  "abstract": "Objective: Avoidant restrictive food intake disorder (ARFID) is a recently recognised eating disorder and is largely under-researched. Given the paucity of research examining the neurobiological and cognitive correlates of ARFID, the present systematic review aimed to synthesise and summarise existing ARFID data to highlight directions for future research.\n\nMethod: Using PRISMA guidelines, five databases (Cochrane, Embase, Medline, PsycInfo, Web of Science), in addition to hand searches of reference lists and ProQuest Dissertations and Theses Global, were searched for studies that investigated evidence relating to the neurobiological and cognitive correlates of ARFID. Twelve papers met inclusion criteria.\n\nResults: Twelve studies met inclusion criteria for this systematic review with a total of n = 548 ARFID participants across all studies. Neurobiological studies (k = 6) highlighted differences in regions including orbitofrontal and prefrontal cortices, and, in acute cases, midline diencephalic regions. Cognitive studies (k = 6) findings highlighted impaired executive function, specifically related to cognitive flexibility, impulsivity, visual processing skills, central coherence and inhibition.\n\nConclusions: Research into the neurobiology of ARFID is nascent. The results of this review contribute to improved understanding of the possible underlying neurobiological and cognitive differences within ARFID, which in turn will inform translational research aimed at better understanding and treating individuals with this illness.",
