Body image distortions in bulimia nervosa: Investigating body size overestimation and body size satisfaction by fMRI

Altered intrinsic functional brain architecture in female patients with bulimia nervosa

“…45 The relevance of the sensorimotor and occipital regions to distorted body image has been emphasized in several previous studies. [9][10][11]14 For instance, reduced occipitotemporal responses during presentations of underweight or overweight human bodies were observed in patients with bulimia nervosa; 9 the lateral occipital activation was sensitive to stimuli of body size distortions in healthy people, whereas such a modulation was not observed in those with bulimia nervosa. 10 At rest, patients with bulimia nervosa showed abnormal iFC within the somatosensory network and between the paracentral lobule and 2 occipital regions.…”

“…We hypothesized that patients with bulimia nervosa would show abnormal topological properties in functional brain networks and that the functional disturbances would be apparent in the cortical and subcortical regions involved in reward and emotional processing, sensorimotor and visual perception, and interoception, based on potential relevance of these neural functions to bulimia nervosa. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] We also examined the behavioural/symptom correlates of these network properties.…”

Wide impairment of cerebral serotoninergic activity but inter-individual heterogeneity in bulimia nervosa patients: a pilot [18F]MPPF/PET study

“…Prefrontal cortex areas including part of inferior, middle and superior frontal gyrus also presented with lateral asymmetric activation in insula cortex in BN subjects (Andreason et al 1992;Nozoe et al 1995) that appeared to be independent of the mood state (Andreason et al 1992) but related to own body image or food images perception (Brooks et al 2011;Mohr et al 2011). The left insula was reported as the only cortex region to present a decreased μ -opioid receptor binding in bulimic subjects (Bencherif et al 2005).…”
