Title: Body Image in Anorexia Nervosa and Body Dysmorphic Disorder: Clinical and Neurobiological Features
Description: Anorexia nervosa (AN) and body dysmorphic disorder (BDD) share clinical features related to body image distortion, including distorted perception of appearance and overemphasis on appearance in one’s self-evaluation. In addition, they share obsessive and compulsive tendencies, poor insight, and are frequently comorbid with each other. Despite this, few studies have directly compared the phenomenology or neuropsychological functioning in AN and BDD and even fewer have compared their neurobiology. In this talk I will describe the overlapping and distinct clinical features of these disorders, as well as the neurobiological substrates of visual and emotional processing from our recent lines of research. In our research, we have used functional neuroimaging (electroencephalography – EEG – and functional magnetic resonance imaging – fMRI) to probe the neural basis of visual processing and to uncover the dynamics of brain connectivity related to fear processing. We additionally have used structural neuroimaging to understand white matter network connectivity patterns. I will also discuss our ongoing study in AN of how brain systems involved in anxiety interact with those involve in reward and how this relates to clinical trajectory. Finally, I will discuss ongoing and future studies to develop visual modulation strategies to address dysfunctional neural systems involved in visual processing, as potential tools to remediate perceptual distortions in disorders of body image.
Bio: Jamie Feusner, M.D. is professor of psychiatry and biobehavioral sciences at UCLA. He obtained his medical degree and completed his psychiatry residency training at UCLA. He then completed a psychopharmacology fellowship followed by a research fellowship in neuroimaging, and joined the UCLA faculty in 2006. Dr. Feusner’s research program seeks to understand phenotypes of perceptual and emotional processing across conditions involving body image and obsessions/compulsions, including body dysmorphic disorder (BDD), eating disorders, OCD, and gender dysphoria. Dr. Feusner published the first functional neuroimaging studies in BDD, and the first studies to directly compare the neurobiology of BDD to anorexia nervosa. He is currently funded by the NIH to study anorexia nervosa, BDD, and gender dysphoria. His clinical work includes Directorship of the UCLA OCD Intensive Treatment program. He teaches cognitive-behavioral therapy and pharmacotherapy, and is a research supervisor for postdoctoral fellows and students.
