In DSM-II, this category is called Other neurosis
This classification includes specific psychoneurotic disorders not classified elsewhere such as "writer's cramp" and other occasional neuroses. Clinicians should not use this category for patients with "mixed" neuroses, which should be diagnosed according to the predominant symptom.
In DSM-III, this category is called Atypical Anxiety Disorder
This category should be used when the individual appears to have an Anxiety Disorder that does not meet the criteria for any of the specified conditions.
In DSM-IV, this category is called Anxiety Disorder Not Otherwise Specified
This category includes disorders with prominent anxiety or phobic avoidance that do not meet criteria for any specific Anxiety Disorder, Adjustment Disorder With Anxiety, or Adjustment Disorder With Mixed Anxiety and Depressed Mood. Examples include
- Mixed anxiety-depressive disorder: clinically significant symptoms of anxiety and depression, but the criteria are not met for either a specific Mood Disorder or a specific Anxiety Disorder
- Clinically significant social phobic symptoms that are related to the social impact of having a general medical condition or mental disorder (e.g., Parkinson's disease, dermatological conditions, Stuttering, Anorexia Nervosa, Body Dysmorphic Disorder)
- Situations in which the clinician has concluded that an Anxiety Disorder is present but is unable to determine whether it is primary, due to a general medical condition, or substance induced
This category applies to presentations in which symptoms characteristic of an anxiety 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 anxiety disorders diagnostic class. The unspecified anxiety 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 anxiety disorder, and includes presentation in which there is insufficient information to make a more specific diagnosis (e.g., in emergency room settings).
