[Classification of obsessivecompulsive disorder: evolution in the DSM-V]

Area of Science:

• Psychiatry
• Mental Health
• Neuroscience

Background:

• Obsessive-compulsive disorder (OCD) was initially classified as an anxiety disorder in the DSM-III.
• The Diagnostic and Statistical Manual of Mental Disorders (DSM) is a key diagnostic tool in psychiatry.

Purpose of the Study:

• To outline the evolution of OCD classification within the DSM system.
• To detail the specific changes in OCD categorization in the DSM-V.
• To highlight the establishment of the
• OCD and related disorders
• category.

Main Methods:

• Comparative analysis of DSM editions (DSM-III vs. DSM-V).
• Review of diagnostic criteria changes for OCD and related conditions.

Main Results:

• DSM-V introduced a new category: "OCD and related disorders."
• Hoarding disorder is now classified separately from OCD.
• Body dysmorphic disorder, trichotillomania, and skin picking disorder are included in this new category.
• DSM-V allows for specifying patient insight and the presence of tics in OCD.

Conclusions:

• The DSM-V represents a significant shift in the conceptualization and classification of OCD.
• This revised classification provides a more nuanced understanding of OCD and its associated conditions.
• The separation of hoarding disorder and inclusion of insight/tic specifiers enhance diagnostic precision.
