Autism and Anorexia – Examining the Correlation

Contributor: Jacquelyn Ekern, MS, LPC, President of Eating Disorder Hope

summerfield-336672_640It is clear that autism spectrum disorders (ASD) and anorexia nervosa (AN) have some similarities. Both groups demonstrate a lower capacity for empathy, difficulty set shifting and rigid attitudes. These traits often come across to most of us as “uptight” or “tightly wound” and “cold” or “impersonal”.

It is commonplace in our society to blame eating disorders on media hype worshipping “thinness” and environmental trauma, but underlying biological issues are not as frequently considered. What if the underweight, picky eater who gags when faced with certain foods has more going on than meets the eye?

What if she restricts her eating because she cannot tolerate ingesting many foods due to underlying autism spectrum disorder traits and not because of weight concerns or trauma?

The Array of Genetic and Environmental Factors

Most of us would agree that it is important to consider the wide array of both genetic and environmental factors that contribute to disordered eating. After all, we want to continue to develop increasingly effective empirically supported treatments to help anorexia sufferers find recovery and healing.

So, the exploration of the autism and anorexia correlation is both profoundly important and promising.

Alienation Coupled with Sensitivity

This difficulty reading and gauging social cues is also typical in autism spectrum disorders.

It makes sense that these difficulties would probably cause a person struggling with anorexia to become a bit hypersensitive to how they fit in with others.

Additionally, some studies have indicated that individuals with anorexia nervosa and autism both benefit from administration of oxytocin. Researchers found that these individuals become better able to read social cues and socialize more effectively.

The Role of Oxytocin in Treatment

What is Oxytocin? It is the hormone and neurotransmitter made famous for its role in the feeling of “being in love”. It is a brain chemical made in the hypothalamus and secreted by the pituitary gland. Let me assure you, this is one feel good brain chemical that is about as close to bliss as you will find!

So, perhaps a deficit in oxytocin is a significant contributing factor to anorexia in some individuals? And if so, how should our protocol for anorexia treatment change for these individuals?

Important questions and discussion on this topic are occurring among researchers and we have much hope that greater understanding of the neurobiology of anorexia, will result in more effective and sustained recovery from anorexia nervosa.
