National Eating Disorders Week: The Paradox of Perfectionism

National Eating Disorders Week Presentation NANCY ZUCKER, PhD: Our laboratory studies individuals who have difficulty detecting, interpreting, and/or using signals from their body and using this information to guide adaptive behavior. We explore how disruptions in these capacities contribute to psychosomatic disorders such as functional abdominal pain or anorexia nervosa and how the adaptive development of these capacities helps individuals to know themselves, trust themselves, and flourish. Our primary populations of study are individuals struggling with eating disorders and feeding disorders of childhood: conditions that are sine quo non for dysregulation of basic motivational drives or conditions in which disruption in these processes may be more likely: such as the presence of pediatric pain. Several conditions are of particular focus due to the presence of profound deficits in interoception or/and integration of internal arousal: anorexia nervosa, a disorder notable for extreme, determined, rigid, and repetitive behaviors promoting malnourishment and the inability to use signals of interoception and proprioception in the service of goal-directed actions, Avoidant Restrictive Food Intake Disorder (ARFID), children with "sensory superpowers" who may be hypersensitive to somatic signals and external sensory features; and pediatric functional abdominal pain, children who may become afraid of their bodies' messages due to generalization of fear of pain to innocuous sensations. Study of children allows us to ask different questions about disorder etiology, maintenance, and course as we can minimize the impact of malnutrition on brain function and perhaps better characterize prior learning history.

She completed her psychiatry residency training at Langley Porter Psychiatric Institute at UC-San Francisco and did neurosciences research as a postdoctoral fellow at UC-SF, the San Francisco VA Medical Center, and Stanford before joining the Duke faculty in 2007. Her work has been funded by NIDA, NIMH, NSF and Alfred P. Sloan and Klingenstein Fellowships in the Neurosciences, and the Brain.
