Current Status of the Identification, Differential Diagnosis, and Psychological Treatment of Avoidant/Restrictive Food Intake Disorder.

Avoidant/restrictive food intake disorder (ARFID) occurs in patients of all ages, with certain populations at increased risk. When diagnosing ARFID, it is important to assess a range of ARFID symptoms that result in diminished dietary variety and/or intake (eg, food selectivity, fears of eating-related physical sensations, low appetite) and associated consequences (eg, psychosocial impairment, malnutrition) as well as symptoms of other disorders that may better account for ARFID symptoms. Although there are currently no "gold-standard" ARFID treatments, existing treatments to date involve regularization of eating, exposure to physical sensations and/or novel/feared foods, and caregiver/familial involvement when appropriate.
