4 Eating and Sleep-Wake Disorders Flashcards
In _____, out-ofcontrol eating episodes, or binges, are followed by self-induced vomiting, excessive use of laxatives, or other attempts to purge (get rid of) the food.
bulimia nervosa
In _____, the person eats nothing beyond minimal amounts of food, so body weight sometimes drops dangerously.
_____ has the highest mortality rate of any psychological disorder reviewed in this book, including depression.
anorexia nervosa
In _____ disorder, individuals may binge repeatedly and find it distressing, but they do not attempt to purge the food.
binge-eating
In these (eating) disorders, unlike most others, the strongest contributions to etiology seem to be _____ rather than psychological or biological factors.
sociocultural
_____ is not considered an official disorder in the DSM, but we consider it here because it is thought to be one of the most dangerous epidemics confronting public health authorities around the world
today.
Obesity
A. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:
- Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most individuals would eat in a similar period of time under similar circumstances
- A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).
B. Recurrent inappropriate compensatory behaviors in order to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise.
C. The binge eating and inappropriate compensatory behaviors both occur, on average, at least once a week for 3 months.
D. Self-evaluation is unduly influenced by body shape and weight
E. The disturbance does not occur exclusively during episodes of anorexia nervosa.
Specify if:
In partial remission: After full criteria for _____ were previously met, some, but not all, of the criteria, have been met for a sustained period of time.
In full remission: After full criteria for _____ were previously met, none of the criteria have been met for a sustained period of time.
Specify current severity:
The minimum level of severity is based on the frequency of inappropriate compensatory behaviors (see below). The level of severity may be increased to reflect other symptoms and the degree of functional disability.
Mild: An average of 1-3 episodes of inappropriate compensatory behaviors per week.
Moderate: An average of 4-7 episodes of inappropriate compensatory behaviors per week.
Severe: An average of 8-13 episodes of inappropriate compensatory behaviors per week.
Extreme: An average of 14 or more episodes of inappropriate compensatory behaviors per week.
Bulimia Nervosa
The hallmark of _____ is eating a larger amount of food—typically, more junk food than fruits and vegetables—than most people would eat under similar circumstances
bulimia nervosa
An individual with bulimia usually presents with additional psychological disorders, particularly _____ disorders.
anxiety and mood
For a number of years, one prominent theory suggested that eating disorders are simply a way of expressing _____. But most evidence indicates that _____ follows bulimia and may be a reaction to it.
depression
In summary, bulimia seems strongly related to anxiety disorders and somewhat less so to mood and _____ disorders.
substance use
A. Restriction of energy intal17kg/m2
Moderate: BM116-16.99 kg/m2
Severe: BM115-15.99 kg/m2
Extreme: BMI < 15 kg/m2
Anorexia Nervosa
Individuals with anorexia nervosa (which literally means a “_____”— an incorrect definition because appetite often remains healthy) differ in one important way from individuals with bulimia.
nervous loss of appetite
The major difference seems to be whether the individual is successful at losing weight.
People with anorexia are _____ of both their diets and their extraordinary control.
People with bulimia are ashamed of both their eating issues and their lack of control.
proud
Although decreased body weight is the most notable feature of anorexia nervosa, it is not the core of the disorder. Many people lose weight because of a medical condition, but people with anorexia have an _____ of obesity and relentlessly pursue thinness.
intense fear
DSM-5 specifies two subtypes of anorexia nervosa. In the restricting type, individuals diet to limit calorie intake; in the _____ type, they rely on purging
binge-eating–purging
Unlike individuals with bulimia, _____ anorexics binge on relatively small amounts of food and purge more consistently, in some cases each time they eat.
binge-eating–purging
One common medical complication of anorexia nervosa is cessation of menstruation (_____), which also occurs relatively often in bulimia
amenorrhea
Also, it is relatively common to see _____, downy hair on the limbs and cheeks.
lanugo
Interestingly, one anxiety disorder that seems to co-occur often with anorexia is _____.
obsessive-compulsive disorder (OCD)
_____ is also common in individuals with anorexia nervosa, and, in conjunction with anorexia, is a strong predictor of mortality, particularly by suicide.
Substance abuse
A. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:
- Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most people would eat in a similar period of time under similar circumstances.
- A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).
B. The binge-eating episodes are associated with three (or more) of the following:
- Eating much more rapidly than normal.
- Eating until feeling uncomfortably full.
- Eating large amounts of food when not feeling physically hungry.
- Eating alone because of feeling embarrassed by how much one is eating.
- Feeling disgusted with oneself, depressed, or very guilty afterward.
C. Marked distress regarding binge eating is present.
D. The binge eating occurs, on average, at least once a week for 3 months.
E. Binge eating is not associated with the recurrent use of inappropriate compensatory behavior as in bulimia nervosa and does not occur exclusively during the course of bulimia nervosa or anorexia nervosa.
Specify if:
In partial remission: After full criteria for binge-eating disorder were previously met, binge eating occurs at an average frequency of less than one episode per week for a sustained period of time.
In full remission: After full criteria for binge-eating disorder were previously met, none of the criteria have been met for a sustained period of time.
Specify current severity:
The minimum level of severity is based on the frequency of episodes of binge eating (see below). The level of severity may be increased to reflect other symptoms and the degree of functional disability.
Mild: 1-3 binge-eating episodes per week.
Moderate: 4-7 binge-eating episodes per week.
Severe: 8-13 binge-eating episodes per week.
Extreme: 14 or more binge-eating episodes per week
Binge-Eating Disorder
