The onset is mainly attributed to patients with anorexia nervosa who persistently tend to subjectively discern themselves as average or overweight despite adequate, clinical grounds for a classification of being considerably or severely underweight.[1] The symptom is an altered perception of one's body and a severe state of bodily dissatisfaction characterizing the body image disturbance. It is included among the diagnostic criteria for anorexia nervosa in DSM-5 (criterion C).[2]
The disturbance is associated with significant bodily dissatisfaction and is a source of severe distress, often persisting even after seeking treatment for an eating disorder,[3][4] and is regarded as difficult to treat.[3][5] Thus, effective body image interventions could improve the prognosis of patients with ED, as experts have suggested.[6] However, there is no hard evidence that current treatments for body image disturbance effectively reduce eating disorder symptoms.[7][8] Furthermore, pharmacotherapy is ineffective in reducing body misperception and it has been used to focus on correlated psychopathology (e.g., mood or anxiety disorders).[9] However, to date, research and clinicians are developing new therapies such as virtual reality experiences,[10][11]mirror exposure,[12] or multisensory integration body techniques,[13][14][5] which have shown some extent of efficacy.
