In DSM-III, this category is called Atypical Impulse Control Disorder
This category is for Disorders of Impulse Control that cannot be classified elsewhere.
In DSM-IV, this category is called Impulse-Control Disorder Not Otherwise Specified
This category is for disorders of impulse control that do not meet the criteria for any specific Impulse-Control Disorder or for another mental disorder having features involving impulse control described elsewhere in the manual (e.g., Substance Dependence, a Paraphilia).
This category applies to presentations in which symptoms characteristic of a disruptive, impulse-control, and conduct disorder that cause clinically significant distress or impairment in social, occupational, or other important areas of functioning predominate but do not meet the full criteria for any of the disorders in the disruptive, impulse-control, and conduct disorders diagnostic class. The unspecified disruptive, impulse-control, and conduct disorder category is used in situations in which the clinician chooses not to specify the reason the criteria are not met for a specific disruptive, impulse-control, and conduct disorder, and includes presentations in which there is insufficient information to make a more specific diagnosis (e.g., in emergency room settings).
