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

Classification of obsessive-compulsive disorder : evolution in the DSM V. Obsessive-compulsive disorder (OCD) criteria were first described in the third edition of Diagnostic and statistical manual of mental disorders (DSM), in the 1980's. OCD was then classified as an anxious disorder. Today, a new group in DSM-V included OCD and other closed disorders, called "OCD and related disorders". In this new edition, hoarding, before considered as a symptom of OCD, was isolated in a new disorder called hording disorder. This new family also includes body dysmorphic disorder, trichotillomania and skin picking disorder. Criteria of OCD itself are preserved. In DSM-V it was also added the possibility to specify the degree of insight of the patient, and if tics are or were associated with OCD.
