Diagnosis and treatment of a patient with both psychotic and obsessive-compulsive symptoms

Carolyn I Rodriguez et al. Am J Psychiatry. 2010 Jul.

Abstract

When a patient presents with both psychotic and obsessive-compulsive symptoms, the clinician is faced with a differential diagnosis that includes comorbid schizophrenia and obsessive-compulsive disorder (OCD), OCD with poor insight, and schizophrenia with antipsychotic-induced obsessive-compulsive symptoms. If the psychotic symptoms are subthresh-old or attenuated in form, the individual may have OCD and putative prodromal schizophrenia. The authors present a case to outline a strategy for differentiating among these possible diagnoses and for optimizing treatment.
