OSDD-2 stands for Other Specified Dissociative Disorder, Type 2. It is a subcategory of dissociative disorders and was included in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition). However, it's important to note that the DSM-5 has been subject to updates and revisions, so it is always essential to refer to the latest version or subsequent updates for the most accurate information.
OSDD-2 was a diagnostic category that aimed to capture cases of dissociative disorders that didn't fully meet the criteria for Dissociative Identity Disorder (DID) or Dissociative Disorder Not Otherwise Specified (DDNOS, now called Other Specified Dissociative Disorder, Type 1).
In the DSM-5, OSDD-2 was described as a condition where there were recurrent episodes of identity disruption or fragmentation but without the presence of fully formed, distinct identities that are seen in DID. It differed from OSDD-1 (DDNOS, Type 1) in that it specifically excluded cases where there was amnesia between the episodes of identity disruption.
Since the release of the DSM-5, there have been discussions about the usefulness and clarity of the OSDD-2 category. Some mental health professionals argued that the distinctions between OSDD-2 and other dissociative disorders were not well-defined, leading to potential overlap or confusion in diagnoses.
As a result, the DSM-5 was followed by the DSM-5-TR (Text Revision), and then later by the DSM-5-2 (Second Edition). However, the DSM-5-2 had not been released yet, so it's possible that there have been further changes or updates to the diagnostic criteria for dissociative disorders since then.
If you or someone you know is experiencing symptoms related to dissociation or identity disruption, it is important to seek professional help from a qualified mental health provider who can conduct a thorough assessment and provide an accurate diagnosis based on the most current diagnostic criteria.
