Eating Disorder Research Program
EDCare participates actively in important leading medical research on eating disorders, with our Executive Clinical Director, Dr. Tamara Pryor, also serving as Director of Clinical Research. We collaborate closely with Dr. Guido Frank, Associate Director of the Eating Disorders Program and Director of the Developmental Brain Research Program at Children’s Hospital Colorado. Dr. Frank researches the biology and behavior of adolescents and adults with eating disorders. In just the past few years since he began collaborating with EDCare, he has published over 30 articles on the topic in peer-reviewed journals – many of them co-authored by Dr. Pryor, and including patients participating from EDCare.
“It is OK to doubt what you have been taught to believe.”
Developmental Brain Research Focused on Eating Disorders
Anorexia (AN) and Bulimia Nervosa (BN) are severe psychiatric disorders that most commonly begin during adolescence – which is a critical period of significant change in both biological and psychosocial development. Neurobiological and genetic factors have only recently been recognized as contributing to the development of AN and BN, in addition to well-known psychological and environmental factors. This new understanding of the etiology of eating disorders (ED) lays the foundation for a developmental neuroscience perspective in ED research.
“Brain imaging provides a window into the living human brain and may help us understand mechanisms that cause eating disorders. Only if we know how the brain works differently in eating disorders then we can work to improve treatment and make recovery more successful.” Guido Frank, MD., FAED
Current Eating Disorder Research at EDCare
Dr. Frank is conducting a study, funded by the National Institutes of Health, in females ages 16 to 29 years. They are admitted into EDCare’s Partial Hospitalization Program as well as the Eating Disorders Program at Children’s Hospital Colorado. This study allows for any diagnosis of an eating disorder as well as co-morbid anxiety or depression and most medication use. Over five years, the study will recruit 300 females with eating disorders and 100 healthy comparison control individuals.
Interested eligible patients will meet with Dr. Frank and his research team to review consent forms and study procedures. These include a diagnostic assessment, a questionnaire about mood, eating behaviors, and personality traits, and a special magnetic resonance imaging (MRI) scan. In addition to brain structure, the MRI will record reactions to patients tasting sweet and neutral stimuli during imaging.
