Lecture 10- Eating disorders Flashcards
what is the difference and similarity between Anorexia nervosa and Bulimia Nervosa?
AN centers on restriction of food intake while BN centers on recurrent binge-eating accompanied by inappropriate compensatory behavior.
Both ED have unhealthy self-evaluation based on body image
What is the difference between Bulimia and Binge eating disorder?
Bulimia involves inappropriate compensatory behavior after episode of binge-eating such as purging.
BED does not involve regular use of inappropriate compensatory behavior
which other mental disorders are AN and BN most likely to be comorbid with?
Anxiety and depression
Give one example of a psychological feature in Anorexia Nervosa
Perfectionism
Feelings of ineffectiveness
Inflexible/rigid thinking
Overly restrained emotional expression
What are the 2 subtypes of AN and BN each?
AN: AN-R (Restrictive) and AN-BP (Binge purge)
BN: BN-P (Purge) and BN-NP (non-purge)
What is the difference between an eating disorder and feeding disorder
ED has more body image concerns as cause of disordered eating. FD is more concerned with problem of the food than the individual’s self-evaluation
Which 2 eating disorders must occur at least once per week for 3 months as a DSM5 criteria
BN and BED
what is are the 2 setbacks of Atypical Anorexia Nervosa
1) All criteria met but despite weight loss, Individual’s weight is wiithin/above normal weight range
2) Harder to detect as individual does not present as “underweight”
There are 3 types of OSFED stated in lect, what are they? And why are they classified as OSFED?
Atypical AN
Purging disorder
Night eating syndrome
Under what circumstances are Unspecified Feeding and Eating Disorder (UFED) diagnoses given? 2 types
1) When clinicians choose not to specify why criteria not met
2) Insufficient info to make a specific diagnosis (E.g. emergency room setting)
Give an example of a feeding disorder
Avoidant Restrictive Food Intake Disorder (ARFID)
Pica
Rumination disorder
Which disorder requires clinical attention if occurred with another mental health condition or pregnancy
Pica and Rumination disorder
What does the dual pathway transdiagnostic model of bulimia nervosa attribute binge eating to?
Result of restriction
Emotional regulation technique
What are the 5Ps in which risk factors of ED come together?
Predisposing factors- Contribute to vulnerability of prob
Precipitating- Factors that trigger presenting prob
Presenting- Current prob, symptoms + context
Perpetuating- Maintenance of presenting prob
Protective- Protect individual against prob worsening
A) Recurrent episodes of binge eating (size & time & loss of control)
B) Recurrent inappropriate compensatory behaviour to prevent weight gain
(e.g., Purging, laxatives/diuretics, fasting, excessive exercise)
C) Occurs at least once per week for 3 months
D) Self-evaluation unduly influenced by body shape and weight
E) Does not occur exclusively during AN episode
These are DSM criteria of which eating disorder?
Bulimia Nervosa
DSM criteria of Anorexia Nervosa
A) Persistent restriction of energy intake leading to low body weight
B) Intense fear of weight gain or persistent behaviour that interferes with weight gain
C) Disturbance in how weight/shape is perceived, undue influence of weight/shape on self-evaluation, or lack of recognition of seriousness of current low weight
Give one cognitive changes to AN
Mild deficits in executive functioning, memory, verbal & visuospatial processing
Can impede recovery – e.g. rigid thinking
Mostly improves with weight restoration
Cog + Health issues can severely impact adolescent development
What is the 5 DSM criteria of BED
A) Recurrent binge eating (size + time + loss of control)
B) Three or more of the following:
Eating more rapidly than normal
Eating until uncomfortably full
Eating large amount of food when not hungry
Eating alone because embarrassed or disgusted
Depressed or guilty after over-eating
C) Marked distress regarding binge eating
D) Occurs once per week, 3 months +
E) No regular use of inappropriate compensatory behaviours
What are the 3 similarities between Orthorexia and AN
Health risks/malnutrition from cutting foods
Rigid food rules and preoccupation with food
Interfering with normal functioning
There 6 possible aetiological factors to ED. Give 2 examples
1) Dieting
2) Personality factors- neuroticism, perfectionism, negative affect
3) Body dissatisfaction
4) Thin-ideal internalization
5) Family environment
6) Genetics
TRUE OR FALSE. Muslim fasting can lead to Avoidant Restrictive Food Intake Disorder (ARFID).
FALSE.
