[Body dysmorphic disorder as an obsessive-compulsive spectrum disorder].

Considerable evidence supports consideration of body dysmorphic disorder (BDD) and obsessive-compulsive disorder as related disorders. BDD may share common phenomenological and neurobiological features with OGD and other disorders characterized by repetitive thoughts and behaviors and mediated by serotonin dysfunction. Within this substrate, specific psychological and sociological factors may shape the specific BDD syndrome. Further research incorporating dimensional models of these disorders, may delineate specific similarities and differences.
