A research team from UCLA under the leadership of doctor Faustner performed brain scans of 14 adults diagnosed with BDD and 16 healthy controls in order to map the brain's connections to examine how the white-matter networks are organised.

People with BDD had a pattern of abnormally high network "clustering" across the entire brain. This suggests that these individuals may have imbalances in how they process "local" or detailed information. The researchers also discovered specific abnormal connections between areas involved in processing visual input and those involved in recognizing emotions.
