This video covers body dismorphic disorder (BDD) as well as two lesser known subtypes. First is muscle dismorphia (when an individual perceives themself as being less muscular than they are) and the second is body dismorphic disorder by proxy, where the symptoms of BDD are targeted at another individual.
