Neurodiversity-affirming eating disorder care: insights into addressing co-occurring autism and eating disorders

Eating disorders, particularly anorexia nervosa and avoidant-restrictive food intake disorder, commonly co-occur with autism. Many autistic people with eating disorders face delays and challenges in assessment and treatment because their particular needs are not understood. The aim of this narrative review is to introduce the concept of neurodivergence-affirming eating disorder care and to review recent scientific research on this topic.

Some of the unique challenges that autistic individuals with eating disorders face include sensory processing differences, communication barriers, and unmet support needs. Neurodiversity-affirming care challenges structural ableism by emphasizing co-designing care with autistic experts by experience. Neurodiversity-affirming practitioners presume that their clients are autonomous and competent. When providing care, they respect different communication styles, tailor support to their client's individual needs and strengths, and seek to foster a positive autistic identity. This involves respecting autistic eating behaviours, providing timely assessment and support, individualized treatment goals, and carefully considering communication and sensory needs.

Eating disorder service providers often have a hard time understanding their autistic clients. This can contribute to poor eating disorder treatment outcomes. Neurodiversity-affirming practitioners seek insight from the autistic community and participatory research to improve eating disorder services for their clients.
