RESUMEN
Background: Obsessive-compulsive disorder (OCD) is a common co-morbid condition in schizophrenia. The clinical implications of this co-morbidity are uncertain. Schizo-obsessive patients were more likely to have paranoid symptoms and first-rank symptoms of schizophrenia. Case description: We present a case of 27 yr old man who initially presented with symptoms suggestive of schizophrenia not responding to treatment and who finally responded to addition of paroxetine to antipsychotics. Discussion: Comorbidity of Schizophrenia and OCD though prevalent is not often diagnosed. . The question of whether or not OCD has a deleterious effect on the outcome of schizophrenia has been often asked but never conclusively answered. Conclusion: The clinical issues in this case study highlights the importance of identification and treatment of OCD in schizophrenia. A detailed history is merited in patients especially those not responding adequately to conventional treatment Key message: Schizo obsessive disorder can be detected and treated early to prevent the development of schizophrenia in future.
