Mindfulness-based therapy for drug-resistant epilepsy

Proceedings of the 2022 "Lifestyle Intervention for Epilepsy (LIFE)" symposium hosted by Cleveland Clinic

Lifestyle interventions are strategies used to self-manage medical conditions, such as epilepsy, and often complement traditional pharmacologic and surgical therapies. The need for integrating evidence-based lifestyle interventions into mainstream medicine for the treatment of epilepsy is evident given that despite the availability of a multitude of treatments with medications and surgical techniques, a significant proportion of patients have refractory seizures, and even those who are seizure-free report significant adverse effects with current treatments. Although the evidence base for complementary medicine is less robust than it is for traditional forms of medicine, the evidence to date suggests that several forms of complementary medicine including yoga, mindfulness meditation, cognitive behavioral therapy, diet and nutrition, exercise and memory rehabilitation, and music therapy may have important roles as adjuncts in the treatment armamentarium for epilepsy. These topics were discussed by a diverse group of medical providers and scientists at the "Lifestyle Intervention for Epilepsy (LIFE)" symposium hosted by Cleveland Clinic. PLAIN LANGUAGE SUMMARY: There are many people with epilepsy who continue to have seizures even though they are being treated with medication or brain surgery. Even after seizures stop, some may experience medication side effects. There is research to suggest that certain lifestyle changes, such as yoga, mindfulness, exercise, music therapy, and adjustments to diet, could help people with epilepsy, when used along with routine treatment. Experts discussed the latest research at the "Lifestyle Intervention for Epilepsy (LIFE)" symposium hosted by Cleveland Clinic.

The effect of 20-minute mindful breathing exercise on psychological well-being in epilepsy: A pilot randomized controlled trial

INTRODUCTION

Depression and anxiety are prevalent in epilepsy patients, but psychiatric or psychological services may not be accessible to all patients. This study aimed to determine the effectiveness of the 20-minute mindful breathing on the psychological well-being of PWE using an instructional video.

METHOD

This was a pilot, assessor-blinded, randomized controlled trial. The intervention group received a guided video and was briefed to perform the exercise twice a week for two weeks while the waitlist control group only received the video upon completion of the study. The subjects were assessed at three-time points (T0: Baseline, T1: 2 weeks after the intervention, T2: 4 weeks after intervention), using the Neurological Disorders Depression Index (NDDI-E), General Anxiety Disorder (GAD-7), Quality of Life in Epilepsy Inventory (QOLIE-31) and Mindfulness Attention Awareness Scale (MAAS).

RESULTS

Twenty patients were recruited, with 10 in the intervention and waitlist-control groups. Compared with the waitlist-control group, participants in the intervention group showed significant improvement in NDDI-E at T1 (p = 0.022) but not at T2 (p = 0.056) and greater improvement in GAD-7 at T1 and T2 but not statistically significant. The QOLIE-31 overall score in the intervention group has significantly improved at T1 (p = 0.036) and T2 (p = 0.031) compared to the waitlist-control group. For MAAS, the intervention group also had an increased score at T2 (p = 0.025).

CONCLUSION

The 20-minute mindfulness breathing exercise has an immediate effect in improving depression and quality of life among people with epilepsy.

EEG changes induced by meditative practices: State and trait effects in healthy subjects and in patients with epilepsy

The effect of meditation on brain activity has been the topic of many studies in healthy subjects and in patients suffering from chronic diseases. These effects are either explored during meditation practice (state effects) or as a longer-term result of meditation training during the resting-state (trait). The topic of this article is to first review these findings by focusing on electroencephalography (EEG) changes in healthy subjects with or without experience in meditation. Modifications in EEG baseline rhythms, functional connectivity and advanced nonlinear parameters are discussed in regard to feasibility in clinical applications. Secondly, we provide a state-of-the-art of studies that proposed meditative practices as a complementary therapy in patients with epilepsy, in whom anxiety and depressive symptoms are prevalent. In these studies, the effects of standardized meditation programs including elements of traditional meditation practices such as mindfulness, loving-kindness and compassion are explored both at the level of psychological functioning and on the occurrence of seizures. Lastly, preliminary results are given regarding our ongoing study, the aim of which is to quantify the effects of a mindfulness self-compassion (MSC) practice on interictal and ictal epileptic activity. Feasibility, difficulties, and prospects of this study are discussed.

Effectiveness of Yoga Intervention in Reducing Felt Stigma in Adults With Epilepsy: A Randomized Controlled Trial

BACKGROUND AND OBJECTIVES

Persons with epilepsy are afflicted with comorbidities such as stigma, anxiety, and depression which have a significant impact on their quality of life. These comorbidities remain largely unaddressed in resource-limited countries. This randomized controlled trial (RCT) aimed to investigate whether yoga and psychoeducation were effective in reducing felt stigma (primary outcome), neuropsychiatric outcomes, and seizure frequency, as compared with sham yoga and psychoeducation in persons with epilepsy.

METHODS

This was an assessor-blinded, sham yoga-controlled RCT. Patients clinically diagnosed with epilepsy, aged 18-60 years, and scoring higher than the cutoff score for felt stigma as measured by the Kilifi Stigma Scale (KSS) in our population were randomly assigned to receive either yoga therapy plus psychoeducation (intervention) or sham yoga therapy plus psychoeducation (comparator) for a duration of 3 months. The primary outcome was a significant decrease in felt stigma as compared with the comparator arm as measured by the KSS. Primary and secondary outcomes (seizure frequency, quality of life, anxiety, depression, mindfulness, trait rumination, cognitive impairment, emotion regulation) were assessed at baseline, 3 months, and 6 months. Parametric/nonparametric analysis of covariance and the χ2 test were used to compare the 2 arms.

RESULTS

A total of 160 patients were enrolled in the trial. At the end of the follow-up period (6 months), the intervention arm reported significant reduction in felt stigma as compared with the control arm (Cohen's d = 0.23, 95% CI -0.08 to 0.55, p = 0.006). Significantly higher odds of >50% seizure reduction (odds ratio [OR] 4.11, 95% CI 1.34-14.69, p = 0.01) and complete seizure remission (OR 7.4, 95% CI 1.75-55.89, p = 0.005) were also observed in the intervention group. The intervention group showed significant improvement in symptoms of anxiety, cognitive impairment, mindfulness, and quality of life relative to the control group at the end of follow-up period (p < 0.05).

DISCUSSION

Yoga can alleviate the burden of epilepsy and improve the overall quality of life in epilepsy by reducing perceived stigma.

TRIAL REGISTRATION INFORMATION

Clinical Trials Registry of India (CTRI/2017/04/008385).

CLASSIFICATION OF EVIDENCE

This study provides Class I evidence that yoga reduces felt stigma in adult patients with epilepsy.

Stress and Epilepsy: Towards Understanding of Neurobiological Mechanisms for Better Management

Stress has been identified as a major contributor to human disease and is postulated to play a substantial role in epileptogenesis. In a significant proportion of individuals with epilepsy, sensitivity to stressful events contributes to dynamic symptomatic burden, notably seizure occurrence and frequency, and presence and severity of psychiatric comorbidities [anxiety, depression, posttraumatic stress disorder (PTSD)]. Here, we review this complex relationship between stress and epilepsy using clinical data and highlight key neurobiological mechanisms including the hypothalamic-pituitary-adrenal (HPA) axis dysfunction, altered neuroplasticity within limbic system structures, and alterations in neurochemical pathways such as brain-derived neurotrophic factor (BNDF) linking epilepsy and stress. We discuss current clinical management approaches of stress that help optimize seizure control and prevention, as well as psychiatric comorbidities associated with epilepsy. We propose that various shared mechanisms of stress and epilepsy present multiple avenues for the development of new symptomatic and preventative treatments, including disease modifying therapies aimed at reducing epileptogenesis. This would require close collaborations between clinicians and basic scientists to integrate data across multiple scales, from genetics to systems biology, from clinical observations to fundamental mechanistic insights. In future, advances in machine learning approaches and neuromodulation strategies will enable personalized and targeted interventions to manage and ultimately treat stress-related epileptogenesis.

Seizures as a Struggle between Life and Death: An Existential Approach to the Psychosocial Impact of Seizures in Candidates for Epilepsy Surgery

INTRODUCTION

Mental health comorbidities such as depression and anxiety are common in epilepsy, especially among people with pharmacoresistant epilepsy who are candidates for epilepsy surgery. The Psychology Task Force of the International League Against Epilepsy advised that psychological interventions should be integrated into comprehensive epilepsy care.

METHODS

To better understand the psychological impact of epilepsy and epileptic seizures in epilepsy surgery candidates, we analysed interviews with this subgroup of patients using Karl Jaspers' concept of limit situations, which are characterised by a confrontation with the limits and challenges of life. These are especially chance, randomness, and unpredictability, death and finitude of life, struggle and self-assertion, guilt, failure, and falling short of one's aspirations.

RESULTS

In 43 interviews conducted with 15 people with drug-resistant epilepsy who were candidates for epilepsy surgery, we found that these themes are recurrent and have a large psychosocial impact, which can result in depression and anxiety. For some people, epileptic seizures appear to meet the criteria for traumatic events.

CONCLUSION

Understanding epilepsy and seizures as existential challenges complements the neurobiological explanations for psychological comorbidities and can help tailor psychological interventions to the specific needs of people with epilepsy, especially those who are candidates for surgical treatment.

[Alternative methods of therapy for comorbid sleep disorders as a method of choice in adult patients with epilepsy]

OBJECTIVE

Systematization and generalization of data from domestic and foreign literature on alternative methods of treatment of sleep disorders in epilepsy.

MATERIAL AND METHODS

The search for data from domestic and foreign literary sources was carried out in the electronic databases Medline (PubMed), Scopus, Web of Science, eLibrary, CyberLeninka, Google Scholar.

RESULTS

The data of modern randomized trials, meta-analyzes on the effectiveness of various non-traditional methods as a method of choice for epilepsy with comorbid sleep disorders have been analyzed.

CONCLUSIONS

Complementary (alternative) treatments have many advantages over the classical pharmacotherapy of sleep disorders in epilepsy, in the form of non-invasiveness, low incidence of side-effects, ease of use, and lack of a dose-dependent effect. Of course, the targets of most of the above methods are not focused and not very specific, and the sample size is too small to obtain impartial and meaningful clinical conclusions, but this once again emphasizes the urgent need for large-scale clinical trials, which is necessary to develop evidence-based treatments for comorbid sleep disorders in epilepsy.

Third-wave psychotherapies to promote mental health in epilepsy: An updated systematic review

PURPOSE/OBJECTIVE

Research on third-wave cognitive behavioral therapies has burgeoned over the last ten years. However, questions remain about the effectiveness of these therapies for people with epilepsy. This article provides an up-to-date review of the current evidence-base.

METHODS

Following protocol registration (PROSPERO CRD42021269882), two reviewers searched six databases (from inception until 1 March 2022) for mindfulness and acceptance interventions targeted at mental health in adults with epilepsy. The reporting quality of included studies was rated (QualSyst tool) and standardized mean group differences (Hedges' g) with 95% confidence intervals and p values calculated. Results were narratively synthesized based on therapy characteristics and mental health outcome.

RESULTS

Eleven randomized controlled trials, involving 941 adults with chronic epilepsy, were included. All studies were of sound methodological quality. Third-wave therapies were typically delivered in a group format although varied in their face-to-face, telephone, and online learning options. Programs evaluating Acceptance and Commitment Therapy, Mindfulness-Based Cognitive Therapy, or elements of both, outperformed wait-listed controls or usual care, although individual variability in treatment response was evident (g_range = -0.11-2.28).

CONCLUSIONS

Acceptance techniques and mindfulness practice may bring mental health benefits for some people living with epilepsy, but do not have consistent results for everyone. Patient diversity and preferences need to be factored into effective third-wave approaches for this cohort.

Mediating Mindfulness-Based Interventions with Virtual Reality in Non-Clinical Populations: The State-of-the-Art

Mindfulness is one of the most popular psychotherapeutic techniques that help to promote good mental and physical health. Combining mindfulness with immersive virtual reality (VR) has been proven to be especially effective for a wide range of mood disorders for which traditional mindfulness has proven valuable. However, the vast majority of immersive VR-enhanced mindfulness applications have focused on clinical settings, with little evidence on healthy subjects. This narrative review evaluates the real effectiveness of state-of-the-art mindfulness interventions mediated by VR systems in influencing mood and physiological status in non-clinical populations. Only studies with an RCT study design were considered. We conclude that most studies were characterized by one single meditation experience, which seemed sufficient to induce a significant reduction in negative mood states (anxiety, anger, depression, tension) combined with increased mindfulness skills. However, physiological correlates of mindfulness practices have scarcely been investigated. The application of VR-enhanced mindfulness-based interventions in non-clinical populations is in its infancy since most studies have several limitations, such as the poor employment of the RCT study design, the lack of physiological measurements (i.e., heart rate variability), as well as the high heterogeneity in demographical data, technological devices, and VR procedures. We thus concluded that before applying mindfulness interventions mediated by VR in clinical populations, more robust and reliable methodological procedures need to be defined.

The Effect of Mindfulness-based Programs on Cognitive Function in Adults: A Systematic Review and Meta-analysis

Mindfulness-based programs (MBPs) are increasingly utilized to improve mental health. Interest in the putative effects of MBPs on cognitive function is also growing. This is the first meta-analysis of objective cognitive outcomes across multiple domains from randomized MBP studies of adults. Seven databases were systematically searched to January 2020. Fifty-six unique studies (n = 2,931) were included, of which 45 (n = 2,238) were synthesized using robust variance estimation meta-analysis. Meta-regression and subgroup analyses evaluated moderators. Pooling data across cognitive domains, the summary effect size for all studies favored MBPs over comparators and was small in magnitude (g = 0.15; [0.05, 0.24]). Across subgroup analyses of individual cognitive domains/subdomains, MBPs outperformed comparators for executive function (g = 0.15; [0.02, 0.27]) and working memory outcomes (g = 0.23; [0.11, 0.36]) only. Subgroup analyses identified significant effects for studies of non-clinical samples, as well as for adults aged over 60. Across all studies, MBPs outperformed inactive, but not active comparators. Limitations include the primarily unclear within-study risk of bias (only a minority of studies were considered low risk), and that statistical constraints rendered some p-values unreliable. Together, results partially corroborate the hypothesized link between mindfulness practices and cognitive performance. This review was registered with PROSPERO [CRD42018100904].

Divergent Anatomical Correlates and Functional Network Connectivity Patterns in Temporal Lobe Epilepsy with and Without Depression

Epilepsy and depression were proposed to facilitate each other reciprocally through common neurobiological anomalies, especially the prefrontal-limbic-subcortical abnormalities. Yet neuroimaging patterns of higher-order cognitive networks and neuroanatomical correlates were rarely compared in temporal lobe epilepsy patients with (TLE-D) and without depression (TLE-N). We collected T1-weighted structural and resting-state functional MRI data from 20 TLE-D, 31 TLE-N and 20 healthy controls (HCs) and performed analyses including hippocampal volume (HCV), cortical thickness, gray matter volume (GMV) and whole-brain functional network connectivity (FNC) across three groups. Imaging differences were related to clinical and psychological measurements. TLE-D demonstrated disrupted functional role of subcortical (SUB) and higher-order cognitive networks compared to TLE-N and HCs. In TLE-D, GMV in the right supplementary motor area (SMA) and FNC between the dorsal attention (DAN) and SUB were attenuated compared to TLE-N and HCs, FNC between SUB and the visual network (VIS) decreased compared to HCs. GMV in the right SMA was negatively correlated with depression severity and some symptoms. Combined, explicit emotion regulation may be impaired in TLE-D. Meanwhile, compared to HCs, TLE-N showed smaller HCVs, TLE-D and TLE-N showed smaller GMV in the medial orbital frontal gyrus and right hippocampus and hippocampal gyrus, possibly implying predisposition of epileptic activities to co-morbid depression. Our findings suggest distinct anatomical and FNC patterns in TLE-D and TLE-N. More than prefrontal-limbic-subcortical anomalies, disrupted higher-order cognitive network may contribute to depression in TLE, providing new potential treatment targets for depression and calling attention to relation between cognitive dysfunction and co-morbid depression.

Mindfulness-based intervention to promote psychological wellbeing in people with epilepsy: A randomized controlled trial

BACKGROUND

We investigated the efficacy of mindfulness-based intervention (MBI) in promoting psychological wellbeing in people with epilepsy (PWE) using an assessor-blinded randomized controlled design.

METHODS

A total of 28 PWE were randomly assigned to either intervention (n = 14 cases) or control group (n = 14 controls). The intervention group received a six 2.5-hour weekly MBI, while the control group did not receive any intervention. They were assessed at three timepoints (T0: before intervention, T1: immediately after intervention, and T2: 6 weeks after intervention). Repeated measures of analyses of variance (RM-ANOVAs) were used for inter-group comparisons to determine intervention effect from baseline -to T1 and -to T2 for all outcome measures. The individual changes were calculated using the reliable change index (RCI). Key outcomes included depression (BDI-II), anxiety (BAI), epilepsy-related quality of life (QOLIE-31), satisfaction with life (SWLS), and level of mindfulness (MAAS).

RESULTS

Participants who participated in the MBI showed significant reduction in BDI-II (p = 0.001), significant increases in MAAS (p = 0.027) and QOLIE-31 (p = 0.001) at T1 when compared with the control group. However, BAI and SWLS were not significant. The trend was similar at 6-week follow-up, all outcome measures of MBI remained significant (p < 0.05) except for BAI and SWLS. Beyond the 6-week intervention, RCI analysis showed a significant improvement in levels of mindfulness (45.45% vs. 21.43%, p = 0.009), depression (45.45% vs. 0.00%, p = 0.016), quality of life (45.45% vs. 14.29%, p = 0.017) with MBI, as compared to the no-intervention phase.

CONCLUSION

Mindfulness-based intervention is effective in reducing psychological distress and improving the quality of life in PWE.

From Precision Metapharmacology to Patient Empowerment: Delivery of Self-Care Practices for Epilepsy, Pain, Depression and Cancer Using Digital Health Technologies

To improve long-term outcomes of therapies for chronic diseases, health promotion and lifestyle modifications are the most promising and sustainable strategies. In addition, advances in digital technologies provide new opportunities to address limitations of drug-based treatments, such as medication non-adherence, adverse effects, toxicity, drug resistance, drug shortages, affordability, and accessibility. Pharmaceutical drugs and biologics can be combined with digital health technologies, including mobile medical apps (digital therapeutics), which offer additional clinical benefits and cost-effectiveness. Promises of drug+digital combination therapies are recognized by pharmaceutical and digital health companies, opening opportunities for integrating pharmacotherapies with non-pharmacological interventions (metapharmacology). Herein we present unique features of digital health technologies which can deliver personalized self-care modalities such as breathing exercises, mindfulness meditation, yoga, physical activity, adequate sleep, listening to preferred music, forgiveness and gratitude. Clinical studies reveal how aforementioned complimentary practices may support treatments of epilepsy, chronic pain, depression, cancer, and other chronic diseases. This article also describes how digital therapies delivering “medicinal” self-care and other non-pharmacological interventions can also be personalized by accounting for: 1) genetic risks for comorbidities, 2) adverse childhood experiences, 3) increased risks for viral infections such as seasonal influenza, or COVID-19, and 4) just-in-time stressful and traumatic circumstances. Development and implementation of personalized pharmacological-behavioral combination therapies (precision metapharmacology) require aligning priorities of key stakeholders including patients, research communities, healthcare industry, regulatory and funding agencies. In conclusion, digital technologies enable integration of pharmacotherapies with self-care, lifestyle interventions and patient empowerment, while concurrently advancing patient-centered care, integrative medicine and digital health ecosystems.

Recent Advances in Neuroimaging of Epilepsy

Human neuroimaging has had a major impact on the biological understanding of epilepsy and the relationship between pathophysiology, seizure management, and outcomes. This review highlights notable recent advancements in hardware, sequences, methods, analyses, and applications of human neuroimaging techniques utilized to assess epilepsy. These structural, functional, and metabolic assessments include magnetic resonance imaging (MRI), positron emission tomography (PET), and magnetoencephalography (MEG). Advancements that highlight non-invasive neuroimaging techniques used to study the whole brain are emphasized due to the advantages these provide in clinical and research applications. Thus, topics range across presurgical evaluations, understanding of epilepsy as a network disorder, and the interactions between epilepsy and comorbidities. New techniques and approaches are discussed which are expected to emerge into the mainstream within the next decade and impact our understanding of epilepsies. Further, an increasing breadth of investigations includes the interplay between epilepsy, mental health comorbidities, and aberrant brain networks. In the final section of this review, we focus on neuroimaging studies that assess bidirectional relationships between mental health comorbidities and epilepsy as a model for better understanding of the commonalities between both conditions.

Multipronged Attack of Stem Cell Therapy in Treating the Neurological and Neuropsychiatric Symptoms of Epilepsy

Epilepsy stands as a life-threatening disease that is characterized by unprovoked seizures. However, an important characteristic of epilepsy that needs to be examined is the neuropsychiatric aspect. Epileptic patients endure aggression, depression, and other psychiatric illnesses. Therapies for epilepsy can be divided into two categories: antiepileptic medications and surgical resection. Antiepileptic drugs are used to attenuate heightened neuronal firing and to lessen seizure frequency. Alternatively, surgery can also be conducted to physically cut out the area of the brain that is assumed to be the root cause for the anomalous firing that triggers seizures. While both treatments serve as viable approaches that aim to regulate seizures and ameliorate the neurological detriments spurred by epilepsy, they do not serve to directly counteract epilepsy's neuropsychiatric traits. To address this concern, a potential new treatment involves the use of stem cells. Stem cell therapy has been employed in experimental models of neurological maladies, such as Parkinson's disease, and neuropsychiatric illnesses like depression. Cell-based treatments for epilepsy utilizing stem cells such as neural stem cells (NSCs), mesenchymal stem cells (MSCs), and interneuron grafts have been explored in preclinical and clinical settings, highlighting both the acute and chronic stages of epilepsy. However, it is difficult to create an animal model to capitalize on all the components of epilepsy due to the challenges in delineating the neuropsychiatric aspect. Therefore, further preclinical investigation into the safety and efficacy of stem cell therapy in addressing both the neurological and the neuropsychiatric components of epilepsy is warranted in order to optimize cell dosage, delivery, and timing of cell transplantation.

Development and preliminary evaluation of the psychometric properties of the psychological flexibility in epilepsy questionnaire (PFEQ)

The present study describes the development and preliminary psychometric evaluation of the Psychological Flexibility in Epilepsy Questionnaire (PFEQ), which was developed to measure the construct referred to as Psychological Flexibility (PF) in epilepsy. Results from 81 participants with epilepsy support a one-factor solution, consisting of 12 items, indicating a satisfactory structure and reliability with an alpha coefficient of 0.92. Criterion validity of the instrument was supported by moderate correlations with outcomes predicting quality of life, PF in the general population, depressive symptoms, and anxiety symptoms. Number of seizures in the past three and 12 months was positively correlated with scores on the PFEQ. These findings are consistent with the instrument's underlying theory. Further development and investigation of the PFEQ is recommended, as the preliminary results of the questionnaire suggest that the scale has the potential to be a valuable contribution to the future exploration of the role of PF in epilepsy.

Clinical Management of Drug Resistant Epilepsy: A Review on Current Strategies

Drug resistant epilepsy (DRE) is defined as the persistence of seizures despite at least two syndrome-adapted antiseizure drugs (ASD) used at efficacious daily dose. Despite the increasing number of available ASD, about a third of patients with epilepsy still suffer from drug resistance. Several factors are associated with the risk of evolution to DRE in patients with newly diagnosed epilepsy, including epilepsy onset in the infancy, intellectual disability, symptomatic epilepsy and abnormal neurological exam. Pharmacological management often consists in ASD polytherapy. However, because quality of life is driven by several factors in patients with DRE, including the tolerability of the treatment, ASD management should try to optimize efficacy while anticipating the risks of drug-related adverse events. All patients with DRE should be evaluated at least once in a tertiary epilepsy center, especially to discuss eligibility for non-pharmacological therapies. This is of paramount importance in patients with drug resistant focal epilepsy in whom epilepsy surgery can result in long-term seizure freedom. Vagus nerve stimulation, deep brain stimulation or cortical stimulation can also improve seizure control. Lastly, considering the effect of DRE on psychologic status and social integration, comprehensive care adaptations are always needed in order to improve patients' quality of life.

The Management and Alternative Therapies for Comorbid Sleep Disorders in Epilepsy

BACKGROUND

There is a complex and interactive relationship between sleep and epilepsy. Sleep disorders are common in patients with epilepsy, and methods for managing sleep disorders in patients with epilepsy are limited.

OBJECTIVE

This review addresses the relationship among sleep, sleep disorders, and epilepsy, focusing on the management of sleep disorders in epilepsy, including some complementary and alternative therapies.

METHODS

The terms related to "sleep" and "epilepsy" were searched in "Pubmed" and "Cochrane Library".

RESULTS

Sleep stages differently affect both seizures and interictal epileptiform discharges. Seizures disrupt sleep architecture greatly, especially when occurring during sleep in the night. Insomnia and obstructive sleep apnea (OSA) are the most frequent types of comorbid sleep disorders in patients with epilepsy. Pharmacological agents with both anti-convulsant and sedative effects are the priorities for comorbid sleep disorders in epilepsy. Continuous positive airway pressure (CPAP) therapy is the most effective non-pharmacological method to improve OSA and reduce seizures. Complementary and alternative therapies such as Chinese traditional medicine, cognitive behavioral therapy, meditation, yoga, neurofeedback, and acupuncture may have benefits in reducing seizures and improving sleep quality simultaneously by alleviating stress and seizure triggers; however, evidence- based therapies are still deficient.

CONCLUSION

Management of sleep disorders in patients with epilepsy is challenging. Large-scale randomized controlled clinical trials are in demand to guide the treatments in the future.

Association of Levels of Specialized Care With Risk of Premature Mortality in Patients With Epilepsy

Importance

Patients with epilepsy are at an elevated risk of premature mortality. Interventions to reduce this risk are crucial.

Objective

To determine if the level of care (non-neurologist, neurologist, or comprehensive epilepsy program) is negatively associated with the risk of premature mortality.

Design, Setting, and Participants

In this retrospective open cohort study, all adult patients 18 years or older who met the administrative case definition for incident epilepsy in linked databases (Alberta Health Services administrative health data and the Comprehensive Calgary Epilepsy Programme Registry [CEP]) inclusive of the years 2002 to 2016 were followed up until death or loss to follow-up. The final analyses were performed on May 1, 2019.

Exposures

Evaluation by a non-neurologist, neurologist, or epileptologist.

Main Outcomes and Measures

The outcome was all-cause mortality. We used extended Cox models treating exposure to a neurologist or the CEP as time-varying covariates. Age, sex, socioeconomic deprivation, disease severity, and comorbid burden at index date were modeled as fixed-time coefficients.

Results

A total 23 653 incident cases were identified (annual incidence of 89 per 100 000); the mean age (SD) at index date was 50.8 (19.1) years and 12 158 (50.3%) were women. A total of 14 099 (60%) were not exposed to specialist neurological care, 9554 (40%) received care by a neurologist, and 2054 (9%) received care in the CEP. In total, 4098 deaths (71%) occurred in the nonspecialist setting, 1481 (26%) for those seen by a neurologist, and 176 (3%) for those receiving CEP care. The standardized mortality rate was 7.2% for the entire cohort, 9.4% for those receiving nonspecialist care, 5.6% for those seen by a neurologist, and 2.8% for those seen in the CEP. The hazard ratio (HR) of mortality was lower in those receiving neurologist (HR, 0.85; 95% CI, 0.77-0.93) and CEP (HR, 0.49; 95% CI, 0.38-0.62) care. In multivariable modeling, specialist care, the age at index, and disease severity were retained in the final model of the association between specialist care and mortality.

Conclusions and Relevance

Exposure to specialist care is associated with incremental reductions in the hazard of premature mortality. Those referred to a comprehensive epilepsy program received the greatest benefit.

A live-online mindfulness-based intervention for children living with epilepsy and their families: protocol for a randomized controlled trial of Making Mindfulness Matter©

BACKGROUND

Epilepsy extends far beyond seizures; up to 80% of children with epilepsy (CWE) may have comorbid cognitive or mental health problems, and up to 50% of parents of CWE are at risk for major depression. Past research has also shown that family environment has a greater influence on children's and parents' health-related quality of life (HRQOL) and mental health than epilepsy-related factors. There is a pressing need for low-cost, innovative interventions to improve HRQOL and mental health for CWE and their parents. The aim of this randomized controlled trial (RCT) is to evaluate whether an interactive online mindfulness-based intervention program, Making Mindfulness Matter (M3), can be feasibly implemented and whether it positively affects CWE's and parents' HRQOL and mental health (specifically, stress, behavioral, depressive, and anxiety symptoms).

METHODS

This parallel RCT was planned to recruit 100 child-parent dyads to be randomized 1:1 to the 8-week intervention or waitlist control and followed over 20 weeks. The intervention, M3, will be delivered online and separately to parents and children (ages 4-10 years) in groups of 4-8 by non-clinician staff of a local community epilepsy agency. The intervention incorporates mindful awareness, social-emotional learning skills, and positive psychology. It is modeled after the validated school-based MindUP program and adapted for provision online and to include a parent component.

DISCUSSION

This RCT will determine whether this online mindfulness-based intervention is feasible and effective for CWE and their parents. The proposed intervention may be an ideal vector to significantly improve HRQOL and mental health for CWE and their parents given its low cost and implementation by community epilepsy agencies.

Psychological treatments for people with epilepsy

BACKGROUND

Given the significant impact epilepsy may have on the health-related quality of life (HRQOL) of individuals with epilepsy and their families, there is increasing clinical interest in evidence-based psychological treatments, aimed at enhancing psychological and seizure-related outcomes for this group. This is an updated version of the original Cochrane Review published in Issue 10, 2017.

OBJECTIVES

To assess the impact of psychological treatments for people with epilepsy on HRQOL outcomes.

SEARCH METHODS

For this update, we searched the following databases on 12 August 2019, without language restrictions: Cochrane Register of Studies (CRS Web), which includes randomized or quasi-randomized controlled trials from the Specialized Registers of Cochrane Review Groups including Epilepsy, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid, 1946 to 09 August 2019), and PsycINFO (EBSCOhost, 1887 onwards), and from PubMed, Embase, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (ICTRP). We screened the references from included studies and relevant reviews, and contacted researchers in the field for unpublished studies.

SELECTION CRITERIA

We considered randomized controlled trials (RCTs) and quasi-RCTs for this review. HRQOL was the main outcome. For the operational definition of 'psychological treatments', we included a broad range of skills-based psychological treatments and education-only interventions designed to improve HRQOL, seizure frequency and severity, as well as psychiatric and behavioral health comorbidities for adults and children with epilepsy. These psychological treatments were compared to treatment as usual (TAU), an active control group (such as social support group), or antidepressant pharmacotherapy.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included 36 completed RCTs, with a total of 3526 participants. Of these studies, 27 investigated skills-based psychological interventions. The remaining nine studies were education-only interventions. Six studies investigated interventions for children and adolescents, three studies investigated interventions for adolescents and adults, and the remaining studies investigated interventions for adults. Based on satisfactory clinical and methodological homogeneity, we pooled data from 11 studies (643 participants) that used the Quality of Life in Epilepsy-31 (QOLIE-31) or other QOLIE inventories (such as QOLIE-89 or QOLIE-31-P) convertible to QOLIE-31. We found significant mean changes for the QOLIE-31 total score and six subscales (emotional well-being, energy and fatigue, overall QoL, seizure worry, medication effects, and cognitive functioning). The mean changes in the QOLIE-31 total score (mean improvement of 5.23 points, 95% CI 3.02 to 7.44; P < 0.001), and the overall QoL score (mean improvement of 5.95 points, 95% CI 3.05 to 8.85; P < 0.001) exceeded the threshold of minimally important change (MIC: total score: 4.73 points; QoL score: 5.22 points), indicating a clinically meaningful postintervention improvement in HRQOL. We downgraded the certainty of the evidence provided by the meta-analysis due to serious risks of bias in some of the included studies. Consequently, these results provided moderate-certainty evidence that psychological treatments for adults with epilepsy may enhance overall HRQOL.

AUTHORS' CONCLUSIONS

Implications for practice: Skills-based psychological interventions improve HRQOL in adults and adolescents with epilepsy. Adjunctive use of skills-based psychological treatments for adults and adolescents with epilepsy may provide additional benefits in HRQOL when these are incorporated into patient-centered management. We judge the evidence to be of moderate certainty.

IMPLICATIONS FOR RESEARCH

Investigators should strictly adhere to the CONSORT guidelines to improve the quality of reporting on their interventions. A thorough description of intervention protocols is necessary to ensure reproducibility. When examining the effectiveness of psychological treatments for people with epilepsy, the use of standardized HRQOL inventories, such as the Quality of Life in Epilepsy Inventories (QOLIE-31, QOLIE-31-P, and QOLIE-89) would increase comparability. Unfortunately, there is a critical gap in pediatric RCTs and RCTs including people with epilepsy and intellectual disabilities. Finally, in order to increase the overall quality of RCT study designs, adequate randomization with allocation concealment and blinded outcome assessment should be pursued. As attrition is often high in research that requires active participation, an intention-to-treat analysis should be carried out. Treatment fidelity and treatment competence should also be assessed. These important dimensions, which are related to 'Risk of bias' assessment, should always be reported.

Psychosocial profiles and their predictors in epilepsy using patient-reported outcomes and machine learning

OBJECTIVE

To apply unsupervised machine learning to patient-reported outcomes to identify clusters of epilepsy patients exhibiting unique psychosocial characteristics.

METHODS

Consecutive outpatients seen at the Calgary Comprehensive Epilepsy Program outpatient clinics with complete patient-reported outcome measures on quality of life, health state valuation, depression, and epilepsy severity and disability were studied. Data were acquired at each patient's first clinic visit. We used k-means++ to segregate the population into three unique clusters. We then used multinomial regression to determine factors that were statistically associated with patient assignment to each cluster.

RESULTS

We identified 462 consecutive patients with complete patient-reported outcome measure (PROM) data. Post hoc analysis of each cluster revealed one reporting elevated measures of psychosocial health on all five PROMs ("high psychosocial health" cluster), one with intermediate measures ("intermediate" cluster), and one with poor overall measures of psychosocial health ("poor psychosocial health" cluster). Failing to achieve at least 1 year of seizure freedom (relative risk [RR] = 4.34, 95% confidence interval [CI] = 2.13-9.09) predicted placement in the "intermediate" cluster relative to the "high" cluster. In addition, failing to achieve seizure freedom, social determinants of health, including the need for partially or completely subsidized income support (RR = 6.10, 95% CI = 2.79-13.31, P < .001) and inability to drive (RR = 4.03, 95% CI = 1.6-10.00, P = .003), and a history of a psychiatric disorder (RR = 3.16, 95% CI = 1.46-6.85, P = .003) were associated with the "poor" cluster relative to the "high" cluster.

SIGNIFICANCE

Seizure-related factors appear to drive placement in the "intermediate" cluster, with social determinants driving placement in the "poor" cluster, suggesting a threshold effect. Precision intervention based on cluster assignment, with an initial emphasis on improving social support and careful titration of medications for those reporting the worst psychosocial health, could help optimize health for patients with epilepsy.

Depression, Mindfulness, and Psilocybin: Possible Complementary Effects of Mindfulness Meditation and Psilocybin in the Treatment of Depression. A Review

Depression is a major public health problem that affects approximately 4.4% of the global population. Since conventional pharmacotherapies and psychotherapies are only partially effective, as demonstrated by the number of patients failing to achieve remission, alternative treatments are needed. Mindfulness meditation (MM) and psilocybin represent two promising novel treatments that might even have complementary therapeutic effects when combined. Since the current literature is limited to theoretical and empirical underpinnings of either treatment alone, the present review aimed to identify possible complementary effects that may be relevant to the treatment of depression. To that end, the individual effects of MM and psilocybin, and their underlying working mechanisms, were compared on a non-exhaustive selection of six prominent psychological and biological processes that are well known to show impairments in patients suffering from major depression disorder, that is mood, executive functioning, social skills, neuroplasticity, core neural networks, and neuroendocrine and neuroimmunological levels. Based on predefined search strings used in two online databases (PubMed and Google Scholar) 1129 articles were identified. After screening title and abstract for relevance related to the question, 82 articles were retained and 11 were added after reference list search, resulting in 93 articles included in the review. Findings show that MM and psilocybin exert similar effects on mood, social skills, and neuroplasticity; different effects were found on executive functioning, neural core networks, and neuroendocrine and neuroimmune system markers. Potential mechanisms of MM's effects are enhanced affective self-regulation through mental strategies, optimization of stress reactivity, and structural and functional adjustments of prefrontal and limbic areas; psilocybin's effects might be established via attenuation of cognitive associations through deep personal insights, cognitive disinhibition, and global neural network disintegration. It is suggested that, when used in combination, MM and psilocybin could exert complementary effects by potentiating or prolonging mutual positive effects, for example, MM potentially facilitating psilocybin-induced peak experiences. Future placebo-controlled double-blind randomized trials focusing on psilocybin-assisted mindfulness-based therapy will provide knowledge about whether the proposed combination of therapies maximizes their efficacy in the treatment of depression or depressive symptomatology.

Effect of intensive self-management education on seizure frequency and quality of life in epilepsy patients with prodromes or precipitating factors

PURPOSE

To explore the impact of an intensive self-management education strategy on seizure frequency and quality of life in patients with epileptic seizures with prodromes or precipitating factors. The intensive self-management education included monthly education sessions on prodromes and precipitating factors aiming to help patients to adopt self-management strategies.

METHODS

Adult patients with epilepsy (PWE) able to identify prodromes or precipitating factors of their seizures were randomly assigned to an intensive education group (IEG) (n = 45) or a regular education group(REG) (n = 47). All patients received a single face-to-face self-management education session at the time of enrollment. Both groups of patients received monthly telephone follow-up for 1 year. PWE in the IEG received intensive education during each follow-up call. Primary outcomes were seizure frequency, quality of life(Quality of life in epilepsy-31 inventory scores, QOLIE 31), and drug adherence(Morisky medication adherence scale,MMAS).

RESULTS

At the end of the 1-year follow-up period, seizure frequency in the IEG was significantly lower than at baseline (p < 0.001), but not in the REG(p = 0.085). Quality of life had improved significantly in the IEG (p < 0.001), but not in the REG (p = 0.073). Drug adherence was better in the IEG than in the REG (p = 0.003), and there were fewer accidental injuries in the IEG than the REG (p = 0.031).

CONCLUSIONS

In PWE aware of seizure prodromes or precipitating factors, intensive self-management education may reduce seizure frequency, improve quality of life, increase adherence with antiepileptic medication and reduce accidental injuries caused by seizures.

Anxiety Disorders and Medical Comorbidity: Treatment Implications

Anxiety disorders are debilitating psychological disorders characterized by a wide range of cognitive and somatic symptoms. Anxiety sufferers have a higher lifetime prevalence of various medical problems. Chronic medical conditions furthermore increase the likelihood of psychiatric disorders and overall dysfunction. Lifetime rates of cardiovascular, respiratory, gastrointestinal, and other medical problems are disproportionately high in anxiety and panic/fear sufferers. The heightened comorbidity is not surprising as many symptoms of anxiety and panic/fear mimic symptoms of medical conditions. Panic disorder specifically is strongly linked to medical conditions due to its salient somatic symptoms, such as dyspnea, dizziness, numbness, chest pain, and heart palpitations, all of which can signal danger and deterioration for chronic disease sufferers. This chapter identifies shared correlates of medical illness and anxiety disorders and evidence for misinterpretation of symptoms as medically relevant and offers an analysis of implications for treatment of both types of conditions. We will concentrate on medical conditions with high associations for anxiety and panic by aspects of symptomatology, specifically neurological disorders (fibromyalgia, epilepsy, cerebral palsy), diabetes, gastrointestinal illness (irritable bowel syndrome, gastroesophageal reflux disease), and cardiovascular and respiratory illnesses (asthma).

Behavioral interventions in epilepsy

PURPOSE OF REVIEW

Behavioral intervention describes multiple modalities of treatments which are of increasing interest in epilepsy. This review addresses recent behavioral clinical trials in epilepsy including cognitive behavioral therapy (CBT), mindfulness, progressive muscle relaxation (PMR), and self-management. Results and conclusions from updated Cochrane reviews and the recent International League Against Epilepsy Psychology task force are presented.

RECENT FINDINGS

Two recent large randomized controlled trials (mindfulness and progressive muscle relaxation) reported improved seizure frequency with behavioral treatments. In both studies, participants in both the active and the attentional control arms showed significant seizure reduction, whereas quality of life and stress reduction were better noted in the active arms. Additional behavioral modalities have reported improved seizure control including yoga, bio/neurofeedback, and music therapy.Significant improvements in multiple quality of life, cognitive domains, and medication adherence have been reported from randomized and open label trials of cognitive behavioral therapy, and self-management programs. Multiple promising self-management programs have been recently reported, often utilizing the power of web-based apps, and digitally delivered group therapy. In 2018, the International League Against Epilepsy Psychology task force recommended that 'psychological interventions should be incorporated into comprehensive epilepsy care.'

SUMMARY

Behavioral treatments are successful and likely underutilized in the treatment of epilepsy. Given the challenge of conducting randomized clinical trials of behavioral therapy, much remains to be studied. However, for motivated and interested patients, appropriately chosen behavioral therapies appear to be important adjuncts to standard therapy. The timing is currently optimal to take best advantage of smartphone apps and web-based delivery systems, both for research and therapeutic purposes.

The psychopharmacology of epilepsy

Epilepsy affects 1% of the world's population and is defined as two or more unprovoked seizures. Psychiatric conditions (depression, psychosis, anxiety, and attention deficit hyperactivity disorder (ADHD)) may coexist and are linked to negative seizure outcomes and poorer quality of life. There is an increasing body of evidence to suggest a bidirectional relationship between epilepsy and psychiatric disorders, which may imply shared pathophysiologic mechanisms. Extensive research has examined neurobiologic and neuroanatomic substrates for this association revealing some interesting similarities. Psychiatric disorders in people with epilepsy often go underdiagnosed and undertreated, due to fears of exacerbating psychiatric symptoms or provoking seizures, which may cause delays in optimal management. This chapter covers psychiatric conditions in epilepsy largely focusing on depressive disorders and psychotic disorders. Anxiety and ADHD in association with epilepsy are also discussed. Epidemiology, pathophysiologic mechanisms, and pharmacotherapies used to treat epilepsy and psychiatric disorders are also covered.

Adjustment to hand injury: Cross-sectional survey exploring adjustment in relation to illness perceptions and coping strategies

STUDY DESIGN

Cross-sectional descriptive.

INTRODUCTION

Hand injuries are highly prevalent, and the impact they have on physical, emotional, and functional adjustment is well recognized. Increasingly, adjustment to health conditions including hand injuries is being understood in terms of psychological variables.

PURPOSE OF THE STUDY

To examine the role of illness beliefs and coping strategies in adjustment to hand injury. Adjustment was considered from a complete perspective including quality of life (QOL) and functional ability as well as mood and trauma symptoms.

METHODS

Cross-sectional survey whereby consecutive patients (n = 65) attending the regional plastic surgery service with hand injuries were invited to complete a questionnaire assessing illness perceptions, coping strategies, QOL, hand functioning, depression, and trauma symptoms. Data were analyzed in SPSS (IBM Corporation, Armonk, NY) by correlation and then hierarchical regression analysis.

RESULTS

Illness perceptions and coping strategies were significantly related to the adjustment outcomes (hand functioning, QOL, depression, and trauma symptoms). Specifically, poorer adjustment was associated with more negative illness beliefs (r = 0.31-0.47), greater use of denial (r = 0.24-0.53), and avoidance-based (r = 0.41-0.64) coping strategies.

DISCUSSION

Illness beliefs and coping play an important role in adjustment after hand injury. Adjustment is multifaceted with a need to consider physical and emotional functioning. More optimistic beliefs and adaptive coping styles are associated with improved adjustment.

CONCLUSION

The role of psychological variables in optimizing adjustment is an important consideration for the design of psychological interventions, but because this study was cross sectional and cannot assume directional effects, future longitudinal studies are needed.

Multidisciplinary management improves anxiety, depression, medication adherence, and quality of life among patients with epilepsy in eastern China: A prospective study

OBJECTIVE

The objective of this study was to investigate the effect of a multidisciplinary program on anxiety, depression, medication adherence, and quality of life in patients with epilepsy in eastern China.

METHODS

A cohort of 184 patients with epilepsy from the epilepsy clinic of a tertiary hospital in eastern China completed this program, out of which 92 were randomized into the intervention group and 92 the control group. Patients in both groups received standard antiepileptic drugs (AEDs), while those of the intervention group received an additional 12-month multidisciplinary program developed by a group of the epileptologist, pharmacist, psychiatrist, and epilepsy specialist nurse. Patients were assessed both before and after the 12-month period. The Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and the eight-item Morisky Medication Adherence Scale (MMAS-8) were used to assess the severity of depression, anxiety, and medication adherence, respectively, along with Quality of life in Epilepsy-31 (QOLIE-31) and self-reported seizure frequency for life quality and seizure severity.

RESULTS

The 12-month multidisciplinary program significantly reduced the number of patients with severe depression (p = 0.013) and anxiety (p = 0.002), increased the number of patients with moderate-to-high AED adherence (p = 0.006) and the overall QOLIE-31 score (p < 0.001) in the intervention group. Both groups demonstrated a significant increase in the number of patients with a low seizure frequency after the 12-month period (p < 0.001).

CONCLUSION

The 12-month multidisciplinary program offers an effective management strategy in improving psychiatric comorbidities, medication adherence, and quality of life in patients with epilepsy in eastern China.

Seizure self-prediction in a randomized controlled trial of stress management

OBJECTIVE

Using electronic diaries as part of a randomized controlled trial of stress reduction for epilepsy, we evaluated factors associated with successful seizure self-prediction.

METHODS

Adults with medication-resistant focal epilepsy were recruited from 3 centers and randomized to treatment with progressive muscle relaxation or control focused attention. An 8-week baseline was followed by 12 weeks of double-blind treatment. Twice daily, participants rated the likelihood of a seizure in the next 24 hours on a 5-point scale from very unlikely to almost certain, along with mood, premonitory symptoms, stress ratings, and seizure counts. We analyzed the association of mood, premonitory symptoms, stress, and circadian influences on seizure self-prediction.

RESULTS

Sixty-four participants completed the trial (3,126 seizures). Diary entry adherence was >82%. Participant self-prediction was associated with seizure occurrence at 6, 12, and 24 hours (p < 0.0001). Odds ratio (OR) of seizure prediction increased systematically with participants' prediction of seizure likelihood (p < 0.0001, all levels of prediction and all time intervals). For the 12-hour prediction window, median specificity for seizure prediction was 0.94 and negative predictive value 0.94; median sensitivity was 0.10 and positive predictive value 0.13. A subset of 13 participants (20% of sample) met criteria for good predictors (median OR for seizure prediction 5.25). Mood, stress, premonitory symptoms, seizure time, and randomized group were not associated with seizure occurrence.

CONCLUSION

In this prospective study, participants' prediction of a high probability of seizure was significantly associated with subsequent seizure occurrence within 24 hours. Future studies should focus on understanding factors that drive self-prediction.

What really matters? A mixed methods study of treatment preferences and priorities among people with epilepsy in the UK

The widening range of treatment options for epilepsy, and their potential outcomes, mean decisions about treatment for people with epilepsy (PWE) are often complex. While antiepileptic drugs (AEDs) represent the mainstay of treatment, other potential nondrug interventions are gaining in importance. These treatments all have the potential for harming those using them, as well as bringing benefits. This study examined the views and experiences of PWE about a range of treatment options. We used both qualitative and quantitative approaches - a series of depth-narrative interviews, followed by a large-scale survey. Treatment options and healthcare priorities deemed important by at least 10% of interview participants were then addressed as a series of statements in the follow-on survey questionnaire. Quantitative responses supported healthcare priorities identified through the qualitative interviews. The key goal of treatment among study participants was to be able to live 'a normal life'. Important physical, psychological, and life benefits of treatment were identified - most being the direct consequence of improved seizure control. One psychological benefit, reduced worry, was also identified as an important treatment goal. All participants viewed AEDs as appropriate first-line treatment; and since adverse effects of AEDs had implications for individual levels of daily function and wellbeing, their appropriate management was considered important. In contrast, surgery was almost always regarded as the treatment of last resort. Despite lack of research evidence supporting their use, participants were interested in complementary therapies as adjunctive treatment and a means of coping with having epilepsy, with yoga and meditation of particular interest. An important finding was the desire for targeted services to help with memory problems, as was the call to increase availability of psychological/counseling services. Our findings emphasize the importance of providing treatment responsive to the life context of individual patients. They highlight not only the level of demand for specific treatment options, but also the need for high-quality evidence to support future investment in their provision.

Maternal epilepsy and behavioral development of the child: Family factors do matter

PURPOSE

The purpose of the study was to examine whether mothers with epilepsy experience family problems and to investigate the possible mediating role of distinct family factors in the relationship between maternal epilepsy and child behavioral problems, in which it is also investigated whether more proximal family factors mediate the more distal family factors.

METHODS

In an observational study, with children identified from the European Registry of Antiepileptic Drugs and Pregnancy database in the Netherlands (EURAP-NL), parents completed questionnaires on maternal epilepsy, family factors (proximal, distal, contextual, global), and child behavior. Hierarchical multilevel regression analyses were performed to examine the relative contribution of epilepsy-related and family factors on child internalizing and externalizing problems.

RESULTS

Between January 2015 and March 2018, the questionnaires were completed for 175 children. Mothers with epilepsy showed significantly more parenting stress and problems with parenting than mothers from the general population. Family factors were significantly associated with child behavioral problems. For internalizing problems, maternal epilepsy, global, contextual, and distal family factors were each found to have significant added value. Distal family factors contributed most to internalizing problems and showed a mediating role for epilepsy-related factors and previous added family factors in the model. Global, contextual, distal, and proximal factors were all found to be significant contributors to externalizing problems, with the factor most proximal to the child (quality of parent-child interaction) showing the largest effect.

DISCUSSION

Including family factors in research regarding children of mothers with epilepsy is important as they can have a contribution additional to the teratogenic risks of prenatal exposure to antiepileptic drugs (AEDs). Family factors, in particular distal and proximal family factors, can weaken or strengthen child development and may provide starting points for interventions.

Neural response to stress and perceived stress differ in patients with left temporal lobe epilepsy

Patients with epilepsy are often able to predict seizure occurrence subsequent to an acute stress experience. However, neuroimaging investigations into the neural basis of this relationship or the potential influence of perceived life stress are limited. The current study assessed the relationship between perceived stress and the neurobehavioral response to stress in patients with left temporal lobe epilepsy (LTLE) and healthy controls (HCs) using heart rate, salivary cortisol level, and functional magnetic resonance imaging and compared these effects between HCs and LTLE. Matched on perceived stress levels, groups of 36 patients with LTLE and 36 HCs completed the Montreal Imaging Stress Task, with control and stress math task conditions. Among LTLEs, 27 reported that prior (acute) stress affected their seizures (LTLES+), while nine did not (LTLES-). The results revealed that increased perceived stress was associated with seizure frequency in LTLE. Further, cortisol secretion was greater in LTLE, but did not vary with perceived stress as observed in HCs. A linear mixed-effects analysis revealed that as perceived stress increased, activation in the hippocampal complex (parahippocampal gyrus and hippocampus) decreased during stressful math in the LTLES+, increased in HCs, but did not vary in the LTLES-. Task-based functional connectivity analyses revealed LTLE differences in hippocampal functional connectivity with sensory cortex specific to stressor modalities. We argue that the current study demonstrates an inhibitory hippocampal mechanism underlying differences in resilience to stress between HCs and LTLE, as well as LTLE patients who report stress as a precipitant of seizures.

The Relationship Between Epilepsy and Anxiety Disorders

PURPOSE OF REVIEW

The current review aims at providing an overview of relevant aspects of anxiety symptoms and anxiety disorders (AD) in adults patients with epilepsy (PWE).

RECENT FINDINGS

Firstly, the appropriate diagnosis of type of anxiety symptoms and AD in PWE will be presented. Anxiety symptoms are often peri-ictal and classified in relation to their temporal occurrence to seizures. Anxiety symptoms are of three types: preictal (preceding a seizure), ictal (presenting as part of the seizure symptoms and signs), and postictal (occurring within 72 h of a seizure). AD are diagnosed in the interictal period and occur independently of seizures. Four specific AD in PWE can be objectified: anticipatory anxiety of epileptic seizures (AAS), seizure phobia, epileptic social phobia, and epileptic panic disorder. Secondly, the bidirectional pathophysiological relationship between anxiety and epilepsy will be described. Anxiety is a trigger for seizures in some patients, and the notion of stress and arousal is essential to understand the relationship between anxiety and seizure. Moreover, seizures arising from the limbic network especially involving amygdala, which may express fear-related semiology, provide insight into the pathophysiology of AD comorbidities. Thirdly, the methods of screening for AD and anxiety symptoms will be detailed. Fourthly, the pharmacological and psychobehavioral management of anxiety symptoms and AD in PWE will be presented. Arousal-based approaches for preictal and ictal symptoms and anxiety-based approaches for postictal and interictal symptoms will be presented. Despite lack of evidence-based approaches, it is recognized that management of epilepsy is not only about controlling seizures, but also depends heavily on detecting, correctly diagnosing, and appropriately managing anxiety symptoms and AD comorbidities, in order to maximize quality of life. Improving self-control and self-efficacy is of fundamental importance in the management of PWE. Further rigorously designed studies focusing on anxiety symptoms and AD are essential to improve the overall care of PWE.

The safety of treating newly diagnosed epilepsy

INTRODUCTION

Epilepsy is a serious chronic neurological disorder manifested by an enduring symptomatic predisposition to seizures. Newly diagnosed individuals face increased morbidity, mortality, and socioeconomic costs. Anti-epileptic drug therapy is the treatment usually prescribed, which has efficacy in seizure control and mitigating long-term mortality.

AREAS COVERED

Safety of anti-epileptic drug therapy in adults with a focus in newly diagnosed patients. Areas covered include the most commonly experienced adverse drug effects, as well as those with the highest impacts on drug tolerability, quality of life, morbidity and mortality. Evidence was also reviewed to identify clinical strategies to improve the safety of anti-epileptic drug therapy.

EXPERT OPINION

Anti-epileptic drugs (AEDs) are mostly effective and well tolerated. However, a lack of standardised reporting of adverse drug effects in trials and in clinical practice provides an obstacle for evaluation of which adverse drug effects need to be prioritised in management. Improvement in the reporting of cognitive and other effects, as well as improved precision medicine and pharmacogenomics to target the incidence of high-mortality idiosyncratic reactions, will help to reduce the harm of AEDs in people newly diagnosed with epilepsy.

"Seizures have become a means of somehow learning things about myself" - A qualitative study of the development of self-efficacy and mastery during a psychotherapeutic intervention for people with epilepsy

BACKGROUND

Psychological interventions may enhance health-related quality of life in people with epilepsy. The concepts of self-efficacy and mastery may be particularly relevant in the context of epilepsy. To date, the investigation of psychological interventions has not included a qualitative analysis of the effects of such interventions on the interrelation between mastery and general and epilepsy-specific self-efficacy. This qualitative study aimed to explore the relationship between the lived experiences of these concepts in people with epilepsy who participated in a resource-oriented and mindfulness-based psychotherapeutic intervention delivered on a one-to-one basis in an outpatient setting.

METHODS

Semi-structured pre- and postintervention interviews were conducted with people with epilepsy who participated in a six-month resource-oriented and mindfulness-based intervention. The formulation of intervention goals was based on the preintervention interviews. The intervention involved regular one-to-one interactions with the therapist, journal-keeping, and mindfulness-based relaxation. Qualitative content analysis of pre- and posttherapy interviews was conducted to characterize changes in subjective experiences.

RESULTS

Nine people with epilepsy aged 18-59 years participated in 9 to 22 (median 13) sessions. The following six main themes emerged: (A) Encouragement of individual solutions, (B) Awareness of the link of personal traits with seizure-related worries, (C) How to develop self-efficacy, (D) Shaping everyday life in a way that is good for oneself (general self-efficacy), (E) Coping with seizures (seizure-related self-efficacy), (F) Epilepsy as a means of increasing self-knowledge and control over one's life (sense of mastery). The patients' development of self-efficacy was motivated by their personal initial goals and facilitated by the encouragement to find individual solutions and an increased awareness of the link of personal traits with seizure-related worries. A sense of mastery only emerged through the development of general self-efficacy and as a result of the active self-examination prompted by the challenge of living with epilepsy.

CONCLUSION

The qualitative differences observed before and after a psychotherapeutic intervention for individuals with epilepsy increase our understanding of the complex process of psychotherapy-associated change involving self-efficacy and mastery and highlight the contribution that qualitative research approaches can make.

Psychological treatments for adults and children with epilepsy: Evidence-based recommendations by the International League Against Epilepsy Psychology Task Force

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 challenges associated with epilepsy and its treatments.

A pilot randomised controlled trial of a home-based writing intervention for individuals with seizures

OBJECTIVE

We investigated the feasibility, acceptability and preliminary effectiveness of a writing intervention for individuals with epilepsy or psychogenic nonepileptic seizures.

METHODS

Individuals were randomised to write about potentially 'therapeutic' topics (n = 43) or about their daily events (n = 25). Participants were asked to write on four separate occasions for at least 20 min. Repeated-measures analysis of variance was used to investigate change in measures of health-related quality of life (NEWQoL-6D), depression (NDDI-E), anxiety (GAD-7) and illness perception (B-IPQ) from baseline to one and three-month follow-ups. Qualitative and quantitative data taken from a Writing Task Questionnaire was analysed between the two conditions.

RESULTS

Recruitment was acceptable with 52% of those randomised completing the full writing intervention. In both conditions, participants wrote for longer than 20 min suggesting those who completed the study engaged well with the procedure. Greater benefits were observed in the 'therapeutic' condition (p < 0.05), which was associated with an improvement in health-related quality of life at one-month follow-up (p = 0.02). No differences were found in the other measures.

CONCLUSIONS

A writing intervention is acceptable in this population. Self-reported benefits were modest, suggesting therapeutic writing may be more suitable as a supplement to other therapies rather than a stand-alone therapeutic intervention.

Mobile Software as a Medical Device (SaMD) for the Treatment of Epilepsy: Development of Digital Therapeutics Comprising Behavioral and Music-Based Interventions for Neurological Disorders

Digital health technologies for people with epilepsy (PWE) include internet-based resources and mobile apps for seizure management. Since non-pharmacological interventions, such as listening to specific Mozart's compositions, cognitive therapy, psychosocial and educational interventions were shown to reduce epileptic seizures, these modalities can be integrated into mobile software and delivered by mobile medical apps as digital therapeutics. Herein, we describe: (1) a survey study among PWE about preferences to use mobile software for seizure control, (2) a rationale for developing digital therapies for epilepsy, (3) creation of proof-of-concept mobile software intended for use as an adjunct digital therapeutic to reduce seizures, and (4) broader applications of digital therapeutics for the treatment of epilepsy and other chronic disorders. A questionnaire was used to survey PWE with respect to preferred features in a mobile app for seizure control. Results from the survey suggested that over 90% of responders would be interested in using a mobile app to manage their seizures, while 75% were interested in listening to specific music that can reduce seizures. To define digital therapeutic for the treatment of epilepsy, we designed and created a proof-of-concept mobile software providing digital content intended to reduce seizures. The rationale for all components of such digital therapeutic is described. The resulting web-based app delivered a combination of epilepsy self-care, behavioral interventions, medication reminders and the antiseizure music, such as the Mozart's sonata K.448. To improve long-term patient engagement, integration of mobile medical app with music and multimedia streaming via smartphones, tablets and computers is also discussed. This work aims toward development and regulatory clearance of software as medical device (SaMD) for seizure control, yielding the adjunct digital therapeutic for epilepsy, and subsequently a drug-device combination product together with specific antiseizure medications. Mobile medical apps, music, therapeutic video games and their combinations with prescription medications present new opportunities to integrate pharmacological and non-pharmacological interventions for PWE, as well as those living with other chronic disorders, including depression and pain.

The Indirect Path From Mindful Parenting to Emotional Problems in Adolescents: The Role of Maternal Warmth and Adolescents' Mindfulness

Mindfulness has been demonstrated to have positive effects on children’s emotional functioning, and adaptive parenting practices are associated with fewer emotional problems. However, the association between mindful parenting and adolescent emotional problems has not been studied much. In the current study, the indirect path from mindful parenting to adolescent emotional problems was examined, with maternal warmth and adolescent dispositional mindfulness as potential mediators. A sample of 168 mother–child dyads participated in this study. A serial indirect effects model showed mother’s mindful parenting could decrease adolescent emotional problems through adolescent’s perceived maternal warmth and their dispositional mindfulness. Findings of this study imply that intervention in mindful parenting may have benefits for adolescents’ emotional problems through enhancing maternal warmth and children’s trait mindfulness.

Positive psychological interventions for people with epilepsy: An assessment on factors related to intervention participation

BACKGROUND

Positive psychological interventions (PPI) are increasingly employed as a coping strategy with physical and mental conditions, including neurological diseases. Its effectiveness on improving wellbeing in people with epilepsy (PWE) has been shown in a few studies. This study aimed to explore factors related to participants' willingness to engage in psychological interventions from the perspective of patients with epilepsy.

METHODS

Participants answered a needs assessment questionnaire eliciting information about their illness perception (Brief Illness Perception Questionnaire (Brief-IPQ)), emotions (Hospital Anxiety and Depression Scale (HADS)), willingness to participate in psychological interventions, preferences in types of PPI and intervention designs, as well as barriers in seeking mental health services.

RESULTS

A total of 154 patients with epilepsy participated, with a mean age of 37.3years (range 16-86years). Most patients had focal epilepsy (68.2%), and drug-resistant (59.1%). Majority (71.4%) of them indicated a strong willingness to participate in PPI. Out of nine types of PPI, character strengths, mindfulness-based and expressive-based interventions were highly preferred. Those with negative illness perception (p=0.001), anxiety (p=0.004), and being unemployed (p=0.048) were more willing to participate in PPI. Most participants preferred group rather than individual session, and a shorter duration (30min) was favored by most.

CONCLUSION

This study captured the self-report willingness to participate in psychological interventions. Findings suggested that psychological interventions delivered in short-group session were highly preferred. Future study is required to determine the feasibility of such design for patients with epilepsy.

Behavioral interventions as a treatment for epilepsy: A multicenter randomized controlled trial

OBJECTIVE

To evaluate the effect of a stress-reduction intervention in participants with medication-resistant epilepsy.

METHODS

Adults with medication-resistant focal epilepsy (n = 66) were recruited from 3 centers and randomized to 1 of 2 interventions: (1) progressive muscle relaxation (PMR) with diaphragmatic breathing, or (2) control focused-attention activity with extremity movements. Following an 8-week baseline period, participants began 12 weeks of double-blind treatment. Daily self-reported mood and stress ratings plus seizure counts were completed by participants using an electronic diary, and no medication adjustments were permitted. The primary outcome was percent reduction in seizure frequency per 28 days comparing baseline and treatment; secondary outcomes included stress reduction and stress-seizure interaction.

RESULTS

In the 66 participants in the intention-to-treat analysis, seizure frequency was reduced from baseline in both treatment groups (PMR: 29%, p < 0.05; focused attention: 25%, p < 0.05). PMR and focused attention did not differ in seizure reduction (p = 0.38), although PMR was associated with stress reduction relative to focused attention (p < 0.05). Daily stress was not a predictor of seizures.

CONCLUSIONS

Both PMR and the focused-attention groups showed reduced seizure frequency compared to baseline in participants with medication-resistant focal seizures, although the 2 treatments did not differ. PMR was more effective than focused attention in reducing self-reported stress.

Harnessing neural stem cells for treating psychiatric symptoms associated with fetal alcohol spectrum disorder and epilepsy

Brain insults with progressive neurodegeneration are inherent in pathological symptoms that represent many psychiatric illnesses. Neural network disruptions characterized by impaired neurogenesis have been recognized to precede, accompany, and possibly even exacerbate the evolution and progression of symptoms of psychiatric disorders. Here, we focus on the neurodegeneration and the resulting psychiatric symptoms observed in fetal alcohol spectrum disorder and epilepsy, in an effort to show that these two diseases are candidate targets for stem cell therapy. In particular, we provide preclinical evidence in the transplantation of neural stem cells (NSCs) in both conditions, highlighting the potential of this cell-based treatment for correcting the psychiatric symptoms that plague these two disorders. Additionally, we discuss the challenges of NSC transplantation and offer insights into the mechanisms that may mediate the therapeutic benefits and can be exploited to overcome the hurdles of translating this therapy from the laboratory to the clinic. Our ultimate goal is to advance stem cell therapy for the treatment of psychiatric disorders.

Psychological treatments for people with epilepsy

BACKGROUND

Given the significant impact epilepsy can have on the health-related quality of life (HRQoL) of individuals with epilepsy and their families, there is great clinical interest in evidence-based psychological treatments, aimed at enhancing psychological well-being in people with epilepsy. A review of the current evidence was needed to assess the effects of psychological treatments for people with epilepsy on HRQoL outcomes, in order to inform future therapeutic recommendations and research designs.

OBJECTIVES

To assess the effects of psychological treatments for people with epilepsy on HRQoL outcomes.

SEARCH METHODS

We searched the following databases on 20 September 2016, without language restrictions: Cochrane Epilepsy Group Specialized Register, CENTRAL, MEDLINE PsycINFO, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP). We screened the references from included studies and relevant reviews, and contacted researchers in the field for unpublished studies.

SELECTION CRITERIA

We considered randomized controlled trials (RCTs) and quasi-RCTs for this review. HRQoL was the main outcome measure. For the operational definition of 'psychological treatments', we included a broad range of treatments that used psychological or behavioral techniques designed to improve HRQoL, seizure frequency and severity, and psychiatric comorbidities for adults and children with epilepsy, compared to treatment as usual (TAU) or an active control group.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by the Cochrane Collaboration.

MAIN RESULTS

We included 24 completed RCTs, with a total of 2439 participants. Eleven studies investigated psychological interventions, such as cognitive, behavioral, and mindfulness-based interventions. The remaining studies were classified as educational interventions (N = 7), self-management interventions (N = 3), adherence interventions (N = 1), and mixed interventions (N = 2). Two studies investigated interventions for children and adolescents, and five studies investigated interventions for adolescents and adults. Based on satisfactory clinical and methodological homogeneity, we pooled data from six adult studies, two studies on adolescents and adults, and one on adolescents and young adults (468 participants) for HRQoL, measured with the Quality of Life in Epilepsy-31 (QOLIE-31). We found significant mean changes for the QOLIE-31 total score and six subscales (emotional well-being, energy and fatigue, overall QoL, seizure worry, medication effects, and cognitive functioning). The mean changes of the QOLIE-31 total score (mean improvement of 5.68 points (95% CI 3.11 to 8.24; P < 0.0001), and three subscales, emotional well-being (mean improvement of 7.03 points (95% CI 2.51 to 11.54; P = 0.002); energy and Fatigue (mean improvement of 6.90 points (95% CI 3.49 to 10.31; P < 0.0001); and overall QoL (mean improvement of 6.47 points (95% CI 2.68 to 10.25; P = 0.0008) exceeded the threshold of minimally important change (MIC), indicating a clinically meaningful post-intervention improvement of QoL. We downgraded the quality of the evidence provided by the meta-analysis because of serious risk of bias in some of the included studies. Consequentially, these results provided evidence of moderate quality that psychological treatments for adults with epilepsy may enhance overall QoL in people with epilepsy.

AUTHORS' CONCLUSIONS

Implications for practice: Psychological interventions and self-management interventions improved QoL, and emotional well-being, and reduced fatigue in adults and adolescents with epilepsy. Adjunctive use of psychological treatments for adults and adolescents with epilepsy may provide additional benefits to QoL in those who incorporate patient-centered management.

IMPLICATIONS FOR RESEARCH

Authors should strictly adhere to the CONSORT guidelines to improve the quality of reporting on their interventions. A thorough description of the intervention protocol is necessary to ensure reproducibility.When researching psychological treatments for people with epilepsy, the use of Quality of Life in Epilepsy Inventories (QOLIE-31, QOLIE-31-P, and QOLIE-89) would increase comparability. There is a critical gap in pediatric RCTs for psychological treatments, particularly those that use an epilepsy-specific measure of HRQoL.Finally, in order to increase the overall quality of study designs, adequate randomization with allocation concealment and blinded outcome assessment should be pursued when conducting RCTs. As attrition is often high in research that requires active participant participation, an intention-to-treat analysis should be carried out.
