Summary

This trial tests the effects of transcranial magnetic stimulation (TMS) on visual processing in adults with body dysmorphic disorder (BDD). TMS uses magnetic fields to stimulate specific brain areas, aiming to improve how these individuals perceive their appearance. The study hopes to find new ways to help people with BDD by enhancing their brain's visual processing capabilities. TMS is a noninvasive technique that has been used for diagnostic and therapeutic purposes in various neuropsychiatric disorders, including depression and bipolar disorder.

Who is the study for?
This trial is for adults aged 18-40 with primary concerns about their face or head appearance, who meet the criteria for Body Dysmorphic Disorder (BDD) according to DSM-5. They should score ≥8 on the Dysmorphic Concern Questionnaire and have a BDD-YBOCS score of ≥20. Participants must not be on medications related to BDD or any other condition for at least 8 weeks before joining.
What is being tested?
The study tests two types of TMS: intermittent and continuous theta burst stimulation, focusing on how they affect visual processing in those with BDD symptoms. Each participant will undergo one type of TMS followed by an fMRI scan while viewing images of their faces, then switch the type of TMS the next day.
What are the potential side effects?
TMS may cause discomfort at the stimulation site, headache, lightheadedness, or seizures in very rare cases. The fMRI procedure is non-invasive but can be uncomfortable due to loud noises and confined space.
