Eating Disorders
Becoming more and more understood from a neuropsychological framework.
Pro-ana: online communities of people who are committed to starvation and being excessively thin.
Also seen with drug addictions as well (ways to get the most high etc).
Distortion of persons actual body what they perceive their body to look like. It can also reach like
a delusional level. They are renowned for their lack of insight: similar to Body Dysmorphic Disorder
in that insight is very limited.
Treatment usually occurs after the individual is hospitalized. Typically seen in-patient program and
then out-patient program. Often suffer from anxiety and depression. Usually only during times of
stress when the eating habits come back
The damage to the body can be enduring even after treatment.
Anorexia afflicts mostly young women
10-15% tend to be male
Male Analog??? Men convinced that they need to be more muscular: obsessions about being more
muscular. May be some kind of flipping; the opposite of anorexia
If you ask women to ideal male body looks like middle build even though men think its the more
muscular male. If you ask males ideal female it would also be the middle build whereas females think
males prefer the skinnier one. Calibration problem
Shows up primarily 16-20 years. Can happen in kids as young as 10. Rarely happens past age 20
Generally find many of the cognitions around the eating disorder are still there but have high control
over the behavioural manifestation.
DSM Criteria
Refusal to maintain body weight (determined through Body Mass Index)
Intense fear or gaining weight or becoming fat
Distortions in perception of one’s body weight
Loss of menstrual criteria core characteristic. Cannot be formally diagnosed without that. However
will be changing in the new DSM
Types of Anorexia

Restricting type: some may go days without eating. Just enough calories to pretty much function.
Binge Type: self-induced vomiting, laxatives etc. They will still be 15% below a healthy body weight
whereas people with Bulimia will be at a normal weight or just a bit over. Also missing their period. This
tends to be the more severe presentation of anorexia.
These behaviours are safety behaviours
Trigger = eating food/seeing food/thinking about being fat/smelling food/reading about food can make
them want to engage in their compulsion (vomiting)
Thought = going to get fat
Emotion = sadness
Physical = fight/flight
Behaviour = release vomiting
Anorexia affects whole body
If your ions and electrolytes are off it can easily make your heart stop
If not eating/drinking; urine can get very concentrated and acidic kidney stones
Just know that they are multi-factorial; many systems buy it and know the main systems that
would be effected *EXAM*
Gastrointestinal complication acid reflux, hard to re-start the systems slowly
Bulimia
Eating a lot and lack of control over eating
Intake of calories can be pretty substantial superhuman amounts of calories
At least twice a week for 3 months
Don’t see same profound delusional thinking in Bulimia. It can be there but its more like really
unhealthy preoccupation. Can even be like an obsession but not delusional.
Animal species stop eating when they feel under threat or nervous biological underpinnings
perhaps of human eating disorders. Take mice: easily trained to eat cheerios, sweetened water etc.
Train it to eat a favourite treat if you put the mouse in a new cage with that treat; they monitor the
food firs, hang out in the cage in the corner, they don’t just automatically start eating. But if you give
them an SSRI they will immediately approach the food.

Evolutionarily: our fear system is really stupid: cannot discriminate between what’s new and what’s
dangerous.
Eating disorders often come out of chaotic upbringings and times of stress. Not always abuse but can
be a feature of eating disorders when the person has endured abuse.
Ubiquatey Book
Types of Bulimia
Non-purging type: excessive exercise variant generally prescribe exercise for anxiety and
depression. If they exercise compulsively it becomes a safety behaviour and often they don’t
recognize it as so. But can sometimes re-train them to have a healthier relationship with it.
Routines that they come up with and hide from family is significant. Can become very ritualized.
Eating disorders are just anxiety disorders focused on body issues. Can also be used as a coping
mechanism for trauma.
Medical Complications
Laxative use: your body can become addicted –dependant on them. The stomach and the intestines
(their own nervous system) and that nervous system can go to sleep
Binge Eating Disorder
Resembles bulimia but doesn’t engage in purging, fasting or excessive exercise so taking in 10,000
calories in one sitting and then not getting rid of it.
A lot of obesity that comes along here
Underlying anxiety, depression, trauma, often associated with Cluster B traits (BPD, histrionic
personality disorder) and the binge = veiled self harm much in the way cutting is.
Contributors to the Eating Disorder
Multi-factorial
Genetic predisposition inherited in a practicable manor
An anxiety or mood related issue that occurs in the family (in mother GAD, daughter as an eating
disorder) manifests in different ways in different people but overall pre disposition is there
Very apt to have really pessimistic negative thinking; very irritable, angry kind of depression
Predisposition to depression avoidant coping style: that’s what gets depression up and running in
the first place
