Schizophrenia and bipolar disorders are associated with impairment in cognitive functions, and the cognitive profile of these two disorders is similar. However, cognitive defects in these patients may follow different paths. The purpose of the present study was to evaluate and compare the cognitive speed and reaction and decision time in schizophrenia and bipolar patients. For this purpose, in a comparative study, forty patients with schizophrenia, 40 patients with bipolar disorder, and 40 healthy individuals were selected through available sampling, and were tested for positive and negative symptoms of schizophrenia, mania, depression, trial making, reaction time, and general intelligence. The results of Tukey's test showed that cognitive speed and reaction and decision time in bipolar disorder were lower than schizophrenia disorder and healthy individuals, it was also found that the cognitive speed and reaction and decision time in both schizophrenia and bipolar disorders were significantly lower than healthy individuals. This study showed that cognitive functions have been destroyed in schizophrenia and bipolar disorders, and these patients show a lower performance at cognitive speed and reaction and decision time than in healthy individuals. The findings showed that cognitive speed and reaction and decision time in bipolar patients were weaker than schizophrenia disorder. It seems that the study of cognitive functions such as cognitive speed and reaction and decision time in schizophrenia and bipolar patients can help to understand the pathology of these disorders.
