[Obsessive-compulsive disorders in DSM-5 – what is new?]

Area of Science:

• Psychiatry
• Child and Adolescent Mental Health
• Neurodevelopmental Disorders

Context:

• Obsessive-compulsive disorders (OCDs) are prevalent and impairing conditions in children and adolescents.
• Previous diagnostic systems, like the DSM-IV-TR, categorized OCDs under anxiety disorders.
• The need for updated diagnostic criteria reflecting current research and clinical understanding.

Purpose:

• To critically evaluate the changes in diagnostic criteria for obsessive-compulsive disorders from DSM-IV-TR to DSM-5.
• To highlight the significant reclassification of OCDs into an independent category.
• To discuss the implications of new criteria, including insight assessment and subtypes, for clinical practice and research.

Summary:

• The DSM-5 establishes an independent category for obsessive-compulsive and related disorders, moving them from anxiety disorders.
• Key changes include a broader spectrum of related disorders and a refined emphasis on assessing the patient's level of insight (good, poor, or absent).
• A specific subtype is introduced for obsessive-compulsive disorders associated with tic disorders.

Impact:

• Facilitates more accurate diagnosis and tailored treatment for pediatric obsessive-compulsive disorders.
• Enhances clinical assessment by incorporating insight level as a crucial diagnostic feature.
• Provides a framework for future research into the etiology and treatment of a wider range of obsessive-compulsive and related conditions.
