Accelerated Intermittent Theta Burst Stimulation for Adolescent and Young Adult Depression With Elevated Suicide Risk

The goal of this clinical trial is to learn if a fast-acting brain stimulation treatment called transcranial magnetic stimulation (TMS) can help people with depression and suicidal thoughts. The treatment is non-invasive (does not involve surgery or medications), is given over 5 days, and uses brain imaging (MRI) to guide which part of the brain to target. This study tests whether this treatment is a helpful and practical option for adolescents and young adults who are depressed and have suicidal thoughts. We want to see if: 1. This treatment is feasible and acceptable to patients 2. It can reduce depression and suicidal thoughts 3. It can lower the chance of going to the hospital 4. It affects daily functioning (school, work, relationships) All participants will undergo 5-days of TMS treatment and complete MRI brain scans before and after treatment. They will return for check-ups after 1 week and 4 weeks.
