Electroencephalogram alterations associated with psychiatric disorders in temporal lobe epilepsy with mesial sclerosis: A systematic review.

Temporal lobe epilepsy (TLE) is the most frequent focal epilepsy in adults and has been associated with psychiatric disorders (PD), especially the TLE with mesial temporal sclerosis (MTS). Electroencephalogram (EEG) could help in locating the epileptogenic zone and supply information regarding cerebral electric activity in these patients. However, there is a scarcity of knowledge about the association between EEG findings and comorbid PD in TLE. The objective of this review was to proceed a systematic review about the association of interictal EEG findings and PD in patients with TLE-MTS. A PRISMA model was used, and MEDLINE, CENTRAL, LILACS, and CAPES databases were searched. Six articles were considered in this review based on the inclusion/exclusion criteria. Results showed few published studies and contradicting conclusions regarding the association of EEG and PD in TLE-MTS. We observed great heterogeneity regarding the populations analyzed, hindering the comparison between the studies found. Studies with greater methodological robustness are needed to better understand the role of EEG as a possible biomarker for PD in TLE-MTS.

Are psychogenic nonepileptic seizures risk factors for a worse outcome in patients with refractory mesial temporal epilepsy submitted to surgery? Results of a retrospective cohort study.

OBJECTIVE: The objective of this study was to verify if the presence of psychogenic nonepileptic seizures (PNES) could be a risk factor precluding corticoamygdalohippocampectomy (CAH) in patients with refractory temporal lobe epilepsy (TLE) and mesial temporal sclerosis (MTS) (TLE-MTS). METHODS: This retrospective cohort study analyzed medical data of patients with refractory TLE-MTS accompanied in a Brazilian epilepsy surgery center. Presurgical psychiatric evaluations were performed using the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. Engel's I classification two years after surgery was considered as a favorable outcome. RESULTS: Of the 81 patients initially included (65 females; 56.5%), 49 (60.5%) had TLE-MTS without PNES, 24 (29.7%) with TLE-MTS and PNES, and eight (9.8%) with PNES only, who were excluded from further statistical comparisons. Nine patients with PNES (37.5%) underwent CAH versus 35 (71.4%) without PNES (p = 0.005). Five patients (55.5%) with PNES versus 26 (74.3%) without PNES presented Engel I (p = 0.54). The relative risk (RR) was of 1.90 for patients without PNES to undergo CAH and of 1.33 to be at Engel I. CONCLUSIONS: In this study, PNES were associated with less CAH. There were no differences, however, regarding favorable postsurgical outcomes. These results highlight that the sole presence of PNES should not preclude CAH in patients with TLE-MTS, despite the necessity of careful presurgical psychiatric evaluation.

Effects of a psychotherapeutic group intervention in patients with refractory mesial temporal lobe epilepsy and comorbid psychogenic nonepileptic seizures: A nonrandomized controlled study.

PURPOSE: Psychogenic nonepileptic seizures (PNES) are paroxysmal episodes superficially resembling epileptic seizures but are not associated with any electrical abnormalities. Despite the existence of recent evidence addressing psychological interventions on PNES, there is a scarcity of studies investigating such interventions on patients with dual diagnoses, such as in temporal lobe epilepsy/mesial temporal sclerosis (TLE-MTS) with comorbid PNES; TLE-MTS is a very frequent epilepsy syndrome found in tertiary centers. We aimed to investigate the effects of a group psychotherapeutic intervention program based on cognitive-behavioral therapy (CBT) on patients dually diagnosed with TLE-MTS and PNES treated in a tertiary center. METHOD: Patients with TLE-MTS and PNES who were followed-up in a tertiary center were invited. The intervention consisted of eight weekly, semi-structured group meetings. The Brazilian versions of the Quality of Life Scale (SF-36), the Toronto Alexithymia Scale (TAS), the Hamilton Depression Scale (HAM-D), the Hamilton Anxiety Scale (HAM-A), and the Ways of Coping Checklist (WCC) were applied before and after the intervention. RESULTS: Forty-seven patients were enrolled (25 females; 53.2%). Psychiatric disorders (PD) were observed in all 47 patients (100%); Major Depressive Disorder (MDD) was the most frequent PD (24; 51.0%). There were improvements on quality of life (P = 0.003), decreased depression (P<0.0001) and anxiety symptoms (P = 0.02), decreased levels of alexithymia (P = 0.02) and a reduction in seizure frequency (P = 0.02) after the intervention. CONCLUSIONS: Present data suggest a positive impact of a group psychological intervention based on CBT in patients with TLE-MTS and PNES, highlighting this therapeutic possibility for this specific subgroup.

Gender differences in prevalence of psychiatric disorders, levels of alexithymia, and coping strategies in patients with refractory mesial temporal epilepsy and comorbid psychogenic nonepileptic seizures.

OBJECTIVE: The objective of this study was to investigate the psychological aspects and psychiatric disorders (PDs) in patients dually diagnosed with refractory temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS) with psychogenic nonepileptic seizures (PNES) treated in a tertiary center in order to find any gender differences in psychiatric, clinical, and sociodemographic characteristics. METHOD: Psychiatric assessment was performed through the Diagnostic and Statistical Manual for Psychiatric Disorders - 5th edition (DSM-5). The Brazilian versions of the Medical Outcomes Study 36 (SF-36), Toronto Alexithymia Scale (TAS-20), Hamilton Depression Scale (HAM-D), Hamilton Anxiety Scale (HAM-A), and Ways of Coping Checklist (WCC) were applied. RESULTS: Of the 47 patients enrolled (25 females; 53.2%), females were significantly more likely to have a history of previous psychiatric treatment (P=0.02), family history of epilepsy (P=0.01), and family history of PD (P=0.03). They also presented earlier onset of PNES (P=0.01) and higher PNES duration (P=0.02) compared with males. Major depressive disorder (MDD) was the most frequent PD (24; 51.0%). Females presented more psychiatric diagnoses (P<0.001), more diagnoses of MDD (P<0.001), and posttraumatic stress disorder (PTSD) (P<0.001). Several differences regarding quality of life, levels of alexithymia, anxiety/depressive symptoms, and coping strategies were observed between groups. CONCLUSIONS: There are significant gender differences in psychiatric, clinical, and sociodemographic aspects in a group of patients with TLE-MTS and PNES, as well as in quality of life, levels of alexithymia, anxiety/depressive symptoms, and coping strategies. These gender differences suggest that specific approaches might be adopted depending on the patient's gender and, consequently, their distinct psychological/psychiatric profile.

Oxidative stress in patients with refractory temporal lobe epilepsy and mesial temporal sclerosis: Possible association with major depressive disorder?

OBJECTIVE: The objective was to evaluate the genetic and biochemical profiles associated with oxidative stress (OS) in patients with temporal lobe epilepsy with mesial temporal sclerosis (TLE-MTS) and a healthy control group, and also to verify the possible existence of association between OS markers and psychiatric disorders (PD) in group with TLE-MTS. METHODS: Forty-six patients with refractory TLE-MTS and 112 healthy controls were included. Psychiatric evaluation occurred through Diagnostical and Statistical Manual of Mental Disorders (DSM-5) criteria. A peripheral blood sample was collected for analysis of glutathione S-transferase (GST) T1/M1 polymorphisms and serum levels of malondialdehyde (MDA) and antioxidant capacity equivalent to the trolox (TEAC), serum markers of OS. Student's t-test, Fisher's exact test, Chi-square test, and Analysis of Variance (ANOVA) were used, with a significance level of P<0.05. RESULTS: The PD were observed in 27 patients of the group with TLE-MTS (58.6%); major depressive disorder (MDD) was the most frequent. Serum levels of MDA (P<0.0001) and TEAC (P<0.0001) were higher in group with TLE-MTS. When patients with MDD were compared with patients without PD, significant differences were observed between MDA (P=0.002) and TEAC (P=0.003) serum levels. Patients with TLE-MTS and MDD presented higher levels when compared with patients with TLE-MTS without PD and with another PD except MDD. CONCLUSIONS: The present study observed significantly higher serum levels of MDA and of TEAC in patients with refractory TLE-MTS in comparison with the control group. The MDD was observed as an important issue associated with higher OS levels in refractory TLE-MTS. Further studies are needed to investigate the association of OS, TLE-MTS, and PD.

Clinical and sociodemographic variables associated with interictal dysphoric disorder and interictal personality in patients with drug-resistant temporal lobe epilepsy: A controlled study.

Psychiatric disorders (PD) have an elevated prevalence and an important negative impact on patients with epilepsy (PWE) since they are associated with lower quality of life and clinical refractoriness. However, it is also necessary to identify behavioral conditions possibly associated with epilepsy that are not part of the standard psychiatric classifications, such as Interictal Dysphoric Disorder (IDD) and Interictal Personality (IP). The frequency of IDD and IP in patients with drug-resistant temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS) was assessed. The Brazilian versions of the Neurobehavioral Inventory (NBI) and Interictal Dysphoric Disorder Inventory (IDDI) were applied to patients and to a control group. Psychiatric standard assessment was conducted through the Diagnostic and Statistical Manual for Psychiatric Disorders - 5th edition (DSM-5). The value of p considered significant was <0.05. Ninety-five patients (51 women; 53.6%) and 50 controls (29 women; 58.0%) were assessed. Axis I PD were observed in 41 patients (43.1%). Interictal Dysphoric Disorder was observed in 18 patients (18.4%) and IP in 36 (37.9%). Interictal Dysphoric Disorder was associated with left-sided MTS (OR=3.22; p=0.008), previous psychiatric treatment (OR=4.29; p=0.007), and more than one AED used (OR=2.73; p=0.02) while presence of bilateral MTS (OR=3.27; p=0.008), longer disease duration (OR=3.39; p=0.006), and presence of Major Depressive Disorder (OR=4.73; p=0.004) were associated with IP. In the present study, there was a high prevalence of IDD and IP in patients with drug-resistant TLE-MTS; studies should be conducted to identify the presence of behavioral conditions that are not present in the conventional psychiatric classifications.

Factors predicting the outcome following surgical treatment of mesial temporal epilepsy due to mesial temporal sclerosis.

BACKGROUND: Mesial temporal sclerosis (MTS) is the most common disease found in an epilepsy surgery series. Early age of onset, a history of febrile convulsions, epileptiform discharges on EEG, duration of epilepsy, number of generalized seizures and severity of psychiatric disorders are possible prognostic factors in patients with MTS. OBJECTIVE: The aim of this study is to review the clinical, semiotic, psychological, electrophysiological and neuroradiological researches and relate their findings to the prognosis of patients with MTS who underwent anteromedial temporal lobectomy (ATL). METHODS: Of 1,214 patients evaluated for surgery in the epilepsy Center of Faculdade de Medicina de São Jose do Rio Preto (FAMERP), a tertiary Brazilian epilepsy center, 400 underwent ATL for MTS. Examinations and clinical data were analyzed and compared with the Engel Outcome Classification. RESULTS: Of all the items analyzed, the MRI showed the greatest influence on patient outcome. As for the clinical evaluation and pathological antecedents, age at surgery, epilepsy duration, perinatal insults, family history of epilepsy, febrile seizures, neuropsychological abnormalities and presence of generalized tonic-clonic seizure all had statistical significance. CONCLUSION: In order to identify the most appropriate candidates for ATL, it is very important to consider the prognostic factors associated with a favorable outcome for counseling patients in daily practice.

Longer epilepsy duration and multiple lobe involvement predict worse seizure outcomes for patients with refractory temporal lobe epilepsy associated with neurocysticercosis.

OBJECTIVE: To investigate the surgical outcomes of temporal lobe epilepsy associated with hippocampal sclerosis (TLE-HS) and neurocysticercosis (NCC). METHODS: A retrospective investigation of patients with TLE-HS was conducted in a tertiary center. RESULTS: Seventy-nine (62.2%), 37 (29.1%), 6 (4.7%), and 5 (3.9%) patients were Engel class I, II, III, and IV, respectively. Fifty-two (71.2%) patients with epilepsy durations ≤ 10 years prior to surgery were seizure-free 1 year after the operation compared to 27 (50.0%) patients with epilepsy durations > 10 years (p = 0.0121). Forty-three (72.9%) patients with three or fewer lobes affected by NCC were seizure-free one year after the operation, and 36 (52.9%) patients with more than three involved lobes were seizure-free after surgery (p = 0.0163). CONCLUSIONS: Longer epilepsy durations and multiple lobe involvement predicted worse seizure outcomes in TLE-HS plus NCC patients.

Microsurgical treatment of patients with refractory epilepsy and mesial temporal cavernous malformations: Clinical experience of a tertiary epilepsy center.

BACKGROUND: Mesiotemporal cavernous malformation can occur in 10-20% of patients with cerebral cavernomas and are frequently associated with refractory. METHODS: A retrospective investigation was performed in the epilepsy clinic of a Brazilian tertiary referral epilepsy center, from January 2000 to March 2012. RESULTS: A total of 21 patients were included in the study. Thirteen patients (62%) evolved to Engel I; 5 (24%) to Engel II, 2 (10%) to Engel III, and 1 (5%) to Engel IV. We observed that 10 (48%) patients with 12 years or less of epilepsy duration evolved to Engel I and 1 (5%) to Engel II; whereas from a total of 10 patients with epilepsy duration of more than 12 years, 3 (30%) evolved to Engel I and 7 (70%) to Engel II, III, or IV (P < 0.001 [bilateral]; P1 ≠ P2). CONCLUSION: Postsurgical seizure outcome for temporal lobe epilepsy associated with mesiotemporal cavernomas is very satisfactory.

Psychiatric disorders as "hidden" contraindications for presurgical VEEG in patients with refractory epilepsy: A retrospective cohort study in a tertiary center.

Given the high frequency of psychiatric disorders (PDs) observed among patients with epilepsy, studies have highlighted the necessity of psychiatric evaluation for these patients, especially for those with refractory temporal lobe epilepsy with mesial temporal sclerosis (TLE-MTS) who are surgical candidates. Current evidence highlights the safety of video-electroencephalography (VEEG) as a means of investigation in patients with TLE-MTS and PDs. However, the presence of such disorders has still been seen as a contraindication for presurgical evaluation with VEEG in some epilepsy centers mainly because of the risk of negative behavioral events. The present retrospective cohort study performed in a Brazilian tertiary epilepsy center aimed to identify whether the presence of a PD remains a contraindication for presurgical VEEG. Clinical, sociodemographic, and psychiatric data from 41 patients who underwent VEEG as part of their presurgical evaluation were compared to data from 32 patients with refractory TLE-MTS who had not undergone VEEG. Psychiatric diagnoses were determined using the DSM-IV and ILAE criteria. Psychiatric disorders were diagnosed in 34 patients (46.6%). Major depressive disorder was the most frequent PD and was observed in 22 patients (30.1%). Anxiety disorders were observed in 14 patients (19.2%). Of the 41 patients (56.2%) who underwent presurgical VEEG, only 12 (29.2%) were found to have a PD during the presurgical psychiatric evaluation compared to 22 of the 32 (68.7%) who did not undergo VEEG (p=0.001; RR=2.35). The present findings suggest that the presence of a PD alone should not be a contraindication for VEEG monitoring and epilepsy surgery.

Shorter epilepsy duration is associated with better seizure outcome in temporal lobe epilepsy surgery.

OBJECTIVE: To investigate the influence of patient's age and seizure onset on surgical outcome of temporal lobe epilepsy (TLE). METHOD: A retrospective observational investigation performed from a cohort of patients from 2000 to 2012. RESULTS: A total of 229 patients were included. One-hundred and eleven of 179 patients (62%) were classified as Engel I in the group with < 50 years old, whereas 33 of 50 (66%) in the group with ≥ 50 years old group (p = 0.82). From those Engel I, 88 (61%) reported epilepsy duration inferior to 10 years and 56 (39%) superior to 10 years (p < 0.01). From the total of patients not seizure free, 36 (42%) reported epilepsy duration inferior to 10 years and 49 (58%) superior to 10 years (p < 0.01). CONCLUSION: Patients with shorter duration of epilepsy before surgery had better postoperative seizure control than patients with longer duration of seizures.

Costs of epilepsy: an experience based on a specialized center

An epileptic disorder is defined as an intermittent disturbance of the nervous system and it occurs because of an excessive, sudden and disordered discharge of cerebral neurons. Lately, the cost of medical treatments, in general and in particular of the epileptic drugs, has been discusses in many countries. The objective is to evaluate the cost of epilepsy in Brazil. There were selected 87 patients with a diagnosis of epilepsy, 48 male patients and 39 female patients, with average general age of 38.5 years old. The total cost for an annual treatment of all the 87 patients was of R$62.462,45. The costs with computerized tomography of the cranium, encephalic magnetic resonance, annual electroencephalogram, annual laboratorial exams and medical consultations, was of R$8.477,28, R$3.493,75, R$986,58, R$5.649,78, R$ 3.480, respectively, with a total of R$84.549,84. The indirect costs could not be summed up because of the difficulty in obtaining retrospective information.

Qualidade de vida e desempenho ocupacional de pacientes submetidos à cirurgia de epilepsia / Quality of life and occupational performance of patients subjected to epilepsy surgery

OBJETIVO: este estudo teve como objetivo comparar a qualidade de vida e as áreas do desempenho ocupacional de pacientes epilépticos antes e doze meses após tratamento cirúrgico. METODOLOGIA: a amostra foi composta por 30 pacientes epilépticos que frequentavam o Centro de Cirurgia de Epilepsia da Faculdade de Medicina de São José do Rio Preto - FAMERP. Todos os participantes responderam a uma entrevista semiestruturada para coleta de dados sociodemográficos, ao Questionário de Qualidade de Vida em Epilepsia - 31 (QOLIE-31) e à Medida Canadense de Desempenho Ocupacional - MCDO. RESULTADOS: dezenove pacientes(63,3 por cento) eram do sexo feminino e onze (36,7 por cento) do sexo masculino, com idade entre 22 e 65 anos (42,1±11,9). Os resultados obtidos com o QOLIE-31 apontaram diferenças significativas em seis dos sete domínios que compõe o questionário quando comparados o período pré e pós-cirúrgico. A comparação dos resultados da COPM mostrou aumento significativo tanto na performance quanto na satisfação dos pacientes com suas atividades de vida diária, instrumentais de vida diária e de lazer. CONCLUSÃO: o tratamento cirúrgico se mostrou eficaz na melhora da qualidade de vida e no desempenho ocupacional o que pode traduzir-se a médio e longo prazo em integração social mais adequada para os pacientes epilépticos.

PURPOSE: this study aimed to compare the quality of life and areas of occupational performance in epileptic patients before and twelve months after surgery. METHODS: the sample consisted of 30 epileptic patients from the Centro de Cirurgia de Epilepsia da Faculdade de Medicina de São José do Rio Preto - FAMERP. All participants responded to a semi-structured interview to collect socio-demographic data, the Questionnaire Quality of Life in Epilepsy - 31 (QOLIE-31) and the Canadian Occupational Performance Measure - COPM. RESULTS: nineteen patients (63.3 percent) were female and eleven (36.7 percent) males, aged between 22 and 65 years (42.1±11.9). The results obtained with the QOLIE-31 showed significant differences in six of the seven areas that composed the questionnaire when compared to pre-and post-surgical period. The comparison of the results of COPM shows significant increase both in performance and in patients' satisfaction with their activities of daily living, instrumental in daily life and leisure. CONCLUSION: the surgical treatment is effective in improving the quality of life and occupational performance in what could be the medium and long-term social integration most appropriate for epileptic patients.

[Prolonged vídeo-EEG monitoring in nonepileptic seizures: clinical semiology]. / Monitorização vídeo-EEG prolongada em crises não epilépticas: semiologia clínica.

The purpose of this study was to point out the effectiveness of prolonged video EEG monitoring (PVEM) in the diagnosis of nonepileptic seizures (NES) as well as to estimate its prevalence in a reference center of epilepsy (EP). A sample of 47 patients with the diagnosis of NES with spontaneous or provoked seizures was observed. A protocol with the clinical history and semiology of seizures was analyzed; Fisher's exact test and cluster analysis were used for statistical observation. The results showed a prevalence of 10% of NES; more prevalence in females (63.8%); the crises were spontaneous in 57% of the patients. The mean age was 32.5 +/- 11 years and the most frequent semiological sign was apparent sleep (82.2%). Either EP or NES was observed in 9% of the patients. There were three groups according to the cluster analysis: hypermotor NES of the extremities with tonus alteration; NES with automatism; and axial NES with eye movements. In conclusion, the study of clinical semiology of NES during the PVEM provides both this nosological entity and the differential EP diagnoses while the provocative test helps to obtain the seizures.

Monitorização vídeo-EEG prolongada em crises não epilépticas: semiologia clínica / Prolonged vídeo-EEG monitoring in nonepileptic seizures: clinical semiology

O objetivo deste estudo foi mostrar a contribuição da monitorização vídeo-EEG prolongada (MVEP) no diagnóstico de crises não epilépticas (CNE) e estimar sua prevalência em um centro terciário de atendimento à Epilepsia (EP). Foram observados 47 pacientes com diagnóstico de CNE com crises espontâneas ou provocadas. Foram instituídos protocolos direcionados à história clínica e à semiologia das crises. A análise estatística baseou-se no teste de Fisher e na análise de cluster. Os resultados evidenciaram prevalência de 10 por cento de CNE. Houve predominância do sexo feminino (63,8 por cento); em 57 por cento dos pacientes as crises foram espontâneas. A média de idade foi 32,5 ± 11anos. O sinal semiológico mais freqüente foi o sono aparente (87,2 por cento). Em 9 por cento dos pacientes observaram-se tanto EP como CNE. Três agrupamentos resultaram da análise de cluster: CNE hipermotora das extremidades com alteração de tônus; CNE com automatismos e CNE axial com movimentos oculares. Em conclusão, o estudo da semiologia clínica das CNE durante a MVEP contribui para o diagnóstico desta entidade nosológica e para o diagnóstico diferencial com EP; o teste provocativo auxilia na obtenção das crises.
