Memory Performance of the Patients with Schizophrenia and Bipolar Disorder

This study was to investigate the memory performance and affective memory of the patients with schizophrenia and bipolar disorder. The subjects consisted of 3 groups-16 schizophrenics, 16 bipolar disorder patients and 16 normal controls. Memory performance test was conducted to each group after they were matched according to age, sex, scaled score of information of Korean Wechsler Intelligence scale, duration of total admission, frequency of hospitalization, duration of illness and daily dose of antipsychotics. And then, analyses were done by scores of recall task and recognition task, scores of memory clustering of recall task and memory strategies. The results were as follows : 1) For the total and pleasnt word recall, the schizophrenics and bipolar disorder patients showed significantly low scores than normal controls(p<.Ol). But there was no significant difference between schizophrenic group and bipolar disorder group. 2) For the memory clustering of the recall task, the schizophrenics and bipolar disorder patients showed significantly low scores on memory clustering than normal controls(p<C.Ol). But there was no significant difference between schizophrenic group and bipolar disorder group. 3) For the total and pleasant word recognition, the schizophrencs showed significantly low scores than normal controls(p<.05), but there was no significant difference between bipolar disorder group and normal controls. And also, there was no significant difference between schizophrenic group and bipolar disorder group. 4) Memory deficits in schizophrenics were due to the problem in memory strategies.
