Is this trial a fit for you?

Likely a good fit

Ideal candidates are young adults aged 16-35 with autism spectrum disorder and clinically significant depression, without co-occurring intellectual disabilities.

Probably not a fit

Patients with a history of substance use disorders or significant medical or neurological illnesses may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in treating major depressive disorder in transition-aged youth with autism spectrum disorder. The study employs a randomized, double-blind, sham-controlled design, administering bilateral theta burst stimulation to the dorsolateral prefrontal cortex over 30 sessions across six weeks. Participants aged 16-35 without co-occurring intellectual disabilities and with clinically significant depression will be recruited. The trial aims to explore the treatment's efficacy while also utilizing MRI to understand the mechanisms behind treatment responses.

Why it matters

Potential benefit: If successful, this treatment could provide a new, effective option for managing depression in young adults with autism.

How similar studies have gone: Previous studies have shown promising results for rTMS in treating depression in non-autistic populations, but this specific application in autism is novel.
