Adult avoidant/restrictive food intake disorder: a case report

Transtorno alimentar evitativo/restritivo em uma adulta: um relato de caso

ABSTRACT

The aim this report is to present an adult case of avoidant/restrictive food intake disorder (ARFID) in a patient with atypical development. To emphasize the diagnostic and behavioral characteristics of this new nosological category included in the Feeding and Eating Disorders (FED) section of DSM-5. A woman with Down Syndrome in early adulthood who developed restriction and avoidance symptoms of food until the total eating refusal with weight loss, malnutrition and dependence exclusively on enteral feeding by gastrostomy tube. This case exemplified how ARFID may remain a hidden diagnosis and even be misdiagnosed as other eating disorders, such as anorexia nervosa. The increase in diagnostic suspicion for this nosological entity with neurobiological/behavioral mechanisms involved in its clinical presentations in mind, might increase knowledge about this serious eating disorder, aiming the development of evidence-based interventions.
