Methods: A descriptive, cross-sectional study. The assessment using the WCST (Wisconsin Card Sorting Test) included sixteen patients with a clinical diagnosis of CVA and frontal lobe impairment. Results from the two groups were compared (patients with right frontal lobe impairment and patients with left frontal lobe impairment). Statistical analysis was performed using the program “Statistical Package for Social Sciences” (SPSS) Version 20.0. For comparison between groups was used Mann-Whitney test and considered the alpha level of 0.05 on the statistically significant results. Results: There was no statistically significant difference between the groups, thus showing that executive functions are symmetrically distributed across the frontal lobes. Conclusion: Executive functions are symmetrically organized across the two frontal lobes, since the comparison between the groups did not demonstrate a statistically significant difference for any of the variables of WSCT.展开更多

METHODS The frontal assessment battery(FAB) was applied to 87 patients with liver cirrhosis(16 with and 71 without OHE) and 40 control subjects without cirrhosis treated at the alcohol and liver outpatient clinics and the gastroenterology ward of the Cassiano Ant?nio de Moraes University Hospital(Hospital Universitário Cassiano Ant?nio de Moraes- HUCAM), Espírito Santo, Brazil.RESULTS The average FAB score was lower for the cirrhotic than for the non-cirrhotic patients(10.6 ± 3.67 vs 12.25 ± 2.72, P = 0.015). The FAB score was lower for the cirrhotic patients with OHE than for the patients without OHE(8.25 ± 4.55 vs 11.14 ± 3.25, P = 0.027). The total FAB score was lower for the cirrhotic patients without OHE than for the non-cirrhotic patients, although this difference was not significant(11.14 ± 3.25 vs 12.25 ± 2.72, P = 0.067). Nevertheless, the difference in the scores on the subtest that assessed the ability to inhibit a response previously conditioned to a stimulus was significant(1.72 ± 0.93 vs 2.2 ± 0.85, P = 0.011).CONCLUSION The present study indicates that the FAB is a promising tool for outpatient minimal HE screening and the assessment of HE severity.展开更多
