Deep Brain Sound Stimulation for Dyslexia: Precision Auditory Stimulation

Background: Dyslexia is a prevalent neurodevelopmental condition affecting approximately 5–10% of the global population. It is primarily characterized by difficulties in reading, spelling, and phonological processing, which interfere with literacy acquisition and impact educational attainment and self-esteem. Traditional treatments, including structured literacy programs, cognitive and emotional support interventions (e.g., CBT, MBIs), non-invasive brain stimulation techniques (e.g., TMS, tDCS), and complementary approaches such as omega-3 supplementation and physical exercise, are effective but often limited by issues of accessibility, cost, adherence, and the need for specialized personnel.

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 dyslexia.

Methods: We analyzed feedback from 164 users who completed the DBSS dyslexia program via the Vital Tones mobile application on the Apple App Store. Additionally, 10 participants provided detailed responses through in-app surveys evaluating symptom improvements in phonological awareness, reading fluency, and language processing. Descriptive statistics were employed to determine median effectiveness and satisfaction rates.

Results: The therapy achieved a 100% user satisfaction rate, as evidenced by zero refund requests among 164 users. Survey respondents reported a median symptom improvement of 65% (95% CI: 57%–73%). DBSS was well-tolerated, with no severe side effects reported and only minor adverse effects, such as transient dizziness and mild headaches, occurring in a small number of sessions.

Conclusion: Preliminary findings indicate that DBSS is a promising non-invasive treatment for dyslexia, 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.
