Obsessive-Compulsive and Related Disorder
Obsessive-Compulsive and Related Disorder (OCRD) is a group of disorders that is characterized by having preoccupations (obsessions) and/or repetitive behaviors (compulsions). Previously, Obsessive-compulsive disorder (OCD) was grouped with the anxiety disorders. However, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) moved OCD into a new category, because much of the evidence suggests OCD and OC-spectrum disorders are distinct from other anxiety disorders. Although OCD and anxiety disorders often share core clinical feature, significant differences also exist in effective first-line pharmacological interventions. Patients with anxiety disorders respond to a wide range of pharmacological interventions. In contrast, patients with OCD do not respond to nonserotonergic agents. OCRD includes OCD, Trichotillomania, Hoarding disorder, Excoriation disorder, and Body dysmorphic disorder.
The usual treatments of OCRD are cognitive behavioural therapy (CBT) and selective serotonin reuptake inhibitors (SSRI).
