NCT06698328

Brief Summary

The purpose of this study is to explore whether a non-invasive form of ear stimulation called transcutaneous auricular vagus nerve stimulation (taVNS) can manage symptoms in patients with autism spectrum disorder (ASD). Additionally, this study also uses magnetic resonance imaging (MRI) to capture images of participants' brains and apply an image processing method called INSCAPE to track brain state changes during taVNS treatment in ASD. Investigators will recruit up to 16 participants with ASD.

Outcome Measures

Primary Outcomes (1)

  • Number of participants experiencing adverse outcomes as measured by questionnaire

    Assessing adverse outcomes via qualitative questionnaire asking participants about experiences during stimulation and any consequences after stimulation.

    1 month of experimental at-home taVNS treatment

Secondary Outcomes (3)

  • Dynamic Brain States Change Relative to ASD through fMRI

    fMRI imaging will be conducted at baseline and at the 1 month follow-up final visit

  • Anxiety rating for participants using the generalized anxiety disorder -child scale

    Through study completion, up to 2 months

  • Empagthic abilities as measured by the Toronto Empathy Questionnaire

    Through study completion, up to 2 months

Study Arms (2)

Active Vagus Nerve Stimulation

ACTIVE COMPARATOR

This active vagus nerve stimulation uses electrodes on the ear to be administered twice daily, seven days per week, for four weeks at-home.

Device: Transauricular Vagus Nerve Stimulation

Sham Stimulation

SHAM COMPARATOR

This sham nerve stimulation uses electrodes on the ear to be administered twice daily, seven days per week, for four weeks at-home.

Device: Sham Stimulation

Interventions

Mild non-invasive electrical stimulation to the vagus nerve using electrodes or "stickers" that adhere to the ear and the surrounding area.

Active Vagus Nerve Stimulation

Sham non-invasive electrical stimulation using electrodes or "stickers" that adhere to the ear and the surrounding area.
