Revisiting personality in epilepsy: Differentiation of personality in two epilepsies starting in adolescence.

PURPOSE: The purpose of this study was to investigate personality characteristics and clinical parameters in two well-defined epilepsies: mesial temporal lobe epilepsy related to hippocampal sclerosis (MTLE/HS) and juvenile myoclonic epilepsy (JME) through NEO Revised Personality Inventory (NEO-PI-R) and Neurobehavior Inventory (NBI) standardized instruments. METHODS: One hundred patients undergoing corticoamygdalohippocampectomy (CAH), 100 patients with JME, and 100 control subjects answered the personality measures. Clinical parameters such as psychiatric symptoms, seizure frequency, duration of epilepsy, and side of the lesion in MTLE/HS group were investigated. Statistical analysis consisted of the mean and standard deviation (SD) of each variable. Student's t-test or Fisher exact test were used according to the variable studied. RESULTS: The three groups were within the average range of NEO-PI-R and NBI, although 'tendencies' and differences were demonstrated. The MTLE/HS and control subjects had a similar profile: low scores in Neuroticism and high in Conscientiousness (r = -0.330; p < 0.001/r = -0.567; p < 0.001, respectively) in opposition to what occurred in JME, low in Conscientiousness and high in Neuroticism (r = -0.509; p = 0.005). The NBI 'sense of personal destiny' trait was higher (3.15; p = 0.003) in MTLE/HS than in JME and controls. The JME 'law and order' scores were lower than in other groups (p = 0.024). A tendency towards specific NBI traits differentiates MTLE/HS (Factor 3) from JME (Factor 1) groups. Psychiatric symptoms and seizure frequency were correlated with worse scores in NBI and, especially, in Neuroticism domain of NEO-PI-R. CONCLUSION: Specific personality features were linked to each epileptic disease. These findings highlight the importance of considering unique features linked to epilepsy conditions in daily clinical observation to develop support programmes.

Psychosocial factors associated with in postsurgical prognosis of temporal lobe epilepsy related to hippocampal sclerosis.

We examined the long-term psychosocial trajectory in a consecutive and homogeneous series of 120 patients followed up for five years after corticoamygdalohippocampectomy (CAH). Evaluation of psychosocial variables at baseline and at five-year follow-up were compared. After five years of CAH, a significant improvement in educational level (p=0.004) and employment status (p<0.001) was observed, although retirement (p<0.001) and divorce (p=0.021) rates increased. In a long-term follow-up, a tendency to have similar QOL profile was observed between Engel classes IA and IB (p>0.05). A more favorable surgical outcome (Engel IA) was related to better psychiatric status (p=0.012). Poor psychosocial adjustment before surgery was the most important predictor of QOL outcome (p<0.05). Patients' trajectory after surgical treatment showed positive effects mainly in those with better seizure outcome. Our results emphasized the influence regarding baseline psychosocial functioning on postoperative psychosocial adjustment. Furthermore, many psychosocial gains and difficulties after surgery may be similar in developing and developed countries.

Validity and reliability of the Portuguese-Brazilian version of the Quality of Life in Epilepsy Inventory-89.

OBJECTIVE: The purpose of this article was to report the translation of the Quality of Life in Epilepsy Inventory-89 (QOLIE-89) into a Portuguese-Brazilian version and evaluate its reliability and validity. METHODS: This study involved 105 outpatients: 54 patients with refractory temporal lobe epilepsy (TLE) with mesial temporal sclerosis (MTS) and 51 with juvenile myoclonic epilepsy (JME). Reliability and test-retest reliability were assessed. Relationships between QOLIE-89 domains and other questionnaires (Nottingham Health Profile, Beck Depression Inventory, Adverse Event Profile, Neuropsychological Evaluation), and external measures such as demographic and clinical variables were analyzed to examine construct validity. RESULTS: Internal consistency (Cronbach's alpha=0.73-0.92) and test-retest reliability (intraclass correlation coefficient=0.60-0.84) for individual domains were acceptable. For construct validity, we verified high correlations between the QOLIE-89 and the Nottingham Health Profile, Beck Depression Inventory, Adverse Event Profile, and Neuropsychological Evaluation. For clinical characteristics, the patients with juvenile myoclonic epilepsy had better quality-of-life scores on 11 of 17 QOLIE-89 subscales compared with patients with temporal lobe epilepsy (P<0.05). CONCLUSION: These results support the reliability and validity of the Portuguese-Brazilian translation of QOLIE-89.

Expression of praxis induction on cortical excitability in juvenile myoclonic epilepsy.

OBJECTIVE: This study aimed to evaluate the effects of praxis induction on sensorimotor cortical and transcallosal excitability in juvenile myoclonic epilepsy (JME). METHODS: A total of 36 subjects (18-62years) were included. The JME group was screened by video-electroencephalography neuropsychological protocol and divided into JME without praxis induction [JME-WI (n=12)], JME with praxis-induced seizures or epileptiform discharges [JME-PI (n=10)], and healthy controls (n=14). Motor and somatosensory cortical excitability and transcallosal pathways were evaluated through single-pulse transcranial magnetic stimulation (sTMS) and somatosensory evoked potentials (SEPs). RESULTS: Motor and transcallosal excitabilities tested with sTMS were not different in the motor-dominant or non-dominant hemisphere among groups. Significant differences were found in cortical SEP amplitudes in the P27 component of the non-dominant hemisphere (p=0.03, Cohen's d=0.98), N35 in the dominant hemisphere (p=0.04, Cohen's d=0.96), and P27-35 interpeak amplitude in both somatosensory cortices of the JME-PI group (p=0.03, Cohen's d=0.96; p=0.02, Cohen's d=1.05) when compared with healthy controls. Giant SEPs were observed in two (16.7%) and five (50%) patients of the JME-WI and JME-PI groups, respectively. Cortical latencies did not reveal differences. CONCLUSIONS: Praxis induction was associated with enhanced excitability in the somatosensory cortex of JME patients. SIGNIFICANCE: These findings may help clarifying the less favorable therapeutic response in the JME-PI group and indicate identifying praxis induction as an important determinant in differentiating between JME patients.

Magnetic fields in noninvasive brain stimulation.

The idea that magnetic fields could be used therapeutically arose 2000 years ago. These therapeutic possibilities were expanded after the discovery of electromagnetic induction by the Englishman Michael Faraday and the American Joseph Henry. In 1896, Arsène d'Arsonval reported his experience with noninvasive brain magnetic stimulation to the scientific French community. In the second half of the 20th century, changing magnetic fields emerged as a noninvasive tool to study the nervous system and to modulate neural function. In 1985, Barker, Jalinous, and Freeston presented transcranial magnetic stimulation, a relatively focal and painless technique. Transcranial magnetic stimulation has been proposed as a clinical neurophysiology tool and as a potential adjuvant treatment for psychiatric and neurologic conditions. This article aims to contextualize the progress of use of magnetic fields in the history of neuroscience and medical sciences, until 1985.

Neuropsychological profile of patients with juvenile myoclonic epilepsy: a controlled study of 50 patients.

The purpose of this study was to verify possible cognitive dysfunction in patients with juvenile myoclonic epilepsy (JME) and its relationship to factors related to epilepsy and schooling. Fifty subjects diagnosed with JME and 50 controls underwent neuropsychological assessment evaluating intellectual functions, attention, memory, executive functions, and language. The patients were further divided into two subgroups on the basis of educational level: < or = 11 and >11 years of formal education. Participants diagnosed with JME scored significantly below age-, education-, and gender-matched controls on neuropsychological measures of attention, immediate verbal memory, mental flexibility, control of inhibition, working memory, processing speed, verbal delayed memory, visual delayed memory, naming, and verbal fluency. A positive correlation was observed between duration of epilepsy and cognitive decline. However, in the group of patients with >11 years of education, this correlation was not significant. In this series of patients with JME, neuropsychological evaluation suggests widespread cognitive dysfunction outside the limits of the frontal lobes. The duration of epilepsy correlated with cognitive decline, and patients with higher education manifested less progression of deficits.

IBE Promising Strategies Program 2008: "Epilepsy at School: Teaching the Teachers" - educational plan of the "Associação Brasileira de Epilepsia" with teachers of elementary school / Programa IBE Promising Strategies 2008: "Epilepsia nas Escolas: Ensinando os Professores" - plano educacional da Associação Brasileira de Epilepsia com professores de educação básica

INTRODUCTION: The aim of this study is to evaluate trough questionnaires the knowledge about epilepsy of Elementary School teachers obtained in the "Promising Strategies Program 2008" from International Bureau for Epilepsy entitled "Epilepsy at School. Teaching the Teachers." performed by the official Brazilian branch "Associação Brasileira de Epilepsia" (ABE). METHODS: A questionnaire was developed by ABE and it is composed by 35 objective questions concerning the following areas: concepts and definition of epilepsy and its causes (10); treatment and adverse effects of antiepileptic medication (10); popular stigma about epilepsy (5); activities of people with epilepsy (PWE) (5); and finally, first-aid during and after an epileptic seizure (5). The questionnaire was presented in phase (ph) 1 to teachers before the lecture "Epilepsy: Causes, symptoms and treatment" given by a health professional from ABE trough classical live class (CC) or by video-conference (VC) on "Rede do Saber's site" (http://www.rededosaber.sp.gov.br/portais/NotíciasConteúdo/tabid/369/language/pt-BR/IDNoticia/851/Default.aspx) and afterwards in ph 2. The results were compared to a control group of 66 teachers that did not attend any lecture. RESULTS: Classical class was given in four different cities of Brazil and VC was performed in the state of Sao Paulo and was transmitted to 74 different cities, including Sao Paulo city, this latter with 12 sites; 1,153 teachers were instructed either by CC 25 percent (288) or VC 75 percent (865). Most (78.5 percent) were female, aged between 18 to 68 years (mean 41.4); 76.6 percent attended University and 21.1 percent, graduate studies; 50 percent affirmed to know a PWE. The mean of right answers in ph 1 in CC was 78.4 percent (±10.1) and VC, 79.8 percent (±8.6) and in ph 2 in CC, 86.5 percent (±6.4) and VC, 86.8 percent (±7.1), reflecting increased knowledge in ph 2 (p<0.001) in the 2 strategies (control group: ph 1, 78.2 percent±7.4; ph 2, 79.6 percent±8.6; p>0.05). Comparison of variability of the combined action (CC+VC) between ph 1 (79.5 percent±8.6) and 2 (86.8 percent±6.8) was 9.9 percent±13.9 (p<0.001) (control group 2.3 percent±10.2; p<0.001, compared to CC+VC). The topics "popular stigma" and "first aid during seizures" had the lowest correct scores in ph 1 (CC+VC), 74.6 percent and 72.8 percent, respectively (control group 78.8±10.2 and 67.9±17.5). The highest gain (35.6 percent) in ph 2 was observed in "first aid" (control group 0.8±27.2, p<0.001) and the lowest (0.1 percent), in "popular stigma" (control group 1.7±26.4, p>0.05). There was a significant variation in the topic "first aid" in CC, 41.1 percent compared to VC, 33.3 percent (p=0.009). CONCLUSION: The educational plan of the "Associação Brasileira de Epilepsia" revealed good performance of the teachers of Elementary School without significant differences between the types of presentation (CC/VC), although CC was more efficient to teach first aid during epileptic seizures. The topic "Popular stigma about epilepsy knowledge" has not improved after the lectures and this subject still needs further research and efforts for better understanding and action planning.

OBJETIVOS: Avaliar através de questionários o conhecimento obtido pela ação educativa com professores de Educação Básica intitulada "Epilepsia nas Escolas: Ensinando os Professores" no programa "Promising Strategies 2008" do International Bureau for Epilepsy realizado pelo capítulo oficial brasileiro, a Associação Brasileira de Epilepsia (ABE). MÉTODOS: Questionário foi desenvolvido pela ABE com 35 questões objetivas abrangendo os tópicos: conceitos e definições da epilepsia (10); tratamento e reações adversas de medicações antiepilépticas (10); atividades físicas e profissionais da pessoa com epilepsia (PCE) (5); conhecimento popular estigmatizante (5); cuidados básicos durante e após a crise (5). O questionário foi aplicado antes (Fase 1) e depois (Fase 2) da palestra "Epilepsia: Causas, Sintomas e Conduta" por aula presencial (AP) e videoconferência (VC) na "Rede do Saber" (http://www.rededosaber.sp.gov.br/portais/NotíciasConteúdo/tabid/369/language/pt-BR/IDNoticia/851/Default.aspx). Os resultados foram comparados a um grupo controle de 66 professores que não assistiram à aula sobre epilepsia. RESULTADOS: Aula presencial foi ministrada em quatro cidades brasileiras e VC foi transmitida a 74 cidades do estado de São Paulo, incluindo a capital, esta última com 12 sítios de transmissão. Foram instruídos 1.153 educadores por AP 25 por cento (288) e VC 75 por cento (865). A maioria (78,5 por cento) era do sexo feminino, com idades de 18 a 68 anos (média 41,4); 76,6 por cento cursaram ensino superior e 21,1 por cento, pós-graduação; 50 por cento afirmou conhecer PCE. A média de acertos na fase 1 em AP foi de 78,4 por cento (±10,1) e VC, 79,8 por cento (±8,6) e na fase 2 em AP 86,5 por cento (±6,4) e VC, 86,8 por cento (±7,1), refletindo aumento do conhecimento na fase 2 (p<0,001) nas 2 estratégias (grupo controle: fase 1, 78,2 por cento±7.4; fase 2, 79,6 por cento±8.6; p>0,05). A comparação da variação da ação conjunta (AP+VC) entre fase 1 (79,5 por cento,±8,6) e 2 (86,8 por cento,±6,8) foi de 9,9 por cento±13,9 (p<0,001) (grupo controle 2.3 por cento±10.2; p<0,001, comparado a CC+VC). Os tópicos "conhecimento estigmatizante" e "cuidados básicos" tiveram menor índice de acerto na fase 1 (AP+VC), 74,6 por cento e 72,8 por cento, respectivamente (grupo controle 78,8±10,2 e 67,9±17,5). No entanto, o maior ganho (35,6 por cento) na fase 2 se deu em "cuidados básicos" (grupo controle 0,8±27,2, p<0,001) e o menor (0,1 por cento), em "conhecimento estigmatizante" (grupo controle 1,7±26,4, p>0,05). Houve significante variação do tópico "cuidados básicos" em AP 41,1 por cento comparada à VC 33,3 por cento (p=0,009). CONCLUSÃO: A ação educativa da ABE mostrou bom aproveitamento dos educadores sem diferenças significativas entre os modos de divulgação (AP/VC), porém AP foi mais eficiente em ensinar cuidados básicos na crise epiléptica. O tópico "Conhecimento Popular Estigmatizante sobre Epilepsia" não mostrou aumento após a aula, sendo necessários esforços conjuntos em pesquisa e planejamento estratégico nessa área.
