Age differences on the California Card Sorting Test: Implications for the assessment of problem solving by the elderly

This study reports the relations among normal aging, intelligence, and frontal lobe functioning. Intelligence tasks and frontal lobe functioning tasks were administered to 107 adults from two age groups (25 to 46 years and 70 to 99 years). Intelligence measures were assessed with two crystallized tests (WAIS Vocabulary and Information subtests), one fluid intelligence test (Cattell's Matrices), and one mixed, crystallized and fluid test (WAIS Similarities subtest). Frontal functioning was assessed using the Wisconsin Card Sorting Test (WCST) and two tests of verbal fluency. Significant age differences in favor of the young were found on the two intelligence tests with a fluid component and on all measures of frontal lobe functioning. Correlational analyses examining the relationship of intelligence measures to frontal variables indicated that these last measures were significantly correlated with only fluid intelligence tests in the elderly group. The implications for the relations among aging, fluid intelligence, and frontal lobe functioning are discussed.

Introduction: This study focuses on the cognitive impairment in patients with bipolar disorder and also the distribution of cognitive flexibility and problem-solving by degree of education, chronicity, and episode of patient is in at the time of evaluation.Methods: This was a cross sectional descriptive study with purposive sampling method. The population was the Harmony in Diversity Group in Surabaya, Indonesia. Twenty-two patients agreed to be subjects and each of them finished the Wisconsin Card Sorting Test (WCST) to measure cognitive flexibility and the Tower of London (TOL) to measure problem-solving. Results: The WCST score are below normal for 90.9% of the patients. Higher cognitive flexibility is found in patients with bachelor’s degree and euthymic patients, while lower cognitive flexibility is found in patients in depression episode, manic episode, and mixed episode. No patients could finish the TOL within the minimum required steps. Better problem-solving is found in patients in manic episode and euthymic patients while lower problem-solving is found in mixed episode and depressive episode.Conclusion: The cognitive flexibility and problem-solving in patients with bipolar disorder are lower than the normal cut off. The type of episode and chronicity are contributing factors. Euthymic patients tend to have better cognitive flexibility and manic patients tend to have better problem-solving ability.

Background:Obesity is a chronic condition associated with poorer cognitive functioning. Wisconsin Card Sorting Test (WCST) is a useful tool for evaluating executive functions. In this study, we assessed the association between dopaminergic gene polymorphisms: DAT1 (SLC6A3), COMTVal158Met, DRD4 (48-bp variable number of tandem repeats - VNTR) and WCST parameters to investigate the functions of the frontal lobes in obese individuals.Objective:To find the significant correlations between polymorphisms of DAT1, COMTVal158Met, DRD4 and executive functions in obese subjects.Methods:The analysis of the frequency of individual alleles was performed in 248 obese patients (179 women, 69 men). Evaluation of the prefrontal cortex function (operating memory and executive functions) was measured with the Wisconsin Card Sorting Test (WCST). Separate analyzes were performed in age subgroups to determine different activities and regulation of genes in younger and older participants.Results:Scores of WCST parameters were different in the subgroups of women and men and in the age subgroups. Regarding the COMT gene, patients with A/A and G/A polymorphisms showed significantly better WCST results in WCST_P, WCST_CC and WCST_1st. Regarding DAT1 men with L/L and L/S made less non-perseverative errors, which was statistically significant. In DRD4, significantly better WCST_1st results were found only in older women with S allele.Conclusion:Obtained results indicate the involvement of dopaminergic transmission in the regulation of prefrontal cortex function. Data analysis indicates that prefrontal cortex function may ensue, from different elements such as genetic factors, metabolic aspects of obesity, and hormonal activity (estrogen).
