3. BInge—eating disorder (of low frequency andlor limited duration): All of the criteria for binge-eating disorder are met, except that the binge eating occurs, on average, less than once a week and/or for less than 3 months.
4. Purging disorder: Recurrent purging behavior to influence weight or shape (e.g., selt- induced vomiting; misuse of laxatives, diuretics, or other medications) in the absence of binge eating.
5. Night eating syndrome: Recurrent episodes of night eating, as manifested by eating after awakening from sleep or by excessive food consumption after the evening meal.
There is awareness and recall of the eating. The night eating is not better explained by external influences such as changes in the individual’s sleep-wake cycle or by local so- cial norms. The night eating causes significant distress andlor impairment in function- ing. The disordered pattern of eating is not better explained by binge-eating disorder or another mental disorder, including substance use, and is not attributable to another medical disorder or to an effect of medication.
307.50 (F50.9)
This category applies to presentations in which symptoms characteristic of a feeding and eating disorder that cause clinically significant distress or impairment in social, occupation- al, or other important areas of functioning predominate but do not meet the full criteria for any of the disorders in the feeding and eating disorders diagnostic class. The unspecified feeding and eating disorder category is used in situations in which the clinician chooses not to specify the reason that the criteria are not met for a specific feeding and eating dis- order, and includes presentations in which there is insufficient information to make a more specific diagnosis (e.g., in emergency room settings).
Elimination disorders all involve the inappropriate elimination of urine or feces and are usually first diagnosed in childhood or adolescence. This group of disorders in- cludes enuresis, the repeated voiding of urine into inappropriate places, and encopresis, the repeated passage of feces into inappropriate places. Subtypes are provided to differentiate nocturnal from diurnal (i.e., during waking hours) voiding for enuresis and the presence or absence of constipation and overﬂow incontinence for encopresis. Although there are min- imum age requirements for diagnosis of both disorders, these are based on developmental age and not solely on chronological age. Both disorders may be voluntary or involuntary.
Although these disorders typically occur separately, co-occurrence may also be observed.
Diagnostic Criteria 307.6 (F98.0)
A. Repeated voiding of urine into bed or clothes, whether involuntary or intentional.
B. The behavior is clinically significant as manifested by either a frequency of at least twice a week for at least 3 consecutive months or the presence of clinically significant distress or impairment in social, academic (occupational), or other important areas of functioning.
C. Chronological age is at least 5 years (or equivalent developmental level).
D. The behavior is not attributable to the physiological effects of a substance (e.g., a di- uretic, an antipsychotic medication) or another medical condition (e.g., diabetes, spina bifida, a seizure disorder).
Specify whether:
Nocturnal only: Passage of urine only during nighttime sleep.
Diurnal only: Passage of urine during waking hours.
Nocturnal and diurnal: A combination of the two subtypes above.
