Comparison between febrile and afebrile seizures associated with mild rotavirus gastroenteritis

PurposeWe aimed on identifying the differences of febrile and afebrile seizures associated with mild rotavirus gastroenteritis (RVGE) in the pediatric population.MethodMedical charts of pediatric patients who had been admitted between July 1999 and June 2011 due to RVGE were retrospectively reviewed. Subjects were ultimately divided into three groups; ‘no seizure’ (NS: patients without seizure), ‘febrile seizure’ (FS: patients with fever during seizure), ‘afebrile seizure’ (AFS: patients without fever during seizure). Comparisons between groups were carried out on demographic and clinical characteristics, laboratory test results, electroencephalogram findings, brain magnetic resonance imaging findings, antiepileptic treatment, and prognosis.ResultsAmong the 755 subjects who had been admitted due to mild rotavirus enteritis, 696 (90.3%) did not have any seizures, 17 (2.2%) had febrile seizures, 42 (5.5%) had afebrile seizures. The duration of gastrointestinal symptoms before the onset of seizures were significantly shorter in the FS group compared to the AFS group (1.3 ± 0.8 vs. 2.8 ± 1.0 days; p < 0.0001). A single seizure attack was significantly higher in the AFS group (3.0 ± 1.6 vs. 1.7 ± 1.0 episodes; p = 0.0003), and the frequency of seizures that were of focal type with or without secondary generalization were significantly higher in the AFS group (33.3% vs. 6.0%; p = 0.0139). All patients among the FS and AFS group had not received further antiepileptic treatment after discharge, and none developed epilepsy during follow up period.ConclusionDespite some differences in seizure characteristics, both febrile and afebrile seizures associated with mild RVGE were mostly benign with a favorable prognosis.     

El insomnio y la pobre calidad de sueño se asocian a un mal control de crisis en pacientes con epilepsia

ObjectivesThis study aimed to assess the presence of sleep disorders in patients with epilepsy and to analyse their association with seizure control.MethodsWe performed a cross-sectional study of patients with epilepsy, recruited consecutively between September 2017 and December 2018. Patients were classified as having good seizure control (no seizures in the last 4 weeks) or poor seizure control (at least one seizure in the last 4 weeks). We performed intergroup comparisons for demographic and clinical data, insomnia (Insomnia Severity Index [ISI]), excessive daytime sleepiness (Epworth Sleepiness Scale [ESS]), sleep quality (Pittsburgh Sleep Quality Index [PSQI]), depression (Beck Depression Inventory-II [BDI-II]), and quality of life (Quality of Life in Epilepsy Inventory-10 [QOLIE-10]).ResultsThe sample included a total of 123 patients, of whom 31.7% had excessive daytime sleepiness (ESS ≥ 10), 50.4% had insomnia (ISI ≥ 10), and 53.6% had poor sleep quality (PSQI ≥ 5). According to our multivariate analysis, presence of seizures was associated with unemployment (odds ratio [OR] = 4.7; 95% confidence interval [CI], 1.36-19.2; P = .02), a higher number of antiepileptic drugs (OR = 5.87; 95% CI, 1.81-27.1; P < .001), insomnia (OR = 1.9; 95% CI, 1.1-9.3; P = .04), and poor sleep quality (OR = 2.8; 95% CI, 1.9-10.32; P = .01).ConclusionsSleep disorders are common in patients with epilepsy. Insomnia and poor sleep quality were associated with poor seizure control. These findings support the hypothesis that sleep disorders constitute a significant comorbidity of epilepsy, especially in patients with poor seizure control.     

Predictive factors of postoperative outcome in the elderly after resective epilepsy surgery

ObjectiveTo evaluate the efficiency of resective epilepsy surgery (RES) in patients over 50 years and determine prognostic factors.ResultsOver the 147 patients over 50 years (54.9 ± 3.8 years [50–69]) coming from 8 specialized French centres for epilepsy surgery, 72.1%, patients were seizure-free and 91.2% had a good outcome 12 months after RES. Seizure freedom was not associated with the age at surgery or duration of epilepsy. In multivariate analysis, seizure freedom was associated with MRI and neuropathological hippocampal sclerosis (HS) (P = 0.009 and P = 0.028 respectively), PET hypometabolism (P = 0.013), temporal epilepsy (P = 0.01). On the contrary, the need for intracranial exploration was associated with a poorer prognosis (P = 0.001). Postoperative number of antiepileptic drugs was significantly lower in the seizure-free group (P = 0.001). Neurological adverse event rate after surgery was 21.1% and 11.7% of patients had neuropsychological adverse effects overall transient.ConclusionsRES is effective procedure in the elderly. Even safe it remains at higher risk of complication and population should be carefully selected. Nevertheless, age should not be considered as a limiting factor, especially when good prognostic factors are identified.     

Comorbidities and risk factors associated with newly diagnosed epilepsy in the U.S. pediatric population

Neurobehavioral comorbidities can be related to underlying etiology of epilepsy, epilepsy itself, and adverse effects of antiepileptic drugs. We examined the relationship between neurobehavioral comorbidities and putative risk factors for epilepsy in children with newly diagnosed epilepsy. We conducted a retrospective analysis of children aged ≤ 18 years in 50 states and the District of Columbia, using the Truven Health MarketScan® commercial claims and encounters database from January 1, 2009 to December 31, 2013. The eligible study cohort was continuously enrolled throughout 2013 as well as enrolled for any days during a baseline period of at least the prior 2 years. Newly diagnosed cases of epilepsy were defined by International Classification of Diseases, Ninth Revision, Clinical Modification-coded diagnoses of epilepsy or recurrent seizures and evidence of prescribed antiepileptic drugs during 2013, when neither seizure codes nor seizure medication claims were recorded during baseline periods. Twelve neurobehavioral comorbidities and eleven putative risk factors for epilepsy were measured. More than 6 million children were analyzed (male, 51%; mean age, 8.8 years). A total of 7654 children were identified as having newly diagnosed epilepsy (125 per 100,000, 99% CI = 122–129). Neurobehavioral comorbidities were more prevalent in children with epilepsy than children without epilepsy (60%, 99% CI = 58.1–61.0 vs. 23%, CI = 23.1–23.2). Children with epilepsy were far more likely to have multiple comorbidities (36%, 99% CI = 34.3–37.1) than those without epilepsy (8%, 99% CI = 7.45–7.51, P < 0.001). Preexisting putative risk factors for epilepsy were detected in 28% (99% CI = 26.9–29.6) of children with epilepsy. After controlling for demographics, neurobehavioral comorbidities, family history of epilepsy, and other risk factors than primary interest, neonatal seizures had the strongest independent association with the development of epilepsy (OR = 29.8, 99% CI = 23.7–37.3, P < 0.001). Compared with children with risk factors but no epilepsy, those with both epilepsy and risk factors were more likely to have intellectual disabilities (OR = 13.4, 99% CI = 11.9–15.0, P < 0.001). The epilepsy and intellectual disabilities could share the common pathophysiology in the neuronal network.     

Areca catechu (palm tree) nut chewing and seizures: An observational study

ObjectiveThe objective of this study was to report the impact of chronic abuse of Areca catechu nut wrapped in leaf (also known as doma, quid, paan), the fourth most commonly abused psychoactive substance worldwide, on the frequency of seizures among people with epilepsy.MethodsPeople with clinically diagnosed epilepsy (> 14 years old) residing in the Kingdom of Bhutan were surveyed for self-reported Areca catechu use, demographic variables, epilepsy characteristics, and seizure frequency. The relationship between seizure frequency in the prior month and chewing Areca catechu, adjusted for various confounders, was analyzed using multivariable regression models.ResultsThere were 152 people with epilepsy, including 50 chewers (33%) and 102 (67%) nonchewers. The median duration of chewing A. catechu was 62 months (25th, 75th percentiles: 24, 120 months). Chewers consumed an average of three nuts daily. There was no significant difference between chewers and nonchewers in the mean age, proportion of male vs. female, age at first epileptic seizure, or number of antiepileptic drugs presently taken; chewers were more likely to be rural dwellers (p = 0.042). After adjustment for all of the above variables, on average, chewers had 58.7% fewer [95%CI: (− 79.4, − 17.0)] seizures in the prior month, equating to 2.1 fewer [95% CI: (− 3.9, − 0.3)] seizures.ConclusionsOur observational study suggests that the social custom of chewing Areca catechu nut is associated with reduced seizure frequency among people with epilepsy. This association may be due to its natural stimulant properties, a novel antiepileptic property of the nut, or has another, yet unknown explanation.     

Feasibility and acceptability of smartphone applications for seizure self-management in China: Questionnaire study among people with epilepsy

ObjectiveThe aim of this report was to assess the feasibility and acceptability of using smartphone apps for seizure self-management in China.MethodsAll patients with epilepsy were consecutively recruited from the Neurology Epilepsy Prevention and Cure Center of West China Hospital from January 2015 to June 2015. Data on patients' clinical characteristics, mobile phone utilization habits, preferences for contents of apps for seizure self-management, medication adherence, and attitudes toward the use of smartphone apps were collected from 502 patients with epilepsy by questionnaire.ResultsAmong 502 participants, 96.8% had their own mobile phones, and 94.4% owned a smartphone. Although only 9.5% (48/502) of participants had prior knowledge of apps for managing chronic illness, 66.7% (335/502) of participants reported that managing their seizure through an app would be useful. Sixty-five point five percent of participants reported that they would use a smartphone app for seizure self-management if it were free. Patients who were more likely to use an app were those with a low Morisky Scale score (patients with poor medicine adherence), young patients, patients who lived in cities, and patients with frequent seizures (P < 0.001, P = 0.002, P < 0.001, P = 0.01). Patients with higher education and with stable employment were also more likely to use an app (P = 0.001, P < 0.001).ConclusionsThis is the first study on the feasibility and acceptability of smartphone apps for seizure self-management in China. The findings of this study indicate that there is a positive attitude toward using epilepsy apps among patients with epilepsy. Based on patients' positive attitudes toward using epilepsy apps and the current development of mobile health in China, the use of smartphone apps could be a promising strategy for seizure self-management.     

Initial response to antiepileptic drugs in patients with newly diagnosed epilepsy

This study aimed to identify factors predicting the response to antiepileptic drugs in patients with newly diagnosed epilepsy. We prospectively studied 176 patients with newly diagnosed epilepsy. Patients were included if they had a history of two or more clinically definite unprovoked seizures, or had a definite epileptic focus on MRI or epileptiform discharges on electroencephalography if they had suffered only one seizure. The primary endpoint was seizure freedom during the initial 6 months of antiepileptic drug treatment. The secondary endpoint was the time to the first seizure during the maintenance period of antiepileptic drug treatment. A total of 100 patients were included, and seizure freedom for 6 months was achieved in 73 patients. The response to antiepileptic drugs was significantly lower in patients with early age at seizure onset (⩽16 versus >16 years old, odds ratio = 4; 95% confidence interval [CI] 1.5–12.9; relative risk = 1.4; 95% CI 1.1–1.8). In addition, the time to the first seizure during the maintenance period was significantly earlier in patients with age at seizure onset ⩽16 years compared with those with age at seizure onset >16 years on the Kaplan–Meier survival analysis (p = 0.011). Early age at seizure onset is an important factor influencing the response to antiepileptic drugs in patients with newly diagnosed epilepsy.     

Differential impact of contraceptive methods on seizures varies by antiepileptic drug category: Findings of the Epilepsy Birth Control Registry

PurposeThe aim of this study was to determine whether categories of contraception differ in their impact on seizures in women with epilepsy and whether the impact varies by antiepileptic drug category.MethodsRetrospective survey data came from 2712 contraceptive experiences reported by 1144 women with epilepsy. We compared risk ratios for reports of increase and decrease in seizure frequency on hormonal versus nonhormonal contraception, stratified by antiepileptic drug categories.ResultsMore women with epilepsy reported a change in seizures on hormonal (28.2%) than on nonhormonal contraception (9.7%) (p < 0.0001). The risk ratio for seizure increase on hormonal (18.7%) versus nonhormonal contraception (4.2%) was 4.47 (p < 0.0001). The risk ratio for seizure decrease on hormonal (9.5%) versus nonhormonal contraception (5.5%) was 1.71, p < 0.0001. On hormonal contraception, the risk ratio for seizure increase was greater than for decrease (1.98, p < 0.0001). In comparison to combined pills, both hormonal patch and progestin-only pills had greater risk ratios for seizure increase. Depomedroxyprogesterone was the only hormonal method with a greater risk ratio for seizure decrease than combined pills. Seizure increase was greater for hormonal than nonhormonal contraception for each antiepileptic drug category (p < 0.001). On hormonal contraception, relative to the non-enzyme-inducing antiepileptic drug category which had the lowest rate, each of the other categories had significantly greater risks for seizure increase, especially the enzyme-inhibiting (valproate) category (risk ratio = 2.53, p = 0.0002).ConclusionThe findings provide community-based, epidemiological survey evidence that contraceptive methods may differ in their impact on seizures and that this impact may vary by antiepileptic drug category.     

Clinical characteristics and treatment responses in new-onset epilepsy in the elderly

PurposeEpidemiologic studies have shown that the incidence of epilepsy is the highest in the elderly population. Because the elderly constitutes the most rapidly growing population, epilepsy in this group is an important health issue worldwide. To identify the characteristics of epilepsy in the elderly, we reviewed our experience at a tertiary referral center in Japan.MethodsWe searched all electronic medical records of the past 6 years at the epilepsy clinic of the hospital affiliated to our University-affiliated hospital. We defined an elderly person as an individual aged 65 years and above. All patients underwent history and physical examinations, 3 T magnetic resonance imaging and/or computer tomography, and electroencephalogram (EEG). The diagnosis of epilepsy, age of onset, etiology, and antiepileptic medication were recorded.ResultsWe identified 70 patients who developed epilepsy after the age of 65 years. The mean age of seizure onset was 73.1 years and 52.9% patients were males. Complex partial seizures (CPS) without secondarily generalization (n = 33, 47.1%) were most frequent. The most frequent diagnosis was temporal lobe epilepsy (n = 50, 71.4%). Etiological diagnosis was possible in nearly 50% patients, including those with cerebrovascular disease. A clear cause of epilepsy was not found (i.e., non-lesional epilepsy) in 52.8% patients. Interictal EEG revealed focal epileptiform discharges in 72.9% (n = 51) patients. Of the 54 patients who were followed more than 1 year, 42 patients (77.8%) were on antiepileptic monotherapy and 52 patients (96.3%) had been seizure-free for more than 1 year.ConclusionThe most frequent diagnosis in our cohort of elderly persons with new-onset epilepsy was temporal lobe epilepsy. Non-lesional temporal lobe epilepsy was not uncommon. Epileptogenecity was relatively low in elderly patients and they responded well to antiepileptic medication.     

Prevalence of epilepsy in a cohort of patients with multiple sclerosis

IntroductionEpilepsy prevalence is 0.27–1.7% in general population. However, higher figures have been reported in Multiple Sclerosis (MS) patients, suggesting this association is not coincidental.MethodsWe retrospectively reviewed the records of MS patients seen between 2009 and 2012 at Pontificia Universidad Católica of Chile's Multiple Sclerosis Center.ResultsOf 310 MS patients, ten had the diagnosis of epilepsy (3.2%). These patients were younger, and had an earlier onset of symptoms of MS compared to the group without epilepsy (32 vs. 40 years, p = 0.04 and 25 vs. 32 years, p = 0.02, respectively). In 4 patients, seizures were the first MS symptom and the most frequent seizure type was partial secondary generalized (6 patients). MRI showed cortical lesions in all patients. Patients with poor epilepsy control (frequent seizures or development of status epilepticus) had lower brain volumes and worse cognitive performance. All patients received antiepileptic drugs as well as immunomodulatory therapy.ConclusionPatients with epilepsy and MS are younger and have an earlier onset of symptoms. Since most seizures were partial, the presence of cortical lesions and progressive brain atrophy could probably be the pathophysiological mechanism underlying this association.     

Efficacy and tolerability of the first antiepileptic drug in children with newly diagnosed idiopathic epilepsy

PurposeLimited data are available for the effectiveness of the antiepileptic drugs in children in daily clinical practice. The aim of this study was to investigate the efficacy and tolerability of the first prescribed old and new antiepileptic drugs in children with newly diagnosed idiopathic epilepsy during a 12-month period.MethodA total of 289 children (141 females and 148 males) who received phenobarbital (n = 33), valproate (n = 142), carbamazepine (n = 42), oxcarbazepine (n = 38), or levetiracetam (n = 34) as the first-line treatment, were enrolled in the study. Seizure control and the occurrence of adverse events were assessed during a treatment period of 12 months.ResultsOverall, 245 (84.8%) patients remained seizure-free during the study period. The rate of seizure control did not differ significantly between the drug groups (p = 0.099). Forty-four (15.2%) patients including 1 (3.0%) treated with phenobarbital, 22 (15.5%) with valproate, 7 (16.7%) with carbamazepine, 10 (26.3%) with oxcarbazepine, and 4 (11.8%) with levetiracetam had treatment failure. There was no significant difference between seizure-free and failure groups in terms of age, gender, seizure type, and drugs used. Overall, 80 (27.7%) patients had adverse events, of those the most common ones were behavioral problems, nausea and/or vomiting, weight gain, and learning difficulties. The reasons for treatment failures were lack of seizure control in 29 (10.0%) patients and intolerable adverse events in 15 (5.2%) patients.ConclusionIt appears that old (phenobarbital, valproate and carbamazepine) and new antiepileptic drugs (oxcarbazepine and levetiracetam) have similar efficacy and tolerability profiles.Institutional ethic number is 28.3.2013/14.     

Awareness,attitudes toward epilepsy,and first aid knowledge of seizures of hospital staff in Henan,China

AimThe aim of this study was to evaluate awareness of, attitudes toward, and first aid knowledge of seizures of hospital staff in Henan, China.MethodTwo hundred nineteen hospital staff, including doctors, nurses, medical technicians, logisticians, and executives working at tertiary hospitals in Henan, China, completed the survey from March to September in 2016. The data comprised the demographic data section, awareness of epilepsy section, attitude toward epilepsy section, and first aid knowledge of seizure attack section.ResultsThe participants obtained a mean score of 7.48 ± 1.705 on the awareness of epilepsy section, and a mean score of 5.32 ± 1.165 on the first aid knowledge of seizure attacks section. There were significant correlations between educational level (r = 0.187, P = 0.006), occupation (r = − 0.244, P = 0.000), and attitudes toward patients with epilepsy (r = 0.351, P = 0.000) with the awareness of epilepsy. There were significant correlations between age (r = 0.170, P = 0.014), educational status (r = 0.139, P = 0.040), and professional titles (r = 0.197, P = 0.004) with the first aid knowledge of seizures.ConclusionThe study showed that hospital staff had a moderate level of knowledge regarding epilepsy, and they generally displayed a positive attitude. It was also determined that as the awareness of epilepsy increased, they displayed more positive attitudes toward patients with epilepsy. The study also suggests that specialists working on epilepsy should provide more lectures and educational sessions to improve the knowledge of and attitude toward epilepsy and first aid knowledge of seizures among hospital staff.     

Effects of seizure severity and seizure freedom on the health-related quality of life of an African population of people with epilepsy

PurposeThis study aimed at determining the effects of seizure severity and seizure freedom on health-related quality of life (HRQOL) of people with epilepsy (PWE) in the presence of perceived stigma in a sub-Saharan African culture.MethodsHealth-related quality of life was assessed using QOLIE-31 in 93 consecutive adults (56 males and 37 females) with epilepsy. They were stratified into seizure-free, low–moderate seizure severity, and high seizure severity groups based on the seizure type and the number of seizures in the previous 6 months. Other illness variables and sociodemographic variables were also obtained. A 3-item perceived stigma scale was administered. A modified QOLIE-31 (excluding the epilepsy-specific items) was given to 102 age- and sex-matched healthy controls.ResultsThere was moderate negative correlation between seizure severity and mean total HRQOL score as well as scores on the Seizure Worry (p = .000), Overall Quality of Life (p = .000), and Social Function (p = .001) subscales of QOLIE-31. Overall, the healthy control subjects had a higher mean HRQOL score compared with the PWE put together (71.0 + 11.1 vs 64.2 ± 13.6, p = .001). However, there was no difference in the mean HRQOL score between the seizure-free individuals and the healthy controls (p = .270). Seizure severity was associated with HRQOL independent of perceived stigma on a multiple regression analysis.ConclusionThis study provides evidence that seizure severity relates to health-related quality of life in an inverse, graded manner and independent of perceived stigma. Seizure-free people with epilepsy can have quality of life comparable with healthy individuals.     

Evaluating the use of prolonged video-EEG monitoring to assess future seizure risk and fitness to drive

ObjectiveThe use of prolonged video-electroencephalography monitoring (VEM), rather than routine electroencephalography (EEG), in predicting the risk of future seizures in patients with epilepsy is not well studied. A longer period of monitoring could be more likely to capture either ictal or interictal epileptiform activity. This information may better assist clinical decision making on driving fitness. The goal of this study was to evaluate the use of 6-hour prolonged VEM versus routine EEG in the assessment of future seizure risk and driving fitness for patients with epilepsy.MethodsData on consecutive patients referred for 6-hour prolonged VEM were retrospectively analyzed. Criteria were developed that combined EEG findings and clinical factors to determine each patient's fitness to drive. Seizure relapse outcomes were followed over 2 years.ResultsOf 34 patients, 27 were considered safe to drive following prolonged VEM. Five (19%) of these 27 patients had seizure relapses; all had an obvious precipitant(s) identified including sleep deprivation, excessive alcohol, and missed medication doses. Seven of the 34 patients were deemed unsafe to drive. All seven (100%) had seizure relapses, with unprovoked seizures in four patients. The relative risk of seizure in patients deemed unfit to drive was 5.4 (P = 0.00015). If only the routine EEG component of the recordings were used with the criteria, the relative risk would have been 3.4 (P = 0.037), with nearly double the number of active drivers having seizures. The majority of patients (76%) in this study had idiopathic generalized epilepsy, with a relative seizure risk of 4.0 (P = 0.002) for patients deemed unfit to drive in this subgroup. The focal epilepsy group was small (eight patients) and did not quite achieve statistical significance.ConclusionSix-hour VEM improves the evaluation of driving fitness by better predicting the risk of subsequent seizure relapse for idiopathic generalized epilepsy and possibly focal epilepsy. Prolonged monitoring is superior to routine EEG. Ongoing avoidance of seizure-provoking factors remains paramount to driving safety.     

Disturbed dreaming during the third trimester of pregnancy

ObjectiveThe majority of women develop sleep impairments during pregnancy, but alterations in dream experiences remain poorly understood. This study aimed to assess prospectively and comparatively the recall of dreaming and of disturbed dreaming in late pregnancy.MethodsFifty-seven nulliparous, third-trimester pregnant women (mean age ± SD, 28.7 ± 4.06 years) and 59 non-pregnant controls (mean age ± SD, 26.8 ± 4.21 years) completed demographics and psychological questionnaires. A 14-day prospective home log assessed sleep and dream characteristics and the Sleep Disorders Questionnaire measured retrospective dream and disturbed dream recall.ResultsEven though pregnant and non-pregnant women showed similar prospective dream recall (P = 0.47), pregnant women reported prospectively more bad dreams (P = 0.004). More pregnant women (21%) than non-pregnant women (7%) reported a nightmare incidence exceeding moderately severe pathology (>1/week) (P = 0.03). Pregnant women also reported overall lower sleep quality (P = 0.007) and more night awakenings (P = 0.003). Higher prospective recall of bad dreams (r = −0.40, P = 0.002) and nightmares (r = −0.32, P = 0.001) both correlated with lower sleep quality in pregnant women.ConclusionsLate pregnancy is a period of markedly increased dysphoric dream imagery that may be a major contributor to impaired sleep at this time. Further polysomnographic assessments of pregnant women are needed to clarify relationships between sleep and disturbed dream production in this population.     

Seizure precipitants in Dravet syndrome: What events and activities are specifically provocative compared with other epilepsies?

ObjectivesThis study aimed to describe seizure precipitants in Dravet syndrome (DS) compared with other epilepsies.MethodsSeizure precipitants as reported in a Dutch cohort of patients with DS with pathogenic SCN1A mutations (n = 71) were compared with those of a cohort with childhood epilepsy (n = 149) and of a community-based cohort with epilepsy (n = 248); for all three Dutch cohorts, the same type of questionnaire was used. Seizure precipitants were categorized as ‘fever’, ‘visual stimuli’, ‘sleep deprivation’, ‘stress, including physical exercise’, ‘auditory stimuli’, and ‘other’.ResultsFor 70 (99%) of 71 patients with DS, at least one seizure precipitant was recalled by parents. Seizure precipitants that were reported in more than half of the cohort with DS were as follows: having a fever (97%), having a cold (68%), taking a bath (61%), having acute moments of stress (58%), and engaging in physical exercise (56%). Seizure precipitants freely recalled by parents were often related to ambient warmth or cold–warmth shifts (41%) and to various visual stimuli (18%).Patients with DS had more positive seizure precipitant categories (median 4) compared with the cohort with childhood epilepsy (median 2) and the community-based cohort with epilepsy (median 0) (p < 0.001) and showed the highest percentage in each category (all p < 0.001). Within the category ‘stress, including physical exercise’, physical exercise was more often reported to provoke seizures in stress-sensitive patients in the cohort with DS than in the cohort with childhood epilepsy (78% vs. 35%, p < 0.001). In the cohort with childhood epilepsy, physical exercise was more often reported in fever-sensitive children than in other children (25% vs. 12%, p = 0.042).ConclusionsOur study shows a high prevalence of a range of seizure precipitants in DS. Our results underscore elevated body temperature as an important seizure precipitant, whether caused by fever, warm bath, ambient warmth, or physical exercise. Knowledge of these seizure precipitants may improve preventive strategies in the otherwise difficult treatment of DS.     

A community survey of knowledge,perceptions, and practice with respect to epilepsy among traditional healers in the Batibo Health District,Cameroon

ObjectiveThe purpose of this study was to gain an understanding of the approach of traditional healers to epilepsy care, in order to develop a community-based epilepsy care program in Batibo Health District.MethodsWith an 18-item questionnaire, interviews were carried out with 102 traditional healers randomly selected from two associations of traditional healers in the Batibo Health District.ResultsMost traditional healers had heard about epilepsy (98.0%), knew someone with epilepsy (97.8%), or had witnessed a seizure (92.2%). About 40% would object to their children associating with people with epilepsy (PWE), 46.1% would object to their children marrying PWE, and 51% linked the disease to insanity. Though 61.8% of the traditional healers could not offer any treatment for epilepsy, most of them thought it was treatable (74.5%) and would readily refer a patient to the hospital (95.1%). The independent predictors of attitudes were: middle age (30–49 years), P = 0.00003; female gender, P = 0.007; correct knowledge of the cause(s) of epilepsy, P = 0.001; and the misconceptions that epilepsy is contagious and that epilepsy is a form of insanity, P = 0.003 and 0.019, respectively.ConclusionTraditional healers constituted the focus group studied so far in Cameroon that is most familiar with epilepsy. Although they still have some negative practices, the attitudes of traditional healers toward PWE in Batibo Health District are satisfactory, compared with those of the general public and students in the same community. These findings provide evidence for the first time in Cameroon suggesting that collaboration between the modern and traditional health systems with the view of bridging the epilepsy treatment gap is possible. There is a need to train traditional healers in epilepsy care in our context.     

Six-month efficacy of the Ketogenic diet is predicted after 3 months and is unrelated to clinical variables

ObjectiveThe aim of this study was to evaluate the 6-month efficacy of a Ketogenic diet (KD) in children with drug-resistant epilepsy and to analyze the associated factors that affect the efficacy of a KD.MethodsEighty-seven pediatric patients with drug-resistant epilepsy who followed a KD for at least 6 months were included in this study. The efficacy of a KD was assessed based upon the seizure frequency, as recorded by parents and caregivers. The number of cases and the degree of efficacy in different age ranges were also considered. The effects of gender, age, seizure type, etiology, blood glucose and ketone levels, seizure frequency before the diet, and cognition on the length of time on a KD were analyzed.Results(1) There was no significant correlation between the length of time on a KD and efficacy (χ² = 2.31, P = 0.51). The 3-month efficacy of a KD was 51%, which did not further increase when the course was extended to 6 months. (2) There was a positive correlation between increased cognition and the efficacy of a KD after 3 months (γ = 0.31, P = 0.003). (3) The efficacy analysis of 3-month treatment with a KD revealed, with respect to seizure types, that there were 37 patients with multiple seizure phenotypes and 50 patients with a single seizure phenotype. The overall efficacy of a KD in the group with multiple seizure phenotypes was 61%. The efficacy of a KD was not statistically associated with a coexisting syndrome or a type of syndrome; however, the efficacy of a KD had a tendency to be increased in certain types of syndromes. The overall efficacy in the group with a single seizure phenotype was 87%, and the efficacy was not associated with seizure type. (4) The 3-month efficacy of a KD was not correlated with age, gender, etiology, blood glucose or ketone levels, or the seizure frequency before treatment.ConclusionAn observation time of 3 months is appropriate for assessing the efficacy of a KD in treating children with drug-resistant epilepsy. The factors that likely influence the efficacy of a KD are unclear, but our study suggests that incorporating more patient samples will help determine whether patients with certain syndromes can benefit from a KD.
