Other studies are investigating the neurobiology of emotional and social behavior relevant to bulimia and the neuroscience of feeding behavior.
Scientists have learned that both appetite and energy expenditure are regulated by a highly complex network of nerve cells and molecular messengers called neuropeptides. These and future discoveries can provide potential targets for the development of new pharmacologic treatments for bulimia.
Further insight is likely to come from studying the role of gonadal steroids. Their relevance to bulimia is suggested by the apparent link between gender and eating disorders, their emergence at puberty or soon thereafter, and the increased risk for eating disorders among girls with an early onset of menstruation.
