- Genetic polymorphisms of the 5HT receptors are not related with depression in temporal lobe epilepsy caused by hippocampal sclerosis(2018) VINCENTIIS, Silvia; ALCANTARA, Juliana; RZEZAK, Patricia; KERR, Daniel S.; GATTAZ, Wagner F.; LINDEN JR., Helio van der; SANTOS, Bernardo dos; MELO-SOUZA, Sebastiao E.; ARRUDA, Francisco; RAGAZZO, Paulo; CHAIM-AVANCINI, Tiffany; SERPA, Mauricio H.; FERNANDES, Fernando; MORENO, Ricardo A.; BUSATTO, Geraldo; ALESSI, Ruda; DEMARQUE, Renata; VALENTE, Kette D.Background: Temporal lobe epilepsy caused by hippocampal sclerosis (TLE-HS) is the most frequent form of drug-resistant epilepsy in adults. Mood disorders are the most frequent psychiatric comorbidities observed in these patients. Common pathophysiological mechanisms of epilepsy and psychiatric comorbidities include abnormalities in the serotonin pathway. The primary goal of this study was to determine the possible association between polymorphisms of genes encoding the serotonin receptors 5HT1A (rs6295), 5HT1B (rs6296), and 5HT2C (rs6318) and the presence of mood disorders in patients with TLE-HS. Our secondary goal was to evaluate the possible association between these variants and susceptibility to develop seizures in TLE-HS. Methods: We assessed 119 patients with TLE-HS, with and without psychiatric comorbidities; 146 patients with major depressive disorder; and 113 healthy volunteers. Individuals were genotyped for the rs6295, rs6296, and rs6318 polymorphisms. Results: No difference was observed between the group with TLE-HS, healthy controls, and the group with major depressive disorder without epilepsy regarding the polymorphisms that were evaluated. There was no correlation between rs6318, rs6295, rs6296, and epilepsy-related factors and history of psychiatric comorbidities. Conclusions: Our work suggests that the studied polymorphisms were not related to the presence of TLE, psychiatric comorbidities in TLE, and epilepsy-related factors.
- The relevance of attention deficit hyperactivity disorder in self-limited childhood epilepsy with centrotemporal spikes(2018) LIMA, Ellen Marise; RZEZAK, Patricia; SANTOS, Bernardo dos; GENTIL, Leticia; MONTENEGRO, Maria A.; GUERREIRO, Marilisa M.; VALENTE, Kette D.In this study, we aimed to evaluate the attentional and executive functions in patients with benign childhood epilepsy with centrotemporal spikes (BCECTS) with and without attention-deficit hyperactivity disorder (ADHD) compared with controls and compared with patients with ADHD without epilepsy. We evaluated 12 patients with BCECTS and ADHD (66.7% boys; mean age of 9.67 years); 11 children with non-ADHD BCECTS (63.6% boys; mean age of 11.91 years); 20 healthy children (75% boys; mean age of 10.15 years); and 20 subjects with ADHD without epilepsy (60% boys; mean age of 10.9 years). We used a comprehensive battery of neuropsychological tests to evaluate attentional and executive functions in their broad domains. Patients with BCECTS and ADHD had worse performance in Conners Continuous Performance Test II ( reaction time standard error [p = 0.008], variability [p = 0.033], perseverations [p = 0.044] and in reaction time interstimuli interval [p = 0.016]). Patients with ADHD showed worse performance in Trail Making Test B errors [p = 0.012]. In conclusion, patients with BCECTS and ADHD had worse executive and attentional performance compared with controls than non-ADHD patients with BCECTS. Regardless of the presence of epilepsy, ADHD also negatively impacted executive and attentional functions but in different executive subdomains compared with patients with epilepsy.
- Higher IQ in juvenile myoclonic epilepsy: Dodging cognitive obstacles and ""masking"" impairments(2018) RZEZAK, Patricia; MOSCHETTA, Sylvie Paes; MENDONCA, Melanie; PAIVA, Maria Luisa Maia Nobre; COAN, Ana Carolina; GUERREIRO, Carlos; VALENTE, Kette Dualibi RamosExecutive deficits and impulsiveness are extensively reported in juvenile myoclonic epilepsy (JME). Previous literature suggests that intelligence may mediate these deficits. In this study, we evaluated and compared the performance of adults with JME with high and low intelligence quotient (IQ) and controls on tasks for executive function (EF) and impulsive trails. We investigated the neuropsychological performance of 53 adults with JME and below average IQ (57% women; 26.9 [+/- 7.88] years; mean IQ: 89.8 [+/- 5.1]), 26 adults with JME and average or above average IQ (53.8% women; 28.2 [+/- 9.33] years; mean IQ: 110.7 [+/- 8.3]), 38 controls with below average IQ (55% women; 28.4 [+/- 8.4] years; mean IQ: 90.1 [+/- 5.8]), and 31 controls with average or above average IQ (61.3% women; 32.20 [+/- 11.3] years; mean IQ: 111.6[+/- 10.5]) with a comprehensive battery of neuropsychological tests that measure executive/attentional function. Impulsive traits were assessed using the Cloninger et al.'s Temperament and Character Inventory (novelty seeking (NS) domain). The group with JME with higher IQ presented worse performance compared with controls with higher IQ on Controlled Oral Word Association (COWA) and Wisconsin Card Sorting Test (WCST) (errors). This group showed worse performance than controls with lower IQ on Stroop Color-Word Test (SCT) 1, Trail Making (TM) A, COWA, and WCST (errors). Patients with lower IQ showed worse performance than controls with higher IQ on Digit Span Forward (DSF), Digit Span Backward (DSB), SCT1, SCT2, SCT3, TM A, COWA, and WCST (errors and failure to maintain set). Patients with lower IQ showed worse performance than controls with lower IQ on DSF, DSB, SCTI, SCT2, SCT3, TM A, TM B, COWA, and WCST (errors and failure to maintain set). Patients from groups with low and high IQ showed higher scores than controls with higher and lower IQ on impulsivity for NS1 and NS2 (except for patients with higher IQ versus controls with lower IQ). Adults with JME and higher IQ show less evidence of EF deficits compared with those with JME and below average IQ suggesting that a higher degree of intellectual efficiency may act as a compensatory mechanism. However, it does not minimize some aspects of impulsive traits. Patients with JME and higher cognitive reserve may create strategies to dodge their cognitive obstacles. In this context, intelligence may protect and, at the same time, ""mask"" impairments that could be detected earlier.
