[Schizophrenia and obsessive-compulsive disorder--some considerations based on a case].

The authors report the case of a male patient whose illness started with obsessive-compulsive symptoms and later developed into undifferentiated type schizophrenia. They explore the changes in the symptomatology of the young male and the treatment interventions used. The authors emphasize the common appearance of obsessive-compulsive symptoms with schizophrenia and present data on the epidemiology and psychopathology of the recently published schizo-obsessive subtype of schizophrenia. They point at the importance of early detection and complex treatment approaches.
