Cognition and Behavior With Sham Accelerated TMS (NCT07397858)
🩺 Plain-English Summary (8th-Grade Level)
The goal of this clinical study is to understand how a person's expectations about treatment can influence their mood, motivation, and reactions to everyday rewards. The study includes young people ages 15-25 who will complete a sham (placebo) version of an accelerated transcranial magnetic stimulation (TMS) treatment. No active brain stimulation is given. The main questions this study aims to answer are: 1. Do expectancy and treatment beliefs change during and after an accelerated sham TMS schedule? 2. Do these expectations influence mood, reward processing, or craving? 3. Does a more intensive schedule of sham sessions lead to different expectancy effects than a slower, once-daily schedule? Participants will: * Complete baseline clinical assessments and an MRI session * Undergo five days of accelerated sham TMS (no active brain stimulation is delivered) * Complete post-treatment MRI and follow-up assessments at 1 week and 4 weeks
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (4 items) and avoid the listed exclusions (6 items).

📋 "Do I Qualify?" — 1-Minute Self Screener
Instant ChecklistCheck every box below. If you can check all of them, you may meet the study's basic screening requirements (final eligibility is confirmed by the site team).
Usually NOT eligible if any of the following apply:
- Exclusion Criteria:
- Past exposure to Transcranial Magnetic Stimulation
- Unable to consent (due to medical condition, psychosis, substance use, etc)
- Acute suicidal crisis or with active medical illness that would interfere with participation
- Contraindications to receiving MRI as determined by screening questionnaires (Contraindications for MRI include metal in the body related to an injury or surgery, for example, surgical clips, metal fragments in the eyes, or piercings that cannot be removed. Subjects with braces or permanent retainers will not be scanned, because the effects on image signal are not well understood and may affect comparability between subjects and scan sites. Participants will be excluded for major neurological problems, such as seizure disorder, traumatic brain injury with loss of consciousness, or sensory problems that may impair task performance, such as blindness.)
- Participation in any clinical study with exposure to any investigational treatment or product within the previous 30 days, or plan on concurrent participation in other studies
