The goal of this proposal is to investigate whether a standard rTMS protocol for depression, including multiple sessions applied to left dorsolateral prefrontal cortex (DLPFC) results in reduction of depressive symptoms for adult patients with ASD and MDD (Aim 1). The secondary goal is to investigate and whether there is any beneficial reduction in the core symptoms of autism (Aim 2).
Aim 1. Determine the safety and therapeutic efficacy of left-sided DLPFC high frequency rTMS on MDD symptoms in patients with ASD: The investigators hypothesize that patients receiving the rTMS will tolerate the treatment course without difficulty and have clinically significant reduction of depressive symptoms after receiving all 25 sessions, as compared with their symptom burden prior to initiating TMS. Depression symptom data will be collected as pre- and post-TMS scores on Hamilton Depression Rating Scale (HAM-D). Depression scores will also be monitored periodically during course of TMS with Patient Health Questionnaires (PHQ-9). Exploratory sub-aim - Monitoring for durability of response: The investigators hypothesize that subjects receiving rTMS will demonstrate durability of response in their depression symptom reduction, as measured by HAM-D scores at 1 month and 3 months post-TMS. Aim 2. Determine the effect of left DLPFC rTMS on core symptoms of ASD: The investigators hypothesize that subjects will experience reduction in core symptoms of ASD after completing all 25 sessions, as compared with their symptom burden prior to initiating treatment. For social and communication deficits, informant and/or self-report evaluations will be made pre- and post-TMS with the Social Responsiveness Scale (SRS), the Ritvo Autism Aspergers Diagnostic Scale-Revised (RAADS-R) and the Aberrant Behavior Checklist (ABC). Repetitive and restricted behavior will be evaluated using the Repetitive Behavior Scale-Revised (RBS-R), the ABC, and RAADS. Exploratory sub-aim: Determine if there are changes to functional brain connectivity during face and object processing tasks via functional MRI imaging in patients with Autism who receive rTMS: The study investigators hypothesize that there will be altered brain connectivity evident in patients' baseline fMRI during cognitive processing tasks prior to TMS reflected as both hyper- and hypo-connectivity, and that there will be some level of normalization of these patterns in fMRI after completion of TMS series, particularly in the prefrontal cortex. Exploratory sub-aim - Monitoring for durability of response: The study investigators hypothesize that subjects receiving rTMS will exhibit durability of response in their ASD symptom reduction, as measured by ABC, SRS, RAADS, AND RBR scores at 1 month and 3 months post-TMS.

Change From Baseline in Aberrant Behavior Checklist
Aberrant Behavior Checklist. Minimum 0, maximum 174. Higher scores indicate worse behaviors.
Time frame: Baseline, Week 5, Week 9, Week 17
Change From Baseline in Social Responsiveness Scale-2
Social Responsiveness Scale-2. Minimum 0, maximum 195. Higher indicates worse behaviors
Time frame: Baseline, Week 5, Week 9, Week 17
Change From Baseline in Ritvo Autism-Aspergers Diagnostic Scale
Ritvo Autism-Aspergers Diagnostic Scale. Minimum 0, maximum 240. Higher indicates worse symptoms.
Time frame: Baseline, Week 5, Week 9, Week 17
Change From Baseline in Repetitive Behavior Scale-Revised
Repetitive Behavior Scale-Revised Global Impression. Minimum 0, maximum 100. Higher indicates worse behaviors
