AbstractThe relationship between attention deficit/hyperactivity disorder (ADHD) and frontal lobe epilepsy (FLE) in children is not well understood. Patients with FLE between 6 and 15 years of age were studied. Scores on the ADHD rating scale (ADHD-RS) and Wisconsin card sorting test (WCST) were obtained at baseline. Behavioral changes were evaluated using the ADHD-RS scores at 6, 12, and 24 months after seizure onset. Perseverative errors of Nelson (PEN) scales on WCST were also evaluated at same time periods. The relationships between clinical manifestations and neuropsychological disturbances were analyzed. In 34 patients, the ADHD-RS score at 24 months after onset was most strongly associated with the presence of status epilepticus (SE, p = 0.004, β = 0.490) followed by seizure frequency (p = 0.021, β = 0.382). The increase in ADHD-RS score was most strongly associated with seizure frequency (p < 0.001, β = 0.635). The PEN score on WCST at 24 months was most strongly associated with seizure frequency (p = 0.001, β = 0.724). The increase in PEN score on WCST was most strongly associated with seizure frequency (p = 0.001, β = 0.872). The only clinical factor associated with both the ADHD-RS and the PEN scores on the WCST was seizure frequency. Seizure frequency may be correlated with risk for ADHD in children with FLE.

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).
