Is executive function distinguishing schizophrenia from bipolar disorder?

ObjectivesThere is an evidence for differential executive function in bipolar type 1 disorder (B1D) and schizophrenia that may tend different cognitive deficits and abnormalities. The objective of this study was to compare the executive function of B1D and schizophrenic patients.MethodWe studied 50 patients with B1D, and 50 schizophrenic participants. All participants completed the Wisconsin Card Sorting Test (WCST) of the Persian version. The participants were match in three basic variables which had most contributions in cognitive conditions in patients. They were Age, educational status and period of illness.ResultsThe two patient groups had compared performance on the WCST. In the WCST, schizophrenic patients showed impairment executive function more than B1D patients.ConclusionsFindings indicated that schizophrenic patients had more dysfunctions executive function than the Bipolar type 1 disorder patients. Although, both disorders may show the impairment in executive function, but the dysfunction in schizophrenia greater than bipolar type 1disorder patients.

AbstractAdults identified as believers and sceptics based on self-reports from a supernatural beliefs scale were assessed on two measures of inhibition; the Stroop Color‐Word Task and the Wisconsin Card Sorting Test (WCST). Both groups were of equal educational status and background. However, believers made significantly more errors than sceptics on all subscales of the WCST but were equivalent in performance on the Stroop measure. This finding is consistent with the idea that supernatural beliefs in adults are related to some types of inhibitory control.

AbstractAlthough several brief sensitive screening tools are available to detect executive dysfunction, few have been developed to quickly assess executive functioning. The INECO Frontal Screening (IFS) is a brief tool which has proved be useful for the assessment of the executive functions in patients with dementia. The aim of this study was to explore whether the IFS is as sensitive and specific as the BADS, a battery designed to assess the dysexecutive syndrome, in schizophrenia. Our sample comprised a group of 34 schizophrenic patients (Mean age = 39.59, DP = 10.697) and 31 healthy controls (Mean age = 35.52, DP = 10.211). To all groups were administered the BADS, Wisconsin Card Sorting Test and IFS. The results suggest that schizophrenic patients performed significantly worse than the control group in all tests (p < .05). The IFS total score was 13.29 for the experimental group and 26.21 for the control group (p < .001). Considering a cut-off of 14 points, the IFS sensitivity was 100% and specificity 56% in detection of executive dysfunction in schizophrenia, compared with the BADS, that if we consider a cut-off of 11 points, was a sensitivity of 100% and a specificity of 50%. Thus, IFS is a brief, sensitive and specific tool for the detection of executive dysfunction in schizophrenia.
