminal nerve stimulation (eTNS) works to treat ADHD symptoms in children on the autism spectrum (ASD). It will also learn about the efficacy and tolerability of the eTNS device. The main questions it aims to answer are:
* Does eTNS reduce ADHD symptoms? * Does eTNS improve core and associated features of ASD?
Participation spans 8-12 weeks and includes:
* 4-5 in-person visits * 4 brief virtual check-ins * Nightly use of the eTNS device with a small sticky patch applied to child's forehead * Randomized assignment (those who start with the sham device may try the active device later)

Treatment groups
Trial outcomes
Primary outcomes
Change in ADHD Symptoms
Examine the efficacy of external Trigeminal Nerve Stimulation (eTNS) in reducing ADHD symptoms as measured by the Attention-Deficit/Hyperactivity Disorder Rating Scale-5 (ADHD-RS-5; range 0-54), where higher scores indicate worse symptoms.
Secondary outcomes
Change in Social Responsiveness
Examine changes in social communication and related behaviors as measured by the Social Responsiveness Scale, Second Edition, Short Form (SRS-2-SF; range 0-48), where higher scores indicate worse impairment.
Change in Restricted and Repetitive Behaviors
Examine changes in restricted and repetitive behaviors as measured by the Repetitive Behavior Scale-Revised (RBS-R; range 0-129), where higher scores indicate more severe repetitive behaviors.
Change in Sleep Quality
Examine changes in sleep quality as measured by the Children's Sleep Habits Questionnaire (CSHQ; range 33-99), where higher scores indicate poorer sleep quality.
