ABSTRACT
Diagnostic reductionism, the tendency to attribute all of the symptoms and signs shown by those with schizophrenia to the schizophrenia alone, contributes to the widespread tendency to treat schizophrenia as if it were a single, unitary disorder (Bermanzohn et al. 2000, 2001). This tendency toward reductionism is greatly reinforced by hierarchical conceptions of diagnosis embedded in the DSM system (ibid.), which are still present in DSM-IV (APA 1994). The reductionist frame of mind causes psychiatry to neglect commonly occurring problems among schizophrenic patients.1 This chapter will address depression, obsessive-compulsive disorder (OCD), and panic disorder. These three disorders are commonly found in schizophrenia and are often ignored or neglected.
