Background: Obsessive-Compulsive Disorder (OCD) is a chronic psychiatric condition marked by intrusive thoughts and compulsive behaviors, significantly impacting daily life. Conventional treatments, including Cognitive Behavioral Therapy (CBT) with Exposure and Response Prevention (ERP) and pharmacotherapy, are effective but limited by side effects, accessibility issues, and adherence challenges. Objective: This study investigates the efficacy and user satisfaction of Deep Brain Sound Stimulation (DBSS), a novel non-invasive treatment for OCD, designed to target brain regions involved in cognitive control and emotional regulation. Methods: DBSS uses auditory-driven brainwave entrainment to stimulate key regions associated with OCD symptoms, such as the dorsolateral prefrontal cortex (DLPFC), anterior cingulate cortex (ACC), and ventral tegmental area (VTA). This approach aims to improve connectivity in OCD-related neural circuits without overstimulation. User feedback was collected through the Vital Tones OCD app, with data from 219 users completing the full DBSS treatment and 19 users participating in a survey assessing perceived effectiveness and satisfaction. Results: High user satisfaction was reported, with 99.09% of users retaining DBSS treatment and an average reported effectiveness of 44% in symptom improvement (Confidence Interval: 22%–66%). Users noted enhanced cognitive control, reduced compulsive behaviors, and improved emotional regulation. Conclusions: DBSS shows promise as a non-invasive, accessible OCD treatment, stimulating critical brain regions involved in managing intrusive thoughts and compulsions. Although further validation through randomized trials is needed, preliminary feedback suggests DBSS may serve as an effective alternative or complement to traditional OCD therapies, addressing core neurobiological factors.
