ED Flashcards
(15 cards)
What are the key behaviors associated with eating disorders?
Restrictive eating
Binge eating
Compensatory behaviors (e.g., purging or excessive exercise)
What are the symptoms of Anorexia Nervosa (AN)?
Significantly low body weight
Intense fear of weight gain
Body-image disturbance
What are the subtypes of Anorexia Nervosa (AN)?
Restricting Type: No binge eating or purging, weight loss from dieting or excessive exercise
Binge Eating/Purging Type: Involves recurrent binge eating or purging behaviors
What are the symptoms of Bulimia Nervosa (BN)?
Recurrent binge eating followed by compensatory behaviors (e.g., vomiting, laxatives)
Occurs at least once a week for three months
What are the symptoms of Binge Eating Disorder (BED)?
Episodes of binge eating without compensatory behaviors
Feeling guilt, disgust, or depression after binge eating
What neurobiological factors are associated with eating disorders?
Serotonin (5-HT), opioid, and dopaminergic systems are implicated.
Reward System: Overactive reward systems may increase risk for binge eating; chronic overeating can alter reward pathways.
Fairburn’s cognitive model for BN
Clearly identifies binge eating as a response to periods of restricting or
dieting, even when total intake is not abnormally low and even when
significant weight is not lost
GENETIC RISK FACTORS
Genetic factors account for 50% or more of the variance in AN, BN, and
BED in adulthood
Developmental twin studies show that in females, overall levels of eating
disorder symptoms exhibit no genetic influences before puberty, but significant
genetic effects are observed from mid-puberty on
some genes that have promises
serotonin, neurotrophic, estrogen receptor, dopamine
Fairburns CBT
Goalà address core cognitive features (i.e., overconcern with
weight and shape) that maintain eating-related pathology across the
spectrum must be addressed
Appetite awareness training
Goal is to shift attention away from the typical overfocus on
food type and promote reliance instead on internal appetite
cues (both hunger and fullness) to guide eating decisions
specific treatment for AN
Target weight restoration first
Maudsley method is the most well-established family-based treatment
(FBT) for adolescents with AN
3 phases of FBT
First Phase: Assists parents in taking charge of weight restoration in their adolescent with AN. This represents a significant shift from previous parental responses.
Second Phase: Focuses on helping the adolescent regain control of eating once healthy patterns have been reestablished under parental supervision.
Third Phase: Explores adolescent developmental issues, particularly those impacted by AN.
¡ Specialist supportive individual therapy (SSIT)-
reducing fears of losing control over the process of
weight restoration
- superior to other methods
