INTRODUCTION: Currently, there is limited understanding of the etiology of BN. While multifaceted etiology is likely, several neurobiological factors may play a role. Brain derived neurotrophic factor (BDNF), a potential biomarker linked to eating and weight disorders, is one factor of recent investigation. This paper examined studies comparing BDNF blood levels in BN to healthy control (HC) subjects.
METHODS: A systematic review of the literature was conducted utilizing five databases (PubMed, CINAHL, EMBASE, PsycINFO, and Medline). Key terms included eating disorders, BDNF, and bulimia nervosa.
CONCLUSIONS: BDNF blood levels appear lower in BN than in HC subjects; however, studies are needed to examine the influence of possible correlates including symptom severity, mood, medications, exercise, and substance use.
