Obsessive-compulsive disorder (OCD) with psychotic symptoms and response to treatment with SSRI -: A case report

The co-occurrence of obsessive-compulsive and psychotic symptoms in one patient often represents a diagnostic problem. Distinguishing among a schizophrenic disorder with comorbid obsessional symptoms, an OCD with comorbid psychotic symptoms, or an OCD and schizophrenia or any other psychotic disorder is of clinical importance, since the different diagnoses have different therapeutic as well as prognostic implications. In the following case report we describe a patient who suffered from a typical OCD for more than 18 years and then developed clear psychotic symptoms that completely remitted after treatment with citalopram.
