- Distinct domains of impulsivity are impaired in juvenile myoclonic epilepsy but not in temporal lobe epilepsy(2015) RZEZAK, Patricia; MOSCHETTA, Sylvie P.; LIMA, Ellen; CASTRO, Carolina X. L.; VINCENTIIS, Silvia; COAN, Ana Carolina; GUERREIRO, Carlos; BUSATTO FILHO, Geraldo; VALENTE, Kette D.Objective: The Barratt Impulsiveness Scale (BIS-11) is the most widely used questionnaire to study impulsivity in persons with psychiatric disorders, but it has rarely been applied to persons with epilepsy. The present study aimed to evaluate the usefulness of BIS-11 as a tool to explore impulsivity in two distinct epilepsy syndromes. Method: The BIS-11 was applied to 20 patients with juvenile myoclonic epilepsy (JME) (32.5 +/- 8.95 years old), 20 patients with temporal lobe epilepsy (TLE) (37.7 +/- 13.25 years old), and 26 healthy controls (31.86 +/- 11.25 years old). The scores in motor, attentional, and lack of planning impulsivity were compared between groups. Results: Patients with JME showed higher scores than patients with TLE and controls in all domains: motor (JME vs TLE: 28.60 vs 13.25 (mean score), p < 0.001 and JME vs controls: 28.60 vs 14.12, p < 0.001), attentional (JME vs TLE: 21.55 vs 13.45, p < 0.001 and JME vs controls: 21.55 vs 14.88, p < 0.001) and nonplanning (JME vs TLE: 28.05 vs 13.10, p < 0.001 and JME vs controls: 28.05 vs 16.15, p < 0.001). Conclusion: Higher BIS-11 scores in all domains of impulsivity [i.e., motor, attentional, and lack of planning] corroborated previous findings described in patients with JME. On the other hand, BIS-11 could not demonstrate problem solving and inhibitory control deficits related to impulsive behavior, which were described in patients with TLE. Other behavioral measures may be more sensitive to some aspects of impulsivity in TLE. Our results reinforce the concept that distinct epileptic syndromes require different neuropsychological approaches, especially considering a complex construct such as impulsivity.
- Social cognition in childhood epilepsy with centrotemporal spikes(2020) LIMA, Ellen Marise; RZEZAK, Patricia; MONTENEGRO, Maria Augusta; GUERREIRO, Marilisa M.; VALENTE, Kette D. R.Purpose: Social cognition is involved in the perception, processing, and interpretation of social information. For this reason, social cognition is a crucial domain for successful communication and interpersonal relationships. With this in mind, we aimed to assess social cognition in children with Self-Limited Childhood Epilepsy with Centrotemporal Spikes (CECTS) and its association with traditional executive function tests and clinical variables of epilepsy. Methods: We evaluated 23 patients with CECTS (65% male, mean age of 10.64 years) and 20 healthy children (75% male, mean age of 10.15 years). We used the Faux-Pas Child Task (FP) to analyze social cognition and a comprehensive battery of neuropsychological tests to evaluate domains of classic executive functions. Results: Patients with CECTS had impairments in FP compared to healthy children [p < 0.001]. Impairments in some areas of traditional executive functions were related to worse social cognition in patients with CECTS. Epilepsy-related factors did not impair the performance on FP, except for the number of antiseizure medication [p = 0.016]. Conclusions: Social cognition is impaired in children and adolescents with CECTS. The presence of ongoing seizures and frequent epileptiform activity were not correlated with social cognition. Therefore, epilepsy per se was more relevant for social cognition than its severity.
- 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.
- Everyday memory impairment in patients with temporal lobe epilepsy caused by hippocampal sclerosis(2017) RZEZAK, Patricia; LIMA, Ellen Marise; GARGARO, Ana Carolina; COIMBRA, Erica; VINCENTIIS, Silvia de; VELASCO, Tonicarlo Rodrigues; LEITE, Joao Pereira; BUSATTO, Geraldo F.; VALENTE, Kette D.Objective: Patients with temporal lobe epilepsy caused by hippocampal sclerosis (TLE-HS) have episodic memory impairment. Memory has rarely been evaluated using an ecologic measure, even though performance on these tests is more related to patients' memory complaints. We aimed to measure everyday memory of patients with TLE-HS to age-and gender-matched controls. Methods: We evaluated 31 patients with TLE-HS and 34 healthy controls, without epilepsy and psychiatric disorders, using the Rivermead Behavioral Memory Test (RBMT), Visual Reproduction (WMS-III) and Logical Memory (WMS-III). We evaluated the impact of clinical variables such as the age of onset, epilepsy duration, AED use, history of status epilepticus, and seizure frequency on everyday memory. Statistical analyses were performed using MANCOVA with years of education as a confounding factor. Results: Patients showed worse performance than controls on traditional memory tests and in the overall score of RBMT. Patients had more difficulties to recall names, a hidden belonging, to deliver a message, object recognition, to remember a story full of details, a previously presented short route, and in time and space orientation. Clinical epilepsy variables were not associated with RBMT performance. Memory span and working memory were correlated with worse performance on RBMT. Significance: Patients with TLE-HS demonstrated deficits in everyday memory functions. A standard neuropsychological battery, designed to assess episodic memory, would not evaluate these impairments. Impairment in recalling names, routes, stories, messages, and space/time disorientation can adversely impact social adaptation, and we must consider these ecologic measures with greater attention in the neuropsychological evaluation of patients with memory complaints.
- Seizure control and anxiety: Which factor plays a major role in social adjustment in patients with Juvenile Myoclonic Epilepsy?(2020) PAIVA, Maria Luisa; LIMA, Ellen Marise; SIQUEIRA, Isabelle Bimbatti; RZEZAK, Patricia; KOIKE, Camila; MOSCHETTA, Sylvie P.; VINCENTIIS, Silvia; ALESSI, Ruda; KHAFIF, Tatiana Cohab; MENDOZA, Melanie; VALENTE, Kette D.Purpose: This study aimed to determine the presence of anxiety disorder and severity of anxiety symptoms in an extensive series of consecutive patients with JME and its association with epilepsy-related factors. In addition, we evaluated the impact of anxiety and clinical variables on social adjustment. Methods: We prospectively evaluated 112 (56.2 % females, mean age 27.2 years) patients with an electroclinical diagnosis of JME and 61 (52.4 % females, mean age 29.3 years) healthy controls. Anxiety symptoms were assessed by the State and Trait Anxiety Inventory (STAI). Social functioning was addressed with Self-Report Social Adjustment Scale (SAS). The patient group was also evaluated with a psychiatric interview. Results: Patients with JME presented more severe anxiety symptoms and worse social adjustment compared with controls. The presence of anxiety disorder and the severity of anxiety symptoms was associated with frequent seizures - generalized tonic-clonic seizures (p= 0.008) and drug-resistant epilepsy (p= 0.021). Regarding social adjustment, the severity of anxiety symptoms was associated with lower economic adjustment (p= 0.039), while the presence of anxiety disorder impacted family relationships (p 0.025). The presence of hard-to-control myoclonic seizure was associated with lower scores on work (p= 0.019), leisure activities (p= 0.008), family relationship (p= 0.022) and overall social adjustment (p= 0.038). Conclusion: Patients with JME have severe anxiety symptoms and worse social adjustment. Anxiety disorder and symptoms were associated with frequent seizures and drug-resistant epilepsy. Epilepsy-related factors and anxiety impaired distinct aspects of social functioning.
- The executive profile of children with Benign Epilepsy of Childhood with Centrotemporal Spikes and Temporal Lobe Epilepsy(2017) LIMA, Ellen M.; RZEZAK, Patricia; GUIMARAES, Catarina A.; MONTENEGRO, Maria A.; GUERREIRO, Marilisa M.; VALENTE, Kette D.Rationale: Benign Epilepsy of Childhood with Centrotemporal Spikes (BECTS) and temporal lobe epilepsy (TLE) represent two distinct models of focal epilepsy of childhood. In both, there is evidence of executive dysfunction. The purpose of the present study was to identify particular deficits in the executive function that would distinguish children with BECTS from children with TLE. Methods: We prospectively evaluated 19 consecutive children and adolescents with TLE with hippocampal sclerosis (HS) (57.9% male; mean 11.74 years [SD 2.05]; mean IQ 95.21 [SD 15.09]), 19with BECTS (36.8% male; mean 10.95 years [SD 2.33]; mean IQ 107.40 [SD 16.01]), and 21 age and gender-matched controls (33.3% male; mean 11.86 years [SD 2.25]; mean IQ 108.67 [15.05]). All participants underwent a neuropsychological assessment with a comprehensive battery for executive and attentional functions. We used ANOVA and chi-square to evaluate differences on demographic aspects among groups (BECTS, TLE-HS, and control groups). Group comparisons on continuous variables were complemented by MANOVA and Bonferroni posthoc comparisons. Results: Patients with BECTS had worse performance than controls in: Matching Familiar Figures Test, time (p = 0.001); Matching Familiar Figures Test, time x errors index (p < 0.001); Verbal Fluency for foods (p = 0.038); Trail Making Test, part B time (p = 0.030); Trail Making Test, part B number of errors (p = 0.030); and WCST, number of categories achieved (p = 0.043). Patients with BECTS had worse performance than patients with TLE-HS on Matching Familiar Figures Test, time (p = 0.004), and Matching Familiar Figures Test, time x errors index (p < 0.001). Patients with TLE-HS had worse performance than controls on the following tests: Verbal Fluency for foods (p = 0.004); Wisconsin Card Sorting Test, the number of categories achieved (p < 0.001); and Wisconsin Card Sorting Test, the number of perseverative errors (p = 0.028). Patients with TLE-HS had worse performance than patients with BECTS on Digit Backward (p = 0.002); and the Wisconsin Card Sorting Test, the number of perseverative errors (p < 0.001). Conclusions: Patients with TLE and BECTS present distinct cognitive profiles. Patients with TLE-HS had worse performance in mental flexibility, concept formation, and working memory compared to BECTS. Patients with BECTS had worse inhibitory control compared to children with TLE-HS. Both TLE-HS and BECTS had a higher number of errors on an inhibitory control test. However, patients with BECTS had a slower mental processing even when compared to patients with TLE-HS. Rehabilitation programs for children with epilepsy must include children with benign epilepsies and must take into account the epileptic syndrome and its particular neurocognitive phenotype.
- Dissociation between decision making under ambiguity and risk in patients with juvenile myoclonic epilepsy(2019) PAIVA, Maria L.; RZEZAK, Patricia; SANTOS, Bernardo; LIMA, Ellen M.; MOSCHETTA, Sylvie P.; VINCENTIIS, Silvia; ALESSI, Ruda; MENDOZA, Melanie; VALENTE, Kette D.Introduction: Decision making (DM) is one aspect of impulsivity that can be defined by the ability to decide between two or more options in a given situation. To date, there are at least two types of DM that differ in the level of uncertainty, and how much information about consequences is provided. In this study, we aimed to evaluate the two domains of DM - under risk and ambiguous - with a comprehensive evaluation in a group of patients with juvenile myoclonic epilepsy (JME), and correlate with patients' characteristics, clinical variables, and neuropsychological evaluation for executive functions. Methods: We evaluated 35 patients with JME and 39 healthy controls using the Iowa Gambling Task for DM under ambiguity and the Game Dice Task for DM under risk. We assessed the performance in Iowa Gambling Task and Game Dice Task through net scores, safe and risky choices, besides the type of decisions across time. Results: Patients with JME had a higher number of risky choices compared to controls in the Game Dice Task. There was no significant difference between patients and controls in the Iowa Gambling Task. However, patients with higher seizure frequency had worse scores on decks C and D (safe choices) from the Iowa Gambling Task. Conclusion: Patients with JME have worse performance on DM under risk. The same was not observed for DM under ambiguity. Epilepsy-related factors and the presence of psychiatric disorders, but not executive dysfunction, were associated with a lower tendency for safe choices. These findings showed a dissociation between DM processes in patients with JME and a tendency to make disadvantageous decisions with measurable risks.
- Decision-making in patients with temporal lobe epilepsy: Delay gratification ability is not impaired in patients with hippocampal sclerosis(2016) RZEZAK, Patricia; LIMA, Ellen Marise; PEREIRA, Fabricio; GARGARO, Ana Carolina; COIMBRA, Erica; VINCENTIIS, Silvia de; VELASCO, Tonicarlo Rodrigues; LEITE, Joao Pereira; BUSATTO, Geraldo F.; VALENTE, Kette D.Background: Decision-making abilities have rarely been examined in patients with temporal lobe epilepsy related to hippocampal sclerosis (TLE-HS). We aimed to investigate the ability to delay gratification, a decision-making subdomain, in patients with intractable TLE-HS and to verify the association of delay gratification performance and cool executive function tests. Methods: We evaluated 27 patients with TLE-HS (mean age: 35.46 [+/- 13.31] years; 7 males) and their cognitive performance was compared with that of 27 age- and gender-matched healthy controls (mean age: 35.33 [+/- 12.05] years; 7 males), without epilepsy and psychiatric disorders. Patients were assessed using the delay discounting task (DDT) and tests of attention, shifting, inhibitory control, and concept formation. Results were correlated with clinical epilepsy variables such as age of onset, epilepsy duration, AED use, history of status epilepticus, febrile seizures, and the presence of generalized seizures. Statistical analysis was performed using one-way ANCOVA with years of education as a confounding factor. Results: Patients and controls demonstrated similar performance on DDT, showing similar discount rate (p = 0.935) and probability rate (p = 0.585). Delay gratification was not related to cool executive function tests (Digit Span, Stroop Color Test, Trail Making Test, Wisconsin Card Sorting Test, and Connors' CPT). History of status epilepticus, presence of generalized seizures and higher seizure frequency, age at onset, and epilepsy duration had a significant impact on DDT. Conclusion: Patients with intractable TLE-HS showed unimpaired delay gratification abilities, being able to accept a higher delay and a lower amount of chance for receiving a higher reward in the future. Clinical variables related to the epilepsy severity impacted the performance on delay gratification. Impairment on cool aspects of executive function was unrelated to this decision-making domain.
