An update on body dysmorphic disorder

Abstract

The present review provides an update on current research into body dysmorphic disorder. Recent findings can be considered under four groupings: the classification of body dysmorphic disorder, its current inclusion under the somatoform disorders, and its relationship to obsessive compulsive disorder and other obsessive compulsive spectrum disorders; the psychotic 'variant' of body dysmorphic disorder, and whether it is simply a more severe form of the nonpsychotic type; the cognitive aspects of body dysmorphic disorder; and the treatment of body dysmorphic disorder, both in terms of pharmacological and psychological parameters. Body dysmorphic disorder does not sit comfortably in the somatoform disorder category, and there is a good case for it being considered part of the obsessive compulsive spectrum, although it is not merely a subtype of obsessive compulsive disorder. Insight into the illness suggests that it represents a spectrum of disorders, and a categorical delineation of 'psychotic' and 'nonpsychotic' variants cannot be supported. We are beginning to understand more about the neurocognitive aspects of body dysmorphic disorder, but more research is required to assess which deficits/aberrations (if any) are exclusive to body dysmorphic disorder as an entity, and which are a reflection of broader phenomenological manifestations. Finally, the mainstay of treatment for body dysmorphic disorder remains behaviour/cognitive behaviour therapy and serotonin reuptake inhibitors; much more work is required to identify effective interventions for those patients who fail to respond to these treatment modalities.
