DSM-5 Feeding and Eating Disorders and Somatic Symptom Presentations

Vocabulary practice flashcards covering DSM-5 diagnostic criteria, subtypes, and key clinical terms for Feeding and Eating Disorders as well as Unspecified Somatic Symptom presentations.

Unspecified Somatic Symptom and Related Disorder

A diagnostic category applying to presentations in which symptoms characteristic of a somatic symptom and related disorder cause clinically significant distress or functional impairment predominate but do not meet full criteria for any disorder in the class; used only in decidedly unusual situations where information is insufficient to make a more specific diagnosis.

Pseudocyesis

A false belief of being pregnant that is associated with objective signs and reported symptoms of pregnancy.

Feeding and Eating Disorders

A diagnostic class characterized by a persistent disturbance of eating or eating-related behavior that results in the altered consumption or absorption of food and significantly impairs physical health or psychosocial functioning.

Pica

An eating disorder characterized by the persistent eating of nonnutritive, nonfood substances over a period of at least $1\text{ month}$, which is inappropriate to the developmental level of the individual and not part of a culturally supported or socially normative practice.

Rumination Disorder

A disorder characterized by repeated regurgitation of food over a period of at least $1\text{ month}$, where previously swallowed food is brought up into the mouth without apparent nausea, involuntary retching, or disgust, and may be re-chewed, re-swallowed, or spit out.

Avoidant/Restrictive Food Intake Disorder (ARFID)

An eating or feeding disturbance (manifested by lack of interest in eating, avoidance based on sensory characteristics, or concern about aversive consequences) leading to significant weight loss, nutritional deficiency, dependence on enteral feeding/oral supplements, or marked psychosocial interference, without distortion in body weight or shape perception.

Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS)

A condition characterized by an abrupt, dramatic onset of obsessive-compulsive symptoms or severely restricted food intake, accompanied by a range of additional neuropsychiatric symptoms.

Anorexia Nervosa

A disorder characterized by restriction of energy intake relative to requirements leading to significantly low body weight, an intense fear of gaining weight or persistent behavior interfering with weight gain, and a disturbance in the way body weight or shape is experienced or evaluated.

Anorexia Nervosa, Restricting Type

A subtype of anorexia nervosa in which, during the last $3\text{ months}$, weight loss is accomplished primarily through dieting, fasting, and/or excessive exercise without recurrent episodes of binge eating or purging.

Anorexia Nervosa, Binge-Eating/Purging Type

A subtype of anorexia nervosa in which, during the last $3\text{ months}$, the individual has engaged in recurrent episodes of binge eating or purging behavior (e.g., self-induced vomiting or the misuse of laxatives, diuretics, or enemas).

Binge-Eating Episode

An occurrence characterized by eating, in a discrete period of time (e.g., within any $2\text{-hour}$ period), an amount of food that is definitely larger than what most people would eat under similar circumstances, accompanied by a sense of lack of control over eating.

Bulimia Nervosa

An eating disorder characterized by recurrent episodes of binge eating and recurrent inappropriate compensatory behaviors to prevent weight gain occurring, on average, at least once a week for $3\text{ months}$, with self-evaluation unduly influenced by body shape and weight, in an individual maintaining normal weight or above.

Inappropriate Compensatory Behaviors

Actions used to prevent weight gain following binge eating, including self-induced vomiting, misuse of laxatives, diuretics, or other medications, fasting, or excessive exercise.

Binge-Eating Disorder

A disorder characterized by recurrent episodes of binge eating occurring at least once a week for $3\text{ months}$, associated with marked distress and behavioral indicators (e.g., eating rapidly, uncomfortably full, eating when not hungry, eating alone from embarrassment, feeling disgusted/guilty), in the absence of regular inappropriate compensatory behaviors.

Other Specified Feeding or Eating Disorder (OSFED)

A category applying to presentations causing clinically significant distress or functional impairment that do not meet full criteria for any specific disorder, where the clinician chooses to state the specific reason criteria are not met.

Atypical Anorexia Nervosa

A presentation of Other Specified Feeding or Eating Disorder where all criteria for anorexia nervosa are met, except that despite significant weight loss, the individual's weight remains within or above the normal range.

Purging Disorder

A presentation of Other Specified Feeding or Eating Disorder featuring recurrent purging behavior (e.g., self-induced vomiting, misuse of laxatives or diuretics) to influence weight or shape in the absence of binge eating.

Night Eating Syndrome

A presentation of Other Specified Feeding or Eating Disorder involving recurrent episodes of night eating, manifested by eating after awakening from sleep or excessive food consumption after the evening meal, accompanied by awareness and recall, and causing significant distress or impairment.

Unspecified Feeding or Eating Disorder

A category used when symptoms characteristic of a feeding and eating disorder predominate and cause clinically significant impairment or distress, but the clinician chooses not to specify the reason criteria are not met, or there is insufficient information to make a specific diagnosis.
