    Abstract:
    In Japan, the impact of DSM-5 has been greater than we had imagined. The Japanese Society of Psychiatry and Neurology organized a group for translation and the members spent many hours in this volunteer effort over a 2-year period. This highlights the significance of and expectations for DSM-5 in clinical practice in Japan. Regarding anxiety disorders, the highlights of changes from DSM-IV-TR to DSM-5 are as follows. Firstly, the DSM-5 chapter on anxiety disorder no longer includes obsessive-compulsive disorder (which is included with obsessive-compulsive and related disorders) or posttraumatic stress disorder and acute stress disorder(which are included with trauma- and stressor-related disorders). However, the sequential order of these chapters in DSM-5 reflects the close relationships among them. Secondly, in DSM-IV, selective mutism and separation anxiety disorder were classified in the section "Disorders Usually First Diagnosed in Infancy, Childhood, or Adolescence." They are now classified as an anxiety disorder. Through these two changes, at the beginning of the chapter, it can be clearly noted that anxiety disorders include disorders that share features of excessive fear and anxiety and related behavioral disturbances. Thirdly, panic disorder and agoraphobia are not associated in DSM-5. Thus, the former DSM-IV diagnoses of panic disorder with agoraphobia, panic disorder without agoraphobia, and agoraphobia without a history of panic disorder are now replaced by two diagnoses, panic disorder and agoraphobia, each with separate criteria. The co-occurrence of panic disorder and agoraphobia is now coded with two diagnoses. This change recognizes that a marked number of individuals with agoraphobia do not experience panic symptoms. For the present, this change ends the. controversy over the hierarchy between panic disorder and agoraphobia. The diagnostic criteria for agoraphobia are derived from the DSM-IV descriptors for agoraphobia, although the clarification of fears from two or more agoraphobia-related situations is now required, because this is a robust means for distinguishing agoraphobia from specific phobias. Also, the criteria for agoraphobia are now extended to be consistent with criteria sets for other anxiety disorders (e.g., a clinician's judgment of the fears as being out of proportion to the actual danger in the situation, with a typical duration of 6 months or more). From the above, these changes from DSM-IV-TR to DSM-5 in anxiety disorders make our judgments faster and more efficient in clinical practice, and DSM-5 is more useful to elucidate the pathology. In this manuscript, we discuss the application and problems based on clinical and research viewpoints regarding anxiety disorders in DSM-5.
