Body image disturbance
Résumé
Body image disturbance (BID) is a common symptom in patients with eating disorders and is characterized by an altered .
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. 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).
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, and is regarded as difficult to treat. Thus, effective body image interventions could improve the prognosis of patients with ED, as experts have suggested. However, there is no hard evidence that current treatments for body image disturbance effectively reduce eating disorder symptoms. Furthermore, pharmacotherapy is ineffective in reducing body misperception and it has been used to focus on correlated psychopathology (e.g., mood or anxiety disorders). However, to date, research and clinicians are developing new therapies such as virtual reality experiences, mirror exposure, or multisensory integration body techniques, which have shown some extent of efficacy.
The scientific study of bodily experiences began at the end of the 19th century. German physiologist Hermann Munk was the first to suggest the existence of a cortical representation of the body, supported by his vivisection experiments on the parietal cortex of dogs. A few years later, Carl Wernicke hypothesized a cortical map capable of collecting and processing sensory inputs from every point of the body. In 1905 Bonnier introduced the term body schema, defining it as the mental representation of the body necessary for the brain to perceive objects near, far, or within the body itself.
