Results In patients with the number of the number of patients with bipolar disorder group was significantly better than the bipolar disorder group (t=2.54, P=0.014). () and total number (t=-2.01, P=0.05) were significantly higher in the number of patients with bipolar disorder than in schizophrenia group in the digit span (t=-2.11, P=0.04). Patients with male patients in the rehabilitation phase of bipolar disorder group in the connection test B spent less time than men in the schizophrenic group (t=1.81, P=0.06).
