Despite the growing evidence of poor psychosocial adjustment, at present there is no formal method of assessment of social adjustment in patients with temporal lobe epilepsy (TLE). First, we assessed social adjustment in patients with TLE using a self-report questionnaire and compared the results with those from quality-of-life (QOL) scales. Second, we verified the influence of cognitive performance and clinical variables of epilepsy on social adjustment and QOL We evaluated 35 people with TLE and 38 healthy controls. Patients had worse social adjustment, and it was correlated with worse perception of cognitive function. Attention and verbal memory dysfunctions were negatively correlated with social adjustment. However, there was no significant correlation between cognitive performance and QOL Regarding clinical variables, persons with left TLE showed worse social adjustment and patients with frequent seizures showed worse QOL These findings indicate the relevance of evaluating social adjustment and emphasize the importance of cognitive rehabilitation to improved social adjustment.

An association between memory and executive dysfunction (ED) has been demonstrated in patients with mixed neurological disorders. We aimed to investigate the impact of ED in memory tasks of children with temporal lobe epilepsy (TLE). We evaluated 36 children with TLE and 28 controls with tests for memory, learning, attention, mental flexibility, and mental tracking. Data analysis was composed of comparison between patients and controls in memory and executive function; correlation between memory and executive function tests; and comparison between patients with mild and severe ED in memory tests. Children with TLE had worse performance in focused attention, immediate and delayed recall, phonological memory, mental tracking, planning, and abstraction. Planning, abstraction, and mental tracking were correlated with visual and verbal memory. Children with severe ED had worse performance in verbal and visual memory and learning tests. This study showed that ED was related to memory performance in children with TLE. (C) 2012 Elsevier Inc.

Pathology studies in epilepsy patients bring useful information for comprehending the physiopathology of various forms of epilepsy, as well as aspects related to response to treatment and long-term prognosis. These studies are usually restricted to surgical specimens obtained from patients with refractory focal epilepsies. Therefore, most of them pertain to temporal lobe epilepsy (TLE) with mesial temporal sclerosis (MTS) and malformations of cortical development (MCD), thus providing information of a selected group of patients and restricted regions of the brain. Postmortem whole brain studies are rarely performed in epilepsy patients, however they may provide extensive information on brain pathology, allowing the analysis of areas beyond the putative epileptogenic zone. In this article, we reviewed pathology studies performed in epilepsy patients with emphasis on neuropathological findings in TLE with MTS and MCD. Furthermore, we reviewed data from postmortem studies and discussed the importance of performing these studies in epilepsy populations.

A epilepsia é um transtorno do funcionamento cerebral caracterizado por crises epilépticas recorrentes que acomete cerca de 1 a 2% da população mundial. A epilepsia do lobo temporal (ELT) é o subtipo mais prevalente. A refratariedade aos medicamentos é comum e cerca de 40 % destes pacientes apresentam transtornos psiquiátricos. Neste trabalho utilizamos o método de TacMan real time PCR para quantificar o mRNA de subtipos dos receptores de noradrenalina, dopamina, serotonina e substância P em hipocampos cirurgicamente removidos de pacientes com ELT para conhecer o papel destes na ELT com ou sem comorbidade psiquiátrica (depressão ou psicose). Nossa amostra foi de 48 pacientes com ELT sem (Epilepsia - 24) ou com comorbidade psicótica (Psicose - 10) ou depressiva (Depressão - 14) e 8 Controles (necrópsias). O receptor adrenérgico-α2A (AD2A) apresentou diferença entre os grupos (p = 0,0059) com significância para a variável Antiepiléptico (p = 0,0374) e pós-teste significante de maior expressão do mRNA de AD2A no grupo Epilepsia comparado com Controle e com Psicose. A ativação dos receptores α2A no hipocampo pelos antiepilépticos pode explicar nossos achados do grupo Epilepsia comparado ao Controle, corroborando a literatura acerca do AD2A na epilepsia e em relação aos antiepilépticos. O AD2C mostrou diferença entre os grupos (p = 0...

INTRODUÇÃO: As relações entre sono e epilepsia são complexas e de grande importância clínica. A melhor compreensão das inúmeras lacunas que permeiam essa relação reforçaria os alicerces para o desenvolvimento de abordagens terapêuticas mais eficazes que pudessem contribuir para o bem-estar do paciente portador de epilepsia e transtornos do sono. OBJETIVO: O presente estudo teve como principal objetivo o estudo comportamental e a caracterização eletrofisiológica do ciclo vigília-sono (CVS) de ratos adultos tornados epilépticos por pilocarpina. MÉTODO: Ratos Wistar machos (N=6), tornados epilépticos após status epilepticus (SE) induzido por pilocarpina e não epilépticos (N=6) foram submetidos à cirurgia extereotáxica para implante de elétrodos bipolares nas áreas corticais (A3, somatosensorial) e hipocampais (CA1) de ambos os hemisférios. Registros contínuos de 24 horas foram submetidos à minuciosa análise visual e os seguintes parâmetros foram analisados: identificação e quantificação dos padrões eletrofisiológicos das fases do ciclo CVS; duração dos episódios oníricos ocorridos durante o sono dessincronizado (SD); padrão de ocorrência do CVS assim como do ciclo de sono (CS), e análise do volume do núcleo supraquiasmático. Os estudos da distribuição do CVS e comportamento onírico foram submetidos à Análise de Variância Multivariada - MANOVA...

O statistical parametric mapping (SPM) é uma ferramenta de quantificação que tem sido usada no SPECT de perfusão cerebral (SPECT), mas apenas poucos trabalhos na literatura comparam a sua sensibilidade com a da análise visual em pacientes com epilepsia de lobo temporal (ELT) OBJETIVO: Avaliar a capacidade da análise com SPM no SPECT em detectar o foco epileptogênico e alterações perfusionais em regiões extra-temporais em pacientes com epilepsia de lobo temporal mesial (ELTM), comparando os seus achados com os da análise visual MÉTODOS: Foram realizados SPECTs ictal e interictal em 22 pacientes com ELTM refratários ao tratamento clínico. O lado do foco epileptogênico foi definido com base na história clínica, ressonância magnética, eletroencefaiogramas seriados e telemetria. Os SPECTs foram submetidos à análise visual sendo que os SPECTs interictal e ictal foram analisados em conjunto pelos observadores (SPECT-visual-inter e SPECT-visual-ictal). Foi aplicado o SPM2 que comparou os pacientes com um grupo controle de 50 indivíduos normais. No SPM foram realizadas as seguintes comparações: grupo de SPECT interictal com o grupo controle (SPM-grupo-inter); SPECT interictal de cada paciente com o grupo controle (SPM-indiv-inter); grupo de SPECT ictal com o grupo controle (SPM-grupo-ictal); SPECT ictal de cada paciente com o grupo controle (SPM-indiv-ictal). Foram também comparadas as intensidades das alterações perfusionais nos lobos temporais procurando-se por um aumento da perfusão no SPECT ictal em relação ao interictal (SPM-indiv-ictal/inter). RESULTADOS: Não foi observada nenhuma alteração perfusional significativa no SPM-grupo-inter Já no SPM-grupo-ictal o foco epileptogênico foi a região de hiperperfusão mais significativa No SPM-indiv-inter a sensibilidade na localização do foco foi de 45% e no SPM-indiv-ictal a sensibilidade foi de 64%. O SPM-indiv-ictal/inter apresentou a maior sensibilidade para detectar o foco dentre as análises realizadas no SPM (77%) A sensibilidade do SPECT-visual-inter foi de 68% e para o SPECT-visuai-ictal foi de 100%.

26 patients with temporal lobe epilepsy clinically documented by several abnormal interictal surface EEGs with typical unitemporal epileptiform activity and a normal CT scan were studied. Interictal99mTC HMPAO brain SPECT and MRI were performed in all subjects. Abnormalities were shown in 61.5% of MRI (n=16) and 65.4% of SPECT (n=17). Hippocampal atrophy associated to a high signal on T2-weighted MRI slices suggesting mesial temporal sclerosis was the main finding (n=12; 75% of abnormal MRI). MRI correlated well to surface EEG in 50% (n=13). There was also a good correlation between MRI and SPECT in 30.7% (n=8). SPECT and EEG were in agreement in 57.7% (n=l5). MRI, SPECT and EEG were congruent in 26.9% (n=7). These results support the usefulness of interictal brain SPECT and MRI in detecting lateralized abnormalities in temporal lobe epilepsy. On the other hand, in two cases, interictal SPECT correlated poorly with surface EEG. This functional method should not be used isolately in the detection of temporal lobe foci. MRI is more useful than CT as a neuroimaging technique in temporal lobe epilepsy. It may detect small structural lesions and mesial temporal lobe sclerosis which are not easily seen with traditional CT scanning.

The functional significance of MRI-defined mesial temporal sclerosis in temporal lobe epilepsy (TLE) is not completely established. In order to study the possible relationship between signals of mesial temporal sclerosis on MRI and interictal SPECT findings we selected 18 patients with complex partial seizures, unilateral temporal EEG focus and normal CT. The EEG focus was defined by the presence of interictal sharp waves and slow background on several scalp EEG obtained during many years of follow up in all patients and by ictal recordings with sphenoidal electrodes in 12 patients. Group I comprised patients (n=11) in whom MRI showed mesial temporal sclerosis; group II patients (n=7) had normal MRIs. All patients were submitted to interictal 99m-Tc HMPAO injections with concomitant EEG monitoring. Lateralized hypoperfusion ipsilateral to the EEG was found in 13 patients (72%). In all Group II and in 6 Group I patients a temporal hypoperfusion was found. This SPECT study showed a higher positivity rate in patients with normal MRI than previously reported. On the other hand, in all these group II patients a neocortical origin of epileptic focus was suspected on clinical or electroencephalographic basis. Positive SPECT findings may be at least as prevalent in neocortical as in mesiolimbic epilepsy.

INTRODUCTION: Surgical planning for refractory medial temporal lobe epilepsy (rMTLE) relies on seizure localization by ictal electroencephalography (EEG). Multiple factors impact the number of seizures recorded. We evaluated whether seizure freedom correlated to the number of seizures recorded, and the related factors. METHODS: We collected data for 32 patients with rMTLE who underwent anterior temporal lobectomy. Primary analysis evaluated number of seizures captured as a predictor of surgical outcome. Subsequent analyses explored factors that may seizure number. RESULTS: Number of seizures recorded did not predict seizure freedom. More seizures were recorded with more days of seizure occurrence (p<0.001), seizure clusters (p<0.011) and poorly localized seizures (PLSz) (p=0.004). Regression modeling showed a trend for subjects with fewer recorded poorly localized seizures to have better surgical outcome (p=0.052). CONCLUSIONS: Total number of recorded seizures does not predict surgical outcome. Patients with more PLSz may have worse outcome.

Objective Patients with mesial temporal lobe epilepsy (MTLE) may present unstable pattern of seizures. We aimed to evaluate the occurrence of relapse-remitting seizures in MTLE with (MTLE-HS) and without (MTLE-NL) hippocampal sclerosis. Method We evaluated 172 patients with MTLE-HS (122) or MTLE-NL (50). Relapse-remitting pattern was defined as periods longer than two years of seizure-freedom intercalated with seizure recurrence. “Infrequent seizures” was considered as up to three seizures per year and “frequent seizures” as any period of seizures higher than that. Results Thirty-seven (30%) MTLE-HS and 18 (36%) MTLE-NL patients had relapse-remitting pattern (X2, p = 0.470). This was more common in those with infrequent seizures (X2, p < 0.001). Twelve MTLE-HS and one MTLE-NL patients had prolonged seizure remission between the first and second decade of life (X2, p = 0.06). Conclusion Similar proportion of MTLE-HS or MTLE-NL patients present relapse-remitting seizures and this occurs more often in those with infrequent seizures.

Background : In medial temporal lobe epilepsy (MTLE), previous studies addressing the hemispheric laterality of epileptogenic focus and its relationship with learning and memory processes have reported controversial findings. Objective : To compare the performance of MTLE patients according to the location of the epileptogenic focus on the left (MTLEL) or right temporal lobe (MTLER) on tasks of episodic learning and memory for verbal and visual content. Methods : One hundred patients with MTLEL and one hundred patients with MTLER were tested with the following tasks: the Rey Auditory Verbal Learning Test (RAVLT) and the Logical Memory-WMS-R to evaluate verbal learning and memory; and the Rey Visual Design Learning Test (RVDLT) and the Visual Reproduction-WMS-R to evaluate visual learning and memory. Results : The MTLEL sample showed significantly worse performance on the RAVLT (p < 0.005) and on the Logical Memory tests (p < 0.01) than MTLER subjects. However, there were no significant between-group differences in regard to the visual memory tests. Discussion : Our findings suggest that verbal learning and memory abilities are dependent on the structural and functional integrity of the left temporal lobe, while visual abilities are less dependent on the right temporal lobe.

OBJECTIVE: To analyze seizure outcome in individuals with familial mesial temporal lobe epilepsy (FMTLE). METHOD: We followed prospectively 64 individuals with FMTLE and 37 asymptomatic individuals belonging to 28 families. RESULTS: Patients with FMTLE had a mean follow up was 93.4 ± 15.8 months. At baseline they were divided in benign (n = 29), remission (n = 28) and refractory (n = 7). At last follow up visit 41.4% patients with benign FMTLE remained classified as benign, 20.7% became refractory and 37.9% were in remission. In the subgroup of FMTLE in remission 21 75% remained without seizures; 21.4% were classified as benign FMTLE, and one died (3.6%) from cause unrelated to epilepsy. All refractory patients remained refractory. From the asymptomatic group, 10.8% became symptomatic (FMTLE). The mean follow up was 76.0 ± 21.2 months. CONCLUSION: Prospective follow up of more than 7 years in patients with FMTLE revealed that it is unlikely to achieve seizure control in those with refractory seizures. Patients with diagnose of more benign forms of FMTLE for more than one year are likely to either remit or remain under well controlled seizures. The majority of patients who had achieved seizure remission remained seizure-free and none became refractory. Asymptomatic individuals had a greater probability to have seizures compared to the general population in a 6 year period of follow up.

OBJECTIVES: Patients that undergo epilepsy surgery for temporal lobe epilepsy (TLE) in the dominant hemisphere are more susceptible to naming deficits. The aim of the present study was to perform an observational retrospective study comparing two groups of patients for naming performance, those with left and right temporal lobe resections regarding the performance in naming by Boston Naming Test (BNT). METHODS: A total of 120 right-handed patients (52 right temporal lobe and 68 left temporal lobe), aged between 18 and 59, with pharmacoresistant mesial TLE were retrospectively analyzed. All patients underwent pre and postoperative neuropsychological assessment. RESULTS AND CONCLUSIONS : The BNT was a good predictor for possible post-surgical language deficits in patients submitted to left temporal lobectomy.

The mesial temporal lobe (MTL) is typically understood as a memory structure in clinical settings, with the sine qua non of MTL damage in epilepsy being memory impairment. Recent models, however, understand memory as one of a number of higher cognitive functions that recruit the MTL through their reliance on more fundamental processes, such as “self-projection” or “association formation”. We examined how damage to the left MTL influences these fundamental processes through the encoding of elemental spatial and temporal associations. We used a novel fMRI task to image the encoding of simple visual stimuli, either rich or impoverished, in spatial or spatial plus temporal information. Participants included 14 typical adults (36.4 years, sd. 10.5 years) and 14 patients with left mesial temporal lobe damage as evidenced by a clinical diagnosis of left temporal lobe epilepsy (TLE) and left MTL impairment on imaging (34.3 years, sd. 6.6 years). In-scanner behavioral performance was equivalent across groups. In the typical group whole-brain analysis revealed highly significant bilateral parahippocampal activation (right > left) during spatial associative processing and left hippocampal/parahippocampal deactivation in joint spatial-temporal associative processing. In the left TLE group identical analyses indicated patients used MTL structures contralateral to the seizure focus differently and relied on extra-MTL regions to a greater extent. These results are consistent with the notion that epileptogenic MTL damage is followed by reorganization of networks underlying elemental associative processes. In addition...

SCN1B, the gene encoding the sodium channel ß 1 subunit, was the first gene identified for generalized epilepsy with febrile seizures plus (GEFS+). Only three families have been published with SCN1B mutations. Here, we present four new families with SCN1B mutations and characterize the associated phenotypes. Analysis of SCN1B was performed on 402 individuals with various epilepsy syndromes. Four probands with missense mutations were identified. Detailed electroclinical phenotyping was performed on all available affected family members including quantitative MR imaging in those with temporal lobe epilepsy (TLE). Two new families with the original C121W SCN1B mutation were identified; novel mutations R85C and R85H were each found in one family. The following phenotypes occurred in the six families with SCN1B missense mutations: 22 febrile seizures, 20 febrile seizures plus, five TLE, three other GEFS+ phenotypes, two unclassified and ten unaffected individuals. All individuals with confirmed TLE had the C121W mutation; two underwent temporal lobectomy (one with hippocampal sclerosis and one without) and both are seizure free. We confirm the role of SCN1B in GEFS+ and show that the GEFS+ spectrum may include TLE alone. TLE with an SCN1B mutation is not a contraindication to epilepsy surgery.; Ingrid E. Scheffer...

Epilepsia do lobo temporal (ELT) é a forma mais comum de epilepsia em adultos. O processo de epileptogênese inclui a morte neuronal, brotamento axonal, inflamação, neurogênese, estresse oxidativo e gliose. No entanto, os mecanismos moleculares subjacentes não são totalmente compreendidos. Os fatores de crescimento de fibroblastos (FGFs) são uma família de proteínas com várias funções no organismo, especialmente no sistema nervoso central. No entanto, o funcionamento dos FGFs no cérebro humano não é totalmente compreendido. O FGF2 é o membro mais estudado dessa família e seu papel na fisiopatologia da epilepsia é controversa. Na tentativa de esclarecer o envolvimento da via de FGF na ELT, nós quantificamos a expressão hipocampal dos seguintes genes: FGF2, FGF8, FGF22, FGFR1, FGFR2, FGFR3, ITPR3, PIK3R3 e PIK3R5 em 10 pacientes resistentes a fármacos e quatro controles post mortem. Além disso, avaliamos a expressão da proteína de FGF2 por imunofluorescência indireta. Apenas para o FGF2, houve aumento do RNAm no hipocampo dos pacientes para os dois genes de referência testados, HPRT1 e ENO2 + TBP em combinação (P = 0,002 e P = 0,036; respectivamente). A porcentagem de células imunomarcadas para FGF2 no giro dentado foi maior nos pacientes do que nos controles (P <0...

OBJECTIVE: To analyze retrospectively a series of patients with temporal lobe epilepsy (TLE) and mesial temporal sclerosis (MTS), and the association of patterns of hippocampal sclerosis with clinical data and surgical prognosis. METHOD: Sixty-six patients with medically refractory TLE with unilateral MTS after anterior temporal lobectomy were included. Quantitative neuropathological evaluation was performed on NeuN-stained hippocampal sections. Patient's clinical data and surgical outcome were reviewed. RESULTS: Occurrence of initial precipitating insult (IPI), as well as better postoperative seizure control (i.e. Engel class 1), were associated with classical and severe patterns of hippocampal sclerosis (MTS type 1a and 1b, respectively). CONCLUSION: Quantitative evaluation of hippocampal neuronal loss patterns predicts surgical outcome in patients with TLE-MTS.
