The Psychopathology of schizophrenia is composed of many heterogeneous symptom complex, and multifaceted approaches have been done on this subject. It is so simplified a method that the complex symptoms of schizophrenia are classified into only positive and negative symptoms. Preceded studies of other researchers said cognitive deficit of the schizophrenics played important roles in the symptom formation. The purpose of this study is the evaluation of the relationship between the symptoms of schizophrenia and the memory function and low level of cognitive function. In this study, 30 subacute and chronic schizophrenic patients were included. PANSS(Positive and Negative Symptom Scale) was applied to evaluate the clinical symptoms in each subject. The memory function and low level cognitive function were evaluated using WMS-R(Wechsler Memory Scale-revised version) and Decision-reaction timer. The results showed negative correlations between cognitive factor of PANSS(5 factor model) and delayed recall of WMS-R. These results suggest the possibility that symptom evaluation using PANSS can be a preliminary estimation of cognitive function in schizophrenia.
