Why is it important to understand BDD?
It's important to understand BDD because we really need to develop good treatments for it. And as of right now we understand a lot of the symptoms of BDD, we understand how to identify people with BDD, and there are few treatments that can actually work fairly well, but we really don't understand everything there is about what's going on in a person, like how much is this related to their brain chemistry, how much of it's related to their processing visual information, how much is related to societal effects, how much is related to their own psychological issues. Most likely all these things contribute, but unless we understand BDD better, the treatments may not work for everybody. Or they may not work as well as they could, so we really want to understand BDD, so we can develop better treatments for it.
