Background: Attention Deficit Hyperactivity Disorder (ADHD) affects 5-10% of children and 2-5% of adults globally, characterized by inattention, hyperactivity, and impulsivity. Traditional treatments like pharmacotherapy and behavioral interventions, while effective, are often limited by side effects and accessibility issues.Objective: This study assesses the effectiveness and safety of Deep Brain Sound Stimulation (DBSS), a novel non-invasive auditory therapy, based on user-reported outcomes from individuals with ADHD.Methods: We analyzed feedback from 439 users who completed DBSS therapy via the Vital Tones mobile application on the Apple App Store. Additionally, 20 participants provided detailed responses through in-app surveys evaluating symptom improvements in attention, hyperactivity, and cognitive performance. Descriptive statistics were used to determine median effectiveness and satisfaction rates.Results: The therapy demonstrated a high user satisfaction rate of 99.32%, with a minimal refund rate of 0.68%. Survey respondents reported a median symptom improvement of 57% (95% CI: 40.33%–73.00%). DBSS was well-tolerated, with only minor side effects reported in a small number of sessions.Conclusion: Preliminary findings indicate that DBSS is a promising non-invasive treatment for ADHD, offering significant symptom improvement and high user satisfaction. However, the observational nature of the study, small survey sample, and reliance on self-reported data suggest that further controlled research is necessary to validate these results and establish DBSS's efficacy and safety.
