Transcutaneous Vagus Nerve Stimulation for Misophonia Relief

A 64-year-old woman with severe misophonia, whose main trigger was the sound of a bouncing basketball, experienced a dramatic and sustained reduction in her symptoms after a one-month course of a non-invasive nerve stimulation therapy. The case report, led by researchers Francesca Proietti, Massimo Marano, and Emanuele Rizzo, suggests that targeting the body’s autonomic nervous system may be a promising new approach for a condition where treatment evidence remains limited.

Targeting the Autonomic Storm in Misophonia

For this patient, the rhythmic thud of a basketball was not just an annoyance; it triggered a cascade of intense physical and emotional distress. Exposure caused palpitations, a choking sensation, difficulty breathing, acute anxiety, terror, and an overwhelming urge to flee. These symptoms point to a profound dysregulation of the autonomic nervous system—the system that controls our “fight-or-flight” response. While current treatments often focus on psychological strategies like cognitive reappraisal, this case explored a physiological intervention aimed directly at calming this autonomic hyperarousal.

The taVNS Intervention Protocol

The patient, who was already on stable medication (sertraline), underwent a one-month protocol of bilateral transcutaneous auricular vagus nerve stimulation (taVNS). This non-invasive technique involves placing small electrodes on the outer ear to deliver a mild electrical current, stimulating a branch of the vagus nerve. The stimulation was applied for 60 minutes daily at an intensity the patient found noticeable but not painful. The vagus nerve is a major component of the parasympathetic nervous system, which acts as a counterbalance to the body’s stress response. The rationale was that stimulating this nerve could help regulate the extreme autonomic reactions triggered by misophonic sounds.

Substantial and Sustained Symptom Reduction

The primary measure of success was the Duke Misophonia Questionnaire Symptoms Composite Scale. The patient’s score fell dramatically from a severe 80 at baseline to 9 after the one-month treatment. Critically, this improvement held at the one-month follow-up, with a score of 5. This indicates a robust and lasting reduction in the core distress caused by trigger sounds.

Secondary measures also showed significant gains. Overall psychological distress, along with specific symptoms of somatization, anxiety, hostility, and depression, all improved. This broad psychological benefit aligns with the role of the vagus nerve in mood regulation and suggests the treatment’s effects may extend beyond the immediate sound-triggered response.

A Complex Picture for Function and Sleep

Not all outcomes followed the same positive trajectory. The researchers observed a notable dissociation between symptom reduction and the patient’s perceived ability to function in daily life. While self-reported functional impairment decreased right after treatment, it increased again at the one-month follow-up, even though misophonia severity scores remained low. Sleep quality showed a similar pattern, improving post-treatment but returning to baseline levels at follow-up.

This disconnect highlights a critical point for therapy: reducing the intensity of a reaction is not the same as restoring confidence and engagement in life. It suggests that even effective biological interventions might need to be combined with rehabilitative or psychological support to achieve full functional recovery. The temporary sleep improvement is also interesting, given the known links between tinnitus, depression, and sleep quality in related auditory disorders.

Implications and Future Research Directions

This single case report, detailed in the journal Frontiers in Psychology (DOI: 10.3389/fpsyg.2026.1903444), is not definitive proof of efficacy. However, it provides a strong scientific rationale for conducting larger, controlled studies. It positions taVNS as a plausible adjunctive intervention, particularly for individuals with misophonia characterized by strong physical, autonomic reactions.

The findings add a new dimension to the search for otoactive compounds and targets in hearing disorders, suggesting neuromodulation of central nervous system pathways is a viable avenue. Furthermore, the study underscores the value of brain imaging advances in future work to visualize how taVNS might alter brain networks involved in misophonia.

For patients and clinicians, this case offers a note of cautious optimism. It highlights that the physiological component of misophonia is a valid treatment target. Future research must determine optimal stimulation parameters, which patients are most likely to benefit, and how to integrate such neuromodulation with behavioral strategies to ensure improvements in both symptoms and daily function.
