Anticipatory and Consummatory Responses Across Reward Domains in Adolescents With Anorexia Nervosa.

Measures of both anticipatory and consummatory reward were reduced among adolescents with AN with a short duration of illness. In this study, eating disorder symptoms were related to diminished reward responses in anticipation of food. Dampened anticipatory reward response may comprise a mechanism of illness in AN that should be subject to further study.
