Patients suffering from Body Dysmorphic Disorder perceive themselves as ugly and deformed. A new imaging study by UCLA psychiatrist Dr. Jamie Feusner, shows that the brains of people with BDD abnormally process visual details, which causes them to see differently. Larry talks with Dr. Feusner and patient Aron Cowen about the study's findings which are the first to demonstrate a biological reason for patients' distorted self-image.
