From 95,196 sample adults in the combined 2010, 2013, and 2015 U.S. National Health Interview Survey, we estimated the association between histories of epilepsy and heart disease after accounting for sociodemographic characteristics and behavioral risk factors. Adults 18 years old or older with an epilepsy history reported heart disease (21%) about nine percentage points more often than those without such a history (12%), overall and within levels of characteristics and risk factors. These increases in heart disease history for adults with an epilepsy history compared with adults without such a history were greater in those 45-64 years old or at the lowest family income levels. These increases of heart disease in adults with an epilepsy history highlight two needs-to prevent the occurrence of heart disease and to reduce its consequences. Because comorbidity from heart disease can complicate epilepsy management, physicians caring for those with epilepsy should be aware of these increased risks, identify risk factors for heart disease, and recommend to their patients with epilepsy ways to diminish these risks.

Navigated transcranial magnetic stimulation (nTMS) is becoming increasingly popular in noninvasive preoperative language mapping, as its results correlate well enough with those obtained by direct cortical stimulation (DCS) during awake surgery in adult patients with tumor. Reports in the context of epilepsy surgery or extraoperative DCS in adults are, however, sparse, and validation of nTMS with DCS in children is lacking. Furthermore, little is known about the risk of inducing epileptic seizures with nTMS in pediatric epilepsy patients. We provide the largest validation study to date in an epilepsy surgery population. We compared language mapping with nTMS and extraoperative DCS in 20 epilepsy surgery patients (age range 9-32 years; 14 children and adolescents). In comparison with DCS, sensitivity of nTMS was 68%, specificity 76%, positive predictive value 27%, and negative predictive value 95%. Age, location of ictal-onset zone near or within DCS-mapped language areas or severity of cognitive deficits had no significant effect on these values. None of our patients had seizures during nTMS. Our study suggests that nTMS language mapping is clinically useful and safe in epilepsy surgery patients, including school-aged children and patients with extensive cognitive dysfunction. Similar to in tumor surgery, mapping results in the frontal region are most reliable. False negative findings may be slightly more likely in epilepsy than in tumor surgery patients. Mapping results should always be verified by other methods in individual patients.

As well as being a very common neurological disease worldwide, epilepsy significantly impairs patients' emotional, behavioral, and cognitive functioning. Sleep disturbances are the most frequent complaint in patients with epilepsy. The present study assesses the impact of a range of affective symptoms on subjective sleep quality and sleep disturbances in Chinese adults with epilepsy. Adults with epilepsy who visited our epilepsy clinic from July 2015 to March 2016 were enrolled in our study. Both patients and healthy controls completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and Mini-mental State Examination (MMSE). Subjective sleep quality and sleep disturbances were examined with regard to self-reported symptoms of depression and anxiety, seizure-related factors, and demographic factors. The PSQI scores and ISI scores of patients were significantly higher (indicating lower quality sleep and more serious insomnia) than those of the control group. Symptoms associated with depression and anxiety were independently related to impaired subjective sleep quality and insomnia. Affective symptoms explained more of the variance in PSQI scores and ISI scores than did seizure-related or demographic variables. In addition, these variables also seemed to be less powerful contributing factors to subjective sleep quality and insomnia than affective symptoms, several seizure-related factors, such as seizure control, partial seizures and duration of epilepsy, which are also significantly associated with subjective sleep quality and insomnia. In addition, use of lamotrigine (LTG) was also associated with insomnia and use of clonazepam (CZP) and phenobarbital (PB) with daytime sleepiness in patients with epilepsy. Chinese adults with epilepsy have poorer self-reported subjective sleep quality and a higher prevalence of insomnia than the control group

Seizure precipitants (triggering factors) in patients with epilepsy.

adult epilepsy clinic population: (a) to identify the frequency of seizure precipitants (triggering factors) and their relative frequency in those with psychiatric disorders, and in those in remission or with active epilepsy, differences in frequency with regard to gender, seizure duration, number of drugs taken; (b) to determine which precipitants patients most commonly report; and (c) to identify differences in the distribution of precipitants among generalized, temporal, and extratemporal epilepsies. Consecutive patients attending a tertiary-care epilepsy clinic were prospectively and an open personal interview to identify and characterize seizure precipitants. Information about the epilepsy and clinical characteristics of patients was collected during the interview and from medical records. Of 104 patients, 97% cited at least one precipitant. Stress, sleep deprivation, and fatigue were the most frequently reported precipitants. Patients with psychological comorbidities reported a greater percentage of seizures with seizure precipitants. Patients with idiopathic generalized epilepsy seemed to be more sensitive to seizures during awakening and sleep deprivation, patients with extratemporal epilepsy reported more frequent seizures during sleep. There were no differences in frequency or type of seizure precipitants with regard to gender, seizure duration or frequency, and the number of antiepileptic drugs taken. The findings may have implications for the better management of epilepsy by increasing a focus on nonpharmacological therapy. The implications of the findings for nosology and causation of epilepsy are also briefly discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

Epilepsy is common in people with intellectual and developmental disabilities (IDD). In adulthood, patients with IDD and epilepsy (IDD-E) have neurologic, psychiatric, medical, and social challenges compounded by fragmented and limited care. With increasing neurologic disability, there is a higher frequency of epilepsy, especially symptomatic generalized and treatment-resistant epilepsies. The causes of IDD-E are increasingly recognized to be genetic based on chromosomal microarray analysis to identify copy number variants, gene panels (epilepsy, autism spectrum disorder, intellectual disability), and whole-exome sequencing. A specific genetic diagnosis may guide care by pointing to comorbid disorders and best therapy. Therapy to control seizures should be individualized, with drug selection based on seizure types, epilepsy syndrome, concomitant medications, and comorbid disorders. There are limited comparative antiepileptic drug data in the IDD-E population. Vagus nerve and responsive neural stimulation therapies and resective surgery should be considered. Among the many comorbid disorders that affect patients with IDD-E, psychiatric and sleep disorders are common but often unrecognized and typically not treated. Transition from holistic and coordinated pediatric to adult care is often a vulnerable period. Communication among adult health care providers is complex but essential to ensure best care when these patients are seen in outpatient, emergency room, and inpatient settings. We propose specific recommendations for minimum care standards for people with IDD-E. PMID:26423430

The experience of living with adult-onset epilepsy.

2017-08-01

The incidence and prevalence of adults diagnosed with epilepsy is higher compared to those diagnosed in childhood, yet the experience of living with adult-onset epilepsy has rarely been examined. Hence, the current study took a phenomenological approach to examining the experience of living with epilepsy following diagnosis in adulthood. Semi-structured interviews were conducted with 39 people from across the UK, diagnosed with epilepsy between the ages of eighteen and sixty, at two points in time, six months apart. Phenomenological analysis identified three central themes: the unpredictability of seizure occurrence; the ripple effect; and re-evaluating the future. Despite the accepted consensus in the epilepsy literature that living and coping with epilepsy becomes more difficult the older a person is diagnosed, the current findings indicated that this is inadequate. Rather, it is more suitable to consider that those living with adult-onset epilepsy have a specific experience of the condition and particular support needs, given that they once lived their lives as people without epilepsy.

The ketogenic diet (KD) is an effective treatment for children with drug-resistant epilepsy and has been widely used in young children. Adult patients with intractable epilepsy would also benefit from this dietary treatment. However, only a few studies have been published, and the use of the KD in intractable epilepsy in adults has been limited. This meta-analysis summarized the findings of the relevant published studies to identify the efficacy of the KD for the treatment of intractable epilepsy in adults. In this meta-analysis, PubMed, Embase, and Cochrane Library were used for searching studies concerning the effects of the KD and its major subtypes with intractable epilepsy in adults published up to January 10, 2017. The primary outcomes were seizure freedom, seizure reduction by 50% or more, and seizure reduction by <50%. The quality of the methodology of the observational studies was reviewed by using the Newcastle-Ottawa Scale. We identified 402 articles, of which, 16 studies including 338 patients met the inclusion criteria. The results of the meta-analysis showed that the combined efficacy rates of all the symptoms of seizure freedom, seizure reduction by 50% or more, and seizure reduction below 50% in adults with intractable epilepsy were 13%, 53%, and 27%, respectively. The adverse reactions of the KD were mild, whereas low glycemic index diet (LGID) and low-dose fish oil diet (LFOD) may have fewer side effects. Weight loss, high level of low-density lipoprotein, and elevated total cholesterol were most frequent. The meta-analysis indicates that the KD for refractory epilepsy in adults is a well-tolerated treatment and that its side effects are acceptable, which show that the KD is a promising treatment in adult intractable epilepsy. Further research is needed to assess which type of diet or ratio is more effective in the KD treatment.

Objective Assess accuracy and operating characteristics of the Patient Health Questionnaire-9 (PHQ-9) for depression-screening in adults with epilepsy. Methods Tertiary epilepsy center patients served as the study population with 237 agreeing to structured interview using the Mini-International Neuropsychiatric Interview (MINI), a “gold standard” instrument developed for rapid diagnosis of neuropsychiatric disorders, including major depressive disorder (MDD); 172 also completed the PHQ-9, and 127 completed both the PHQ-9 and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) within two days of the MINI. Sensitivity, specificity, positive & negative predictive values & areas under the ROC curves for each instrument were determined. Cut-points of 10 for the PHQ-9 and 15 for the NDDI-E were used and ratings at or above the cut-points were considered screen-positive. The PHQ-9 was divided into cognitive/affective (PHQ-9/CA) and somatic (PHQ-9/S) subscales to determine comparative depression-screening accuracy. Results The calculated areas under the ROC curves for the PHQ-9 (n=172) and the PHQ-9/CA and PHQ-9/S sub-scales were 0.914, 0.924, and 0.846, respectively, with the PHQ-9 more accurate than the PHQ-9/S (p=0.002) but no different than the PHQ-9/CA (p=0.378). At cut-points of 10 and 15, respectively, the PHQ-9 had higher sensitivity (0.92 vs 0.87), but lower specificity (0.74 vs 0.89) than the NDDI-E. The areas under the ROC curves of the PHQ-9 and the NDDI-E showed similar accuracy (n=127; 0.930 vs 0.934; p=0.864). Significance The PHQ-9 is an efficient & non-proprietary depression screening instrument with excellent accuracy validated for use in adult epilepsy patients as well as multiple other medical populations.

To describe the adult population treated with antiepileptic drugs (AEDs) in combination for focal epilepsy according to the definition of AED resistance proposed by the International League Against Epilepsy (ILAE) in 2009 and to evaluate its implementation in current practice. ESPERA was a multicenter, observational, cross-sectional study with a clinical data collection covering the past 12 months conducted by neurologists. Classifications according to AED responsiveness established by investigators for each enrolled patient were revised by two experts. Seventy-one neurologists enrolled 405 patients. Their mean age was 42.7 years (sex-ratioM/F 0.98). According to the investigators, 60% of epilepsies were drug-resistant, 37% drug-responsive and 3% had an undefined drug-responsiveness. After revision of experts, 71% of epilepsies were classified as drug resistant, 22% as responsive and 7% as undefined. Among the participating neurologists, 76% have made at least one error in classifying their patients according to the 2009 ILAE definition of AED resistance. Because of epilepsy, 24% of patients (age≤65) were inactive and 42% could not drive (respectively 29 and 49% of patients with AED resistant epilepsy). Half of patients had at least one other chronic condition. Number of prescribed drugs in combination and health care resource utilisation were significantly higher in patients with drug-resistant epilepsies than in patients with drug responsive epilepsies. ESPERA study shows that the use of new definition of drug-resistance in everyday practice seems difficult without any additional training and that the social and professional disability is frequent in adults with focal epilepsies treated with polytherapy.

Living Well with Epilepsy II called for further attention to stigma and its impact on people with epilepsy. In response, the South Carolina Health Outcomes Project on Epilepsy (SC HOPE) is examining the relationship between socioeconomic status, epilepsy severity, health care utilization, and quality of life in persons diagnosed with epilepsy. The current analysis quantifies perceived stigma reported by adults with epilepsy in relation to demographic, seizure-related, health, and psychosocial factors. It was found that reported levels of stigma were associated with interactions of seizure worry and employment status, self-efficacy and social support, and quality care and age at seizure onset. This information may be used to target and develop evidence-based interventions for adults with epilepsy at high risk for perceived stigma, as well as to inform epilepsy research in self-management.

Public awareness, knowledge, and practice relating to epilepsy among adults in Konya.

This study aimed to determine the familiarity with, knowledge of, misunderstandings, and attitudes toward epilepsy among a group of Turkish adults living in Konya, an urban city in central Turkey. By using an established familiarity-knowledge-attitudes practice questionnaire, 500 randomly selected adult residents of Konya were interviewed face-to-face. Demographic and sociocultural factors that predicted negative attitudes were determined. More than half of all participants (68.4%) reported hearing or reading about epilepsy, 44% knew someone with epilepsy, and 42.2% had witnessed a seizure. The primary source of knowledge was via relatives and friends; Negative attitudes were about marriage and inability to live alone with epilepsy (63.2% objected to marriage and 84% objected to living alone). A preconception of epilepsy being a dangerous and lifelong disease was the primary reason for negative attitudes. Predictors of negative attitudes were female gender, lower educational status, and living in a rural area. Negative attitudes regarding the marital status of patients with epilepsy still exist. These may stem from misconceptions about the cause and treatability of epilepsy. Copyright © 2016 Elsevier Inc. All rights reserved.

Neurodevelopmental and behavioral health disorders commonly occur with epilepsy, yet risk for young adults is unknown. The aim of this study was to determine the distribution and risk characteristics of neurodevelopmental and behavior health comorbidities among young adults with epilepsy compared with those among young adults with migraine and healthy controls. A case-control study examining hospital admission, outpatient, and emergency department (ED) visits for young adults with an ICD-9-CM diagnosis of epilepsy, migraine, or lower extremity fracture (LEF) was conducted. The association of epilepsy, migraine, or LEF with comorbidities was evaluated with univariate and multivariate polytomous logistic regression. From 2000 to 2013, 29,139 young adults ages 19 to 25years were seen in hospitals and EDs for epilepsy (5666), migraine (17,507), or LEF (5966). Young adults with epilepsy had higher proportions of behavioral health comorbidities (51.8%) compared with controls with migraine (37.6%) or LEF (21.6%). In young adults with epilepsy compared with migraine, the increased risk of having any behavioral health comorbidity was 76%, and neurodevelopmental comorbidity was 297%. After adjustment, young adults with epilepsy showed significantly higher odds of each behavioral health comorbidity compared with controls with migraine and LEF. Young adults with epilepsy are particularly susceptible to behavioral health and neurodevelopmental disorders. Results are discussed within the context of transition to adult care.

Interpersonal relationships are viewed as important contexts within which psychopathology emerges and persists or desists. Attachment theory describes the dynamics of long-term relationships between humans especially in families and lifelong friendships. The present study was aimed at investigating attachment styles in adult patients with epilepsy as compared to subjects with migraine and their potential correlates with a history of mood disorders. A consecutive sample of 219 adult outpatients with epilepsy (117) or migraine (102) was assessed with the Attachment Style Questionnaire (ASQ). Patients with epilepsy and a lifetime history of mood disorders presented elevated scores for Need for approval (p<0.001) and Preoccupation with relationships (p<0.001). Age correlated with the Relationships as secondary (r=0.322; p<0.001) and Need for approval (r=0.217; p=0.019) subscales while age at onset correlated only with Relationships as secondary (r=0.225; p=0.015). Seizure-free patients presented lower scores for Need for approval (p=0.003). Patients with migraine and a lifetime history of mood disorders presented lower scores in Confidence (p=0.002) and higher scores in Discomfort with closeness (p=0.026). An anxious-preoccupied attachment correlated with mood disorders in epilepsy while it was an avoidant pattern in migraine. Our results bring further data on the role of psychological variables in mood disorders in epilepsy. Further studies will allow early identification of patients at risk and the development of preventive strategies. Copyright © 2015 Elsevier Inc. All rights reserved.

Epilepsies are neurological disorders with many different etiologies, symptoms and prognoses. Care for epilepsy patients should be uniform, homogeneous and optimized to avoid unnecessary hospitalizations or even worse outcomes. FinCC-based structured nursing documentation facilitates analyzing patient profiles and populations, developing care processes, nursing documentation, decision-making, and data reuse. This research aimed to determine the potential for finding possible risks for epilepsy patients' health and well-being from the structured nursing data with defined triggers for epilepsy patients. The research data included structured documentation of nursing diagnoses of and interventions for adult epilepsy patients (n = 100) at one neurological ward in a university hospital in 2009-2013. The results showed that nurses documented abundantly, and all triggers were mostly found. The study results will be reviewed by the neurological ward nurses to assess the FinCC and highlight the importance of documentation.

Sleep disorders in adults with epilepsy: past, present, and future directions.

PubMed

Grigg-Damberger, Madeleine M; Ralls, Frank

2014-11-01

To summarize recent studies on the complex relationships between sleep disorders, sleep, and epilepsy. Insomnia in adults with epilepsy (AWE) warrants consideration of depression, anxiety, and suicidal ideation. Daytime sleepiness in AWE is more often due to undiagnosed sleep disorders. Sleep deprivation is an important provoker of seizures in juvenile myoclonic epilepsy. Abnormalities in frontal lobe executive function with difficulties making advantageous decisions may explain failure of juvenile myoclonic epilepsy patients to adhere to treatment recommendations and regulate their sleep habits. Sleep architecture in AWE is more likely to be abnormal if seizures are poorly controlled or occur during sleep. Obstructive sleep apnea is much more common in AWE who are man, older, heavier, or whose seizures are poorly controlled. Chronobiology and chronopharmacology of epilepsy is an emerging field worthy of future research and clinical applications. Identifying and treating unrecognized sleep disorders and understanding the impact of circadian rhythms on epilepsy can improve quality of life and seizure control in AWE.

A few studies have explored dissociative experiences in epilepsy patients. We investigated dissociative experiences in patients with epilepsy using the dissociative experiences scale (DES). Ninety-eight patients with epilepsy and sixty healthy controls were enrolled in this study. A sociodemographic questionnaire and the Dissociative Experiences Scale (DES), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were administered to the participants. The DES scores were significantly higher for the patients with epilepsy than the healthy individuals. The number of individuals with pathological dissociation (DES ≥ 30) was higher in the epilepsy group (n = 28) than in the control group (n = 8). Also, higher levels of dissociation were significantly associated with frequency of seizures, but were not associated with duration of epilepsy and age at onset of the disorder. These findings demonstrate that patients with epilepsy are more prone to dissociation than controls. The high rate of dissociative experiences among patients with epilepsy suggest that some epilepsy-related factors are present.

Studies using relative measures, such as standardized mortality ratios, have shown that patients with epilepsy have an increased mortality. Reports on more direct and absolute measure such as life expectancy are sparse. We report potential years lost and how life expectancy has changed over 40 years in a cohort of patients with newly diagnosed epilepsy. We analyzed life expectancy in a cohort of adult patients diagnosed with definite epilepsy between 1970 and 2010. Those with brain tumor as cause of epilepsy were excluded. By retrospective probabilistic record linkage, living or death status was derived from the national death registry. We estimated life expectancy by a Weibull regression model using gender, age at diagnosis, epilepsy etiology, and year of diagnosis as covariates at time of epilepsy diagnosis, and 5, 10, 15, and 20 years after diagnosis. Results were compared to the general population, and 95% confidence intervals are given. There were 249 deaths (105 women, age at death 19.0-104.0 years) in 1,112 patients (11,978.4 person-years, 474 women, 638 men). A substantial decrease in life expectancy was observed for only a few subgroups, strongly depending on epilepsy etiology and time of diagnosis: time of life lost was highest in patients with symptomatic epilepsy diagnosed between 1970 and 1980; the impact declined with increasing time from diagnosis. Over half of the analyzed subgroups did not differ significantly from the general population. This effect was reversed in the later decades, and life expectancy was prolonged in some subgroups, reaching a maximum in those with newly diagnosed idiopathic and cryptogenic epilepsy between 2001 and 2010. Life expectancy is reduced in symptomatic epilepsies. However, in other subgroups, a prolonged life expectancy was found, which has not been reported previously. Reasons may be manifold and call for further study. © 2017 The Authors. Epilepsia published by Wiley Periodicals, Inc. on behalf of International

[The efficacy of lacosamide in relation to antiepileptic drug history. Clinical experiences in adult partial epilepsy].

2015-01-30

A retrospective study in adult partial epilepsy on the efficacy of lacosamide in relation to previous antiepileptic drug experiences. We analysed 3-65 months' data on epilepsy-care of 43 pharmacoresistant partial epilepsy patients treated with lacosamide. Further analysis of antiepileptic drug history was carried out in strictly selected subgroups of patients with good and poor therapeutic response to lacosamide (10 and 9 patients, respectively) for 2-10 years long retrospective follow up. Adult patients with partial-onset seizures had been treated previously with three or more lifetime antiepileptic drugs without permanent success. Six patients (14%) were seizure free, eleven patients (25%) have experienced important improvement (their seizure-frequency decreased by at least 50%) for more than 12 months. Fourteen patients (32%) improved for less than 6 months and then have relapsed; and add-on lacosamide proved ineffective in 12 patients (28%). Those selected 10 patients successfully treated with lacosamide (seizure free for at least six months) favourably responded to carbamazepine or oxcarbazepine earlier and levetiracetam was ineffective or even caused worsening. The selected lacosamide-unresponsive nine patients responded unfavourably to carbamazepine or oxcarbazepine earlier. Fifteen patients (35%) suffered side effects as dizziness or sleepiness, in 11 of them lacosamide was combined with a "traditional" sodium-channal blocker antiepileptic drug. Lacosamide is an effective add-on antiepileptic drug in difficult-to treat adult partial epilepsy patients. Our data suggest that good lacosamide response may be expected in those patients who reacted favourably to "traditional" sodium-channel blocker carbamazepine or oxcarbazepine earlier.

Objectives: Epilepsy is a common neurological disorder with a median lifetime prevalence of 14 per 1000 subjects. Sleep disorders could influence epileptic seizure. The most common sleep disorder is obstructive sleep apnea syndrome (OSAS) which occurs in 2% of adult women and 4% of adult men in the general population. The aim of this study is to estimate the frequency of OSAS among patients with epilepsy and to study the seizure characteristics among those patients with co-morbid OSAS. Methods: Patients with a confirmed diagnosis of epilepsy who attended the Sultan Qaboos University Hospital neurology clinic were recruited for the study between June 2011 and April 2012. Patients were screened for OSAS by direct interview using the validated Arabic version of the Berlin questionnaire. Patients identified as high-risk underwent polysomnography. Results: A total of 100 patients with epilepsy (55 men and 45 women) were screened for OSAS. Generalized and focal seizure was found in 67% of male and 27% of female patients. Six percent of the participants had epilepsy of undetermined type. Only 9% of the sample was found to have high risk of OSAS based on the Berlin questionnaire. No significant correlation was found between risk of OSAS, type of epilepsy, and anti-epileptic drugs. Conclusion: The risk of OSAS was marginally greater in patients with epilepsy compared to the general population with the overall prevalence of 9%.

The attitude of patients with epilepsy towards their disease is an important factor in disease management and quality of life. The aim of this study was to define the attitudes of patients with epilepsy towards their disease and the factors that affect their attitudes. This descriptive study was performed on patients admitted to an epilepsy outpatient clinic of a university hospital between May and September 2015. The sample consisted of 70 patients over 18years of age with a diagnosis of epilepsy and no health problem other than epilepsy. Patients with no seizure in the last two years were excluded. The Epilepsy Attitude Scale was used to evaluate attitudes of the patients towards epilepsy; the Epilepsy Knowledge Scale, Rotter's Locus of Control Scale, Hospital Anxiety and Depression Scale (HADS), and the Quality of Life in Epilepsy-10 (QOLIE-10) were used to investigate the attitude-related factors. Among the 70 participants, 43 were female, and the mean age was 31.4years. The educational level of the patients was lower (primary school) in 38.6% of the sample, and 18.6% were unemployed. Time since diagnosis was 15.1years, 75.7% of the participants had generalized type of seizures, and more than half had seizures more frequently than once a month. The mean score of the attitude scale was 59.7±6.62 (range: 14-70). The attitudes of the patients towards epilepsy were found to be related to their educational status, living alone, and the attitudes of their families. The attitude scores were also related to the level of knowledge on epilepsy, stigma, and depression. Furthermore, the attitude was found to be correlated with quality of life. Patients with epilepsy had moderate-to-good attitude towards their disease. It was observed that the attitude was related to the knowledge, stigma, and depression rather than to demographic factors and the seizures, and furthermore, the attitude was found to be correlated with quality of life.

The first step to increasing access to epilepsy surgery is to provide access to evidence-based care for all patients with epilepsy, both adults and children, through the provision of resources to expand EMU bed capacity and associated clinical personnel across the province of Ontario. Plain Language Summary Epilepsy, characterized by recurrent, unpredictable, and spontaneous seizures, affects approximately 70,000 people in Ontario. About 30% continue to suffer from seizures despite using 2 or more anti-seizure medications. For these individuals epilepsy surgery is a treatment option to stop the seizures or at least reduce their frequency. Awareness of this treatment option is not widespread and people are not commonly referred to those hospitals in Ontario where this surgery is available. A proposal to increase access to epilepsy care and surgery has been made by an expert committee that provided a report to the Ontario Health Technology Advisory Committee (OHTAC). In order to address the lack of access of patients with medically intractable epilepsy to the possibility of curative surgical treatment, it is necessary to design a system that provides equal availability of evidence-based treatment for all epilepsy patients in Ontario, both adults and children. To this end, the establishment of district epilepsy care centres and the further development of the existing regional epilepsy care centres in the province have been proposed. This report outlines the estimated additional funds that will be required to implement the proposal. It also examines the cost-effectiveness of referral to these centres and epilepsy surgery. For the 21,000 people in the province with drug-refractory epilepsy, referral to an epilepsy monitoring unit (EMU) located at one of the epilepsy care centres is the first step to determining if epilepsy surgery is an

Approximately 3 million American adults reported active epilepsy* in 2015 (1). Active epilepsy, especially when seizures are uncontrolled, poses substantial burdens because of somatic, neurologic, and mental health comorbidity; cognitive and physical dysfunction; side effects of antiseizure medications; higher injury and mortality rates; poorer quality of life; and increased financial cost (2). Thus, prompt diagnosis and seizure control (i.e., seizure-free in the 12 months preceding the survey) confers numerous clinical and social advantages to persons with active epilepsy. To obtain recent and reliable estimates of active epilepsy and seizure control status in the U.S. population, CDC analyzed aggregated data from the 2013 and the 2015 National Health Interview Surveys (NHISs). Overall, an annual estimated 2.6 million (1.1%) U.S. adults self-reported having active epilepsy, 67% of whom had seen a neurologist or an epilepsy specialist in the past year, and 90% of whom reported taking epilepsy medication. Among those taking epilepsy medication, only 44% reported having their seizures controlled. A higher prevalence of active epilepsy and poorer seizure control were associated with low family income, unemployment, and being divorced, separated, or widowed. Use of epilepsy medication was higher among adults who saw an epilepsy specialist in the past year than among those who did not. Health care and public health should ensure that adults with uncontrolled seizures have appropriate care and self-management support in order to promote seizure control, improve health and social outcomes, and reduce health care costs.

We aimed to evaluate the clinical value of gamma oscillations in MEG for intractable neocortical epilepsy patients with cortical dysplasia by comparing gamma and interictal spike events. A retrospective analysis of MEG recordings of 30 adult neocortical epilepsy patients was performed. Gamma (30–70 Hz) and interictal spike events were independently identified, their independent or concurrent presence determined, and their source localization rates compared. Of 30 patients, gamma activities were detected in 28 patients and interictal spikes in 24 patients. Gamma events alone appeared in 5 patients, interictal spikes alone in 1 patient, and no events in 1 patient. Gamma co-occurred with interictal spikes in 20.1 ± 22.1% and interictal spikes co-occurred with gamma in 15.0 ± 19.2%. Rates of event localization within the resection cavity were significantly different (p = 0.042) between gamma (63.3 ± 32.6%) and interictal spike (47.0 ± 41.3%) events. In 4 of the 5 gamma-only patients the mean localization rate was 42.5%. Compared with the interictal spike localization rate, 4 of 9 seizure-free patients had higher gamma localization rates, 4 had the same rate, and 1 had a lower rate. Individual gamma events can be detected independently from interictal spike presence. Gamma can be localized to the resection cavity at least comparably to or more frequently than that from interictal spikes. Even when interictal spikes were undetected, gamma sources were localized to the resection cavity. Gamma oscillations may be a useful indicator of epileptogenic focus. PMID:24273733

Adjunctive antiepileptic drugs in adult epilepsy: how the first add-on could be the last.

PubMed

Cretin, Benjamin; Hirsch, Edouard

2010-05-01

In adult epilepsies, incomplete seizure control under monotherapy affects approximately 20-25% of patients with idiopathic generalized epilepsies (IGE) and approximately 20-40% of patients with epilepsies with focal seizures (FE). The choice of an adjunctive therapy is therefore a common event. Efficacy studies of add-on anti-epileptic drugs for adult epilepsies--approved since the early 1990s until 2008--were reviewed. An exception was made for valproate. Efficacy studies give important clues for add-on drug choice but--beyond this--we encourage physicians to consider other parameters, especially co-morbidity(ies) and special situation(s). According to clinical and pharmacological data, an original, practical approach is proposed, by which decisions are based on three main criteria, which aim to optimize patients' seizure control and quality of life. The need for drugs that act not only on 'ictogenesis' but also on 'epileptogenesis' is also discussed briefly. Given the increasing disposal of anti-epileptic drugs, the choice of an add-on therapy appears to be partly based on subjective criteria (physician opinions and preferences). In fact, the selection criteria can be clarified as: treatment decisions rely not only on seizure type, efficacy and tolerability profiles but also on patient-related factors.

Objective To evaluate and compare long-term effectiveness of five antiepileptic drugs (AEDs) for monotherapy of adult patients with focal epilepsy in routine clinical practice. Methods Adult patients with focal epilepsy, who were prescribed with carbamazepine (CBZ), valproate (VPA), lamotrigine (LTG), topiramate (TPM), or oxcarbazepine (OXC) as monotherapy, during the period from January 2004 to June 2012 registered in Wenzhou Epilepsy Follow Up Registry Database (WEFURD), were included in the study. Prospective long-term follow-up was conducted until June 2013. The endpoints were time to treatment failure, time to seizure remission, and time to first seizure. Results This study included 654 patients: CBZ (n=125), VPA (n=151), LTG (n=135), TPM (n=76), and OXC (n=167). The retention rates of CBZ, VPA, LTG, TPM, and OXC at the third year were 36.1%, 32.4%, 57.6%, 37.9%, and 41.8%, respectively. For time to treatment failure, LTG was significantly better than CBZ and VPA (LTG vs. CBZ, hazard ratio, [HR] 0.80 [95% confidence interval: 0.67-0.96], LTG vs. VPA, 0.53 [0.37-0.74]); TPM was worse than LTG (TPM vs. LTG, 1.77 [1.15-2.74]), and OXC was better than VPA (0.86 [0.78-0.96]). After initial target doses, the seizure remission rates of CBZ, VPA, LTG, TPM, and OXC were 63.0%, 77.0%, 83.6%, 67.9%, and 75.3%, respectively. LTG was significantly better than CBZ (1.44 [1.15-1.82]) and OXC (LTG vs. OXC, 0.76 [0.63-0.93]); OXC was less effective than LTG in preventing the first seizure (1.20 [1.02-1.40]). Conclusion LTG was the best, OXC was better than VPA only, while VPA was the worst. The others were equivalent for comparisons between five AEDs regarding the long-term treatment outcomes of monotherapy for adult patients with focal epilepsy in a clinical practice. For selecting AEDs for these patients among the first-line drugs, LTG is an appropriate first choice; others are reservation in the first-line but VPA is not. PMID:26147937

The understanding of causation of epilepsy, especially in resource poor African countries where prevalence rates are very high, would aid strategies for primary prevention. This study sought to determine the causes of epilepsy in Nigerian Africans and health-itinerary of patients with epilepsy. This was an observational, cross-sectional descriptive study of consecutive newly diagnosed adult patients with epilepsy using a mixed-methods approach of face-to-face in-depth interview of patients' parents and relations, health care personnel who had given medical attention at any time and telephone interview. A structured interview schedule was used to obtain demographic information, details of seizure variables, health seeking itinerary and history of previous hospitalizations. Data was analyzed descriptively with SPSS version 17. Three hundred and forty-two patients with epilepsy with a mean age of 31.4±11.98 years participated in the study. Most of the patients (68.1%; 233/342) were unemployed and students. There were 270 (78.9%) patients with generalized epilepsy. No identifiable etiology was found in 37.7%, but of the remaining 62.3%, the commonest causes included post traumatic (19.6%), recurrent childhood febrile convulsions (13.2%), post-stroke (6.7%), brain tumors (5.9%), neonatal jaundice (5.3%), birth-related asphyxia (5%) and history of previous CNS infections (4.7%). Family history of epilepsy was obtained in 9.9%, all of whom had primarily generalized seizures. 61.4% of them sought initial attention from the traditional healers or in prayer houses. This study showed the pattern of causes of epilepsy in Nigerian Africans. The health seeking behavior and itinerary of the PWE revealed a preference for traditional healers. There is need for health policies and epilepsy awareness campaigns to prevent causes of seizures and improve the knowledge of the public respectively. Copyright © 2013 British Epilepsy Association.

The purpose of this study was to assess eight factors considered important for quality of life in persons with epilepsy in order to determine which of these components affect quality of life in adults with epilepsy in Taiwan. A cross-sectional, correlational study using structured questionnaires assessed 260 patients with epilepsy purposively sampled from a medical center in Northern Taiwan. Health-related quality of life (HRQoL) was evaluated with the Quality of Life in Epilepsy-31 (QOLIE-31) questionnaire. Data also included personal and health-related characteristics, knowledge of epilepsy, efficacy in the self-management of epilepsy, and social support. Scores for the QOLIE-31 were correlated with the following factors: (1) demographic characteristics of age, gender, and income; (2) sleep quality; (3) symptoms of anxiety and depression; (4) epilepsy-specific variables: seizure frequency; types, number, and frequency of antiepileptic drugs (AEDs); and adverse events of AEDs; and (5) social support. Stepwise regression analysis showed that seven factors were predictive for quality of life: anxiety, depression, adverse events of AEDs, social support, seizure frequency of at least once in three months, household income of NT$ 40,001-100,000, and male gender. These factors accounted for 58.2% of the variance of quality of life. Our study assessed multiple factors in an examination of relationships and predictive factors for quality of life in adults with epilepsy in Taiwan. Knowledge of these contributing factors can assist health-care providers when evaluating patients with epilepsy to help target interventions for improving quality of life.

The current survey sought to identify the religious and cultural beliefs about the causes and treatment of epilepsy in people with epilepsy from Saudi Arabia and a number of other aspects relating to the possibility of cure, coping with the condition, and public awareness. Study instruments were developed on the basis of the literature, a focus group of people with epilepsy, and feedback from people in the field with local knowledge. These were then piloted. A survey was then carried out among a total of 110 adults with epilepsy. Participants were asked to complete questionnaires inquiring into their beliefs about the causes and range of treatments used for epilepsy. Each participant was allowed to choose more than one cause and more than one treatment method. The questionnaires were administered face to face by a clinical psychologist (HAA) to improve the quality of the responses. We found that most adults with epilepsy in Saudi Arabia believe that epilepsy is a condition with multifactorial causation and for which more than one treatment method should be applied. A test from God was the most commonly ascribed cause (83% as well as 40% who believed that some cases of the illness were a punishment from God). The belief in the concept of God's will helped many in the cohort to accept their illness as part of their destiny. Ninety-six percent of the patients believed that there were also medical causes (such as an illness, brain insult, inflammation, heredity, contagion), and a similar proportion believed that there were also religious causes. Smaller proportions believed epilepsy could be due to cultural (78%) or psychosocial causes (64%). Thirty-four percent of people believed that there could be sometimes no cause, but only 2% thought that epilepsy never had any identifiable cause. Most patients did not believe that one treatment alone would help. Ninety-three percent of patients believed in medical treatment, 93% in religious treatment, and 64% in traditional

Cognition and dementia in older patients with epilepsy

Abstract With advances in healthcare and an ageing population, the number of older adults with epilepsy is set to rise substantially across the world. In developed countries the highest incidence of epilepsy is already in people over 65 and, as life expectancy increases, individuals who developed epilepsy at a young age are also living longer. Recent findings show that older persons with epilepsy are more likely to suffer from cognitive dysfunction and that there might be an important bidirectional relationship between epilepsy and dementia. Thus some people with epilepsy may be at a higher risk of developing dementia, while individuals with some forms of dementia, particularly Alzheimer’s disease and vascular dementia, are at significantly higher risk of developing epilepsy. Consistent with this emerging view, epidemiological findings reveal that people with epilepsy and individuals with Alzheimer’s disease share common risk factors. Recent studies in Alzheimer’s disease and late-onset epilepsy also suggest common pathological links mediated by underlying vascular changes and/or tau pathology. Meanwhile electrophysiological and neuroimaging investigations in epilepsy, Alzheimer’s disease, and vascular dementia have focused interest on network level dysfunction, which might be important in mediating cognitive dysfunction across all three of these conditions. In this review we consider whether seizures promote dementia, whether dementia causes seizures, or if common underlying pathophysiological mechanisms cause both. We examine the evidence that cognitive impairment is associated with epilepsy in older people (aged over 65) and the prognosis for patients with epilepsy developing dementia, with a specific emphasis on common mechanisms that might underlie the cognitive deficits observed in epilepsy and Alzheimer’s disease. Our analyses suggest that there is considerable intersection between epilepsy, Alzheimer’s disease and cerebrovascular disease raising

Objective: Small uncontrolled series suggest that treatment of obstructive sleep apnea (OSA) in patients with epilepsy may improve seizure control. Prior to conducting a definitive randomized controlled trial, we addressed critical design issues in a pilot study. Methods: We identified a cohort of adult patients with medically refractory epilepsy and coexisting OSA, documented by polysomnography (PSG). After an 8-week baseline period, subjects with OSA were randomized to therapeutic or sham continuous positive airway pressure (CPAP) for 10 weeks. Subjects maintained seizure calendars and antiepileptic drug dosages were held constant. Results: Sixty-eight subjects with suspected OSA were enrolled and 35 subjects randomized to therapeutic CPAP (22 subjects) or sham (13 subjects) CPAP. Male gender and an elevated sleep apnea questionnaire score were predictive of OSA on PSG. Nineteen subjects in the therapeutic group and all 13 subjects in the sham group completed the trial. Baseline apnea-hypopnea index (AHI) and CPAP adherence were comparable between groups. A significant reduction in AHI was observed in the therapeutic CPAP group as compared to the sham group. Subjects, study coordinators, and principal investigators were unable to predict treatment allocation. Conclusions: This pilot study provided critical information related to study design and feasibility for planning a comprehensive trial to test the hypothesis that treating obstructive sleep apnea in patients with epilepsy improves seizure control.

Almost a third of patients with epilepsy have a treatment-resistant form, which is associated with severe morbidity and increased mortality. Cannabis-based treatments for epilepsy have generated much interest, but scientific data are scarce. We aimed to establish whether addition of cannabidiol to existing anti-epileptic regimens would be safe, tolerated, and efficacious in children and young adults with treatment-resistant epilepsy. In this open-label trial, patients (aged 1-30 years) with severe, intractable, childhood-onset, treatment-resistant epilepsy, who were receiving stable doses of antiepileptic drugs before study entry, were enrolled in an expanded-access programme at 11 epilepsy centres across the USA. Patients were given oral cannabidiol at 2-5 mg/kg per day, up-titrated until intolerance or to a maximum dose of 25 mg/kg or 50 mg/kg per day (dependent on study site). The primary objective was to establish the safety and tolerability of cannabidiol and the primary efficacy endpoint was median percentage change in the mean monthly frequency of motor seizures at 12 weeks. The efficacy analysis was by modified intention to treat. Comparisons of the percentage change in frequency of motor seizures were done with a Mann-Whitney U test. Between Jan 15, 2014, and Jan 15, 2015, 214 patients were enrolled; 162 (76%) patients who had at least 12 weeks of follow-up after the first dose of cannabidiol were included in the safety and tolerability analysis, and 137 (64%) patients were included in the efficacy analysis. In the safety group, 33 (20%) patients had Dravet syndrome and 31 (19%) patients had Lennox-Gastaut syndrome. The remaining patients had intractable epilepsies of different causes and type. Adverse events were reported in 128 (79%) of the 162 patients within the safety group. Adverse events reported in more than 10% of patients were somnolence (n=41 [25%]), decreased appetite (n=31 [19%]), diarrhoea (n=31 [19%]), fatigue (n=21 [13%]), and convulsion (n

Childhood-onset epilepsy during the years of transition to adulthood may affect normal social, physical, and mental development, frequently leading to psychosocial and health-related problems in the long term. This study aimed to describe the main characteristics of patients in transition and to identify risk factors for poor psychosocial outcome in adolescents and young adults with epilepsy. Patients with epilepsy, 15-25years of age, who visited the Kempenhaeghe Epilepsy Transition Clinic from March 2012 to December 2014 were included (n=138). Predefined risk scores for medical, educational/occupational status, and independence/separation/identity were obtained, along with individual risk profile scores for poor psychosocial outcome. Multivariate linear regression analysis and discriminant analysis were used to identify variables associated with an increased risk of poor long-term psychosocial outcome. Demographic, epilepsy-related, and psychosocial variables associated with a high risk of poor long-term outcome were lower intelligence, higher seizure frequency, ongoing seizures, and an unsupportive and unstable family environment. Using the aforementioned factors in combination, we were able to correctly classify the majority (55.1%) of the patients regarding their risk of poor psychosocial outcome. Our analysis may allow early identification of patients at high risk of prevention, preferably at pretransition age. The combination of a chronic refractory epilepsy and an unstable family environment constitutes a higher risk of transition problems and poor outcome in adulthood. As a consequence, early interventions should be put into place to protect youth at risk of poor transition outcome. Copyright © 2015 Elsevier Inc. All rights reserved.

Perception and use of complementary and alternative medicine among children and adults with epilepsy: the importance of the decision makers.

The aim of the current study was to assess the extent to which complementary and alternative medicine (CAM) has been used in children and adults to treat seizures and to compare the perceptions and usage of CAM between adult patients who decides for themselves and adults who decide for their sick children.In this cross-sectional study, patients who have been treated for epilepsy for at least one year at the outpatient epilepsy clinic at the Shiraz University of Medical Sciences were interviewed from January 2012 through March 2012. The questionnaire collected specific information of CAM perceptions and usage among patients. Pearson Chi-Square and Student's t-test were used to compare variables among children group with adults group. Ninety-eight children (their caregivers) and 158 adults (themselves) participated. Adult patients (53%) more frequently believed that CAM might be useful in treating seizures than adults with sick kids (35%) (P = 0.0004). Herbal drugs, traditional medicine and exercise were more often considered as being helpful in treating seizures among adult patients compared to adults with sick children. CAM usage was not different among adult patients compared to adults with sick kids (P = 0.3). CAM is an option considered by many people with epilepsy to treat seizures. The individual who makes the decision as to use any of these unconventional treatment options is probably not different when it comes to self (the patient himself) vs. non-self (the parents/care-givers), despite the observed difference that adult patients more frequently believed that CAM might be useful in treating seizures than adults with sick kids.

The recognizable electroencephalography (EEG) pattern of ring chromosome 20 epilepsy syndrome can be missing in patients with r(20) chromosomal anomaly, and may be found in patients with frontal lobe epilepsy of other origin. This study aims to search for more specific EEG signs by using long-term recordings and measuring the duration of paroxysmal anomalies. The series included 12 adult patients with r(20) anomaly, and 12 controls without any chromosomal aberration. We measured the duration of every paroxysmal burst and calculated the sum of their durations for each long-term EEG recording. We compared patients to controls using the Mann-Whitney U-test. Every patient showed long-lasting paroxysmal EEG bursts, up to 60 min; controls did not show any bursts longer than 60 s (p < 0.0001). The total duration of paroxysmal anomalies was significantly longer in patients (31-692 min) compared to controls (0-48 min) (p < 0.0001). Thus, long-term recordings enhance the contribution of EEG methods for characterizing the ring 20 chromosome epilepsy syndrome. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

The revised terminology and concepts for the organization of seizures and epilepsy proposed by the ILAE Commission on Classification and Terminology in 2010 allows for a number of new opportunities in the study of cognition and behavior in adults. This review examines the literature that has looked for behavioral and cognitive correlates of the newly recognized genetic epilepsies in adults. While some studies report clear cognitive phenotypes associated with specific genetic mutations in adults with epilepsy, others report remarkable clinical heterogeneity. In the second part of this review, we discuss some of the factors that may influence the findings in this literature. Cognitive function is the product of both genetic and environmental influences. Neuropsychological phenotypes under direct genetic influence may be wider and more subtle than specific deficits within discreet cognitive domains and may be reflected in broader, multidimensional measures of cognitive function than those tapped by scores on standardized tests of function. Future studies must be carefully designed to reflect these factors. It is also imperative that studies with negative findings are assigned as much value as those with positive results and published accordingly.

Sexual dysfunction is an important but often neglected aspect of epilepsy. The objective of this study was to explore the prevalence and types of sexual problems in patients with epilepsy and compare the results with similar data obtained from a representative sample of the general population. At the National Centre for Epilepsy in Norway, 171 of 227 consecutive adult inpatients and outpatients with epilepsy (response rate: 75.3%) and their neurologists participated in a questionnaire study about epilepsy and sexuality. The results were compared with data available from 594 adult Norwegians who had completed the same questionnaire. Patients with epilepsy had a significantly higher prevalence of sexual problems (women: 75.3% vs. 12.0%; men: 63.3% vs. 9.6%). The most commonly reported problems (>30%) were reduced sexual desire, orgasm problems, erection problems, and vaginal dryness. The patients reported considerable dissatisfaction regarding sexual functioning. Significantly more sexual problems were found in patients of both sexes with reduced quality of life and in women with symptoms of depression. We found no significant association between sexual problems and age of epilepsy onset, type of epilepsy, or use of enzyme-inducing antiepileptic drugs. Whereas age at sexual debut did not differ between the patients with epilepsy and the general population, men with epilepsy had a lower number of partners during the last 12months, and the proportion of women with a low frequency of intercourse was higher in the group with epilepsy. In conclusion, sexual problems are significantly greater in Norwegian patients with epilepsy than in the general adult population. As no single epilepsy type or treatment could be identified as a specific predisposing factor, it seems likely that there are multiple causes underlying our results, including both organic and psychosocial factors.

To quantify the clinical and economic burden of uncontrolled epilepsy in patients requiring emergency department (ED) visit or hospitalization. Health insurance claims from a 5-state Medicaid database (1997Q1-2009Q2) and 55 self-insured US companies ("employer," 1999Q1 and 2008Q4) were analyzed. Adult patients with epilepsy receiving antiepileptic drugs (AED) were selected. Using a retrospective matched-cohort design, patients were categorized into cohorts of "uncontrolled" (≥ 2 changes in AED therapy, then ≥ 1 epilepsy-related ED visit/hospitalization within 1 year) and "well-controlled" (no AED change, no epilepsy-related ED visit/hospitalization) epilepsy. Matched cohorts were compared for health care resource utilization and costs using multivariate conditional regression models and nonparametric methods. From 110,312 (Medicaid) and 36,529 (employer) eligible patients, 3,454 and 602 with uncontrolled epilepsy were matched 1:1 to patients with well-controlled epilepsy, respectively. In both populations, uncontrolled epilepsy cohorts presented about 2 times more fractures and head injuries (all p values < 0.0001) and higher health care resource utilization (ranges of adjusted incidence rate ratios [IRRs] [all-cause utilization]: AEDs = 1.8-1.9, non-AEDs = 1.3-1.5, hospitalizations = 5.4-6.7, length of hospital stays = 7.3-7.7, ED visits = 3.7-5.0, outpatient visits = 1.4-1.7, neurologist visits = 2.3-3.1; all p values < 0.0001) than well-controlled groups. Total direct health care costs were higher in patients with uncontrolled epilepsy (adjusted cost difference [95% confidence interval (CI)] Medicaid = $12,258 [$10,482-$14,083]; employer = $14,582 [$12,019-$17,097]) vs well-controlled patients. Privately insured employees with uncontrolled epilepsy lost 2.5 times more work days, with associated indirect costs of $2,857 (95% CI $1,042-$4,581). Uncontrolled epilepsy in patients requiring ED visit or hospitalization was associated with significantly greater

Temporal lobe epilepsy surgery in children versus adults: from etiologies to outcomes

PubMed Central

Lee, Yun-Jin

2013-01-01

Temporal lobe epilepsy (TLE) is the most common type of medically intractable epilepsy in adults and children, and mesial temporal sclerosis is the most common underlying cause of TLE. Unlike in the case of adults, TLE in infants and young children often has etiologies other than mesial temporal sclerosis, such as tumors, cortical dysplasia, trauma, and vascular malformations. Differences in seizure semiology have also been reported. Motor manifestations are prominent in infants and young children, but they become less obvious with increasing age. Further, automatisms tend to become increasingly complex with age. However, in childhood and especially in adolescence, the clinical manifestations are similar to those of the adult population. Selective amygdalohippocampectomy can lead to excellent postoperative seizure outcome in adults, but favorable results have been seen in children as well. Anterior temporal lobectomy may prove to be a more successful surgery than amygdalohippocampectomy in children with intractable TLE. The presence of a focal brain lesion on magnetic resonance imaging is one of the most reliable independent predictors of a good postoperative seizure outcome. Seizure-free status is the most important predictor of improved psychosocial outcome with advanced quality of life and a lower proportion of disability among adults and children. Since the brain is more plastic during infancy and early childhood, recovery is promoted. In contrast, long epilepsy duration is an important risk factor for surgically refractory seizures. Therefore, patients with medically intractable TLE should undergo surgery as early as possible. PMID:23908666

To investigate electroencephalographic (EEG) features of benign adult familial myoclonic epilepsy (BAFME). We reviewed interictal EEG features in patients with BAFME treated between April 2005 and November 2012 at a tertiary referral center. The diagnostic criteria for BAFME were the presence of infrequent generalized tonic-clonic seizures, myoclonus or myoclonic seizures, and autosomal dominant inheritance. Interictal EEG findings of epilepsy with generalized tonic-clonic seizure only (EGTCS) were reviewed for comparison. We randomly selected 10 generalized spike/polyspike and wave complexes (GSW) for each BAFME patient and measured the duration of them. Photic stimulation and hyperventilation were performed in all. Nineteen (eight men, 11 women) patients with BAFME were included in this study. The mean frequency of GSW was 4.3±1.0Hz (mean±SD, n=14) in BAFME and 3.2±0.8Hz (n=10) in EGTCS. There was a statistically significant difference (p=0.008) between the two. Photoparoxysmal responses (PPR) were noted in 18 (95%) patients with BAFME but 1 (10%) with EGTCS. Faster frequency of GSW, compared with that in EGTCS, accompanied by PPR may be characteristic EEG features of BAFME. These findings may lead the diagnosis of BAFME.

Healthy People 2020, a national health promotion initiative, calls for increasing the proportion of U.S. adults who self-report good or better health. The Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Scale (GHS) was identified as a reliable and valid set of items of self-reported physical and mental health to monitor these two domains across the decade. The purpose of this study was to examine the percentage of adults with an epilepsy history who met the Healthy People 2020 target for self-reported good or better health and to compare these percentages to adults with history of other common chronic conditions. Using the 2010 National Health Interview Survey, we compared and estimated the age-standardized prevalence of reporting good or better physical and mental health among adults with five selected chronic conditions including epilepsy, diabetes, heart disease, cancer, and hypertension. We examined response patterns for physical and mental health scale among adults with these five conditions. The percentages of adults with epilepsy who reported good or better physical health (52%) or mental health (54%) were significantly below the Healthy People 2020 target estimate of 80% for both outcomes. Significantly smaller percentages of adults with an epilepsy history reported good or better physical health than adults with heart disease, cancer, or hypertension. Significantly smaller percentages of adults with an epilepsy history reported good or better mental health than adults with all other four conditions. Health and social service providers can implement and enhance existing evidence-based clinical interventions and public health programs and strategies shown to improve outcomes in epilepsy. These estimates can be used to assess improvements in the Healthy People 2020 Health-Related Quality of Life and Well-Being Objective throughout the decade. Published by Elsevier Inc.

The association of epilepsy with mental illness is described for years. Current is trying to relate certain epilepsies, such as juvenile myoclonic epilepsy (JME) with certain personality traits marked by emotional instability. We study a group of patients with JME and his mental state, with emphasis on the personality traits, presence of clinical anxiety or depression and quality of life, with other epilepsy patients versus a control group. Patients with epilepsy have more marked personality traits and symptoms of anxiety and depression, making a more negative assessment of their quality of life than the control group. Patients with others epilepsy have a higher other personality disorder and a poorer perception of their quality of life than patients with JME. Differences are obtained among patients with epilepsy and control groups in all the variables analyzed (personality, anxiety, depression and quality of life). JME patients have better scores on personality and quality of life than those in the other group of epilepsies.

Refractory epilepsy is an intrusive condition with important implications for daily functioning in emerging and young adulthood. The present study examined the degree to which refractory epilepsy is integrated in one's identity, and examined how such a sense of illness identity was related to health-related quality of life (HRQOL). A total of 121 18- to 40-year-old patients with refractory epilepsy (56.2% women) completed self-report questionnaires assessing the four illness identity states of acceptance, enrichment, engulfment, and rejection (Illness Identity Questionnaire (IIQ)); HRQOL (Quality of Life in Epilepsy Inventory - 31); and seizure frequency and severity (Liverpool Seizure Severity Scale (LSSS)). Illness identity scores were compared with a sample of 191 patients with a nonneurological chronic disease (congenital heart disease). Hierarchical regression analyses were conducted to assess the predictive value of illness identity for HRQOL when simultaneously controlling for demographic and clinical features. Patients with refractory epilepsy scored higher on rejection and engulfment and lower on acceptance when compared with patients with congenital heart disease. Further, seizure severity and number of medication side-effects were positively related to engulfment and negatively to acceptance. Finally, when simultaneously controlling for various demographic and clinical variables, illness identity significantly predicted HRQOL (with engulfment being the strongest and most consistent predictor). The extent to which patients with refractory epilepsy succeed in integrating their illness into their identity may have important implications for HRQOL. Clinicians should be especially attentive for signs that patients feel engulfed by their epilepsy. Copyright © 2018 Elsevier Inc. All rights reserved.

To compare the frequency of intrathecal immunoglobulin (Ig) synthesis in patients with symptomatic epilepsy and epilepsy of unknown etiology ('cryptogenic'). Patients with epileptic (n = 301) and non-epileptic (n = 10) seizures were retrospectively screened for autochthonous intrathecal Ig synthesis and oligoclonal bands (OCBs) in the cerebrospinal fluid. Intrathecal IgG/OCBs were detected in 8% of patients with epilepsies of unknown etiology, 5% of patients with first seizures of unknown cause and 0-4% of patients with epilepsy due to brain tumors, cerebrovascular disease or other etiologies. Intrathecal IgG/OCBs were not seen in patients with psychogenic seizures. Identical OCBs in serum and cerebrospinal fluid were more common in all patient groups (10-40% depending on underlying etiology). Intrathecal IgG synthesis/OCBs were observed slightly more frequently in patients with 'cryptogenic' epilepsy and with first seizures of unknown etiology than in other patient groups. However, this remained an infrequent finding and thus we could not confirm humoral immunity as a leading disease mechanism in patients with epilepsy in general or with unknown etiology in particular. © 2017 EAN.

We investigated the marital status of the patients with epilepsy to clarify the clinical factors impeding improvement of the quality of life in adults with epilepsy. We examined the marital status of adult patients with epilepsy who did not have mental retardation and had been treated at Hirosaki University Hospital, Hirosaki, Japan, for >5 years. The present study included 278 patients (142 men and 136 women) ranging from age 20 to 60 years. Sixty-six men and 52 women were single. Seventy-six males and 84 females had been married. The present study investigated the proportion of patients in whom seizures were controlled at the time of marriage. Percentages were only 30% for men and 22% for women. This result showed that in many patients, seizures were not controlled when they were married, which suggests that seizures themselves may not markedly inhibit marriage. Thirteen men and 16 women (total, 29 patients) had experienced divorce. Epilepsy was the cause of divorce in seven of the 29 patients who had been divorced. Of these seven patients, only one patient had informed the spouse of the disease before marriage. In the remaining six patients, seizures were witnessed after marriage or the disease was revealed by medication, which resulted in divorces. Concerning the association between marriage and the job, a close relation was found between the presence or absence of marriage and the presence or absence of a job among male patients.

Intellectual disability (ID) is relatively common in people with epilepsy, with prevalence estimated to be around 25%. Surprisingly, given this relatively high frequency, along with higher rates of refractory epilepsy than in those without ID, little is known about outcomes of different management approaches/clinical services treating epilepsy in adults with ID-we investigate this area. We undertook a naturalistic observational cohort study measuring outcomes in n = 91 adults with ID over a 7-month period (recruited within the period March 2008 to April 2010). Participants were receiving treatment for refractory epilepsy (primarily) in one of two clinical service settings: community ID teams (CIDTs) or hospital Neurology services. The pattern of comorbidities appeared important in predicting clinical service, with Neurologists managing the epilepsy of relatively more of those with neurological comorbidities whilst CIDTs managed the epilepsy of relatively more of those with psychiatric comorbidities. Epilepsy-related outcomes, as measured by the Glasgow Epilepsy Outcome Scale 35 (GEOS-35) and the Epilepsy and Learning Disabilities Quality of Life Scale (ELDQoL) did not differ significantly between Neurology services and CIDTs. In the context of this study, the absence of evidence for differences in epilepsy-related outcomes amongst adults with ID and refractory epilepsy between mainstream neurology and specialist ID clinical services is considered. Determining the selection of the service managing the epilepsy of adults with an ID on the basis of the skill sets also required to treat associated comorbidities may hence be a reasonable heuristic.

Controversy exists regarding the similarity between depression as seen in patients with epilepsy and in those with idiopathic major depression. The objective of this study was to examine whether anger is a distinctive feature of depression in epilepsy. Participants included 487 adult patients with epilepsy (study group) and 85 patients with idiopathic major depression according to Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) criteria, and without other neurological complications (control group). All participants completed the Inventory of Depressive Symptomatology Self-Report (IDS-SR) and the Buss-Perry Aggression Questionnaire (BAQ). The IDS-SR is a self-report questionnaire that measures depression severity and assesses all symptoms of depression as defined by the DSM-IV. The BAQ is a self-rating scale designed for assessing aggression. After examining potential confounding factors (i.e., demographic and clinical variables) using a multivariate linear regression model, BAQ scores were compared between the study (n = 85) and control groups (n = 54) for patients with moderate or severe depression using established cut-off points (IDS-SR score > 25). BAQ scores were significantly higher in the study group (P = 0.009). Among the BAQ subscales, only anger showed a statistically significant difference (P = 0.013). Although a significant correlation was revealed between the IDS-SR and BAQ scores in the study group, no such correlation was found in the control group. Thus, anger might be a constituent component of depression among epilepsy patients, but not among idiopathic major depression patients.

The purpose of this study was to test the psychometric properties of an enhanced Adult Epilepsy Self-Management Measurement Instrument (AESMMI). An instrument of 113 items, covering 10 a priori self-management domains, was generated through a multiphase process, based on a review of the literature, validated epilepsy and other chronic condition self-management scales and expert input. Reliability and exploratory factor analyses were conducted on data collected from 422 adults with epilepsy. The instrument was reduced to 65 items, converging on 11 factors: Health-care Communication, Coping, Treatment Management, Seizure Tracking, Social Support, Seizure Response, Wellness, Medication Adherence, Safety, Stress Management, and Proactivity. Exploratory factors supported the construct validity for 6 a priori domains, albeit with significant changes in the retained items or in their scope and 3 new factors. One a priori domain was split in 2 subscales pertaining to treatment. The configuration of the 11 factors provides additional insight into epilepsy self-management behaviors. Internal consistency reliability of the 65-item instrument was high (α=.935). Correlations with independent measures of health status, quality of life, depression, seizure severity, and life impact of epilepsy further validated the instrument. This instrument shows potential for use in research and clinical settings and for assessing intervention outcomes and self-management behaviors in adults with epilepsy. Copyright © 2015 Elsevier Inc.

Objective: To investigate prospective, population-based long-term outcomes concerning seizures and antiepileptic drug (AED) treatment after resective epilepsy surgery in Sweden. Methods: Ten- and 5-year follow-ups were performed in 2005 to 2007 for 278/327 patients after resective epilepsy surgery from 1995 to 1997 and 2000 to 2002, respectively. All patients had been prospectively followed in the Swedish National Epilepsy Surgery Register. Ninety-three patients, who were presurgically evaluated but not operated, served as controls. Results: In the long term (mean 7.6 years), 62% of operated adults and 50% of operated children were seizure-free, compared to 14% of nonoperated adults (p < 0.001) and 38% of nonoperated children (not significant). Forty-one percent of operated adults and 44% of operated children had sustained seizure freedom since surgery, compared to none of the controls (p < 0.0005). Multivariate analysis identified ≥30 seizures/month at baseline and long epilepsy duration as negative predictors and positive MRI to be a positive predictor of long-term seizure-free outcome. Ten years after surgery, 86% of seizure-free children and 43% of seizure-free adults had stopped AEDs in the surgery groups compared to none of the controls (p < 0.0005). Conclusions: This population-based, prospective study shows good long-term seizure outcomes after resective epilepsy surgery. The majority of the patients who are seizure-free after 5 and 10 years have sustained seizure freedom since surgery. Many patients who gain seizure freedom can successfully discontinue AEDs, more often children than adults. Classification of evidence: This study provides Class III evidence that more patients are seizure-free and have stopped AED treatment in the long term after resective epilepsy surgery than nonoperated epilepsy patients.

Epilepsy & IQ: the clinical utility of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) indices in the neuropsychological assessment of people with epilepsy.

PubMed

Baxendale, Sallie; McGrath, Katherine; Thompson, Pamela J

2014-01-01

We examined Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) General Ability Index (GAI) and Full Scale Intelligence Quotient (FSIQ) discrepancies in 100 epilepsy patients; 44% had a significant GAI > FSIQ discrepancy. GAI-FSIQ discrepancies were correlated with the number of antiepileptic drugs taken and duration of epilepsy. Individual antiepileptic drugs differentially interfere with the expression of underlying intellectual ability in this group. FSIQ may significantly underestimate levels of general intellectual ability in people with epilepsy. Inaccurate representations of FSIQ due to selective impairments in working memory and reduced processing speed obscure the contextual interpretation of performance on other neuropsychological tests, and subtle localizing and lateralizing signs may be missed as a result.

Lacosamide as adjunctive therapy in refractory epilepsy in adults: a systematic review.

To review the evidence for efficacy and safety of lacosamide in adult patients with refractory epilepsy and refractory status epilepticus (RSE). A systematic literature search of MEDLINE, PubMed, EMBASE, IPA, Google and Google Scholar (through October 2014) was performed. Fourteen studies assessing lacosamide in 3509 refractory epilepsy patients were included. In 3 RCTs, more patients had at least 50% reduction in seizure frequency with lacosamide compared to placebo with 38.3-41.1%, 38.1-41.2%, and 18.3-25.8%, in the 400 mg/day, 600 mg/day, and placebo groups, respectively. In non-comparative trials, 18-69% of patients achieved at least 50% reduction in seizure frequency, and 1.7-26.2% achieved seizure freedom. Non-responders were documented in two trials, with 26.2-34% having no response. Thirteen studies assessing lacosamide in 390 RSE patients were included. When assessing lacosamide's ability to terminate RSE, one comparative cohort study found no improvement in SE duration or seizure control with addition of lacosamide. Another study documented no difference compared to use of phenytoin. Eleven descriptive studies using lacosamide as add-on RSE therapy revealed seizure termination rates of 0-100% (median 64.7%). In all patients receiving lacosamide, dizziness (21.8%), vision disturbances (10.4%), drowsiness (7.4%), headache (7.0%), nausea (6.5%), and coordination problems (5.8%) were the most common adverse effects. Based on evidence to date, adjunctive lacosamide is a treatment option to reduce seizure frequency in patients with refractory epilepsy and terminate seizures in patients with RSE. The safety information summary can be used to advise patients of potential adverse effects. Copyright © 2014 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

Age at onset in patients with medically refractory temporal lobe epilepsy and mesial temporal sclerosis: impact on clinical manifestations and postsurgical outcome.

To evaluate the demographic and clinical manifestations and postsurgical outcome of childhood-onset mesial temporal sclerosis and temporal lobe epilepsy (MTS-TLE) and establishing the potential differences as compared to the patients with adult-onset MTS-TLE. In this retrospective study all patients with a clinical diagnosis of medically refractory TLE due to mesial temporal sclerosis, who underwent epilepsy surgery at Jefferson comprehensive epilepsy center, were recruited. Patients were prospectively registered in a database from 1986 through 2014. Postsurgical outcome was classified into two groups; seizure-free or relapsed. Clinical manifestations and outcome were compared between patients with childhood-onset MTS-TLE (i.e., age at onset of the first afebrile habitual seizure below 10 years) and those with adult-onset MTS-TLE (i.e., age at onset of the first afebrile habitual seizure 20 years or above). One hundred and twelve patients had childhood-onset MTS-TLE and 76 had adult-onset MTS-TLE. Demographic, clinical, EEG and MRI characteristics of these two groups were similar. Postoperative outcome was not statistically different between these two groups of patients (P=0.9). Temporal lobe epilepsy due to mesial temporal sclerosis is a common cause of epilepsy that can start from early childhood to late adulthood. The etiology of MTS-TLE may be different in various age groups, but it seems that when mesial temporal sclerosis is the pathological substrate of TLE, clinical manifestations and response to surgical treatment of patients are very similar in patients with childhood-onset MTS-TLE compared to those with adult-onset disease.

Baca, Christine B.; Rychlik, Karen; Vickrey, Barbara G.; Caplan, Rochelle; Testa, Francine M.; Levy, Susan R.

2016-01-01

BACKGROUND: Adults with childhood-onset epilepsy experience poorer adult social outcomes than their peers. The relative roles of seizures over time versus learning and psychiatric problems are unclear. METHODS: We examined independent influences of psychiatric and learning disorders and of seizure course in 241 young adults (22–35 years old) with uncomplicated epilepsy in a longitudinal community-based cohort study. Social outcomes were ascertained throughout the study. A history of psychiatric and learning problems was ascertained ∼9 years after study entry. Seizure course was: “Excellent,” no seizures after the first year, in complete remission at last contact (N = 95, 39%); “Good,” seizures occurred 1 to 5 years after diagnosis, in complete remission at last contact (N = 56, 23%); “Fluctuating,” more complicated trajectories, but never pharmacoresistant (N = 70, 29%); “Pharmacoresistant,” long-term pharmacoresistant (N = 20, 8%). Multiple logistic regression was used to identify contributors to each social outcome. RESULTS: Better seizure course predicted college completion, being either employed or pursuing a degree, and driving, but was not substantially associated with other social outcomes. Poorer seizure course was associated with a greater likelihood of having offspring, particularly in women without partners. Learning problems, psychiatric disorders, or both negatively influenced all but 2 of the social outcomes. CONCLUSIONS: In young adults with uncomplicated epilepsy, the course of seizures contributed primarily to education, employment, and driving. A history of learning problems and psychiatric disorders adversely influenced most adult outcomes. These findings identify potential reasons for vocational and social difficulties encountered by young adults with childhood epilepsy and areas to target for counseling and transition planning.

The proportion of adults with epilepsy using the emergency department (ED) is high. Among this patient population, increased frequency of office-based provider visits may be associated with lesser frequency of ED encounters, and key patient features may be linked to more ED encounters. We analyzed the Medical Expenditure Panel Survey Household Component (MEPS-HC) dataset for years 2003-2014, which represents a weighted sample of 842,249 publicly-insured US adults aged ≥18years. The Hurdle Poisson model that accommodates excess zeros was used to estimate the association between office-based and ED visits. Annual mean ED and office-based visits for publicly-insured adults with epilepsy were 0.70 and 10.8 respectively. Probability of at least one ED visit was 0.4% higher for every unit of office-based visit. Individuals in the high income category were less likely to visit the ED at least once while women with epilepsy had a higher likelihood of visiting the ED at least once. Among those who visited the ED at least once, there was a 0.3% higher likelihood of visiting the ED for every unit of office-based visit. Among individuals who visited the ED at least once, being aged 45-64years, residing in the West, and the year 2011/14 were associated with higher ED visits. In this representative sample of publicly-insured adults with epilepsy, higher frequency of office visits was not associated with lower ED utilization, which may be due to underlying greater disease severity or propensity for more treatment complications.

2010-05-01

To evaluate health care resource utilization (HRU) in active epilepsy. Thomson-Reuters insurance databases included 14 million persons in 2005-2007. We extracted information for individuals with insurance claims suggestive of epilepsy. Using iterative expert classification, we sorted patients by type of epilepsy. For each type we calculated prevalence and HRU. A distance analysis identified closely similar types, and a principal components analysis revealed dimensions of variation in HRU. The prevalence of active epilepsy was 3.4 per 1,000. Most common diagnoses among 46,847 patients were generalized convulsive epilepsy (33.3%) and complex partial seizures (24.8%). Patients averaged 10 physician visits per year, 24 diagnostic tests/procedures per year, >30 drug dispensings per year, and <1 emergency room (ER) visit per year, the minority of each of these being related to epilepsy. Female patients generally had more HRU, and HRU increased with age. Patients were hospitalized most frequently for disorders other than epilepsy. HRU was similar for most epilepsy types, excepting grand mal status, epilepsia partialis continua, and infantile spasms. The first principal components of HRU variation was nonepilepsy HRU, followed by components of epilepsy-related medications, other epilepsy/emergency care, and epilepsy visits/diagnostic procedures. The prevalence of active epilepsy in the United States is substantially less than the prevalence of any history of recurrent seizure. Nonepilepsy-related HRU dominated HRU in epilepsy patients and was the principal source of variation. There is a core set of epilepsy diagnoses, the HRU patterns of which are indistinguishable, whereas patients with grand mal status, epilepsia partialis continua, and infantile spasms all have distinct patterns. To provide more specific insights into the economic impact of the condition, studies of HRU in epilepsy should make a distinction about epilepsy-related and unrelated care.

Evaluation of knowledge about epilepsy and attitudes towards patients with epilepsy among university students in Upper Egypt.

Epilepsy is a major public health problem worldwide. There are many misconceptions about people's knowledge and attitudes about epilepsy, which influence people's behavior towards patients with epilepsy. We conducted a cross-sectional study in Sohag University, a public Egyptian University, in Upper Egypt. We used an Arabic language designed questionnaire to assess people's knowledge about epilepsy and their attitudes towards patients with epilepsy. We included a total of 920 students in the study. 12.4% of study respondents had never heard of or read about epilepsy. Moreover, there was much misunderstanding about the etiology of epilepsy, as 68.2% of epileptic and 74.5% of nonepileptic respondents believe epilepsy is caused by evil spirits and evil eyes or due to psychiatric disorders. There were also many people who held negative attitudes towards patients with epilepsy in regards to major life milestones such as marriage and having children. Among nonepileptics, 54.5% believe epileptics should not marry and 49.9% believe they should not have children. Among patients with epilepsy, these percentages are 27.3% and 36.4% respectively. Knowledge about epilepsy is insufficient and should be increased. The attitudes towards patients with epilepsy are negative and should be changed in Upper Egypt. Copyright © 2018 Elsevier B.V.

Epilepsy is the most common non-infectious neurologic disease in developing countries such as Africa, including Nigeria. This study was designed to assess the intellectual performance of patients with epilepsy (PWE) in Nigeria hoping that the result will serve as the basis for educational, vocational, and social counseling. Forty-one PWE were studied along with 41 age-, sex- and education-matched healthy controls. A questionnaire was developed and applied to all subjects and history was taken from patients and eyewitness. The intellectual function of each subject was assessed with the aid of Wechsler Adult Intelligence Scale adapted for Nigerians. All patients subsequently had electroencephalography (EEG) performed and the EEG findings were noted. SPSS statistical package was used to analyze the data. The PWE performed poorly on the verbal IQ, performance IQ, and full scale IQ scores when compared with controls (P < 0.05) and 20% of PWE had mental retardation. Long duration of epilepsy, long duration of antiepileptic drug therapy, younger age at onset of epilepsy, increased frequency of seizures, and low educational status were found to have negative impacts on intellectual performance in PWE (P < 0.05) while seizure types and type of antiepileptic drugs (carbamazepine or phenytoin) did not influence intellectual performance. This study shows that PWE had significant intellectual impairment when compared with controls. In addition, long duration of epilepsy, long duration of AED therapy, earlier age of onset, increased seizure frequency, and low educational status had a negative impact on intellectual functioning in PWE.

The rapid achievement of effective levels of antiepileptic drugs (AEDs) is required in patients with epilepsy who have a higher risk of seizures, and oral loading of AEDs may be an important consideration in these patients. We performed the present study to investigate the efficacy and tolerability of oral loading of oxcarbazepine in patients with recurrent seizures, or after temporary discontinuation of AEDs for diagnostic or presurgical evaluation of epilepsy. Forty adult patients were studied and oxcarbazepine was administered orally at a single loading dosage of 30 mg/kg. The plasma levels of oxcarbazepine and its active metabolite, 10,11-dihydro-10-hydroxy-carbazepine (monohydroxy derivative, MHD), were measured, and clinical assessment of adverse events was performed at 2, 4, 6, 8, 10, 12, 16, and 24 h after oral loading of oxcarbazepine. Approximately two-thirds of patients reached effective levels of MHD 2 h after receiving the oral loading, and all patients reached effective levels 4 h after oxcarbazepine administration. Most patients maintained therapeutic MHD levels for at least 16 h. Almost half of the patients experienced adverse events, but all were mild to moderate in severity and resolved spontaneously within 24 h. Our study shows that oral loading of oxcarbazepine is an effective and well-tolerated method for rapidly achieving therapeutic levels of MHD in patients with epilepsy, and is a useful option in selected patients with recurrent seizures, or after temporary discontinuation of AEDs.

We aimed to compare long-term social outcomes in young adults with childhood-onset epilepsy (cases) with neurologically normal sibling controls. Long-term social outcomes were assessed at the 15-year follow-up of the Connecticut Study of Epilepsy, a community-based prospective cohort study of children with newly diagnosed epilepsy. Young adults with childhood-onset epilepsy with complicated (abnormal neurologic exam findings, abnormal brain imaging with lesion referable to epilepsy, intellectual disability (ID; IQ < 60) or informative history of neurologic insults to which the occurrence of epilepsy might be attributed), and uncomplicated epilepsy presentations were compared to healthy sibling controls. Age, gender, and matched-pair adjusted generalized linear models stratified by complicated epilepsy and 5-year seizure-free status estimated adjusted odds ratios (aORs) and 95% confidence intervals [CIs] for each outcome. The 15-year follow-up included 361 individuals with epilepsy (59% of initial cases; N = 291 uncomplicated and N = 70 complicated epilepsy; mean age 22 years [standard deviation, SD 3.5]; mean epilepsy onset 6.2 years [SD 3.9]) and 173 controls. Social outcomes for cases with uncomplicated epilepsy with ≥5 years terminal remission were comparable to controls; cases with uncomplicated epilepsy <5 years seizure-free were more likely to be less productive (school/employment < 20 h/week) (aOR 3.63, 95% CI 1.83-7.20) and not to have a driver's license (aOR 6.25, 95% CI 2.85-13.72). Complicated cases with epilepsy <5 years seizure-free had worse outcomes across multiple domains; including not graduating high school (aOR 24.97, 95% CI 7.49-83.30), being un- or underemployed (<20 h/week) (aOR 11.06, 95% CI 4.44-27.57), being less productively engaged (aOR 15.71, 95% CI 6.88-35.88), and not living independently (aOR 10.24, 95% CI 3.98-26.36). Complicated cases without ID (N = 36) had worse outcomes with respect to productive engagement (aOR 6.02; 95% CI 2

Complementary and alternative medicine (CAM) is recognized to be commonly used by patients, yet there have been few studies regarding the scope of CAM use by patients with epilepsy. This study assessed usage and perceptions of CAM by patients with epilepsy in the midwest of the United States. A 25-item survey was administered to adult patients with epilepsy, and data were collected from 228 patients. The survey collected demographics, specific CAM usage, adverse effects of CAM therapy, and perceptions of the effectiveness of CAM. Thirty-nine percent reported using CAM; 25% reported using CAM specifically for their epilepsy. Prayer/spirituality was the most commonly used form of CAM (46%), followed by "mega" vitamins (25%), chiropractic care (24%), and stress management (16%). CAM use is common among midwestern patients with epilepsy, although the pattern of use may be slightly different than in other regions of the United States and elsewhere.

Lacosamide: A Review in Focal Seizures in Patients with Epilepsy.

PubMed

Scott, Lesley J

2015-12-01

Lacosamide (Vimpat(®)) is a functionalized amino acid available orally (as a solution or tablets) and as an intravenous infusion for use as monotherapy (only in the USA) or adjunctive therapy for the treatment of focal seizures in adult and adolescent (aged ≥17 years in the USA) patients with epilepsy. As adjunctive therapy to other antiepileptic drugs (AEDs), lacosamide provided effective seizure control and was generally well tolerated in adults and adolescents (aged ≥16 years) in randomized clinical trials and in the real-world setting. In clinical trials, adjunctive lacosamide provided significantly greater reductions in 28-day seizure rates than adjunctive placebo, with these benefits maintained after up to 8 years of therapy in open-label extension studies. Moreover, patients were effectively switched from oral to short-term intravenous adjunctive therapy at the same dosage, which may be particularly beneficial in situations where oral therapy is not suitable. Conversion to lacosamide monotherapy was superior to a historical-control cohort in patients with focal seizures converting from previous AED therapy. In the absence of head-to-head comparisons with other AEDs, the exact position of lacosamide relative to other AEDs remains to be fully determined. In the meantime, oral and intravenous lacosamide provides a useful option as monotherapy (only in the USA) or adjunctive therapy for the treatment of focal seizures in adult and adolescent (aged ≥17 years in the USA) patients with epilepsy.

Surgery for epilepsy dates back to 1886 and has undergone significant developments. Today it is considered a key treatment modality in patients who are resistant to pharmacological intervention. It improves seizure control, cognition and quality of life. New technologies, advances in surgical technique and progress in scientific research underlie the expansion of surgery in epilepsy treatment. Effectiveness of surgical treatment depends on several factors including the type of epilepsy, the underlying pathology and the localisation of the epileptogenic zone. Timely referral to an experienced epilepsy surgery centre is important to allow the greatest chance of seizure control and to minimise associated morbidity and mortality. Following referral, patients undergo thorough presurgical investigation to evaluate their suitability for surgery. The commonest form of epilepsy treated by surgery is mesial temporal lobe sclerosis and there is Class I evidence for the medium-term efficacy of temporal lobe resection from two randomised control trials. Various other forms of epilepsy are now considered for resective and neuromodulatory surgical intervention due to favourable results. In this article, the authors review the current status of surgical treatment for epilepsy including the presurgical evaluation of patients, surgical techniques and the future directions in epilepsy surgery.

Long-term outcomes of surgical treatment for epilepsy in adults with regard to seizures, antiepileptic drug treatment and employment.

PubMed

Malmgren, Kristina; Edelvik, Anna

2017-01-01

There is Class I evidence for short-term efficacy of epilepsy surgery from two randomized controlled studies of temporal lobe resection. Long-term outcome studies are observational. The aim of this narrative review was to summarise long-term outcomes taking the study methodology into account. A PubMed search was conducted identifying articles on long-term outcomes of epilepsy surgery in adults with regard to seizures, antiepileptic drug treatment and employment. Definitions of seizure freedom were examined in order to identify the proportions of patients with sustained seizure freedom. The quality of the long-term studies was assessed. In a number of high-quality studies 40-50% of patients had been continuously free from seizures with impairment of consciousness 10 years after resective surgery, with a higher proportion seizure-free at each annual follow-up. The proportion of seizure-free adults in whom AEDs have been withdrawn varied widely across studies, from 19-63% after around 5 years of seizure freedom. Few long-term vocational outcome studies were identified and results were inconsistent. Some investigators found no postoperative changes, others found decreased employment for patients with continuing seizures, but no change or increased employment for seizure-free patients. Having employment at baseline and postoperative seizure freedom were the strongest predictors of employment after surgery. Long-term studies of outcomes after epilepsy surgery are by necessity observational. There is a need for more prospective longitudinal studies of both seizure and non-seizure outcomes, considering individual patient trajectories in order to obtain valid outcome data needed for counselling patients about epilepsy surgery.

Age- and sex-related differences in body composition could affect the pharmacokinetic parameters of administered drugs. The purpose of this post hoc analysis was to investigate the influences of age and sex on the pharmacokinetics of lacosamide. This post hoc analysis used pharmacokinetic data taken at steady state from (i) two phase I studies of oral lacosamide in healthy adult subjects (n = 66), and (ii) a population pharmacokinetic analysis carried out using data from two phase III studies of adjunctive oral lacosamide in adults (n = 565) with focal epilepsy taking 1-3 concomitant anti-epileptic drugs. Phase I data were stratified by age and sex as 'younger female' (aged 18-40 years), 'younger male' (aged 18-45 years) or 'elderly male/female' (aged ≥65 years), then normalized by body weight (lean body weight or fat-free mass), height or volume of distribution, and analysed using non-compartmental analysis. Population pharmacokinetic data were stratified by sex and analysed using a one-compartment model. Minor numerical differences between lacosamide exposure [the area under the concentration-time curve at steady state over the dosage interval (AUCτ,ss)] and the maximum plasma concentration at steady state (C max,ss) in subjects of different ages or sexes were noted. The differences could be explained by a scaling factor between the drug applied and the plasma concentration. Following normalization by lean body weight or volume of distribution, an analysis of relative bioavailability resulted in 90 % confidence intervals of the ratios for AUCτ,ss and C max,ss for age (elderly to younger) or sex (male to female) falling within the range accepted for equivalence (80-125 %); without normalization, the 90 % confidence intervals were outside this range. Minor numerical differences in lacosamide plasma concentrations were noted in the comparison between male and female patients (aged 16-71 years) with focal epilepsy.

Clinical observations suggest that psychogenic non-epileptic seizure (PNES) patients often have severe migraine, more severe than epilepsy patients. Investigations into migraine characteristics in patients with PNES are lacking. In this study we tested the hypothesis that, compared to epilepsy patients, PNES patients have more severe migraine, with more frequent and longer duration attacks that cause greater disability. In this observational study, 633 patients with video-EEG proven epilepsy or PNES were identified from the Mayo Clinic Epilepsy Monitoring Unit database. Contacted patients were screened for migraine via a validated questionnaire, and when present, data regarding migraine characteristics were collected. Two-sample t-tests, chi square analyses, and Mann-Whitney U tests were used to compare migraine characteristics in PNES patients to those of epilepsy patients. Data from 43 PNES patients with migraine and 29 epilepsy patients with migraine were available. Compared to epilepsy patients, PNES patients reported having more frequent headaches (mean 15.1 ± 9.8 vs. 8.1 ± 6.6 headache days/month, p<.001), more frequent migraine attacks (mean 6.5 ± 6.3 vs. 3.8. ± 4.1 migraines/month, p=.028), longer duration migraines (mean 39.5 ± 28.3 vs. 27.3 ± 20.1h, p=.035), and more frequently had non-visual migraine auras (78.6% vs. 46.7% of patients with migraine auras, p=.033). Migraine-related disability scores were not different between PNES and epilepsy patients (median 39, interquartile range 89 vs. 25, interquartile range 60.6, p=.15). Compared to epilepsy patients with migraine, PNES patients with migraine report having a more severe form of migraine with more frequent and longer duration attacks that are more commonly associated with non-visual migraine auras.

To determine the quality of life of patients with epilepsy and its relationship with depression, and the clinical and sociodemographic variables. This was a cross-sectional study in which a total of 120 epilepsy patients were recruited from a neurology outpatient clinic. Sociodemographic and clinical variables were recorded. Hospital Anxiety and Depression Scale (HADS) and Mini International Neuropsychiatric Interview (M.I.N.I.) were used to screen and diagnose for depression, respectively. Quality of Life Inventory of Epilepsy (QOLIE-31) was used to assess quality of life. Patients with epilepsy with major depression had poorer quality life (36.4 ± 1.8) compared to those without depression (41.7 ± 3.8, P < 0.001). Depression, having one seizure or more per month and having seizures within one month of interview were correlated with poorer quality of life, P < 0.001. Multivariate linear regression analyses showed that depression and recent seizures predicted having poorer quality of life in patients with epilepsy. Depression and poor seizure control were predictors for poor quality of life in patients with epilepsy. Therefore, epilepsy patients should be regularly screened for depression and treatment for epilepsy must be optimized to minimize the negative impact of having epilepsy for these patients.

Sudden unexpected death in epilepsy following resective epilepsy surgery in two patients withdrawn from anticonvulsants.

PubMed

Mansouri, Alireza; Alhadid, Kenda; Valiante, Taufik A

2015-09-01

We report sudden unexpected death in epilepsy (SUDEP) following resective epilepsy surgery in two patients who had been documented as seizure free. One patient had been weaned off of anticonvulsants and was leading a normal life. The other patient had discontinued only one anticonvulsant but had recently started working night shifts. Following resective epilepsy surgery, one of the major objectives among patients, caregivers, and the healthcare team is to safely wean patients off anticonvulsant medications. The main concern regarding anticonvulsant withdrawal is seizure recurrence. While SUDEP following surgical resection has been reported, to our knowledge, there have been no confirmed cases in patients who have been seizure free. Considering the patients reported here, and given that there are no concrete guidelines for the safe withdrawal of anticonvulsants following epilepsy surgery, the discontinuation of anticonvulsants should be considered carefully and must be accompanied by close monitoring and counseling of patients regarding activities that lower seizure threshold, even after successful epilepsy surgery.

2017-10-04

Language and social skills are essential for intrapersonal and interpersonal functioning and quality of life. Since epilepsy impacts these important domains of individuals' functioning, understanding the psychosocial and biological factors involved in the relationship among epilepsy, language, and social skills has important theoretical and clinical implications. This review first describes the psychosocial and biological factors involved in the association between language and social behavior in children and in adults and their relevance for epilepsy. It reviews the findings of studies of social skills and the few studies conducted on the inter-relationship of language and social skills in pediatric and adult epilepsy. The paper concludes with suggested future research and clinical directions that will enhance early identification and treatment of epilepsy patients at risk for impaired language and social skills.

Transition from pediatric to adult health care for adolescents with epilepsy is challenging for the patient, family, and health care workers. This paper is the first of three that summarize the main findings from the 2nd Symposium on Transition in Epilepsies, held in Paris from June 14-25, 2016. In this paper we describe five basic themes that have an important effect on transition. First, there are important brain changes in adolescence that leave an imbalance between risk taking and pleasure seeking behaviors and frontal executive function compared with adults. Second, puberty is a major change during the transition age. The three most important but separate neuroendocrine axes involved in puberty are gonadarche (activation of the gonads), adrenarche (activation of adrenal androgen production), and activation of the growth hormone-insulin like growth factor. Third, sexual debut occurs during the transition years, and at an earlier age in adolescents with epilepsy than controls. Adult sexual performance is often unsatisfactory. Although AED-induced alterations in sexual hormones and temporal lobe epilepsy may play a role in hyposexuality, depression, anxiety, and other social factors appear most important. Fourth, psychological development is very important with an evolution from an early stage (ages 10-13years) with concrete thinking, to a middle stage (ages 14-17) with analytic and more abstract introspective thinking, and then to a late stage (ages 18-21) with at least the beginnings of adult reasoning. Epilepsy may derail this relatively orderly progression. Adolescents with autistic spectrum disorder may present with severe behavior problems that are sometimes related to undiagnosed epilepsy. Fifth, bone health in adolescence is critical to establish adequate mineralization for all of adult life. While AED interference with Vitamin D metabolism is important, there is evidence that the effects of AEDs on bone are more complex and involve changes in remodeling

Dietary therapy is the best option for refractory nonsurgical epilepsy.

Ketogenic diet therapies for epilepsy have been described since the fifth century and published in scientific literature since the early 1900s. Since that time, the diet's popularity has waxed and waned as newer drugs and other treatments have been introduced. However, in recent years, dietary therapy for epilepsy has been increasingly accepted by physicians and desired by patients as an alternative to new drugs and neurostimulation. The introduction of less restrictive versions of the classic ketogenic diet, such as the modified Atkins diet (MAD), have led to increased numbers of adult patients with refractory epilepsy who are initiating dietary treatment. Approximately half of adults and children who start a ketogenic diet have a >50% seizure reduction, which is impressive given that these patients typically have medically refractory epilepsy. We believe that ketogenic dietary treatment is the best option for children and adults with refractory nonsurgical epilepsy due to its efficacy, rapid seizure reduction, synergistic effects with other antiseizure treatments, known and treatable side effects, potential to treat comorbid medical conditions, and worldwide availability.

Lennox-Gastaut syndrome (LGS) is a devastating childhood-onset epilepsy syndrome. The cause is unknown in 25% of cases. Little has been described about the specific clinical or electroencephalography (EEG) features of LGS of unknown or genetic cause (LGS(u)). The Epilepsy Phenome/Genome Project (EPGP) aims to characterize LGS(u) by phenotypic analysis of patients with LGS(u) and their parents. One hundred thirty-five patients with LGS with no known etiology and their parents were enrolled from 19 EPGP centers in the United States and Australia. Clinical data from medical records, standardized questionnaires, imaging, and EEG were collected with use of online informatics systems developed for EPGP. LGS(u) in the EPGP cohort had a broad range of onset of epilepsy from 1 to 13 years, was male predominant (p < 0.0002), and was associated with normal development prior to seizure onset in 59.2% of patients. Despite the diagnosis, almost half of the adult patients with LGS(u) completed secondary school. Parents were cognitively normal. All subjects had EEG recordings with generalized epileptiform abnormalities with a spike wave frequency range of 1-5 Hz (median 2 Hz), whereas 8.1% of subjects had EEG studies with a normal posterior dominant rhythm. Almost 12% of patients evolved from West syndrome. LGS(u) has distinctive characteristics including a broad age range of onset, male predominance, and often normal development prior to the onset of seizures. Cognitive achievements such as completion of secondary school were possible in half of adult patients. Our phenotypic description of LGS(u) coupled with future genetic studies will advance our understanding of this epilepsy syndrome.

This study aimed to analyze the retention rate of lacosamide (LCM) in patients with epilepsy and intellectual disabilities (IDs), to identify factors influencing retention rate, and to investigate the LCM retention rate with and without concomitant sodium channel blocker (SCB). We hypothesized that the retention rate of LCM with concomitant SCB would be lower than without SCB. Using the Kaplan-Meier estimator, we conducted a monocentric, retrospective, observational, open-label study to evaluate LCM retention rates in patients with IDs and drug-resistant epilepsy. In addition, the impact of therapy-related variables on the long-term retention of LCM was evaluated. One hundred thirty-six subjects with IDs and drug-resistant epilepsy were included (age 2-66 years); most patients had focal epilepsy. Long-term retention rates were 62.0% at 1 year, 43.7% at 2 years, and 29.1% at 3 and 4 years. Reasons for LCM discontinuation included insufficient therapeutic benefits (69%), adverse events (11%), or a combination of both factors (8%). The LCM retention rate was influenced by the number of background antiepileptic drugs (AEDs). An additional and independent influence of concomitant therapy with SCB on retention rate could not be confirmed. One of the major challenges in medically caring for patients with epilepsy and IDs is the high rate of drug resistance. However, there is a lack of evidence-based information about the efficacy and tolerability of AEDs in this population. It has been shown that concomitant SCB use is a key factor in increasing the risk of LCM failure in children with epilepsy. This finding has not been replicated in our predominantly adult sample of patients with IDs. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

Epilepsy surgery in patients with malformations of cortical development.

PubMed

Lüders, Hans; Schuele, Stephan U

2006-04-01

Patients with malformations of cortical development often suffer from intractable focal epilepsy. This review considers recent progress in the selection and seizure outcome of patients undergoing resective epilepsy surgery for this condition. Patients with malformations of cortical development restricted to part or even a whole hemisphere may be candidates for epilepsy surgery even when, due to microscopic malformations, magnetic resonance imaging shows no detectable lesion. Despite recent advances in structural and functional imaging, the majority of patients with this condition undergo invasive evaluation. Patients with focal cortical dysplasia, with and without a detectable lesion on magnetic resonance imaging, often have a favorable outcome with epilepsy surgery. The underlying pathological substrate seems to be a better predictor for surgical outcome in patients with focal cortical dysplasia than the presence of a lesion on magnetic resonance imaging. Epilepsy surgery can be offered in a highly selected subgroup of patients with unilateral nodular heterotopia. Seizures in hemimegalencephaly may respond favorably to hemispherectomy, although most children will continue to have seizures and significant functional impairments. Patients with focal epilepsy due to malformations of cortical development are often intractable to medical management. Resective epilepsy surgery can be beneficial, particularly for patients with focal cortical dysplasia and unilateral hemispheric malformations.

VGKC complex antibodies in epilepsy: diagnostic yield and therapeutic implications.

2013-11-01

In a significant number of patients developing epilepsy in adult life, the aetiology of their seizures remains unclear. Antibodies directed against the voltage gated potassium channel complex (VGKC Ab) have been identified in various cohorts of patients with epilepsy, although the role of these antibodies in epilepsy pathogenesis is not fully known. We reviewed the notes of 144 patients with unexplained adult onset epilepsy who had been tested for VGKC Abs. We collected data on their clinical syndrome, investigation results and response to treatment. We identified 6 (4.2%) patients who had titres of >400 pM. One of the six patients was positive for LGI1 and another for CASPR2 subunit antibodies. All patients were given immunotherapy and experienced improvement in seizure control. No patient had the clinical syndrome of limbic encephalitis. Patients with otherwise unexplained epilepsy and positive VGKC Abs are a heterogeneous group. In our cohort there was an overall favourable response to immunotherapy but further prospective studies are needed to determine the significance of these antibodies and the optimum treatment regimen for patients.

Despite an extensive literature on cognitive impairments in focal and generalized epilepsy, only a few number of studies specifically explored social cognition disorders in epilepsy syndromes. The aim of our study was to investigate social cognition abilities in patients with temporal lobe epilepsy (TLE) and in patients with idiopathic generalized epilepsy (IGE). Thirty-nine patients (21 patients with TLE and 18 patients with IGE) and 21 matched healthy controls (HCs) were recruited. All subjects underwent a basic neuropsychological battery plus two experimental tasks evaluating emotion recognition from facial expression (Ekman-60-Faces test, Ek-60F) and mental state attribution (Story-based Empathy Task, SET). In particular, the latter is a newly developed task that assesses the ability to infer others' intentions (i.e., intention attribution - IA) and emotions (i.e., emotion attribution - EA) compared with a control condition of physical causality (i.e., causal inferences - CI). Compared with HCs, patients with TLE showed significantly lower performances on both social cognition tasks. In particular, all SET subconditions as well as the recognition of negative emotions were significantly impaired in patients with TLE vs. HCs. On the contrary, patients with IGE showed impairments on anger recognition only without any deficit at the SET task. Emotion recognition deficits occur in patients with epilepsy, possibly because of a global disruption of a pathway involving frontal, temporal, and limbic regions. Impairments of mental state attribution specifically characterize the neuropsychological profile of patients with TLE in the context of the in-depth temporal dysfunction typical of such patients. Impairments of socioemotional processing have to be considered as part of the neuropsychological assessment in both TLE and IGE in view of a correct management and for future therapeutic interventions.

The modified Atkins Diet (MAD) is an effective dietary treatment for children with epilepsy. However, adults may have limited access to this therapy because of lack of availability of dietitian or nutrition support or familiarity with the diet by their treating neurologist. This study was designed to investigate the tolerability and efficacy of the MAD administered solely via e-mail to adults with pharmacoresistant epilepsy. A prospective, open-label, proof-of-principle 3-month study design was employed. Adults were enrolled, instructed on how to self-administer a 20 g carbohydrate per day MAD, and followed by the investigators only via e-mail. There were no clinic visits or dietitian contacts during the study period. Twenty-five participants (median age 30 years [range 18-66 years], 68% female) consented and 22 started the MAD. The median prior anticonvulsants was 5 (range 2-10) and seizure frequency was 5 per week (range 1-140). Urinary ketosis was achieved in 21 participants (95%), of which 16 (76%) reported at least 40 mg/dl (moderate). Twenty-one participants (95%) remained on the MAD at 1 month and 14 (64%) at 3 months. After 1 month, 9 (41%) had >50% seizure reduction including one (5%) with >90% seizure reduction using intent-to-treat analysis. After 3 months, 6 (27%) had >50% seizure reduction including 3 (14%) with >90% seizure reduction. The mean ketogenic ratio was 1.1:1 (fat:carbohydrates and protein) for those who provided a MAD food record at follow-up. Over the study period, the median number of e-mails sent by the participants was 6 (range 1-19). The most frequent side effect was weight loss. E-mail administration of the MAD to adults with refractory epilepsy appears to be feasible and effective. Therefore, when dietitian or physician support is limited for adult patients with epilepsy, remote access via telemedicine could provide an alternative.

Copy number variation (CNV) is an important cause of neuropsychiatric disorders. Little is known about the role of CNV in adults with epilepsy and intellectual disability. To evaluate the prevalence of pathogenic CNVs and identify possible candidate CNVs and genes in patients with epilepsy and intellectual disability. In this cross-sectional study, genome-wide microarray was used to evaluate a cohort of 143 adults with unexplained childhood-onset epilepsy and intellectual disability who were recruited from the Toronto Western Hospital epilepsy outpatient clinic from January 1, 2012, through December 31, 2014. The inclusion criteria were (1) pediatric seizure onset with ongoing seizure activity in adulthood, (2) intellectual disability of any degree, and (3) no structural brain abnormalities or metabolic conditions that could explain the seizures. DNA screening was performed using genome-wide microarray platforms. Pathogenicity of CNVs was assessed based on the American College of Medical Genetics guidelines. The Residual Variation Intolerance Score was used to evaluate genes within the identified CNVs that could play a role in each patient's phenotype. Of the 2335 patients, 143 probands were investigated (mean [SD] age, 24.6 [10.8] years; 69 male and 74 female). Twenty-three probands (16.1%) and 4 affected relatives (2.8%) (mean [SD] age, 24.1 [6.1] years; 11 male and 16 female) presented with pathogenic or likely pathogenic CNVs (0.08-18.9 Mb). Five of the 23 probands with positive results (21.7%) had more than 1 CNV reported. Parental testing revealed de novo CNVs in 11 (47.8%), with CNVs inherited from a parent in 4 probands (17.4%). Sixteen of 23 probands (69.6%) presented with previously cataloged human genetic disorders and/or defined CNV hot spots in epilepsy. Eight nonrecurrent rare CNVs that overlapped 1 or more genes associated with intellectual disability, autism, and/or epilepsy were identified: 2p16.1-p15 duplication, 6p25.3-p25.1 duplication, 8p23.3p

The current study examined the relationship between emotional recognition and depression using the Minnesota Multiphasic Personality Inventory, Second Edition (MMPI-2), in a population with epilepsy. Participants were a mixture of surgical candidates in addition to those receiving neuropsychological testing as part of a comprehensive evaluation. Results suggested that patients with epilepsy reporting increased levels of depression (Scale D) performed better than those patients reporting low levels of depression on an index of simple facial recognition, and depression was associated with poor prosody discrimination. Further, it is notable that more than half of the present sample had significantly elevated Scale D scores. The potential effects of a mood-congruent bias and implications for social functioning in depressed patients with epilepsy are discussed.

Introduction Community-based and other epidemiologic studies within the United States have identified substantial disparities in health care among adults with epilepsy. However, few data analyses addressing their health-care access are representative of the entire United States. This study aimed to examine national survey data about adults with epilepsy and to identify barriers to their health care. Materials and methods We analyzed data from U.S. adults in the 2010 and the 2013 National Health Interview Surveys, multistage probability samples with supplemental questions on epilepsy. We defined active epilepsy as a history of physician-diagnosed epilepsy either currently under treatment or accompanied by seizures during the preceding year. We employed SAS-callable SUDAAN software to obtain weighted estimates of population proportions and rate ratios (RRs) adjusted for sex, age, and race/ethnicity. Results Compared to adults reporting no history of epilepsy, adults reporting active epilepsy were significantly more likely to be insured under Medicaid (RR = 3.58) and less likely to have private health insurance (RR = 0.58). Adults with active epilepsy were also less likely to be employed (RR = 0.53) and much more likely to report being disabled (RR = 6.14). They experience greater barriers to health-care access including an inability to afford medication (RR = 2.40), mental health care (RR = 3.23), eyeglasses (RR = 2.36), or dental care (RR = 1.98) and are more likely to report transportation as a barrier to health care (RR = 5.28). Conclusions These reported substantial disparities in, and barriers to, access to health care for adults with active epilepsy are amenable to intervention. PMID:26627980

To describe the diagnostic accuracy of screening questionnaires to identify epilepsy in adults, we performed a systematic review of diagnostic studies that assessed the sensitivity and specificity of such screening questionnaires as compared to a physician's clinical assessment. We searched Ovid MEDLINE (1946 to present) and Ovid EMBASE (1947 to present) for studies that estimated the sensitivity and specificity of nonphysician administered screening questionnaires for adults with epilepsy. Both telephone and in-person administered questionnaires were included, whether applied to population or hospital/clinic-based cohorts. The risk of bias was assessed using the Quality Assessment of Diagnostic Studies-2 (QUADAS-2) tool. Our initial search strategy resulted in 917 records. We found nine studies eligible for inclusion. The estimated sensitivity and specificity of the questionnaires used to identify persons with a lifetime history of epilepsy ranged from 81.5% to 100% and 65.6% to 99.2%, respectively. The sensitivity and specificity of these questionnaires in identifying persons with active epilepsy ranged from 48.6% to 100% and 73.9% to 99.9%, respectively. Overall we found a high risk of bias in patient selection and study flow in the majority of studies. We identified nine validation studies of epilepsy screening questionnaires, summarized their study characteristics, presented their results, and performed a rigorous quality assessment. This review serves as a basis for future studies by providing a systematic review of existing work. Future research addressing previous limitations will ultimately allow us to more accurately estimate the burden and risk of epilepsy in the general population.

Affective temperament profiles and clinical correlates in patients with epilepsy: a link from mood disorders.

PubMed

Erdoğan Taycan, Serap; Taycan, Okan

2014-08-01

The current study sought to investigate the affective temperaments of patients with epilepsy and possible relationships between disease characteristics and temperament profiles. A total of 70 adults with epilepsy and 70 healthy volunteers completed the Beck Depression Inventory (BDI), the Beck Anxiety Inventory and the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A). Patients with epilepsy had higher scores on these three scales than healthy controls. With respect to temperaments, irritable temperament alone was significantly higher in patients than controls. Irritable temperament also had a significant positive correlation with psychiatric history, whereas depressive temperament had a significant positive correlation with illness and treatment duration. Patients who had suffered simple partial and complex partial seizures had higher anxious temperament scores than patients with generalized epilepsy. Because the study group was recruited through consecutive patients seen in a single neurology clinic, our findings may not be representative of PWE in general. Because irritability is one of the key symptoms of interictal dysphoric disorder and because TEMPS-A irritable temperament and BDI scores were found to be significantly related, the high rate of irritable temperament in our patient sample may be associated with depressive mood. We may suggest that at least some of the affective symptoms in patients with epilepsy and the historical concept of "epileptic personality" may be explained by affective temperaments.

Objective: To analyse the long term results of temporal lobe epilepsy surgery in a national epilepsy surgery centre for adults, and to evaluate preoperative factors predicting a good postoperative outcome on long term follow up. Methods: Longitudinal follow up of 140 consecutive adult patients operated on for drug resistant temporal lobe epilepsy. Results: 46% of patients with unilateral temporal lobe epilepsy became seizure-free, 10% had only postoperative auras, and 15% had rare seizures on follow up for (mean (SD)) 5.4 (2.6) years, range 0.25 to 10.5 years. The best outcome was after introduction of a standardised magnetic resonance (MR) imaging protocol (1993–99): in unilateral temporal lobe epilepsy, 52% of patients became seizure-free, 7% had only postoperative auras, and 17% had rare seizures (median follow up 3.8 years, range 0.25 to 6.5 years); in palliative cases (incomplete removal of focus), a reduction in seizures of at least 80% was achieved in 71% of cases (median follow up 3.1 years, range 1.1 to 6.8 years). Most seizure relapses (86%) occurred within one year of the operation, and outcome at one year did not differ from the long term outcome. Unilateral hippocampal atrophy with or without temporal cortical atrophy on qualitative MR imaging (p < 0.001, odds ratio (OR) 5.2, 95% confidence interval (CI) 2.0 to 13.7), other unitemporal structural lesions on qualitative MR imaging (p ≤ 0.001, OR 6.9, 95% CI 2.2 to 21.5), onset of epilepsy before the age of five years (p < 0.05, OR 2.9, 95% CI 1.2 to 7.2), and focal seizures with ictal impairment of consciousness and focal ictal EEG as a predominant seizure type (p < 0.05, OR 3.4, 95% CI 1.2 to 9.1) predicted Engel I–II outcome. Hippocampal volume reduction of at least 1 SD from the mean of controls on the side of the seizure onset (p < 0.05, OR 3.1, 95% CI 1.1 to 9.2) also predicted Engel I–II outcome. Conclusions: Outcome at one year postoperatively is highly predictive of long term outcome

SUMMARY Objective To examine mortality and causes of death (COD) in socioeconomically disadvantaged persons with epilepsy (PWE) in the US. Methods We performed a retrospective open cohort analysis using Ohio Medicaid claims data between 1992 and 2008 to assess mortality and COD in 68,785 adult Medicaid beneficiaries with epilepsy. Case fatality (CF), mortality rates (MRs), standardized mortality ratios (SMRs), and years of potential life lost (YPLL) were calculated. The SMRs were estimated to compare risk of death in PWE with that in the general Medicaid population with and without disabilities. Proportionate mortality ratios (PMRs), YPLLs, and SMRs for specific COD were also obtained. Results There were 12,630 deaths in PWE. CF was 18.4%, the age-race-sex adjusted MR was 18.6/1,000 person-years (95% CI, 18.3–18.9). The SMR was 1.8 (95% CI, 1.8 – 1.9) when compared to the general Medicaid population, and was 1.4 (95% CI, 1.3–1.6) when compared to those with disabilities. The average YPLL was 16.9 years (range, 1–47 years). Both epilepsy and comorbid conditions significantly contributed to premature mortality in PWE. Cardiovascular diseases, cancer, and unintentional injuries were the most common COD and account for a large proportion of YPLL. Deaths from epilepsy-related causes occurred in about 10% of the cases. Significance Socioeconomically deprived PWE, especially young adults, experience high mortality and die 17 years prematurely. The high mortality in Medicaid beneficiaries with epilepsy affirms that comorbid conditions and epilepsy play a crucial role in premature death. Management of comorbid conditions is, at a minimum, as important as epilepsy management, and therefore deserves more attention from physicians, particularly those who care for Medicaid individuals with epilepsy.

The objective of this (trial-based) economic evaluation was, from a societal perspective, to compare the cost-effectiveness of a multicomponent self-management intervention (MCI) with care as usual (CAU) in adult patients with epilepsy over a 12-month period. In a randomized-controlled trial, participants were randomized into intervention or CAU group. Adherence, self-efficacy (Epilepsy Self-Efficacy Scale [ESES]), quality-adjusted life years (QALYs), healthcare costs, production losses, and patient and family costs were assessed at baseline and during the 12-month study period. Incremental cost-effectiveness ratios (ICERs) (i.e., cost per increased adherence, self-efficacy, or QALY), and cost-effectiveness acceptability curves were calculated. In total, 102 patients were included in the study, of whom 52 were in the intervention group. Adherence rates over 6 months were 63.7% for the CAU group and 75.9% for the intervention group. Adherence, ESES, and quality of life did not differ significantly between groups. An ICER of €54 per point increase in ESES score at 6 months and €1,105 per point increase at 12-month follow-up was found. The intervention resulted in an ICER of €88 per percentage of adherence increase at 6 months. ICERs of €8,272 and €15,144 per QALY gained were found at 6- and 12-month follow-up, respectively. Although no statistically significant difference was found after baseline adjustments, cost-effectiveness estimates for MCI appear promising. As rules of inference are arbitrary, it has been argued that decisions should be based only on the net benefits, irrespective of whether differences are statistically significant. Hence, the MCI may be a cost-effective addition to the current standard care for adults with epilepsy. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

Neurocysticercosis (NCC), a neglected tropical disease, inflicts substantial health and economic costs on people living in endemic areas such as India. Nevertheless, accurate diagnosis using brain imaging remains poorly accessible and too costly in endemic countries. The goal of this study was to test if blood monocyte gene expression could distinguish patients with NCC-associated epilepsy, from NCC-negative imaging lesion-free patients presenting with idiopathic epilepsy or idiopathic headaches. Patients aged 18 to 51 were recruited from the Department of Neurological Sciences, Christian Medical College and Hospital, Vellore, India, between January 2013 and October 2014. mRNA from CD14+ blood monocytes was isolated from 76 patients with NCC, 10 Recovered NCC (RNCC), 29 idiopathic epilepsy and 17 idiopathic headaches patients. A preliminary microarray analysis was performed on six NCC, six idiopathic epilepsy and four idiopathic headaches patients to identify genes differentially expressed in NCC-associated epilepsy compared with other groups. This analysis identified 1411 upregulated and 733 downregulated genes in patients with NCC compared to Idiopathic Epilepsy. Fifteen genes up-regulated in NCC patients compared with other groups were selected based on possible relevance to NCC, and analyzed by qPCR in all patients' samples. Differential gene expression among patients was assessed using linear regression models. qPCR analysis of 15 selected genes showed generally higher gene expression among NCC patients, followed by RNCC, idiopathic headaches and Idiopathic Epilepsy. Gene expression was also generally higher among NCC patients with single cyst granulomas, followed by mixed lesions and single calcifications. Expression of certain genes in blood monocytes can distinguish patients with NCC-related epilepsy from patients with active Idiopathic Epilepsy and idiopathic headaches. These findings are significant because they may lead to the development of new tools to

Case management (CM) has been shown to improve the medical care of patients in several paradigms of general medicine. This study was undertaken to assess the impact of CM on low-income patients with epilepsy. From 2002 to 2003, 737 epilepsy patients had CM provided by a non-profit, state-supported, epilepsy service subserving a four county region in southeastern Florida. Standardized survey forms distributed by the Florida Department of Health were completed by 159 consecutive patients at program admission. Follow-up information regarding seizure frequency, antiepileptic drugs, and quality of life self-rating was performed after 1 year of CM. The patients evaluated were composed of 58.5% men, with a mean age of 41.0 years. After CM, an increase in self-reported seizure control was seen in 40.2% of patients (p<0.0001, Fisher's exact test), in addition to a shift in the principal utilization of the older to the newer antiepileptic drugs. Furthermore, the total number of emergency department (ED) visits was reduced by 90% with a mean reduction of ED visits per patient from 1.83 per patient per year before CM to 0.14 per patient per year after CM (p<0.0001, Wilcoxon matched-pairs test). Following CM, fewer patients reported difficulty with friends, employers, problems socializing, and feelings of anger (p<0.05, Fisher's exact test). CM of low-income patients with epilepsy resulted in self-reported improvement in seizure control, QoL, and significantly reduced ED visitation. CM in epilepsy is feasible and represents a cost-effective improvement in outpatient epilepsy management.

This study evaluated trends in the resource use of patients with active epilepsy over a 5-year period at an outpatient clinic of a German epilepsy center. Two cross-sectional cohorts of consecutive adults with active epilepsy were evaluated over a 3-month period in 2003 and 2008. Data on socioeconomic status, course of epilepsy, as well as direct and indirect costs were recorded using validated patient questionnaires. We enrolled 101 patients in 2003 and 151 patients in 2008. In both cohorts, 76% of the patients suffered from focal epilepsy, and the majority was on antiepileptic drug (AED) polytherapy (mean AED number: 1.7 (2003), 1.8 (2008)). We calculated epilepsy-specific costs of € 2955 in 2003 and € 3532 in 2008 per 3 months per patient. Direct medical costs were mainly due to anticonvulsants in 2003 (59.4% of total direct costs, 34.0% in 2008) and to hospitalization in 2008 (46.9% of total direct costs, 27.7% in 2003). The proportion of enzyme-inducing anticonvulsants and 'old' AEDs decreased between 2003 and 2008. Indirect costs of € 1689 and € 1847 were mainly due to early retirement (48.4%; 46.0% of total indirect costs in 2003; 2008), unemployment (26.1%; 24.2%), and days off due to seizures (25.5%; 29.8%). This study showed a shift in distribution of direct cost components with increased hospital costs as well as a cost-neutral increase in the prescription of 'newer' AEDs. The amount and distribution of indirect cost components remained unchanged. Copyright © 2013 Elsevier Inc. All rights reserved.

To obtain perspective on epilepsy in patients referred to tertiary centers in France, and describe etiology, epilepsy syndromes, and identify factors of drug resistance and comorbidities. We performed a cross-sectional analysis of the characteristics of 5,794 pediatric and adult patients with epilepsy included in a collaborative database in France between 2007 and 2013. Comparisons between groups used Student's t-test or Fisher's exact test for binary or categorical variables. Factors associated with drug resistance and intellectual disability were evaluated in multi-adjusted logistic regression models. Mean age at inclusion was 17.9 years; children accounted for 67%. Epilepsy was unclassified in 20% of patients, and etiology was unknown in 65%, including those with idiopathic epilepsies. Etiologies differed significantly in adult- when compared to pediatric-onset epilepsy; however, among focal structural epilepsies, mesial temporal lobe epilepsy with hippocampal sclerosis began as often in the pediatric as in adult age range. Drug resistance concerned 53% of 4,210 patients evaluable for seizure control and was highest in progressive myoclonic epilepsy (89%), metabolic diseases (84%), focal cortical dysplasia (70%), other cortical malformations (69%), and mesial temporal lobe epilepsy with hippocampal sclerosis (67%). Fifty-nine percent of patients with focal structural epilepsy and 69% with epileptic encephalopathies were drug resistant; however, 40-50% of patients with West syndrome and epileptic encephalopathy with continuous spike-and-waves during sleep were seizure-free. Ages at onset in infancy and in young adults shared the highest risk of drug resistance. Epilepsy onset in infancy comprised the highest risk of intellectual disability, whereas specific cognitive impairment affected 36% of children with idiopathic focal epilepsy. Our study provides a snapshot on epilepsy in patients referred to tertiary centers and discloses needs for diagnosis and treatment

Epilepsy, a brain disorder leading to recurring seizures, has garnered increased public health focus because persons with epilepsy experience pronounced and persistent health and socioeconomic disparities despite treatment advances, public awareness programs, and expanded rights for persons with disabilities (1,2). For almost all states, epilepsy prevalence estimates do not exist. CDC used national data sources including the 2015 National Health Interview Survey (NHIS) for adults (aged ≥18 years), the 2011-2012 National Survey of Children's Health (NSCH), and the 2015 Current Population Survey data, describing 2014 income levels, to estimate prevalent cases of active epilepsy, overall and by state, to provide information for state public health planning. In 2015, 1.2% of the U.S. population (3.4 million persons: 3 million adults and 470,000 children) reported active epilepsy (self-reported doctor-diagnosed epilepsy and under treatment or with recent seizures within 12 months of interview) or current epilepsy (parent-reported doctor-diagnosed epilepsy and current epilepsy). Estimated numbers of persons with active epilepsy, after accounting for income and age differences by state, ranged from 5,900 in Wyoming to 427,700 in California. NHIS data from 2010-2015 indicate increases in the number of persons with active epilepsy, probably because of population growth. This study provides updated national and modeled state-specific numbers of active epilepsy cases. Public health practitioners, health care providers, policy makers, epilepsy researchers, and other epilepsy stakeholders, including family members and people with epilepsy, can use these findings to ensure that evidence-based programs meet the complex needs of adults and children with epilepsy and reduce the disparities resulting from it.

Risk factors for fatigue in patients with epilepsy.

2016-11-01

Fatigue is highly prevalent in patients with epilepsy and has a major impact on quality of life, but little data is available on its effects and management in epilepsy. To identify the incidence and risk factors of fatigue in patients with epilepsy, 105 epilepsy patients (45 women and 60 men) were enrolled in our study. Demographic and clinical data were collected and psychological variables including fatigue, sleep quality, excess daytime sleepiness, anxiety, and depression were measured by Fatigue Severity Scale, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and Hospital Anxiety and Depression Scale, respectively. Of 105 patients, 29.5% exhibited fatigue (FSS score ⩾4). We found no correlation between the occurrence of fatigue and any of our demographic or clinical variables. Fatigue is correlated with low sleep quality, anxiety, and depression, but not with excess daytime sleepiness. Thus, we concluded that fatigue is highly prevalent in patients with epilepsy, and that low sleep quality, anxiety, and depression are significantly correlated with fatigue in epileptics, while excess daytime sleepiness not.

It has been reported that epilepsy patients had higher risk of sudden death than that of the general population. However, in Japan, there is very little literature on the observational research conducted on sudden fatal events in epilepsy. We performed a single-center, retrospective study on all the out-of-hospital cardiac arrest (OHCA) patients treated in our emergency department between 2007 and 2013. Among the OHCA patients, we extracted those with a history of epilepsy and then analyzed the characteristics of the fatal events and the background of epilepsy. From 1,823 OHCA patients, a total of 10 cases were enrolled in our study. The median age was 34 years at the time of the incident [9-52 years; interquartile range (IQR), 24-45]. We determined that half of our cases resulted from external causes of death such as drowning and suffocation and the other half were classified as sudden unexpected death in epilepsy (SUDEP). In addition, asphyxia was implicated as the cause in eight cases. Only the two near-drowning patients were immediately resuscitated, but the remaining eight patients died. The median age of first onset of epilepsy was 12 years (0.5-30; IQR, 3-21), and the median disease duration was 25 years (4-38; IQR, 6-32). Patients with active epilepsy accounted for half of our series and they were undergoing poly anti-epileptic drug therapy. The fatal events related to epilepsy tended to occur in the younger adult by external causes. An appropriate therapeutic intervention and a thorough observation were needed for its prevention.

Clinic-Based Mobile Health Decision Support to Enhance Adult Epilepsy Self-Management: An Intervention Mapping Approach.

PubMed

Shegog, Ross; Begley, Charles E

2017-01-01

Epilepsy is a neurological disorder involving recurrent seizures. It affects approximately 5 million people in the U.S. To optimize their quality of life people with epilepsy are encouraged to engage in self-management (S-M) behaviors. These include managing their treatment (e.g., adhering to anti-seizure medication and clinical visit schedules), managing their seizures (e.g., responding to seizure episodes), managing their safety (e.g., monitoring and avoiding environmental seizure triggers), and managing their co-morbid conditions (e.g., anxiety, depression). The clinic-based Management Information Decision Support Epilepsy Tool (MINDSET) is a decision-support system founded on theory and empirical evidence. It is designed to increase awareness by adult patients (≥18 years) and their health-care provider regarding the patient's epilepsy S-M behaviors, facilitate communication during the clinic visit to prioritize S-M goals and strategies commensurate with the patient's needs, and increase the patient's self-efficacy to achieve those goals. The purpose of this paper is to describe the application of intervention mapping (IM) to develop, implement, and formatively evaluate the clinic-based MINDSET prototype and in developing implementation and evaluation plans. Deliverables comprised a logic model of the problem (IM Step 1); matrices of program objectives (IM Step 2); a program planning document comprising scope, sequence, theory-based methods, and practical strategies (IM Step 3); a functional MINDSET program prototype (IM Step 4); plans for implementation (IM Step 5); and evaluation (IM Step 6). IM provided a logical and systematic approach to developing and evaluating clinic-based decision support toward epilepsy S-M.

To investigate whether addition of antipsychotic drugs (APD) would increase seizure frequency in epilepsy patients who were already treated with anti-epileptic drugs (AED), we compared a one-year seizure control outcome in 150 epilepsy patients with APD treatment for psychiatric conditions and 309 epilepsy patients without APD treatment matched for ages at epilepsy onset and the baseline evaluation and types of epilepsy. The seizure frequency was recorded at the baseline (immediately before the start of APD) and after the 1st, 3rd, 6th and 12th months. The seizure outcome at each of the four follow-up points was compared with the baseline. The seizure outcome was compared between the two groups as a whole and according to the types of epilepsy (idiopathic generalized and partial epilepsies). In the APD group, the seizure outcome was also analyzed according to the types of APD (first and second generation APD and combination of first and second generation APD) and the types of psychiatric conditions (psychosis and non-psychosis). The seizure outcome was significantly better in the APD group than control group at all the four follow-up points. According to the epilepsy types, the improvement in the seizure outcome was only observed in the patients with partial epilepsy. Of the APD group, there was no significant difference in the seizure outcome according to the types of APD or the psychiatric conditions. In epilepsy patients who are already treated with AED, APD treatment seems safe in seizure control outcome for treatment of psychiatric conditions. Copyright © 2014 Elsevier B.V. and ECNP.

Hansen, Barbara; Szaflarski, Magdalena; Bebin, E Martina; Szaflarski, Jerzy P

2018-06-07

Intractable epilepsy can be challenging for patients and for their families. Disability rates in patients are high, causing tremendous physical and emotional burden on family caregivers. Additionally, caregivers may experience affiliate stigma, where they perceive and internalize the negative societal views of a condition and exhibit a psychological response. Affiliate stigma has been rarely studied in caregivers of those with intractable epilepsy. This study examined the relationship between affiliate stigma and the levels of burden experienced by caregivers, as well as how these levels may vary between those caring for children and adults. This cross-sectional approach used a self-administered survey offered to caregivers of family members with confirmed diagnoses of intractable epilepsy. We measured burden with the 30-item Carer's Assessment of Difficulties Index (CADI) and affiliate stigma with a six-item scale examining caregivers' perceptions of stigma directed toward themselves and their family members with epilepsy. Four nested ordinary-least-squares regression models were estimated using stigma scale scores to predict levels of perceived burden adjusting for demographic variables. Age of the patient with epilepsy was dichotomized (pediatric/adult) to assess a possible moderating effect of patient's age on the relationship between stigma and caregiver burden. Respondents (N = 136) were predominantly White (83%), female (75%), and married (69%), with an average age of 43 years. Patients with epilepsy were 52% male with ages ranging from 2 to 82 years. Each of the regression models yielded positive associations (p < 0.001) between perceived levels of caregiver burden and affiliate stigma. Additionally, the age of the family member with epilepsy moderated (p < 0.05) the effect, with the relationship stronger for caregivers of adults. In a highly select group of patients with refractory epilepsy recruited mostly from a cannabidiol (CBD) clinic

Caring for transgender patients with epilepsy.

Johnson, Emily L; Kaplan, Peter W

Approximately 25 million individuals older than age 15 identify as transgender, representing about 0.3-0.9% of the world's population. The aim of this paper is to identify and describe important medical and social considerations facing transgender persons with epilepsy. We performed literature searches on the following terms: transgender AND epilepsy, transgender AND neurology, gender dysphoria AND epilepsy, gender dysphoria AND neurology. We also performed literature searches for common feminizing or masculinizing treatment regimens, and searched for interactions of those treatment regimens with antiepileptic drugs (AEDs) and with seizures. There are multiple bidirectional interactions between AEDs and the commonly used treatments for aligning external sex characteristics with identified gender. The scope of the transgender population with epilepsy remains to be elucidated. Transgender patients with epilepsy face significant social and medical challenges. Interactions between medical gender-affirming treatments and AEDs are common, and management must depend on knowledge of these interactions to provide appropriate treatment.

People with epilepsy are at increased risk of premature death compared with the general population. Many clinicians are unsure whether and when this issue should be broached with their patients. We analysed mortality in patients with newly diagnosed and chronic epilepsy over a 20-year period. Patients who attended the epilepsy service at the Western Infirmary in Glasgow, UK between 1981 and 2001, with newly diagnosed epilepsy (n=890) or referred after receiving unsuccessful treatment elsewhere (n=2689) were included in the study. Mortality data were obtained from the General Registrar Office for Scotland. Causes of death were ascertained from death certificates and primary care and health authority records. The two patient cohorts were compared with age-matched and sex-matched Scottish comparison groups. Standardised mortality ratios (SMR) were calculated for each epilepsy type, 10-year age band, and cause of death category. Newly diagnosed patients had a 42% increase in mortality (SMR 1.42, 95% CI 1.16-1.72) compared with the comparison group. Increased mortality was recorded in those who had not responded to treatment, with no increase in risk observed in patients who were seizure free. In the chronic epilepsy cohort, there was more than double the expected number of deaths (2.05, 1.83-2.26). The incidence of sudden unexpected death in epilepsy was 1.08 and 2.46 per 1000 patient-years in patients with newly diagnosed and chronic epilepsy, respectively. The greatest excess in mortality was reported in patients younger than 30 years. Mortality risks and preventive strategies should be discussed with patients with epilepsy when treatment fails or is refused despite recurrent seizures.

Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy. Focal cortical dysplasia is the most common dual pathology found in association with the hippocampal sclerosis. In this study, the effect of dual pathology on freedom from seizure was sought in patients with TLE. This study performed a retrospective analysis of patients with TLE who underwent surgery between 2010 and 2017. Histopathologic analysis was performed on patients with and without dual pathology in the temporal neocortex. Seizure outcomes were compared. A total of 54 patients with TLE were included. The rate of overall favorable seizure outcome was found to be 96.3%. In 53.7%, dual pathology was present in the temporal cortices in addition to the hippocampal sclerosis. Patients without dual pathology showed significantly greater freedom from seizure (P = 0.02). Patients without dual pathology had a significantly higher seizure-free rate after anterior temporal resection than patients with dual pathology. Resection of the temporal cortex in addition to mesial temporal structures seems to be reasonable for better seizure outcome. Copyright © 2018 Elsevier Inc. All rights reserved.

The incidence of psychogenic non-epileptic seizures (PNES) is 4.9/100,000/year and it is estimated that about 20-30% of patients referred to tertiary care epilepsy centers for refractory seizures have both epilepsy and PNES. The purpose of our study is to evaluate psychiatric disorders and neuropsychological functions among patients with PNES, patients with epilepsy associated with PNES and patients with epilepsy. We evaluated 66 consecutive in-patients with video-EEG recordings: 21 patients with epilepsy, 22 patients with PNES and 10 patients with epilepsy associated with PNES; 13 patients were excluded (8 because of mental retardation and 5 because they did not present seizures or PNES during the recording period). All patients with PNES had a psychiatric diagnosis (100%) vs. 52% of patients with epilepsy. Cluster B personality disorders were more common in patients with PNES. We observed fewer mood and anxiety disorders in patients with PNES compared with those with epilepsy. We did not find statistically significant differences in neuropsychological profiles among the 3 patient groups. This study can help to contribute to a better understanding of the impact of PNES manifestations, in addition to the occurrence of seizures, in order to provide patients with more appropriate clinical, psychological and social care.

Adult patients with refractory epilepsy who are potential candidates for resective surgery undergo a period of presurgical investigation in tertiary epilepsy centers (TECs), where they engage extensively with healthcare professionals and receive a range of treatment-related information. This qualitative study aimed to examine the experiences of adult patients with refractory epilepsy leading up to and during presurgical investigation and how their perceptions of resective surgery are shaped. In-depth interviews with 12 patients and six epilepsy specialist clinicians and 12 observations of routine patient-clinician consultations took place at two TECs in Sydney, Australia. Data were thematically analyzed via group work. Patients reflected on prior experiences of poor seizure control and inadequate antiepileptic drug management and a lack of clarity about their condition before referral to tertiary care. Poor continuity of care and disrupted care transitions affected patients from regional locations. Tertiary referral increased engagement with personalized information about refractory epilepsy, which intensified during presurgical assessments with additional hospital visits and consultations. Experiential information, such as testimonials of other patients, influenced perceptions of surgery and fostered more trust and confidence towards healthcare professionals. Qualitative inquiry detailed multifaceted effects of information on patients' overall treatment trajectory and experience of healthcare. Earlier patient identification for surgical assessments should be accompanied by access to good quality information at primary and community care levels and strengthened referral processes.

In newly diagnosed patients with Dravet syndrome sodium channel blockers are usually avoided. However, in many adult patients the diagnosis was made long after the initiation of therapy. The purpose of our study was to acquire information concerning the potential risks and benefits of (ox)carba(ma)zepine withdrawal in adult patients with genetically confirmed Dravet syndrome. We identified 16 adults with Dravet syndrome, living in a tertiary care facility for people with epilepsy and an intellectual disability. We reviewed clinical history, genetic findings, the type and duration of sodium channels blockers that were used, seizure types and frequency, and the effect of a change in these medications. The study population consisted of 9 men and 7 women. Median age was 35 years (range 20-61 years). An attempt to withdraw carbamazepine (CBZ) was made in 9 patients. In 3 of these patients an increase in tonic-clonic seizures was observed. An attempt to withdraw oxcarbazepine (OXC) was made in 3 patients, leading to a complete stop in 2 patients. 3 of the 4 deaths in the withdrawal-group were related to epilepsy. In adult patients with Dravet syndrome withdrawal of CBZ or OXC is not without risks. We suggest that (ox)carba(ma)zepine withdrawal should be considered in these patients but only if there is a good reason to do so and only if they are closely monitored.

People with epilepsy are at increased risk of accidents and injuries but, despite several studies on this subject, data regarding preventable causes are still contradictory. The aim of this study was to investigate the relationship between injuries, side effects of antiepileptic drugs (AEDs) and depression. Data from a consecutive sample of adult patients with epilepsy attending the outpatient clinics at St George's University Hospital in London were included. All patients were asked if they had had any injury since the last clinic appointment and completed the Liverpool Adverse Event Profile (LAEP) and Neurological Disorders Depression Inventory for Epilepsy. Among 407 patients (243 females, mean age 43.1 years), 71 (17.4%) reported injuries since the last appointment. A two-step cluster analysis revealed two clusters with the major cluster (53.5% of the injured group) showing a total score for LAEP ≥45, a positive Neurological Disorders Depression Inventory for Epilepsy screening and presence of AED polytherapy. A total score for LAEP ≥45 was the most important predictor. Antiepileptic drug treatment should be reviewed in patients reporting injuries in order to evaluate the potential contribution and burden of AED side effects. © 2017 EAN.

Children with benign epilepsy with centrotemporal spikes (BECTS) have traditionally been considered to have a uniformly good prognosis. However, benign may be a misnomer because BECTS is linked to cognitive deficits, a more severe phenotype with intractable seizures, and the potential for sudden unexpected death in epilepsy (SUDEP). To determine if cases of BECTS are present in the North American SUDEP Registry (NASR). The NASR is a clinical and biospecimen repository established in 2011 to promote SUDEP research. The NASR database, which includes medical records, results of electroencephalographic tests, and interviews with family members of patients with epilepsy who died suddenly without other identifiable causes of death, was queried from June 3, 2011, to June 3, 2016, for cases of BECTS. The patients with epilepsy had died suddenly without other identifiable causes of death (eg, drowning, trauma, exposure to toxic substances, or suicide); SUDEP classification was determined by the consensus of 2 epileptologists. Cases of SUDEP among children who received a diagnosis of BECTS among patients reported in the NASR. Three boys (median age at death, 12 years; range, 9-13 years) who received a diagnosis of BECTS by their pediatric epileptologist or neurologists were identified among 189 cases reported in the NASR. The median age of epilepsy onset was 5 years (range, 3-11 years), and the median duration of epilepsy was 4 years (range, 1-10 years). Two deaths were definite SUDEP, and 1 was probable SUDEP. Independent review of clinical and electroencephalographic data supported the diagnosis of BECTS in all 3 patients. None of the patients was prescribed antiseizure drugs, either owing to physician recommendation or mutual decision by the physician and parents. All 3 patients were found dead in circumstances typical of SUDEP. The 3 patients spanned the spectrum of BECTS severity: 1 had only a few seizures, 1 had more than 30 focal motor seizures, and 1 had 4 witnessed

Infection with the human immunodeficiency virus (HIV) is associated both with infections of the central nervous system and with neurological deficits due to direct effects of the neurotropic virus. Seizures and epilepsy are not rare among HIV-infected patients. We investigated the frequency of acute seizures and epilepsy of patients in different stages of HIV infection. In addition, we compared the characteristics of patients who experienced provoked seizures only with those of patients who developed epilepsy. The database of the Department of Neurology, University of Münster, was searched for patients with HIV infection admitted between 1992 and 2004. Their charts were reviewed regarding all available sociodemographic, clinical, neurophysiological, imaging and laboratory data, therapy and outcome. Stage of infection according to the CDC classification and the epileptogenic zone were determined. Of 831 HIV-infected patients treated in our department, 51 (6.1%) had seizures or epilepsy. Three of the 51 patients (6%) were diagnosed with epilepsy before the onset of the HIV infection. Fourteen patients (27%) only had single or few provoked seizures in the setting of acute cerebral disorders (eight patients), drug withdrawal or sleep withdrawal (two patients), or of unknown cause (four patients). Thirty-four patients (67%) developed epilepsy in the course of their HIV infection. Toxoplasmosis (seven patients), progressive multifocal leukencephalopathy (seven patients) and other acute or subacute cerebral infections (five patients) were the most frequent causes of seizures. EEG data of 38 patients were available. EEG showed generalized and diffuse slowing only in 9 patients, regional slowing in 14 patients and regional slowing and epileptiform discharges in 1 patient. Only 14 of the patients had normal EEG. At the last contact, the majority of the patients (46 patients=90%) were on highly active antiretroviral therapy (HAART). Twenty-seven patients (53%) were on

As surgical treatments for adult and pediatric forms of epilepsy have become more refined, methods for noninvasive localization of epileptogenic foci have become increasingly important. Detection of focal brain metabolic or flow abnormalities is now well recognized as an essential step in the presurgical evaluation of many patients with epilepsy. Positron emission tomography (PET) scanning is most beneficial when used in the context of the total clinical evaluation of patients, including scalp EEG, invasive EEG, neuropsychologic testing, etc. Metabolic PET studies also give insight into pathophysiologic mechanisms of epilepsy. The dynamic nature of the interictal hypometabolism observed with 18(F)FDG inmore » some patients suggests that excitatory or inhibitory neurotransmitters and their receptors may be involved. An exciting current application of PET scanning is the use of tracers for neurotransmitter receptors in the study of epilepsy patients. Mu and non-mu opiate receptors have been extensively studied and are beginning to give new insights into this disorder. Increased labeling of mu receptors in temporal neocortex using 11C-carfentanil has been demonstrated and, in some patients, supplements the clinical localization information from 18(F)FDG studies. Increased mu opiate receptor number or affinity is thought to play a role in anticonvulsant mechanisms. Specificity of increased mu receptors is supported by the absence of significant changes in non-mu opiate receptors. Other brain receptors are also of interest for future studies, particularly those for excitatory neurotransmitters. Combined studies of flow, metabolism, and neuroreceptors may elucidate the factors responsible for initiation and termination of seizures, thus improving patient treatment.95 references.« less

Background and aim Adherence to treatment is a critical component of epilepsy management. This study examines whether addressing antiepileptic drug (AED) side effects at every visit is associated with increased patient-reported medication adherence. Patients and methods This study identified 243 adults with epilepsy who were seen at two academic outpatient neurology settings and had at least two visits over a 3-year period. Demographic and clinical characteristics were abstracted. Evidence that AED side effects were addressed was measured through 1) phone interview (patient-reported) and 2) medical records abstraction (physician-documented). Medication adherence was assessed using the validated Morisky Medication Adherence Scale-4. Complete adherence was determined as answering “no” to all questions. Results Sixty-two (25%) patients completed the interviews. Participants and nonparticipants were comparable with respect to demographic and clinical characteristics; however, a smaller proportion of participants had a history of drug-resistant epilepsy than nonparticipants (17.7% vs 30.9%, P=0.04). Among the participants, evidence that AED side effects were addressed was present in 48 (77%) medical records and reported by 51 (82%) patients. Twenty-eight (45%) patients reported complete medication adherence. The most common reason for incomplete adherence was missed medication due to forgetfulness (n=31, 91%). There was no association between addressing AED side effects (neither physician-documented nor patient-reported) and complete medication adherence (P=0.22 and 0.20). Discussion and conclusion Among patients with epilepsy, addressing medication side effects at every visit does not appear to increase patient-reported medication adherence. PMID:27826186

To evaluate the anticonvulsant effect of the novel high definition transcranial direct current stimulation (HD-tDCS) method on patients with refractory lateral frontal lobe epilepsy. The effects of HD-tDCS on working memory were also examined. 10 adult patients with intractable lateral frontal lobe epilepsy were studied. A central cathode electrode was placed on the epileptogenic zone according to LTM, and 20-min sessions of 2mA HD-tDCS were applied for 10 consecutive days. The primary endpoint was to make changes in the epileptiform discharges (EDs) during a 1-h EEG. Moreover, the seizure frequency based on seizure diary and neuropsychiatric parameters was evaluated. All patients tolerated HD-tDCS stimulation course without any adverse reaction. The frequency of EDs increased immediately and one month after the stimulation course by an average of 6.4% and 1.2%, respectively. However, these changes in the EDs frequency were not statistically significant (p-value >0.05). The mean seizure frequency changes showed decrement by an average of 17.9% immediately, and increment by an average of 38.1% one month after the HD-tDCS. These changes were not significant statistically (p-value >0.05). One patient experienced exacerbation of seizures during the stimulations hence dropped out of the study. Attention and working memory improved significantly immediately and one month after the HD-tDCS in all patients. Changes of EDs and mean seizure frequency caused by HD-tDCS were not statistically significant for the whole group; however, this method could improve the patients' working memory scores.

We combined 2010 and 2013 National Health Interview Survey (NHIS) data to examine the prevalence of seeing a neurologist/epilepsy specialist and/or a general doctor among US adults with active epilepsy who either took antiseizure medications or had at least one seizure in the past 12months. Among adults with recent seizures, about 76% of adults who did not take antiseizure medication (including 55% of those who saw only a general doctor and 21% of those who saw neither a specialist nor a general doctor) and 26% of those who took medication (including 23% of those who saw only a general doctor and 3% of those who saw neither a specialist nor a general doctor) had not seen a specialist within the past year-indicating gaps in quality care putting patients with uncontrolled seizures at risk of negative outcomes. The US Healthy People 2020 objectives call for increasing the proportion of people with epilepsy and uncontrolled seizures who receive appropriate medical care. Epilepsy stakeholders can work with community services/organizations to improve provider education about epilepsy, eliminate barriers to specialized care, and promote self-management support to reduce the burden of uncontrolled seizures in people with epilepsy.

Describe the characteristics of persons with epilepsy (PWEs) and caregivers that have or have not heard of sudden unexpected death in epilepsy (SUDEP) prior to completing a survey through the Internet or in the clinical setting. An online survey for adult PWEs and caregivers was solicited by e-mail and newsletter to Epilepsy Therapy Project members. A similar survey was implemented in a clinic setting of a community hospital. The survey asked about seizure characteristics, epilepsy management, fear of death, and familiarity with the term SUDEP. Respondents that never heard of SUDEP read a definition and responded to questions about their initial reactions. Surveys from 1,392 PWEs and 611 caregivers recruited through an epilepsy Website and a clinic demonstrated that Internet respondents were much more likely to have heard about SUDEP than the clinic population (71.1% vs. 38.8%; p < 0.001), and caregivers of PWEs were more likely to have heard about SUDEP than PWEs (76.2% vs. 65.2%; p < 0.001). Prior awareness was related to an increased level of education, more severe and longer duration of epilepsy, and having an epileptologist as the primary care provider. Although most PWEs and caregivers reported feelings of fear, anxiety, and sadness after first hearing of SUDEP, they wanted to discuss it with their doctor. Persons with epilepsy, and especially their caregivers, often worry that the PWEs may die of epilepsy or seizures. This worry escalated with knowledge of SUDEP and increased epilepsy severity. Approximately half of PWEs and caregivers believed that knowledge about SUDEP would influence their epilepsy management. Our results may help epilepsy care providers determine when to facilitate a discussion about epilepsy-related mortality and SUDEP among patients and caregivers, and to educate those at high risk about the importance of seizure control as well as reduce fears about death in patients with well-controlled and nonconvulsive epilepsies.

The incidences of seizures and epilepsy in the population show a peak after 60 years of age. Due to the lack of reported clinical aspects of seizure and epilepsy in the older patients in our region in Iran, this study was conducted to describe the clinical manifestation, etiology, differential diagnosis, and epilepsy subtypes of epilepsy and seizure. A cross-sectional retrospective study was performed on all consecutively elderly seizure and epilepsy patients, referred to the Epilepsy Association in the city of Qom, Iran over a 10-year period. A total of 466 patients aged >60 years were admitted. 31 % of the patients had epilepsy or seizure and 69 % of them had non-epileptic events. The most prevalent differential diagnoses in the beginning were syncope and cardiovascular disorders. The most frequent clinical symptom of epilepsy was generalized tonic-clonic seizures (75 %). The most common cause of seizure was systemic metabolic disorder (27 %). In epileptic elderly patients, no cause was ascertained for 38 % and the most frequently observed pathological factors were cerebrovascular diseases, which accounted for 24 %. The most common type of epileptic seizure was generalized epileptic seizures (75 %). 10 % of elderly epileptic patients suffered from status epilepticus, which was primarily caused by anoxia. Despite the rising rate and potentially profound physical and psychosocial effects of seizures and epilepsy, these disorders have received surprisingly little research focus and attention in Iran. Referring older patients to a specialist or a specialist epilepsy center allows speedy assessment, appropriate investigation and treatment, and less likely to miss the diagnosis.

Regulations and guidelines regarding driving privileges of patients with epilepsy vary greatly worldwide. The aim of our study was twofold: firstly, to evaluate disobedient drivers in Greece and to elucidate their awareness of the law, emotional responses, and seizure profile and, secondly, to identify determinants of disobedience regarding driving among patients with epilepsy. All consecutive patients with epilepsy who visited the epilepsy outpatient clinic of two tertiary epilepsy centers were invited to participate in the study. One hundred ninety patients met our inclusion criteria. Fifty-two percent of our study population was aware of the driving restrictions. More than one out of three patients were disobedient (35.8%). Being a male was associated with a 6.07-fold increase in the odds of being disobedient (95% CI: 2.73-13.47, p < 0.001); being employed was associated with a 4.62-fold increase in the odds of being disobedient (95% CI: 2.20-9.68, p < 0.001); and each extra antiepileptic drug (AED) was associated with a decrease in the odds of disobedience by a factor of 0.41 (95% CI: 0.26-0.63, p < 0.001). Male gender, employment, and number of AEDs are important determinants of disobedience regarding driving among patients with epilepsy. Copyright © 2014 Elsevier Inc. All rights reserved.

Periictal and interictal headache including migraine in Dutch patients with epilepsy: a cross-sectional study.

2015-03-01

As early as in 1898, it was noted that there was a need to find "a plausible explanation of the long recognized affinities of migraine and epilepsy". However, results of recent studies are clearly conflicting on this matter. In this cross-sectional study, we aimed to define the prevalence and characteristics of both seizure-related and interictal headaches in patients with epilepsy (5-75years) seeking help in the tertiary epilepsy clinic SEIN in Zwolle. Using a questionnaire, subjects were surveyed on the existence of headaches including characteristics, duration, severity, and accompanying symptoms. Furthermore, details on epilepsy were retrieved from medical records (e.g., syndrome, seizure frequency, and use of drugs). Diagnoses of migraine, tension-type headache, or unclassifiable headache were made based on criteria of the International Classification of Headache Disorders. Between March and December 2013, 29 children and 226 adults were evaluated, 73% of whom indicated having current headaches, which is significantly more often when compared with the general population (p<0.001). Forty-nine percent indicated having solely interictal headache, while 29% had solely seizure-related headaches and 22% had both. Migraine occurs significantly more often in people with epilepsy in comparison with the general population (p<0.001), and the occurrence of tension-type headaches conforms to results in the general population. These results show that current headaches are a significantly more frequent problem amongst people with epilepsy than in people without epilepsy. When comparing migraine prevalence, this is significantly higher in the population of patients with epilepsy. Copyright © 2014 Elsevier Inc. All rights reserved.

Stigma of epilepsy.

Bandstra, Nancy F; Camfield, Carol S; Camfield, Peter R

2008-09-01

Epilepsy directly affects 50 million people worldwide. Most can achieve excellent seizure control; however, people living with epilepsy continue to suffer from enacted or perceived stigma that is based on myths, misconceptions and misunderstandings that have persisted for thousands of years. This paper reviews the frequency and nature of stigma toward epilepsy. Significant negative attitudes prevail in the adolescent and adult public worldwide leading to loneliness and social avoidance both in school and in the workplace. People with epilepsy are often wrongly viewed as having mental health and antisocial issues and as being potentially violent toward others. Twenty-five percent of adults having epilepsy describe social stigma as a result of their epilepsy. They fear rejection and often feel shame or loneliness from this diagnosis. The psychosocial and social impact of epilepsy is significant. Yet few specific interventions have been demonstrated to alter this perception. The effect on public education is primarily short-term, while change over the long-term in attitudes and inaccurate beliefs have not presently been proven effective. School education programming demonstrates improved knowledge and attitude a month after a classroom intervention, but persisting change over a longer period of time has not been evaluated. In-depth adult psycho-educational programs for adults with epilepsy improves knowledge, coping skills and level of felt stigma. However these gains have not demonstrated persistence over time. Myths, misconceptions and misunderstandings about epilepsy continue and programs aimed at increasing knowledge and reducing negative public attitudes should be enhanced.

Objective: To assess the epilepsy services and identify the challenges in hospitals without epilepsy monitoring units (EMUs). In addition, comparisons between governmental and private sectors, as well as between regions, are to be performed. Methods: A cross-sectional study conducted using an online questionnaire distributed to the secondary and tertiary hospitals without EMUs throughout the Kingdom of Saudi Arabia (KSA). The study was conducted from September 2013 to September 2015 and regular updates from all respondents were constantly made. Items in the questionnaire included the region of the institution, the number of pediatric and adult neurologists and neurosurgeons along with their subspecialties, the number of beds in the Neurology Department, whether they provide educational services and have epilepsy clinics and if they refer patients to an EMU or intend to establish one in the future. Results: Forty-three institutions throughout the Kingdom responded, representing a response rate of 54%. The majority of hospitals (58.1%) had no adult epileptologists. A complete lack of pediatric epileptologists was observed in 72.1% of hospitals. Around 39.5% were utilizing beds from internal medicine. Hospitals with an epilepsy clinic represented 34.9% across all regions and sectors. Hospitals with no intention of establishing an EMU represented 53.5%. Hospitals that did not refer their epileptic patients to an EMU represented 30.2%. Conclusions: Epilepsy services in KSA hospitals without EMUs are underdeveloped. PMID:27744461

Depression among people with a diagnosis of epilepsy is under-recognized. General practitioner (GP) screening for depression using a new scale developed specifically for patients with epilepsy, the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), has not before been reported. The aims were to examine the process of GP screening for depression in patients with epilepsy employing the widely used Patient Health Questionnaire-2 (PHQ-2) and the NDDI-E; to determine the impact of screening on GP-recognized depression; and to ascertain depression predictors. Patients were screened via their GPs. A subset of participants underwent clinical interview to assess screener accuracy. Use of either instrument almost doubled the proportion of GP-recognized depression. Ninety-four percent of those interviewed found screening acceptable. More recent and frequent seizures predicted screening positive. The results suggest that screening for depression in patients with epilepsy via GPs improves detection of depression and is acceptable to interviewed patients. Copyright © 2011 Elsevier Inc.

It has been debated in the literature whether patients with idiopathic generalized epilepsy (IGE) have a distinctive, evening-oriented chronotype. The few questionnaire-based studies that are available in the literature have conflicting results. The aim of our study was to define chronotype in patients with IGE by determining dim light melatonin onset (DLMO). Twenty adults diagnosed with IGE (grand mal on awakening [GM] in 7 cases and juvenile myoclonic epilepsy in 13 cases) were investigated by means of a face-to-face semistructured sleep interview, Morningness-Eveningness Questionnaire (MEQ), Pittsburgh Sleep Quality Index (PSQI) questionnaire, and a melatonin salivary test with DLMO determination. Eighteen healthy subjects (HC) and 28 patients affected with cryptogenic focal epilepsy (FE) served as controls. The mean MEQ score was significantly lower in patients with IGE than that in patients with FE (49.1±5.9 versus 56.1±8.7 P<0.01) but not significantly lower than that in HC (49.1±5.9 versus 49.3±8.6). Midsleep on free days corrected for sleep duration did not differ significantly between the three subject groups (04:59±01:21h, 04:37±01:17h, 04:29±00:52h). The mean DLMO time in patients with IGE (22:13±01:34h) occurred 49min later than that in HC (21.24±1h), and the melatonin surge within the 30-minute time interval after DLMO in patients with IGE was significantly lower than that in HC (1.51±2.7 versus 3.8±3.6pg/mL P=0.045). Subjective measures of chronotype do not indicate a definite evening-oriented chronotype in patients with IGE. However, the data concerning endogenous melatonin secretion indicate that patients with IGE tend to have a late circadian phase. Further studies are warranted in order to better define the late pattern of endogenous melatonin secretion in patients with IGE and to ascertain the role of this pattern in influencing behavioral chronotype in these subjects.

Neuropsychiatry services provide specialist input into the assessment and management of behavioral symptoms associated with a range of neurological conditions, including epilepsy. Despite the centrality of epilepsy to neuropsychiatry and the recent expansion of neuropsychiatry service provision, little is known about the clinical characteristics of patients with epilepsy who are routinely seen by a specialist neuropsychiatry service. This retrospective study filled this gap by retrospectively evaluating a naturalistic series of 60 consecutive patients with epilepsy referred to and assessed within a neuropsychiatry setting. Fifty-two patients (86.7%) had active epilepsy and were under the ongoing care of the referring neurologist for seizure management. The majority of patients (N=42; 70.0%) had a diagnosis of localization-related epilepsy, with temporal lobe epilepsy as the most common epilepsy type (N=37; 61.7%). Following clinical assessment, 39 patients (65.0%) fulfilled formal diagnostic criteria for at least one psychiatric disorder; nonepileptic attack disorder (N=37; 61.7%), major depression (N=23; 38.3%), and generalized anxiety disorder (N=16; 26.7%) were the most commonly diagnosed comorbidities. The clinical characteristics of patients seen in specialist neuropsychiatry settings are in line with the results from previous studies in neurology clinics in terms of both epilepsy and psychiatric comorbidity. Our findings confirm the need for the development and implementation of structured care pathways for the neuropsychiatric aspects of epilepsy, with focus on comorbid nonepileptic attacks and affective and anxiety symptoms. This is of particular importance in consideration of the impact of behavioral symptoms on patients' health-related quality of life. Copyright © 2016 Elsevier Inc. All rights reserved.

Although a number of epidemiologic studies have been conducted on the prevalence and incidence of epilepsy around the world, only a few studies have investigated the clinical characteristics of patients with epilepsy in a population-based sample. The purpose of the present study was to describe the clinical characteristics of treated patients with epilepsy in Korea via a nationwide medical records survey. The study population was obtained through a nationwide database registered to the Health Insurance Review and Assessment service. Patients were recruited from clinics and hospitals in each cluster according to region and referral level by random selection from a preallocated sample of patients. All patients were being treated with antiepileptic drug medication with or without a diagnosis code for epilepsy or seizure between January 2009 and December 2009. Among the 6,436 selected patients, 2,150 met the diagnostic criteria for epilepsy and were included in our survey on the clinical characteristics of patients who were with treated epilepsy. The proportion of male patients with epilepsy in this study was higher (1,226; 57.0%) than that of female patients. In addition, 10.6% of patients were first diagnosed with epilepsy in 2009, and 53.6% of patients experienced at least one seizure over the course of 2009; 78.1% were classified as having localization-related epilepsy, whereas 7.3% were considered to have generalized epilepsy. Thirty-five percent of patients were thus classified as idiopathic or cryptogenic cases. The most common cause of symptomatic epilepsy was trauma (10.0%), followed by stroke (9.6%), central nervous system (CNS) infection (5.7%), and hippocampal sclerosis (4.9%). This is the first nationwide study of the clinical characteristics of treated epilepsy in Korea using a national database validated by medical records survey. The etiologies of epilepsy and epilepsy syndrome classifications were comparable to those previously reported in other

To determine the incidence rates of sudden unexpected death in epilepsy (SUDEP) in different epilepsy populations and address the question of whether risk factors for SUDEP have been identified. Systematic review of evidence; modified Grading Recommendations Assessment, Development, and Evaluation process for developing conclusions; recommendations developed by consensus. Findings for incidence rates based on 12 Class I studies include the following: SUDEP risk in children with epilepsy (aged 0-17 years) is 0.22/1,000 patient-years (95% confidence interval [CI] 0.16-0.31) (moderate confidence in evidence). SUDEP risk increases in adults to 1.2/1,000 patient-years (95% CI 0.64-2.32) (low confidence in evidence). The major risk factor for SUDEP is the occurrence of generalized tonic-clonic seizures (GTCS); the SUDEP risk increases in association with increasing frequency of GTCS occurrence (high confidence in evidence). Level B: Clinicians caring for young children with epilepsy should inform parents/guardians that in 1 year, SUDEP typically affects 1 in 4,500 children; therefore, 4,499 of 4,500 children will not be affected. Clinicians should inform adult patients with epilepsy that SUDEP typically affects 1 in 1,000 adults with epilepsy per year; therefore, annually 999 of 1,000 adults will not be affected. For persons with epilepsy who continue to experience GTCS, clinicians should continue to actively manage epilepsy therapies to reduce seizures and SUDEP risk while incorporating patient preferences and weighing the risks and benefits of any new approach. Clinicians should inform persons with epilepsy that seizure freedom, particularly freedom from GTCS, is strongly associated with decreased SUDEP risk. © 2017 American Academy of Neurology.

Epilepsy informatics and an ontology-driven infrastructure for large database research and patient care in epilepsy.

The epilepsy community increasingly recognizes the need for a modern classification system that can also be easily integrated with effective informatics tools. The 2010 reports by the United States President's Council of Advisors on Science and Technology (PCAST) identified informatics as a critical resource to improve quality of patient care, drive clinical research, and reduce the cost of health services. An effective informatics infrastructure for epilepsy, which is underpinned by a formal knowledge model or ontology, can leverage an ever increasing amount of multimodal data to improve (1) clinical decision support, (2) access to information for patients and their families, (3) easier data sharing, and (4) accelerate secondary use of clinical data. Modeling the recommendations of the International League Against Epilepsy (ILAE) classification system in the form of an epilepsy domain ontology is essential for consistent use of terminology in a variety of applications, including electronic health records systems and clinical applications. In this review, we discuss the data management issues in epilepsy and explore the benefits of an ontology-driven informatics infrastructure and its role in adoption of a "data-driven" paradigm in epilepsy research.

Relevant to the study of epileptogenesis is learning processing, given the pivotal role that neuroplasticity assumes in both mechanisms. Recently, evoked potential analyses showed a link between analytic cognitive style and altered neural excitability in both migraine and healthy subjects, regardless of cognitive impairment or psychological disorders. In this study we evaluated analytic/global and visual/auditory perceptual dimensions of cognitive style in patients with epilepsy. Twenty-five cryptogenic temporal lobe epilepsy (TLE) patients matched with 25 idiopathic generalized epilepsy (IGE) sufferers and 25 healthy volunteers were recruited and participated in three cognitive style tests: "Sternberg-Wagner Self-Assessment Inventory", the C. Cornoldi test series called AMOS, and the Mariani Learning style Questionnaire. Our results demonstrate a significant association between analytic cognitive style and both IGE and TLE and respectively a predominant auditory and visual analytic style (ANOVA: p values <0,0001). These findings should encourage further research to investigate information processing style and its neurophysiological correlates in epilepsy. Copyright © 2017 Elsevier Inc. All rights reserved.

2015-10-01

The purpose of this study was to assess the risk factors for early disability pension (EDP) in adult patients with epilepsy in a specialized epilepsy rehabilitation setting. In a retrospective study, 246 patients with epilepsy and employment difficulties leading to referral to an inpatient rehabilitation unit were evaluated with a questionnaire on admission and after a mean of 2.5years after discharge. Patients already receiving EDP at baseline were excluded. Epilepsy-related, demographic, and employment-related data as well as cognitive functioning and psychiatric comorbidity were assessed as risk factors for EDP at follow-up and analyzed using logistic regression models. Seventy-six percent of the patients had uncontrolled epilepsy, and 66.7% had psychiatric comorbidity. At follow-up, 33.7% received an EDP. According to multivariate logistic regression analysis, age>50years (odds ratio (OR) 5.44, compared to age<30years), application for an EDP prior to admission (OR 3.7), sickness absence>3months in the previous year (OR 3.30, compared to sickness absence<3months), and psychiatric comorbidity (OR 2.79) were significant risk factors for an EDP at follow-up, while epilepsy-related factors and cognitive impairment showed an effect only in the univariate analyses. Potential risk factors for EDP in patients with epilepsy were evaluated using multivariate analysis. Knowledge of such factors may help to develop appropriate criteria for rehabilitation candidacy and interventions to reduce the risk for EDP. This might lead to an amelioration of both psychosocial burden of patients and economic burden on society. Copyright © 2015 Elsevier Inc. All rights reserved.

Disclosure management behaviors in Korean adults with well-controlled epilepsy: Their relation to perception of stigma.

In spite of the fact that epilepsy is a concealable stigmatized identity, there is little evidence pertaining to disclosure management in adults living with epilepsy. We determined the factors contributing to disclosure management strategies in adults living with well-controlled epilepsy. This was a cross-sectional multicenter study. Korean adults whose seizures had remitted for at least one year participated in this study. Using statistical analyses, we determined whether disclosure management behaviors measured using the Disclosure Management Scale (DMS) were related to demographic, clinical, and psychosocial variables. The Stigma Scale and Hospital Anxiety Depression Scale (HADS) were used. Of a total of 225 participants, 76% stated that they often or sometimes kept their epilepsy a secret, while 24% reported that they never or rarely kept their diagnosis hidden. The mean DMS score was 6.1 (SD=2.4). In univariate analyses, the DMS scores were significantly related to the HADS depression scores (r=0.187, p=0.005) and the presence of perceived stigma (p=0.001). In linear regression analyses, perceived stigma was identified only as an independent factor associated with DMS scores (p=0.031), while HADS depression lost significance (p=0.057). The presence of perceived stigma explained only 4.6% of the variance in DMS scores. Our study shows that over 70% of Korean adults with well-controlled epilepsy often or sometimes keep their epilepsy a secret. Although perceived stigma is associated with concealment behaviors, it accounts for only a small proportion of the variance in disclosure management. Copyright © 2016 Elsevier Inc.

Although differences in illness perceptions between neurologists and patients with epilepsy or psychogenic nonepileptic seizures (PNES) are likely to be clinically relevant, this is the first study to attempt a direct comparison. In addition, this study compares the illness perceptions of patients with epilepsy with those of patients with PNES. Thirty-four patients with epilepsy, 40 patients with PNES, and 45 neurologists were recruited. All patient participants completed versions of the illness perception questionnaire revised (IPQ-R) adapted for epileptic or nonepileptic seizure disorders, single-item symptom attribution question (SAQ), Hospital Anxiety and Depression Scale (HADS), Quality of Life in Epilepsy-31 (QOLIE-31), and Liverpool Seizure Severity Scale (LSSS). Participating neurologists completed two versions of the IPQ-R and two SAQs for epileptic and nonepileptic seizure disorders. Differences in illness perceptions between patients with epilepsy and patients with PNES were minor compared to those between patients with either seizure disorder and neurologists. Neurologists considered both seizure disorders more treatable and more amenable to personal control than did the patients themselves. Neurologists had much more polarized views of the etiology of both conditions; whereas patients mostly considered the causes of their seizure disorders as partially "physical" and partially "psychological," neurologists perceived epilepsy as an essentially "physical" and PNES as a clearly "psychological" problem. There are considerable differences between the illness perceptions of patients with seizure disorders and their doctors, which could represent barriers to successful clinical management. In particular, a discrepancy between neurologists' and patients' beliefs about the personal control that patients may be able to exert over PNES could contribute to the confusion or anger some patients report after the diagnosis has been explained to them.

Sleep and Epilepsy: Strange Bedfellows No More.

Ancient philosophers and theologians believed that altered consciousness freed the mind to prophesy the future, equating sleep with seizures. Only recently has the bidirectional influences of epilepsy and sleep upon one another received more substantive analysis. This article reviews the complex and increasingly recognized interrelationships between sleep and epilepsy. NREM sleep differentially activates interictal epileptiform discharges during slow wave (N3) sleep, while ictal seizure events occur more frequently during light NREM stages N1 and N2. The most commonly encountered types of sleep-related epilepsies (those with preferential occurrence during sleep or following arousal) include frontal and temporal lobe partial epilepsies in adults, and benign epilepsy of childhood with centrotemporal spikes (benign rolandic epilepsy) and juvenile myoclonic epilepsy in children and adolescents. Comorbid sleep disorders are frequent in patients with epilepsy, particularly obstructive sleep apnea in refractory epilepsy patients which may aggravate seizure burden, while treatment with nasal continuous positive airway pressure often improves seizure frequency. Distinguishing nocturnal events such as NREM parasomnias (confusional arousals, sleep walking, and night terrors), REM parasomnias including REM sleep behavior disorder, and nocturnal seizures if frequently difficult and benefits from careful history taking and video-EEG-polysomnography in selected cases. Differentiating nocturnal seizures from primary sleep disorders is essential for determining appropriate therapy, and recognizing co-existent sleep disorders in patients with epilepsy may improve their seizure burden and quality of life.

Levetiracetam efficacy on frontal lobe dysfunctions and anger rumination in patients with epilepsy.

This study compared the frontal lobe functioning and anger rumination between patients with epilepsy and healthy individuals. The second objective was to examine the efficacy of levetiracetam therapy on frontal lobe dysfunctions and anger rumination in patients with epilepsy. Participants (50 patients with epilepsy and 50 healthy individuals) completed the Frontal Assessment Battery (FAB) and Anger Rumination Scale (ARS). The patients had two testing sessions: pre- and post-levetiracetam therapies. The results showed that patients with epilepsy had frontal lobe dysfunctions in contrast with healthy individuals. Patients with epilepsy had higher anger rumination than healthy individuals. Compared with baseline performance, frontal lobe dysfunctions and anger rumination were significantly reduced after three months of levetiracetam therapy in patients with epilepsy. It is concluded that levetiracetam therapy may be beneficial in improving frontal lobe functioning and anger rumination thought pattern in patients with epilepsy. However, further studies are required to confirm this evidence. Copyright © 2018 Elsevier Inc. All rights reserved.

[Building epilepsy care network in Japan].

Number of epilepsy patient in Japan officially surveyed by our government in 2008 is 219,000, which is only 0.17% of the total population and less than one third of the prevalence rate reported in Western countries. Number of epilepsy surgery per year in Japan is also low and less than half of other countries such as US, UK and Korea. These numbers may suggest that epilepsy care in Japan is not sufficient to cover all hidden medical needs of people with epilepsy at present. To solve this issue, our research group funded by the government have started to build an epilepsy care network among primary care physicians, secondary care neurology specialists and tertiary care epilepsy centers by utilizing a web site: Epilepsy Care Network-Japan (http://www.ecn-japan.com/) from July 2012. We are also proposing an epilepsy care algorithm suitable for our complex medical community consisted with various neurology specialists such as pediatric and adult neurologists, neurosurgeons and psychiatrists. Building Epilepsy Care Network in Japan may facilitate better medical and social support for people with epilepsy in Japan.

Qué es la Epilepsia? Attitudes and knowledge of epilepsy by Spanish-speaking adults in the United States.

Spanish-speaking adults are the largest minority population group in the United States and are disproportionately afflicted by epilepsy. A unique 78-item survey instrument conducted entirely in Spanish and devoted to the topic of epilepsy was administered to 760 Spanish-speaking adults in seven large U.S. Hispanic metropolitan areas representing a cross section of the U.S. Hispanic community. The answers were compared with those of 272 non-Hispanic controls administered the same survey in English in June 2004. The Hispanic sample correlated well with U.S. Census data. Spanish-speaking adults are mostly unaware about epilepsy, with 21% reporting no familiarity with the condition (P=0.0001). The vast majority of Hispanics use the term convulsiones or ataque to describe a seizure. Thirteen percent of Hispanics with less than high school education believe that epilepsy is contagious (P=0.0001); 8% see "sins" as a cause of seizures (P=0.0001); and 10% agree that "exorcism" would be a good remedy (P=0.002). There is considerable misinformation about epilepsy in the U.S. Hispanic community. Neurologists must be made aware of U.S. Hispanic attitudes and beliefs regarding epilepsy to provide culturally competent care.

The aim of this study was to evaluate physician adherence to the German Neurological Society guidelines of 2008 regarding initial monotherapy and to determine the cost-of-illness in epilepsy. This was an observational cohort study using health data routinely collected at 55 outpatient neurology practices throughout Germany (NeuroTransData network). Data on socioeconomic status, course of epilepsy, anticonvulsive treatment, and direct and indirect costs were recorded using practice software-based questionnaires. One thousand five hundred eighty-four patients with epilepsy (785 male (49.6%); mean age: 51.3±18.1years) were enrolled, of whom 507 were newly diagnosed. Initial monotherapy was started according to authorization status in 85.9%, with nonenzyme-inducing drugs in 94.3% of all AEDs. Drugs of first choice by guideline recommendations were used in 66.5%. Total annual direct costs in the first year amounted to €2194 (SD: €4273; range: €55-43,896) per patient, with hospitalization (59% of total direct costs) and anticonvulsants (30%) as the main cost factors. Annual total direct costs decreased by 29% to €1572 in the second year, mainly because of a 59% decrease in hospitalization costs. The use of first choice AEDs did not influence costs. Chronic epilepsy was present in 1077 patients, and total annual direct costs amounted to €1847 per patient, with anticonvulsants (51.0%) and hospitalization (41.0%) as the main cost factors. Potential cost-driving factors in these patients were active epilepsy and focal epilepsy syndrome. This study shows excellent physician adherence to guidelines regarding initial monotherapy in adults with epilepsy. Newly diagnosed patients show higher total direct and hospital costs in the first year upon diagnosis, but these are not influenced by adherence to treatment guidelines.

To determine outcome after epilepsy surgery in patients with normal preoperative magnetic resonance imaging (MRI). 24 adult and paediatric patients with normal preoperative MRIs were studied. They underwent epilepsy surgery between 1994 and 2001 and had at least one year of follow up. At the most recent follow up, nine patients (37%) were seizure-free and 18 (75%) had at least a 90% reduction in seizure frequency with weekly or monthly seizures. Seizure freedom was not significantly different after resections in frontal (5/9) or temporal regions (4/13) (p = 0.24, Fisher's exact test), or among patients with or without localising features on EEG, PET, or ictal SPECT. Subdural grids, used in 15 of 24 patients, helped tailor resections but were not associated with differences in outcome. Histopathology showed cortical dysplasia in 10 patients (42%), non-specific findings in 13 (54%), and hippocampal sclerosis in one (4%). Cortical dysplasia was seen in seven patients with frontal resection (78%) and non-specific findings in nine (69%) with temporal resection. Seizure outcome did not differ on the basis of location of resection or histopathology. While these results were less favourable than expected for patients with focal epileptogenic lesions seen on MRI, they represented worthwhile improvement for this patient population with high preoperative seizure burden. In this highly selected group, no single test or combination of tests further predicted postoperative seizure outcome.

Health-related quality of life in senior adults with epilepsy: what we know from randomized clinical trials and suggestions for future research.

The goal of this work was to review the randomized controlled trial (RCT) literature on antiepileptic medication effects on health-related quality of life in seniors with epilepsy. Studies published from 1998 to June 2002 were identified by searching through Medline and the Cochrane Clinical Trials Register. Pre-1998 RCTs identified by Baker et al. [Epilepsia 41 (2003) 1357] were also examined for relevance to the present review. Studies were reviewed if they included a RCT design and included epilepsy patients over the age of 60. A total of 85 clinical trials were reviewed. Of the 85 studies reviewed only 37 RCT studies included patients over the age of 60. However, formal quality-of-life outcome assessment was not performed in any of the RCTs that included senior adults, and only six studies provided formal quantitative analyses of AED effects in the form of adverse events incidence and participant withdrawal rates. For the most part, early study withdrawal rates were substantial for seniors and adverse events were very common. Two studies reporting on the cognitive and behavioral effects of study AEDs indicated only modest impact when AED monotherapy was kept at therapeutic levels. Despite growing appreciation for quality-of-life, issues in the management of epilepsy little current empirical guidance is available for elderly with epilepsy. There exists virtually no information on elderly patient preferences and goals for epilepsy treatment outcomes, and available data primarily concerns younger adults. Despite some encouraging preliminary evidence from this review suggesting that conservative AED treatment may have a more favorable quality of life-related outcome, more conclusive statements await further systematic investigation.

Long-term lacosamide retention-Real-world experience at a tertiary epilepsy center in Ireland.

McGinty, Ronan N; Costello, Daniel J

2017-03-01

To estimate the rate of long-term lacosamide retention among a real-world group of patients at a tertiary epilepsy center in Ireland. One-hundred adults first prescribed lacosamide for epilepsy between January 2010 and August 2014 at Cork University Hospital were randomly selected for a retrospective analysis of medical records covering two years of subsequent epilepsy clinic follow-up to ascertain whether lacosamide was continued or withdrawn. Of 100 patients, (51 males, mean age 40.8years, 94 with drug-resistant epilepsy, 76 with focal epilepsy, 25 with intellectual disabilities, 34 with mental health disorders, and 42 with medical comorbidities), lacosamide was prescribed as an adjunct in 85. Lacosamide retention at 12 and 24months was 76% and 71%, respectively. Twenty-five patients stopped lacosamide due to ineffective seizure control. Adverse-effects were responsible for lacosamide discontinuation in three patients and one patient stopped lacosamide pre-pregnancy. The relatively high retention rate at two years suggests that lacosamide is generally well tolerated among people with a range of different epilepsy subtypes, intellectual disabilities, medical comorbidities, and mental health disorders, and can aid seizure control in adult patients with a range of difficult-to-treat epilepsies.

An effective informatics infrastructure for epilepsy, which is underpinned by a formal knowledge model or ontology, can leverage an ever increasing amount of multimodal data to improve (1) clinical decision support, (2) access to information for patients and their families, (3) easier data sharing, and (4) accelerate secondary use of clinical data. Modeling the recommendations of the International League Against Epilepsy (ILAE) classification system in the form of an epilepsy domain ontology is essential for consistent use of terminology in a variety of applications, including electronic health records systems and clinical applications. In this review, we discuss the data management issues in epilepsy and explore the benefits of an ontology-driven informatics infrastructure and its role in adoption of a “data-driven” paradigm in epilepsy research.

The present study aims to accurately localize epileptogenic regions which are responsible for epileptic activities in epilepsy patients by means of a new subspace source localization approach, i.e. first principle vectors (FINE), using scalp EEG recordings. Computer simulations were first performed to assess source localization accuracy of FINE in the clinical electrode set-up. The source localization results from FINE were compared with the results from a classic subspace source localization approach, i.e. MUSIC, and their differences were tested statistically using the paired t-test. Other factors influencing the source localization accuracy were assessed statistically by ANOVA. The interictal epileptiform spike data from three adult epilepsy patients with medically intractable partial epilepsy and well-defined symptomatic MRI lesions were then studied using both FINE and MUSIC. The comparison between the electrical sources estimated by the subspace source localization approaches and MRI lesions was made through the coregistration between the EEG recordings and MRI scans. The accuracy of estimations made by FINE and MUSIC was also evaluated and compared by R2 statistic, which was used to indicate the goodness-of-fit of the estimated sources to the scalp EEG recordings. The three-concentric-spheres head volume conductor model was built for each patient with three spheres of different radii which takes the individual head size and skull thickness into consideration. The results from computer simulations indicate that the improvement of source spatial resolvability and localization accuracy of FINE as compared with MUSIC is significant when simulated sources are closely spaced, deep, or signal-to-noise ratio is low in a clinical electrode set-up. The interictal electrical generators estimated by FINE and MUSIC are in concordance with the patients' structural abnormality, i.e. MRI lesions, in all three patients. The higher R2 values achieved by FINE than MUSIC

Advances in neuroimaging, genomics, and molecular biology have improved the understanding of the pathogenesis of epilepsy. That is why the International League Against Epilepsy (ILAE) has created a new classification system. The present study aims to evaluate the association between epilepsy cases classified by the ILAE 2010 classification proposal, electroencephalography (EEG), and magnetic resonance imaging brain findings (MRI). Prospective cross-sectional design of 277 cases of epilepsy seen at the Epilepsy Clinic, Hospital Central "Dr. Ignacio Morones Prieto", were compared with the ILAE classification based on the etiology and clinical manifestations and their MRI and EEG findings. Cochran, Mantell, Haenzel test with significance p<0.05. MRI findings were associated with the etiology of the ILAE classification. According to EEG findings, the structural-metabolic etiology patients had more dysfunctional reports than genetic or unknown etiology patients (p<0.05). The adoption of the ILAE classification is recommended, as it can provide useful guidance towards the etiology of cases of epilepsy even when brain MRIs and EEGs are not available.

Psychotic illness in patients with epilepsy

PubMed Central

Tadokoro, Yukari; Oshima, Tomohiro

2012-01-01

Apart from the rather rare ictal psychotic events, such as non-convulsive status epilepticus, modern epileptic psychoses have been categorized into three main types; chronic and acute interictal psychoses (IIPs) and postictal psychosis (PIP). Together, they comprise 95% of psychoses in patients with epilepsy (PWE). Four major questions, that is, “Is psychosis in PWE a direct consequence of epilepsy or schizophrenia induced by epilepsy?”, “Is psychosis in PWE homogeneous or heterogeneous?”, “Does psychosis in PWE have symptomatological differences from schizophrenia and related disorders?”, “Is psychosis in PWE uniquely associated with temporal lobe epilepsy (TLE)?” are tried to be answered in this review with relevant case presentations. In the final section, we propose a tentative classification of psychotic illness in PWE, with special attention to those who have undergone epilepsy surgery. Psychotic disorders in PWE are often overlooked, mistreated, and consequently lingering on needlessly. While early diagnosis is unanimously supported as a first step to avoid this delay, necessity of switching from antiepileptic drugs with supposedly adverse psychotopic effects. to others is more controversial. To elucidate the riddle of alternative psychosis, we need badly further reliable data. PMID:23139703

Objective: To evaluate the potential efficacy of immediate-release methylphenidate (MPH) for treating cognitive deficits in epilepsy. Methods: This was a double-blind, randomized, single-dose, 3-period crossover study in patients with epilepsy and chronic cognitive complaints comparing the effects of placebo and MPH 10 and 20 mg given 1 week apart. Cognitive outcome was evaluated on the basis of an omnibus z score calculated from performance on the Conners Continuous Performance Test 3 (ability to discriminate between target and nontarget stimuli [d'] and hit reaction time standard deviation), Symbol-Digit Modalities Test, and Medical College of Georgia Paragraph Memory Test. Adverse events and seizure frequency were monitored. An open-label follow-up is reported elsewhere. Results: Thirty-five adult patients with epilepsy participated, of whom 31 finished. Demographics included the following: mean age = 35.3 years (range 20–62 years), 13 men and 18 women, and baseline seizure frequency of 2.8 per month. Epilepsy types were focal (n = 24), generalized (n = 6), or unclassified (n = 1). Mean epilepsy duration was 12.5 years. A statistically significant performance benefit was present at both 10-mg (p = 0.030) and 20-mg (p = 0.034) MPH doses. No seizures were associated with either MPH dose. Adverse effects leading to withdrawal included cognitive “fogginess” (n = 1 on 20 mg), anxiety/agitation (n = 1 on 10 mg), and tachycardia (n = 1). One participant was lost to follow-up after one 20-mg dose without side effect. Conclusions: This single-dose study suggests that MPH may be effective in ameliorating some cognitive deficits in patients with epilepsy. Additional studies are required. ClinicalTrials.gov identifier: NCT02178995. Classification of evidence: This study provides Class II evidence that single doses of MPH improve cognitive performance on some measures of attention and processing speed in patients with epilepsy and cognitive complaints.

Epilepsy in transition from child care to adult service: a missing link in sub-Saharan Africa.

Epilepsy is a common chronic neurological disease which predominantly affects children and young adults. The disease is highly stigmatised and transition from child care to adult services is not routine in many low- and middle-income countries. Where a treatment system follows routines which cannot be sustained in such countries because of specialised manpower challenges, it becomes imperative that appropriate care models be sought for patients whose seizures fail to remit in childhood. In teaching hospitals, well-organised, multidisciplinary meetings and a planned transfer between paediatric and adult neurologists will be feasible. However, an alternative model is advocated at the community level where the majority of the patients reside which involves task shifting to general practitioners and community healthcare workers. The latter can organise home visits to ensure management compliance. This will ensure better seizure outcomes and a good quality of life for epileptic patients.

Mutations in the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene are responsible for a severe encephalopathy with early epilepsy. So far, the electroclinical phenotype remains largely unknown and no clear genotype-phenotype correlations have been established. To characterize the epilepsy associated with CDKL5 mutations and to look for a relationship between the genotype and the course of epilepsy. We retrospectively analyzed the electroclinical phenotypes of 12 patients aged from 2.5 to 19 years diagnosed with pathogenic CDKL5 mutations and one patient with a novel intronic sequence variation of uncertain pathogenicity and examined whether the severity of the epilepsy was linked to the type and location of mutations. The epilepsy course reveals three successive stages: (Stage I) early epilepsy (onset 1-10 weeks) with normal interictal electroencephalogram (EEG) (10/13) despite frequent convulsive seizures; (Stage II) epileptic encephalopathy with infantile spasms (8/8) and hypsarrhythmia (8/8). At the age of evaluation, seven patients were seizure free and six had developed refractory epilepsy (stage III) with tonic seizures and myoclonia (5/6). Interestingly, the patients carrying a CDKL5 mutations causing a truncation of the catalytic domain tended to develop a more frequent refractory epilepsy than patients with mutations located downstream (4/6, 66.6% versus 1/6, 16%) although, these trends are not yet significant. Our data contribute to a better definition of the epileptic phenotype in CDKL5 mutations, and might give some clues to a potential relationship between the phenotype and the genotype in these patients.

Depression is a frequent comorbidity in patients with epilepsy (PWE). However, it is often undertreated because of concerns of seizure exacerbation by antidepressant treatment. The effect of tianeptine on seizure frequency is not known as yet. Thus, we aimed to evaluate the influence of tianeptine on the seizure frequency in PWE. We retrospectively reviewed the medical records of PWE who received tianeptine between January 2006 and June 2013 at the Epilepsy Center of Seoul National University Hospital. Patients were excluded if the dose or type of antiepileptic drugs (AEDs) they took was altered at the start of tianeptine treatment or if the treatment period of tianeptine was <3 months. A total of 74 PWE were enrolled in our study (male: 32, mean age: 41.9±14.5). Sixty-nine patients had localization-related epilepsy, and 5 had idiopathic generalized epilepsy (IGE). Mean seizure frequency during the 3-month period just after tianeptine exposure was compared with the baseline seizure frequency, which showed no change in 69 (93.2%) patients, decrease in 2 (2.7%) patients, and increase in 3 patients (4.1%). The type of epileptic syndrome, the baseline seizure frequency, and the number of coadministered AEDs did not influence the change in seizure frequency after tianeptine prescription. Change in seizure frequency did not differ between the patients given tianeptine as an additive antidepressant and those given tianeptine as a replacement antidepressant. Our data suggest that tianeptine can be prescribed safely to PWE with depression without increasing the seizure frequency regardless of the baseline severity of epilepsy. Tianeptine may be actively considered as a first-choice antidepressant or as an alternative antidepressant in PWE with depression. Copyright © 2014 Elsevier Inc. All rights reserved.

Satisfaction with life domains in people with epilepsy.

2012-12-01

While commonly used quality-of-life instruments assess perceived epilepsy-associated limitations in life domains and formally document patient concerns, less is known of community-dwelling adults with epilepsy about their satisfaction with broader life domains, such as satisfaction with housing, education, neighborhood, ability to help others, and achievement of goals. The purpose of this study was to examine satisfaction with life domains in a representative sample of community-dwelling adults with self-reported epilepsy from the 2008 HealthStyles survey. Following adjustment for sex, age group, race/ethnicity, education, and income, people with epilepsy were more likely to report frustration in the domains of achievement (e.g., dissatisfaction with education and life goals), compromised social interactions (dissatisfaction with family life, friends, and social life), and compromised physical capability (dissatisfaction with health and energy level). Life satisfaction and other well-being domains can supplement health indicators to guide treatment and program services for people with epilepsy to maximize their well-being.

Given the significant impact that psychosocial factors and epilepsy treatments can have on the health-related quality of life (HRQOL) of individuals with epilepsy and their families, there is great clinical interest in the role of psychological evaluation and treatments to improve HRQOL and comorbidities. Therefore, the International League Against Epilepsy (ILAE) charged the Psychology Task Force with the development of recommendations for clinical care based on evaluation of the evidence from their recent Cochrane review of psychological treatments in individuals with epilepsy. The literature search for a recent Cochrane review of randomized controlled trials investigating psychological treatments for individuals with epilepsy constitutes the key source of evidence for this article. To provide practical guidance to service providers, we provide ratings on study research designs based on (1) the American Academy of Neurology's Level of Evidence system and (2) the Grading of Recommendations, Assessment, Development, and Evaluation system. This paper is the culmination of an international collaboration process involving pediatric and adult psychologists, neurologists, psychiatrists, and neuropsychiatrists. The process and conclusions were reviewed and approved by the ILAE Executive Committee. The strongest evidence for psychological interventions was identified for the most common mental health problems, including depression, neurocognitive disturbances, and medication adherence. Psychological interventions targeting the enhancement of HRQOL and adherence and a decrease in comorbidity symptoms (anxiety, depression) should be incorporated into comprehensive epilepsy care. There is a range of psychological strategies (ie, cognitive behavioral therapy and mindfulness-based therapies) that show promise for improving the lives of persons with epilepsy, and clinical recommendations are provided to assist epilepsy health care providers in treating the comorbidities and

A clinical diagnosis of epilepsy often carries a silent social stigma and is associated with metaphysical forces. This qualitative study aimed to explore the Iranian patients' perception of epilepsy where clinical aspects are more benign than the social implications with long-term psychological consequences. Historically, epilepsy has been known as a form of insanity, madness, sorcery, and possession by evil spirits. Thirty participants consisting of 21 patients with epilepsy, 5 family members, and 4 medical staff were selected from urban and rural medical and health care centers, hospitals, physician offices, outpatient clinics, and the Iranian Epilepsy Association. Unstructured and semistructured interviews were applied to obtain data. Transcribed interviews and field notes were analyzed using qualitative content analysis method. Categories and subcategories emerged from the participants' perceptions of epilepsy and its disruptive effects on their self-identity. The main categories derived from data were 1) a different perspective about epilepsy, 2) self-debasement, and 3) being a burden. The major theme found in this study was "identity loss". Our study results highlight the importance of public awareness among community members and healthcare professionals on how patients with epilepsy experience their disease with psychosocial implications. Understanding patients' perspectives can be essential to developing a comprehensive and holistic care plan for patients with epilepsy and addressing their multidimensional needs.

In adults with intellectual disability (ID) and epilepsy there are suggestions that improvements in management may follow introduction of epilepsy nurse-led care. However, this has not been tested in a definitive clinical trial and results cannot be generalised from general population studies as epilepsy tends to be more severe and to involve additional clinical comorbidities in adults with ID. This trial investigates whether nurses with expertise in epilepsy and ID, working proactively to a clinically defined role, can improve clinical and quality of life outcomes in the management of epilepsy within this population, compared to treatment as usual. The trial also aims to establish whether any perceived benefits represent good value for money. The EpAID clinical trial is a two-arm cluster randomised controlled trial of nurse-led epilepsy management versus treatment as usual. This trial aims to obtain follow-up data from 320 participants with ID and drug-resistant epilepsy. Participants are randomly assigned either to a 'treatment as usual' control or a 'defined epilepsy nurse role' active arm, according to the cluster site at which they are treated. The active intervention utilises the recently developed Learning Disability Epilepsy Specialist Nurse Competency Framework for adults with ID. Participants undergo 4 weeks of baseline data collection, followed by a minimum of 20 weeks intervention (novel treatment or treatment as usual), followed by 4 weeks of follow-up data collection. The primary outcome is seizure severity, including associated injuries and the level of distress manifest by the patient in the preceding 4 weeks. Secondary outcomes include cost-utility analysis, carer strain, seizure frequency and side effects. Descriptive measures include demographic and clinical descriptors of participants and clinical services in which they receive their epilepsy management.

We investigated causes of death in children and young adults with epilepsy by using data from the U.S. National Child Death Review Case Reporting System (NCDR-CRS), a passive surveillance system composed of comprehensive information related to deaths reviewed by local child death review teams. Information on a total of 48,697 deaths in children and young adults 28days to 24years of age, including 551 deaths with epilepsy and 48,146 deaths without epilepsy, was collected from 2004 through 2012 in 32 states. In a proportionate mortality analysis by official manner of death, decedents with epilepsy had a significantly higher percentage of natural deaths but significantly lower percentages of deaths due to accidents, homicide, and undetermined causes compared with persons without epilepsy. With respect to underlying causes of death, decedents with epilepsy had significantly higher percentages of deaths due to drowning and most medical conditions including pneumonia and congenital anomalies but lower percentages of deaths due to asphyxia, weapon use, and unknown causes compared with decedents without epilepsy. The increased percentages of deaths due to pneumonia and drowning in children and young adults with epilepsy suggest preventive interventions including immunization and better instruction and monitoring before or during swimming. State-specific and national population-based mortality studies of children and young adults with epilepsy are recommended. Published by Elsevier Inc.

Background: The impact of seizure disorder on people living with epilepsy (PWE) is worsened by the occurrence of comorbid psychiatric disorders, such as depression, which have been found commonly in PWE. Despite the dire consequences comorbid depression has on PWE, it still remains underdiagnosed and undertreated. Objective: To determine the prevalence of depression and associated clinical factors in PWE in Northwestern Nigeria. Materials and Methods: A total of 255 consecutive patients with epilepsy aged 18 years and above, from two health facilities, were recruited in this cross-sectional study. Following completion of a structured proforma detailing sociodemographic and seizure characteristics, Mini International Neuropsychiatric Interview was administered to diagnose depression in the patients. Results: A total of 255 patients, with a mean age of 32 years (standard deviation = 1.31), comprising 147 (57.6%) males and 108 (42.4%) females were studied. Majority (79.2%) of the patients had primarily generalized seizure type. Overall, depressive disorder was present in 52 (20.4%) patients. A significant association was found between previous hospitalization for epilepsy (P = 0.009), increased frequency of seizures, (P = 0.004), and prolonged duration of epilepsy, (P = 0.006). The independent predictors of depression included duration of epilepsy (P = 0.0001), previous hospitalization for epilepsy (P = 0.011), and frequency of seizures (P = 0.028). Conclusion: Depression was common in PWE. Female gender, previous hospitalization for epilepsy, increased frequency of seizures and prolonged duration of epilepsy were associated with depression in PWE. Previous hospitalization for epilepsy, increased frequency of seizures, and prolonged duration of epilepsy were independent predictors of depression. PMID:27853032

Oral loading of oxcarbazepine tablet is effective and well tolerated to adequately achieve the therapeutic levels of its active metabolite, 10,11-dihydro-10-hydroxy-carbazepine (monohydroxy derivative, MHD) in epilepsy patients. The present study was performed to investigate the safety, tolerability, and pharmacokinetic profiles of oral loading of oxcarbazepine suspension in epilepsy patients with a high risk of recurrent seizures. Oxcarbazepine suspension was administered orally at a single loading dose of 30 mg/kg to 38 adult patients with recurrent seizures, who required rapid seizure control or temporarily discontinued antiepileptic drugs for diagnostic or pre-surgical evaluation. Plasma concentrations of oxcarbazepine and MHD were determined, and adverse events were assessed at 2, 4, 6, 8, 10, 12, 14, 16, and 24 hours after oral loading of oxcarbazepine suspension. 30 patients experienced ≥ 1 adverse event during the first 24 hours after oral loading of oxcarbazepine (e.g., dizziness, transient diplopia, nausea or vomiting), most of which occurred within 4 hours after loading, suggesting no temporal association with MHD plasma levels. 35 (92.1%) patients were still compliant with a maintenance dose of oxcarbazepine after discharge from hospital. 34 (89.4%) patients reached the lower therapeutic level of MHD (12 mg/l) at 4 hours after oral loading of oxcarbazepine suspension, which lasted up to 24 hours in most patients. No patient reached the supratherapeutic levels of MHD (> 35 mg/l) during the study. The mean plasma concentration-time curves and pharmacokinetic profiles of oral loading of oxcarbazepine suspension were similar to those of oral loading of oxcarbazepine tablet. Oral loading of oxcarbazepine suspension followed by maintenance dosing is well tolerated and effective in steadily achieving the therapeutic level of MHD in selected patients with epilepsy.

Self-proxy agreement and correlates of health-related quality of life in young adults with epilepsy and mild intellectual disabilities.

This study investigated health-related quality of life (HRQOL) in young adults with epilepsy and intellectual disabilities. First, agreement between self-reports and proxy reports of HRQOL was examined. Second, medical and psychological contributions to HRQOL were explored. Thirty-six patients were interviewed using the Quality of Life in Epilepsy inventory (QOLIE-31), the Hospital Anxiety and Depression Scale, and the Neuroticism and Extraversion scales of the NEO Five-Factor Inventory. Medical data were taken from files. Professional caregivers completed rephrased QOLIE-31-questionnaires. The perspectives on HRQOL differed systematically: Caregivers underrated their clients' HRQOL on average. Few correlations with medical characteristics emerged, whereas all psychological variables were strongly related to HRQOL. Neuroticism, Age at Disability Onset, and their interaction explained 71% of the HRQOL variance. Results indicate that proxy reports do not provide valid substitutes for most of the self-reported HRQOL subscales. Psychological treatment of negative affectivity and after critical life events in adolescence may improve HRQOL in young adults with epilepsy and mild intellectual disabilities.

To estimate the prevalence of nocturnal frontal lobe epilepsy (NFLE) in the adults of two areas of the Emilia-Romagna region (northeast Italy) and to describe the clinical features from a population-based perspective. Population-based retrospective cohort study including adults with NFLE. Two areas of the Emilia-Romagna region: the city of Bologna (330,901 adult residents) and five districts of the province of Modena (424,007). Prevalence day: December 31, 2010. Patients with NFLE collected from multiple databases of neurologic hub centers of the districts involved. Diagnostic criteria: clinical history of sleep related bizarre motor attacks and videopolysomnographic recording confirming the typical features of NFLE. Inclusion criteria for prevalence calculation: residence in one of the two geographic areas on the prevalence day and an "active" or "in remission with treatment" form of NFLE. Six subjects from Bologna and eight from Modena were included. Crude prevalence (per 100,000 residents) was 1.8 (95% confidence interval 0.7-4.0) in Bologna and 1.9 (0.8-3.7) in Modena. Similarly, the main clinical features were consistent: onset during adolescence (median age 11-13 y), mainly hyperkinetic seizures, nonlesional form in more than two-thirds of cases, an active form of epilepsy in more than two-thirds of cases. A family history of epilepsy was reported only for two patients. This epidemiologic study establishes that NFLE is a rare epileptic condition, fulfilling the definition for rare disease. Because of methodological limitations of our case ascertainment, the estimates we disclose must be considered the minimum prevalence. © 2015 Associated Professional Sleep Societies, LLC.

Effects of Epilepsy on Language Functions: Scoping Review and Data Mining Findings.

Dutta, Manaswita; Murray, Laura; Miller, Wendy; Groves, Doyle

2018-03-01

This study involved a scoping review to identify possible gaps in the empirical description of language functioning in epilepsy in adults. With access to social network data, data mining was used to determine if individuals with epilepsy are expressing language-related concerns. For the scoping review, scientific databases were explored to identify pertinent articles. Findings regarding the nature of epilepsy etiologies, patient characteristics, tested language modalities, and language measures were compiled. Data mining focused on social network databases to obtain a set of relevant language-related posts. The search yielded 66 articles. Epilepsy etiologies except temporal lobe epilepsy and older adults were underrepresented. Most studies utilized aphasia tests and primarily assessed single-word productions; few studies included healthy control groups. Data mining revealed several posts regarding epilepsy-related language problems, including word retrieval, reading, writing, verbal memory difficulties, and negative effects of epilepsy treatment on language. Our findings underscore the need for future specification of the integrity of language in epilepsy, particularly with respect to discourse and high-level language abilities. Increased awareness of epilepsy-related language issues and understanding the patients' perspectives about their language concerns will allow researchers and speech-language pathologists to utilize appropriate assessments and improve quality of care.

It has been proven that physical morbidity is related to psychiatric illness. Some physical illnesses are more related to psychiatric morbidity compared to others. Epilepsy is considered one of them, as patients who suffer from epilepsy has disturbances of consciousness and this leads to a variety of psychological disturbance in addition to the psychological and social impact of the illness. To identify risk factors and psychiatric morbidity in epilepsy, in order to try to manage it and improve outcome of this illness and enhance quality of life. Patients who were referred to the department of Neurology at Mosul Teaching hospital from primary care centres between October 2012 and February 2013 and consented to participate in the study, were checked and if they fulfilled the criteria for the diagnosis of epilepsy, they were interviewed and their sociodemographic data were recorded, the hospital anxiety and depression questionnaire (HAD) was administered. Results were input in a computer programme and software statistical programme Minitab version 14.1 was utilised to analyse these data. The whole sample was 100 patients. 55 females and 45 males were included. Mean age was 30 years. Mean duration of illness was 5.5 years. Mean HAD score was 17. Male patients were a little bit older but there was no statistically significant difference compared to females and they both scored similar HAD score. There was no difference between urban and rural population with regards to HAD score. The results showed statistically significant correlation between age and duration of the illness and HAD score. The present study showed that there is a correlation between epilepsy and psychiatric morbidity. It has confirmed that females are more affected compared to males, which is expected as compared to the general population. It has also confirmed that psychiatric morbidity is positively related to epilepsy as it showed that the duration of illness has increased the psychiatric morbidity

The RF is geographically the largest territory in the world with a population of 142 million. The study evaluated prevalence of epilepsy in older teenagers and adults in 14 regions of the RF with total population of 517,624 persons (about 0.34% of all the population of the RF). Study sites were located in both European (Western population) and Siberian (Eastern population) regions of Russia. We identified 1753 patients with established epilepsy (1033 men, 720 women) from available medical information sources. Epilepsy cases were evaluated by study neurologists or epileptologists; all the patients underwent EEG, one third - neuroimaging. The age adjusted prevalence of epilepsy, standardized to the European Standard Million was 3.40 (95%CI: 3.26-3.55) per 1000. Prevalence was higher among men-4.50 (95%CI: 4.25-4.76) than among women-2.52 (95%CI: 2.35-2.69) (p < 0.0001). Prevalence in the Eastern population was significantly higher than in the Western population. The highest prevalence was found in the age group 50-59 years. Localization-related (focal) epilepsies/epilepsy syndromes were diagnosed in the majority (81.6%). In about one-third of those with localization-related epilepsies etiology remained undetermined. Head injury was the main identified cause of epilepsy, followed by cerebrovascular disorders. The prevalence of epilepsy in the population ≥ 14 y.o. in Russia is consistent with results of the studies in adults in other European countries, although at lower end of the range. Age and gender trends are similar. Copyright © 2010 Elsevier B.V. All rights reserved.

Patients with epilepsy and those with psychogenic non-epileptic seizures (PNES) experience high levels of stress and stress is one of the most frequently self-identified seizure precipitants. Although stress is a multifaceted phenomenon, few studies have systematically examined its different components in patients with seizures. The aim of this study was therefore to describe diurnal patterns of psychological and physiological measures of stress in patients with epilepsy and patients with PNES, and explore their relationships to each other in order to improve our understanding of the mechanisms underlying stress and seizure occurrence in these patients. A range of stress markers including self-reported stress, salivary cortisol, and heart rate variability (HRV) were explored in adult patients with refractory epilepsy (N=22) and those with PNES (N=23) undergoing three- to five-day video-telemetry. A diurnal pattern was observed in the physiological measures, characterized by higher levels of physiological arousal in the mornings and lower levels at night in both patients with epilepsy and PNES. The physiological measures (cortisol and HRV) were associated with each other in patients with epilepsy; no close relationship was found with self-reported stress in either of the two patient groups. The findings contribute to and expand on previous studies of the patterns of stress in patients with seizures. The results also indicate a discrepancy between patients' physiological responses and their subjective stress perceptions, suggesting that simple self-reports cannot be used as a proxy of physiological arousal in patients with seizures and stress. Stress in these patient groups should be studied using a combination of complementary measures. Copyright © 2017 Elsevier Inc. All rights reserved.

We examined if children of mothers with epilepsy had normal intelligence, speculating that either epilepsy or its therapy might affect this parameter. In a population-based cohort study in Norway, information on maternal epilepsy reported to the Medical Birth Registry of Norway, 1967-1979 was linked to information on 18-19-year-old men's intellectual ability and anthropometric measures ascertained by the Norwegian Conscripts Service, 1984-1999. The standardized intelligence test (IQ score) was reported as single-digit standard scores with values from 1 to 9. No individual information on antiepileptic drug therapy was available. Mean IQ score was lower in 1,207 conscripts whose mothers had epilepsy reported on the birth notification form, as compared with 316,554 conscripts of mothers without epilepsy; 4.8 (standard deviation 1.8) versus 5.2(1.8), p < 0.001, respectively. This difference remained after adjustment for maternal education, maternal age, birth order, marital status, year of birth, and weight and length at birth. When comparing men with and without reported maternal epilepsy, the odds ratio of having an IQ score < or = 3 was 1.6 (95% confidence interval: 1.4-1.8), which was unaffected by adjustment for confounding factors. Mean height among conscripts of mothers with and without epilepsy measured 178.6 and 179.9 cm, respectively, a difference of 1.3 cm (p < 0.001). We observed that almost 20 years after birth, maternal epilepsy was associated with reduced IQ score and also shorter adult height in male offspring. We do not know whether these findings will persist when epilepsy is better treated with the newer and safer generation of antiepileptic drugs.

This study aimed to clarify the effect of statins on preventing the risk of postradiation epilepsy. We performed a retrospective analysis of neurological nasopharyngeal carcinoma patients with a history of radiotherapy. Patients with a history of epilepsy before radiation and those who received prophylactically antiepileptic treatment were excluded. The demographic and clinical data of these patients were collected through chart review. We used Kaplan-Meier analysis (log-rank test) to examine the effect of statins on epilepsy-free survival. Cox regression analysis was utilized to identify independent predictive variables. Our study included 532 patients (405 males and 127 females) with a mean follow-up of 28.1 months. During follow-up, 471 (88.5%) patients developed radiation-induced brain necrosis (RN). Within a mean latency of 24.1 months, 88 (16.5%) patients experienced epilepsy, of whom 27 (27 of 88, 30.7%) patients suffered from epilepsy before the diagnosis of RN. Thirty-six (36 of 88, 40.9%) cases of epilepsy occurred after RN onset, and in 22 cases (22 of 88, 25.0%) epilepsy was the first presentation of RN. Three patients suffered from epilepsy but did not have RN. Eighty-eight patients in our cohort were treated with statins because of hyperlipidemia or prevention of cardiocerebrovascular diseases, of whom six (6.8%) developed epilepsy, whereas in those without statin, the epileptic rate was 18.5%. Log-rank test found that there was a significant difference in epilepsy-free survival between patients who used statins and those who did not (p = 0.016). After adjusting for confounding variables, multivariate Cox regression analysis revealed that statin use could still significantly reduce the risk of epilepsy after radiation (hazard ratio = 0.36, 95% confidence interval = 0.15-0.82, p = 0.015). However, for the patients who already suffered from RN, statin treatment did not lower the risk of post-RN epilepsy. Early statin use may reduce the risk of

Objective: To determine outcome after epilepsy surgery in patients with normal preoperative magnetic resonance imaging (MRI). Methods: 24 adult and paediatric patients with normal preoperative MRIs were studied. They underwent epilepsy surgery between 1994 and 2001 and had at least one year of follow up. Results: At the most recent follow up, nine patients (37%) were seizure-free and 18 (75%) had at least a 90% reduction in seizure frequency with weekly or monthly seizures. Seizure freedom was not significantly different after resections in frontal (5/9) or temporal regions (4/13) (p = 0.24, Fisher's exact test), or among patients with or without localising features on EEG, PET, or ictal SPECT. Subdural grids, used in 15 of 24 patients, helped tailor resections but were not associated with differences in outcome. Histopathology showed cortical dysplasia in 10 patients (42%), non-specific findings in 13 (54%), and hippocampal sclerosis in one (4%). Cortical dysplasia was seen in seven patients with frontal resection (78%) and non-specific findings in nine (69%) with temporal resection. Seizure outcome did not differ on the basis of location of resection or histopathology. Conclusions: While these results were less favourable than expected for patients with focal epileptogenic lesions seen on MRI, they represented worthwhile improvement for this patient population with high preoperative seizure burden. In this highly selected group, no single test or combination of tests further predicted postoperative seizure outcome. PMID:15834032

Auditory temporal processing is the main feature of speech processing ability. Patients with temporal lobe epilepsy, despite their normal hearing sensitivity, may present speech recognition disorders. The present study was carried out to evaluate the auditory temporal processing in patients with unilateral TLE. The present study was carried out on 25 patients with epilepsy: 11 patients with right temporal lobe epilepsy and 14 with left temporal lobe epilepsy with a mean age of 31.1years and 18 control participants with a mean age of 29.4years. The two experimental and control groups were evaluated via gap-in-noise and duration pattern sequence tests. One-way ANOVA was run to analyze the data. The mean of the threshold of the GIN test in the control group was observed to be better than that in participants with LTLE and RTLE. Also, it was observed that the percentage of correct responses on the DPS test in the control group and in participants with RTLE was better than that in participants with LTLE. Patients with TLE have difficulties in temporal processing. Difficulties are more significant in patients with LTLE, likely because the left temporal lobe is specialized for the processing of temporal information. Copyright © 2016 Elsevier Inc.

Epilepsy surgery is the most efficacious therapeutic modality for patients with medically refractory focal epilepsies, but surgical failures remain a challenge to the epilepsy treatment team. The aim of present study was to evaluate the postoperative outcome of patients who underwent reoperation after a failed epilepsy surgery on the temporal lobe. We systematically analyzed the results of comprehensive preoperative evaluations before the first surgery, and before and after reoperation in 17 patients with drug resistant temporal lobe epilepsies. Overall, 13 of 17 patients (76.5%) improved after reoperation: five patients (29.4%) were completely seizure free after reoperation (median duration 60months, range 12-72); six patients (35.3%) were seizure free at least 12month before observation points (median duration 120.5months, range 35-155) and two patients (11.8%) had a decrease in seizure frequency. Four patients (23.5%) remained unchanged with respect to seizure frequency and severity. There was no correlation between the improvement in seizure outcome after reoperation and other clinical data except of the history of traumatic brain injury (TBI). The patients who had no history of TBI improved after reoperation, compared to patients with TBI (p=0.044). The postoperative seizure outcome of patients with incongruent Video-EEG results before the first surgery (p=0.116) and before reoperation (p=0.622) was not poorer compared to patients with congruent Video-EEG results. Reoperation can considerably improve the operative outcome of the first failed epilepsy surgery in patients with drug resistant temporal lobe epilepsies. Epilepsy centres should be encouraged to report the results of failed epilepsy surgeries. Copyright © 2012 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

The impact of lesions and epilepsy on personality and mood in patients with symptomatic epilepsy: a pre- to postoperative follow-up study.

PubMed

Witt, Juri-Alexander; Hollmann, Karsten; Helmstaedter, Christoph

2008-12-01

To discern more static and lesion based from more dynamic epilepsy-driven features of depression and personality in focal symptomatic epilepsy, change in personality and mood was examined as a function of focus lateralization and seizure outcome after epilepsy surgery. Self-reported personality and depression were assessed before and 1 year after epilepsy surgery in 151 consecutive patients with temporal (N=125) or extratemporal lobe epilepsy (N=26). At baseline only depressed mood (31%) and introversion (38%) appeared elevated, the first being more frequent in right lateralized epilepsies, the latter being pronounced in temporal lobe epilepsy. After surgery, seizure freedom was associated with a significant change in neuroticism as well as with improvements in mood and symptoms of an organic psycho-syndrome. Differential changes were observed for seizure-free left (enhanced emotional stabilization) versus right temporal resected patients (decreased anxiety and impulsivity, less vegetative symptoms). Apart from elevated depression and introversion scores which showed some relation to pathology, no major deviant personality features could be discerned. While seizure freedom related improvements may indicate both epilepsy and reactively driven behavioral changes, the differential recovery observed in seizure-free left versus right temporal resected patients indicate epilepsy-specific behavioral dysfunction.

Mitochondrial disorders and epilepsy.

Desguerre, I; Hully, M; Rio, M; Nabbout, R

Mitochondrial respiratory chain defects (RCD) often exhibit multiorgan involvement, affecting mainly tissues with high-energy requirements such as the brain. Epilepsy is frequent during the evolution of mitochondrial disorders (30%) with different presentation in childhood and adulthood in term of type of epilepsy, of efficacy of treatment and also in term of prognosis. Mitochondrial disorders can begin at any age but the diseases with early onset during childhood have generally severe or fatal outcome in few years. Four age-related epileptic phenotypes could be identified in infancy: infantile spasms, refractory or recurrent status epilepticus, epilepsia partialis continua and myoclonic epilepsy. Except for infantile spasms, epilepsy is difficult to control in most cases (95%). In pediatric patients, mitochondrial epilepsy is more frequent due to mutations in nDNA-located than mtDNA-located genes and vice versa in adults. Ketogenic diet could be an interesting alternative treatment in case of recurrent status epilepticus or pharmacoresistant epilepsy. Epileptic seizures increase the energy requirements of the metabolically already compromised neurons establishing a vicious cycle resulting in worsening energy failure and neuronal death.

Headache is a frequently heard complaint that can strongly influence quality of life. This is probably even more so in people with a chronic illness. Knowing that headache, and especially migraine, is more frequent among epilepsy patients, the knowledge concerning this problem has been studied among Dutch neurologists. Seven hundred and seventy two neurologists, working in 89 hospitals and two tertiary epilepsy clinics were asked to participate. Using a questionnaire, neurologists were surveyed on different subjects, e.g. whether they thought current headaches are more frequent in people with epilepsy than in the general population, their interest for epilepsy and how many patients with epilepsy visited their polyclinic per month. In total, 334 questionnaires were returned (response rate of 43%) of which 18 were excluded. One third of neurologists responded affirmatively that current headaches are more prevalent among people with epilepsy and eight percent knows that this is, more specified, migraine. The number of years of experience does not influence knowledge on headaches in epilepsy patients. The interest in epilepsy and the number of epilepsy patients per month on the polyclinic does. These results show that the occurrence of headache in people with epilepsy is underestimated by Dutch neurologists. This leaves an often bothersome and potentially treatable condition underexposed.

Temporal lobe epilepsy (TLE) is a frequent form of focal intractable epilepsy in adults, but the specific mechanism underlying the epileptogenesis of TLE is still unknown. Human leukocyte immunoglobulin-like receptor B2 (LILRB2) (the murine homolog gene called paired immunoglobulin-like receptor B, or PirB), participates in the process of synaptic plasticity and neurite growth in the central nervous system (CNS), suggesting a potential role of LILRB2 in epilepsy. However, the expression pattern of LILRB2 and the downstream molecular signal in intractable TLE remains poorly understood. In the present study, western blotting and immunohistochemistry results showed that LILRB2 expression was upregulated in the temporal neocortex of patients with TLE. Moreover, protein levels of LILRB2 negatively correlated with the frequency of seizures in TLE patients. In the pilocarpine-induced C57BL/6 mouse model, PirB upregulation in the hippocampus began 12h after status epilepticus (SE), reached a peak at 7days and then maintained a significantly high level until day 60. Similarly, we found a remarkable increase in PirB expression at 1day, 7days and30days post-SE in the temporal cortex. Double-labeled immunofluorescence showed that LILRB2/PirB were highly expressed in neurons and astrocytes but not microglia. In addition, protein levels of POSH, SHROOM3, ROCK1 and ROCK2, the important downstream factors of the LILRB2 pathway, were significantly increased in the epileptic foci of TLE patients and located on the NeuN-positive neurons and GFAP-positive astrocytes. Taken together, our results indicate that LILRB2/PirB may be involved in the process of TLE. Copyright © 2016 Elsevier Inc. All rights reserved.

Due to differences in epilepsy types and surgery, economic evaluations of epilepsy treatment in adults cannot be extrapolated to children. We evaluated the cost-effectiveness of epilepsy surgery compared to medical treatment in children with intractable epilepsy. Decision tree analysis was used to evaluate the cost-effectiveness of surgery relative to medical management. Fifteen patients had surgery and 15 had medical treatment. Cost data included inpatient and outpatient costs for the period April 2007 to September 2009, physician fee, and medication costs. Outcome measure was percentage seizure reduction at one-year follow-up. Incremental cost-effectiveness ratio (ICER) was assessed. Sensitivity analysis was performed for different probabilities of surgical and medical treatment outcomes and costs, and surgical mortality or morbidity. More patients managed surgically experienced Engel class I and II outcomes compared to medical treatment at one-year follow-up. Base-case analysis yielded an ICER of $369 per patient for each percentage reduction in seizures for the surgery group relative to medical group. Sensitivity analysis showed robustness for the different probabilities tested. Surgical treatment resulted in greater reduction in seizure frequency compared to medical therapy and was a cost-effective treatment option in children with intractable epilepsy who were evaluated for epilepsy surgery and subsequently underwent surgery compared to continuing medical therapy. However, larger sample size and long-term follow-up are needed to validate these findings. Copyright © 2011 Elsevier B.V. All rights reserved.

The purpose of this study was to evaluate health care expenditures among elderly patients with epilepsy in the United States. We performed an analysis of weighted 37 738 607 US participants aged 65 years to estimate health care expenditures in the elderly with and without epilepsy using the Medical Expenditure Panel Survey Household Component, with 2003-2014 data. Unadjusted health care expenditures were estimated. Independent health care expenditures were estimated, using a 2-part model. We identified 416 496 (1.1%) older individuals with epilepsy. Comorbidities were more prevalent among older individuals with epilepsy versus younger individuals. Mean unadjusted yearly medical cost of epilepsy in elderly patients with epilepsy was $18 712 (95% confidence interval [CI] = $15 947-$21 476) during the pooled period 2003-2014, which was nearly double the equivalent cost in elderly subjects without epilepsy at $10 168 (95% CI = $9925-$10 410). Mean unadjusted annual medical cost of epilepsy in the elderly increased by $2135 from $15 850 (95% CI = $10 668-$21 032) in 2003-2006 to $17 985 (95% CI = $13 710-$22 260) in 2011-2014. Adjusted mean total health care expenditures per person per year for elderly patients with epilepsy were $12 526 in 2003-2006, $13 423 in 2007-2010, and $10 569 in 2011-2014. Adjusted incremental health care costs associated with epilepsy in the elderly accrued by $4595 (95% CI = $2399-$6791) when compared to elderly subjects without epilepsy. We estimated the mean annual aggregate cost of epilepsy at $7.8 billion to the US population. Epilepsy is common among elderly individuals, and health care expenditures among this growing group are 2 times higher than in those without epilepsy.

Limited information is available on the risks of epilepsy after surgery in patients receiving general or neuraxial anaesthesia. Using Taiwan's National Health Insurance Research Database, we identified 1,478,977 patients aged ≥ 20 years who underwent surgery (required general or neuraxial anaesthesia with hospitalisation for more than one day) between 2004 and 2011. We selected 235,066 patients with general anaesthesia and 235,066 patients with neuraxial anaesthesia using a frequency-matching procedure for age and sex. We did not study those with co-existing epilepsy-related risk factors. The adjusted rate ratios (RRs) and 95% confidence intervals (CIs) of newly diagnosed epilepsy 1 year after surgery associated with general anaesthesia were analysed in the multivariate Poisson regression model. The one-year incidence of postoperative epilepsy for patients with general anaesthesia and neuraxial anaesthesia were 0.41 and 0.32 per 1000 persons, respectively, and the corresponding RR was 1.27 (95%CI 1.15-1.41). The association between general anaesthesia and postoperative epilepsy was significant in men (RR = 1.22; 95%CI 1.06-1.40), women (RR = 1.33; 95%CI 1.15-1.55) and 20-39-year-old patients. The risk of postoperative epilepsy increased in patients with general anaesthesia who had co-existing medical conditions and postoperative complications. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

The present study aimed to assess the impact of the ketogenic diet on arterial morphology and endothelial function of the big vessels of the neck and on cardiac diastolic function, in a cohort of epileptic children and young adults treated with the ketogenic diet. Patients were recruited based on the following inclusion criteria: (1) patients who were or had been on the ketogenic diet for a time period of at least six months. Each patient underwent measurement of carotid intima media thickness, carotid artery stiffness, echocardiography, and diastolic function assessment. Patients with drug resistant epilepsy, matched for number, age and sex and never treated with ketogenic diet, were recruited as controls. The population study was composed by 43 epilepsy patients (23 males), aged between 19 months and 31 years (mean 11 years). Twenty-three patients were or had been treated with ketogenic diet, and 20 had never been on it (control group). Subjects treated with the ketogenic diet had higher arterial stiffness parameters, including AIx and β-index and higher serum levels of cholesterol or triglycerides compared to those who had never been on the diet (control group) (p<0.001). Arterial stiffness is increased in children and young adults treated with the ketogenic diet, before the increase of the intima media thickness. This supports that arterial stiffness is an early marker of vascular damage. Copyright © 2013 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

[Economic aspects of epilepsy].

Argumosa, A; Herranz, J L

2000-06-01

The economic magnitude of epilepsy is determined by its effect on the employment status of the patients, the cost of drug treatment for them and the healthcare system and the repercussion worldwide. Studies of the cost of the disease show that it has economic importance due to the sum of the direct and indirect costs caused by it. In the case of epilepsy, the results of studies in various countries led to the creation of a Commission on Economic Aspects of Epilepsy. The lack of epidemiological studies regarding epilepsy in Spain may explain the lack of publications on this subject in our country. The percentage of the total cost due to antiepileptic drugs is considerable and will probably increase in the future. The pharmaco-economic evaluation made by cost-benefit, cost-effectiveness, cost-usefulness analysis and studies to minimize costs should serve to use healthcare resources in the most effective manner and justify the rational use of the new antiepileptic drugs. The economic impact of epilepsy is added to the repercussion of the disease itself on the patient and his family. The different distribution of costs in children and adults with epilepsy suggest the need for intervention at an early age to try to reduce the long term economic and personal repercussions. The pharmaco-economic evaluation of the new antiepileptic drugs will make it clear whether their considerable cost is worth paying for their greater effectivity.

Evaluating subjective cognitive impairment in the adult epilepsy clinic: Effects of depression, number of antiepileptic medications, and seizure frequency.

Subjective cognitive complaints are a frequent concern of patients with epilepsy. The Aldenkamp-Baker Neuropsychological Assessment Schedule (ABNAS) is a patient-reported scale validated to measure adverse cognitive effects of antiepileptic drugs (AEDs). The goals of this study were to identify predictors of patient-reported cognitive dysfunction and to assess the relationship between subjective and objective cognitive impairment. The Cleveland Clinic Knowledge Program Data Registry was used to identify adult patients seen in outpatient epilepsy clinic from January to May 2015 and who completed the following scales: ABNAS for subjective cognitive impairment, Patient Health Questionnaire (PHQ-9) for depression, Generalized Anxiety Disorder 7-item (GAD-7) scale, Quality of Life in Epilepsy (QOLIE-10), and EuroQOL five dimensions questionnaire (EQ-5D) for health-related quality of life. Topiramate (TPM) was considered a high-risk medication for cognitive impairment. Patients were categorized into groups based on total ABNAS score: subjective cognitive impairment (ABNAS>15; N=270) and no subjective cognitive impairment (ABNAS≤15; N=400). Multivariable logistic regression models were constructed to identify independent predictors of subjective cognitive impairment. In a subset of patients who had neuropsychological testing within 6months of completing the ABNAS (N=60), Pearson correlations and multivariable logistic regression models, controlling for number of AEDs, depression, and anxiety, assessed the relationship between subjective cognitive impairment and objective cognitive performance on measures of intelligence, attention/working memory, verbal fluency, naming, processing speed, manual dexterity, visuomotor processing, and verbal memory. Forty percent of patients in the overall sample (N=270/670) reported cognitive impairment. The variables most strongly associated with subjective cognitive impairment were PHQ-9 score, number of AEDs, and seizure frequency. In

Pediatric epilepsies are a group of disorders with a broad phenotypic spectrum that are associated with great genetic heterogeneity, thus making sequential single-gene testing an impractical basis for diagnostic strategy. The advent of next-generation sequencing has increased the success rate of epilepsy diagnosis, and targeted resequencing using genetic panels is the a most cost-effective choice. We report the results found in a group of 87 patients with epilepsy and developmental delay using targeted next generation sequencing (custom-designed Haloplex panel). Using this gene panel, we were able to identify disease-causing variants in 17 out of 87 (19.5%) analyzed patients, all found in known epilepsy-associated genes (KCNQ2, CDKL5, STXBP1, SCN1A, PCDH19, POLG, SLC2A1, ARX, ALG13, CHD2, SYNGAP1, and GRIN1). Twelve of 18 variants arose de novo and 6 were novel. The highest yield was found in patients with onset in the first years of life, especially in patients classified as having early-onset epileptic encephalopathy. Knowledge of the underlying genetic cause provides essential information on prognosis and could be used to avoid unnecessary studies, which may result in a greater diagnostic cost-effectiveness.

Prevalence and long-term outcome of epilepsy in tuberous sclerosis complex (TSC) is reported to be variable, and the reasons for this variability are still controversial. We reviewed the clinical characteristics of patients with TSC who were regularly followed since 2000 at the San Paolo Multidisciplinary Tuberous Sclerosis Centre in Milan, Italy. From patient charts we collected data about age at epilepsy onset, seizure frequency and seizure type, history of infantile spasms (IS), epileptic syndrome, evolution to refractory epilepsy or to seizure freedom and/or medication freedom, electroencephalography (EEG) features, magnetic resonance imaging (MRI) findings, cognitive outcome, and genetic background. Among the 160 subjects (120 adults and 40 children), 116 (72.5%) had epilepsy: 57 (35.6%) were seizure-free, and 59 (36.9%) had drug-resistant epilepsy. Most seizure-free patients had a focal epilepsy (89.5%), with 54.4% of them drug resistant for a period of their lives. Epilepsy onset in the first year of life with IS and/or focal seizures was characteristic of the drug-resistant group of patients, as well as cognitive impairment and TSC2 mutation (p < 0.05). A small group of patients (7 patients, 4.4%) experienced a seizure only once; all of them had normal cognition. Although epilepsy management can be challenging in TSC, more than one third of patients had their seizures controlled: through monotherapy in 56% and by polytherapy in 32%. Moreover, 12% of the patients became seizure-free and were off medication. Identifying predictive features of epilepsy and cognitive outcome can ensure better management for patients with TSC and delineate genotype-phenotype correlations.

We investigated causes of death in children and young adults with epilepsy by using data from the U.S. National Child Death Review Case Reporting System (NCDR-CRS), a passive surveillance system composed of comprehensive information related to deaths reviewed by local child death review teams. Information on a total of 48,697 deaths in children and young adults 28 days to 24 years of age, including 551 deaths with epilepsy and 48,146 deaths without epilepsy, was collected from 2004 through 2012 in 32 states. In a proportionate mortality analysis by official manner of death, decedents with epilepsy had a significantly higher percentage of natural deaths but significantly lower percentages of deaths due to accidents, homicide, and undetermined causes compared with persons without epilepsy. With respect to underlying causes of death, decedents with epilepsy had significantly higher percentages of deaths due to drowning and most medical conditions including pneumonia and congenital anomalies but lower percentages of deaths due to asphyxia, weapon use, and unknown causes compared with decedents without epilepsy. The increased percentages of deaths due to pneumonia and drowning in children and young adults with epilepsy suggest preventive interventions including immunization and better instruction and monitoring before or during swimming. State-specific and national population-based mortality studies of children and young adults with epilepsy are recommended. PMID:25794682

First-line treatment for epilepsy is antiepileptic drug and requires an interdisciplinary approach and enduring commitment and adherence from the patient and family for successful outcome. Despite adherence to antiepileptic drugs, refractory epilepsy occurs in approximately 30% of children with epilepsy, and surgical treatment is an important intervention to consider. Surgical management of pediatric epilepsy is highly effective in selected patients with refractory epilepsy; however, an evidence-based protocol, including best methods of presurgical imaging assessments, and neurodevelopmental and/or behavioral health assessments, is not currently available for clinicians. Surgical treatment of epilepsy can be critical to avoid negative outcomes in functional, cognitive, and behavioral health status. Furthermore, it is often the only method to achieve seizure freedom in refractory epilepsy. Although a large literature base can be found for adults with refractory epilepsy undergoing surgical treatment, less is known about how surgical management affects outcomes in children with epilepsy. The purpose of the review was fourfold: (1) to evaluate the available literature regarding presurgical assessment and postsurgical outcomes in children with medically refractory epilepsy, (2) to identify gaps in our knowledge of surgical treatment and its outcomes in children with epilepsy, (3) to pose questions for further research, and (4) to advocate for a more unified presurgical evaluation protocol including earlier referral for surgical candidacy of pediatric patients with refractory epilepsy. Despite its effectiveness, epilepsy surgery remains an underutilized but evidence-based approach that could lead to positive short- and long-term outcomes for children with refractory epilepsy.

Although it is known that epilepsy and spirituality are related, spirituality in epilepsy has received relatively little clinical and scientific attention. Therefore, we investigated which epilepsy-related factors are associated with high spirituality in Korean adults living with epilepsy. This cross-sectional study was conducted in two university hospitals in Korea. Spirituality was assessed using the 6-item Spirituality Self-Rating Scale (SSRS). The participants were categorized into high and low spirituality groups according to the median SSRS score. The presumptive seizure onset zone was determined based on the clinical semiology, electroencephalography, and magnetic resonance imaging findings. Of the 180 participants, 61.7% declared that they had a religious affiliation. The median SSRS score was 15 (interquartile range: 7, 22). The high spirituality subgroup consisted of 92 (51.1%) participants. In the univariate analyses, the high spirituality group was significantly associated with female sex (p<0.05), older age (p<0.01), longer epilepsy duration (p<0.05), polytherapy (p<0.05), complex partial seizure (p<0.05), levetiracetam or topiramate usage (p<0.05), and a right-lateralized seizure onset zone. The multiple logistic regression analysis identified right hemispheric lateralization as the only independent factor associated with high spirituality (odds ratio: 2.410, 95% confidence interval: 1.051-5.528, p<0.05). High spirituality may be associated with right hemispheric lateralization but not with the temporal localization of the seizure onset zone in Korean adults with epilepsy.

Correlates of stigma in adults with epilepsy: A systematic review of quantitative studies.

PubMed

Baker, David; Eccles, Fiona J R; Caswell, Helen L

2018-06-01

The aim of this review was to identify quantitative correlates, predictors, and outcomes of stigma in adults with epilepsy living in Western countries. To identify relevant literature, four academic databases (PsycINFO, CINAHL, PubMed, and Scopus) were systematically searched using key terms related to stigma and epilepsy. Thirty-three research papers reporting findings from 25 quantitative studies of correlates of stigma in epilepsy were identified. The findings suggest that stigma can be predicted by demographic, illness-related, and psychosocial factors, although associations were found to be highly culturally specific. Outcomes of stigma in people with epilepsy were replicated more consistently across cultures, and its impact was significant. Detrimental effects included both worse physical health, including less effective management of the condition, and reduced psychological well-being, including difficulties such as depression and anxiety. Educational initiatives and therapeutic interventions that aim to address stigma in people with epilepsy are recommended; however, these need to be culturally informed to ensure that they are valid and effective.

Most patients with epilepsy report a desire for more information on the disease and possible treatments than provided by clinicians. In the past two decades, many have turned to the internet for information, but this information is of variable accuracy and objectivity. We assessed the prevalence of internet use for gathering information about epilepsy and patient satisfaction in a sample of epilepsy patients in China. A cross-sectional multicenter study was conducted using a standard anonymous questionnaire that gathered demographic information and information on internet use. The reasons for using the internet, the sites visited, general satisfaction with the information provided, and impact on self-management were investigated. Of the 780 patients studied, 288 (36.9%) had internet access and 73% of these participants reported searching for general information on epilepsy, 64% for treatment information, 30% to prepare for actual hospital visits, 12% to communicate with other patients, 5% for purchasing products for epilepsy management, and 6% for other reasons. All of the participants used search engines. However, only 6% browsed websites recommended by their doctors and 96.8% thought the information gathered from other sites was inadequate. The internet holds great potential for informing epileptic patients about their disease and to seek social support. Governments, hospitals, doctors, and internet service providers must collaborate to ensure that this information is reliable and beneficial. Copyright © 2013 British Epilepsy Association.

Previous studies suggest that treatment for obstructive sleep apnea (OSA) in patients with epilepsy can improve seizure control. We investigated the effect of positive airway pressure (PAP) therapy on seizures in adults with epilepsy referred to the Cleveland Clinic for polysomnography (PSG) from 1997 to 2010. Seizure outcome at baseline and 1 year later was compared in patients with no OSA (apnea-hypopnea index [AHI] <5), patients with PAP-treated OSA, and patients with untreated OSA. One hundred thirty-two subjects (age: 40.2±13 (18-76) years, 65.4% female) were included. Seventy-six (57.6%) subjects had OSA; of these, 43 (56.6%) were on PAP therapy, and 33 (43.4%) were not on PAP therapy (either PAP-intolerant or refused therapy). Of the group with PAP-treated OSA, 83.7% were adherent (use ≥4 h/night at least 5 nights/week). The percentage of subjects with ≥50% seizure reduction and the mean percentage of seizure reduction were significantly greater in the group with PAP-treated OSA (73.9%; 58.5%) than in subjects with untreated OSA (14.3%; 17.0%). There were significantly more subjects with successful outcomes (with ≥50% seizure reduction or seizure-free at both baseline and follow-up) in the group with PAP-treated OSA (83.7%) than in the groups with no OSA (53.6%) and untreated OSA (39.4%). After adjusting for age, gender, body mass index, AHI, and epilepsy duration, we found that the odds of successful outcomes in subjects in the group with PAP-treated OSA were 9.9 and 3.91 times those of the groups with untreated OSA and no OSA, respectively. The group with PAP-treated OSA had 32.3 times the odds of having a ≥50% seizure reduction compared with the group with untreated OSA and 6.13 times compared with the group with no OSA. Positive airway pressure therapy appears to produce beneficial effects on seizures in adult patients with epilepsy and OSA. Copyright © 2014 Elsevier Inc. All rights reserved.

Posterior cortex epilepsy surgery is rarely performed and is associated with a high number of surgical failures, partly because accurate localization of the epileptogenic zone in the posterior part of the brain is extremely difficult. We present the characteristics as well as the surgical outcome and its determinants of a cohort of 208 consecutive patients (adults/children: 125/83) operated on for drug-resistant posterior cortex epilepsy at the "Claudio Munari" Epilepsy Surgery Centre, Milan between May 1996 and May 2013 (mean postsurgical follow-up: 9.6years). In addition, we highlight the differences in anatomoelectroclinical features and outcome between (i) patients who necessitated an invasive preoperative evaluation and those who proceeded directly to surgery and (ii) adults and children. Mean age at epilepsy onset was 6.8years (91.4% with onset before 14years of age). A high seizure frequency was reported by 51% of subjects, interictal and ictal EEG features were localizing in 16% and 28% of cases, and 86% of patients had a positive, judged as more or less informative, MRI. Invasive presurgical evaluation by stereoelectroencephalography was performed in 54% of patients; explorations may schematically be grouped in three main implantation patterns. Globally, 70% of subjects achieved seizure freedom, and further, 10% achieved Engel class II, with the patients operated on in childhood achieving significantly better postsurgical results in terms of seizure freedom and drug discontinuation. Duration of epilepsy represented the most consistent predictor of surgical outcome, with early surgery being correlated with higher chances of surgical success. Therefore, we recommend an early surgical referral in cases of pharmacoresistant posterior cortex seizures. Furthermore, we suggest that surgical failure might be predicted very early, namely within the first 6 postoperative months. We conclude that surgical management of posterior cortex epilepsy may attain excellent

Frontal lobe epilepsy.

PubMed

Kellinghaus, Christoph; Lüders, Hans O

2004-12-01

Frontal lobe epilepsy accounts for only 10-20% of the patients in surgical series, but the incidence in non-surgical patient cohorts seems to be much higher. The typical clinical presentation of the seizures includes contralateral clonic movements, uni- or bilateral tonic motor activity as well as complex automatism. The yield of surface EEG may be limited due to the difficulty in detection of mesial or basal foci, and the patient may be misdiagnosed as having non-epileptic events. In addition, in patients with mesial frontal foci the epileptiform discharges may be mislateralized ("paradoxical lateralization"). Therefore, epilepsy surgery has been commonly considered as less promising in patients with frontal lobe epilepsy. However, the advent of sophisticated neuroimaging techniques, particularly MRI with epilepsy-specific sequences, has made it possible to delineate the epileptogenic lesion and detect a specific etiology, in an increasing number of patients. Thus, the success rate of epilepsy surgery in frontal lobe epilepsy is currently comparable to temporal lobe epilepsy, if the candidates are carefully selected. Patients with frontal lobe epilepsy who do not respond to anticonvulsive medication, and who are not eligible for epilepsy surgery may benefit from alternative approaches such as electrical brain stimulation.

Cognitive difficulties are common in epilepsy. Beyond reducing seizures and adjusting antiepileptic medications, no well-validated treatment exists in adults. Methylphenidate is used effectively in children with epilepsy and attention-deficit/hyperactivity disorder, but its effects in adults have not been systematically evaluated. We hypothesized that methylphenidate can safely improve cognition in adults with epilepsy. We detail here the open-label follow-up to a double-blind, placebo-controlled, single-dose study. Thirty epilepsy patients entered a 1-month open-label methylphenidate trial after a double-blind phase. Doses were titrated according to clinical practice and patient tolerance, ranging 20-40 mg/day. Primary measures included: Conners' Continuous Performance Test (CPT), Symbol-Digit Modalities Test (SDMT), and Medical College of Georgia Memory Test (MCG). Secondary measures were: Beck Depression Inventory, 2nd Edition (BDI-II), Beck Anxiety Inventory, Apathy Evaluation Scale (AES), Stimulant Side-Effect Checklist, Adverse Events Profile, Quality of Life in Epilepsy-89 (QOLIE-89), and seizure frequency. Fourteen healthy, nonmedicated controls were tested concurrently. Twenty-eight participants with epilepsy (13 men/15 women) completed the trial. Withdrawals occurred due to anxiety (n = 1) and fatigue (n = 1). Mean age was 36.4 years (range = 20-60). Epilepsy types were: focal (n = 21), generalized (n = 6), or unclassified (n = 1). Mean epilepsy duration was 12.3 years. Mean baseline seizure frequency was 2.8/month. There were significant improvements on methylphenidate for SDMT, MCG, CPT (the ability to discriminate between targets and nontargets [d'] hits, hit reaction time standard deviation, omissions, and commissions), and QOLIE subscales (energy/fatigue, attention/concentration, memory, and language; paired t tests; p ≤ 0.002). BDI-II and additional subscales also improved, at a lower level of statistical significance. Effect

Qatar is a small country on the Eastern coast of the Arabian Peninsula. Its population is a unique mixture of native citizens and immigrants. We aimed to describe the features of epilepsy in Qatar as such information is virtually lacking from the current literature. We summarized information retrospectively collected from 468 patients with epilepsy seen through the national health system adult neurology clinic. Epilepsy was classified as focal in 65.5% of the cases and generalized in 23%. Common causes of epilepsy were as follows: stroke (9%), hippocampal sclerosis (7%), infections (6%), and trauma (6%). Sixty-six percent of patients were receiving a single antiepileptic drug, with levetiracetam being the most frequently prescribed drug (41% of subjects). When the patients were divided by geographical background, remote infections caused the epilepsy in 15% of Asian patients (with neurocysticercosis accounting for 10%) but only in 1% of Qatari and 3% of Middle East/North African subjects (with no reported neurocysticercosis) (p<0.001). Cerebrovascular and neurodegenerative etiologies were the most prominent in Qataris, accounting for 14% (p=0.005) and 4% (p=0.03) of cases, respectively. The choice of antiepileptic drugs varied also according to the regional background, but the seizure freedom rate did not, averaging at 54% on the last clinic visit. To our knowledge, this is the first detailed information about epilepsy in Qatar. The geographical origin of patients adds to the heterogeneity of this disorder. Neurocysticercosis should be in the etiological differential diagnosis of epilepsy in patients coming from Southeast Asian countries, despite the fact that it is not endemic to Qatar. The choice of antiepileptic drugs is influenced by the availability of individual agents in the patients' native countries but had no bearing on the final seizure outcome.

The main aim of the European Study SPOKE (Sanofi-Synthelabo Programme for Outcome Knowledge of Epilepsy) designed by the Department of Neurosciences, Walton Hospital in Liverpool and the Centre for Health Services Research at the University of Newcastle upon Tyne, England, was to describe levels of knowledge about epilepsy among people with epilepsy and their families. It was equally important to identify gaps in understanding the most important aspects of the illness as well as to identify characteristics of people who score poorly on the Epilepsy Knowledge Questionnaire (EKQ). Another aim was to consider the implications of identified gaps in knowledge for future educational and psychosocial interventions. The study was conducted in 10 European countries and included 6156 people with epilepsy and 6506 members of their families. Results presented here relate to data for Poland only, where the examined population consisted of 1028 patients with epilepsy. 1033 questionnaires were returned by carers. Over 40% of all respondents had frequent seizures, and one third were seizure free. Scores on the Epilepsy Knowledge Questionnaire were high for the majority of respondents, but generally lower than in most of the countries. With reference to some aspects of illness important gaps in knowledge have been demonstrated. For example, it was shown that a significant number of respondents provided incorrect answers to questions relating to aspects of the etiology of epilepsy and administration of antiepileptic drug medication. There were a number of significant differences between the profiles of high and low scorers on the EKQ; high scorers were likely to have spent longer on education, have lower scores on the impact of epilepsy scale and report better adjustment to their epilepsy. The results of the study once again underline the importance of continued information among patients with epilepsy and their families in order to achieve.

To assess the yield of diagnostic exome sequencing (DES) and to characterize the molecular findings in characterized and novel disease genes in patients with epilepsy. In an unselected sample of 1,131 patients referred for DES, overall results were compared between patients with and without epilepsy. DES results were examined based on age of onset and epilepsy diagnosis. Positive/likely positive results were identified in 112/293 (38.2%) epilepsy patients compared with 210/732 (28.7%) patients without epilepsy (P = 0.004). The diagnostic yield in characterized disease genes among patients with epilepsy was 33.4% (105/314). KCNQ2, MECP2, FOXG1, IQSEC2, KMT2A, and STXBP1 were most commonly affected by de novo alterations. Patients with epileptic encephalopathies had the highest rate of positive findings (43.4%). A likely positive novel genetic etiology was proposed in 14/200 (7%) patients with epilepsy; this frequency was highest in patients with epileptic encephalopathies (17%). Three genes (COQ4, DNM1, and PURA) were initially reported as likely positive novel disease genes and were subsequently corroborated in independent peer-reviewed publications. DES with analysis and interpretation of both characterized and novel genetic etiologies is a useful diagnostic tool in epilepsy, particularly in severe early-onset epilepsy. The reporting on novel genetic etiologies may further increase the diagnostic yield.Genet Med 18 9, 898-905.

SH3 and multiple ankyrin (ANK) repeat domain 3 (SHANK3) is a synaptic scaffolding protein enriched in the postsynaptic density of excitatory synapses. SHANK3 plays an important role in the formation and maturation of excitatory synapses. In the brain, SHANK3 directly or indirectly interacts with various synaptic molecules including N-methyl-D-aspartate receptor, the metabotropic glutamate receptor (mGluR), and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor. Previous studies have shown that Autism spectrum disorder is a result of mutations of the main SHANK3 isoforms, which may be due to deficit in excitatory synaptic transmission and plasticity. Recently, accumulating evidence has demonstrated that overexpression of SHANK3 could induce seizures in vivo. However, little is known about the role of SHANK3 in refractory temporal lobe epilepsy (TLE). Therefore, we investigated the expression pattern of SHANK3 in patients with intractable temporal lobe epilepsy and in pilocarpine-induced models of epilepsy. Immunofluorescence, immunohistochemistry, and western blot analysis were used to locate and determine the expression of SHANK3 in the temporal neocortex of patients with epilepsy, and in the hippocampus and temporal lobe cortex of rats in a pilocarpine-induced epilepsy model. Double-labeled immunofluorescence showed that SHANK3 was mainly expressed in neurons. Western blot analysis confirmed that SHANK3 expression was increased in the neocortex of TLE patients and rats. These results indicate that SHANK3 participates in the pathology of epilepsy.

Selected patients with intractable focal epilepsy who have failed a previous epilepsy surgery can become seizure-free with reoperation. Preoperative evaluation is exceedingly challenging in this cohort. We aim to investigate the diagnostic value of two noninvasive approaches, magnetoencephalography (MEG) and ictal single-photon emission computed tomography (SPECT), in patients with failed epilepsy surgery. We retrospectively included a consecutive cohort of patients who failed prior resective epilepsy surgery, underwent re-evaluation including MEG and ictal SPECT, and had another surgery after the re-evaluation. The relationship between resection and localization from each test was determined, and their association with seizure outcomes was analyzed. A total of 46 patients were included; 21 (46%) were seizure-free at 1-year followup after reoperation. Twenty-seven (58%) had a positive MEG and 31 (67%) had a positive ictal SPECT. The resection of MEG foci was significantly associated with seizure-free outcome (p = 0.002). Overlap of ictal SPECT hyperperfusion zones with resection was significantly associated with seizure-free outcome in the subgroup of patients with injection time ≤20 seconds(p = 0.03), but did not show significant association in the overall cohort (p = 0.46) although all injections were ictal. Patients whose MEG and ictal SPECT were concordant on a sublobar level had a significantly higher chance of seizure freedom (p = 0.05). MEG alone achieved successful localization in patients with failed epilepsy surgery with a statistical significance. Only ictal SPECT with early injection (≤20 seconds) had good localization value. Sublobar concordance between both tests was significantly associated with seizure freedom. SPECT can provide essential information in MEG-negative cases and vice versa. Our results emphasize the importance of considering a multimodal presurgical evaluation including MEG and SPECT in all patients with a

Epilepsy is a chronic neurological disorder that results in recurring seizures and can have a significant adverse effect on health-related quality of life (HRQL). The Neuro-QoL measurement initiative is an NINDS-funded system of patient-reported outcome measures for neurology clinical research, which was designed to provide a precise and standardized way to measure HRQL in epilepsy and other neurological disorders. Using mixed-method and item response theory-based approaches, we developed generic item banks and targeted scales for adults and children with major neurological disorders. This paper provides empirical results from a clinical validation study with a sample of adults diagnosed with epilepsy. One hundred twenty-one people diagnosed with epilepsy participated, the majority of which were male (62%) and Caucasian (95%), with a mean age of 47.3 (SD=16.9). Baseline assessments included Neuro-QoL short forms and general and external validity measures. The Neuro-QoL short forms that are not typically found in other epilepsy-specific HRQL instruments include Stigma, Sleep Disturbance, Emotional and Behavioral Dyscontrol, and Positive Affect and Well-Being. Neurology Quality-of-Life short forms demonstrated adequate reliability (internal consistency range=.86-.96; test-retest range=.57-.89). Pearson correlations (p<.01) between Neuro-QoL forms of emotional distress (anxiety, depression, stigma) and the QOLIE-31 Emotional Well-Being subscale were in the moderate-to-strong range (r's=.66, .71 and .53, respectively), as were relations with the PROMIS Global Mental Health subscale (r's=.59, .74 and .52, respectively). Moderate correlations were observed between Neuro-QoL Social Role Performance and Satisfaction and the QOLIE-31 Social Function (r's=.58 and .52, respectively). In measuring aspects of physical function, the Neuro-QoL Mobility and Upper Extremity forms demonstrated moderate associations with the PROMIS Global Physical Function subscale (r's=.60 and .61

Autonomic dysfunction has frequently been reported in autoimmune encephalitis associated with seizures and there is growing evidence that epilepsy patients may display neuronal autoantibodies (NAAb). The aim of this study was to investigate the frequency of NAAb in epilepsy patients with peri-ictal autonomic findings. Fifty-eight patients (37 women/21 men; average age of 34.2 ± 9.9 years and epilepsy duration of 19.1 ± 9.6 years) who had at least one video-EEG recorded focal or secondary generalized seizure with clear-cut documented peri-ictal autonomic findings, or consistently reported seizures with autonomic semiology, were included. NAAb were tested by RIA or cell based assays. NAAb were present in 17 of 58 (29.3%) patients. Among seropositive patients, antibodies were directed against N-methyl-D-aspartate receptor (NMDAR) in 5 (29%), contactin-associated protein-like 2 (CASPR2) in 5 (29%), uncharacterized voltage gated potassium channel (VGKC)-complex antigens in 3 (18%), glutamic acid decarboxylase (GAD) in 2 (12%), glycine receptor (GLYR) in one (6%) and type A gamma aminobutyric acid receptor (GABAAR) in one patient (6%). Peri-ictal gastrointestinal manifestations, piloerection, ictal fever, urinary urge, and cough occurred more commonly in the seropositive group. The prevalences of psychotic attacks and status epilepticus were significantly increased in the seropositive group. Seropositivity prevalence in our patient group with peri-ictal autonomic findings is higher than other previously reported epilepsy cohorts. In our study, ictal fever-VGKC-complex antibody and pilomotor seizure-GABAAR antibody associations were documented for the first time. Chronic epilepsy patients with peri-ictal autonomic semiology, history of status epilepticus and psychotic disorder may benefit from autoantibody screening.

Dimensions of the epilepsy foundation concerns index.

We performed principal component analysis (PCA) of the Epilepsy Foundation Concerns Index scale in 189 patients undergoing evaluation for epilepsy surgery. We identified a five-factor solution in which there were no varimax-rotated factors consisting of fewer than two questions. Factor 1 reflects affective impact on enjoyment of life, Factor 2 reflects general autonomy concerns, Factor 3 reflects fear of seizure recurrence, Factor 4 reflects concern of being a burden to one's family, and Factor 5 reflects a perceived lack of understanding by others. Multiple regression using the Quality of Life in Epilepsy--89 question version; Minnesota Multiphasic Personality Inventory--2; Wechsler Adult Intelligence Scale--third edition; and verbal and visual memory tests as predictors demonstrated a different pattern of association with the factor and summary scores. We conclude that the Epilepsy Foundation Concerns Index is multidimensional, and using a global score based on all items may mask specific concerns that may be relevant when applied to individual patients.

Clinical characteristics of children and young adults with co-occurring autism spectrum disorder and epilepsy.

The association between autism spectrum disorder (ASD) and epilepsy has been described for decades, and yet we still lack the full understanding of this relationship both clinically and at the pathophysiologic level. This review evaluates the available data in the literature pertaining to the clinical characteristics of patients with autism spectrum disorder who develop epilepsy and, conversely, patients with epilepsy who develop autism spectrum disorder. Many studies demonstrate an increased risk of epilepsy in individuals with ASD, but rates vary widely. This variability is likely secondary to the different study methods employed, including the study population and definitions of the disorders. Established risk factors for an increased risk of epilepsy in patients with ASD include intellectual disability and female gender. There is some evidence of an increased risk of epilepsy associated with other factors such as ASD etiology (syndromic), severity of autistic features, developmental regression, and family history. No one epilepsy syndrome or seizure type has been associated, although focal or localization-related seizures are often reported. The age at seizure onset can vary from infancy to adulthood with some evidence of a bimodal age distribution. The severity and intractability of epilepsy in populations with ASD have not been well studied, and there is very little investigation of the role that epilepsy plays in the autism behavioral phenotype. There is evidence of abnormal EEGs (especially epileptiform abnormalities) in children with ASD even in the absence of clinical seizures, but very little is known about this phenomenon and what it means. The development of autism spectrum disorder in patients with epilepsy is less well studied, but there is evidence that the ASD risk is greater in those with epilepsy than in the general population. One of the risk factors is intellectual disability, and there is some evidence that the presence of a particular seizure

The risk of death is increased for persons with epilepsy. The literature on causes of death in epilepsy is based mainly on cohorts with epilepsy of mixed aetiologies. For clinical purposes and improved understanding of mortality in different epilepsies, more information is needed on mortality in epilepsies of specific causes. In poststroke epilepsy (PSE), seizures occur in a setting of vascular disease and high mortality rates. The extent to which epilepsy contributes to mortality in this patient group is poorly understood. We therefore aimed to describe causes of death (COD) in PSE on a national scale. A previously identified cohort of 7740 patients with epilepsy or seizures after a stroke in 2005-2010 was investigated. A total of 4167 deaths occurred before the end of 2014. The standardized mortality ratio for the study cohort was 3.56 (95% CI: 3.45-3.67). The main underlying causes of death were disorders of the circulatory system (60%) followed by neoplasms (12%). Diseases of the nervous system were the sixth leading underlying COD (3%), and epilepsy or status epilepticus was considered the underlying COD in approximately a similar proportion of cases as neurodegenerative disorders (0.9% and 1.1%, respectively). Epilepsy was considered a contributing COD in 14% of cases. Our findings highlight the importance of optimal management of vascular morbidity in patients with PSE. The large proportion of patients with epilepsy as a contributing COD indicate the need of high ambitions also regarding the management of seizures in patients with PSE.

Several studies have demonstrated that treatment with enzyme-inducing antiepileptic drugs is associated with increased serum lipid levels. Eslicarbazepine acetate (ESL) is a novel antiepileptic drug specifically designed with the objective to identify carbamazepine and oxcarbazepine analogues with favorable pharmacodynamic and pharmacokinetic profiles. The present study aimed to assess the changes in lipid profile and sodium levels in patients with epilepsy taking ESL as adjunctive therapy. This report describes a retrospective cohort study of 36 adult patients with epilepsy, taking ESL as an add-on treatment. The laboratory values assessed prior and after (range 6-18 months) ESL treatment were sodium levels, total cholesterol (TC), low (LDL) and high (HDL) density lipoproteins and triglycerides. TC and LDL values were significantly decreased already after at least six months of therapy with ESL (191.3±29.6 vs 179.7±29.2mg/dl, p <0.0001 and 114.58±22.7 vs 103.11±19.46mg/dl, p <0.0001 respectively). HDL values before and during ESL treatment were significantly increased (57.5± 9.1 vs 63.9±8.3mg/dl; p<0.0001). No statistically significant changes have been found in triglycerides and sodium values. Add-on therapy with ESL, in contrast to the negative effects observed with traditional older carboxamides, positively affects lipid metabolism profile in patients with epilepsy over an average follow-up of 11 months. Further research is needed to confirm the obtained results with a focus on a comprehensive assessment of the biochemical and molecular mechanisms involved.

Rapid advances in genetic research and increased use of genetic testing have increased the emphasis on genetic causes of epilepsy in patient encounters. Research in other disorders suggests that genetic causal attributions can influence patients' psychological responses and coping strategies, but little is known about how epilepsy patients and their relatives will respond to genetic attributions of epilepsy. We investigated the possibility that among members of families containing multiple individuals with epilepsy, depression, the most frequent psychiatric comorbidity in the epilepsies, might be related to the perception that epilepsy has a genetic cause. A self-administered survey was completed by 417 individuals in 104 families averaging 4 individuals with epilepsy per family. Current depression was measured with the Patient Health Questionnaire. Genetic causal attribution was assessed by three questions addressing the following: perceived likelihood of having an epilepsy-related mutation, perceived role of genetics in causing epilepsy in the family, and (in individuals with epilepsy) perceived influence of genetics in causing the individual's epilepsy. Relatives without epilepsy were asked about their perceived chance of developing epilepsy in the future, compared with the average person. Prevalence of current depression was 14.8% in 182 individuals with epilepsy, 6.5% in 184 biologic relatives without epilepsy, and 3.9% in 51 individuals married into the families. Among individuals with epilepsy, depression was unrelated to genetic attribution. Among biologic relatives without epilepsy, however, prevalence of depression increased with increasing perceived chance of having an epilepsy-related mutation (p = 0.02). This association was not mediated by perceived future epilepsy risk among relatives without epilepsy. Depression is associated with perceived likelihood of carrying an epilepsy-related mutation among individuals without epilepsy in families containing

Sudden unexpected deaths comprise the most important and worthy investigation case profiles in both neurology and forensic medicine. Epilepsy, which is one of the neuropathological causes of sudden unexpected deaths, is an important disorder having mysterious aspects. The aim of this study is to make common the points of view between neurology and forensic medicine experts and to discuss the features of the findings together with the related clinical hypotheses, leading to the differential diagnosis of sudden unexpected death in epilepsy (SUDEP) by presenting autopsy findings and available medical data of patients who had a prior diagnosis of epilepsy. In Istanbul, the cases of 20334 autopsied patients who were referred to The Ministry of Justice Council of Forensic Medicine between 2007 and 2011 were identified from the complete forensic autopsy data of the city and were retrospectively reviewed. Patients who had a prior diagnosis of epilepsy were included. Both descriptive and inferential statistical analyses were performed through the parameters of demographical data, physical properties, incident features, macroscopic-microscopic autopsy findings, and cause of death initially for all cases and then separately for SUDEP cases. Among the 20334 patients, 112 were determined to have a prior diagnosis of epilepsy. A possible macroscopic and/or microscopic epileptic focus was present in 23 (20.5%) of these 112 cases. The cause of death was determined to be SUDEP in 40 (35.7%) cases, while it could not be determined in 28 (25%) cases. Among patients whose death cause was considered as SUDEP, the male-to-female ratio was 1.1:1, while the mean age was 31.5±13.9 years in males and 29.6±12.9 years in females. The presence of hypertrophy and myocardial scar tissue findings in the microscopic examination were significantly more frequent among patients determined to have died from cardiovascular diseases compared to patients in the SUDEP group (p=0.001 for each finding

Childhood maltreatment has been shown to be a risk factor for the development of psychiatric disorders. Although the prevalence of psychiatric disorders is high in epilepsy patients, it is unknown if childhood maltreatment experiences are elevated compared to the normal population and if early maltreatment is a risk factor for current psychiatric comorbidities in epilepsy patients. This is the main purpose of this study. Structured interviews were used to assess current Axis I diagnoses in 120 epilepsy patients from a tertiary Epilepsy Center (34 TLE patients, 86 non-TLE patients). Childhood maltreatment in the family and peer victimization were assessed with validated questionnaires. Patients' maltreatment scores were compared with those of a representative matched control group. Logistic regression analysis was conducted to assess the potential impact of childhood maltreatment on current psychiatric comorbidity in epilepsy patients. Compared to a matched control group, epilepsy patients had higher emotional and sexual maltreatment scores. Patients with a current psychiatric diagnosis reported more family and peer maltreatment than patients without a psychiatric disorder. Family maltreatment scores predicted the likelihood of a current psychiatric disorder. TLE patients did not differ from non-TLE patients according to maltreatment experiences and rates of current psychiatric disorders. Our findings suggest that in epilepsy patients emotional and sexual childhood maltreatment is experienced more often than in the normal population and that early maltreatment is a general risk factor for psychiatric comorbidities in this group.

Persons with epilepsy experience déjà vu phenomena with or without seizure recognition. Déjà vu experiences are also common mental phenomena in nonclinical individuals. The purpose of this study was to clarify two forms of déjà vu experiences in persons with epilepsy. Déjà vu experiences of 312 patients with epilepsy and 402 nonclinical individuals were evaluated using the Inventory of Déjà vu Experiences Assessment. In the patients with epilepsy, characteristics of déjà vu experiences with seizure recognition (SR form) were compared with those experiences with no seizure recognition (NSR form). The incidence (63.1%) of déjà vu experiences in patients with epilepsy was significantly lower than that (76.1%) of nonclinical individuals (chi(2)=14.2, P=0.000). Among the patients with epilepsy, 55.6% had the NSR form and 24.0% had the SR form. Those with the NSR form manifested fewer psychopathological characteristics than did those with the SR form. Patients tended to view the SR form more negatively (i.e., frightened, uncomfortable, or disturbed) than the NSR form. The NSR form was significantly associated with idiopathic generalized epilepsies, less frequent antiepileptic drug administration, and no mesial temporal sclerosis. Although there was a significant association between the frequency of the SR form and patients' habitual seizures, the frequency of the NSR form was not associated with the frequency of the patients' habitual seizures. Persons with epilepsy experience two forms of déjà vu which are differently associated with their seizure recognition. Copyright 2010 Elsevier Inc. All rights reserved.

Epilepsy is characterized by spontaneous recurrent seizures and temporal lobe epilepsy (TLE) is the most common serious neurological example of acquired and frequent epilepsy. Oxidative stress is recognized as playing a contributing role in several neurological disorders, and most recently have been implicated in acquired epilepsies. The MTs occur in several brain regions and may serve as neuroprotective proteins against reactive oxygen species causing oxidative damage and stress. The main aim of this work was to describe the immunohistochemical localization of MT in the specimens derived from the patients affected by TLE. Histopathological examination showed NeuN, GFAP and MT immunopositive cells that were analyzed for determinate in hippocampal and parietal cortex samples. An increase in the reactive gliosis associated with increased MT expression was observed in patients with TLE. Copyright © 2016 Elsevier Ltd. All rights reserved.

This study aims to investigate the serum adiponectin, interleukin (IL)-6 and oxidative stress in epilepsy patients who are refractory or non-refractory to treatments. The study comprised 31 refractory epilepsy, 29 well-controlled epilepsy patients and control group including 29 healthy individuals. The serum adiponectin, IL-6, total antioxidant status (TAS), total oxidant status levels (TOS) and oxidative stress index (OSİ) were determined. The mean serum adiponectin and TAS levels were significantly lower in the refractory epilepsy patients than in the healty controls, and mean IL-6, TOS and OSİ levels were significantly higher. The serum adiponectin, IL-6, TAS, TOS and OSI levels were not significantly different between the well-controlled epilepsy patients and the healthy controls. The mean serum IL-6 and oxidative stress levels in refractory epilepsy patients were higher and the serum adiponectin level was lower than the healthy control group. These findings may be associated with an increased risk of seizures, atherosclerosis and cardiovascular disease in refractory epilepsy patients. Copyright © 2018 British Epilepsy Association.

Epilepsy is a concealable stigmatizing condition. We investigated the factors predicting disclosure management behavior in Korean adults with newly diagnosed epilepsy. This longitudinal multicenter study included Korean adults with newly diagnosed epilepsy. Using statistical analyses, we determined at the end of a 1-year follow-up whether Disclosure Management Scale (DMS) scores were predicted by demographic, clinical, and psychosocial variables, including felt stigma, stress coping style, personality traits, social support, and experienced discrimination from society. Of a total of 121 participants, 69% reported that they often or sometimes kept their diagnosis a secret from others and rarely or never talked to others about their epilepsy. The average DMS score was 5.8 (SD=2.9, range 0-11). In univariate analyses, DMS scores were significantly associated with an emotion-focused coping style (r=0.320, p<0.001), social support (r=-0.185, p<0.05), and experienced discrimination (p<0.05). Emotion-focused coping was the only independent predictor of a higher DMS score. Felt stigma, personality traits, and seizure freedom were not related to the DMS score. Two-thirds of Korean adults with newly diagnosed epilepsy often or sometimes keep their epilepsy a secret. Emotion-focused coping is the most important predictor of concealment of epilepsy diagnosis at the end of a 1-year follow-up, although social support and episodes of experienced discrimination are also associated with disclosure management strategies.

Cognitive comorbidity at epilepsy onset reflects disease severity and provides a baseline estimate of reserve capacities with regard to the effects of epilepsy and its treatment. Given the high incidence of epilepsy at an older age, this study analyzed objective and subjective cognition as well as quality of life in elderly patients with new-onset focal epilepsy before initiation of anti-epileptic treatment. A total of 257 untreated patients (60-95 years of age) with new-onset epilepsy underwent objective assessment of executive function (EpiTrack) and performed subjective ratings of cognition (Portland Neurotoxicity Scale) and quality of life (QoL; QOLIE-31). According to age-corrected norms, 58% of patients (N=257) demonstrated deficits in executive function; major determinants were cerebrovascular etiology, neurological comorbidity, and higher body mass index. Subjective ratings indicated deficits in up to 27% of patients. Self-perceived deficits were associated with neurological, cardiovascular, and/or psychiatric comorbidity, whereas poorer QoL was related to neurological comorbidity and female gender. Objectively assessed executive functions correlated with subjective social functioning, energy, motor function, and vigilance. We found a relatively high QoL, a low rate of subjective impairment, but a high incidence of objective executive deficits in untreated elderly patients with new-onset epilepsy. Neurological status and body mass index, rather than seizure frequency or severity, were risk factors for cognitive impairment. Given the relevance of cognition in the course of epilepsy and its treatment, routine screening before treatment initiation is highly recommended. © 2014 John Wiley & Sons A/S.

Introduction Epilepsy associated stigma remains a main hindrance to epilepsy care, especially in developing countries. In Africa, anti-epileptic drugs are available, affordable and effective. As of now, no community survey on epilepsy awareness and attitudes has been reported from this area Cameroon with a reported high prevalence of epilepsy. Methods To contribute data to the elaboration of the National Epilepsy Control Programme, we carried out a cross-sectional descriptive community survey of 520 households. We had as main objective to obtain baseline data on the knowledge, attitudes and practice of adults towards epilepsy in rural Cameroon, and compare with existing data. Results Most respondents had heard or read about epilepsy, knew someone who had epilepsy and had seen someone having a seizure. The most frequently cited cause of epilepsy was witchcraft. Most subjects believed epilepsy is contagious. Epilepsy was a form of madness or insanity to 33.5% of them. Only 54.9% of respondents would meet a medical doctor for the treatment. Most respondents would not permit equal employment opportunities, association and child's marriage to someone with epilepsy. Age, female sex and level of education were associated to negative attitudes (p<0.001). Conclusion Adults in Fundong are very acquainted with epilepsy but have many erroneous beliefs about the condition. Their attitudes are generally negative. The National Epilepsy Programme must insist on modes of transmission, treatment options and first aid measures during epileptic seizures. The elderly (>50 years) and those without any formal education should be the main targets during health information, education and communication programmes. PMID:23503525

Patients with epilepsy, including children, have an increased mortality rate when compared to the general population. Only few studies on causes of mortality in childhood epilepsy exist and pediatric SUDEP rate is under continuous discussion. To describe general mortality, incidence of sudden unexpected death in epilepsy (SUDEP), causes of death and age distribution in a pediatric epilepsy patient population. The study retrospectively examined the mortality and causes of death in 1974 patients with childhood-onset epilepsy at a tertiary epilepsy center in Denmark over a period of 9 years. Cases of death were identified through their unique civil registration number. Information from death certificates, autopsy reports and medical notes were collected. 2.2% (n = 43) of the patient cohort died during the study period. This includes 9 patients with SUDEP (8 SUDEP cases per 10,000 patient years). 9 patients died in the course of neurodegenerative disease and 28 children died of various causes. Epilepsy was considered drug resistant in more than 95% of the deceased patients, 90% were diagnosed with intellectual disability. Mortality of patients that underwent dietary epilepsy treatment was slightly higher than in the general cohort. There were no epilepsy-related deaths due to drowning. This study confirms that SUDEP must not be disregarded in the pediatric age group. The vast majority of SUDEP cases in this study displays numerous risk factors similar to those described in adult epilepsy patients. Including SUDEP, only 30% of the mortality was directly seizure related. Copyright © 2013 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

Subpial transection surgery for epilepsy.

2015-12-03

Nearly 30% of patients with epilepsy continue to have seizures in spite of using several antiepileptic drug (AED) regimens. Such patients are regarded as having refractory, or uncontrolled, epilepsy. No definition of uncontrolled, or medically refractory, epilepsy has been universally accepted, but for the purposes of this review, we will consider seizures as drug resistant if they have failed to respond to a minimum of two AEDs. It is believed that early surgical intervention may prevent seizures at a younger age, which, in turn, may improve the intellectual and social status of children. Many types of surgery are available for treatment of refractory epilepsy; one such procedure is known as subpial transection. To determine the benefits and adverse effects of subpial transection for partial-onset seizures and generalised tonic-clonic seizures in children and adults. We searched the Cochrane Epilepsy Group Specialised Register (29 June 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; May 2015, Issue 5) and MEDLINE (1946 to 29 June 2015). We imposed no language restrictions. We considered all randomised and quasi-randomised parallel-group studies, whether blinded or non-blinded. Two review authors (BK and SR) independently screened trials identified by the search. The same two review authors planned to independently assess the methodological quality of studies. When studies were identified for inclusion, one review author would have extracted the data, and the other would have verified the data. We found no relevant studies. We found no evidence to support or refute use of subpial transection surgery for patients with medically refractory epilepsy. Well-designed randomised controlled trials are needed to guide clinical practice.

To describe the social, clinical and use-patterns characteristics of medicinal marijuana use among patients with epilepsy (PWEs). Eighteen PWEs with prescriptions for medicinal marijuana from a Canadian adult-epilepsy clinic were included in this study. Eighteen patients had a prescription of medicinal marijuana from a total population of 800 PWEs in our center (2.2%). Mean age of patients was 30±7.4 (19-50) years. Twelve (67%) patients were males. Eleven (61%) patients had drug-resistant epilepsy. Eleven (61%) patients suffered a psychiatric comorbidity and reported the use of illicit substances or heavy alcohol or tobacco consumption. Only two (11%) patients were married; the rest of patients (89%) were single or divorced. The drug use pattern was similar among patients. All patients asked for marijuana permission in the epilepsy clinic. Most (83%) had a previous history of marijuana smoking, with a mean of 6.6±3 (1-15) years. The mean consumption dose was 2.05±1.8 (0.5-8) grams per day. Ten (56%) patients reported withdrawal seizure exacerbation when they stopped the marijuana. Only two patients (11%) reported side effects, and all patients found medicinal marijuana very helpful for seizure control and improvement of mood disorder. PWEs using medicinal marijuana have a common profile. They are usually young single men with drug-resistant epilepsy and psychiatric comorbidity. Most used marijuana before formal prescription and all believe the drug was effective on their seizure control. Because of the concurrent use of other antiseizure medications, it is complex to estimate the actual effect of marijuana.

BACKGROUND: Mood disorders have been described as the commonest psychiatric disorders in patients with temporal lobe epilepsy. Secondary depression in temporal lobe epilepsy could be interpreted either as an adjustment reaction to a chronic disease or as a limbic dysfunction. To clarify this issue, a controlled study of psychiatric disorders was conducted in different forms of epileptic and non-epileptic chronic conditions. METHODS: Twenty outpatients with temporal lobe epilepsy, 18 outpatients with juvenile myoclonic epilepsy--a primary generalised seizure disorder--20 matched type I diabetic patients, and 20 matched normal controls were assessed by a structured interview (SADS) and by self rating scales (Beck depression inventory (BDI) and the state and trait anxiety scales STAIX1 and STAIX2). RESULTS: Sixteen (80%) patients with temporal lobe epilepsy fulfilled the criteria for a psychiatric diagnosis at the SADS interview with a significantly higher frequency than patients with juvenile myoclonic epilepsy (22%) and diabetic patients (10%) (P < 0.0001). The most frequent disorder in temporal lobe epilepsy was a mood disorder: 11 (55%) patients with temporal lobe epilepsy had depression compared with three patients with juvenile myoclonic epilepsy and two diabetic patients (P < 0.001). Eight patients with temporal lobe epilepsy with an affective disorder also had a comorbid personality or anxiety disorder. Patients with temporal lobe epilepsy scored significantly higher on BDI, STAIX1, and STAIX2 than the three control groups (P < 0.001, P < 0.01, P < 0.001). CONCLUSIONS: Patients with temporal lobe epilepsy have a higher incidence of affective and personality disorders, often in comorbidity, than patients with juvenile myoclonic epilepsy and diabetic patients suggesting that these psychiatric disorders are not an adjustment reaction to a chronic disease but rather reflect a limbic dysfunction.

People with active epilepsy are those who reported being told that they have epilepsy or a seizure disorder and either take antiseizure medication or have had a seizure during the past 12months. We used combined 2010 and 2013 National Health Interview Survey (NHIS) data on US adults with active epilepsy to examine whether taking medications and seizure frequency differed by sex, age, race/ethnicity, and reported or imputed annual family income. Of adults with active epilepsy, 45.5% reported taking medication and having at least one seizure, 41.3% reported taking medication and having no seizures, and 13.2% reported not taking any medication and having at least one seizure. About one-half of adults with active epilepsy and seizures have annual family incomes of less than $25,000. Promoting self-management supports and improved access to specialty care may reduce the burden of uncontrolled seizures in adults with epilepsy. Published by Elsevier Inc.

The online PatientsLikeMe® Epilepsy Community allows patients with epilepsy to record, monitor, and share their demographic, disease, and treatment characteristics, providing valuable insights into patient perceptions and understanding of epilepsy. The objective of this retrospective analysis was to characterize the profile of users and their disease and identify factors predictive of poor health-related quality of life (HRQoL), while assessing the platform's potential in providing patient-reported data for research purposes. Data recorded (January 2010-November 2011) by Epilepsy Community members, with an epilepsy diagnosis and who reported >1 seizure, included the following: sociodemographic and disease characteristics, treatments, symptoms, side effects perceived as medication-related, seizure occurrence, and standardized questionnaires (Quality of Life in Epilepsy Inventory [QOLIE-31/P], EuroQoL 5-Dimensions Scale, 3 Levels [EQ-5D-3L], and Hospital Anxiety and Depression Scale [HADS]). Univariate and multivariate logistic regressions were conducted to identify predictors of poor HRQoL. During the study period, the Epilepsy Community comprised 3073 patients, of whom 71.5% were female, had a mean age of 37.8years, and had a mean epilepsy duration of 17.7years. The most frequently reported moderate/severe symptoms (n=2135) included memory problems (60.2%), problems concentrating (53.8%), and fatigue (50.0%). Medication-related side effects (n=639) included somnolence (23.2%), fatigue (17.2%), and memory impairment (13.8%). The QOLIE-31/P scores (n=1121) were significantly worse in patients who experienced a recent seizure. For QOLIE-31/P, highly predictive factors for poor HRQoL included the following: mild/moderate problems concentrating, depression, memory problems, treatment side effects, occurrence of tonic-clonic seizures, and epilepsy duration ≤1year. For EQ-5D-3L, highly predictive factors for poor HRQoL included the following: pain, depression, and

Purpose. To review the postoperative seizure outcomes of patients that underwent surgery for epilepsy at King Faisal Specialist Hospital & Research Centre (KFSHRC). Methods. A descriptive retrospective study for 502 patients operated on for medically intractable epilepsy between 1998 and 2012. The surgical outcome was measured using the ILAE criteria. Results. The epilepsy surgery outcome for temporal lobe epilepsy surgery (ILAE classes 1, 2, and 3) at 12, 36, and 60 months is 79.6%, 74.2%, and 67%, respectively. The favorable 12- and 36-month outcomes for frontal lobe epilepsy surgery are 62% and 52%, respectively. For both parietal and occipital epilepsy lobe surgeries the 12- and 36-month outcomes are 67%. For multilobar epilepsy surgery, the 12- and 36-month outcomes are 65% and 50%, respectively. The 12- and 36-month outcomes for functional hemispherectomy epilepsy surgery are 64.2% and 63%, respectively. According to histopathology diagnosis, mesiotemporal sclerosis (MTS) and benign CNS tumors had the best favorable outcome after surgery at 1 year (77.27% and 84.3%, resp.,) and 3 years (76% and 75%, resp.,). The least favorable seizure-free outcome after 3 years occurred in cases with dual pathology (66.6%). Thirty-four epilepsy patients with normal magnetic resonance imaging (MRI) brain scans were surgically treated. The first- and third-year epilepsy surgery outcome of 17 temporal lobe surgeries were (53%) and (47%) seizure-free, respectively. The first- and third-year epilepsy surgery outcomes of 15 extratemporal epilepsy surgeries were (47%) and (33%) seizure-free. Conclusion. The best outcomes are achieved with temporal epilepsy surgery, mesial temporal sclerosis, and benign CNS tumor. The worst outcomes are from multilobar surgery, dual pathology, and normal MRI.

In this article, we review the current best evidence for the treatment of depression in patients with epilepsy. Depression is a common epilepsy comorbidity, but it is often unrecognized. The most important step in appropriately managing mood disorders in this population is making the diagnosis. Clinical vigilance and routine use of a validated screening tool can improve detection and quality of care. As is increasingly the case for the general population, persons with epilepsy are often interested in exploring alternative therapies for chronic conditions, including depression. Unfortunately, the benefit of complementary and alternative therapies for depression currently is largely unproven for persons with a seizure history, although an early study of exercise for mild depression has shown some benefit. Concerns about drug interactions, side effects, and expense may be barriers to the prescription of antidepressant medications for people requiring chronic antiepileptic drug (AED) therapy. For this reason, use of an AED with mood-stabilizing properties has appeal and may be appropriate for selected individuals with mild depressive symptoms. Undue fear of lowering seizure threshold should not preclude the prescription of an antidepressant medication, as the perceived risks are often overestimated and rarely outweigh the risk of leaving depression untreated. At present, the best evidence for efficacy and safety support the use of citalopram, sertraline, or mirtazapine as initial pharmacotherapy, whereas bupropion should be avoided. Start low, go slow, and use the lowest effective dose. Cognitive behavioral therapy is a valuable adjunct to antidepressant therapy in this population. For people with refractory partial epilepsy and refractory depression, vagus nerve stimulation has some appeal, in that it may be beneficial for both conditions, but the efficacy of vagus nerve stimulation in improving mood in patients with epilepsy remains unclear.

Seizure-related disability is an important contributor to health-related quality of life in persons with epilepsy. Yet, there is little information on patient-centered reports of seizure-related disability, as most studies focus on specific constructs of health-related disability, rather than epilepsy. We investigated how patients rate their own disability and how these ratings correlate with various clinical and sociodemographic characteristics. In a prospective cohort of 250 adults with epilepsy consecutively enrolled in the Neurological Disease and Depression Study (NEEDs), we obtained a broad range of clinical and patient-reported measures, including patients' ratings of seizure-related disability and epilepsy severity using self-completed, single-item, 7-point response global assessment scales. Spearman's correlation, multiple linear regression, and mediation analyses were used to examine the association between seizure-related disability scores and clinical and demographic characteristics of persons with epilepsy. The mean age and duration of epilepsy was 39.8 and 16.7 years, respectively. About 29.5% of the patients reported their seizures as "not at all disabling," whereas 5.8% of the patients reported them as "extremely disabling." Age, seizure freedom at 1 year, anxiety, and epilepsy severity were identified as statistically significant predictors of disability scores. The indirect effects of age and seizure freedom, attributable to mediation through epilepsy severity, accounted for 25.0% and 30.3% of the total effects of these determinants on seizure-related disability, respectively. Measuring seizure-related disability has heuristic value and it has important correlates and mediators that can be targeted for intervention in practice. Addressing modifiable factors associated with disability (e.g., seizure freedom and anxiety) could have a significant impact on decreasing the burden of disability in people with epilepsy.

This study evaluated trends in resource use and prescription patterns in patients with active epilepsy over a 10-year period at the same outpatient clinic of a German epilepsy center. We analyzed a cross-sectional patient sample of consecutive adults with active epilepsy over a 3-month period in 2013 and compared them with equally acquired data from the years 2003 and 2008. Using validated patient questionnaires, data on socioeconomic status, course of epilepsy, as well as direct and indirect costs were recorded. A total of 198 patients (mean age: 39.6±15.0years, 49.5% male) were enrolled and compared with our previous assessments in 2003 (n=101) and 2008 (n=151). In the 2013 cohort, 75.8% of the patients had focal epilepsy, and the majority were taking antiepileptic drugs (AEDs) (39.9% monotherapy, 59.1% polytherapy). We calculated epilepsy-specific costs of €3674 per three months per patient. Direct medical costs were mainly due to anticonvulsants (20.9% of total direct costs) and to hospitalization (20.8% of total direct costs). The proportion of enzyme-inducing anticonvulsants and 'old' AEDs decreased between 2003 and 2013. Indirect costs of €1795 in 2013 were mainly due to early retirement (55.0% of total indirect costs), unemployment (26.5%), and days off due to seizures (18.2%). In contrast to our previous findings from 2003 and 2008, our data show a stagnating cost increase with slightly reduced total costs and balanced direct and indirect costs in patients with active epilepsy. These findings are accompanied by an ongoing cost-neutral increase in the prescription of 'newer' and non-enzyme-inducing AEDs. However, the number and distribution of indirect cost components remained unchanged. Copyright © 2018 Elsevier Inc. All rights reserved.

Epilepsy is one of the most frequent neurological disorders, both in children and adult persons. About 0.5-1% of general population suffer from epilepsy, which means that about 50 million people in the world are affected. First years of life and very late adulthood are periods in human's life particularly predisposing to epilepsy. Repetitive epileptic seizures may cause many life-threatening situations and significantly lower patient's quality of life. To the most serious complications belong status epilepticus and sudden unexpected deaths due to epilepsy (SUDEP). Absences from work or school caused by seizures, difficulties in social life, frequent injuries and necessity of polytherapy are also important for patients. All these factors result in low self-esteem and poor quality of life. The main aim of the treatment was control of epileptic seizures. However, despite of new antiepileptic drugs developed almost every year, in one third of all patients with epilepsy seizures remain out of control. Those patients are regarded to have "drug-resistant epilepsy". Despite of significant scale of the problem, there is no one definition of the phenomenon. In the presented review the authors outline current definitions, recent opinions on pathogenesis and risk factors, and provide practical rules of pharmacotherapy of epilepsy, which should help to restrict drug-resistancy.

The increased risk for psychiatric disorders in epilepsy can be related to a number of clinical, psychosocial and biological factors. Due to the unpredictability of seizures and the possibility that they may occur at any time and in any place, patients with epilepsy may develop social phobia and may have feelings of worthlessness and stigma. These factors decrease their psychosocial function, self-efficacy, and quality of life and even increase the suicide rate. Considering the above-mentioned scientific data, the present study was designed to investigate phobia, self-esteem and depression status in patients with epilepsy. One hundred thirty-two patients (aged 21-52 years) and age- and gender-matched control group of 61 subjects (aged 25-60 years) were included in this study. All patients in both groups were administered the Liebowitz Social Anxiety Scale (LSAS), Coopersmith Self-Esteem Inventory (CSEI), and the Beck Depression Inventory (BDI). The mean ages of the patient group and the healthy controls were 29.66±11.3 and 32.16±7.99, respectively. There was no statistical significance between the two groups in terms of age and sex (p>0.05). BDI, LSAS and CSEI scores in the patient group were statistically significantly different than in the control group (p<0.05). Our results showed that social phobia, lower self-esteem and depression are important comorbid conditions in epileptic patients. Psychiatric disorders are usually underrecognized and undertreated in patients with epilepsy. Therefore, it is very important to identify and treat the psychiatric comorbid conditions in epilepsy because of their significant burden on patients' quality of life.

The purpose of this descriptive qualitative study was to understand the range of adult patients' views on whether and how to discuss the issue of SUDEP with patients with epilepsy and to clarify the optimal timing and formulation of this information. The principles of fundamental qualitative description informed all design decisions. Twenty-three patients aged 18-65years participated in the study. Nineteen participants completed a single one-on-one telephone interview, whereas four participants shared their experiences in a focus group. Directed content analysis was used to code, categorize, and synthesize the interview data. Of the 42 patients invited to participate, 23 participated in the study. There was consensus among all study participants that all individuals diagnosed with epilepsy should be informed about SUDEP. Many participants believed that the best time to be told about SUDEP was at diagnosis. The majority of participants suggested that the discussion about SUDEP should take place face to face, in a verbal discussion, followed by written information to take home. Several participants suggested that the information about SUDEP should not be shared separately but rather incorporated into the general information they received about epilepsy. Nearly all the participants felt that the information about SUDEP should come from the neurologist. Participants of this study wanted neurologists to inform patients about the risk of SUDEP, with the optimal timing and setting of SUDEP counseling determined on a case-by-case basis.

Current medications for patients with epilepsy work in only two of three patients. For those medications that do work, they only suppress seizures. They treat the symptoms, but do not modify the underlying disease, forcing patients to take these drugs with significant side effects, often for the rest of their lives. A major limitation in our ability to advance new therapeutics that permanently prevent, reduce the frequency of, or cure epilepsy comes from a lack of understanding of the disease coupled with a lack of reliable biomarkers that can predict who has or who will get epilepsy. The main goal of this report is to present a number of approaches for identifying reliable biomarkers from observing patients with brain disorders that have a high probability of producing epilepsy. A given biomarker, or more likely a profile of biomarkers, will have both a quantity and a time course during epileptogenesis that can be used to predict who will get the disease, to confirm epilepsy as a diagnosis, to identify coexisting pathologies, and to monitor the course of treatments. Additional studies in patients and animal models could identify common and clinically valuable biomarkers to successfully translate animal studies into new and effective clinical trials.

Standard mortality ratio for suicide in patients with epilepsy is three times higher than in the general population, and such a risk remains high even after adjusting for clinical and socioeconomic factors. It is thus important to have suitable screening instruments and to implement care pathways for suicide prevention in every epilepsy center. The aim of this study is to validate the use of the Neurological Disorder Depression Inventory for Epilepsy (NDDIE) as a suicidality-screening instrument. The study sample included adult patients with epilepsy assessed with the Mini International Neuropsychiatric Interview (MINI) and the NDDIE. A high suicidality risk according to the Suicidality Module of the MINI was considered the gold standard. Receiver operating characteristic analyses for NDDIE total and individual item scores were computed and subsequently compared using a nonparametric approach. The best possible cutoff was identified with the highest Youden index (J). Likelihood ratios were then computed, and specificity, sensitivity, positive, and negative predictive values calculated. The study sample consisted of 380 adult patients with epilepsy: 46.3% male; mean age was 39.4 ± 14.6; 76.7% had a diagnosis of focal epilepsy; mean age at onset of the epilepsy was 23.3 ± 17.5. According to the MINI, 74 patients (19.5%) fulfilled criteria for a major depressive episode and 19 (5%) presented a high suicidality risk. A score >2 (J = 0.751) for item 4 "I'd be better off dead" of the NDDIE displayed excellent psychometric properties with a good to excellent validity (area under the curve [AUC] 0.906; 95% confidence interval [CI] 0.820-0.992; p < 0.001), sensitivity 84.21% (95% CI 60.4-96.6), specificity 90.86% (95% CI 87.4-93.6), likelihood ratio+ 9.21 (95% CI 6.3-13.5), likelihood ratio- 0.17 (95% CI 0.06-0.50). Item 4 of the NDDIE has shown to be an excellent suicidality screening instrument allowing the development of further care pathways for suicide prevention in

Depression is relatively common among patients with epilepsy, but often with predominant atypical symptoms. Some antiepileptic drugs show positive psychotropic effects, but these are not always sufficient to stabilize mood in epilepsy patients. Antidepressants are recommended to treat atypical depression but are not always effective and present a certain risk of seizure provocation. Thus, new treatment options are welcome. Here, we describe three cases of refractory epilepsy with atypical depression in which olanzapine, contrary to its earlier reported proconvulsant effect, showed excellent antidepressant action and resulted in seizure control. Possible mechanisms of this action are discussed.

Is the first seizure epilepsy--and when?

PubMed

Lawn, Nicholas; Chan, Josephine; Lee, Judy; Dunne, John

Epilepsy has recently been redefined to include a single unprovoked seizure if the probability of recurrence is ≥60% over the following 10 years. This definition is based on the estimated risk of a third seizure after two unprovoked seizures, using the lower-limit 95% confidence interval (CI) at 4 years, and does not account for the initially high recurrence rate after first-ever seizure that rapidly falls with increasing duration of seizure freedom. We analyzed long-term outcomes after the first-ever seizure, and the influence of duration of seizure freedom on the likelihood of seizure recurrence, and their relevance to the new definition of epilepsy. Prospective analysis of 798 adults with a first-ever unprovoked seizure seen at a hospital-based first seizure clinic between 2000 and 2011. The likelihood of seizure recurrence was analyzed according to the duration of seizure freedom, etiology, electroencephalography (EEG), and neuroimaging findings. The likelihood of seizure recurrence at 10 years was ≥60% in patients with epileptiform abnormalities on EEG or neuroimaging abnormalities, therefore, meeting the new definition of epilepsy. However, the risk of recurrence was highly time dependent; after a brief period (≤12 weeks) of seizure freedom, no patient group continued to fulfill the new definition of epilepsy. Of 407 patients who had a second seizure, the likelihood of a third seizure at 4 years was 68% (95% CI 63-73%) and at 10 years was 85% (95% CI 79-91%). The duration of seizure freedom following first-ever seizure substantially influences the risk of recurrence, with none of our patients fulfilling the new definition of epilepsy after a short period of seizure freedom. When a threshold was applied based on the 10-year risk of a third seizure from our data, no first-seizure patient group ever had epilepsy. These data may be utilized in a definition of epilepsy after a first-ever seizure. Wiley Periodicals, Inc. © 2015 International League Against

Mobile health app developers increasingly are interested in supporting the daily self-care of people with chronic conditions. The purpose of this study was to review mobile applications (apps) to promote epilepsy self-management. It investigates the following: 1) the available mobile apps for epilepsy, 2) how these apps support patient education and self-management (SM), and 3) their usefulness in supporting management of epilepsy. We conducted the review in Fall 2017 and assessed apps on the Apple App Store that related to the terms "epilepsy" and "seizure". Inclusion criteria included apps (adult and pediatric) that, as follows, were: 1) developed for patients or the community; 2) made available in English, and 3) less than $5.00. Exclusion criteria included apps that were designed for dissemination of publications, focused on healthcare providers, or were available in other languages. The search resulted in 149 apps, of which 20 met the selection criteria. A team reviewed each app in terms of three sets of criteria: 1) epilepsy-specific descriptions and SM categories employed by the apps and 2) Mobile App Rating Scale (MARS) subdomain scores for reviewing engagement, functionality, esthetics, and information; and 3) behavioral change techniques. Most apps were for adults and free. Common SM domains for the apps were treatment, seizure tracking, response, and safety. A number of epilepsy apps existed, but many offered similar functionalities and incorporated few SM domains. The findings underline the need for mobile apps to cover broader domains of SM and behavioral change techniques and to be evaluated for outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

Autoimmune epilepsy is an underrecognized condition, and its true incidence is unknown. Identifying patients with an underlying autoimmune origin is critical because these patients' condition may remain refractory to conventional antiseizure medications but may respond to immunotherapy. To determine the prevalence of neurological autoantibodies (Abs) among adult patients with epilepsy of unknown etiology. Consecutive patients presenting to neurology services with new-onset epilepsy or established epilepsy of unknown etiology were identified. Serum samples were tested for autoimmune encephalitis Abs as well as thyroperoxidase (TPO) and glutamic acid decarboxylase 65 (GAD65) Abs. An antibody prevalence in epilepsy (APE) score based on clinical characteristics was assigned prospectively. Data were collected from June 1, 2015, to June 1, 2016. Presence of neurological Abs. A score based on clinical characteristics was assigned to estimate the probability of seropositivity prior to antibody test results. Good seizure outcome was estimated on the basis of significant reduction of seizure frequency at the first follow-up or seizure freedom. Of the 127 patients (68 males and 59 females) enrolled in the study, 15 were subsequently excluded after identification of an alternative diagnosis. Serum Abs suggesting a potential autoimmune etiology were detected in 39 (34.8%) cases. More than 1 Ab was detected in 7 patients (6.3%): 3 (2.7%) had TPO-Ab and voltage-gated potassium channel complex (VGKCc) Ab, 2 (1.8%) had GAD65-Ab and VGKCc-Ab, 1 had TPO-Ab and GAD65-Ab, and 1 had anti-Hu Ab and GAD65-Ab. Thirty-two patients (28.6%) had a single Ab marker. Among 112 patients included in the study, 15 (13.4%) had TPO-Ab, 14 (12.5%) had GAD65-Ab, 12 (10.7%) had VGKCc (4 of whom were positive for leucine-rich glioma-inactivated protein 1 [LGI1] Ab), and 4 (3.6%) had N-methyl-D-aspartate receptor (NMDAR) Ab. Even after excluding TPO-Ab and low-titer GAD65-Ab, Abs strongly suggesting an

Periodontal diseases are common in most populations and affect people at all socioeconomic levels. Evidence suggests that patients with epilepsy actually have higher risks of dental disease and increased oral health needs, but the frequency and consequences of poor controlled seizures on dental and periodontal health have not been reported before. We aimed to assess the impact of seizure frequency on periodontal status and oral hygiene in a sample of epilepsy patients. One hundred and nine consecutive patients treated for epilepsy at the outpatient clinic of our University Hospital were invited to take part in an oral examination to determine their periodontal disease status, together with a control group. In addition, seizure frequency and use of medication were documented. In logistic regression model, patients were significantly more susceptible to bad oral hygiene, gingivitis and periodontitis that controls (p<0.001); seizure frequency was significantly related to bad oral hygiene (p=0.010), gingivitis (p<0.001) and periodontitis (p<0.001). Tooth brushing habits and presence of caries were associated with oral health in patients group. Our study found a significant positive correlation between periodontal disease and seizure severity. Epilepsy patients need to focus more on their oral health and quality of oral hygiene. Copyright © 2013 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

Cognitive and perceptual comorbidities frequently accompany epilepsy and psychogenic nonepileptic events (PNEE). However, and despite the fact that perceptual function is built upon a multisensory foundation, little knowledge exists concerning multisensory function in these populations. Here, we characterized facets of multisensory processing abilities in patients with epilepsy and PNEE, and probed the relationship between individual resting-state EEG complexity and these psychophysical measures in each patient. We prospectively studied a cohort of patients with epilepsy (N=18) and PNEE (N=20) patients who were admitted to Vanderbilt's Epilepsy Monitoring Unit (EMU) and weaned off of anticonvulsant drugs. Unaffected age-matched persons staying with the patients in the EMU (N=15) were also recruited as controls. All participants performed two tests of multisensory function: an audio-visual simultaneity judgment and an audio-visual redundant target task. Further, in the cohort of patients with epilepsy and PNEE we quantified resting state EEG gamma power and complexity. Compared with both patients with epilepsy and control subjects, patients with PNEE exhibited significantly poorer acuity in audiovisual temporal function as evidenced in significantly larger temporal binding windows (i.e., they perceived larger stimulus asynchronies as being presented simultaneously). These differences appeared to be specific for temporal function, as there was no difference among the three groups in a non-temporally based measure of multisensory function - the redundant target task. Further, patients with PNEE exhibited more complex resting state EEG patterns as compared to their patients with epilepsy, and EEG complexity correlated with multisensory temporal performance on a subject-by-subject manner. Taken together, findings seem to indicate that patients with PNEE bind information from audition and vision over larger temporal intervals when compared with control subjects as well

Understanding the Patient Perspective of Seizure Severity in Epilepsy: Development of a Conceptual Model.

For patients with uncontrolled epilepsy, the severity and postictal sequelae of seizures might be more impactful than their frequency. Seizure severity is often assessed using patient-reported outcome (PRO) instruments; however, evidence of content validity for existing instruments is lacking. Our aim was to understand the real-life experiences of patients with uncontrolled epilepsy. A preliminary conceptual model was developed. The model was refined through (1) a targeted literature review of qualitative research on seizure severity; (2) interviews with four clinical epilepsy experts to evaluate identified concepts; and (3) qualitative interviews with patients with uncontrolled epilepsy, gathering descriptions of symptoms and impacts of epilepsy, focusing on how patients experience and describe "seizure severity." Findings were summarized in a final conceptual model of seizure severity in epilepsy. Twenty-five patients (12 who experienced primary generalized tonic-clonic seizures and 13 who experienced partial-onset seizures) expressed 42 different symptoms and 26 different impacts related to seizures. The final conceptual model contained a wide range of concepts related to seizure frequency, symptoms, and duration. Our model identified several new concepts that characterize the patient experience of seizure severity. A seizure severity PRO instrument should cover a wide range of seizure symptoms alongside frequency and duration of seizures. This qualitative work reinforces the notion that measuring seizure frequency is insufficient and that seizure severity is important in defining the patient's experience of epilepsy. This model could be used to assess the content validity of existing PRO instruments, or could support the development of a new one.

The relationship between myasthenia gravis (MG) and epilepsy has been rarely reported. As consequence, there are no specific guidelines for the management of these conditions when they mutually occur. We reported on three patients in whom epilepsy and MG are coexisting, but in different clinical settings. Two patients were treated with antiepileptic drugs which improved their symptoms. One patient has controlled the seizures after a successful anterior temporal lobectomy with no appreciable consequences to her MG. We discuss the difficulties in the management of epilepsy in patients with MG. In addition, we report on the first epileptic surgery in a MG patient, indicating that this surgical procedure as a safe option for the treatment of intractable epilepsy in patients with MG.

Epilepsy affects all age groups and is one of the most common and most disabling neurological disorders. The accurate diagnosis of seizures is essential as some patients will be misdiagnosed with epilepsy, whereas others will receive an incorrect diagnosis. Indeed, errors in diagnosis are common, and many patients fail to receive the correct treatment, which often has severe consequences. Although many patients have seizure control using a single medication, others require multiple medications, resective surgery, neuromodulation devices or dietary therapies. In addition, one-third of patients will continue to have uncontrolled seizures. Epilepsy can substantially impair quality of life owing to seizures, comorbid mood and psychiatric disorders, cognitive deficits and adverse effects of medications. In addition, seizures can be fatal owing to direct effects on autonomic and arousal functions or owing to indirect effects such as drowning and other accidents. Deciphering the pathophysiology of epilepsy has advanced the understanding of the cellular and molecular events initiated by pathogenetic insults that transform normal circuits into epileptic circuits (epileptogenesis) and the mechanisms that generate seizures (ictogenesis). The discovery of >500 genes associated with epilepsy has led to new animal models, more precise diagnoses and, in some cases, targeted therapies.

The purpose of the present study was to classify the imaging structural abnormalities of epileptic adult patients referred for magnetic resonance imaging (MR imaging) of the brain at Ramathibodi Hospital and to correlate with the clinical data and EEG. MR imaging of 91 adult epileptic patients (age ranging from 15-85 years old with an average of 36.90 years old) were retrospectively reviewed and classified into eight groups according to etiologies. Then clinical data and EEG correlations were analyzed using the Kappa analysis. All of the MR imaging of the brain were performed at Ramathibodi Hospital from January 2001 to December 2002. Secondary generalized tonic clonic seizure was the most common clinical presenting seizure type. Extra temporal lobe epilepsy was the most common clinical diagnosis. Of the thirty-three patients who underwent EEG before performing MR imaging, 17 had normal EEG From MR imaging, temporal lobe lesion was the main affected location and mesial temporal sclerosis (MTS) was the most common cause of the epilepsy in patients. For age group classification, young adult (15-34 years old) and adult (35-64 years old) age groups, MTS was the most common etiology of epilepsy with cortical dysplasia being the second most common cause for the first group and vascular disease for the latter group. For the older age group (> 64 years old), vascular disease and idiopathic cause were equally common etiologies. MRI, EEG findings, and clinical data were all concordant with statistical significance. MRI is the non-invasive modality of choice for evaluation of the epileptic patients. The result is concordant with the clinical and EEG findings. It can detect and localize the structural abnormality accurately and is useful in the treatment planning.

Characterize the social profile and the need of information from patients with refractory epilepsy. A semi-structured questionnaire was applied to 103 patients to investigate sociodemographic aspects, pharmacotherapy and any doubts about epilepsy. Patients were highly dependent on having a free and accessible supply of antiepileptic drugs. Sixty-eight percent of the population was unemployed, and 26% confirmed receiving social security benefits due to epilepsy. Twenty-nine percent of the population reached high school. Eighty-five percent of the patients had at least one doubt about epilepsy; treatment and epilepsy aspects in general were the main topics. As observed in developed countries, patients with refractory epilepsy from a developing country also have high rates of unemployment and low educational levels. The results raise a concern about the need of information about epilepsy by patients and their families, urging the necessity to invest in strategies to solve this deficiency in knowledge.

Epilepsy is a neurological condition that is particularly common in people with intellectual disability (ID). The care for people with both epilepsy and ID is often complicated by the presence of neuropsychiatric disorders, defined as psychiatric symptoms, psychiatric disorders, and behavioral problems. The aim of this study was to investigate associations between epilepsy or epilepsy-related factors and neuropsychiatric comorbidities in patients with ID and between ID and neuropsychiatric comorbidities in patients with epilepsy. We performed a systematic review of the literature, published between January 1995 and January 2015 and retrieved from PubMed/Medline, PsycINFO, and ERIC and assessed the risk of bias using the SIGN-50 methodology. Forty-two studies were identified, fifteen of which were assessed as having a low or acceptable risk-of-bias evaluation. Neuropsychiatric comorbidities were examined in relation to epilepsy in nine studies; in relation to epilepsy-related factors, such as seizure activity, seizure type, and medication in four studies; and in relation to the presence and degree of ID in five studies. We conclude that the presence of epilepsy only was not a clear determinant of neuropsychiatric comorbidity in patients with ID, although a tendency towards negative mood symptoms was identified. Epilepsy-related factors indicating a more severe form of epilepsy were associated with neuropsychiatric comorbidity as was the presence of ID as compared to those without ID in patients with epilepsy, although this should be validated in future research. A large proportion of the studies in this area is associated with a substantial risk of bias. There is a need for high quality studies using standardized methods to enable clear conclusions to be drawn that might assist in improving the quality of care for this population.

Management of epilepsy in patients with Rett syndrome: perspectives and considerations.

PubMed

Krajnc, Natalija

2015-01-01

Rett syndrome (RTT) is a common neurodevelopmental disorder that appears in infancy with regression of acquired motor skills, loss of purposeful activity, hand stereotypies, loss of acquired spoken language, and seizures. Epilepsy affects the majority of patients in a specific clinical stage of the disease and is drug resistant in approximately one-third of cases. The association of epilepsy and even drug-resistant epilepsy has been reported in certain genotypes of the methyl-CpG-binding protein 2 mutation, which is present in a majority of patients with classical RTT. The evolution of electroencephalographic abnormalities accompanying the clinical development of the syndrome is well described, but much less is known about the seizure semiology and the effectiveness of specific antiepileptic drugs. The aim of this review is to present the clinical and electrophysiological aspects of epilepsy in RTT and the current treatment approach.

One-third of patients with epilepsy are resistant to anti-epileptic drugs (AEDs). Drug-resistant epilepsy is believed to be multifactorial involving both genetic and non-genetic factors. Genetic variations in the ABCB1 gene encoding the drug efflux transporter, p-glycoprotein (p-gp), may influence the interindividual variability in AED response by limiting drugs from reaching their target. Phenobarbital (PB), one of the most cost-effective and widely used AEDs in developing countries, has been reported to be transported by p-gp. This study aimed to investigate the association of a genetic variant, ABCB1 3435C>T, and non-genetic factors with phenobarbital response in Thai patients with epilepsy. One hundred and ten Thai patients with epilepsy who were treated with PB maintenance doses were enrolled in this study. Two phenotypic groups, PB-responsive epilepsy and PB-resistant epilepsy, were defined according to the International League Against Epilepsy (ILAE) criteria. Subjects were genotyped for ABCB1 3435C>T (rs1045642). Multiple logistic regression analysis was tested for the association of ABCB1 3435C>T polymorphism and non-genetic factors with PB response. Sixty-two PB-responsive epilepsy subjects and 48 PB-resistant epilepsy subjects were identified. All genotype frequencies of the ABCB1 3435C>T SNP were consistent with the Hardy-Weinberg equilibrium (P > 0·05). The ABCB1 3435C>T polymorphism and type of epilepsy were associated with response to PB. Patients with PB-resistant epilepsy had a significantly higher frequency of ABCB1 3435CC genotype and had focal epilepsy more often than patients with PB-responsive epilepsy (adjusted OR = 3·962, 95% CI = 1·075-14·610, P-value = 0·039; adjusted OR = 5·936, 95% CI = 2·272-15·513, P-value < 0·001, respectively). The model explained 25·5% of the variability in response to PB (R(2)  = 0·255). Thai patients of ABCB1 3435CC genotype and with focal epilepsy were more often PB resistant. Those two

Epilepsy is a disease of recurrent seizures that can be associated with a wide variety of acquired and developmental brain lesions. Current medications for patients with epilepsy can suppress seizures; they do not cure or modify the underlying disease process. On the other hand, surgical removal of focal brain regions that produce seizures can be curative. This surgical procedure can be more precise with the placement of intracranial recording electrodes to identify brain regions that generate seizure activity as well as those that are critical for normal brain function. The detail that goes into these surgeries includes extensive neuroimaging, electrophysiology, and clinical data. Combined with precisely localized tissues removed, these data provide an unparalleled opportunity to learn about the interrelationships of many "systems" in the human brain not possible in just about any other human brain disorder. Herein, we describe a systems biology approach developed to study patients who undergo brain surgery for epilepsy and how we have begun to apply these methods to patients whose seizures are associated with brain tumors. A central goal of this clinical and translational research program is to improve our understanding of epilepsy and brain tumors and to improve diagnosis and treatment outcomes of both.

Lacosamide in refractory mixed pediatric epilepsy: a prospective add-on study.

PubMed

Rastogi, Reena Gogia; Ng, Yu-Tze

2012-04-01

Lacosamide is a new antiepileptic drug that is currently approved by the US Food and Drug Administration (FDA) for adults 17 years or older for partial-onset seizures. The authors reviewed 21 pediatric patients (<17 years) with various seizure types who were started on oral lacosamide as part of a prospective add-on study as adjunctive therapy for refractory epilepsy. Five patients were excluded due to less than 3 months of meaningful follow-up. Maintenance dosages used ranged from 2.4 to 19.4 mg/kg/d. Eight of 16 (50%) patients had greater than 50% reduction in seizure frequency with adjunctive lacosamide therapy. Eight (50%) patients had generalized epilepsy including 4 with Lennox-Gastaut syndrome. Lacosamide was effective therapy for most seizure types but was particularly effective for partial-onset seizures. Lacosamide was effective in treating 5 of 8 (62.5%) localization-related epilepsies but only 2 of 8 (25%) generalized epilepsies, both Lennox-Gastaut syndrome patients with greater than 90% seizure reduction. None of these very refractory patients remained seizure free.

Peri-ictal water drinking (PIWD) has been reported as the action of drinking during or within two minutes of an electroclinical seizure. It is considered a peri-ictal vegetative symptom, evident both during childhood and adulthood epilepsy. The aim of this paper was to describe the clinical and electroencephalographic features of two new adult subjects suffering from symptomatic temporal lobe epilepsy with episodes of PIWD recorded by VIDEO-EEG and to review literature data in order to better define this peculiar event during seizures, a rare and probably underestimated semiological sign. To date, 51 cases with focal epilepsy and seizures associated with PIWD have been reported. All patients presented with temporal lobe epilepsy. All cases but one had symptomatic epilepsy. Most of the patients had an involvement of the right hemisphere. Water drinking was reported as an ictal sign in the majority of patients, and less frequently was reported as postictal. We believe that PIWD might be considered a rare automatic behaviour, like other automatisms. Automatisms are more frequently described in patients with temporal lobe epilepsy. PIWD was reported also to have lateralizing significance in the non-dominant temporal lobe, however, because of its rarity, this finding remains unclear.

Prolonged sleep deprivation activates epileptiform EEG abnormalities and seizures in people with epilepsy. Few studies have addressed the effect of chronic partial sleep deprivation on seizure occurrence in populations with epilepsy. We tested the primary hypothesis that partial sleep deprivation over 24- and 72-hour periods increases seizure occurrence in adults with epilepsy. Forty-four subjects completed a series of self-reported instruments, as well as 1-month sleep and seizure diaries, to characterize their sleep and quality of life. Diaries were used to determine the relationship between seizure occurrence and total sleep time 24 and 72h before seizure occurrence using random effects models and a logistic regression model fit by generalized estimating equations. A total of 237 seizures were recorded during 1295 diary days, representing 5.5±7.0 (mean±SD) seizures per month. Random effects models for 24- and 72-hour total sleep times showed no clinically or statistically significant differences in the total sleep time between preseizure periods and seizure-free periods. The average 24-hour total sleep time during preseizure 24-hour periods was 8min shorter than that during seizure-free periods (p=0.51). The average 72-hour total sleep time during preseizure periods was 20min longer than that during seizure-free periods (p=0.86). The presence of triggers was a significant predictor of seizure occurrence, with stress/anxiety noted most often as a trigger. Mean total sleep time was 9h, and subjects took an average of 12±10 naps per month, having a mean duration of 1.9±1.2h. Daytime sleepiness, fatigue, and insomnia symptoms were commonly reported. Small degrees of sleep loss were not associated with seizure occurrence in our sample of adults with epilepsy. Our results also include valuable observations of the altered sleep times and frequent napping habits of adults with refractory epilepsy and the potential contribution of these habits to quality of life and

Neuroimaging correlates of language network impairment and reorganization in temporal lobe epilepsy

Advanced, noninvasive imaging has revolutionized our understanding of language networks in the brain and is reshaping our approach to the presurgical evaluation of patients with epilepsy. Functional magnetic resonance imaging (fMRI) has had the greatest impact, unveiling the complexity of language organization and reorganization in patients with epilepsy both pre- and postoperatively, while volumetric MRI and diffusion tensor imaging have led to a greater appreciation of structural and microstructural correlates of language dysfunction in different epilepsy syndromes. In this article, we review recent literature describing how unimodal and multimodal imaging has advanced our knowledge of language networks and their plasticity in epilepsy, with a focus on the most frequently studied epilepsy syndrome in adults, temporal lobe epilepsy (TLE). We also describe how new analytic techniques (i.e., graph theory) are leading to a refined characterization of abnormal brain connectivity, and how subject-specific imaging profiles combined with clinical data may enhance the prediction of both seizure and language outcomes following surgical interventions.

Effective communication between patients and their health care providers is recognized as critically important to improve the quality of health services for individuals with epilepsy. We aimed to describe in-office neurologist-patient conversations about epilepsy and focus on disease identification, shared decision-making, and care planning. Transcripts and audio recordings of conversations between patients and neurologists in the United States, Spain, and Germany were analyzed linguistically in the topic areas of epilepsy identification and diagnosis, disease education, treatments, and care planning. Analyses included word-level assessments, topic switching, strategies of information elicitation, identification of topics discussed, quantification of questions asked, and assessment of types of questions asked. Conversations of 17 neurologists in the United States, 12 in Spain, and 6 in Germany, with 50, 20, and 16 patients, respectively, were analyzed. Neurologists tended to utilize an event-based, patient-friendly vocabulary to refer to seizures, and in the United States, they avoided using the term "epilepsy." Regardless of who initiated the treatment discussion, the neurologists in all 3 countries were unilaterally responsible for the treatment decision and choice of medication. When describing a new medication, neurologists most often discussed potential side effects but did not review potential benefits. Neurologists rarely defined seizure control and did not ask patients what seizure control meant to them. We identified opportunities related to vocabulary, decision-making, and treatment goal setting that could be targeted to improve neurologist-patient communication about epilepsy, and ultimately, the overall treatment experience and outcomes for patients.

The purpose of this study was to define the influence of fatigue, depression, and clinical, demographic, and socioeconomic factors on the quality of life of patients with epilepsy. The study was performed on 103 adult patients who visited Erciyes University Epilepsy Outpatient Clinic between 2004 and 2005. Patients were evaluated with the Form of Negotiation, Quality of Life in Epilepsy Inventory (QOLIE-89), Beck Depression Inventory, and Fatigue Severity Scale. Mean age of the patients was 34.3+/-12.6, and mean duration of disease was 12.6+/-9.3 years. Among these patients, 52.4% were men, 49.5% were married, 15.5% had a university education, 53.4% had low incomes, 45.6% had generalized seizures, and 35.0% had experienced one or more seizures per month during the preceding year. The most significant variables in the domain of Overall quality of life were seizure frequency (P<0.001), depression (P<0.001), and fatigue (P<0.001); the variables in the domain of Mental Health were seizure frequency (P<0.001) and fatigue (P<0.001); the variable in the Cognitive domain was fatigue (P<0.001); the variables in the domain of Physical Health were social insurance coverage (P<0.01), fatigue (P<0.01), and age (P<0.01); the variables in the Epilepsy Targeted domain were depression (P<0.001), seizure frequency (P<0.001), and fatigue (P<0.01). Although quality of life has multiple determinants, seizure frequency, fatigue, and depression are the most important factors affecting quality of life in patients with epilepsy. One or more seizures per month, severe fatigue, and depression are associated with lower quality of life in some but not all domains. Partial correlations demonstrated that fatigue was a significant independent predictor of quality of life. The present study confirms that fatigue can be a powerful predictor of quality of life.

To study possible detection of structural abnormalities on 7T MRI that were not detected on 3T MRI and estimate the added value of MEG-guidance. For abnormalities found, analysis of convergence between clinical, MEG and 7T MRI localization of suspected epileptogenic foci. In adult patients with well-documented localization-related epilepsy in whom a previous 3T MRI did not demonstrate an epileptogenic lesion but MEG indicated a plausible epileptogenic focus, 7T MRI was performed. Based on semiologic data, visual analysis of the 7T images was performed as well as based on prior MEG results. Correlation with other data from the patient charts, for as far as these were available, was analysed. To establish the level of concordance between the three observers the generalized or Fleiss kappa was calculated. In 3/19 patients abnormalities that, based on semiology, could plausibly represent an epileptogenic lesion were detected using 7T MRI. In an additional 3/19 an abnormality was detected after MEG-guidance. However, in these later cases there was no concordance among the three observers with regard to the presence of a structural abnormality. In one of these three cases intracranial recording was performed, proving the possible abnormality on 7T MRI to be the epileptogenic focus. In 32% of patients 7T MRI showed abnormalities that could indicate an epileptogenic lesion whereas previous 3T MRI did not, especially when visual inspection was guided by the presence of focal interictal MEG abnormalities.

Genetic heterogeneity of common genetic generalized epilepsy syndromes is frequently considered. The present study conducted a focused analysis of potential candidate or susceptibility genes for common genetic generalized epilepsy syndromes using multi-gene panel testing with next-generation sequencing. This study included patients with juvenile myoclonic epilepsy, juvenile absence epilepsy, and epilepsy with generalized tonic-clonic seizures alone. We identified pathogenic variants according to the American College of Medical Genetics and Genomics guidelines and identified susceptibility variants using case-control association analyses and family analyses for familial cases. A total of 57 patients were enrolled, including 51 sporadic cases and 6 familial cases. Twenty-two pathogenic and likely pathogenic variants of 16 different genes were identified. CACNA1H was the most frequently observed single gene. Variants of voltage-gated Ca2+ channel genes, including CACNA1A, CACNA1G, and CACNA1H were observed in 32% of variants (n = 7/22). Analyses to identify susceptibility variants using case-control association analysis indicated that KCNMA1 c.400G>C was associated with common genetic generalized epilepsy syndromes. Only 1 family (family A) exhibited a candidate pathogenic variant p.(Arg788His) on CACNA1H, as determined via family analyses. This study identified candidate genetic variants in about a quarter of patients (n = 16/57) and an average of 2.8 variants was identified in each patient. The results reinforced the polygenic disorder with very high locus and allelic heterogeneity of common GGE syndromes. Further, voltage-gated Ca2+ channels are suggested as important contributors to common genetic generalized epilepsy syndromes. This study extends our comprehensive understanding of common genetic generalized epilepsy syndromes.

To describe the epidemiology of somatic and psychiatric conditions in adults with epilepsy in the community and compare it to that of people without epilepsy. A cross-sectional population-based study extracting data from the UK General Practice Research Database for the period 1995-1998. Age- and sex-standardized prevalence rates were estimated for selected conditions and groups of conditions (categorized by ICD-9 chapters) in adults with epilepsy registered with primary care physicians. Results were compared with those in adults without epilepsy in the cohort, and prevalence ratios were calculated according to two broad age groups (16-64 and older than 64 years). Conditions common in the general population also were common in adults with epilepsy. Psychiatric disorders occurred twice as often, and the risk of somatic disorders was increased in people with epilepsy, with the exception of musculoskeletal and connective tissue disorders in older adults. The prevalence ratio of neoplasia, excluding intracranial tumors, was not increased in epilepsy. The prevalence ratio of brain tumors was particularly increased in young adults [prevalence ratio (PR), 70.7] and of meningiomas in older adults (PR, 91.9). Neurodegenerative conditions, particularly dementias and Alzheimer' disease (PR, 6.3 and 8, respectively) and Parkinson' disease (PR, 3.2), appeared more frequently in people with epilepsy. Upper gastrointestinal bleed occurred more frequently in epilepsy (PR, 4.3), as did cardio- and cerebrovascular disorders, fractures, pneumonia and chronic lung diseases, and diabetes. Eczema, osteoarthritis, and rheumatoid arthritis did not occur more frequently in epilepsy. The prevalence ratio of many common psychiatric and somatic conditions is increased in adults with epilepsy who consult a primary care physician in the U.K. These findings may have implications in the diagnosis and management of epilepsy and coexisting conditions, as well as in health care provision.

One risk associated with epilepsy surgery is memory loss, but perhaps more important is how patients perceive changes in their memories. This longitudinal study evaluated changes in memory self-reports and investigated how self-reports relate to changes on objective memory measures in temporal or extratemporal epilepsy patients who underwent surgery. Objective memory (Wechsler Memory Scale-Revised) and subjective memory self-reports (Memory Assessment Clinics Self-Rating Scale) were individually assessed for 136 patients approximately 6 months before and 6 months after surgery. A measure of depressive affect (Beck Depression Inventory-2nd Edition) was used to control variance attributable to emotional distress. Despite a lack of significant correlational relationships between objective and subjective memory for the entire sample, significant correlations between objective memory scores and self-reports did emerge for a subset of patients who evidenced memory decline. Differences also were found in the subjective memory ratings of temporal lobe versus extratemporal patients. Temporal lobe patients rated their memories more negatively than did extratemporal patients and were more likely to report significant improvements in their memory after surgery. In general, patients were not accurate when rating their memories compared to other adults. However, patients with significant declines in their memories were sensitive to actual changes in their memories over time relative to their own personal baselines.

The characteristics of some population groups (patients with comorbidities, women of childbearing age, the elderly) may limit epilepsy management. Antiepileptic treatment in these patients may require adjustments. We searched articles in Pubmed, clinical practice guidelines for epilepsy, and recommendations by the most relevant medical societies regarding epilepsy in special situations (patients with comorbidities, women of childbearing age, the elderly). Evidence and recommendations are classified according to the prognostic criteria of Oxford Centre of Evidence-Based Medicine (2001) and the European Federation of Neurological Societies (2004) for therapeutic interventions. Epilepsy treatment in special cases of comorbidities must be selected properly to improve efficacy with the fewest side effects. Adjusting antiepileptic medication and/or hormone therapy is necessary for proper seizure management in catamenial epilepsy. Exposure to antiepileptic drugs (AED) during pregnancy increases the risk of birth defects and may affect fetal growth and/or cognitive development. Postpartum breastfeeding is recommended, with monitoring for adverse effects if sedative AEDs are used. Finally, the elderly are prone to epilepsy, and diagnostic and treatment characteristics in this group differ from those of other age groups. Although therapeutic limitations may be more frequent in older patients due to comorbidities, they usually respond better to lower doses of AEDs than do other age groups.

Vagal nerve stimulation (VNS) is an effective treatment for drug-resistant epilepsy that is not suitable for resective surgery, both in adults and in children. Few reports describe the adverse effects and complications of VNS. The aim of our study was to present a series of 33 pediatric patients who underwent VNS for drug-resistant epilepsy and to discuss the adverse effects and complications through a review of the literature.The adverse effects of VNS are usually transient and are dependent on stimulation of the vagus and its efferent fibers; surgical complications of the procedure may be challenging and patients sometimes require further surgery; generally these complications affect VNS efficacy; in addition, hardware complications also have to be taken into account.In our experience and according to the literature, adverse effects and surgical and hardware complications are uncommon and can usually be managed definitely. Careful selection of patients, particularly from a respiratory and cardiac point of view, has to be done before surgery to limit the incidence of some adverse effects.

Predictors of health-related and global quality of life among young adults with difficult-to-treat epilepsy and mild intellectual disability.

This study evaluated predictors of health-related quality of life (HRQOL) and global quality of life (QOL) among young adults with difficult-to-treat epilepsy and mild intellectual disability. One hundred and forty-two persons with epilepsy and cognitive problems were routinely screened on HRQOL, global QOL, and psychological distress four weeks after admission to a time-limited residential rehabilitation unit. The PESOS scales (PE = PErformance, SO = SOciodemographic aspects, S = Subjective evaluation/estimation) on epilepsy-specific problems were administered as measures of HRQOL; a questionnaire on life satisfaction and an item on overall QOL were used as measures of global QOL. Psychological distress was captured with the Symptom Checklist 90-R. Further data were gained from medical files. Quality-of- life predictors were identified using univariate methods and stepwise regression analyses. Psychological distress was the only predictor of all HRQOL and global QOL parameters. Seizure frequency was a predictor of most HRQOL variables. Other epilepsy variables affected only some HRQOL variables but were not associated with global QOL. Health-related quality of life did not seem to be strongly impaired. Only low correlations were found between HRQOL and global QOL. The notion of psychological distress as the most influential predictor of all QOL measures is in line with most findings on QOL in epilepsy. Former observations of weak associations between HRQOL and global QOL among patients with epilepsy and mild intellectual disability are supported. Thus, interventions to reduce psychological distress, besides epilepsy treatment, seem to be of great importance to improve QOL. Copyright © 2012 Elsevier Inc. All rights reserved.

OBJECTIVE: To evaluate the evidence since the 1999 assessment regarding efficacy and safety of vagus nerve stimulation (VNS) for epilepsy, currently approved as adjunctive therapy for partial-onset seizures in patients >12 years. METHODS: We reviewed the literature and identified relevant published studies. We classified these studies according to the American Academy of Neurology evidence-based methodology. RESULTS: VNS is associated with a >50% seizure reduction in 55% (95% confidence interval [CI] 50%–59%) of 470 children with partial or generalized epilepsy (13 Class III studies). VNS is associated with a >50% seizure reduction in 55% (95% CI 46%–64%) of 113 patients with Lennox-Gastaut syndrome (LGS) (4 Class III studies). VNS is associated with an increase in ≥50% seizure frequency reduction rates of ~7% from 1 to 5 years postim-plantation (2 Class III studies). VNS is associated with a significant improvement in standard mood scales in 31 adults with epilepsy (2 Class III studies). Infection risk at the VNS implantation site in children is increased relative to that in adults (odds ratio 3.4, 95% CI 1.0–11.2). VNS is possibly effective for seizures (both partial and generalized) in children, for LGS-associated seizures, and for mood problems in adults with epilepsy. VNS may have improved efficacy over time. RECOMMENDATIONS: VNS may be considered for seizures in children, for LGS-associated seizures, and for improving mood in adults with epilepsy (Level C). VNS may be considered to have improved efficacy over time (Level C). Children should be carefully monitored for site infection after VNS implantation. Neurology® 2013;81:1–7 PMID:24348133

Hypermotor seizures are most often reported from the frontal lobe but may also have temporal, parietal, or insular origin. We noted a higher proportion of patients with temporal lobe epilepsy in our surgical cohort who had hypermotor seizures. We evaluated the anatomic localization and surgical outcome in patient with refractory hypermotor seizures who had epilepsy surgery in our center. We identified twenty three patients with refractory hypermotor seizures from our epilepsy surgery database. We analyzed demographics, presurgical evaluation including semiology, MRI, PET scan, interictal/ictal scalp video-EEG, intracranial recording, and surgical outcomes. We evaluated preoperative variables as predictors of outcome. Most patients (65%) had normal brain MRI. Intracranial EEG was required in 20 patients (86.9%). Based on the presurgical evaluation, the resection was anterior temporal in fourteen patients, orbitofrontal in four patients, cingulate in four patients, and temporoparietal in one patient. The median duration of follow-up after surgery was 76.4months. Fourteen patients (60%) had been seizure free at the last follow up while 3 patients had rare disabling seizures. Hypermotor seizures often originated from the temporal lobe in this series of patients who had epilepsy surgery. This large proportion of temporal lobe epilepsy may be the result of a selection bias, due to easier localization and expected better outcome in temporal lobe epilepsy. With extensive presurgical evaluation, including intracranial EEG when needed, seizure freedom can be expected in the majority of patients. Copyright © 2016. Published by Elsevier Inc.

Pediatricians generally need to treat adult patients who require long-term care for pediatric diseases. However, little is known about the characteristics of adult patients in pediatric wards. Using a national inpatient database, the aim of this study was to determine the clinical details of adult patients admitted to pediatric wards in Japanese acute-care hospitals. We extracted all inpatients aged ≥19 years who were admitted to pediatric departments in Japan from April 2012 to March 2013. We examined the patients' main diagnoses and the use of life-supporting home medical devices. Of 417,352 patients admitted to pediatric wards during the study period, we identified 4,729 (1.1%) adult patients. The major diagnoses of the adult patients were malignancy, congenital heart disease, epilepsy, and cerebral palsy. More than 35% of the patients with cerebral palsy had a tracheostomy tube, gastrostomy tube, home central venous alimentation, or home respirator. More than 20% of patients aged ≥40 years in pediatric wards had adult diseases, including ischemic heart diseases, cerebrovascular diseases, and adult malignancy. Many adult patients in pediatric wards had adult diseases. It is essential to establish a disease-oriented support system for adults with chronic conditions that originated in their childhood.

Sudden unexpected death in epilepsy (SUDEP) is a major cause of mortality in young patients with epilepsy (PWE). Although its mechanisms are still poorly understood, they may include cardiorespiratory dysfunction. Standard 12-lead electrocardiograms (ECGs) were obtained from 62 consecutive patients (aged 18-66y) with a definite diagnosis of epilepsy, without seizures at the day of ECG, and 57 healthy controls matched for sex, age and body mass index (BMI). All ECGs were evaluated by a blinded board-certified cardiologist. Patients with symptomatic focal epilepsy represented 90.3% (N=56), of whom 56.4% (N=35) had temporal lobe epilepsy, with a mean duration of 22.02±14.96years of epilepsy. We observed more prolonged P-wave (p<0.0001) and PR interval (p=0.01) in patients than in controls. Additionally, longer QT intervals (p<0.01), pathologic QT dispersion (p<0.01) and left atrial overload (p<0.01) were more common in PWE. Multiple linear regression analysis evidenced age, gender and polytherapy as factors associated with altered ECG. Therefore, routine ECG should be requested in PWE, especially for males, increasing age and in polytherapy. Findings such as longer PR and QT interval, and pathologic QT dispersion, may reflect cardiac structural changes and/or autonomic nervous system dysfunction and indicate a risk for SUDEP.

Epilepsy is one of the most common neurological disorders. Global neurological knowledge is essential for differential diagnosis of epileptic syndromes due to the diversity of ictal semiology, causes and syndromes. Neurologists play an important role in planning the medical care for patients with epilepsy, as medication is the most fundamental therapeutic strategy. Some patients with early-onset epilepsy require joint care by pediatric neurologists, those with intractable epilepsy by neurosurgeons, and those with psychological comorbidity by psychiatrists, and neurologists should play a coordinating role. While there is a great need for neurologists to participate in epilepsy care, neurologists in Japan currently do not participate substantially in the epilepsy management system. It is necessary to train more neurologists who can provide epilepsy care and conduct basic and clinical research on epilepsy by providing continuous education on epilepsy for general neurologists as well as pre- and post-graduate medical students. Most of the patients who require long-term treatment experience many medical problems and social handicaps, such as adverse effects of medication, social stigma, educational disadvantages and difficulties in obtaining driver's license. To improve the quality of life of patients with epilepsy, it is desirable to build broad medical-social networks participated by patients, doctors, neurological nurses, psychologists, social workers, school teachers, managers of employment support facilities and care givers.

Carvalho, Benilton S.; Bilevicius, Elizabeth; Alvim, Marina K. M.; Lopes-Cendes, Iscia

2017-01-01

Mesial temporal lobe epilepsy is the most common form of adult epilepsy in surgical series. Currently, the only characteristic used to predict poor response to clinical treatment in this syndrome is the presence of hippocampal sclerosis. Single nucleotide polymorphisms (SNPs) located in genes encoding drug transporter and metabolism proteins could influence response to therapy. Therefore, we aimed to evaluate whether combining information from clinical variables as well as SNPs in candidate genes could improve the accuracy of predicting response to drug therapy in patients with mesial temporal lobe epilepsy. For this, we divided 237 patients into two groups: 75 responsive and 162 refractory to antiepileptic drug therapy. We genotyped 119 SNPs in ABCB1, ABCC2, CYP1A1, CYP1A2, CYP1B1, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4, and CYP3A5 genes. We used 98 additional SNPs to evaluate population stratification. We assessed a first scenario using only clinical variables and a second one including SNP information. The random forests algorithm combined with leave-one-out cross-validation was used to identify the best predictive model in each scenario and compared their accuracies using the area under the curve statistic. Additionally, we built a variable importance plot to present the set of most relevant predictors on the best model. The selected best model included the presence of hippocampal sclerosis and 56 SNPs. Furthermore, including SNPs in the model improved accuracy from 0.4568 to 0.8177. Our findings suggest that adding genetic information provided by SNPs, located on drug transport and metabolism genes, can improve the accuracy for predicting which patients with mesial temporal lobe epilepsy are likely to be refractory to drug treatment, making it possible to identify patients who may benefit from epilepsy surgery sooner.

2017-01-01

Background Many studies have reported an association between epilepsy, nodding syndrome (NS), and onchocerciasis (river blindness). A high prevalence of epilepsy has been noted particularly in onchocerciasis hyperendemic areas where onchocerciasis is not or insufficiently controlled with mass ivermectin distribution. There is evidence that increasing the coverage of ivermectin reduces the incidence of epilepsy, and anecdotal evidence suggests a reduction in seizure frequency in onchocerciasis-associated epilepsy (OAE) patients who receive ivermectin. Finding an alternative treatment for epilepsy in these patients will have major consequences. Objective The goal of the study is to assess whether ivermectin treatment decreases the frequency of seizures and leads to seizure freedom in OAE patients, including patients with NS. If we are able to demonstrate such an effect, this would strengthen the argument that onchocerciasis is causing epilepsy and therefore we should increase our efforts to eliminate onchocerciasis. Methods We will conduct a randomized clinical trial in the Democratic Republic of Congo to compare seizure freedom in onchocerciasis-infested epilepsy patients who receive immediate ivermectin treatment with delayed (after 4 months) ivermectin treatment. All participants will simultaneously receive antiepilepsy drugs (AEDs) according to local guidelines for epilepsy treatment. The primary endpoint is seizure freedom defined as no seizures during the 4 month of follow-up. Secondary endpoint is significant (>50%) seizure reduction compared to baseline seizure frequency. Reduction of seizures will be compared between ivermectin and nonivermectin arms. Results Start of enrollment is planned for August 2017, and we expect to have enrolled all 110 participants by December 2017. Results are expected in June 2018. Conclusions If ivermectin treatment in addition to AEDs is able to lead to seizure freedom or significantly reduces seizure frequency in OAE patients

Objective: We describe 2 additional patients with early-onset epilepsy with a de novo FGF12 mutation. Methods: Whole-exome sequencing was performed in 2 unrelated patients with early-onset epilepsy and their unaffected parents. Genetic variants were assessed by comparative trio analysis. Clinical evolution, EEG, and neuroimaging are described. The phenotype and response to treatment was reviewed and compared to affected siblings in the original report. Results: We identified the same FGF12 de novo mutation reported previously (c.G155A, p.R52H) in 2 additional patients with early-onset epilepsy. Similar to the original brothers described, both presented with tonic seizures in the first month of life. In the first patient, seizures responded to sodium channel blockers and her development was normal at 11 months. Patient 2 is a 15-year-old girl with treatment-resistant focal epilepsy, moderate intellectual disability, and autism. Carbamazepine (sodium channel blocker) was tried later in her course but not continued due to an allergic reaction. Conclusions: The identification of a recurrent de novo mutation in 2 additional unrelated probands with early-onset epilepsy supports the role of FGF12 p.R52H in disease pathogenesis. Affected carriers presented with similar early clinical phenotypes; however, this report expands the phenotype associated with this mutation which contrasts with the progressive course and early mortality of the siblings in the original report.

To evaluate the social, educational, and vocational outcomes of young adults who underwent resective epilepsy surgery in childhood (4-11 years earlier), and in a comparison group of nonsurgical patients with intractable epilepsy. Participants were 78 patients (mean age 22.37, standard deviation [SD] 2.47 years) with childhood onset intractable epilepsy, of whom 51 underwent surgery. At follow-up, participants were at least 18 years of age. Patients' current education, employment, income, and various social factors, including living arrangements, relationship status, and involvement with friends and community organizations were recorded. In addition, parents of patients completed the Adult Behaviour Checklist (ABCL). Employment status, education, and income were compared with provincial census data. There was no statistically significant difference in the proportion of surgical and nonsurgical patients who were seizure-free in the 12 months preceding the study: 53% and 33%, respectively (p = 0.10). Among all patients, 60% were enrolled in, or had completed, postsecondary education and 82% were employed or a student; similar to the general population. However, compared with population data, fewer patients with epilepsy (20%) had an annual income of $10,000 or greater (p < 0.001). Compared to normative data, a greater proportion of patients scored in the abnormal range in some ABCL scales (p < 0.028). Patients with IQs > 85 had significantly better educational, vocational, and psychosocial outcomes compared to patients with IQs ≤ 85. Surgical and nonsurgical patients did not differ on any outcome variable. Compared to patients with seizures, more seizure-free patients were living independently (p = 0.03), and had a driver's licence (p < 0.001). Other outcomes were similar among patients with and without seizures. Overall, patients with intractable epilepsy in childhood attained educational and vocational outcomes similar to that of the general population, but earned

Background Temporal lobe epilepsy is the second most common neurological disorders characterized by recurrent spontaneous seizures. MicroRNAs play a vital role in regulating synaptic plasticity, brain development and post-transcriptional expression of proteins. In both animal models of epilepsy and human patients, miR-134, a brain-specific microRNA has recently been identified as a potential regulator of epileptogenesis. Methods microRNA identified as targets for the actions of valproic acid (VPA) are known to have important effects in brain function. In this study, 59 new-onset epilepsy patients and 20 controls matched by sex and age were enrolled. Patients with a score < 3 were allocated into the mild group, 3-5 into the moderate group and >5 into the severe group. The plasma miRNA-134 level was quantitatively measured using real-time PCR. Results Plasma miRNA-134 level in new-onset epilepsy patients was significantly up-regulated when compared with that in healthy controls, and then considerably down-regulated after oral intake of valproic acid medication. The up-regulated plasma miRNA-134 levels may be directly associated with the pathophysiology and severity of epilepsy. Conclusion Plasma miRNA-134 in epilepsy may be considered as a potential peripheral biomarker that responds to the incidence of epilepsy and associates with use of anti-epilepsy drugs. PMID:29069823

An 8-year-old girl treated at our facility for superrefractory status epilepticus was found to have a low pyridoxine level at 5 μg/L. After starting pyridoxine supplementation, improvement in the EEG for a 24-hour period was seen. We decided to look at the pyridoxine levels in adult patients admitted with status epilepticus. We reviewed the records on patients admitted to the neurological ICU for status epilepticus (SE). Eighty-one adult patients were identified with documented pyridoxine levels. For comparison purposes, we looked at pyridoxine levels in outpatients with epilepsy (n=132). Reported normal pyridoxine range is >10 ng/mL. All but six patients admitted for SE had low normal or undetectable pyridoxine levels. A selective pyridoxine deficiency was seen in 94% of patients with status epilepticus (compared to 39.4% in the outpatients) which leads us to believe that there is a relationship between status epilepticus and pyridoxine levels.

2014-07-01

The objective of this study was to analyze drug treatment in patients with newly diagnosed unprovoked seizures/epilepsy in a population-based cohort in Stockholm, Sweden. Clinical data from the Stockholm Incidence Registry of Epilepsy was cross-linked with drug dispensing data from the Swedish Prescribed Drug Register to analyze drug treatment in patients diagnosed with unprovoked seizures between 2006 and 2008. Specific questions addressed were the use of other medications at seizures onset, the proportion of patients initiated on different antiepileptic drugs (AEDs) within one year after inclusion, and the extent of switching between different AEDs during the first year. In total 367 patients were included. More than 50% had other medications prescribed at date of first seizure. All together, 262 patients received an AED within one year and 257 patients (98%) were initiated on monotherapy. One year after first prescription, 147 patients (56%) remained on the initially prescribed AED and 48 patients (18%) had switched to another AED. Among the remaining patients, 29 (11%) had died and 38 patients (15%) had discontinued AED treatment. A majority of all patients with epilepsy receive treatment within one year. Many patients use other medications and several of them are related to known comorbidities and can also be involved in drug-drug interactions. Nevertheless, most patients remained on the same AED at the end of the first year. Copyright © 2014 Elsevier B.V. All rights reserved.

The aims of this study were to investigate the recognition gap on the quality of life (QOL) in people with epilepsy (PWE) between the affected pediatric and adolescent patient's families and the attending physicians, and to devise future management strategies for epilepsy based on the results. We conducted a large-scale questionnaire survey on the QOL in 5,122 PWE/their families who were members of the Japanese Epilepsy Association in 2006 and 1,701 PWE/their families and 502 attending physicians responded. Out of the responders, 107 matched pairs of PWE aged under 16 years (with an adult family member actually responding by proxy) and their physicians responding to the questionnaire were examined. The results demonstrated that the physicians were not sufficiently aware of 1) concern about drug therapy for epilepsy from the perspective of their patients/families, 2) ictal and post-ictal symptoms recognized by the patients/their families, and 3) the worry about the disease of the patients/their families. Thus, efforts are needed to minimize the recognition gap within the limited consultation hour in routine clinical practice between children and adolescents having epilepsy/their families and physicians : physicians should efficiently acquire necessary information from PWE/their families, and should negotiate with PWE/their families about the goal of therapy and future management strategies for epilepsy.

The current study assessed the knowledge and attitudes of dentists and neurologists, and of their patients with epilepsy, in the catchment area of an outpatient clinic for epilepsy in southern Germany. One-hundred patients with epilepsy were asked to complete questionnaires about their dental treatment. Attitudes of their attending dentists and neurologists were also assessed. Patients with epilepsy: The questionnaires were returned by 82% of patients. Of these, 84% regularly (once or twice a year) sought out a dentist, 79% reported their epilepsy to the dentist, 6% were refused treatment by a dentist because of their epilepsy, 10% had already experienced a seizure while at a dental office and 52% wished for more detailed information pretreatment. Dentists: Although 97% treated patients with epilepsy, 21% believed that their equipment was inappropriate for treating a patient experiencing seizures. The majority were not familiar with interactions between antibiotics/analgetics and anti-epileptic drugs. Short-term general anaesthesia was preferred for critical patients by 70% of dentists, 70% recommended dental ceramic for prosthetic reconstruction of anterior teeth and 64% would not recommend use of a removable denture. Neurologists: Sixty-two per cent were asked for advice by their patients, 71% knew about particular risks and interactions between antibiotics/analgetics and anti-epileptic drugs, 8% would stop valproic acid before extensive dental intervention and 92% recommended general anaesthesia in critical patients (uncooperative patients, patients with learning difficulties, and patients with frequent generalised tonic-clonic or complex partial seizures). In general, patients were satisfied with their dental treatment. Regarding the clinician's role, however, dentists need to know more with respect to treating patients with seizures. Beyond that, it would be desirable for neurologists to take more time to answer their patients' questions regarding dental care

Importance of Video-EEG Monitoring in the Diagnosis of Epilepsy in a Psychiatric Patient

PubMed Central

Kirmani, Batool F.

2013-01-01

Epilepsy is a chronic medical condition which is disabling to both patients and caregivers. The differential diagnosis of epilepsy includes psychogenic nonepileptic spells or “pseudoseizures.” Epilepsy is due to abnormal electrical activity in the brain, and pseudoseizure is a form of conversion disorder. The brain waves remain normal in pseudoseizures. The problem arises when a patient with significant psychiatric history presents with seizures. Pseudoseizures become high on the differential diagnosis without extensive work up. This is a case of woman with significant psychiatric issues which resulted in a delay in the diagnosis of epilepsy.

2016-09-01

Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked epileptic seizures. The majority of people given a diagnosis of epilepsy have a good prognosis, but 20-30 % will develop drug-resistant epilepsy. Vagus nerve stimulation (VNS) is a neuromodulatory treatment that is used as an adjunctive therapy for treating people with medically refractory epilepsy. It consists of chronic intermittent electrical stimulation of the vagus nerve, delivered by a programmable pulse generator (Neuro-Cybernetic Prosthesis). In 1997, the Food and Drug Administration approved VNS as adjunctive treatment for medically refractory partial-onset seizures in adults and adolescents. This article reviews the literature from 1988 to nowadays. We discuss thoroughly the anatomy and physiology of vagus nerve and the potential mechanisms of actions and clinical applications involved in VNS therapy, as well as the management, safety, tolerability and effectiveness of VNS therapy. VNS for partial seizures appears to be an effective and well tolerated treatment in adult and pediatric patients. People noted improvements in feelings of well-being, alertness, memory and thinking skills, as well as mood. The adverse effect profile is substantially different from the adverse effect profile associated with antiepileptic drugs, making VNS a potential alternative for patients with difficulty tolerating antiepileptic drug adverse effects. Despite the passing years and the advent of promising neuromodulation technologies, VNS remains an efficacy treatment for people with medically refractory epilepsy. Past and ongoing investigations in other indications have provided signals of the therapeutic potential in a wide variety of conditions.

The aim of this study is to determine whether the use of 7 tesla (T) MRI in clinical practice leads to higher detection rates of focal cortical dysplasias in possible candidates for epilepsy surgery. In our center patients are referred for 7 T MRI if lesional focal epilepsy is suspected, but no abnormalities are detected at one or more previous, sufficient-quality lower-field MRI scans, acquired with a dedicated epilepsy protocol, or when concealed pathology is suspected in combination with MR-visible mesiotemporal sclerosis-dual pathology. We assessed 40 epilepsy patients who underwent 7 T MRI for presurgical evaluation and whose scans (both 7 T and lower field) were discussed during multidisciplinary epilepsy surgery meetings that included a dedicated epilepsy neuroradiologist. We compared the conclusions of the multidisciplinary visual assessments of 7 T and lower-field MRI scans. In our series of 40 patients, multidisciplinary evaluation of 7 T MRI identified additional lesions not seen on lower-field MRI in 9 patients (23%). These findings were guiding in surgical planning. So far, 6 patients underwent surgery, with histological confirmation of focal cortical dysplasia or mild malformation of cortical development. Seven T MRI improves detection of subtle focal cortical dysplasia and mild malformations of cortical development in patients with intractable epilepsy and may therefore contribute to identification of surgical candidates and complete resection of the epileptogenic lesion, and thus to postoperative seizure freedom.

Determining Surgical Candidacy in Temporal Lobe Epilepsy

Temporal lobe epilepsy (TLE) is the most common form of adult epilepsy that is amenable to surgical treatment. In the carefully selected patient, excellent seizure outcome can be achieved with minimal or no side effects from surgery. This may result in improved psychosocial functioning, achieving higher education, and maintaining or gaining employment. The objective of this paper is to discuss the surgical selection process of a patient with TLE. We define what constitutes a patient that has medically refractory TLE, describe the typical history and physical examination, and distinguish between mesial TLE and neocortical TLE. We then review the role of routine (ambulatory/sleep-deprived electroencephalography (EEG), video EEG, magnetic resonance imaging (MRI), neuropsychological testing, and Wada testing) and ancillary preoperative testing (positron emission tomography, single-photon emission computed tomography (SPECT), subtraction ictal SPECT correlated to MRI (SISCOM), magnetoencephalography, magnetic resonance spectroscopy, and functional MRI) in selecting surgical candidates. We describe the surgical options for resective epilepsy surgery in TLE and its commonly associated risks while highlighting some of the controversies. Lastly, we present teaching cases to illustrate the presurgical workup of patients with medically refractory TLE. PMID:22957238

New antiepileptic drugs in pediatric epilepsy.

PubMed

Hwang, Hee; Kim, Ki Joong

2008-10-01

New antiepileptic drugs (AEDs), introduced since 1993, provide more diverse options in the treatment of epilepsy. Despite the equivalent efficacy and better tolerability of these drugs, more than 25% of patients remain refractory to treatment. Moreover, the issues for pediatric patients are different from those for adults, and have not been addressed in the development and application of the new AEDs. Recently published evidence-based treatment guidelines have helped physicians to choose the most reasonable AED, although they cannot fully endorse new AEDs because of the lack of well-designed, randomized controlled trials. We review the mechanisms of action, pharmacokinetic properties, adverse reactions, efficacy, and tolerability of eight new AEDs (felbamate, gabapentin, lamotrigine, levetiracetam, oxcarbazepine, topiramate, vigabatrin, and zonisamide), focusing on currently available treatment guidelines and expert opinions regarding pediatric epilepsy.

Depression and Genetic Causal Attribution of Epilepsy in Multiplex Epilepsy Families

Summary Objectives Rapid advances in genetic research and increased use of genetic testing have increased the emphasis on genetic causes of epilepsy in patient encounters. Research in other disorders suggests that genetic causal attributions can influence patients’ psychological responses and coping strategies, but little is currently known about how epilepsy patients and their relatives will respond to genetic attributions of epilepsy. We investigated the possibility that depression, the most frequent psychiatric comorbidity in the epilepsies, might be related to the perception that epilepsy has a genetic cause among members of families containing multiple individuals with epilepsy. Methods A self-administered survey was completed by 417 individuals in 104 families averaging four individuals with epilepsy per family. Current depression was measured with the PHQ-9. Genetic causal attribution was assessed by three questions addressing: perceived likelihood of having an epilepsy-related mutation, perceived role of genetics in causing epilepsy in the family, and (in individuals with epilepsy) perceived influence of genetics in causing the individual’s epilepsy. Relatives without epilepsy were asked about their perceived chance of developing epilepsy in the future, compared with the average person. Results Prevalence of current depression was 14.8% in 182 individuals with epilepsy, 6.5% in 184 biological relatives without epilepsy, and 3.9% in 51 married-in individuals. Among individuals with epilepsy, depression was unrelated to genetic attribution. Among biological relatives without epilepsy, however, prevalence of depression increased with increasing perceived chance of having an epilepsy-related mutation (p=0.02). This association was not mediated by perceived future epilepsy risk among relatives without epilepsy. Significance Depression is associated with perceived likelihood of carrying an epilepsy-related mutation among individuals without epilepsy in

Electroconvulsive therapy and subsequent epilepsy in patients with affective disorders: A register-based Danish cohort study.

Bøg, Fie Krossdal; Jørgensen, Martin Balslev; Andersen, Zorana Jovanovic; Osler, Merete

It has been suggested that Electroconvulsive Therapy (ECT) might increase the risk of epilepsy but the few patient studies with retrospective data from medical records do not support the hypothesis. The aim of this study was to examine the relationship between ECT and subsequent incident epilepsy in patients with affective disorder. We also explored whether any association varied with number of ECTs and time since last treatment. All 169,457 patients with first hospital contact for an affective disorder between January 2005 and December 2015 were identified in the Danish National Patient Registry and followed for incident epilepsy from January 2005 until November 2016. The association between ECT and epilepsy was examined using Cox proportional hazard regression with adjustment for gender, age, educational level, comorbid schizophrenia, previous stroke and antidepressant and antipsychotic medication use. A total of 5875 patients had at least one ECT and 1873 patients developed epilepsy (Incidence rate: 213 pr. 100,000 person years) during the follow-up of mean 5 years. In patients below age 40 years, ECT was associated with a higher rate of epilepsy after adjustment for covariables (Hazard Ratio (HR) = 1.84; 95% Confidence Intervals (CI) = [1.24-2.74]). In patients aged 41-60 years ECT was not associated with epilepsy, while for those above 60 treated with ECT the rate was lower (HR = 0.57; (95% CI = [0.37-0.89]). In patients with affective disorders, we found a weak positive association between ECT and subsequent diagnosis of epilepsy in those younger than 40 years, and a weak negative association in patients older than 60 years. The associations might be subject to residual confounding from risk factors related to ECT. Copyright © 2017 Elsevier Inc. All rights reserved.

Objectives This exploratory study identifies barriers and facilitators to self-management to inform future epilepsy self-management interventions for persons who have epilepsy complicated by co-morbid mental health conditions and serious medical events. Methods Focus group methods were used in a series of community advisory board meetings. Analysis was conducted using a thematic, constant comparative approach aiming to describe the range of barriers and facilitators salient to participants. There were a total of 22 participants, including 8 health professionals, 9 patients with epilepsy, and 5 care partners. Mean age was 49.1 (SD = 11.0, range 32-69), 11 (50%) were female, and 11 (50%) were male. For those with epilepsy, mean years having epilepsy was 24.7 (SD = 19.9, range 1-58 years). Results Individual psychological barriers (mental illness, fatigue, and psychological distress) prominently interfered with health behaviors. Community and family barriers included stigma, lack of epilepsy knowledge, and poor social support. Facilitators included planning for seizures, learning about medications, stress management, socializing with others, and talking with other epilepsy patients. Discussion Qualitative evidence in this study suggests a linkage between social integration and positive health behaviors. Future efforts to embed patients with epilepsy and their caregivers into clinical care processes could offset barriers and enhance facilitators.

Summary Objective Current medications for patients with epilepsy work in only two out of three patients. For those medications that do work, they only suppress seizures. They treat the symptoms, but do not modify the underlying disease forcing patients to take these drugs with significant side effects often for the rest of their lives. A major limitation in our ability to advance new therapeutics that permanently prevent, reduce the frequency of, or cure epilepsy comes from a lack of understanding of the disease coupled with a lack of reliable biomarkers that can predict who has or who will get epilepsy. Methods The main goal of this report is to present a number of approaches on how we may be able to identify reliable biomarkers from observing patients with brain disorders that have a high probability of producing epilepsy. Results A given biomarker, or more likely a profile of biomarkers, will have both a quantity and a time course during epileptogenesis that can be used to predict who will get the disease, to confirm epilepsy as a diagnosis, to identify co-existing pathologies, and monitor the course of treatments. Significance Additional studies in patients and animal models could identify common and clinically valuable biomarkers as a means to successfully translate animal studies into new and effective clinical trials.

While antiepileptic drugs (AEDs) provide adequate seizure control for most patients with epilepsy, ~30% continue to have seizures despite treatment with two or more AEDs.1 In addition to direct harm from seizures, poor epilepsy control correlates with higher mortality, morbidity, 2, 3 and cost to the healthcare system.4 In the subset of patients with persistent seizures despite medical management, surgical intervention and neuromodulation may be more effective. Primary care physicians and general neurologists should be aware of non-AED treatment options that are standard of care for drug- resistant epilepsy (DRE).

Epileptic seizures have been known from time immemorial. Throughout the ages, however, ideas concerning the aetiology and treatment of epilepsy have changed considerably. Epilepsy is mentioned many times in the Pentateuch, where it is portrayed as a mysterious condition, whose symptoms, course and contingencies evade rational laws and explanations. In the Middle Ages, the accepted view which prevailed in social consciousness was that patients with epilepsy were possessed by Satan and other impure spirits. One common method of treatment of epileptic seizures was to submit the patient to cruel exorcisms. Patients were frequently injured in the process and some of them even died. Our understanding of epilepsy and its social consequences has improved considerably within the last century. The most significant progress as far as diagnosis and treatment of epilepsy is concerned took place in the last four decades of the twentieth century. Although we now know much more about epilepsy than we used to, this knowledge is still insufficiently popularized.

Epilepsy affects approximately 1% of the population in the United States with frequent hospital admissions accounting for a significant burden on patients and society as a whole. Weekend admissions have generally been found to have poorer outcomes compared to weekday admissions with increased rates of preventable complications, such as nationally identified "hospital-acquired conditions" (HAC). This study aimed to assess the impact of weekend admission on HACs and mortality in the adult epilepsy population. All adult patients with epilepsy hospitalized in the U.S. from 2000 to 2010 in the Nationwide Inpatient Sample. There were 12,997,181 admissions for epilepsy with 10,106,152 (78%) weekday, 2,891,019 (22%) weekend, and 10 (<0.1%) missing admissions. Weekend admissions saw a 10% increased likelihood of both HACs (RR=1.10, 95% CI:1.09, 1.11, p<0.01) and mortality (RR=1.10, 95% CI: 1.09, 1.11, p<0.01) compared to weekday admissions. The occurrence of HAC was associated with higher inpatient charges (RR=1.36, 95% CI: 1.35, 1.36, p<0.01), pLOS (RR=1.21, 95% CI: 1.21, 1.22, p<0.01), and higher mortality (RR=1.13, 95% CI: 1.12, 1.14, p<0.01). Prior studies have shown weekend admissions are usually associated with higher rates of complications leading to higher costs and a longer hospital stay. Likewise, weekend admissions for epilepsy were associated with increased rates of HACs and mortality; however, they were also negatively associated with LOS and total charge. Thus, weekend admissions for epilepsy should be considered high risk with greater effort made to mitigate these risks. Copyright © 2017 Elsevier Inc. All rights reserved.

Reports on cases of epilepsy in Turner syndrome are rare and most of them have cortical developmental malformations. We report the case of a Taiwanese patient with mosaic Turner syndrome with generalized tonic-clonic epilepsy and asymmetrical lateral ventricles but no apparent cortical anomaly. A 49-year-old Taiwanese woman without family history presented with infrequent generalized tonic-clonic epilepsy since she was 11 years old. On examination, her short stature, webbed neck, swelling of hands and feet, retrognathic face, and mild intellectual disability were noted. She had spontaneous menarche and regular menses. Brain magnetic resonance imaging showed asymmetrical lateral ventricles and diffuse subcortical white matter T2-weighted hyperintensities. Chromosome studies disclosed low aneuploid (10%) 45,X/46,XX/47,XXX mosaic Turner syndrome. There is increasing evidence that epilepsy can be an uncommon presentation of Turner syndrome. Mosaic Turner syndrome with 47, XXX probably increases the risk of epilepsy but more research is needed to reach a conclusion. This case also strengthens our knowledge that Turner syndrome can be one of the pathologic bases of asymmetrical lateral ventricles. When a patient has idiopathic/cryptogenic epilepsy or asymmetrical lateral ventricles on brain images, the presence of a mild Turner phenotype warrants further chromosome studies.

Patients with pharmacoresistant temporal lobe epilepsy (TLE) contemplating brain surgery must make a complex treatment decision involving trade-offs. Patient decision aids, containing information on the risks and benefits of treatment interventions, increase patient knowledge and facilitate shared decision making between patients and physicians. We conducted five focus groups to describe the information patients need to make informed decisions about TLE surgery. Twenty patients who had undergone TLE surgery described the information used in their decision-making process, and evaluated the potential for a patient decision aid to assist other patients who are considering surgery. Thematic analysis revealed information needs that were both experiential (i.e., learning about other patients' experiences through testimonials) and factual (i.e., individualized statistical information). Patients also made suggestions on how this information should be delivered to patients. These data will accelerate the development of a patient decision aid designed to assist TLE patients in their decision making about epilepsy surgery. Copyright © 2011 Elsevier Inc.

Women with epilepsy (WWE) have lower birth rates than expected. The reasons for this are multifactorial and involve a complex interaction between reproductive endocrine and psychosocial factors. The effect of epilepsy surgery on reproduction in women with drug-resistant focal epilepsy has not previously been studied. Adult women of childbearing age (18-45years old) with drug-resistant focal epilepsy who had undergone a focal cortical resection between 1997 and 2008 at the Mayo Clinic in Rochester, MN were included in the study. Patients who had a history of hysterectomy or tubal ligation or who were menopausal at the time of surgery were excluded. Data on prior pregnancies and births, epilepsy history, surgical treatment, hormonal dysfunction, and socioeconomic status were obtained using a retrospective chart review. Associations between various clinical and demographic variables with changes in pregnancies and births from pre- to postsurgery were assessed using Chi-square or Fisher's exact test for categorical variables and Wilcoxon rank sum test for continuous variables. All tests were 2-sided, and p-values less than 0.05 were considered statistically significant. All analyses were performed using SAS software version 9.2 (SAS INC, Cary NC). One hundred and thirteen women (average age: 30.5years) were included in the study. Average length of follow-up was 5.7years (SD-3.90). Sixty-four patients (57.5%) were nulliparous at the time of surgery. Sixty-one patients (54%) had never been married. Average number of pregnancies per patient prior to surgery was 0.93, and average number of births prior to surgery was 0.73. After surgery, a total of 17 women had a total of 35 pregnancies and 25 births. The average number of pregnancies and births after surgery was 1.27 and 0.96, respectively. Infertility was reported in one patient postoperatively. Patients who were younger at the time of surgery experienced a greater change in the number of pregnancies and births after

Despite collection of patient reported outcome (PRO) data in clinical trials of antiepileptic drugs (AEDs), PRO results are not being routinely reported on European Medicines Agency (EMA) and Food and Drug Administration (FDA) product labels. This review aimed to evaluate epilepsy-specific PRO instruments against FDA regulatory standards for supporting label claims. Structured literature searches were conducted in Embase and Medline databases to identify epilepsy-specific PRO instruments. Only instruments that could potentially be impacted by pharmacological treatment, were completed by adults and had evidence of some validation work were selected for review. A total of 26 PROs were reviewed based on criteria developed from the FDA regulatory standards. The ability to meet these criteria was classified as either full, partial or no evidence, whereby partial reflected some evidence but not enough to comprehensively address the FDA regulatory standards. Most instruments provided partial evidence of content validity. Input from clinicians and literature was common although few involved patients in both item generation and cognitive debriefing. Construct validity was predominantly compromised by no evidence of a-priori hypotheses of expected relationships. Evidence for test-retest reliability and internal consistency was available for most PROs although few included complete results regarding all subscales and some failed to reach recommended thresholds. The ability to detect change and interpretation of change were not investigated in most instruments and no PROs had published evidence of a conceptual framework. The study concludes that none of the 26 have the full evidence required by the FDA to support a label claim, and all require further research to support their use as an endpoint. The Subjective Handicap of Epilepsy (SHE) and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) have the fewest gaps that would need to be addressed through

The aim of this study was to evaluate cognitive impairment in patients having epilepsy or psychogenic nonepileptic seizures (PNESs) using selected neuropsychological tests at different time periods related to the seizure. In this study, selected neurocognitive tests were administered to the patients. Within 24 h, the previously applied neurocognitive tests were repeated within 24 h following the observation of typical seizures when monitoring and normalizing electroencephalography (EEG) activity. Basal neurocognitive tests were also administered to the healthy control group, and repeat neurocognitive evaluation was performed within 24-96 h. The basal neurocognitive evaluation revealed that verbal learning and memory scores as well as Stroop test interference time were significantly lower in the PNES group compared with those in the controls. In the basal cognitive tests administered to the patients with epilepsy, verbal learning and memory scores, long-term memory, and total recognition test scores were significantly lower than those of the controls. Following the repeat cognitive tests, significant progress was found in the verbal categorical fluency score of the PNES group. No significant difference was determined in the epilepsy group. Significant contraction was determined in the Stroop interference time in the control group, but no similar change was recorded in the epilepsy or PNES groups. While memory problems seemed to be most prominent in the assessed patients with epilepsy, attention and executive function problems were more dominant in the patients with PNESs. These findings are probably related to numerous factors such duration of disease, mood disorders, and specific drug use. No deterioration in attention and executive functions was reported in the early post-seizure period in either patient group.

Eslicarbazepine-acetate (ESL) is a third generation antiepileptic drug licensed as adjunctive therapy in adults with focal seizures. Efficacy and safety of ESL have been established in real-life setting. However, data about outcomes in elderly patients are scarce. Primary endpoint was to evaluate outcomes of ESL in elderly patients. This was a retrospective survey that included patients >65years with focal seizures who started ESL between January 2010 and July 2012 at 12 Spanish Hospitals. ESL was prescribed individually according to real-life practice. Efficacy and safety were evaluated over 1year. These patients were included within the bigger study ESLIBASE. We included 29 patients, most of them males (18). Mean age was 71.2 year-old and epilepsy evolution was 20 years. Eighteen were pharmacorresistant at baseline. At 12 months, the mean dose was 850mg/day, the retention rate 69%, the responder rate 62% and 24.1% were seizure-free. At 12 months, 16 patients (55.2%) had ≥1 adverse effect (AE), that led to discontinuation in 7 patients. Dizziness, nausea and ataxia were the most common AEs. The tolerability profile improved in 4/5 patients who switched from carbamazepine (CBZ) or oxcarbazepine (OXC) to ESL due to AEs. ESL was well-tolerated and effective in elderly patients in a real-life setting over 1year, with a dose around 800mg/day. AE effects improved in most of who switched from CBZ or OXC to ESL.

Addressing the burden of epilepsy: Many unmet needs.

PubMed

Epilepsy is a heterogeneous clinical condition characterized by recurrent unprovoked seizures, their causes and complications. The incidence, prevalence and mortality of epilepsy vary with age, place and time contributing to a variable extent to the burden of the disease. Diagnostic misclassification may have strong impact on personal and societal reflections of the disease in light of its clinical manifestations and the need for chronic treatment. Epilepsy accounts for a significant proportion of the world's disease burden ranking fourth after tension-type headache, migraine and Alzheimer disease. Among neurological diseases, it accounts for the highest disability-adjusted life year rates both in men and in women. Although epilepsy is self-remitting in up to 50% of cases, variable long-term prognostic patterns can be identified based on the response to the available treatments. Epilepsy carries an overall increased risk of premature mortality with variable estimates across countries. Premature mortality predominates in patients aged less than 50 years, with epilepsies due to structural/metabolic conditions, with generalized tonic-clonic seizures, and seizures not remitting under treatment. Among deaths directly attributable to epilepsy or seizures, included are sudden unexpected death in epilepsy (SUDEP), status epilepticus, accidents, drowning, unintentional injuries, and suicide. Somatic and psychiatric disorders prevail in patients with epilepsy than in people without epilepsy. Asthma, migraine and cerebral tumors tend to occur more frequently in younger adults while cardiovascular disorders, stroke, dementia and meningioma predominate in the elderly. As being a fairly common clinical condition affecting all ages and requiring long-term (sometimes lifelong) treatment, epilepsy carries high health care costs for the society. Direct costs peak in the first year after diagnosis and then vary according to the severity of the disease, the response to treatment, and
