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 COMPARATORThis active vagus nerve stimulation uses electrodes on the ear to be administered twice daily, seven days per week, for four weeks at-home.
Sham Stimulation
SHAM COMPARATORThis sham nerve stimulation uses electrodes on the ear to be administered twice daily, seven days per week, for four weeks at-home.
Interventions
Mild non-invasive electrical stimulation to the vagus nerve using electrodes or "stickers" that adhere to the ear and the surrounding area.
Sham non-invasive electrical stimulation using electrodes or "stickers" that adhere to the ear and the surrounding area.
