Objectives

Patients with epilepsy are ineligible to drive until seizure free for an appropriate period given the risk of a seizure-related motor vehicle accident. Driving restrictions also apply to patients after their first-ever seizure. However, it is unclear whether a longer period of non-driving is required if the first seizure occurred while driving. The association of a seizure with driving may have been by chance or due to a specific factor or trigger increasing the likelihood of a seizure. More data is required to inform driving restrictions.

Methods

This study was based on prospectively collected data of consecutive adults with a first-ever seizure seen at a hospital-based first seizure clinic between 2000 and 2015. We examined the clinical, EEG and imaging features of patients who were eligible to drive, comparing patients with their first seizure while driving (FSWD) to those who had an awake first seizure at other times (FSOT) to explore possible differences clinical features and likelihood of seizure recurrence, evaluated using survival analysis.

Results

57 patients with a FSWD were compared to 1335 patients with FSOT. 80 % of FSWD resulted in loss of control of the vehicle, 64 % with a crash and almost half of patients sustaining an injury. Fifty of 57 FSWD were related to an unprovoked first seizure. FSWD patients had a higher cumulative likelihood of having a second seizure than FSOT patients (50.1 % vs 36.2 % at 1 year, 57.9 % vs 41.7 % at 2 years and 65.1 % vs 47.8 % at 5 years; p = 0.003), with the conditional risk of seizure recurrence only falling consistently below 2.5 %/month at twelve months after the first seizure. Independent predictors of seizure recurrence on multivariable analysis were epileptogenic lesion on imaging, unprovoked (vs acute symptomatic) first seizure, epileptiform abnormality on EEG, focal seizure; and for those with unprovoked first seizure, FSWD and higher Rankin score were also predictors.

Conclusions

First seizure whilst driving is an independent predictor of seizure recurrence for unprovoked seizures, supporting a longer period of seizure freedom before returning to driving.

Background

Epilepsy prevalence in sub-Saharan Africa is high with a significant treatment gap. In this context, epilepsy presents substantial challenges to effective and safe reproductive and maternal healthcare. To improve this, it is important to understand the views and perceptions of healthcare professionals delivering epilepsy care to this population.

Methods

This study uses an online questionnaire which asked healthcare professionals (both from nursing and medical backgrounds) who work in sub-Saharan African countries to rate a set of pre-established options designed with the feedback of a local focus group of epilepsy experts from countries targeted. The questionnaire consisted of 21 questions and was a mix of multiple choice and Likert scale questions on managing reproductive health in women in local settings.

Results

Of 203 healthcare professionals respondents from over 10 countries majority were doctors (48%) or nurses (36%). The Gambia (28.6%), Nigeria (22.2%), Cameroon (13.3%) and Zambia (9.4%) accounted for nearly three-quarters of respondents. Over half (54%) felt that they have the necessary training to counsel women with epilepsy on reproductive health and pregnancy. Only 40% reported they regularly discuss family planning. Carbamazepine was reported to be the most used anti-seizure medication (ASM) for childbearing age women. Key challenges outlined were epilepsy awareness among patients and their families, information deficit on ASMs and pregnancy and access to a sufficient range of ASMs.

Conclusion

Understanding the challenges faced by health professionals in sub-Sharan Africa, provides better comprehension of the specific “treatment-education gap” in counselling women with epilepsy on ASM risks and benefits.

Background and Purpose

Stigma is a pervasive barrier for people living with epilepsy (PLWE) and can have substantial negative effects. This study evaluated clinical correlates of perceived stigma in a research sample of PLWE considered to be at high risk due to frequent seizures or other negative health events.

Methods

Analyses were derived from baseline data from an ongoing Centers for Disease Control and Prevention (CDC)-funded randomized controlled trial (RCT) testing an epilepsy self-management approach. Standardized measures assessed socio-demographics, perceived epilepsy stigma, epilepsy-related self-efficacy, epilepsy self-management competency, health literacy, depressive symptom severity, functional status, social support and epilepsy-related quality of life.

Results

There were 160 individuals, mean age of 39.4, (Standard deviation/SD=12.2) enrolled in the RCT, 107 (66.9 %) women, with a mean age of epilepsy onset of 23.9 (SD 14.0) years. The mean seizure frequency in the prior 30 days was 6.4 (SD 21.2). Individual factors correlated with worse perceived stigma were not being married or cohabiting with someone (p = 0.016), lower social support (p < 0.0001), lower self-efficacy (p < 0.0001), and lower functional status for both physical health (p = 0.018) and mental health (p < 0.0001). Perceived stigma was associated with worse depressive symptom severity (p < 0.0001). Multivariable linear regression found significant independent associations between stigma and lower self-efficacy (β −0.05; p = 0.0096), lower social support (β −0.27; p = 2.4x10^-5, and greater depression severity (β 0.6; p = 5.8x10^-5).

Conclusions

Perceived epilepsy stigma was positively correlated with depression severity and negatively correlated with social support and self-efficacy. Providers caring for PLWE may help reduce epilepsy stigma by screening for and treating depression, encouraging supportive social relationships, and providing epilepsy self-management support. Awareness of epilepsy stigma and associated factors may help reduce some of the hidden burden borne by PLWE.

Status epilepticus (SE) carries risks of morbidity and mortality. Experimental studies have implicated the entorhinal cortex in prolonged seizures; however, studies in large human cohorts are limited. We hypothesised that individuals with temporal lobe epilepsy (TLE) and a history of SE would have more severe entorhinal atrophy compared to others with TLE and no history of SE.

357 individuals with drug resistant temporal lobe epilepsy (TLE) and 100 healthy controls were scanned on a 3T MRI. For all subjects, the cortex was segmented, parcellated, and the thickness calculated from the T1-weighted anatomical scan. Subcortical volumes were derived similarly. Cohen’s d and Wilcoxon rank-sum tests respectively were used to capture effect sizes and significance.

Individuals with TLE and SE had reduced entorhinal thickness compared to those with TLE and no history of SE. The entorhinal cortex was more atrophic ipsilaterally (d = 0.51, p $<$ 0.001) than contralaterally (d = 0.37, p $=$ 0.01). Reductions in ipsilateral entorhinal thickness were present in both left TLE (n = 22:176, d = 0.78, p $<$ 0.001), and right TLE (n = 19:140, d = 0.31, p = 0.04), albeit with a smaller effect size in right TLE. Several other regions exhibited atrophy in individuals with TLE, but these did not relate to a history of SE.

These findings suggest potential involvement or susceptibility of the entorhinal cortex in prolonged seizures.

The new-onset refractory status epilepticus (NORSE)/febrile infection-related epilepsy syndrome (FIRES) Family Registry contributes to a systematic effort to collect clinical and epidemiological information on individuals affected by NORSE/FIRES. We explore diagnostic and prognostic information provided to patients and their families, their satisfaction with the communication, and utilisation of palliative care services during acute hospitalization. Communication about the diagnosis of NORSE/FIRES to families has improved since the publication of consensus definitions in 2018, with families being more likely to be told about NORSE/FIRES after 2018. Families rate the quality of prognostic information as being moderate. Palliative care services were involved in a minority of patients. Understanding and characterizing the prevalence and satisfaction of diagnostic and prognostic conversations is important for improving overall care, the quality of physician-patient-family relationships, and the recovery process for those affected by NORSE/FIRES.

Aim

This study aimed to examine seizure self-efficacy and quality of life of children with epilepsy and to evaluate the relationship between these parameters.

Method

The study was conducted between November 2022 and November 2023 in the Pediatric Neurology Outpatient Clinic of a university hospital with 200 children aged 9–14 who met the inclusion criteria and accepted the study. The data were collected using the “Child Descriptive Form,” “Seizure Self-Efficacy Scale in Children with Epilepsy,” and “KIDSCREEN-27 Health-Related Quality of Life Scale”. The data were evaluated using the IBM SPSS Statistics Standard Concurrent User V 26 statistical package program. Number, percentage, mean-standard deviation, median, minimum and maximum values, Cronbach’s Alpha coefficient, Shapiro Wilk normality test, Independent Sample t-test, Analysis of Variance (ANOVA), Bonferroni test, Pearson correlation coefficient, linear regression analysis, Durbin-Watson value and normality of residuals Q-Q graphs were used in the evaluation of the data. A value of p < 0.05 was considered statistically significant.

Results

It was determined that 53 % of the children participating in the study were male, and the median age was 12 years. The mean total score of the seizure self-efficacy scale was 3.13 ± 1.03, and the mean total score of the health-related quality of life scale was 89.83 ± 15.63. There was a statistically significant positive correlation between the dimension of individual seizure control and total score of health-related quality of life and physical well-being, emotional well-being and social support, and peer dimensions (p < 0.05). A statistically significant positive correlation was determined between the effect of environment on seizure control and health-related quality of life total score, physical well-being, social support, and peer and school environment dimensions (p < 0.05). A statistically significant positive correlation was determined between seizure self-efficacy total score and health-related quality of life total score and physical well-being, emotional well-being, social support, and peer dimensions (p < 0.05).

Conclusion

The study results reveal that high self-efficacy levels of children with epilepsy improve the quality of life of children with epilepsy.

2-deoxy-D-glucose (2DG) has been proposed as a potential antiseizure treatment based on seizure suppressive actions in multiple acute and chronic seizure models, including models of status epilepticus (SE). Here we summarize recently completed preclinical toxicological studies of single doses of an intravenous formulation of 2DG supporting potential safety of 2DG for acute treatment of SE and acute repetitive seizures (ARS).

The “crowding” effect (CE), wherein verbal functions are preserved presumably at the expense of nonverbal functions, which diminish following inter-hemispheric transfer of language functions, is recognized as a specific aspect of functional reorganization, offering an insight about neural plasticity in children with neural insult to the dominant hemisphere. CE is hypothesized as a marker for language preservation or improvement after left-hemispheric injury, yet it remains challenging to fully discern it in preoperative evaluation. We present a novel DWI connectome (DWIC) approach to predict the presence of CE in 24 drug-resistant epilepsy (DRE) patients with a left-hemispheric focus and 29 young healthy controls. Psychometry-driven DWIC analysis was applied to create verbal and non-verbal modular networks. Local efficiency (LE) was assessed at individual regions of the two networks and its Z-score was compared to predict the presence of CE. Compared with a traditional organization (TO) group, wherein verbal functions are adversely affected, while non-verbal functions are preserved, the CE group showed significantly higher Z-scores in verbal network and significantly lower Z-scores in non-verbal network, corresponding to network reorganization in CE. A larger number of antiseizure drugs was significantly associated with more decreased Z-score in the right non-verbal network of the CE group and left verbal network of the TO group. These findings hold great potential to identify DRE patients whose verbal/language skills may over time be preserved due to effective inter-hemispheric reorganization and identify those whose verbal/language impairments may persist due to lack of inter-hemispheric reorganization.

Epilepsy, a chronic non-communicable disease of the brain, is one of the most common neurological diseases globally that affects people of all ages. The existence of medical, neurological, psychiatric, and cognitive comorbidities has always undermined the available advanced treatment strategies for epilepsy. New-generation antiepileptic drugs being less successful in completely controlling the seizures and observance of complex diseases, including drug-resistant cases, have provided scope for integrating and incorporating the therapeutic modalities of Ayurveda, the ancient Indian art of holistic medicine, in the effective management of epilepsy. Epilepsy can be correlated to Apasmara, described in the classics of Ayurveda as the transient appearance of unconsciousness with loathsome expression due to derangement of memory, intelligence, and mind. The multifaceted therapeutic approach of Ayurveda, which involves pharmacologic and nonpharmacologic measures, purificatory and pacifying procedures, herbal and herbo-mineral formulations, disease, and host-specific approaches, have enhanced the potential of not only relieving symptoms but also modifying the pathophysiology of the disease. Newer paradigms of research in Ayurveda, along with holistic and integrative approaches with contemporary medicine, can not only benefit the existing healthcare system but also impact future healthcare management in epileptology research. This cursory literature review is an earnest attempt to identify, evaluate, and summarize various studies and provide a comprehensive insight into the potential of Ayurveda in understanding and treating epilepsy.

Purpose

To analyze the characteristics of cerebral blood flow changes of poor sleep quality in people with epilepsy(PWE).

Methods

90 PWE treated in The General Hospital of Ningxia Medical University from December 2021 to September 2023 were divided into poor sleep quality group (PSQG) and good sleep quality group (GSQG) according to the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI), to compare the differences in cerebral perfusion between the two groups of patients, so as to summarize the characteristics of cerebral blood flow changes of poor sleep quality in PWE.

Results

The positive rate of interictal single-photon emission computed tomography/computed tomography (SPECT/CT) was 76.7 %(69/90), which showed localized cerebral hypoperfusion. There was no statistical difference between the two groups of PSQG (N=29) and GSQG (N=61) in terms of the positive rate of SPECT/CT, the number of hypoperfusion foci, and the range of hypoperfusion foci. In PSQG and GSQG, 9 patients(31.0 %) and 6 patients(9.8 %) showed hypoperfusion in the right parietal lobe, respectively, and the difference between the two groups was statistically significant (P=0.017). There was no statistical difference the rate of the interictal epileptiform discharges (IEDs) and the brain area of IEDs in electroencephalography(EEG) between the two groups.

Conclusion

SPECT/CT of poor sleep quality in PWE demonstrated hypoperfusion in the right parietal lobe.
