ABSTRACT
Avoidant/restrictive food intake disorder (ARFID) is diagnosed when food avoidance leads to clinically significant nutritional, weight/growth, or psychosocial impairment. As many as 81.5% of children and adolescents diagnosed with ARFID have a history of a medical condition associated with pain, fatigue, or malaise. ARFID is diagnosed and treatment begins after the medical condition is resolved but food avoidance remains. Effective treatment involves repeated exposure to eating food and related stimuli aimed at creating inhibitory learning to counteract learned fears and aversions. Treatment usually involves positive reinforcement of food approach behavior and escape extinction/response prevention to eliminate food avoidant behavior. To shed light on the neural mechanisms that may maintain ARFID and to identify candidate pharmacological treatments for adjuncts to behavioral interventions, this paper systematically reviews research on drug treatments that successfully reduce conditioned taste aversions (CTA) in animal models by disrupting reconsolidation or promoting extinction. The mechanism of action of these treatments, brain areas involved, and whether these CTA findings have been used to understand human eating behavior are assessed. Collectively, the results provide insight into possible neural mechanisms associated with resuming oral intake following CTA akin to the therapeutic goals of ARFID treatment and suggest that CTA animal models hold promise to facilitate the development of interventions to prevent feeding problems. The findings also reveal the need to investigate CTA reduction in juvenile and female animals and show that CTA is rarely studied to understand disordered human feeding even though CTA has been observed in humans and parallels many of the characteristics of rodent CTA.
