Calorie Restriction, Anorexia Nervosa, and Memory Gaps

This post has been translated into Russian by Polina here.

I have often heard anorexia nervosa sufferers complain of “memory gaps,” particularly during the times they were really sick. As if they weren’t really there.  It can be scary and unnerving, to say the least. A few months ago, a Tumblr user asked me about this:

Hi Tetyana, I’m not sure if this is merely based on my own subjective experience of if there is any grounding at all, but I was wondering if there could perhaps be a link between EDs and a sort of memory loss. It’s hard to describe but I definitely seem to have huge “gaps” in my memory of during that time, as if I selectively block things out. I have limited inaccurate knowledge with regards to memory on a molecular/neurological basis so I do not know if there’s anything there. Perhaps with calorie

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 →
