- 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.
- Quality of life and psychosocial adjustment: the moderator role of anxiety symptoms in persons with temporal lobe epilepsy due to hippocampal sclerosis(2023) LIMA, E. M.; GOIS, J.; VINCENTIIS, S.; VALENTE, K. D. R.
- 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.
conferenceObject Impact of cognitive rehabilitation in juvenile myoclonic epilepsy: A novel study(2021) PAIVA, Maria Luisa; SERAFIM, Antonio de Padua; ALESSI, Ruda; VINCENTIIS, Silvia; LIMA, Ellen; NADRUZ, Patricia; VALENTE, KetteconferenceObject Polytherapy, frequent seizures, and bilateral tonic-clonic seizures influence on higher depressive and anxiety symptoms in temporal lobe epilepsy(2021) LIMA, Ellen Marise; GOIS, Juliana; PAIVA, Maria Luisa; VINCENTIIS, Silvia; MOSCHETTA, Sylvie; VALENTE, Kette- 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.
- Factors associated with caregiver burden of adults with epilepsy in a middle-income country(2022) OLIVEIRA, Mariana C.; LIMA, Ellen Marise; PAIVA, Maria Luisa Nobre de; VALENTE, Kette Dualibi RamosPurpose: Despite the relevance of socio-economic background in burden of caregivers of persons with epilepsy (PWE), there is a dearth of knowledge about this topic in low-resource settings. Here we attempt to identify the extent of the burden in caregivers of adults with epilepsy in a middle-income country and the factors associated with it. Methods: In this cross-sectional study, we evaluated the level of burden with the Zarit Caregiver Burden Inventory. A comprehensive questionnaire was developed to assess the demographics of patients and caregivers. Epilepsy-related factors were obtained by interview and file review. Depressive, anxiety symptoms, and sleep quality were evaluated by Beck Depression Inventory, State and Trait Anxiety Inventory, and Pittsburgh Sleep Quality Index. Stigma was evaluated by the Stigma Scale of Epilepsy. Results: The caregiver's burden was mild to moderate in our sample. The factors most strongly associated with the higher caregiver burden were age-onset of epilepsy, PWE years of schooling, needs for assistance in daily life, disabilities, and caregiver's bad-quality of sleep and higher depressive and anxiety symptoms. Conclusion: Caregivers of PWE deserve special attention regarding mental health and other health aspects, such as sleep quality.
- 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.
- Sleep quality and circadian rhythm profile of persons with juvenile myoclonic epilepsy in a tertiary epilepsy center: A case-control study(2023) KOIKE, Camila; LIMA, Ellen M.; PAIVA, Maria L.; PENTAGNA, Alvaro; BIMBATTI, Isabelle; VALENTE, Kette D.Purpose: This study evaluated sleep quality, chronotype, and excessive diurnal somnolence in persons with Ju-venile Myoclonic Epilepsy (JME) and their possible association with clinical variables. Methods: This cross-sectional controlled study evaluated 49 consecutive patients (65% females, mean age 27.53 years) with an electroclinical diagnosis of JME and 49 healthy controls (55% females, mean age 28.55 years). The Pittsburgh Sleep Quality Inventory (PSQI) was used to assess sleep quality and the Epworth Sleepiness Scale (ESS) to evaluate excessive daytime sleepiness. The patients' chronotype was evaluated by the Morningness-Eveningness Questionnaire (MEQ). Epilepsy-related factors gathered from the medical chart and personal interview were epilepsy duration, age at onset, frequency of myoclonic (Mcl), generalized tonic-clonic (GTC) and absence (ABS) seizures, pharmacoresponse, and current antiseizure medication (ASM).Results: Persons with JME did not differ from the control group regarding daytime sleepiness (p=0.840); how-ever, the JME group had worse sleep quality (p=0.01) than the controls. Persons with JME presented a more evening chronotype than controls (p = 0.003). The age at onset, epilepsy duration, frequency of Mcl seizure, frequency of GTC seizure, frequency of ABS seizure, and drug response did not predict ESS and MEQ scales. Pharmacoresponsive patients had lower PSQI scores compared with pharmacoresistant patients (p=0.036). Conclusion: Persons with JME have worse sleep quality and a more evening chronotype. Notably, pharmacor-esistant patients present a worse sleep quality that deserves attention and special care due to the relationship between sleep deprivation and seizure worsening.
