简要总结
This is a pilot study to examine the tolerability, safety and early efficacy of two forms of transcranial magnetic stimulation (TMS) for treating adolescents with Obsessive Compulsive Disorder (OCD) who have experienced limited improvements with usual treatments for OCD in adolescents.
The project's primary goal is to examine whether adolescents can complete 3 consecutive weeks of TMS administered 5 days per week, and to describe the type of and how common individual side effects with TMS occur in adolescents with OCD.
Participants will:
- visit the clinic every weekday for 3 weeks (15 days) to receive TMS treatments
- have a brain MRI scan before TMS treatments begins and after finishing all TMS
- complete questionnaires and report changes in behavior and physical symptoms
详细描述
This study's primary goal is to examine whether treatment with two forms of transcranial magnetic stimulation (TMS) called theta burst stimulation (TBS) show acceptable tolerability, safety, and preliminary signals of efficacy for adolescents with Obsessive Compulsive Disorder (OCD) that has not responded satisfactorily to 1st line treatments. While TMS is FDA-approved for OCD in adults, data on TMS in youth with OCD is limited. Results will inform on how suitable TMS treatment is for adolescents with OCD, and guide future, larger studies.
The study is considered a randomized, single blind, clinical trial.
The design of the study is a two-group parallel comparative study of two different TMS stimulation sites, the orbito-frontal cortex (OFC) and the dorsal medial prefrontal cortex (dmPFC).
Model description: both groups will receive active TMS treatment sessions in clinic every weekday for 3 consecutive weeks (15 days). During each TMS session, participants in both groups will receive 3 TMS stimulations separated by a rest period, for a total of 45 individual TMS treatments. Study participants will receive TMS to only their assigned stimulation site.
Number of arms: there are two treatment arms based on assigned treatment site, an OFC arm and a dmPFC arm.
