2 Historical Review Accounts of fasting Catholic Saints in 14 th century Anorexia nervosa introduced by Sir William Gull in 1874 Gerald Russell named Bulimia nervosa in Minnesota Starvation Study Ancel Keys, et al Recruited 36 conscientious objectors in 1944 During 24 week starvation period, diet adjusted to achieve loss of 25% of body weight Followed by rehabilitation phase Physical Effects of Starvation Weakness Cold sensitivity Decrease in: temperature pulse respiration Edema Hair loss Decreased sexual interest Poor concentration Fatigue Sleep problems

3 Behavioral Effects of Starvation Preoccupation with food Social withdrawal Depression, emotional distress Eating rituals Food cravings Vicarious pleasure in watching others eat Increased fluid consumption Compulsive gum chewing Hoarding, obsessiveness What causes eating disorders? Cultural influences Gender Genetic factors Psychosocial factors **Families do not cause eating disorders Psychosocial risk factors Perfectionism Low self esteem Anxiety and mood disorders Negative life events

4 DSM 5: Feeding and Eating Disorders Persistent disturbance of eating or eating related behaviors resulting in altered consumption or absorption of food that significantly impairs physical health or psychosocial functioning Diagnostic criteria provided for Anorexia Nervosa Bulimia Nervosa Binge-Eating Disorder Avoidant/Restrictive Food Intake Disorder (ARFID) Pica Rumination Disorder Unspecified or Other Specified Eating Disorder Anorexia Nervosa Significantly low body weight Mild: BMI >17 Moderate: BMI Severe: BMI Extreme: BMI <15 Fear of fatness or persistent behavior that interferes with weight gain Body image disturbance or persistent lack of recognition of the seriousness of the current low body weight Restricting type or binge-eating/purging type Anorexia Nervosa cont. Peak age of onset Lifetime prevalence 0.9% for women in U.S. High rates of mood and anxiety disorders Highest mortality rate of any psychiatric disease 5-10% 10 year mortality rate Mortality rate increases 5.6% per decade that an individual remains ill

5 Bulimia Nervosa Recurrent binge eating Recurrent purging (vomiting, misuse of laxatives, diuretics or other medications, fasting or excessive exercise) Episodes of binge eating/purging on average at least 1 time per week for 3 months Over-evaluation of shape and weight Not anorexia nervosa Bulimia Nervosa cont. Peak age of onset 16 to 22 2 to 3 % of young women Elevated rates of depression, bipolar disorder, anxiety disorders, substance use disorders, and personality disorders Binge-Eating Disorder Recurrent episodes of bring eating Episodes are associated with 3 (or more) of: 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 about how much is consumed Feeling disgusted, depressed or very guilty after a binge Marked distress regarding binge eating is present Occurs, on average, at least 1 time/week for 3 months Not bulimia or anorexia

6 Avoidant/Restrictive Food Intake Disorder (ARFID) Eating or feeding disturbance disallowing appropriate nutritional and/or energy needs associated with one (or more) of: Significant weight loss Significant nutritional deficiency Dependence on enteral feeding or oral supplements Marked interference with psychosocial functioning Not better explained by lack of available food or associated culturally sanctioned practice Not anorexia or bulimia and there is no evidence of a disturbance in one s body image Not attributable to a concurrent medical condition or mental disorder Avoidant/Restrictive Food Intake Disorder (ARFID) Differentiating the feeding disturbance (examples): Apparent lack of interest in eating or food Avoidance based on the sensory characteristics of food Concern about aversive consequences of eating GI problems/pain Vomiting Choking Unspecified Feeding or Eating Disorders (307.50) Clinically significant distress or impairment in, social, occupational, or other important areas of functioning predominate but do not meet full criteria for any of the disorders Used when the clinician chooses not to specify the reason criteria are not met Includes presentations in which there is insufficient information (e.g., in emergency room settings)

7 Other Specified Feeding or Eating Disorder (307.59) Atypical AN (all criteria for AN are met, except despite the significant weight lose the individuals weight is within or above the normal range) Subclinical BN or BED (all criteria for BN are met, not meeting frequency criteria) Purging Disorder (recurrent purging to influence weight or shape, and may include misuse of laxatives and other medications in the absence of binge-eating) Night Eating Syndrome (recurrent episodes of night eating causing distress and impairment and not better explained by other disorders or medication affects) Medical Complications of Eating Disorders Low blood pressure/pulse, risk of arrhythmias Osteoporosis, fractures Brain volume loss Delayed growth and development Delayed gastric emptying, gastroparesis Muscle wasting Lanugo on body, loss of hair from scalp Decreased body temperature, hypothermia Osteoporosis

8 Brain Volume Loss Medical Complications of Eating Disorders Hypoglycemia Elevated LFT s Low phosphorous Leukopenia, anemia Mitral valve prolapse Secondary amenorrhea Dehydration Electrolyte abnormalities (potassium) Erosion of dental enamel Esophageal tears, rupture Refeeding Syndrome Complication of feeding severely malnourished patients Low phosphorous Seizures Heart failure Arrhythmias

9 Preventing Refeeding Syndrome Close monitoring of electrolytes (particularly phosphorous), cardiac status Start with 1500 kcal diet, gradually increase to 3,000 4,000 Weight regain no more than 2 to 3 pounds per week Avoid use of total parenteral nutrition Inpatient Treatment Necessary for patients with very low weight or medical instability APA guidelines Multidisciplinary approach Child and Adolescent Inpatient Admission Criteria Weight <75% of est. healthy body weight Rapid weight loss even if weight is not less than 75% below the normal weight Refusal to eat Heart rate <50 bpm Blood pressure <80/50 Orthostatic hypotension (with an increase in pulse of 20>bpm or a drop in BP of >10 20 mm Hg/min from supine to standing) Hypokalemia, hypophosphatemia or hypomagnesemia Dehydration Hypothermia Symptomatic hypoglycemia Uncontrolled vomiting or hematemesis Cardiac arrhythmia Syncope Lack of improvement or worsening despite outpatient treatment Suicide intent, plan or high level of risk

10 Adult Inpatient Admission Criteria Weight <75% of estimated healthy body weight (usually BMI <16) Heart rate <40 bpm Symptomatic orthostatic hypotension Blood pressure <90/60 Potassium <3 meq/l Electrolyte imbalance (including hypophosphatemia) Dehydration Hypothermia Symptomatic hypoglycemia Uncontrolled vomiting or hematemesis Cardiac arrhythmia Lack of improvement or worsening despite outpatient treatment Suicide intent and suicide plan or other factors suggesting a high level of suicide risk (which may indicate need for psychiatric hospitalization, but if medically compromised should be admitted to medical unit on 1 to 1 patient monitoring) Treatment of Eating Disorders Psychotherapy Family based therapy Multi-family therapy Cognitive behavioral therapy Interpersonal therapy Cognitive remediation therapy (adjunctive treatment) Medications Inpatient treatment Residential treatment, levels of care Family Based Therapy

11 Family Based Therapy cont. Developed at Maudsley Hospital in London Key interventions Agnostic about etiology, medical model Collaborative weighing Parental and sibling alliances Family meal Phases of treatment Separation of illness from the child Goal to have child eating independently and maintaining an ideal, expected BMI at the 50 th percentile Parents play an active role in helping to restore the child s weight, then transition the control over eating back to the child and encourage normal adolescent development Family Based Therapy cont. Over half of adolescent AN patients are recovered at the end of FBT, with further improvement at later follow up. In older studies, 75 90% are fully weight recovered at 5 year follow-up Currently the first line treatment for Anorexia nervosa in children and adolescents Cognitive Behavioral Therapy Enhanced (CBT-E) for Eating Disorders

12 Key Interventions of CBT-E Collaborative weighing Regular eating Self monitoring Making a cognitive formulation Problem solving and emotion regulation strategies Addressing maintaining factors including interpersonal problems, core low self esteem and clinical perfectionism More involvement of parents in the adolescent protocol CBT-E 20 to 40 weeks of individual therapy Applicable to all types of eating disorders 2/3 of patients with BMI >17.5 recovered at end of treatment, sustained at 1 year follow-up Emerging data for patients with AN Adults and adolescents with 50% recovery at 1 year f/u Studied in adolescents as young as age Interpersonal Therapy Evidence based therapy for Depression in adults and adolescents Effective for Bulimia nervosa Manual exists for Anorexia nervosa Key interventions Interpersonal inventory Problem solving Motivational strategies Formulation Interpersonal World Mood Nutritional Status 12

13 Medications for Bulimia Nervosa Fluoxetine 60 mg/day FDA approved Effective in reducing binge eating and purging Topiramate Odansetron Medications for Anorexia Nervosa SSRI s for comorbid depression or anxiety disorders Olanzapine may be effective in decreasing obsessionality No medications have been shown to improve weight regain What is the role of partial hospital and residential treatment? Practice guidelines 2/3 relapse rate Consideration of comorbid conditions Need for tracking and publishing outcomes
