TMS Visual Modulation in Body Dysmorphic Disorder

NCT05607121 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

No results posted yet for this study

Summary

The goal of this observational study is to test the effects of a type of noninvasive brain stimulation called transcranial magnetic stimulation (TMS) on visual processing in adults with body dysmorphic disorder symptoms when combined with modifying visual attention.

The main goals are to understand, in people with body dysmorphic disorder and people with subclinical body dysmorphic disorder:

* The effects of intermittent and continuous TMS stimulation of parietal brain regions when done right before visual attention modulation on brain functional connections.
* The effects of intermittent and continuous TMS stimulation of parietal brain regions when done right before visual attention modulation on global/holistic visual perception.

Participants will receive one type of TMS (intermittent or continuous) followed immediately by an fMRI brain scan during which they will view images of their faces. On the second day, they will do the same, but receive either the intermittent or continuous TMS stimulation that they did not receive on the first day.
