Transcranial Magnetic Stimulation (TMS) to Treat Depression in Autism Spectrum Disorder

Summary

This study will assess clinical and behavioral measures along with electroencephalogram (EEG), event-related potentials (ERPS), and eye-tracking (ET) prior to and following a single intermittent Theta Burst Stimulation (iTBS) session to provide preliminary insight into the potential of TMS as an intervention for depression in individuals with Autism Spectrum Disorder (ASD).
