The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), which is the most recent version of the manual, was published in 2013 and introduced several new diagnostic categories and changes from the previous version, DSM-IV-TR.
Some of the significant changes and additions in DSM-5 include:
- Autism Spectrum Disorder (ASD) – This category combines four previously distinct diagnoses (autistic disorder, Asperger’s disorder, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified) into a single diagnostic category.
- Disruptive Mood Dysregulation Disorder – This new disorder was added to describe severe and recurrent temper outbursts that are inconsistent with developmental level and occur frequently.
- Binge Eating Disorder – This disorder was elevated from a provisional diagnosis in DSM-IV-TR to a full diagnostic category in DSM-5, reflecting the growing recognition of its clinical significance.
- Obsessive-Compulsive and Related Disorders – This new category includes disorders that were previously classified under anxiety disorders in DSM-IV-TR, such as hoarding disorder, trichotillomania (hair-pulling disorder), and excoriation (skin-picking) disorder.
- Cultural Formulation Interview – This new section in DSM-5 provides a structured way for clinicians to consider cultural factors that may impact diagnosis and treatment of mental health disorders.
It’s worth noting that the DSM-5 represents a significant departure from previous versions of the manual, particularly in its approach to diagnostic categories and its emphasis on dimensional assessment rather than categorical diagnosis.
