Abstract

Much converging evidence suggests that a specific role is played by the dorsolateral prefrontal cortex (DLPC) in schizophrenic disorders and by the orbitofrontal cortex (OFC) in obsessive-compulsive disorder (OCD). In this study, 25 schizophrenic and 25 OCD patients were evaluated with the Wisconsin Card Sorting Test and the Object Alternation Test, tests that are sensitive to DLPC and OFC damage, respectively. The patients were also given the Weigl Sorting Test and Word Fluency Test to assess global frontal functioning. The results point to a DLPC deficit in schizophrenia and an OFC lability in OCD and confirm that functional disorders of the central nervous system can be investigated using neuropsychological methods.
