The obsessive–compulsive spectrum is a model of medical classification where various psychiatric, neurological and/or medical conditions are described as existing on a spectrum of conditions related to obsessive–compulsive disorder (OCD).[1] "The disorders are thought to lie on a spectrum from impulsive to compulsive where impulsivity is said to persist due to deficits in the ability to inhibit repetitive behavior with known negative consequences, while compulsivity persists as a consequence of deficits in recognizing completion of tasks."[2] OCD is a mental disorder characterized by obsessions and/or compulsions.[3] An obsession is defined as "a recurring thought, image, or urge that the individual cannot control".[4] Compulsion can be described as a "ritualistic behavior that the person feels compelled to perform".[4] The model suggests that many conditions overlap with OCD in symptomatic profile, demographics, family history, neurobiology, comorbidity, clinical course and response to various pharmacotherapies.[1] Conditions described as being on the spectrum are sometimes referred to as obsessive–compulsive spectrum disorders.
