Summary

This study planned to test vagus nerve stimulation (VNS) in children and adults with autism and developmental disabilities to see if it could improve behavior, thinking, and body rhythms. Participants would have chosen 1 to 3 months of daily VNS and completed monthly check-ins. The study was withdrawn before enrolling anyone, so no results are available.
