Driving and Epilepsy: a Review of Important Issues

License to drive vehicles: Legal aspects and clinical variables in Brazilian patients with epilepsy

In epilepsy, there may be impairment of psychosocial aspects, including restrictions for the license to drive vehicles.

OBJECTIVE

To evaluate the license to drive a vehicle in patients with epilepsy according to Brazilian legislation and to relate it to demographic and clinical variables.

METHODOLOGY

The license-to-drive vehicle rate was related to the demographic and clinical data of 305 patients with epilepsy.

RESULTS

The mean age was 49.2 years, with 176 females, the mean education was six years, and structural epilepsy occurred in 203 patients. The license to drive vehicles occurred in 35 (11.5 %) patients. In the multiple logistic regression analysis, with stepwise variable selection criteria, it was observed that the variables that together best predict the possession of a driving license are education (p-value = 0.012; OR = 1.15 (1.03, 1.29)), sex (p-value = 0.001; OR = 4.05 (1.80, 9.68)), marital status (p-value = 0.022; OR = 2.67 (1.18, 6.41)), neurological examination (p-value = 0.029; OR = 3.62 (1.25, 13.22)) and number of antiseizure medication (ASM) in use (p-value = 0.019; OR = 3.04 (1.26, 8.28)). The license did not comply with Brazilian legislation in 21 (60 %) patients. In nine patients, the practice violated the law due to the type of vehicle, and in 12 patients, due to the maintenance of seizures in the last year. Patients with non-legal aspects of the license were older, had less education, were male, and had a spouse.

CONCLUSION

In patients with epilepsy, the rate of license to drive vehicles was low, and it was associated with higher schooling, males, having a spouse, having no alterations in the neurological examination, and the use of a single ASM. The non-compliance with current legislation was high, suggesting a lack of information or denial of the disease.

Electroencephalographic compatibility with fitness to drive: A nationwide survey among Swiss neurologists

OBJECTIVE

The Swiss guidelines for driving with epilepsy require that electroencephalogram (EEG) findings must be compatible with the fitness to drive (FTD) without specifying any criteria. This nationwide survey investigated how Swiss neurologists implement this requirement in clinical practice.

METHODS

An online survey, including 19 EEG examples and statements about the compatibility of the EEG with FTD, was distributed to all members of the Swiss Society of Clinical Neurophysiology and all Swiss neurological clinics with residency programs. Descriptive statistics and Fleiss' Kappa for inter-rater agreement were performed.

RESULTS

102 participants (37% female, 45% <45 years) completed the survey, with 15% primarily working in a specialized epileptology center (EPI), 55% in a hospital setting without epileptological focus (HOS), and 30% in private practice (PP). Most participants of all three groups regarded EEG normal variants as compatible with FTD, while hyperventilation-induced rhythmic slowing and some pathological patterns (e.g., frontal and temporal intermittent rhythmic delta activity [FIRDA, TIRDA], focal interictal epileptiform discharges [IED], focal seizure) were evaluated more heterogeneously. The EEG inter-rater agreement for EPI was 0.4; 0.31 for PP; and 0.24 for HOS. No consensus was found for acceptable duration for generalized or focal IEDs. Among all participants, evaluation by an epilepsy center (85%) and reaction-time testing (67%) were evaluated as the most useful additional examinations. However, reaction-time testing is rarely or never performed by 58%. Most supported EEG results as part of the FTD assessment and demanded more research (both 82%).

SIGNIFICANCE

Our survey indicates considerable heterogeneity among Swiss neurologists when evaluating the EEG findings for FTD. Inter-rater agreement in all three groups was fair, with highest agreement among epileptologists. We noted a discrepancy between the usefulness and actual application of reaction-time testing. More training and research are warranted to achieve rater-independent consistency for FTD evaluation.

PLAIN LANGUAGE SUMMARY

In Switzerland, neurologists must consider the findings from EEG (brain waves) exams to evaluate driving safety in people with epilepsy. We surveyed Swiss neurologists, asking their opinions on this matter. We found that opinions differ among individual doctors, with the highest agreement among epilepsy specialists. We also found that some additional tests, such as reaction-time testing, are perceived as useful but are rarely performed. The participating neurologists supported considering EEG results for driving fitness assessments but favored more precise guidelines and research.

Seizure-Related Head Injuries: A Narrative Review

Epilepsy is one of the most common neurological diseases. Epileptic seizures very often result in head injuries that may lead to many adverse consequences, both acute and chronic. They contribute to the need for hospitalization, modification of treatment, and a general decline in social productivity. The objective of our review is to characterize and assess management aspects of seizure-related head injuries (SRHIs) as an important and frequent clinical problem present in emergency department settings. PubMed and other relevant databases and websites were systematically searched for articles on traumatic brain injuries connected with the occurrence of seizures published from inception to 9 April 2024; then, we reviewed the available literature. Our review showed that SRHIs can lead to various acute complications, in some cases requiring hospitalization and neurosurgical intervention. Long-term complications and cognitive decline after injury might be present, eventually implying a negative impact on a patient's quality of life. Despite being frequent and clinically important, there are still no widely accepted, uniform recommendations for the management of patients with SRHIs. As such, a concise and standardized protocol for the management of seizure-related head injuries in emergency departments is worth consideration.

Tele-Neuropsychology: From Science to Policy to Practice

OBJECTIVE

The primary aim of this paper is to accelerate the number of randomized experimental studies of the reliability and validity in-home tele-neuropsychological testing (tele-np-t).

METHOD

We conducted a critical review of the tele-neuropsychology literature. We discuss this research in the context of the United States' public and private healthcare payer systems, including the Centers for Medicare & Medicaid Services (CMS) and Current Procedural Terminology (CPT) coding system's telehealth lists, and existing disparities in healthcare access.

RESULTS

The number of tele-np publications has been stagnant since the onset of the COVID-19 pandemic. There are less published experimental studies of tele-neuropsychology (tele-np), and particularly in-home tele-np-t, than other tele-np publications. There is strong foundational evidence of the acceptability, feasibility, and reliability of tele-np-t, but relatively few studies of the reliability and validity of in-home tele-np-t using randomization methodology.

CONCLUSIONS

More studies of the reliability and validity of in-home tele-np-t using randomization methodology are necessary to support inclusion of tele-np-t codes on the CMS and CPT telehealth lists, and subsequently, the integration and delivery of in-home tele-np-t services across providers and institutions. These actions are needed to maintain equitable reimbursement of in-home tele-np-t services and address the widespread disparities in healthcare access.

Impact of Seizures While Driving Prior to Diagnosis in People With Focal Epilepsy: Motor Vehicle Accidents and Time to Diagnosis

OBJECTIVES

To identify the type, frequency, and consequences of seizures while driving (SzWD) in people with epilepsy before diagnosis.

METHODS

We performed a retrospective cohort study using the Human Epilepsy Project (HEP) to identify prediagnostic SzWD. Clinical descriptions from seizure diaries and medical records were used to classify seizure types and frequencies, time to diagnosis, and SzWD outcomes. Data were modeled using multiple logistic regression to assess for factors independently associated with SzWD.

RESULTS

32 prediagnostic SzWD were reported among 23/447 (5.1%) participants. Of them, 7 (30.4%) had more than 1. Six participants (26.1%) experienced SzWD as their first lifetime seizure. Most SzWD were focal with impaired awareness (n = 27, 84.4%). Of participants who had motor vehicle accidents (MVAs), 6 (42.9%) had no recollection. SzWD led to hospitalization in 11 people. The median time from first seizure to first SzWD was 304 days (IQR = 0-4,056 days). The median time between first SzWD and diagnosis was 64 days (IQR = 10-176.5 days). Employment was associated with a 3.95-fold increased risk of SzWD (95% CI 1.2-13.2, p = 0.03), and nonmotor seizures were associated with a 4.79-fold increased risk (95% CI 1.3-17.6, p = 0.02).

DISCUSSION

This study identifies the consequences of seizure-related MVAs and hospitalizations people experience before epilepsy diagnosis. This highlights the need for further research aimed at improving seizure awareness and improving time to diagnosis.

The Application of Deep Learning to Electroencephalograms, Magnetic Resonance Imaging, and Implants for the Detection of Epileptic Seizures: A Narrative Review

Epilepsy is a neurological disorder characterized by recurrent seizures affecting millions worldwide. Medically intractable seizures in epilepsy patients are not only detrimental to the quality of life but also pose a significant threat to their safety. Outcomes of epilepsy therapy can be improved by early detection and intervention during the interictal window period. Electroencephalography is the primary diagnostic tool for epilepsy, but accurate interpretation of seizure activity is challenging and highly time-consuming. Machine learning (ML) and deep learning (DL) algorithms enable us to analyze complex EEG data, which can not only help us diagnose but also locate epileptogenic zones and predict medical and surgical treatment outcomes. DL models such as convolutional neural networks (CNNs), inspired by visual processing, can be used to classify EEG activity. By applying preprocessing techniques, signal quality can be enhanced by denoising and artifact removal. DL can also be incorporated into the analysis of magnetic resonance imaging (MRI) data, which can help in the localization of epileptogenic zones in the brain. Proper detection of these zones can help in good neurosurgical outcomes. Recent advancements in DL have facilitated the implementation of these systems in neural implants and wearable devices, allowing for real-time seizure detection. This has the potential to transform the management of drug-refractory epilepsy. This review explores the application of ML and DL techniques to Electroencephalograms (EEGs), MRI, and wearable devices for epileptic seizure detection. This review briefly explains the fundamentals of both artificial intelligence (AI) and DL, highlighting these systems' potential advantages and undeniable limitations.

What are the considerations when initiating treatment for epilepsy in children?

INTRODUCTION

There is a very wide spectrum of epilepsies and developmental and epileptic encephalopathies that affect children, from self-limited forms, not necessarily requiring treatment, to severe drug-resistant ones.

AREAS COVERED

In this perspective, the authors discuss the main factors to consider before drug prescription in children, considering the most recent clinical research, including age, seizure type, epilepsy syndrome, etiology, efficacy and safety profile, comorbidities, gender, available formulations, costs and drug coverage, and regulatory issues. The literature search was conducted through a PubMed search on antiseizure medications for patients aged 0-18, with respect to each of the aforementioned factors, and by checking the reference lists of relevant papers.

EXPERT OPINION

The most expanding field of research and innovation for clinical practice is precision medicine, which addresses the holistic treatment of genetic epilepsies and developmental and epileptic encephalopathies. It achieves this by addressing their detrimental effects on synapses, neurotransmission, and cellular signaling pathways with the double aim to treat seizures and to rescue neurodevelopmental trajectories, but also the issue of adverse events and drug resistance through pharmacogenomics.

Maximizing Quality of Life in Children with Epilepsy

Arguably significant progress and improvement in the medical and surgical treatments of seizures and epilepsy in children have occurred; however, there have been relatively fewer efforts in optimizing the care of lifestyle complications related to the disease state. Many patients have significant behavioral and mental health comorbidities, including ADHD (attention deficit hyperactivity disorder), which should be treated. After epilepsy surgery, only seizure freedom results in improved quality of life (QOL). Improved compliance leads to better seizure control and ensuring that caregivers have a rescue treatment helps empower patients. Education and improving seizure illness perception is beneficial. Cannabidiol may have benefits other than seizure control. The majority of children are mainly concerned about the stigma attached to having epilepsy. Driving affecting older children is discussed. Restrictions on these children should be minimized and enabling regular activities maximized.

Driving restrictions in patients with seizures; a review of the regulations from the English-speaking nations

PURPOSE

We investigated the existing regulations about driving eligibility and restrictions for persons with seizures in all English-speaking countries in the world. We aimed to identify: 1) Is there a distinction between epilepsy and functional seizures (FS) in the regulations? 2) What is the required seizure-free period before a person with seizure regains their driving eligibility?

METHODS

First, we identified all the English-speaking countries in the world. Then, we referred to the website of the Department of Motor Vehicles or its equivalent in each nation or we searched the Google engine with the name of each specific nation and "driving" and "epilepsy".

RESULTS

There are 59 English-speaking countries in the world. For 37 nations, the data on regulations about driving eligibility for persons with seizures were lacking. Only the UK has made distinctions between epilepsy and FS. The required seizure-free period before a person with seizure regains their driving eligibility varied significantly between nations. Not all nations have made distinctions between private driving and commercial driving. Finally, only some nations have specific rules and regulations for different scenarios (e.g., provoked seizures vs epilepsy, or nocturnal seizures only, etc.) CONCLUSION: Many English-speaking nations in the world do not have explicit rules and regulations about driving eligibility and restrictions for persons with seizures. International scientific organizations should do more to provide appropriate and personalized guidelines for different scenarios of seizures, so the governments can adopt appropriate regulations.

Exploring the influence of telehealth on patient engagement with a multidisciplinary Non-Epileptic Seizure (NES) Clinic during the COVID-19 pandemic

The ILAE task force has identified a gap in treatment access for patients with nonepileptic seizures (NES) [1]. Access to multidisciplinary treatment clinics for adults with NES is limited with only 18 institutions delivering care across the United States [2]. Patient engagement has been low in the University of Colorado, NES Clinic treatment program despite our clinic's status as the only clinic of its kind in the mountain west. We analyzed patient factors of those who engaged in treatment before and after COVID-19 regulations were imposed and found a 23.6% increase in treatment engagement using telehealth. Those who engaged using telehealth were more likely to be of white race, of non-Hispanic ethnicity, publicly insured, employed, have a Charlson Comorbidity Index (CCI) of zero, a daily seizure rate of 0-1, did not have suicidal ideation or attempts, and live greater than 25 miles from the NES clinic. Delivering NES treatment via telehealth reduced the logistical and psychological barriers to initiating recovery and with a severe lack of accessible treatments for patients with NES, barrier reduction is necessary. This study describes patient factors that result in higher engagement with NES treatment using telehealth and emphasizes the importance of telehealth utilization to improve access to available treatment.

Comparison of care accessibility, costs, and quality with face-to-face and telehealth epilepsy clinic visits

During the COVID-19 pandemic, restrictions on reimbursement for telehealth visits were lifted and this visit type was suddenly available to patients around the United States of America. Telehealth visits offer potential cost savings for patients and families, which may vary by region of the world studied. Also, aggressiveness of the care patients receive may differ, and patients or families may be more likely to choose one visit type over another based on seizure control. This is a prospective face-to-face clinic versus telehealth clinic visit comparison study involving patients with seizures, their legal guardians, and caretakers who attend clinic. We compared travel distance, work-related factors, childcare, satisfaction of care, changes in seizure medication or diagnostics tests ordered, and willingness to cancel appointments to better understand the behavioral patterns of patients, caretakers, and providers. Our results indicate that many patients and families still prefer in-person interactions with their medical providers. Patient and family satisfaction levels were equal with both visit types. No significant difference was seen in medical management between face-to-face and telehealth visits. Also, prior seizure control did not dictate the type of visit chosen. Telehealth participants were significantly more willing to cancel appointments if asked to switch to face-to-face then face-to-face participants asked to complete telehealth visits. Surprisingly, we found that patients and families choosing telehealth were not statistically more likely to be employed or take less time off work. Also, distance from home to office was not significantly shorter for participants choosing face-to-face visits. Offering a combination of telehealth and face-to-face visits appears to be the optimal strategy in caring for patients with controlled and uncontrolled seizure disorders to ensure adherence with clinic visits and satisfaction with care. Our study suggests that providers are equally willing to adjust medications or order additional diagnostic testing regardless of visit type. Patients and families may be less likely to cancel telehealth visits than face-to-face visits; this finding may translate to improved seizure control and long-term decreased cost of care.

Characterizing the driving dilemma among patients with psychogenic nonepileptic seizures: A single-center prospective cohort study

OBJECTIVE

Driving is a critical topic to counsel among patients with epileptic seizures (ES) and psychogenic nonepileptic seizures (PNES), with significant legal and public health implications. This prospective cohort study examined the frequency of ES and PNES in a single institution's Epilepsy Monitoring Unit (EMU) and assessed driving-related issues between each group.

METHODS

Adult patients from the Mayo Clinic Arizona Epilepsy Monitoring Unit (EMU) were given comprehensive surveys addressing driving history. Descriptive analysis and statistics were used to summarize differences between patients with ES and PNES. Differences between patients with epilepsy and PNES were determined by Pearson chi-square.

RESULTS

Nearly half (n = 75/163) of all patients admitted to the EMU were diagnosed with PNES. Although the PNES group had a statistically significant higher frequency of events (p = 0.01), 87.7% of these patients reported compliance with the driving law recommendations, suggesting a trend that patients who have been counseled regarding fitness-to-drive are likely to follow the recommendation. One-third of patients with PNES reported an event while operating a motor vehicle and 8% (n = 2/25) resulted in a motor vehicle collision severe enough to require hospitalization. In contrast to those with ES, 25% of patients reported a typical event while driving and 25% (n = 2/8) of those resulted in a collision requiring hospitalization. The incidence of habitual events while driving is higher in the population with PNES (n = 25) when compared to those with ES (n = 8); however, it appears that patients with PNES were less likely to become involved in an accident resulting in seriously bodily injury than in ES.

CONCLUSIONS

Compared to patients with PNES, patients with ES have less frequent events but more severe collisions. This study reinforces the need for diligent driving counseling to help prevent driving-related injuries in patients with PNES and ES.

Individual prediction of motor vehicle accidents for patients with epilepsy

The objective of the study was to design a clinically useful tool to predict the risk of seizure-related motor vehicle accidents (MVAs) for people with epilepsy (PWE). Participants were patients who visited our epilepsy center in West China Hospital from October 2012 to October 2019 and were divided into a primary cohort and a validation cohort. Ultimately, we included 525 patients in the primary cohort and 86 patients in the validation cohort. Proportional hazard regression was performed to measure the prognostic factors of car accidents. The outcome was used to create a nomogram model. The final model had 7 factors, with a C-index of 0.85 (95% CI, 0.80-0.91), to predict the possibility of non-MVA for PWE. For the validation cohort, the C-index was 0.83 (95% CI, 0.72-0.95). This nomogram model can offer more individualized advice to PWE who are still driving by estimating the risk of car accidents.

Epilepsy: A Clinical Overview

The diagnosis and treatment of seizures and epilepsy is a common task of the physician. Approximately 1 in 10 people will have a seizure during their lifetime. Epilepsy is the tendency to have unprovoked seizures. Epilepsy is the fourth most common neurological disorder and affects 1 in 26 people in the United States and 65 million people worldwide. Evaluation of a patient presenting with a seizure involves excluding an underlying neurologic or medical condition, classifying the seizure type and determining if the patient has epilepsy. Proper treatment requires accurate diagnosis of the epilepsy type and syndrome and use of a medication that is effective and without adverse effects. Most patients can achieve complete seizure control with medication, but if medication is unsuccessful, surgical treatment can be an option. Special situations in the care of people with epilepsy include status epilepticus, women with epilepsy, the older adult, and safety issues.

Improving public stigma, sociocultural beliefs, and social identity for people with epilepsy in the Aseer region of Saudi Arabia

•

An update of the data reported previously in 2016 in Aseer region.

•

The level of education and awareness regarding epilepsy in Aseer region has improved recently.

•

The belief in spiritual and traditional therapies has decreased, considering them as additional options.

Differences in the sociocultural practice and biases against people with epilepsy (PWE) largely contribute to the development of stigmatization. In this study, we evaluated factors that impact stigma for PWE involved in evolution and maintenance to report changes in the public awareness and cultural practices. We performed a cross-sectional study in which data were collected from a self-administered electronic survey composed of 33 items targeting the population in the Aseer region. Feedback response was obtained from 937 respondents. Of these, 921 participants (98.3%) had heard or read about the disorder previously. Approximately 84.8% believed that epilepsy was one of the brain disorders. 95.8% disagreed that epilepsy was due to a contagious disease. However, 40.1% of the responders were convinced that it was the result of a spiritual reason. Still, more than 9% believed treating PWE should be approached spiritually. About 75% felt that epilepsy could be the results of a test delievered by God. In addition to the clinical impact from seizures in PWE, it carries a social label and public stigma that influences one's social prognosis. Raising awareness through campaigns would improve the knowledge and practices of the population and hence provide a healthier environment for PWE, alleviating feelings of stigma, and improving their quality of life.

Knowledge about epilepsy and factors associated with attitudes toward marrying, employing, and driving people with epilepsy: A cross-sectional survey of Asokore Mampong community dwellers in Ghana

BACKGROUND

Due to lack of information and illiteracy, epilepsy remains a stigmatized disease in sub-Saharan Africa.

OBJECTIVES

The main aim of the study was to determine, among community dwellers in Asokore Mampong Municipality (Ghana): (i) the knowledge on risk factors, signs and symptoms, management of epilepsy, and (ii) factors associated with attitudes toward marrying, employing, or driving people with epilepsy (PWE).

METHODS

A cross-sectional study of 100 randomly selected individuals aged 18 years and older in Asokore Mampong Municipality was conducted in February 2019. A self-administered questionnaire was used to assess the knowledge about epilepsy and attitudes toward marrying, employing, and driving people with epilepsy. Frequencies and corresponding percentages were used to describe the study participants, their knowledge regarding epilepsy and attitudes toward marrying, employing, or driving people with epilepsy. Univariate and multivariate logistic regression analyses were used to determine the factors associated with attitudes toward marrying, employing, or driving people with epilepsy.

RESULTS

Majority (33%) of the respondents indicated that epilepsy is caused by possession of evil spirits or witchcraft. More than 60% of the respondents correctly identified all signs and symptoms presented in the survey. Almost half (45%) of the respondents selected orthodox/medical treatment as the treatment for epilepsy. The odds of marrying PWE among Akans and Ewe/Ga Adangbe were 90% [adjusted Odds ratio (aOR) = 0.10, 95% CI: 0.01-0.67] and 84% lower [aOR = 0.16, 95% CI: 0.04-0.62] compared to odds of marrying PWE among Northerners, respectively. Compared to respondents with no formal education, the odds of employing PWE were 88% lower [aOR = 0.12, 95% CI: 0.03-0.40] among those with tertiary education. In addition, the odds of driving a person with an epileptic attack among Muslims/Traditionalists were 81% lower [aOR = 0.19, 95% CI: 0.05-0.68] than Christians. Respondents between 18 and 30 years old had more than 5 times higher odds of driving a person with an epileptic attack [aOR 5.28, 95% CI: 1.15-24.84] compared to respondents above 30 years.

CONCLUSIONS

Individuals in Asokore Mampong have less knowledge about the risk factors and treatment of epilepsy. Generally, they have negative attitudes toward marrying, employing, and driving PWE. Findings from this study highlight the need to increase education to reduce the stigma associated with epilepsy. We recommend that a massive educational campaign should be organized by the Ghana Health Service to address deficiencies in knowledge as well as the negative attitudes toward PWE.

The Korean Society for Neuro-Oncology (KSNO) Guideline for Antiepileptic Drug Usage of Brain Tumor: Version 2021.1

Background

To date, there has been no practical guidelines for the prescription of antiepileptic drugs (AEDs) in brain tumor patients in Korea. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, had begun preparing guidelines for AED usage in brain tumors since 2019.

Methods

The Working Group was composed of 27 multidisciplinary medical experts in Korea. References were identified through searches of PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL using specific and sensitive keywords as well as combinations of the keywords.

Results

The core contents are as follows. Prophylactic AED administration is not recommended in newly diagnosed brain tumor patients without previous seizure history. When AEDs are administered during peri/postoperative period, it may be tapered off according to the following recommendations. In seizure-naïve patients with no postoperative seizure, it is recommended to stop or reduce AED 1 week after surgery. In seizure-naïve patients with one early postoperative seizure (<1 week after surgery), it is advisable to maintain AED for at least 3 months before tapering. In seizure-naïve patients with ≥2 postoperative seizures or in patients with preoperative seizure history, it is recommended to maintain AEDs for more than 1 year. The possibility of drug interactions should be considered when selecting AEDs in brain tumor patients. Driving can be allowed in brain tumor patients when proven to be seizure-free for more than 1 year.

Conclusion

The KSNO suggests prescribing AEDs in patients with brain tumor based on the current guideline. This guideline will contribute to spreading evidence-based prescription of AEDs in brain tumor patients in Korea.

Driving a motor vehicle and psychogenic nonepileptic seizures: ILAE Report by the Task Force on Psychogenic Nonepileptic Seizures

OBJECTIVES

This International League Against Epilepsy (ILAE) Report: (a) summarizes the literature about "driving and psychogenic nonepileptic seizures (PNES)"; (b) presents the views of international experts; and (c) proposes an approach to assessing the ability of persons with PNES (PwPNES) to drive.

METHODS

Phase 1: Systematic literature review. Phase 2: Collection of international expert opinion using SurveyMonkey®. Experts included the members of the ILAE PNES Task Force and individuals with relevant publications since 2000. Phase 3: Joint analysis of the findings and refinement of conclusions by all participants using email. As an ILAE Report, the resulting text was reviewed by the Psychiatry Commission, the ILAE Task Force on Driving Guidelines, and Executive Committee.

RESULTS

Eight studies identified by the systematic review process failed to provide a firm evidence base for PNES-related driving regulations, but suggest that most health professionals think restrictions are appropriate. Twenty-six experts responded to the survey. Most held the view that decisions about driving privileges should consider individual patient and PNES characteristics and take account of whether permits are sought for private or commercial driving. Most felt that those with active PNES should not be allowed to drive unless certain criteria were met and that PNES should be thought of as "active" if the last psychogenic seizure had occurred within 6 months.

SIGNIFICANCE

Recommendations on whether PwPNES can drive should be made at the individual patient level. Until future research has determined the risk of accidents in PwPNES a proposed algorithm may guide decisions about driving advice.

Seizures in patients with cancer

Seizures are common in patients with cancer and either result from brain lesions, paraneoplastic syndromes, and complications of cancer treatment or are provoked by systemic illness (metabolic derangements, infections). Evaluation should include a tailored history, neurologic examination, laboratory studies, neuroimaging, and electroencephalogram. In unprovoked seizures, antiepileptic drug (AED) treatment is required, and a nonenzyme-inducing AED is preferred. Treatment of the underlying cancer with surgery, chemotherapy, and radiation therapy also can help reduce seizures. Benzodiazepines are useful in the treatment of both provoked seizures and breakthrough epileptic seizures and as first-line treatment for status epilepticus. Counseling for safety is an important component in the care of a patient with cancer who has seizures. Good seizure management can be challenging but significantly improves the quality of life during all phases of care, including end-of-life care.

Neurologists' attitudes toward driving among persons with epilepsy in China: A pilot electronic survey

PURPOSE AND METHODS

Persons with epilepsy (PWE) remain completely and permanently prohibited from driving in China currently. Previous studies have shown that a considerable proportion of PWE with uncontrolled seizures in China continue to drive motor vehicles. Discrepancy between Chinese policy and driving practices for PWE is potentially concerning. We conducted a preliminary online electronic questionnaire (e-questionnaire) survey among neurologists in China aiming to explore neurologists' attitudes toward the issue of driving among PWE.

RESULTS

A total of 358 neurologists completed the e-questionnaire with a response rate of 75.8%. 50.3% of neurologists stated that they knew the driving restriction law in China. With respect to reporting of cases to relevant driving authorities, 82.4% of neurologists never directly report PWE, and 90.8% consider that it is PWE's responsibility to report themselves. 87.4% of physicians surveyed indicated that the lack of clearly-articulated guidelines is a major impediment to their routine discussions of driving fitness for PWE. Subgroup analysis indicated that 76.2% of epileptologists were of the opinion that persons with well-controlled epilepsy should be allowed to drive versus 56.2% of general neurologists (P < 0.05).

CONCLUSION

Currently, neurologists in China have a low awareness of the legal driving restriction for PWE and have highly varying practices with respect to counseling PWE about driving. According to our preliminary results, a clearly-articulated published national document for medical fitness for driving in China is necessary in order to standardize physicians' practices.

Driving status of patients with generalized spike-wave on EEG but no clinical seizures

Generalized spike-wave discharges (SWDs) are the hallmark of generalized epilepsy on the electroencephalogram (EEG). In clinically obvious cases, generalized SWDs produce myoclonic, atonic/tonic, or absence seizures with brief episodes of staring and behavioral unresponsiveness. However, some generalized SWDs have no obvious behavioral effects. A serious challenge arises when patients with no clinical seizures request driving privileges and licensure, yet their EEG shows generalized SWD. Specialized behavioral testing has demonstrated prolonged reaction times or missed responses during SWD, which may present a driving hazard even when patients or family members do not notice any deficits. On the other hand, some SWDs are truly asymptomatic in which case driving privileges should not be restricted. Clinicians often decide on driving privileges based on SWD duration or other EEG features. However, there are currently no empirically-validated guidelines for distinguishing generalized SWDs that are "safe" versus "unsafe" for driving. Here, we review the clinical presentation of generalized SWD and recent work investigating mechanisms of behavioral impairment during SWD with implications for driving safety. As a future approach, computational analysis of large sets of EEG data during simulated driving utilizing machine learning could lead to powerful methods to classify generalized SWD as safe vs. unsafe. This may ultimately provide more objective EEG criteria to guide decisions on driving safety in people with epilepsy.

Noncompliance of patients with driving restrictions due to uncontrolled epilepsy

Epilepsies are a common and chronic neurological disorder characterized by sustained risk of recurrent seizures. Because of paroxysmal and often unpredictable occurrence of seizures, patients with uncontrolled epilepsy are subject to disease-specific restrictions in daily life, such as their career choice or specific work limitations. According to German law and many other European and international guidelines, driving is strictly prohibited in patients with uncontrolled epilepsy so as to increase active and passive safety in public road traffic. Nevertheless, a significant percentage of patients probably do not comply with these legal restrictions and drive on a regular basis. For this study, we analyzed a representative German cohort with 302 patients (mean age: 45.0 years ± 16.4; 48% male) with established epilepsy to identify the number of patients driving without permission. Overall, 58.6% (n = 177) of patients had a driving license, 71.1% (n = 69/97) of patients were in seizure remission, and 52.7% (n = 108/205) of patients had uncontrolled epilepsy. Among patients in seizure remission, 54.6% (n = 53/97) reported regular driving while, among patients with uncontrolled epilepsy, 15.1% (n = 31/205) reported driving on a regular basis. No patient in the cohort stated driving without a valid license. Permanent employment, freelance work, the absence of a relevant disability, and living alone were identified as significant risk factors, which underlines the already existing evidence for the importance of a possible restricted access to the labor market as motive for disregarding legal driving restrictions. In our opinion, specialized and generally available social counseling with a special focus on vocational and career guidance is urgently needed to improve compliance with epilepsy-caused driving restrictions and the underlying reasons for violating these rules. In addition, more effort has to be spent on improving diagnostics and treatment of epilepsy to reduce the number of patients with uncontrolled seizures. Comprehensive introduction of self-driving vehicles may also help to improve mobility of patients with refractory epilepsy.
