LIVE SESSION - SYMPOSIUM: IS ANOREXIA NERVOSA AN EATING DISORDER?
Chair/Organizer: Walt Kaye
Virtual Meeting

Although anorexia nervosa (AN) is called an eating disorder, many believe restricted eating and emaciation in AN occurs secondarily to body image disturbances, or other cognitive factors. This symposium will discuss new evidence suggesting that disturbances within the neural circuitry regulating eating, reward, and motivation contribute to AN. Edmund Rolls will review his seminal work on the neurocircuitry of food reward, followed by 3 talks presenting new data on this circuitry in AN. This question is a critical limitation and challenge because the primary focus and cost of higher levels of care for AN is nutritional restoration and weight gain. However, limited progress has been made as the rate of relapse remains high and no treatments normalize eating behavior. New insights into mechanisms of pathological eating in AN are needed to advance the search for more effective treatments.
