Is Anorexia Nervosa a Version of Autism Spectrum Disorders?

Patients with anorexia nervosa often have difficulties recognizing and regulating emotions. This  conclusion that is largely based on data from  common tests such as Reading the Mind in the Eyes assessing  emotion recognition, and questionnaires like Difficulties in Emotion Regulation Scale (DERS) assessing emotion regulation (see my post here).  Although that study compared currently ill patients with healthy controls (thus raising the possibility that the resulting data was due to the effects of starvation or due to the chronic nature of the ED  in the sample, ~7.5 year on average), there is some evidence that some of these difficulties persist post-recovery.

Individuals with autism (ASD, or autism spectrum disorders) also have difficulties with emotion recognition and regulation, leading some investigators to hypothesize that AN and ASD may share common etiology. Providing further support for this hypothesis are studies suggesting that AN might be overrepresented in ASD … Continue reading →

Devil in the Details: Can Poor Cognitive Function be Attributed to Anorexia Nervosa Patients’ Obsession with Detail?

Hi all, Gina here, again. This article is short and sweet, as is my post. I’m becoming increasingly interested in some of the more cognitive aspects of eating disorders and seeing as my background on the subject is pretty limited (re: none, although I’m taking a cognitive science class this term), I was hoping to generate some discussion /or references from readers that I could incorporate into further posts. Cheers!

It has long been suggested that people with eating disorders (in this case, specifically anorexia nervosa) display some core deficits in cognitive ability — namely impairments in executive function (Fassino et al., 2002; Pendleton Jones et al., 1991; Tchanturia et al., 2001, 2002, 2004).

If you’re like me and don’t study cognitive science, executive function basically means that people with AN show abnormal mental rigidity, working memory, capacity to manage impulsive responses (response disinhibition) and abstraction skills (i.e. abstract … Continue reading →
