CARE STUDY

Study Aim

Avoidant/Restrictive Food Intake Disorder (ARFID) is characterized by restrictive food intake for reasons that are not associated with weight and shape concerns. Individuals with ARFID may exhibit avoidance of foods due to a prior choking incident, sensory sensitivities, and/or chronic low appetite and little interest in eating.

Our study aims to investigate how ARFID can affect different hormones and regions of the brain. In this study, we use magnetic resonance imaging (MRI), psychological assessments, and evaluation of hormones in the blood to better understand brain and hormone activity, as well as behavioral markers, of ARFID.

This is a longitudinal study, which means we will monitor participants with ARFID over the course of two years. We hope to identify mechanisms that might influence what might contribute to the development and recovery of ARFID, and how this might differ among individuals in the study.

Healthy volunteers (males and females, 10-22 years old) can also participate in this study, and they will be monitored for two study visits only (not more than 3 months apart).

This study will improve the existing knowledge of ARFID, as it is a newly defined disorder in the Diagnostic and Statistical Manual (DSM-5). We hope that our findings may improve treatment options for those with ARFID.
