Eating Disorder Behaviors Appear To Change Brain Reward Processing, Scan Study Indicates

Healio (7/1, Gramigna) reports, “Eating disorder behaviors appeared to change brain reward processing,” researchers concluded in a functional brain imaging study that sought “to evaluate brain response during unexpected receipt or omission of a salient sweet stimulus in 317 women, of whom 197 had eating disorders and 120 served as healthy controls, and to determine whether this brain response was linked to the ventral striatal-hypothalamic circuitry, which has correlated with food intake control.” The study revealed that “BMI modulated prediction error and food intake control circuitry in the brain, and alteration of this circuitry may reinforce eating disorder behaviors when paired with behavioral traits linked to overeating or undereating, researchers noted.” The findings were published online June 30 in JAMA Psychiatry. HealthDay (7/1, Preidt) also covers the study.
