Body dissatisfaction (BD) is a condition derived from negative thoughts and feelings about one's body and is a core symptom of the eating disorder anorexia nervosa (AN). Beingdissatisfied with one’s body is highly present in women and to some extent men. This might be a result of a skewed ideal in combination with social influences. In recent year, research on neurobiological risk factors as well as neuroscientific and cognitive mappings of AN and BD have gained traction, particularly when it comes to studies using neuroimaging- techniques and cognitive tests. Studies have identified brain regions (insular cortex, anterior cingulate cortex, parietal cortex, amygdala, dorsolateral and orbitofrontal areas of the prefrontal cortex) associated with the processing of body shape as well as dysfunctional processing of self-image and body satisfaction. Structural imaging studies of AN patients using CT and MRI have, in many cases, found reduced cerebral volume, increased spinal fluid (CSF) and enlarged ventricles. Usually, food and water restriction has been seen as the cause, and structural deficits in AN patients have shown to improve with weight gain after long-term recovery.
