Abstract

Clinical aspects of obsessive-compulsive disorder and related disorders. Rev Neuropsiquiatr [online]. 2017, vol.80, n.1, pp.35-41. ISSN 0034-8597.  http://dx.doi.org/10.20453/rnp.v80i1.3058.

Obsessive-compulsive disorder (OCD) is a heterogeneous clinical condition that presents a prevalence of 2% and causes great dysfunctionality. Four dimensions have been described for this condition: symmetry/order, contamination/washing, hoarding and sexual/religious/aggression. There is broad comorbidity and evidence of neurobiological differences between anxiety disorders and OCD. DSM-5 and ICD-11 recognize that the core psychopathology of OCD and related disorders is compulsion rather than anxiety. The possibility of adding other clinical specifiers is discussed, and perspectives such as the Research Domain Criteria Project (RDoC), dimensional studies and the integration of diverse research areas open a promising future for these and other psychiatric disorders.

Keywords : obsessive-compulsive disorder; dimensions; obsessions; compulsions; classification; comorbidity.
