Do Hippocampal Neurons Really Count for Comorbid Depression in Patients With Mesial Temporal Lobe Epilepsy and Hippocampal Sclerosis? A Histopathological Study.

Depression is the most frequent psychiatric comorbidity seen in mesial temporal lobe epilepsy (MTLE) patients with hippocampal sclerosis (HS). Moreover, the HS is the most frequent pathological hallmark in MTLE-HS. Although there is a well-documented hippocampal volumetric reduction in imaging studies of patients with major depressive disorder, in epilepsy with comorbid depression, the true role of the hippocampus is not entirely understood. This study aimed to verify if patients with unilateral MTLE-HS and the co-occurrence of depression have differences in neuronal density of the hippocampal sectors CA1-CA4. For this purpose, we used a histopathological approach. This was a pioneering study with patients having both clinical disorders. However, we found no difference in hippocampal neuronal density when depression co-occurs in patients with epilepsy. In this series, CA1 had the lowest counting in both groups, and HS ILAE Type 1 was the most prevalent. More studies using histological assessments are needed to clarify the physiopathology of depression in MTLE-HS.

Impulsiveness, personality traits and executive functioning in patients with juvenile myoclonic epilepsy.

PURPOSE: To evaluate impulsiveness in adult patients with JME and its relationship with personality traits and executive functioning. METHODS: Patients completed psychiatric evaluation (DSM IV), Barratt Impulsiveness Scale (BIS-11), Neo Revised Personality Inventory (NEO PI-R) and executive functioning evaluation comprising Controlled Oral Word Association (COWA), Digit Span, Trail Making Tests (TMT), Stroop Test (ST) and Wisconsin Card Sorting Test (WSCT). Healthy controls (63 % female, mean age 35.7 yrs. (±8.37)) were examined to allow calculation of z-scores. RESULTS: 50 patients (70 % female; mean age 32.5 yrs. (±9.2)) presented higher scores of Total (z=-0.37; p = 0.005) and Motor Impulsiveness (z=-0.79; p < 0.001) on BIS-11. Motor Impulsiveness was associated with higher rates of mild psychiatric disorders (depression and anxiety) (p = 0.035) and worse myoclonic seizure control (p = 0.007). NEO PI-R showed differences on Neuroticism (z=-0.60; p < 0.001), Openness (z = 0.38; p = 0.043), Agreeableness (z=-0.38; p = 0.033) and Conscientiousness (z=-0.53; p = 0.003). There were positive correlations between BIS-11 and Neuroticism with Total, Motor and Non-Planning Impulsiveness, on the other hand, Conscientiousness was negatively correlated with these as well as with Attentive Impulsiveness. Patients performance was worse than that of controls on COWA (z=-0.43; p = 0.009) and WCST's Total Number of Completed Categories (z=-2.08; p = 0.005), Trials Taken to Complete First Category (z=-1.56; p = 0.013), Percentage of Total Errors (z=-1.56; p < 0.001), Perseverative Errors (z=-0.73; p = 0.002), Non-Perseverative Errors (z=-1.05; p = 0.003) and Conceptual Level Responses (z=-1.52; p < 0.001). Non-Planning Impulsiveness correlated with Performance (ST and TMT). CONCLUSION: Patients with JME present with impulsive behavior, personality features and executive dysfunction which are linked and may lead to lack of commitment in treatment and affect other aspects of life.

Neuropsychological findings related to the presence of pre-surgical comorbid depression in Latin-American patients with mesial temporal lobe epilepsy and hippocampal sclerosis.

PURPOSE: To evaluate the neuropsychological findings related to the presence of pre-surgical comorbid depression in Latin-American patients with mesial temporal lobe epilepsy (MTLE) and unilateral hippocampal sclerosis (HS). METHOD: Patients with drug-resistant MTLE and unilateral, left (L-) or right (R-) HS were studied. To diagnose depression, psychiatrists with expertise in epilepsy applied a semi-structured interview based on DSM. The depression group (DG) included patients with a psychiatric diagnosis in addition to a Beck Depression Inventory (BDI) score >16 points, and the non-depression group (NDG) included those without this diagnosis and with a BDI score ≤16. We analysed two clusters of neuropsychological tests, which evaluated memory (Complex Rey Figure III, Logical Memory II and RAVLT VII) and attention plus executive functions (Stroop I/II/III and Trail Making A/B). Moreover, we calculated the z-scores (Zs) using a local control group. The DG was compared to the NDG, independently and according to the HS side, using non-parametrical analyses. Due to the multivariate analysis, the p-value was corrected by applyingpost hoc Bonferroni adjustment. RESULTS: We analysed 65 patients. The NDG included 51 (78.4 %) patients, and the DG included 14 (21.5 %) patients. Pre-surgical comorbid depression occurred in eight patients with L- (n = 29) and in six patients with R-MTLE-HS (n = 36). All of these groups had similar gender, age, IQs, and years of schooling. Compared to the healthy subjects, the L-MTLE-HS patients had lower Zs in verbal episodic memory tests [Logical Memory II (p < 0.001), and RAVLT VII (p < 0.001)], and the R-MTLE-HS patients had lower scores in visual episodic memory [Complex Rey Figure III (p < 0.001)]. In the analysis of the DGvs. NDG, there were no differences in the clusters of tests of memory or in those of attention and executive functions. Moreover, when we analysed the patients according to HS side, no neuropsychological difference was observed in the DG and NDG in terms of L- and R-MTLE-HS. CONCLUSIONS: The patients with MTLE and unilateral HS in this study showed no differences in memory, attention and executive functions in relation to the presence of pre-surgical comorbid depression and independently of HS side. In this series from Latin-America, this psychiatric comorbidity did not affect cognition more than epilepsy alone.

Dysfunctional personality beliefs and executive performance in patients with juvenile myoclonic epilepsy.

BACKGROUND: This article intends to verify the association of dysfunctional beliefs of personality disorders with the executive performance in people with juvenile myoclonic epilepsy (JME). METHODS: Fifty-two patients (35 women, 67.3%) with JME aged 18-50 yrs. (32.3 ±â€¯9.7) were evaluated between May 2017 and April 2018 and compared with controls. All subjects were submitted to the Personality Beliefs Questionnaire (PBQ) (Beck & Beck, 1991; Savoia et al., 2006), Dysexecutive Questionnaire (DQ; Wilson et al., 1996; Macuglia et al., 2016), estimated intelligence quotient (IQ) using Vocabulary and Block Design tests, attention and executive functions evaluation (Controlled Oral Word Association (COWA), Digit Span, Trail Making Tests (TMT) A and B, Stroop and Wisconsin Card Sorting Test (WCST)). The inclusion criteria were as follows: diagnosis of JME (ILAE, 1989); age ≥18 yrs., schooling ≥ 11 yrs. and IQ ≥70. The inclusion criteria for the control group were the same except diagnosis of epilepsy. RESULTS: Compared with controls, patients presented higher scores in PBQ for personality disorders, namely Narcissistic (z = -0.79; p < 0.001), Borderline (z = -0.58; p = 0.002), Paranoid (z = -0.43; p = 0.017), and Histrionic (z = -0.39; p = 0.041). Executive functions were impaired when compared with controls in TMT A (z = -0.97; p = 0.038), TMT B (z = -0.65; p = 0.023), and COWA (z = -0.51; p = 0.001). Patients showed higher WCST scores for Errors (z = -1.62; p ≤ 0.001), Perseverative Errors (z = -0.77; p = 0.001), Non-Perseverative Errors (z = -1.01; p = 0.001), Conceptual Level Response (z = -1.56; p ≤ 0.001), Completed Categories (z = -2.12; p = 0.002), and Failure to Maintain Context (z = -0.49; p = 0.015). Personality Beliefs Questionnaire results showed correlation with lower values in TMT A, Antisocial (r = -0.298; p = 0.032), Narcissistic (r = -0.303; p = 0.029), Schizoid (r = - 0.410; p = 0.003), Histrionic (r = -0.341; p = 0.013), Passive-aggressive (r = -0.341; p = 0.015), and Obsessive-compulsive (r = -0.319; p = 0.021); TMT B results showed a trend for Obsessive-compulsive traits (r = -0.261; p = 0.052); COWA was correlated to Dependent (r = 0.319; p = 0.021); and Digit Span to Passive-aggressive (r = 0.287; p = 0.039). On WCST, Failure to Maintain Context was correlated to Avoidant (r = 0.335; p = 0.017). The DQ was not correlated with PBQ. CONCLUSION: People with JME presented dysfunctional beliefs of personality disorder that were correlated with executive dysfunction. These findings reinforce the need for psychological rehabilitation in these patients.

Morphometric MRI features and surgical outcome in patients with epilepsy related to hippocampal sclerosis and low intellectual quotient.

OBJECTIVE: The objectives of this study were to verify in a series of patients with mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) if those with low intellectual quotient (IQ) levels have more extended areas of atrophy compared with those with higher IQ levels and to analyze whether IQ could be a variable implicated on a surgical outcome. MATERIAL AND METHODS: Patients (n=106) with refractory MTLE-HS submitted to corticoamygdalohippocampectomy (CAH) (57 left mesial temporal lobe epilepsy (MTLE); 45 males) were enrolled. To determine if the IQ was a predictor of seizure outcome, totally seizure-free (SF) versus nonseizure-free (NSF) patients were evaluated. FreeSurfer was used for cortical thickness and volume estimation, comparing groups with lower (<80) and higher IQ (90-109) levels. RESULTS: In the whole series, 42.45% of patients were SF (Engel Class 1a; n=45), and 57.54% were NSF (n=61). Total cortical volume was significantly reduced in the group with lower IQ (p=0.01). Significant reductions in the left hemisphere included the following: rostral middle frontal (p=0.001), insula (p=0.002), superior temporal gyrus (p=0.003), thalamus (p=0.004), and precentral gyrus (p=0.02); and those in the right hemisphere included the following: rostral middle frontal (p=0.003), pars orbitalis (p=0.01), and insula (p=0.02). Cortical thickness analysis also showed reductions in the right superior parietal gyrus in patients with lower IQ. No significant relationship between IQ and seizure outcome was found. CONCLUSIONS: This is the first study of a series of patients with pure MTLE-HS, including those with low IQ and their morphometric magnetic resonance imaging (MRI) features using FreeSurfer. Although patients with lower intellectual scores presented more areas of brain atrophy, IQ was not a predictor of surgical outcome. Therefore, when evaluating seizure follow-up, low IQ in patients with MTLE-HS might not contraindicate resective surgery.

Impact of hippocampal subfield histopathology in episodic memory impairment in mesial temporal lobe epilepsy and hippocampal sclerosis.

OBJECTIVE: The objective of the study was to analyze preoperative visual and verbal episodic memories in a homogeneous series of patients with mesial temporal lobe epilepsy (MTLE) and unilateral hippocampal sclerosis (HS) submitted to corticoamygdalohippocampectomy and its association with neuronal cell density of each hippocampal subfield. METHODS: The hippocampi of 72 right-handed patients were collected and prepared for histopathological examination. Hippocampal sclerosis patterns were determined, and neuronal cell density was calculated. Preoperatively, two verbal and two visual memory tests (immediate and delayed recalls) were applied, and patients were divided into two groups, left and right MTLE (36/36). RESULTS: There were no statistical differences between groups regarding demographic and clinical data. Cornu Ammonis 4 (CA4) neuronal density was significantly lower in the right hippocampus compared with the left (p=0.048). The groups with HS presented different memory performance - the right HS were worse in visual memory test [Complex Rey Figure, immediate (p=0.001) and delayed (p=0.009)], but better in one verbal task [RAVLT delayed (p=0.005)]. Multiple regression analysis suggested that the verbal memory performance of the group with left HS was explained by CA1 neuronal density since both tasks were significantly influenced by CA1 [Logical Memory immediate recall (p=0.050) and Logical Memory and RAVLT delayed recalls (p=0.004 and p=0.001, respectively)]. For patients with right HS, both CA1 subfield integrity (p=0.006) and epilepsy duration (p=0.012) explained Complex Rey Figure immediate recall performance. Ultimately, epilepsy duration also explained the performance in the Complex Rey Figure delayed recall (p<0.001). SIGNIFICANCE: Cornu Ammonis 1 (CA1) hippocampal subfield was related to immediate and delayed recalls of verbal memory tests in left HS, while CA1 and epilepsy duration were associated with visual memory performance in patients with right HS.

Migraine and cognition in children: a controlled study.

OBJECTIVE: Evaluate the cognitive functions of children with migraine and compare them to A control group. METHOD: 30 migraineur children and 30 control group children without migraine, age ranging from 8 to 12 years old, were subjected to a cognitive functions assessment with Wechsler Intelligence Scale for Children (WISCIII). RESULTS: Although both groups had a normal cognitive performance, children with migraine had significantly worse scores compared to the control group in the subtests of Information, Arithmetic, Vocabulary, Object Assembly and in the Indexes of Perceptual Organization, Resistance to Distraction and Processing Speed. CONCLUSION: Children with migraine had impairment in some cognitive functions such as attention, memory, information speed, and perceptual organization compared to the control group.

OBJECTIVE: Evaluate the cognitive functions of children with migraine and compare them to A control group. METHOD: 30 migraineur children and 30 control group children without migraine, age ranging from 8 to 12 years old, were subjected to a cognitive functions assessment with Wechsler Intelligence Scale for Children (WISCIII). RESULTS: Although both groups had a normal cognitive performance, children with migraine had significantly worse scores compared to the control group in the subtests of Information, Arithmetic, Vocabulary, Object Assembly and in the Indexes of Perceptual Organization, Resistance to Distraction and Processing Speed. CONCLUSION: Children with migraine had impairment in some cognitive functions such as attention, memory, information speed, and perceptual organization compared to the control group.

OBJETIVO: Avaliar as funções cognitivas de crianças com e sem migrânea, utilizando a Escala de Inteligência Wechsler para Crianças (WISC-III). MÉTODO: A amostra foi composta por 30 crianças com diagnóstico de migrânea na idade entre 8 a 12 anos e grupo controle de 30 crianças sem migrânea na mesma faixa etária. Todas foram avaliadas pela Escala de WISC-III. RESULTADOS: Embora ambos os grupos tenham demonstrado um quociente de inteligência dentro da média, as crianças com migrânea, quando comparados aos controles, tiveram desempenho inferior nos subtestes de Informação, Aritmética, Vocabulário, Armar Objetos e nos Índices de Compreensão verbal, Organização Perceptual, Resistência à Distração e Velocidade de Processamento. CONCLUSÃO: Quando comparadas aos controles, crianças com migrânea apresentaram desempenhos inferiores em vários domínios cognitivos como atenção, velocidade de processamento, memória e organização perceptual.

Assessment of working memory in patients with mesial temporal lobe epilepsy associated with unilateral hippocampal sclerosis.

OBJECTIVE: The aim of the present study was to investigate whether working memory is impaired in mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS), a controversial and largely unexplored matter. METHODS: Twenty subjects with left MTLE-HS, 19 with right MTLE-HS, and 21 control right-handed subjects underwent neuropsychological assessment of episodic and semantic memory, executive functions, and specific working memory components. RESULTS: Left and right epileptogenic foci resulted in impairment of verbal and nonverbal episodic memory (verbal memory deficit greater in left MTLE-HS than in right MTLE-HS). In addition, patients with left MTLE-HS were impaired in learning paired associates, verbal fluency, and Trail Making. No differences were seen in the tests carried out to evaluate the working memory components (except visuospatial short-term memory in right MTLE-HS). CONCLUSION: In this study we did not detect reliable working memory impairment in patients with MTLE-HS with either a left or right focus in most tasks considered as tests of working memory components.

Correlation between memory, proton magnetic resonance spectroscopy, and interictal epileptiform discharges in temporal lobe epilepsy related to mesial temporal sclerosis.

OBJECTIVE: The aim of the study described here was to examine the relationship between memory function, proton magnetic resonance spectroscopy ((1)H-MRS) abnormalities, and interictal epileptiform discharge (IED) lateralization in patients with temporal lobe epilepsy (TLE) related to unilateral mesial temporal sclerosis. METHODS: We assessed performance on tests of memory function and intelligence quotient (IQ) in 29 right-handed outpatients and 24 controls. IEDs were assessed on 30-minute-awake and 30-minute-sleep EEG samples. Patients had (1)H-MRS at 1.5 T. RESULTS: There was a negative correlation between IQ (P=0.031) and Rey Auditory Verbal Learning Test results (P=0.022) and epilepsy duration; between(1)H-MRS findings and epilepsy duration (P=0.027); and between N-acetylaspartate (NAA) levels and IEDs (P=0.006) in contralateral mesial temporal structures in the left MTS group. (1)H-MRS findings, IEDs, and verbal function were correlated. CONCLUSIONS: These findings suggest that IEDs and NAA/(Cho+Cr) ratios reflecting neural metabolism are closely related to verbal memory function in mesial temporal sclerosis. Higher interictal activity on the EEG was associated with a decline in total NAA in contralateral mesial temporal structures.

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.

Serial position curve and semantic facilitation in patients with mesial temporal lobe epilepsy / Curva de posição serial e facilitação semântica em pacientes com epilepsia de lobo temporal mesial / Curva de posición serial y facilitación semantica en pacientes con epilepsia del lóbulo temporal medial

We investigated the serial position curve and semantic facilitation effect in patients with left and right mesial temporal lobe epilepsy (MTLE) with hipocampal sclerosis compared to a matched control group. Subjects (L-MTLE = 19, R-MTLE = 15, and controls = 21) were assessed by recalling word lists either with the three middle wordssemantically related or not. The total number of words recalled from both types of lists did not differ between groups. Recency was preserved, showing that short-term memory (phonological loop) is not affected in these patients. Primacy was equally present for the lists with no semantic relationships in all groups, but was absent for lists with semantically related words. The semantic facilitation effect was seen in all groups, but with a lower magnitude in the L-MTLE group, suggesting that the spread of discharges in the left hemisphere interferes with the automatic processing of semantic networks.(AU)

Nós investigamos a curva de posição serial e o efeito de facilitação semântica em pacientes com epilepsia do lobo temporal mesial (ELTM) esquerda e direita com esclerose hipocampal, comparados a um grupo controle. Os sujeitos (ELTM-E = 19, ELTM-D = 15 e controles = 21) foram submetidos ao teste de recordação livre de palavras, sendo que metade das listas de palavras continham três palavras semanticamente relacionadas inseridas nas posições intermediárias. O número total de palavras recordadas em ambos tipos de listas não diferiu entre os grupos. A recência foi preservada sugerindo que a memória de curto prazo (alça fonológica) não é afetada nestes pacientes. A primazia foi observada somente nas listas sem relacionamento semântico, independentemente do grupo. O efeito de facilitação semântica foi obtido em todos os grupos, mas com menor magnitude ao ELTM-E, sugerindo que a propagação das descargas no hemisfério esquerdo interfere com o processamento automático da rede semântica.(AU)

Cognitive decline in temporal lobe epilepsy due to unilateral hippocampal sclerosis.

OBJECTIVE: We assessed the cognitive performance of patients with temporal lobe epilepsy (TLE) caused by unilateral hippocampal sclerosis (HS), in comparison with that of matched, healthy controls. We report the relationship between cognitive measures and duration of epilepsy, correlating with hippocampal volumes, and the impact of educational level on cognitive decline. METHODS: This study involved 61 outpatients (40 with < or = 8 years and 21 with >8 years of formal education) with unilateral HS and 61 controls. Volumetric MRI was performed on all patients and 10 controls. The results (mean, SD) of the neuropsychological tests of healthy subjects and patients were compared using the Student t and Mann-Whitney tests. RESULTS: Patients performed worse than controls in the neuropsychological evaluation. When adjusted z scores were used to calculate the impairment index, patients had a greater percentage of abnormal tests compared with controls. The cognitive decline, assessed through the impairment index, correlated with duration of epilepsy. Higher level of education did not protect against this decline, thus not supporting the hypothesis of cerebral reserve in this population. A significant correlation between hippocampal volumetric measures and duration of epilepsy was observed only in patients with left HS. CONCLUSION: Patients with TLE caused by HS present with cognitive morbidity that extends beyond memory deficits. Cognitive decline is associated with duration of epilepsy, and in patients with left-sided HS, duration may correlate with volumetric hippocampal loss.

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.

Neuropsychological assessment and quality of life in patients with refractory temporal lobe epilepsy related to hippocampal sclerosis

INTRODUCTION: Epilepsy is a disorder that results in abnormal activity in a group of neurons that may have significant impact on the normal cognitive processes and behavior. Temporal lobe epilepsy (TLE) is the most frequent form of partial epilepsy in adults, and hippocampal sclerosis (HS) the most common neuropathologic finding in patients with medically refractory TLE. Patients with TLE often present cognitive difficulties that may be determined by the effects of epileptic discharges and side of the lesion. And its consequence is that patients have poor effects on quality of life (QOL). PURPOSE: We report the relationship between neuropsychological assessment and QOL under the hypotheses that patients with worst results in neuropsychological assessment have poorer QOL assessed by the QOLIE-31. RESULTS: Regarding seizure frequency, 23 (46 percent) had had 1-5, 20 (40 percent) 6-10 and 7 (14 percent) more than 10 seizures/month. In relation to seizure types, 5 (10 percent) had had auras, 37 (74 percent) complex partial seizures and 8 (16 percent) partial evolving to generalized tonic-clonic seizures (GTCS). Neuropsychological evaluation had a positive correlation with QOLIE-31 domains. QOL evaluations had the worst scores in QOLIE-31 were in Cognitive Function (45.0) and Social Function (46.0). The best was Overall QOL (62.0). CONCLUSION: People with epilepsy have great impact on their QOL not only because of daily seizures but because of the impact seizures cause in their cognitive functions. TLE is an example of how refractory epilepsy can exterminate any possibilities of work, study and live in a society that discriminates someone with epilepsy who also presents cognitive decline.

INTRODUÇÃO: Epilepsia é um distúrbio decorrente de atividade anormal de um grupo de neurônios, causando grande impacto no processo cognitivo e comportamental do indivíduo. A epilepsia do lobo temporal (ELT) é o tipo de epilepsia parcial mais comum e a esclerose hipocampal (EH) o substrato neuropatológico mais freqüentemente encontrado em pacientes com epilepsia refratária. Pessoas com ELT apresentam declínio cognitivo que pode ser determinado pela localização das descargas e da lesão. E, além disso, também apresentam limitação na qualidade de vida (QV) pelas crises diárias. OBJETIVO: Avaliar a relação entre a avaliação neuropsicológica e QV com a hipótese de que pacientes com piores resultados na primeira têm pior QV determinada pelo QOLIE-31. RESULTADOS: Quanto à freqüência de crises, 23 pacientes (46 por cento) tiveram até 5 crises, 20 (40 por cento) de 6 a 10 e 7 (14 por cento) mais de 10 por mês. Quanto ao tipo de crises, 5 (10 por cento) apresentaram apenas auras, 37 (74 por cento) crises parciais complexas e 8 (16 por cento) crises parciais complexas com generalização secundária. Os resultados da avaliação neuropsicológica tiveram correlação positiva com os domínios do QOLIE-31. Nos domínios Aspectos Sociais com testes de função executiva, Preocupação com as Crises e Qualidade de Vida Global com testes de memória verbal e Bem-estar Emocional com os testes utilizados para cálculo do QI. CONCLUSÃO: Pessoas com epilepsia têm grande impacto na QV não apenas pelas limitações causadas pelas crises diárias, mas também pelo que estas causam em suas funções cognitivas. ELT é um exemplo de como uma epilepsia refratária pode acabar com qualquer possibilidade dessas pessoas procurarem um emprego, estudarem e viverem em uma sociedade que as discrimina pelo fato de ter epilepsia e um declínio cognitivo comprovado.

The Portuguese version of the Epilepsy Surgery Inventory (ESI-55): cross-cultural adaptation and evaluation of psychometric properties.

The purpose of this study was to develop a Portuguese version of the Epilepsy Surgery Inventory (ESI-55) and to assess its psychometric properties. Sixty patients with temporal lobe epilepsy related to unilateral mesial temporal sclerosis who underwent presurgical evaluation at the Universidade Federal de São Paulo (UNIFESP) formed the sample for this study. The psychometric properties of the ESI-55 included: reliability, validity, and responsiveness. Internal consistency was high in all domains (Cronbach's alpha ranging from 0.76 for Social Function to 0.88 for Physical Function) except Overall Quality of Life (alpha=0.45). Test-retest reliability after 1 week was good, with the intraclass correlation coefficient ranging from 0.79 (Energy/Fatigue) to 0.92 (Role Limitations due to Emotional Problems). Interrater reliability ranged from 0.84 (Cognitive Function) to 0.94 (Role Limitations due to Physical Problems). For construct validity, we verified a high correlation between the ESI-55 and Health Assessment Questionnaire-8 for the Physical Function domain (Pearson linear correlation=-0.84), and a moderate correlation for the Pain domain (P=-0.58), but for the other subscales no correlation was detected. Beck Depression Inventory and ESI-55 domains were highly statistically correlated (ANOVA: P<0.005), but there was no association of the Cognitive Function and Role Limitations due to Memory Problems subscales with neuropsychological evaluation (Pearson coefficient: P>0.05). With respect to demographic characteristics, a statistically significant correlation was observed for the variable educational level (Student t, P<0.005) and ESI-55 scores. There was a high correlation between seizure frequency and ESI-55 domains for clinical variables (ANOVA, P<0.005). Surgical treatment in this series improved health-related quality of life in the seizure-free group in three domains--Health Perception (1.24), Emotional Well-Being (1.32), and Energy/Fatigue (1.48)-as reflected by the standard response mean and the effect size of the sample. Our results support the psychometric properties of the Portuguese version of the ESI-55 as a measure of health-related quality of life.

Desempenho cognitivo de pacientes com epilepsia do lobo temporal e epilepsia mioclônica juvenil: avaliação por meio da Escala WAIS-III / Cognitive performance of patients with temporal lobe epilepsy and juvenile myoclonic epilepsy: evaluation through the Wechsler Intelligence Scale WAIS-III

OBJETIVOS: Comparar os resultados em uma prova cognitiva de pacientes com epilepsia com dois parâmetros: um fornecido pelas normas brasileiras e outro pelas norte-americanas, tendo em vista as diferenças culturais. MÉTODO: Quarenta e cinco pacientes adultos com diagnóstico de epilepsia foram submetidos à avaliação de nível intelectual por meio da Escala Wechsler de Inteligência, WAIS-III nos seguintes itens: Quociente de Inteligência Verbal (QI V), Quociente de Inteligência de Execução (QI E) e Quociente de Inteligência Total (QI T). As correções dos protocolos seguiram as normas brasileiras e as norte-americanas. RESULTADOS: Dos 45 pacientes, 30 tinham o diagnóstico de epilepsia do lobo temporal (ELT) por esclerose mesial temporal (EMT), 15 no hemisfério esquerdo e 15 no direito, e 15 de epilepsia mioclônica juvenil (EMJ). Em todos os 45 protocolos do WAIS-III os resultados de QI V, QI E e QI T foram maiores quando empregados os parâmetros brasileiros. Assim, 18 pacientes que alcançaram QI T nas faixas "Média" e "Média Inferior", segundo as normas brasileiras, obtiveram níveis inferiores quando corrigidos pelas normas norte-americanas, ou seja, o QI T destes mesmos pacientes caiu para as faixas "Limítrofe" e "Muito Rebaixado" respectivamente. Nos pacientes com ELT, as diferenças de pontos entre os QI V e QI E não foram concordantes quando cotejados por normas diferentes e em cinco deles o desempenho verbal foi maior do que o motor quando corrigidos pelas normas norte-americanas. Nos pacientes com EMJ, os valores do QI V e QI E foram maiores quando empregadas normas brasileiras. CONCLUSÃO: Os resultados da avaliação cognitiva pelo WAIS-III de pacientes com epilepsia mostram que a interpretação do nível intelectual é muito distinta quando corrigida segundo normas brasileiras ou norte-americanas. Há também diferença na análise qualitativa do desempenho intelectual, uma vez que o estudo das discrepâncias internas variou conforme a norma populacional utilizada.

To compare the results of a cognitive task of patients with epilepsy with two parameters: one provided by the Brazilian and the other by the US normative scores viewing the cultural differences. METHOD: Forty-five adult patients diagnosed with epilepsy were submitted to intellectual evaluation through the Wechsler Adult Intelligence Scale, WAIS-III, in the following items: Verbal Intelligence Quotient (V IQ), Performance Intelligence Quotient (P IQ) and Full Scale (FS IQ). The correction of the protocols followed the Brazilian and the US normative scores. RESULTS: Thirty out of the 45 patients were diagnosed with temporal lobe epilepsy (TLE) due to mesial temporal sclerosis (MTS), 15 in the left hemisphere and 15 in the right, and 15 with juvenile myoclonic epilepsy (JME). In all 45 WAIS protocols the results of the V IQ, P IQ and FS IQ were higher when the Brazilian parameters were employed. Therefore, 18 patients that achieved FS IQ in the "Average" and "Low Average" ranges, according to the Brazilian normative scores, got lower levels when corrected by the US normative scores, that is, the FS IQ of these 18 patients fell to the æBorderlineÆ and æExtremely LowÆ ranges respectively. In the patients with TLE, the differences in the scores between the V IQ and P IQ did not correspond when evaluated by different normative scores and in five of them the verbal was higher than the performance when corrected by the US normative scores. In the patients with JME, the values of V IQ and P IQ were higher when the Brazilian normative scores were employed. CONCLUSION: The results of the cognitive evaluation through the WAIS of patients with epilepsy showed that interpretation of the intellectual level is very dissimilar when corrected by the Brazilian or US normative scores. There is also a difference in the qualitative analysis of the intellectual performance since the study of the inner discrepancy varied according the population normative scores employed.

Técnicas projetivas gráficas: o ensino de técnicas projetivas gráficas no curso de Psicologia, em duas instituições, particular e pública

Este artigo tem como finalidade relatar uma experiência de ensino de técnicas projetivas gráficas, em duas instituições de ensino de Psicologia: pública e privada. As autoras tentam uma comparação entre os alunos que freqüentam os dois tipos de instituições acadêmicas. Enfatiza-se também as dificuldades dos professores frente a disciplina que tem características teórico-práticas e a visão preconceituosa dos alunos com relação aos Testes Psicológicos. E o quanto a experiência prática de atendimento em psicodiagnóstico acaba gerando no aluno, uma mudança no seu enfoque inicial. Este artigo, também tem como objetivo, relatar duas experiências de ensino de técnicas projetivas gráficas, num curso de Psicologia, bem como promover uma reflexão sobre o papel do professor e do aluno dentro deste contexto.O primeiro relato é sobre uma experiência de ensino que foi conduzida ao longo de 11 anos, com alunos dos últimos anos (4º e 5º) de uma faculdade particular de Psicologia, em São Paulo, capital. Nesta referida instituição de ensino, o aluno só entrava em contato com qualquer método projetivo no 4º ano, após um embasamento teórico razoável, principalmente de origem psicanalítica.O segundo relato diz respeito aos resultados de uma pesquisa inicial com alunos do 4º ano de Psicologia de uma escola pública também em São Paulo (IPUSP)(AU)

Especializaçäo funcional hemisférica na afasia motora: achados neurofisiológicos ao mapeamento eletrencefalográfico computadorizado sob estimulaçä sonora musical e verbal: estudo de dois casos / Hemispheric functional specialization in motor aphasia: neurophysiologic findings with electroencephalographic brain mapping during musical and oral sonours stimulation: study of 2 cases

Este estudo diz respeito à atividade elétrica cerebral durante estimulaçäo auditiva em dois pacientes afásicos, um com afasia clássica (lesäo no hemisfério esquerdo) e outro com afasia cruzada (lesäo no hemisfério direito). Ambos foram submetidos ao teste de estimulaçäo auditiva dicótica (consoante-vogal-consoante) e de audiçäo musical (canto gregoriano) durante mapeamento eletrencefalográfico cerebral. Encontramos, em ambos, grande proporçäo da frequência delta e potência no hemisfério näo lesado, durante a estimulaçäo dicótica e musical. Alé disso, foi observado aumento na frequência de atividade alfa somente no hemisfério näo lesado, restrito à regiäo do lobo temporal. Esses achados sugerem um interessante campo de pesquisa acerca da medida de correlatos neurofisiológicos de estimulaçäo auditiva e de atividade elétrica cerebral na afasia
