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 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.


The following conditions have been hypothesized by various researchers as existing on the spectrum.
