Motor inhibition and cognitive flexibility in eating disorder subtypes

Clinical investigation of set-shifting subtypes in anorexia nervosa

“…Interestingly, our group demonstrated that adult AN patients are rigid not only in verbal but also in non-verbal domains, as recently confirmed (Pignatti and Bernasconi, 2013). Still, cognitive alterations have been found to play a role not only as vulnerability and maintaining factors but also as biological markers (Steinglass et al, 2006;Galimberti et al, 2012;Roberts et al, 2013).…”

Facets of impulsivity interactively predict body fat and binge eating in young women

“…Some studies found greater delay discounting or poorer response inhibition in obese adults compared to normal-weight individuals (Mobbs, Iglesias, Golay, & Van der Linden, 2011;Nederkoorn, Smulders, Havermans, Roefs, & Jansen, 2006;Weller, Cook, Avsar, & Cox, 2008) or in adults with BED or BN compared to controls (Manwaring, Green, Myerson, Strube, & Wilfley, 2011;Rosval et al, 2006;Wu et al, 2013). These findings, however, are contrasted by a number of studies that did not find differences in delay discounting or response inhibition between those groups (Claes, Mitchell, & Vandereycken, 2012;Claes, Nederkoorn, Vandereycken, Guerrieri, & Vertommen, 2006;Galimberti, Martoni, Cavallini, Erzegovesi, & Bellodi, 2012;Hendrick, Luo, Zhang, & Li, 2012;Loeber et al, 2012;Nederkoorn et al, 2006;Van den Eynde et al, 2012;Wu et al, 2013).…”

Neural signature of behavioural inhibition in women with bulimia nervosa

“…[6][7][8][9] Inhibitory control refers to the ability to suppress inappropriate and unwanted actions. 10 Impaired response inhibition in individuals with bulimic-type eating disorders is not limited to binge eating, but frequently includes several impulsive behaviours (e.g., excessive drinking, substance abuse), 11 suggesting a more general dysregulation.…”
