Review[Obsessive-compulsive disorder and schizophrenia. A critical review].
Co-occurrence of psychotic and obsessive-compulsive symptoms has been recognized for decades. This paper reviews published reports from five perspectives: schizophrenia with obsessive-compulsive symptoms, obsessive-compulsive disorder (OCD) with psychotic symptoms, schizophrenia-spectrum-personality disorder with obsessive-compulsive symptoms, obsessive-compulsive symptoms induced by atypical antipsychotics and similarities of functional neural circuits theory in OCD and schizophrenia. A MEDLINE search was conducted to identify relevant articles from 1960 until 2004. ⋯ Exploring the interface of schizophrenic and obsessive-compulsive symptoms is important for diagnostic clarity and could have important implications for treatment and long-term prognosis. The review emphasizes the different origins and natural course of co-occurrence of schizophrenic and obsessive-compulsive symptoms and their various outcome under atypical antipsychotics and selective serotonin reuptake inhibitors (SSRI). Further double-blind, randomized, placebo-controlled investigations in larger cohorts of schizophrenic and OCD patients are needed in order to identify a schizo-obsessive schizophrenia and a schizotypal subtype of obsessive compulsive disorder and to substantiate the algorithm for treatment.
