Why is early intervention in eating disorders recommended?
Has better prognosis
Why is intervention is general for eating disorders recommended?
- Eating disorders have a high mortality rate
- 80% of ED patients will reach remission
What increases in severity as time goes on?
ED’s, there is often lots of pre-contemplation prior to seeking treatment; they go through denial, have lack of insight
Which type of ED has the highest mortality rate?
Anorexia Nervosa
What kind of treatments to ED patients seek prior to ED help?
-Weight loss

Counterintuitive to the root of the problem
Describe the three key features of AN
1) Restriction of energy intake leading to a significant weight-loss
2) Intense fear of gaining weight or becoming fat
3) Disturbances in self-body image, lack of recognition of the seriousness of their body weight
(T/F) To have anorexia, patients must have a significantly low weight
F, they must have experienced significant weight-loss, which doesn’t necessarily mean they are at a low weight (i.e. going form BMI of 30-22)
When does someone recovering from and ED begin to see their lack of recognition in the own seriousness of their ED?
Once they stat re-gaining weight, sometimes their cognitive rigidity begins to soften
What are the two sub-types of AN?

- Binge-eating/purging type
BMI 17 + AN=
Mild
BMI 16-16.99 AN =
Moderate
BMI 15-15.99 AN =
Severe
BMI <15 AN +
Extreme
In the prognosis of AN, ___ of patients will normalize weight
2/3
In prognosis of AN, patients with illness before 17 y/o achieve a ___ outcome than adult onset

Explain how restrictive eating leads to binge-eating
Restrictive behaviours will lead to hunger, stress, negative emotions which will drive binge eating. After the binge, feelings of guilt, fear to gain weight and self disgust will ensue.
