Eating and Sleep Disorders
Eating Disorders: An Overview
• Two Major Types of DSM-IV-TR Eating
Disorders
– Anorexia nervosa and bulimia nervosa
– Severe disruptions in eating behavior
– Extreme fear and apprehension about
gaining weight
– Strong sociocultural origins – Westernized
views
Eating Disorders: An Overview (continued)
• Other Subtypes of DSM-IV-TR Eating
Disorders
– Binge eating disorder – Buffet diet!
• Obesity – A Growing Epidemic – not yet a
disorder but the side effects are diagnosed.
Can be on Axis III
Bulimia Nervosa: Overview and Defining
Features
• Binge Eating – Hallmark of Bulimia

laxatives
– Some exercise excessively, whereas
others fast
Bulimia Nervosa: Overview and Defining

– Purging subtype – Most common subtype
– Nonpurging subtype – About one-third of
bulimics
Bulimia Nervosa: Associated Features
• Associated Medical Features
– Most are within 10% of target body weight
– Purging methods can result in severe
medical problems

seizures, intestinal problems, permanent
colon damage
Bulimia Nervosa: Associated Features
(continued)
• Associated Psychological Features
– Most are over concerned with body shape
– Fear of gaining weight
– Most have comorbid psychological
disorders
Anorexia Nervosa: Overview and Defining
Features
• Successful Weight Loss – Hallmark of
Anorexia
– Defined as 15% below expected weight
– Intense fear of obesity and losing control
over eating
– Anorexics show a relentless pursuit of
thinness
– Often begins with dieting
Anorexia Nervosa: Overview and Defining
Features (continued)
• DSM-IV-TR Subtypes of Anorexia

– Experimental diagnostic category
– Engage in food binges without
compensatory behaviors
Binge-Eating Disorder: Overview and
Defining Features (continued)
• Associated Features
– Many persons with binge-eating disorder
are obese
– Concerns about shape and weight
– Often older than bulimics and anorexics
– More psychopathology vs. non-binging
obese people
Bulimia and Anorexia: Facts and Statistics
• Bulimia
– Majority are female
– Onset around 16 to 19 years of age
– Lifetime prevalence is about 1.1% for
females, 0.1% for males
– 6-8% of college women suffer from bulimia
– Tends to be chronic if left untreated
Bulimia and Anorexia: Facts and Statistics
(continued)
• Anorexia
– Majority are female and white

adolescence
– More chronic and resistant to treatment
than bulimia
• Both Bulimia and Anorexia Are Found in
Westernized Cultures
Causes of Bulimia and Anorexia: Toward an
Integrative Model

Binge Eating Disorder-DSM-5
A. Recurrent episodes of binge eating. An episode of binge eating is characterized
by both of the following:
1. eating, in a discrete period of time (for example, within any 2-hour period), an
amount of food that is definitely larger than most people would eat in a similar period
of time under similar circumstances
2. a sense of lack of control over eating during the episode (for example, 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:
1. eating much more rapidly than normal
2. eating until feeling uncomfortably full
3. eating large amounts of food when not feeling physically hungry
4. eating alone because of feeling embarrassed by how much one is eating
5. feeling disgusted with oneself, depressed, or very guilty afterwards
C.
Marked distress regarding binge eating is present.
D.
The binge eating occurs, on average, at least once a week for three months.
E.
The binge eating is not associated with the recurrent use of inappropriate
compensatory behavior (for example, purging) and does not occur exclusively
during the course Anorexia Nervosa, Bulimia Nervosa, or Avoidant/Restrictive Food
Intake Disorder.
Anorexia Nervosa- DSM-5
A. Restriction of energy intake relative to requirements leading to a significantly
low body weight in the context of age, sex, developmental trajectory, and
physical health. Significantly low weight is defined as a weight that is less
than minimally normal, or, for children and adolescents, less than that
minimally expected. (*Rewording of DSM-IV criterion to focus on behavior,
not refusal to maintain body weight)
B. Intense fear of gaining weight or becoming fat, or persistent behavior that
interferes with weight gain, even though at a significantly low weight.
(*Addition of behavioral clause, as many deny fear)
C. Disturbance in the way in which one's body weight or shape is experienced,
undue influence of body weight or shape on self-evaluation, or persistent
lack of recognition of the seriousness of the current low body weight.
(*Criterion D – Amenorrhea – deleted; many exhibit some menstrual activity,
does not apply to pre-menarchal females, post-menarchal females, those
taking modern oral contraceptives, and males)
Specify current type: (*Due to cross-over complication in current episode subtyping in the DSM-IV, current types are now specified “during the last three
months”)
Restricting Type: during the last three months, the person has not engaged in
recurrent episodes of binge eating or purging behavior (i.e., self-induced
vomiting or the misuse of laxatives, diuretics, or enemas)
Binge-Eating/Purging Type: during the last three months, the person has
engaged in recurrent episodes of binge eating or purging behavior (i.e., selfinduced vomiting or the misuse of laxatives, diuretics, or enemas)
Bulimia Nervosa-DSM-5
A. Recurrent episodes of binge eating. An episode of binge eating is
characterized by both of the following:
1. Eating, in a discrete period of time (for example, within any 2-hour
period), an
amount of food that is definitely larger than most
people would eat during a
similar period of time and under
similar circumstances.
2. A sense of lack of control over eating during the episode (for
example, a feeling
that one cannot stop eating or control what or
how much one is eating).
B. Recurrent inappropriate compensatory behavior 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. (*change from
twice/week for past two months)
D. Self-evaluation is unduly influenced by body shape and weight.
E. The disturbance does not occur exclusively during episodes of
anorexia nervosa.
(*Removal of purging/non-purging subtype)

Feeding or Eating Conditions Not Elsewhere
Classified – DSM-5
Originally termed Eating Disorder NOS
Atypical Anorexia Nervosa - All criteria for AN are met, except that, despite significant weight
loss, the individual’s weight is within or above the normal range.
Subthreshold Bulimia Nervosa (low frequency or limited duration) - All criteria for BN are met,
except that the binge eating and inappropriate compensatory behaviors occur, on average, less
than once a week and/or for less than for 3 months.
Subthreshold Binge Eating Disorder (low frequency or limited duration) -All criteria for BED are
met, except that the binge eating occurs, on average, less than once a week and/or for less than
for 3 months.
Purging Disorder - Recurrent purging behavior to influence weight or shape (self-induced
vomiting, misuse of laxatives, diuretics, or other medications), in the absence of binge eating.
Self-evaluation unduly influenced by body shape or weight or there is an intense fear of gaining
weight or becoming fat.
Night Eating Syndrome - Recurrent episodes of night eating, as manifested by eating after
awakening from sleep or excessive food consumption after the evening meal. There is
awareness and recall of the eating. The night eating is not better accounted for by external
influences such as changes in the individual’s sleep/wake cycle or by local social norms. The
night eating is associated with significant distress and/or impairment in functioning. The
disordered pattern of eating is not better accounted for by Binge Eating Disorder, another
psychiatric disorder, substance abuse or dependence, a general medical disorder, or an effect
of medication.
Other Feeding or Eating Condition Not Elsewhere Classified - Residual category for clinically
significant problems meeting the definition of a Feeding or Eating Disorder but not satisfying
the criteria for any other Disorder or Condition.

Have a bed time routine – same time, and strive for the same number of hours
each night – “in and out” at the same time.
Determine your “standard” number of hours for sleep – it changes with age
Be careful of stimulants 2 hours before bed time
No alcohol, heavy food, smoking before 4-6 hours before bed
Your bed is for two purposes – one is sleep – the other….! Do not eat, watch
TV, do papers, or online work in bed
Do not exercise two hours before bed time
Keep room cool; dark
Set up “white noise” - if outside noises bother you
Identify stressors and try to cope with them
Get up if you do not sleep in 20-30 minutes
Get out in the sunshine 20 minutes per day
Relaxing activities 30 minutes before bed – relaxation, meditation, Dr. Seuss;
music (soft);
Snore? Sleepy all day? Taking frequent naps? New meds? Check it out!
Bedrooms are “No Tech Zones”!

Sleep Disorders
Kleine Levin Syndrome
A. The patient experiences recurrent episodes of excessive sleep
(>11 hours/day).
B. Episodes occur at least once a year, and are generally 2 days to 4
weeks in duration.
C. During episodes, when awake, cognition is abnormal with feeling
of unreality or confusion. Behavioral abnormalities such as
megaphagia or hypersexuality may occur in some episodes.
D. The patient has normal alertness, cognitive functioning, and
behavior between the episodes.
E. The condition is not better accounted for by another mental
disorder (e.g, mood disturbance), and is not due to the direct
physiological effects of a substance (e.g., a drug of abuse, a
medication) or another general medical condition (e.g. a metabolic
disorder).
Sleep Disorders
Obstructive Sleep Apnea Hypopnea Syndrome (previously Breathing
Related Sleep Disorder)
A. Symptoms of snoring, snorting/gasping or breathing pauses
during sleep AND/OR
B. Symptoms of daytime sleepiness, fatigue, or unrefreshing sleep
despite sufficient opportunities to sleep and unexplained by
another medical or psychiatric morbidity AND
C. Evidence by polysomnography of 5 or more obstructive apneas or
hypopneas per hour of sleep OR
D. Evidence by polysomnography of 15 more obstructive apneas
and/or hypopneas per hour of sleep.
Coding note: Also code sleep-related breathing disorder on Axis III.
Sleep Disorders
Primary Central Sleep Apnea (previously Breathing Related Sleep
Disorder)
A. The patient reports at least one of the following:
1. excessive daytime sleepiness
2. frequent arousals and awakenings during sleep or insomnia
complaints
3. awakening short of breath
B. Polysomnography shows five or more central apneas per hour of
sleep
C. The disorder is not better explained by another current sleep
disorder, medical or neurological disorder, medication use, or
substance use disorder.
Sleep Disorders
Primary Alveolar Hypoventilation (previously Breathing Related Sleep
Disorder)
A. Polysomnographic monitoring demonstrates episodes of shallow
breathing longer than 10 seconds in duration associated with
arterial oxygen desaturation and frequent arousals from sleep
associated with the breathing disturbances or bradytachycardia. Note: although symptoms are not mandatory to
make this diagnosis, patients often report excessive daytime
sleepiness, frequent arousals and awakenings during sleep, or
insomnia complaints.
B. No primary lung diseases, skeletal malformations, or peripheral
neuromuscular disorders at affect ventilation are present.
C. The disorder is not better explained by another current sleep
disorder, medical or neurological disorder, mental disorder,
medication use, or substance use disorder.
Sleep Disorders
Rapid Eye Movement Behavior Disorder
A. Repeated episodes of arousal during sleep associated with vocalization and/or
complex motor behaviors which may be sufficient to result in injury to the individual
or bedpartner.
B. These behaviors arise during REM sleep and therefore usually occur greater that 90
minutes after sleep onset, are more frequent during the later portions of the sleep
period, and rarely occur during daytime naps.
C. Upon awakening, the individual is completely awake, alert, and not confused or
disoriented.
D. The observed vocalizations or motor behavior often correlate with simultaneously
occurring dream mentation leading to the report of “acting out of dreams”.
E. The behaviors cause clinically significant distress or impairment in social or other
important areas of functioning – particularly pertaining to distress to bedpartner or
injury to self or bedpartner.
F. At least one of the following is present: 1) Sleep related injurious, potentially
injurious, or disruptive behaviors arising from sleep and 2) Abnormal REM sleep
behaviors documented by polysomnographic recording
G. REM sleep without atonia on polysomnographic recording
H. The disturbance is not due to the direct physiological effects of a substance (e.g., a
drug of abuse, a medication) or a general medical condition.
Sleep Disorders
Restless Legs Syndrome
A. Each of the following criteria must be met.
The patient reports:
1. An urge to move the legs usually accompanied or caused by uncomfortable and unpleasant
sensations in the legs (or for pediatric RLS the description of these symptoms should be in the
child's own words).
2. The urge or unpleasant sensations begin or worsen during periods of rest or inactivity. 3.
Symptoms are partially or totally relieved by movement
4. Symptoms are worse in the evening or at night than during the day or are present only at
night or in the evening. (The worsening occurs independently of any differences in activity,
which is important for pediatric RLS as children are sitting much of the day at school).
B. These symptoms are accompanied by significant distress or impairment in social, occupational,
academic, behavioral or other important areas of functioning indicated by the presence of at
least one of the following:
1. Fatigue or low energy, 2. Daytime sleepiness, 3. Cognitive impairments (e.g., attention,
concentration, memory, learning), 4. Mood disturbance (e.g., irritability, dysphoria, anxiety), 5.
Behavioral problems (e.g., hyperactivity, impulsivity, aggression), 6. Impaired academic or
occupational function, 7. Impaired interpersonal/social functioning
C. Frequency: Remains under discussion pending consideration of secondary data analysis
D. Duration: Remains under discussion pending considerations of secondary data analysis.
E. The occurence of the above symptoms are not solely accounted for as symptoms primary to
another medical or behavioral condition (e.g., positional discomfort, leg cramps, habitual foot
tapping, arthritis, neuropathic pain and peripheral ischemia).
F. The sleep difficulty occurs despite adequate age-appropriate circumstances and opportunity for
sleep.

Sleep Disorders
Circadian Rhythm Sleep Disorder - Advanced Sleep Phase Type
A. Persistent or recurrent pattern of sleep disruption leading to

breathing, and sweating during an episode.
2. Sleepwalking - Repeated episodes of rising from bed during sleep and walking about,
usually occurring during the first third of the major sleep episode. While sleepwalking, the
person has a blank, staring face, is relatively unresponsive to the efforts of others to
communicate with him or her, and can be awakened only with great difficulty.
3. Sleep terrors - Recurrent episodes of abrupt awakening from sleep, usually occurring
during the first third of the major sleep episode and beginning with a panicky scream.

breathing, and sweating, during each episode.
C. Relative unresponsiveness to efforts of others to comfort the person during the episode.
D. No detailed dream is recalled and there is amnesia for the episode.
E. The episodes cause clinically significant distress or impairment in social, occupational, or

D. The sleep difficulty occurs at least three nights per week.
E. The sleep difficulty is present for at least three months.
F. The sleep difficulty occurs despite adequate age-appropriate circumstances and opportunity for sleep. Duration:
1. Acute insomnia (<1 month)

Sleep Disorders
Primary Hypersomnia/Narcolepsy without cataplexy
A. The predominant complaint is unexplained hypersomnia (excessive sleep) or/and
hypersomnolence (sleepiness in spite of sufficient nocturnal sleep), for at least 3
months, occurring 3 or more times per week.
1. Hypersomnia (excessive sleep) is defined by a prolonged nocturnal sleep episode
or daily sleep amounts (>9 hours/day).
2. Hypersomnolence is defined by excessive daytime sleepiness with recurrent
daytime naps or lapses into sleep that occurs daily or almost daily over at least the
last 3 months (when the patient is untreated) and daily sleep amounts > 6 hours. To
document hypersomnolence, the Multiple Sleep Latency Test must show a mean
sleep latency below 8 minutes, with or without Sleep Onset REM Periods
(SOREMPs). If the patient has more than 2 SOREMPs, the condition may be called
“narcolepsy without cataplexy”.
B. The sleep periods are non-restorative (unrefreshing) or so prolonged in length that
this causes clinically significant distress or impairment in social, occupational, or
other important areas of functioning.
C. The hypersomnia is not better accounted for by insomnia and does not occur
exclusively during the course of another Sleep Disorder (e.g., Narcolepsy with
Cataplexy, Sleep-Related Breathing Disorder, Circadian Rhythm Sleep Disorder, or a
Parasomnia) and cannot be accounted for by an inadequate amount of sleep.
D. The disturbance does not occur exclusively during the course of another mental or
medical disorder but may occur simultaneously with these disorders.
E. The disturbance is not due to the direct physiological effects of a substance (e.g., a
drug of abuse, a medication).
Clinically Comorbid Conditions:
Mental/Psychiatric Disorder (specify)
Medical Disorder (specify)
Sleep Disorders
• Narcolepsy/Hypocretin Deficiency
A. Recurrent daytime naps or lapses into sleep that occurs daily or
almost daily over at least the last 3 months (when the patient is
untreated).
B. The presence of one or both of the following:
1. Cataplexy defined as brief (a few seconds to 2 minutes)
episodes of sudden bilateral loss of muscle tone with maintained
consciousness, most often in association with laughter or
joking. These episodes must occur at least a few times per month
providing the patient is untreated for this symptom.
2. Hypocretin deficiency, as measured using CSF hypocretin-1
immunoreactivity measurements (<1/3 of normal reference
values).
C. Do not occur exclusively during the course of another mental or
medical disorder but may occur simultaneously with these
disorders.
Sleep Disorders
Circadian Rhythm Sleep Disorder
A. A persistent or recurrent pattern of sleep disruption leading to excessive sleepiness,
insomnia, or both that is primarily due to an alteration of the circadian system or to a
misalignment between the endogenous circadian rhythm and the sleep-wake schedule
required by a person’s physical environment or social/professional schedule.
B. The sleep disturbance causes clinically significant distress or impairment in social,
occupational, or other important areas of functioning.
Specify type:
Delayed Sleep Phase Type: a persistent or recurrent pattern of delayed sleep onset and
awakening times, with an inability to fall asleep and awaken at a desired or conventionally
acceptable earlier time
Advanced Sleep Phase Type: a persistent or recurrent pattern of advanced sleep onset
and awakening times, with an inability to remain awake and asleep until the desired or
conventionally acceptable later sleep and wake times
Irregular Sleep –Wake Type: a temporally disorganized sleep and wake pattern, so that
sleep and wake periods are variable throughout the 24 hour period.
Free-Running Type: a persistent or recurrent pattern of sleep and wake cycles that are not
entrained to the 24 hour environment, with a daily drift (usually to later and later times) of
sleep onset wake times
Jet Lag Type: sleepiness and alertness that occur at an inappropriate time of day relative
to local time, occurring after travel across time zone
Shift Work Type: insomnia during the major sleep period and/or excessive sleepiness
(including inadvertent sleep) during the major awake period associated with shift work
schedule o(i.e., requiring unconventional work hours) of at least one month
Clinically Comorbid Conditions:
1. Mental/Psychiatric Disorder (specify)
2. Medical Disorder (specify)
Sleep Disorders
Nightmare Disorder
A. Repeated awakenings from the major sleep period or naps with
detailed recall of extended and extremely dysphoric dreams,
usually involving active efforts to avoid threats to survival,
security, or physical integrity. The awakenings generally occur
during the second half of the sleep period.
B. On awakening from the dysphoric dreams, the person rapidly
becomes oriented and alert (in contrast to the confusion and
disorientation seen in Sleep Terror Disorder and some forms of
epilepsy).
C. The dream experience, or the sleep disturbance resulting from the
awakening, causes clinically significant distress or impairment in
social, occupational, or other important areas of functioning.
D. The nightmares do not occur exclusively during the course of
another mental disorder (e.g., a delirium, Posttraumatic Stress
Disorder) and are not due to the direct physiological effects of a
substance (e.g., a drug of abuse, a medication) or a general
medical condition.
