The effects of prefrontal cortex transcranial direct current stimulation (tDCS) on food Craving and temporal discounting in women with frequent food Cravings.
Appetite, 2014Co-Authors: Maria Kekic, Iain C Campbell, Jessica Mcclelland, Steffen Nestler, Katya Rubia, Anthony S. David, Ulrike SchmidtAbstract:Abstract Bulimia nervosa, binge-eating disorder, and some forms of obesity are characterised by compulsive overeating that is often precipitated by food Craving. Transcranial direct current stimulation (tDCS) has been used to suppress food Cravings, but there is insufficient evidence to support its application in clinical practice. Furthermore, the potential moderating role of impulsivity has not been considered. This study used a randomised within-subjects crossover design to examine whether a 20-minute session of sham-controlled bilateral tDCS to the dorsolateral prefrontal cortex (anode right/cathode left) would transiently modify food Cravings and temporal discounting (TD; a measure of choice impulsivity) in 17 healthy women with frequent food Cravings. Whether the effects of tDCS on food Craving were moderated by individual differences in TD behaviour was also explored. Participants were exposed to food and a film of people eating, and food Cravings and TD were assessed before and after active and sham stimulation. Craving for sweet but not savoury foods was reduced following real tDCS. Participants that exhibited more reflective choice behaviour were more susceptible to the anti-Craving effects of tDCS than those that displayed more impulsive choice behaviour. No differences were seen in TD or food consumption after real versus sham tDCS. These findings support the efficacy of tDCS in temporarily lowering food Cravings and identify the moderating role of TD behaviour.

repetitive transcranial magnetic stimulation reduces cue induced food Craving in bulimic disorders
Biological Psychiatry, 2010Co-Authors: Frederique Van Den Eynde, Rudolf Uher, Andrew Mogg, Angelica M Claudino, Linda Horrell, Daniel Stahl, Wagner Silva Ribeiro, Iain C CampbellAbstract:Background Craving or the "urge to consume" is a characteristic of bulimic eating disorders and addictions. Dysfunction of the dorsolateral prefrontal cortex (DLPFC) is associated with Craving. We investigated whether stimulation of the DLPFC reduces food Craving in people with a bulimic-type eating disorder. Methods Thirty-eight people with bulimic-type eating disorders were randomly allocated to receive one session of real or sham high-frequency repetitive transcranial magnetic stimulation (rTMS) to the left DLPFC in a double-blind procedure. Outcome measures included self-reported food Craving immediately after the stimulation session and frequency of bingeing over a 24-hour follow-up period. Results Compared with sham control, real rTMS was associated with decreased self-reported urge to eat and fewer binge-eating episodes over the 24 hours following stimulation. Conclusions High-frequency rTMS of the left DLPFC lowers cue-induced food Cravings in people with a bulimic eating disorder and may reduce binge eating. These results provide a rationale for exploring rTMS as a treatment for bulimic eating disorders.

effect of left prefrontal repetitive transcranial magnetic stimulation on food Craving
Biological Psychiatry, 2005Co-Authors: Rudolf Uher, Daniella Yoganathan, Andrew Mogg, Savithasri V Eranti, Janet Treasure, Iain C Campbell, Declan M Mcloughlin, Ulrike SchmidtAbstract:Background: Dysfunction of the prefrontal cortex is implicated in Craving for drugs and food. This study explores the effect of prefrontal cortex stimulation on food Craving. Methods: In a randomized double-blind parallel group study, 28 women, who reported frequent Cravings for food were exposed to foods that typically elicit strong Cravings before and after a single session of real or sham 10-Hz repetitive transcranial magnetic stimulation to the left dorsolateral prefrontal cortex at an intensity of 110% individual motor threshold. Results: Self-reported food Craving during exposure to the experimental foods remained stable before and after real stimulation compared with sham stimulation in which Cravings increased over the experimental session. Consumption of snack foods within a 5-min period after stimulation did not differ between groups. Conclusions: Prefrontal stimulation inhibits the development of Craving. A longer period of observation is necessary to establish whether there is an effect on food consumption.
