Why epilepsy challenges social life

Social cognition in Idiopathic generalised epilepsies

Social cognition is a set of mental skills necessary to create satisfactory interpersonal relationships and feel a sense of belonging to a social group. Its deficits significantly reduce the quality of life in people with epilepsy. Studies on social cognition and its impairments focus predominantly on people with focal epilepsies. Idiopathic generalised epilepsies are a group of diseases that share similar clinical, prognostic and electrographic characteristics. Despite their typically normal intelligence, people with Idiopathic generalised epilepsies can suffer from learning disabilities and executive dysfunctions. Current studies also suggest social cognition impairments, but their results are inconsistent. This review offers the latest knowledge of social cognition in adults with Idiopathic generalised epilepsies. In addition, we provide an overview of the most frequently used assessment methods. We explain possible reasons for different outcomes and discuss future research perspectives.

Reduced eye gaze fixation during emotion recognition among patients with temporal lobe epilepsy

OBJECTIVES

To investigate the facial scan patterns during emotion recognition (ER) through the dynamic facial expression task and the awareness of social interference test (TASIT) using eye tracking (ET) technology, and to find some ET indicators that can accurately depict the ER process, which is a beneficial supplement to existing ER assessment tools.

METHOD

Ninety-six patients with TLE and 88 healthy controls (HCs) were recruited. All participants watched the dynamic facial expression task and TASIT including a synchronized eye movement recording and recognized the emotion (anger, disgust, happiness, or sadness). The accuracy of ER was recorded. The first fixation time, first fixation duration, dwell time, and fixation count were selected and analyzed.

RESULTS

TLE patients exhibited ER impairment especially for disgust (Z =  - 3.391; p = 0.001) and sadness (Z =  - 3.145; p = 0.002). TLE patients fixated less on the face, as evidenced by the reduced fixation count (Z =  - 2.549; p = 0.011) of the face and a significant decrease in the fixation count rate (Z =  - 1.993; p = 0.046). During the dynamic facial expression task, TLE patients focused less on the eyes, as evidenced by the decreased first fixation duration (Z =  - 4.322; p = 0.000), dwell time (Z =  - 4.083; p = 0.000), and fixation count (Z =  - 3.699; p = 0.000) of the eyes.

CONCLUSION

TLE patients had ER impairment, especially regarding negative emotions, which may be attributable to their reduced fixation on the eyes during ER, and the increased fixation on the mouth could be a compensatory effect to improve ER performance. Eye-tracking technology could provide the process indicators of ER, and is a valuable supplement to traditional ER assessment tasks.

Caregiver burden and its predictors in adult epilepsy patients

OBJECTIVE

The aim of this study was to evaluate caregiver burden and factors associated with caregiver burden in caregivers of adults with epilepsy.

MATERIALS AND METHODS

This descriptive cross-sectional study was conducted with 107 patients with epilepsy and 107 their primary caregivers. Personal information form including sociodemographic data and Zarit Caregiver Burden Inventory (ZBI), were used for caregivers, and patient information form, Montreal Cognitive Assessment Scale (MoCA), Hospital Anxiety and Depression Scale (HADS), Epilepsy Quality of Life Scale (QoLIE-31) and Stigma Scale were used for patients.

RESULTS

Caregiver burden was found to be related to gender (p = 0.047), marital status (p = 0.008), income (p = 0.003), education level (p = 0.05) age at onset of epilepsy (p = 0.025) and type of therapy (p = 0.005). The scale scores for cognitive functions (p < 0.001), stigma (p < 0.001), anxiety (p = 0.001), depression (p = 0.005), and quality of life (p < 0.001) of the patient showed significant correlations with caregiver burden. In addition, caregiver burden was found to correlate with some caregiver characteristics such as caregivers' age (p = 0.041), gender (p < 0.001), education (p < 0.001), income (p = 0.001) and relationship with the patient (p = 0.016). Time spent on caregiving per day was also positively correlated with caregiving burden (p < 0.001). In regression analysis, the gender of the caregiver, the gender of the patient, the stigma level of patient, and the type of treatment were found to be predictors of care burden (p < 0.05, R2 = 0.61).

CONCLUSION

It was found that two-thirds of the families of patients with epilepsy experienced varying degrees of caregiver burden. In addition, it was determined that caregiver burden was associated with sociodemographic and numerous psychosocial factors of the patient as well as the caregiver. It is important that both the caregiver and the patient being cared for are closely evaluated in interventions to reduce the caregiver burden in patients with epilepsy.

Comparison between epileptic seizure prediction and forecasting based on machine learning

Epilepsy affects around 1% of the population worldwide. Anti-epileptic drugs are an excellent option for controlling seizure occurrence but do not work for around one-third of patients. Warning devices employing seizure prediction or forecasting algorithms could bring patients new-found comfort and quality of life. These algorithms would attempt to detect a seizure's preictal period, a transitional moment between regular brain activity and the seizure, and relay this information to the user. Over the years, many seizure prediction studies using Electroencephalogram-based methodologies have been developed, triggering an alarm when detecting the preictal period. Recent studies have suggested a shift in view from prediction to forecasting. Seizure forecasting takes a probabilistic approach to the problem in question instead of the crisp approach of seizure prediction. In this field of study, the triggered alarm to symbolize the detection of a preictal period is substituted by a constant risk assessment analysis. The present work aims to explore methodologies capable of seizure forecasting and establish a comparison with seizure prediction results. Using 40 patients from the EPILEPSIAE database, we developed several patient-specific prediction and forecasting algorithms with different classifiers (a Logistic Regression, a 15 Support Vector Machines ensemble, and a 15 Shallow Neural Networks ensemble). Results show an increase of the seizure sensitivity in forecasting relative to prediction of up to 146% and in the number of patients that displayed an improvement over chance of up to 300%. These results suggest that a seizure forecasting methodology may be more suitable for seizure warning devices than a seizure prediction one.

Dynamic facial emotion recognition and affective prosody recognition are associated in patients with temporal lobe epilepsy

Deficits in facial emotion recognition have frequently been established in temporal lobe epilepsy (TLE). However, static, rather than dynamic emotion recognition paradigms have been applied. Affective prosody has been insufficiently studied in TLE, and there is a lack of studies investigating associations between auditory and visual emotion recognition. We wished to investigate potential deficits in a dynamic morph task of facial emotion recognition and in an affective prosody recognition task, as well as associations between both tasks. 25 patients with TLE and 24 healthy controls (CG) performed a morph task with faces continuously changing in their emotional intensity. They had to press a button, as soon as they were able to recognize the emotion expressed, and label it accordingly. In the auditory task, subjects listened to neutral sentences spoken in varying emotional tones, and labeled the emotions. Correlation analyses were conducted across both tasks. TLE patients showed significantly reduced prosody recognition compared to CG, and in the morph task, there was a statistical trend towards significantly reduced performance for TLE. Recognition rates in both tasks were significantly associated. TLE patients show deficits in affective prosody recognition, and they may also be impaired in a morph task with dynamically changing facial expressions. Impairments in basic social-cognitive tasks in TLE seem to be modality-independent.

The burden of chronic drug-refractory focal onset epilepsy: Can it be prevented?

Despite the many therapeutic options for epilepsy available today, a third of patients still have poorly controlled epilepsy. Over the years, their transition through lines of treatment exposes them to increased risk of disease progression, mortality, morbidity, mental distress, and not least significantly impaired quality of life (QoL). The present review explores the multiple factors contributing to the impairment of health-related QoL in PWE-including both seizure-related and non seizure-related. The analysis aims to identify potential areas of intervention and strategies for a more holistic approach to epilepsy care and inform policy-makers and healthcare providers in their approach to this condition.

Epilepsy awareness days, weeks, and months: Their roles in the fight against epilepsy and the intersectoral global action plan on epilepsy and other neurological disorders

OBJECTIVES

This research sought to find out the epilepsy awareness days around the world and understand the nature and role of the days in the fight against epilepsy in relation to the Intersectoral Global Action Plan (IGAP) on epilepsy and other neurological disorders (2022-2031).

METHODS

We conducted a review of journal articles. The databases that we searched were ProQuest Central, EBSCOhost Academic Search Complete, EBSCO Medline, PubMed Central, Wiley Online, Directory of Open Access Journals (DOAJ), African Journals Online (AJOL), and Google Scholar. We limited our search to papers of relevance to our subject published between January 2000 and January 2023. We searched 'epilepsy awareness day, week, or month'. From the databases, 13 articles met our inclusion criteria. We augmented our results with a search on Google of articles about epilepsy awareness day, week, or month. We also searched directly on the websites of epilepsy organizations.

RESULTS

We found that epilepsy awareness days fall into these categories: global awareness days (n = 2), awareness months (n = 4), regional awareness weeks (n = 5), and regional awareness days (n = 1). Our search for national awareness days (n = 7) was not comprehensive, and this could be an area for future research. The literature shows that epilepsy awareness days could play a role in (1) reducing knowledge and treatment gaps, (2) increasing participation, (3) unlocking resources, and (4) necessitating policy change and increasing networking. The major role of these dedicated days in the IGAP is to accelerate awareness and advocacy for policy change and improved interventions.

CONCLUSIONS

Epilepsy awareness days are bringing stakeholders together already, and IGAP initiatives could tap into this achievement to accelerate awareness in a cost effective, contextual and collaborative manner. This could be achieved by adopting themes that relate more directly to the IGAP goals. Another important strategy is to motivate countries that do not have national epilepsy days or regions that do not have a regional awareness days, to consider doing one within the confines of resources.

Reduced Cholecystokinin-Expressing Interneuron Input Contributes to Disinhibition of the Hippocampal CA2 Region in a Mouse Model of Temporal Lobe Epilepsy

A significant proportion of temporal lobe epilepsy (TLE) patients experience drug-resistant seizures associated with mesial temporal sclerosis, in which there is extensive cell loss in the hippocampal CA1 and CA3 subfields, with a relative sparing of dentate gyrus granule cells and CA2 pyramidal neurons (PNs). A role for CA2 in seizure generation was suggested based on findings of a reduction in CA2 synaptic inhibition (Williamson and Spencer, 1994) and the presence of interictal-like spike activity in CA2 in resected hippocampal tissue from TLE patients (Wittner et al., 2009). We recently found that in the pilocarpine-induced status epilepticus (PILO-SE) mouse model of TLE there was an increase in CA2 intrinsic excitability associated with a loss of CA2 synaptic inhibition. Furthermore, chemogenetic silencing of CA2 significantly reduced seizure frequency, consistent with a role of CA2 in promoting seizure generation and/or propagation (Whitebirch et al., 2022). In the present study, we explored the cellular basis of this inhibitory deficit using immunohistochemical and electrophysiological approaches in PILO-SE male and female mice. We report a widespread decrease in the density of pro-cholecystokinin-immunopositive (CCK+) interneurons and a functional impairment of CCK+ interneuron-mediated inhibition of CA2 PNs. We also found a disruption in the perisomatic perineuronal net in the CA2 stratum pyramidale. Such pathologic alterations may contribute to an enhanced excitation of CA2 PNs and CA2-dependent seizure activity in the PILO-SE mouse model.SIGNIFICANCE STATEMENT Impaired synaptic inhibition in hippocampal circuits has been identified as a key feature that contributes to the emergence and propagation of seizure activity in human patients and animal models of temporal lobe epilepsy (TLE). Among the hippocampal subfields, the CA2 region is particularly resilient to seizure-associated neurodegeneration and has been suggested to play a key role in seizure activity in TLE. Here we report that perisomatic inhibition of CA2 pyramidal neurons mediated by cholecystokinin-expressing interneurons is selectively reduced in acute hippocampal slices from epileptic mice. Parvalbumin-expressing interneurons, in contrast, appear relatively conserved in epileptic mice. These findings advance our understanding of the cellular mechanisms underlying inhibitory disruption in hippocampal circuits in a mouse model of spontaneous recurring seizures.

Seizure-related stress and arousal responses mediate a relationship between anxiety trait and state in epilepsy

BACKGROUND

Epilepsy causes substantial psychological distress and anxiety, primarily due to seizures. However, the impact of stress responses and changes in arousal and their association with anxiety patterns in patients with epilepsy (PWE) remains unclear. This study aimed to investigate the relationships among seizures, stress and arousal characteristics, and trait and state anxiety characteristics in PWE.

METHODS

Our sample consisted of 159 outpatients with epilepsy recruited from five institutions in Japan in 2020. Participants completed the State-Trait Anxiety Inventory-Form JYZ (STAI) and the Japanese-Stress Arousal Check List (J-SACL). We analyzed the correlations between inventory scores and clinical information. Using principal component analysis (PCA), we derived epilepsy-specific stress/arousal characteristics, which accounted for high arousal and low-stress levels, termed epilepsy-specific stress or arousal response (ESAR), from the J-SACL scores. We conducted a mediation analysis to assess the mediating role of ESAR in the relationship between traits and state anxiety.

RESULTS

We found significant correlations between J-SACL stress and arousal factors (r = -0.845, p < 0.001), ESAR and seizure frequency (r = -0.29, p < 0.001), ESAR and trait anxiety scores on the STAI (r = -0.77, p < 0.0001), and ESAR and state anxiety scores on the STAI (r = -0.60, p < 0.0001). Mediation analysis supported by the Monte Carlo method revealed that ESAR significantly mediated the association between trait and state anxiety.

CONCLUSIONS

These findings elucidate the epilepsy-specific stress and arousal characteristics and their roles in mediating traits and state anxiety. These results may reflect the long-term clinical course and unique emotion recognition tendencies in epilepsy.

Individualized Homeopathic Medicines as Adjunctive Treatment of Pediatric Epilepsy: A Double-Blind, Randomized, Placebo-Controlled Trial

INTRODUCTION

Epilepsy, one of the most common neurological diseases, contributes to 0.5% of the total disease burden. The burden is highest in sub-Saharan Africa, central Asia, central and Andean Latin America, and south-east Asia. Asian countries report an overall prevalence of 6/1,000 and that in India of 5.59/1,000. We examined whether individualized homeopathic medicines (IHMs) can produce a significantly different effect from placebos in treatment of pediatric epilepsy in the context of ongoing standard care (SC) using anti-epileptic drugs (AEDs).

METHODS

The study was a 6-month, double-blind, randomized, placebo-controlled trial (n = 60) conducted at the pediatric outpatient department of a homeopathic hospital in West Bengal, India. Patients were randomized to receive either IHMs plus SC (n = 30) or identical-looking placebos plus SC (n = 30). The primary outcome measure was the Hague Seizure Severity Scale (HASS); secondary outcomes were the Quality of Life in Childhood Epilepsy (QOLCE-16) and the Pediatric Quality of Life inventory (PedsQL) questionnaires; all were measured at baseline and after the 3rd and 6th month of intervention. The intention-to-treat sample was analyzed to detect group differences and effect sizes.

RESULTS

Recruitment and retention rates were 65.2% and 91.7% respectively. Although improvements were greater in the IHMs group than with placebos, with small to medium effect sizes, the inter-group differences were statistically non-significant - for HASS (F 1, 58 = 0.000, p = 1.000, two-way repeated measures analysis of variance), QOLCE-16 (F 1, 58 = 1.428, p = 0.237), PedsQL (2-4 years) (F 1, 8 = 0.685, p = 0.432) and PedsQL (5-18 years) (F 1, 47 = 0.000, p = 0.995). Calcarea carbonica, Ignatia amara, Natrum muriaticum and Phosphorus were the most frequently prescribed medicines. No serious adverse events were reported from either of the two groups.

CONCLUSION

Improvements in the outcome measures were statistically non-significantly greater in the IHMs group than in the placebos group, with small effect sizes. A different trial design and prescribing approach might work better in future trials.

A comparative study of social cognition in epilepsy, brain injury, and Parkinson's disease

The brain regions involved in social cognition and the regulation of social behavior form a widely distributed cortico-subcortical network. Therefore, many neurological disorders could affect social cognition and behavior. A persistent lack of valid tests and a rigid neuropsychological focus on language, attention, executive function, and memory have contributed to a long-standing neglect of social cognition in clinical diagnostics, although the DSM-5 recognizes it as one of the six core dimensions in neurocognitive disorders. To assess for the first time the diagnostic yield of a comprehensive social cognition battery (Networks of Emotion Processing [NEmo]), we administered several emotion recognition and theory of mind tests to three incidental clinical samples with different neurological conditions: temporal lobe epilepsy (n = 30), acquired brain injury (n = 24), Parkinson's disease (n = 19), and a healthy control group (n = 67). A multivariate analysis of covariance was performed to test the effect of group on subscales of the NEmo test battery, controlling for age and performance IQ. The results showed statistically significant differences between clinical groups and healthy controls. No differences were found for gender and lateralization of the predominant lesion side. In our incidental samples, 86% of individuals with temporal lobe epilepsy, 57% of individuals with acquired brain lesion, and 14% of individuals with Parkinson's disease underperformed on tests of social cognition compared with controls. These findings suggest a differential impact of neurological disorders on the risk of impaired social cognition and highlight the need to consider social cognition in diagnostics, counselling, therapy, and rehabilitation.

Revisiting emotion recognition in different types of temporal lobe epilepsy: The influence of facial expression intensity

Temporal lobe epilepsy (TLE) can induce various difficulties in recognizing emotional facial expressions (EFE), particularly for negative valence emotions. However, these difficulties have not been systematically examined according to the localization of the epileptic focus. For this purpose, we used a forced-choice recognition task in which faces expressing fear, sadness, anger, disgust, surprise, or happiness were presented in different intensity levels from moderate to high intensity. The first objective of our study was to evaluate the impact of emotional intensity on the recognition of different categories of EFE in TLE patients compared to control participants. The second objective was to assess the effect of localizationof epileptic focus on the recognition of EFE in patients with medial temporal lobe epilepsy (MTLE) associated or not with hippocampal sclerosis (HS), or lateral temporal lobe epilepsy (LTLE). The results showed that the 272 TLE patients and the 68 control participants were not differently affected by the intensity of EFE. However, we obtained group differences within the clinical population when we took into account the localization of the temporal lobe epileptic focus. As predicted, TLE patients were impaired in recognizing fear and disgust relative to controls. Moreover, the scores of these patients varied according to the localization of the epileptic focus, but not according to the cerebral lateralization of TLE. The facial expression of fear was less well recognized by MTLE patients, with or without HS, and the expression of disgust was less well recognized by LTLE as well as MTLE without HS patients. Moreover, emotional intensity modulated differently the recognition of disgust and surprise of the three patient groups underlying the relevance of using moderate emotional intensity to distinguish the effect of epileptic focus localization. These findings should be taken into account for interpreting the emotional behaviors and deserve to befurther investigated before considering TLE surgical treatment or social cognition interventions in TLE patients.

Chemo-kindling in adult zebrafish alters spatial cognition but not social novelty recognition

In the past decades, zebrafish have gathered immense attention and importance in the field of neurological sciences. In the case of epilepsy, zebrafish have appeared as a promising acute animal model for the screening and identification of potential antiepileptic molecules. However, the necessity for establishing competent chronic models of epilepsy in zebrafish is apparent. In this regard, recently we developed a chemo-kindling zebrafish model with a better clinical resemblance. In the present study, an attempt to examine the effect of pentylenetetrazole (PTZ)-induced kindling on the cognitive functions of zebrafish was made. In brief, adult zebrafish were repetitively given a sub-effective concentration of PTZ, till the onset of clonic-tonic seizures, entitled as kindled. Thereafter, T-maze test and social recognition memory test were conducted to evaluate spatial memory and social novelty recognition memory of the fish. At the end, both the groups were sacrificed and the brains were isolated to estimate neurotransmitter and gene expression levels. It was observed that PTZ kindling induced spatial cognition deficits and lower social exploration in zebrafish. However, it didn't change the novelty recognition memory of kindled zebrafish. The results of genes and neurotransmitters estimations in the brain also supported the behavioural findings. The results concluded that PTZ kindling alters spatial cognitive functions in adult zebrafish without affecting the social novelty recognition memory.

A Comprehensive Review on Anti-Inflammatory Response of Flavonoids in Experimentally-Induced Epileptic Seizures

Flavonoids, a group of natural compounds with phenolic structure, are becoming popular as alternative medicines obtained from plants. These compounds are reported to have various pharmacological properties, including attenuation of inflammatory responses in multiple health issues. Epilepsy is a disorder of the central nervous system implicated with the activation of the inflammatory cascade in the brain. The aim of the present study was to summarize the role of various neuroinflammatory mediators in the onset and progression of epilepsy, and, thereafter, to discuss the flavonoids and their classes, including their biological properties. Further, we highlighted the modulation of anti-inflammatory responses achieved by these substances in different forms of epilepsy, as evident from preclinical studies executed on multiple epilepsy models. Overall, the review summarizes the available evidence of the anti-inflammatory potential of various flavonoids in epilepsy.

Constructive communication patterns as related to relationship satisfaction, seizure severity, and patient activation among people with epilepsy

PURPOSE

People with epilepsy (PWE) must manage their condition properly for both quality and longevity of life. Effective self-management is critical and can be monitored via levels of patient activation (i.e., a continuum of taking a passive vs active role in personal healthcare) and the presence/severity of seizures. One known influencer of self-management is the quality of one's intimate relationship, a documented area of major concern for PWE. Here we examined a critical facet of PWEs' intimate relationships-(un)constructive communication with their partner.

METHODS

Using data from a web-based survey of 89 PWE, and regression-based mediation analyses, we examined associations with patient activation and seizure severity. We added further explanatory utility by examining relationship satisfaction as a mediator of those links.

RESULTS

There were positive links between more constructive communication, more patient activation, and less severe seizures. The explanatory path of constructive communication to better relationship satisfaction to lower seizure severity emerged as a significant partial mediation (i.e., direct effect remained significant), while relationship satisfaction fully mediated (i.e., direct effect became non-significant) the link between constructive communication and greater patient activation.

CONCLUSION

Our results provide insight into how relationship processes may impact the experience of epilepsy, including seizure severity and patient activation. Future research is needed.

A framework for health equity in people living with epilepsy

Epilepsy is a disease where disparities and inequities in risk and outcomes are complex and multifactorial. While most epilepsy research to date has identified several key areas of disparities, we set out to provide a multilevel life course model of epilepsy development, diagnosis, treatment, and outcomes to highlight how these disparities represent true inequities. Our piece also presents three hypothetical cases that highlight how the solutions to address inequities may vary across the lifespan. We then identify four key domains (structural, socio-cultural, health care, and physiological) that contribute to the persistence of inequities in epilepsy risk and outcomes in the United States. Each of these domains, and their core components in the context of epilepsy, are reviewed and discussed. Further, we highlight the connection between domains and key areas of intervention to strive towards health equity. The goal of this work is to highlight these domains while also providing epilepsy researchers and clinicians with broader context of how their work fits into health equity.

Toward social neuropsychology of epilepsy: a meta-analysis on social cognition in epilepsy phenotypes and a critical narrative review on assessment methods

Background

The aim of this review is to (a) characterize social cognition impairments in the domains of emotion recognition (ER) and theory of mind (ToM) in patients with epilepsy and (b) to review assessment tools with a focus on their validity and usability in clinical practice.

Methods

An electronic search for clinical studies investigating social cognition in epilepsy populations vs healthy control subjects (HC) yielded 53 studies for the meta-analysis and descriptive review.

Results

Results suggest that (1) social cognition is significantly impaired in patients with temporal lobe epilepsy (TLE), frontal lobe epilepsy (FLE) and patients with epilepsy not originating within the temporal or frontal lobes including idiopathic generalized epilepsies (eTLE/eFLE); (2) there is no significant difference between eTLE/eFLE and TLE regarding ER, while TLE and FLE patients perform worse than those with eTLE/eFLE, without significant differences between FLE and TLE regarding ToM ability. A descriptive analysis of the most commonly used assessment tools and stimulus material in this field revealed a lack of ecological validity, usability, and economic viability for everyday clinical practice.

Conclusions

Our meta-analysis shows that patients with epilepsy are at a significantly increased risk of deficits in social cognition. However, the underlying multifactorial mechanisms remain unclear. Future research should therefore specifically address the impairment of processing and methodological problems of testing.

Face-induced gamma oscillations and event-related potentials in patients with epilepsy: an intracranial EEG study

Background

To examine the pathological effect of a mesial temporal seizure onset zone (SOZ) on local and inter-regional response to faces in the amygdala and other structures of the temporal lobe.

Methods

Intracranial EEG data was obtained from the amygdala, hippocampus, fusiform gyrus and parahippocampal gyrus of nine patients with drug-refractory epilepsy during visual stimulation with faces and mosaics. We analyzed event-related potentials (ERP), gamma frequency power, phase-amplitude coupling and phase-slope-index and compared the results between patients with versus without a mesial temporal SOZ.

Results

In the amygdala and fusiform gyrus, faces triggered higher ERP amplitudes compared to mosaics in both patient groups and higher gamma power in patients without a mesial temporal SOZ. In the hippocampus, famous faces triggered higher gamma power for both groups combined but did not affect ERPs in either group. The differentiated ERP response to famous faces in the parahippocampal gyrus was more pronounced in patients without a mesial temporal SOZ. Phase-amplitude coupling and phase-slope-index results yielded bidirectional modulation between amygdala and fusiform gyrus, and predominately unidirectional modulation between parahippocampal gyrus and hippocampus.

Conclusions

A mesial temporal SOZ was associated with an impaired response to faces in the amygdala, fusiform gyrus and parahippocampal gyrus in our patients. Compared to this, the response to faces in the hippocampus was impaired in patients with, as well as without, a mesial temporal SOZ. Our results support existing evidence for face processing deficits in patients with a mesial temporal SOZ and suggest the pathological effect of a mesial temporal SOZ on the amygdala to play a pivotal role in this matter in particular.

Functional patterns of neural activation during vocal emotion recognition in youth with and without refractory epilepsy

Epilepsy has been associated with deficits in the social cognitive ability to decode others' nonverbal cues to infer their emotional intent (emotion recognition). Studies have begun to identify potential neural correlates of these deficits, but have focused primarily on one type of nonverbal cue (facial expressions) to the detriment of other crucial social signals that inform the tenor of social interactions (e.g., tone of voice). Less is known about how individuals with epilepsy process these forms of social stimuli, with a particular gap in knowledge about representation of vocal cues in the developing brain. The current study compared vocal emotion recognition skills and functional patterns of neural activation to emotional voices in youth with and without refractory focal epilepsy. We made novel use of inter-subject pattern analysis to determine brain areas in which activation to emotional voices was predictive of epilepsy status. Results indicated that youth with epilepsy were comparatively less able to infer emotional intent in vocal expressions than their typically developing peers. Activation to vocal emotional expressions in regions of the mentalizing and/or default mode network (e.g., right temporo-parietal junction, right hippocampus, right medial prefrontal cortex, among others) differentiated youth with and without epilepsy. These results are consistent with emerging evidence that pediatric epilepsy is associated with altered function in neural networks subserving social cognitive abilities. Our results contribute to ongoing efforts to understand the neural markers of social cognitive deficits in pediatric epilepsy, in order to better tailor and funnel interventions to this group of youth at risk for poor social outcomes.

Cognitive Impairment in People with Epilepsy

People with epilepsy frequently have cognitive impairment. The majority of cognitive problems is influenced by a variety of interlinked factors, including the early onset of epilepsy and the frequency, intensity and duration of seizures, along with the anti-epileptic drug treatment. With a systematic review, we investigate significant factors about the cognitive impairment in epilepsy. Most cognitive problems in adult people with epilepsy include memory, attention and executive function deficits. However, which cognitive area is mainly affected highly depends on the location of epileptic activity. Moreover, modifications in signalling pathways and neuronal networks have an essential role in both the pathophysiology of epilepsy and in the mechanism responsible for cognitive impairment. Additionally, studies have shown that the use of polytherapy in the treatment of epilepsy with anti-epileptic drugs (AEDs) heightens the risk for cognitive impairment. It can be challenging to distinguish the contribution of each factor, because they are often closely intertwined.

Affective Empathy, Theory of Mind and Social Functioning in Patients With Focal Epilepsy

OBJECTIVE

Social cognition comprises basic and more complex functions, such as theory of mind (ToM) and affective empathy. Although everyday social interactions may be impaired if such higher-order social cognitive functions are compromised, associations between social functioning and social cognition in people with focal epilepsy (PWFE) are still poorly understood. We used a novel, naturalistic approach to investigate ToM in PWFE by applying the Movie for the Assessment of Social Cognition (MASC). Furthermore, we studied affective empathy, the relationship between social cognitive parameters and measures of social functioning, as well as between epilepsy focus and ToM.

METHODS

Thirty patients with either temporal (TLE) or frontal lobe epilepsy (FLE) were compared to 29 healthy control subjects (HC). In addition to the MASC, we applied questionnaire measures assessing empathy and everyday social functioning.

RESULTS

PWFE, especially with FLE, performed significantly worse than HC on the MASC. Perceived social integration and social activities, but not affective empathy, were reduced in PWFE. Regression analyses revealed associations between perceived social integration, clinical group status, affective empathy and ToM.

CONCLUSION

PWFE displayed ToM deficits during a naturalistic task, whereas affective empathy was unimpaired. FLE may be associated with especially compromised ToM performance. Social cognition and social functioning appear to be interrelated in PWFE, whose self-perceived levels of social integration and social activities are lower than those of HC. More research into the association between social cognition and social functioning in PWFE is needed, in order to develop tailored intervention programs for these patients.

Marital status among patients with epilepsy in Saudi Arabia

There are no adequate studies on Saudi Arabia regarding the effect of the social environment on marriage among people with epilepsy (PWE). To fill this gap in the literature, we investigated the marital status of PWE to determine the factors affecting their marital prospects. The subjects of the study included PWE aged 18 years or above, recruited between 1998 and 2019 from the Epilepsy Registry of King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. We collected a wide range of socio-demographic data on age, gender, location, education level, employment status, and marital status. In total, 1857 PWE, comprising 1086 men (58.48%) and 771 women (41.52%), were enrolled in the study. The data analysis showed that those 'married' and those who 'had been married' comprised 46.96% of the sample, while those 'never married' comprised 53.04%; 65.37% of the sample held a 'high school diploma or less' or had 'no education', 26.85% reported ongoing university education or had already obtained a bachelor's or higher degree; 50.08% of the respondents were employed, while 47.98% were not. Of the sample, 40.28% resided in Riyadh, whereas 13.14% were from the Asir region. We found that socio-demographic factors, especially employment status, had a major influence on the marital prospects of PWE.

Burden of Chronic and Acute Conditions and Symptoms in People With Epilepsy

BACKGROUND AND OBJECTIVES

People with epilepsy, one-third of whom in the United States are on Medicaid, experience a wide range of chronic and physical comorbidities that influence their care and outcomes. In this study, we examine the burden and racial/ethnic disparities of chronic and acute conditions, injuries, and symptoms in a large and diverse group of people with epilepsy on Medicaid.

METHODS

Using 5 years of Medicaid claims data, we identified adults with epilepsy and used all available claims and diagnoses to identify each person's Clinical Classification Codes groups diagnosed during the study period. Using association rule mining, we identified the top combinations of conditions and stratified these by race/ethnicity to identify potential prevalence disparities. We examined the top combinations of conditions in high utilizers; that is, individuals in the top quartile of hospitalizations and emergency department visits.

RESULTS

Among 81,963 patients, the most common conditions were anxiety and mood disorders (46.5%), hypertension (36.9%), back problems (35.2%), developmental disorders (31.6%), and headache (29.5%). When examining combinations of conditions, anxiety and mood disorders continued to have an outsized prevalence, appearing in nearly every combination. There were notable disparities in disease burden, with American Indians and Alaskan Natives having a substantially higher prevalence of developmental disorders, while Black individuals had a higher prevalence of hypertension. These disparities persisted to the higher-order combinations that included these conditions. High utilizers had a much higher disease burden, with 75.8% having an anxiety or mood disorder, as well as a higher burden of injuries.

DISCUSSION

This study shows a high prevalence of psychiatric and physical conditions and identifies racial and ethnic disparities affecting people with epilepsy. Targeting interventions to consider the comorbidities, race, and ethnicity has potential to improve clinical care and reduce disparities.

Diagnostic Delay in Epilepsy: the Scope of the Problem

PURPOSE OF REVIEW

Diagnostic delay is an increasingly recognized issue in epilepsy. At the same time, there is a clear disparity between public awareness of epilepsy and that of other public health issues. A contributing factor for this seems to be a lack of studies testing interventions designed to improve seizure recognition. In this review, we summarize the main findings from recent studies investigating diagnostic delay in epilepsy, highlighting causes, consequences, and potential interventions in future research that may improve quality of care in this population.

RECENT FINDINGS

Building on prior evidence, diagnostic delay in patients with new-onset focal epilepsy has been identified as an important problem for patients with epilepsy. Such delay in diagnosis can lead to delayed treatment and potentially preventable morbidity and mortality including motor vehicle accidents. Nonmotor seizure semiology appears to be a major contributor for delay; such seizures are largely unrecognized when patients present to emergency departments for care. Improving recognition and diagnosis of recurrent nonmotor seizures in emergency departments represents a significant opportunity for improving time to diagnosis, particularly when patients present following a first lifetime motor seizure and meet diagnostic criteria for epilepsy. Diagnostic delay in epilepsy is a significant public health issue and recent studies have highlighted potential areas for intervention.

Emotion recognition and theory of mind after temporal lobe epilepsy surgery: A systematic review

In order to navigate in our complex social world successfully, it is crucial to maintain and practice cognitive skills that are dedicated to adaptive social functioning. Emerging evidence suggests that besides deficits in declarative memory, executive functions, and language, impairments in social cognition (SC, e.g., emotion recognition, theory of mind) are also present in temporal lobe epilepsy (TLE). The organic and psycho-social consequences of epilepsy surgery might have additional implications regarding this deficit. Here we qualitatively synthesize longitudinal and cross-sectional findings on SC after TLE surgery. A literature search using PubMed and Scopus identified 275 potential articles. Studies were eligible if they (1) included patients with a diagnosis of TLE, (2) included a healthy comparison group, (3) reported original research, (4) were published in peer-reviewed journals and in English language, (5) reported the intervention of epilepsy surgery. Articles that (1) were case studies, (2) did not focus on SC abilities, (3) used interviews or self-report questionnaires to examine SC functions were excluded. A total of 16 original studies assessing emotion recognition (ER) and/or theory of mind (ToM) matched our criteria. The literature suggests that neither ER nor ToM abilities change after surgery: post-surgery patients show similar impairment patterns to pre-surgery patients. Nevertheless, individual improvement or decline could be masked by group comparisons and results should be considered in light of methodological heterogeneity among studies.

Attitudes toward epilepsy in Indonesia

BACKGROUND

Indonesia is the largest island country in the world with diverse ethnicity and cultural backgrounds. This study aimed to understand the variation in attitudes toward epilepsy among the Javanese, Sundanese, and the Minahasa ethnic groups in Indonesia.

METHOD

This study recruited Sundanese from Tasikmalaya and Minahasan from Manado using the Indonesian Public Attitudes Toward Epilepsy (PATE) scale. The results were compared to the Javanese and Malaysian data in previous studies.

RESULT

A total of 200 respondents, 100 from each ethnic group were recruited, with a mean age of 38.51 years. They were predominantly females (54%) and had secondary education level or lower (56.67%). The Javanese had a higher total mean score, indicating poorer attitudes toward epilepsy, as compared to the Minahasan and Sundanese groups. These differences were noted in the personal domain, but not the general domain. There were no significant differences in the mean scores in both personal and general domains between the Minahasan, Sundanese, and Malaysian populations. Subanalysis on the aspects of life showed that the Javanese had a significantly higher score in the aspects of education, marital relationship, and employment.

CONCLUSION

The attitudes toward epilepsy were similar between the Indonesian (Sundanese and the Minahasan) and Malaysian, except the Javanese with poorer attitude. These differences could be socioeconomically or culturally related.

Prevalence of depression and suicidal ideation in persons with epilepsy during the COVID-19 pandemic: A longitudinal study from India

OBJECTIVES

COVID-19 pandemic has disrupted healthcare services for chronic disorders such as epilepsy. In this study, the impact of COVID-19 pandemic on persons with epilepsy (PWE) with regard to their seizure control, depression status, and medication adherence was assessed.

METHODS

After ethical clearance, 449 PWE who had been previously evaluated for depression at All India Institute of Medical Sciences (AIIMS), New Delhi, India, were telephonically revaluated using Mini International Neuropsychiatric Interview and surveyed for source of medication and medication adherence over past 6 months. The prevalence and the association of depression, suicidality, and seizures during pandemic with different PWE variables were determined.

RESULTS

Out of 449 PWE, 70.6% responded. 19.9% were diagnosed positive for depression as per MINI while suicidal ideation was observed in 5.4%. Seventy six (23.9%) PWE reported seizures during pandemic. The incidence was greater in females, unemployed, previously uncontrolled epilepsy, polytherapy, altered use of medications, and depressed PWE. Seizure during pandemic, increased seizure frequency, previous history of depression, and altered use of medications were all significantly associated with depression during COVID-19 pandemic (2.6-95%CI, 1.45-4.73; 1.9-95%CI, 1.01-3.57; 8.8-95%CI, 4.54-17.21; 2.9-95%CI, 1.19-7.24), and polytherapy (2.9-95%CI, 0.92-9.04), seizures during pandemic (3.9-95%CI, 1.45-10.53) and previous history of depression and suicidality, were related with suicidal ideation.

CONCLUSION

COVID-19 pandemic-induced disruptions can be detrimental for PWE, and restoring services to the precovid levels as well as putting appropriate continuity plans in place for care of PWE should be a priority.

The Impact of Social Cognition on the Real-Life of People with Epilepsy

Background. Previous research has demonstrated the impairment of social cognition (SC) in people with epilepsy. It is associated with worse social functioning and quality of life; however, the influence on real-life outcomes is unknown. The purpose of this study was to investigate how SC is associated with epilepsy variables and real-life outcomes (education, employment and relationships) among patients with epilepsy (PWE). Methods. Eighty-one PWE completed tasks of theory of mind (ToM) (faux pas recognition (FPRT) and Happé Strange Stories test (HST)) and emotion recognition (ER) (Reading of the Mind in the Eyes (RMET)). Variables reflecting their education, employment and relationship status were treated as endpoints in search of association with SC. Data from a matched group (n = 30) of healthy controls (HCs) were used for comparison of ToM abilities. Results. ToM scores were lower among PWE as compared to HCs (U = 1816.0, p < 0.0001 (HST), U = 1564.5, p = 0.020 (FPRT)). All SC tests were associated with the level of education (OR = 1.22, 95% confidence interval (CI) = 1.09 to 1.36 (RMET), OR = 1.20, 95% CI = 1.02 to 1.40 (HST), OR = 0.93, 95% CI = 0.87 to 1.00 (FPRT)). The results of ToM and ER testing were not associated with employment (χ² = 33.423, p < 0.0001) if adjusted for the level of education (B = 0.804, OR = 2.23 (95% CI = 1.33 to 3.76), p = 0.002). SC abilities did not differ between PWE who were single and those in a relationship (U = 858.5, p = 0.541 (HST)), t= −1.236, p = 0.220 (RMET), U = 909.5, p = 0.271 (FPRT)). Conclusion. Better social cognition skills are linked to a higher level of education among PWE. SC probably has less influence on professional achievements and interpersonal relationships.

Temporal lobe epilepsy alters neural responses to human and avatar facial expressions in the face perception network

BACKGROUND AND OBJECTIVE

Although avatars are now widely used in advertisement, entertainment, and business today, no study has investigated whether brain lesions in neurological patients interfere with brain activation in response to dynamic avatar facial expressions. The aim of our event-related fMRI study was to compare brain activation differences in people with epilepsy and controls during the processing of fearful and neutral dynamic expressions displayed by human or avatar faces.

METHODS

Using functional magnetic resonance imaging (fMRI), we examined brain responses to dynamic facial expressions of trained actors and their avatar look-alikes in 16 people with temporal lobe epilepsy (TLE) and 26 controls. The actors' fearful and neutral expressions were recorded on video and conveyed onto their avatar look-alikes by face tracking.

RESULTS

Our fMRI results show that people with TLE exhibited reduced response differences between fearful and neutral expressions displayed by humans in the right amygdala and the left superior temporal sulcus (STS). Further, TLE was associated with reduced response differences between human and avatar fearful expressions in the dorsal pathway of the face perception network (STS and inferior frontal gyrus) as well as in the medial prefrontal cortex.

CONCLUSIONS

Taken together, these findings suggest that brain responses to dynamic facial expressions are altered in people with TLE compared to neurologically healthy individuals-regardless of whether the face is human or computer-generated. In TLE, areas sensitive to dynamic facial features and associated with processes relating to the self and others are particularly affected when processing dynamic human and avatar expressions. Our findings highlight that the impact of TLE on facial emotion processing must be extended to artificial faces and should be considered when applying dynamic avatars in the context of neurological conditions.

Dynamic human and avatar facial expressions elicit differential brain responses

Computer-generated characters, so-called avatars, are widely used in advertising, entertainment, human–computer interaction or as research tools to investigate human emotion perception. However, brain responses to avatar and human faces have scarcely been studied to date. As such, it remains unclear whether dynamic facial expressions of avatars evoke different brain responses than dynamic facial expressions of humans. In this study, we designed anthropomorphic avatars animated with motion tracking and tested whether the human brain processes fearful and neutral expressions in human and avatar faces differently. Our fMRI results showed that fearful human expressions evoked stronger responses than fearful avatar expressions in the ventral anterior and posterior cingulate gyrus, the anterior insula, the anterior and posterior superior temporal sulcus, and the inferior frontal gyrus. Fearful expressions in human and avatar faces evoked similar responses in the amygdala. We did not find different responses to neutral human and avatar expressions. Our results highlight differences, but also similarities in the processing of fearful human expressions and fearful avatar expressions even if they are designed to be highly anthropomorphic and animated with motion tracking. This has important consequences for research using dynamic avatars, especially when processes are investigated that involve cortical and subcortical regions.

Associating executive dysfunction with behavioral and socioemotional problems in children with epilepsy. A systematic review

As children with epilepsy may have a number of learning and behavioral problems, it is important that insight into the underlying neurocognitive differences in these children, which may underlie these areas of challenge is gained. Executive function (EF) problems particularly are associated with specific learning abilities as well as behavioral problems. We aim to review systematically the current status of empirical studies on the association between EF problems and behavior and socioemotional problems in children with epilepsy. After search, 26 empirical studies were identified, most of them of moderate quality. Overall, attention problems were the most reported cognitive deficit in test assessment and the most reported problem by parents. In 54% of the studies, children with epilepsy scored below average compared to controls/normative samples on different aspects of EF. Most studies reported behavior problems, which ranged from mild to severe. Forty-two percent of the studies specifically reported relationships between EF deficits and behavioral problems. In the remaining studies, below average neuropsychological functioning seemed to be accompanied by above average reported behavioral problems. The association was most pronounced for cognitive control and attention in relation to externalizing behavior problems. This cognitive control is also associated with social functioning. Relevant epilepsy variables in this relationship were early age at onset and high seizure frequency.Future research should distinguish specific aspects of EF and take age into account, as this provides more insight on the association between EF and behavior in pediatric epilepsy, which makes it possible to develop appropriate and early intervention.

The History of Epilepsy: From Ancient Mystery to Modern Misconception

Epilepsy is an ancient disease, which has fascinated and frightened scientists and laymen alike. Before the working knowledge of the central nervous system, seizures were shrouded in mystery. In antiquity, this disease was accredited to gods and demonic possession, causing those with epilepsy to be feared and isolated. Epilepsy patients continued to face discrimination through the mid-20th century. This discrimination ranged from lack of access to health insurance, jobs, and marriage equality to forced sterilizations. Despite the strides that have been made, there are still many misconceptions globally regarding epilepsy. Studies show that patients with epilepsy in communities that understand the pathology and cause of seizures are generally more successful in social and educational environments. While there has been progress, there is more work which needs to be done to educate people across the globe about the pathology of epilepsy.

Patients' knowledge about epilepsy in a tertiary medical center: A cross-sectional study from Riyadh, Saudi Arabia

OBJECTIVE

Epilepsy is a noncommunicable disease that affects approximately 65 million people worldwide. Its management depends greatly on the self-management capacity of the individual. Patients with epilepsy (PWE) who have a good level of knowledge about their disease tend to have better coping mechanisms, as well as better compliance in taking their antiepileptic drugs (AEDs), which improves overall control of symptoms. This study aimed to evaluate the current patients' knowledge about epilepsy and identify factors associated with knowledge of different aspects of epilepsy and its management in a tertiary medical center in Riyadh, Saudi Arabia.

METHODS

A cross-sectional study was carried out at a tertiary medical center in Riyadh, Saudi Arabia. Participants were included if they had a documented diagnosis of epilepsy and excluded if they were non-Saudi or had nonepileptic seizures. The Arabic version of the Epilepsy Patient Knowledge Questionnaire (EPKQ) was used to assess patient's knowledge of epilepsy definition and etiology, safety concerns, medication compliance, social activities, and legal issues of employment and driving. Fisher's exact and Chi-Square tests were used to investigate differences in knowledge of epilepsy among different segments of participants. Data management and statistical analyses were carried on using the IBM SPSS Statistics for Windows, version 25.

RESULTS

A total of 126 PWE were enrolled in the study. About two-thirds of them were females, and about 68% of them were at least high-school graduates. About one-half of PWE had good knowledge of their condition (>75%), and females had better knowledge than males (p = 0.004). The majority (75.4%) of PWE were knowledgeable about the etiology of epilepsy, about 70% knew that putting a foreign object in a seizing patients' mouth was inappropriate, and only 38% of them did not have adequate knowledge of situations that increase the risk of seizure. About 40% of PWE thought pregnant women should discontinue their AEDs, 53.2% of participants knew what to do when they experience side effects from AEDs, but most of them recognized that they should not automatically stop taking their medications when they stop having seizures. Patients older than 50 years or younger than 21 years of age were less likely to recognize that it was safe for PWE to engage in different social activities (p = 0.042). About 30% of respondents believed that PWE cannot engage in most types of jobs, and more than 50% of participants did not know under which situation PWE can drive.

CONCLUSION

This study revealed that about half of PWE had inadequate knowledge about their disorder. Patients with epilepsy had better knowledge about the causes of their condition compared with safety concerns and the treatment of epilepsy, whereas the majority of participants knew the types of jobs and activities that they could engage in. Hence, educational interventions are needed to promote patients' knowledge, especially in terms of safety and the legalities of employment and driving.

Associations of individual and structural socioeconomic status with cognition and mental distress in pharmacoresistant focal epilepsy

OBJECTIVE

Epilepsy is often associated with low socioeconomic status (SES). People with epilepsy (PWE) also suffer from cognitive dysfunction and mental distress. In the general population, these constraints are related to individual and structural SES. However, in PWE, cognitive dysfunction and mental distress have been mainly attributed to biological factors such as brain lesions or pharmacological treatment, whereas comprehensive studies on possible social determinants are missing. Here, we study associations of individual and structural SES with cognition and mental distress in PWE.

METHODS

We retrospectively studied 340 adult patients with pharmacoresistant focal epilepsy from Berlin treated at a tertiary epilepsy center. Individual SES (education, employment, and income), structural SES (social index of district and neighborhood), and their interactions were examined. Associations between social variables and verbal learning, psychomotor speed, and mental distress were analyzed with multiple regression analyses, controlling for demographic and medical variables and intelligence.

RESULTS

Our sample had lower educational levels and lived more frequently in low SES neighborhoods compared to the general population of Berlin. Thirty percent showed reduced verbal learning, 31% had deficits in psychomotor speed, and 20% revealed significant mental distress. Lower structural SES was related to lower psychomotor speed (ΔR² = 0.9%) and higher mental distress (ΔR² = 1.6%). Employment was related to verbal learning (ΔR² = 0.7%) and psychomotor speed (ΔR² = 1.2%). Income and education were linked to mental distress (ΔR² = 5%). Neighborhood and individual SES covered more than half of the explained variance in mental distress. Furthermore, interactions between individual and structural SES were identified.

CONCLUSION

We confirm cognitive deficits, significant mental distress, and individual and structural social disadvantage in PWE. Our findings indicate that individual and structural SES are related to cognitive and emotional well-being beyond demographic and medical characteristics. As a clinical implication, individual and structural SES should be considered when interpreting neuropsychological findings.

The number of anti-seizure medications mediates the relationship between cognitive performance and quality of life in temporal lobe epilepsy

OBJECTIVES

To assess whether cognitive performance predicts quality of life (QOL) in patients with drug-resistant temporal lobe epilepsy (TLE), using the Epitrack cognitive screening tool, while considering the mediating role of the number of anti-seizure medications (ASMs) and controlling for seizure-related, social, and emotional factors.

METHODS

Seventy-five adult patients with drug-resistant TLE (mean age = 39.76 years, SD = 11.66) underwent a presurgical neuropsychological assessment.

MAIN OUTCOME MEASURES

Cognitive performance (Epitrack), depression (BDI-II), trait anxiety (STAI); and QOL (QOLIE-31) were assessed.

RESULTS

Adjusting for seizure-related, social, and emotional factors, the Epitrack total score significantly contributed to QOL composite score, and energy and cognitive self-rating subscales. We found a significant indirect effect of the Epitrack total score on QOL composite score and seizure worry and social functioning subscales via the number of ASMs.

CONCLUSION

Our findings underline the relevance of cognitive functioning on QOL and the clinical utility of Epitrack to track cognitive side effects of ASMs and, consequently, to predict and manage QOL in this population.

Blunted neural response to emotional faces in the fusiform and superior temporal gyrus may be marker of emotion recognition deficits in pediatric epilepsy

Individuals with epilepsy are at risk for social cognition deficits, including impairments in the ability to recognize nonverbal cues of emotion (i.e., emotion recognition [ER] skills). Such deficits are particularly pronounced in adult patients with childhood-onset seizures and are already evident in children and adolescents with epilepsy. Though these impairments have been linked to blunted neural response to emotional information in faces in adult patients, little is known about the neural correlates of ER deficits in youth with epilepsy. The current study compared ER accuracy and neural response to emotional faces during functional magnetic resonance imaging (fMRI) in youth with intractable focal epilepsy and typically developing youth. Relative to typically developing participants, individuals with epilepsy showed a) reduced accuracy in the ER task and b) blunted response to emotional faces (vs. neutral faces) in the bilateral fusiform gyri and right superior temporal gyrus (STG). Activation in these regions was correlated with performance, suggesting that aberrant response within these face-responsive regions may play a functional role in ER impairments. Reduced engagement of neural circuits relevant to processing socioemotional cues may be markers of risk for social cognitive deficits in youth with focal epilepsy.

Health-related quality of life and associated factors among patients with epilepsy at the University of Gondar comprehensive specialized hospital, northwest Ethiopia

PURPOSE

Epilepsy is a global public health problem that causes a profound physical, psychological and social consequences. However, as such evidence in our country is limited, this study aimed to assess the health-related quality of life (HRQOL) and associated factors among patients with epilepsy.

METHODS

An institution-based cross-sectional study was conducted on 370 patients with epilepsy. The Quality of Life in Epilepsy Inventory-31 (QOLIE-31) was used to measure HRQOL. Multiple linear regression was fitted to assess the association between HRQOL and the independent variables, and a P-value < 0.05 and a 95% confidence interval were used to declare statistical significance.

RESULTS

More than 55% of the participants were male, and the mean age of the participants was 29.64 (11.09) years. The overall HRQOL score was 55.81 (14.00). The scale scores ranged from 46.50 (15.55) to 64.98 (19.43). Out of the seven scales, the energy scale score was the lowest. Frequency of seizure, anxiety, depression, perceived stigma and adverse drug event were negatively associated with HRQOL, whereas social support had a significant positive association.

CONCLUSION

This study revealed that the HRQOL of patients was low and that its energy and emotional scales were the most affected. The presence of depression, anxiety and stigma adversely affected patient HRQOL. Therefore, healthcare professionals should be aware of the emotional state of the role it plays for HRQOL. Interventions aimed at reducing psychosocial problems and stigmatization are also needed to improve the patient HRQOL.

Social cognition in an adult epilepsy patient with developmental amnesia

Reports on social cognition in patients with developmental amnesia resulting from bilateral hippocampal lesions are rare, although the link between social cognition and temporal lobe structures is well established. We present the case of a 23-year-old male epilepsy patient, BM, with developmental amnesia due to perinatal cerebral hypoxia. The patient was examined with neuroimaging and neuropsychological methods and compared to IQ-matched patients with epilepsy to control for effects of epilepsy. In addition, we used a test battery that evaluates emotion recognition and theory of mind to study his social cognition abilities. Structural high-resolution magnetic resonance imaging showed bilateral hippocampal atrophy. The comparison to controls showed that, in addition to the well-documented memory disorders in developmental amnesia, BM showed remarkable deficits in 9 out of 17 social cognitive tasks assessing emotion recognition and theory of mind. In contrast, BM's performance on tasks of executive functions was largely preserved. The relevance of deficits in social cognition for patients with developmental amnesia is discussed.

Social cognition in epilepsy: State of the art and perspectives

INTRODUCTION

The neuropsychology of epilepsy has been a major area of study for almost a century and cognitive impairments are an integral part of the new definition of epilepsy. Among such impairments, social cognition (SC) dysfunctions are of relatively recent interest. SC abilities refer to the body of knowledge and processes involved in establishing satisfying and appropriate social interactions. In particular, they allow the recognition of emotions in others, emotional experiences which are suitably adapted to social situations, and the ability to infer mental states in oneself and others.

METHODS

An overeview was conducted of the available data within the literature, with the objective of presenting the SC disorders associated with certain types of epilepsy and the possible risk factors already explored i.e., localisation of epileptic focus, age of onset/duration of the disease, and effects of treatments including surgery. Studies investigating the potential repercussions of these disorders on patients' daily life have also been included.

RESULTS

Social cognition disorders are an integral part of the cognitive disorders traditionally described in epilepsy. Indeed, a growing number of studies highlight the increased prevalence of SC disorders in various domains, and some patients appear to be more at risk than others. These disorders could be a major determining factor in the deterioration of patients' quality of life (QOL), particularly patients' support and social integration. This highlights the importance of assessing and managing these disorders in patients with epilepsy (PWE). Perspectives in the field of research and clinical practice are also evoked, such as exploring the links between disruptions in SC abilities and treatments, or developing specific tools for assessment and rehabilitation within the context of epilepsy.

Social functioning and health-related quality of life trajectories in people with epilepsy after epilepsy surgery

OBJECTIVE

An improvement in quality of life (QoL) over time after epilepsy surgery has been demonstrated in people with epilepsy; however, social functioning has been less investigated. We conducted this study to examine whether postsurgical improvement is parallel between QoL and social functioning in patients with epilepsy.

METHODS

We retrospectively reviewed patients who underwent epilepsy surgery. All participants completed a comprehensive neuropsychological assessment, the Quality of Life in Epilepsy Inventory (QOLIE-89) questionnaire, and the Social and Occupational Functioning Scale for Epilepsy (SOFSE) before surgery and at 3 months, 6 months, and 1 year after surgery. Demographic and epilepsy-related information was also collected. Generalized estimating equations with identity links were used to model the QOLIE-89 and SOFSE over time and possible associated factors. A p < 0.05 was considered statistically significant.

RESULTS

A total of 76 patients, including 36 males and 43 females aged 18 to 62 years were collected. Both total QOLIE-89 and overall SOFSE improved over time after epilepsy surgery (adjusted p value < 0.001 and 0.002, respectively, with Bonferroni's correction). Total QOLIE-89 improved 3 months after surgery, while overall SOFSE showed no significant improvement until 6 months after surgery. The presurgical Full-Scale Intelligence Quotient (FSIQ) of the Wechsler Adult Intelligence Scale-III and years of education were significantly associated with time-dependent improvement for both total QOLIE-89 and overall SOFSE (p value < 0.001). At one year after surgery, overall SOFSE and total QOLIE-89 scores were significantly higher in the seizure-free group than in the nonseizure-free group (p value = 0.040 and 0.032, respectively).

CONCLUSION

Social functioning significantly improved in people with epilepsy after surgery as QoL, but it took more time to exhibit improvement. People with better FSIQ and more years of education had better improvement in social functioning over time. The early intervention of rehabilitation programs after epilepsy surgery might be necessary to facilitate the improvement in social functioning.

Social functions and socioeconomic vulnerability in epilepsy

Social functions are commonly impaired in people with epilepsy who are at increased risk of experiencing altered social cognition, communication problems, and interpersonal difficulties. Several factors are implicated, including developmental delay, seizure-related factors, somatic and psychiatric comorbidities, antiepileptic drugs (AEDs), and - not least - the effects of stigma. The variable interaction of all these factors can explain the differing pictures observed in the various epilepsy phenotypes but is also a source of interindividual variability depending on the strength of the effects of each factor on social cognition. This article is part of the Special Issue "Epilepsy and social cognition across the lifespan.

Social cognition and psychopathology in childhood and adolescence

There is a substantial body of research on social cognition in adults with epilepsy, and in broad categories such as focal and generalized epilepsies, but much less has been written about social cognition in children with epilepsy (CWE), and in childhood-onset epilepsy syndromes specifically. In several of these syndromes, autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD), two disorders with social cognitive impairments, are reported. There is strong evidence for social cognitive deficits in juvenile myoclonic epilepsy (JME). There is also a considerable amount of evidence for such deficits in a number of syndromes that may be associated with ASD or ADHD, including West syndrome (WS), Dravet syndrome (DS), and the Landau-Kleffner syndrome (LKS). However, the evidence is of variable quality and incomplete across the range of childhood epilepsy syndromes. In some syndromes, childhood epilepsy substantially increases the risk of severe social cognitive impairment, which may persist after the seizures remit. This paper presents an overview of current research on social cognition in childhood epilepsy, with a particular focus on syndromes with a high prevalence of autistic and behavioral comorbidities. Social cognitive impairments represent a considerable additional challenge for patients and caregivers. Early diagnosis and intervention might significantly improve long-term social cognitive outcomes, highlighting the need for greater awareness among clinicians of this important topic. This article is part of the Special Issue "Epilepsy and social cognition across the lifespan".

Hopelessness in persons with epilepsy: Relationship with demographic, clinical, and social variables

Persons with epilepsy show a higher risk of suicidal ideation and behavior than the general population. Hopelessness, as a feature of demoralization, is considered an emerging risk factor for suicidal ideation. Psychopathological comorbidity, mainly depression, has to be taken into account to predict suicidal attempts but the relationship between suicidality and epilepsy has been also reported independently from depressive disorders. The aim of the study was to investigate hopelessness in a sample of persons suffering from epilepsy without comorbidity with psychiatric disorders and its association with demographic, social, and clinical variables, putatively predictive of suicidal behaviors. Beck Hopelessness Scale (BHS) has been used as measure of suicidal ideation in 72 consecutive outpatients afferent to a third level epilepsy center. Exclusion criterion was psychiatric comorbidity evaluated by clinical approach and quantified by Clinical Global Impression (CGI) Scale. Clinical (focus localization, age at onset, number of drugs), demographic, social variables, and intellectual level were considered. Age, age at onset, gender, intellectual level, socioeconomic status, duration of illness and therapy, number of drugs, seizure frequency, and localization of the epileptic focus and side involved were found associated with BHS score increase. In a sample of persons with epilepsy, without psychiatric comorbidity, our data show an association between factors related to the biological pathophysiology and the clinical course of the disease with the sociodemographic status, as a risk factor for suicidal ideation.

Social cognition, psychiatric comorbidities, and quality of life in adults with epilepsy

Deficits in social cognition are an increasingly recognized complication of epilepsy and contribute to the deficits in social functioning and well-being experienced by patients with epilepsy. Although there has been an increase in studies exploring the measurement and biology of social cognition in patients with epilepsy, there are relatively few examining its clinical implications. Those studies that have been published highlight that social cognitive deficits contribute to impaired quality of life (QoL) in patients with epilepsy, independent of other comorbidities such as depression, anxiety, seizure frequency, and impairment in other cognitive domains. This raises the possibility of novel therapeutic approaches to improving the social well-being of patients with epilepsy.

Exploring the relationship between parent-child communication about epilepsy and psychosocial well-being

This study examined the relationship between parent-child communication and psychosocial well-being of 47 children living with epilepsy and 72 parents of children living with epilepsy. Open communication was associated with positive illness attitude, positive self-perception and greater health-related quality of life for children living with epilepsy; positive response to illness for parents; and more perceived social support and less need for epilepsy-related support for children living with epilepsy and parents. By contrast, closed communication was associated with poorer psychosocial well-being in children living with epilepsy and parents. Healthcare professionals should provide guidance for families living with childhood epilepsy on the importance of open communication in promoting greater psychosocial well-being.

Revisiting personality in epilepsy: Differentiation of personality in two epilepsies starting in adolescence

PURPOSE

The purpose of this study was to investigate personality characteristics and clinical parameters in two well-defined epilepsies: mesial temporal lobe epilepsy related to hippocampal sclerosis (MTLE/HS) and juvenile myoclonic epilepsy (JME) through NEO Revised Personality Inventory (NEO-PI-R) and Neurobehavior Inventory (NBI) standardized instruments.

METHODS

One hundred patients undergoing corticoamygdalohippocampectomy (CAH), 100 patients with JME, and 100 control subjects answered the personality measures. Clinical parameters such as psychiatric symptoms, seizure frequency, duration of epilepsy, and side of the lesion in MTLE/HS group were investigated. Statistical analysis consisted of the mean and standard deviation (SD) of each variable. Student's t-test or Fisher exact test were used according to the variable studied.

RESULTS

The three groups were within the average range of NEO-PI-R and NBI, although 'tendencies' and differences were demonstrated. The MTLE/HS and control subjects had a similar profile: low scores in Neuroticism and high in Conscientiousness (r = -0.330; p < 0.001/r = -0.567; p < 0.001, respectively) in opposition to what occurred in JME, low in Conscientiousness and high in Neuroticism (r = -0.509; p = 0.005). The NBI 'sense of personal destiny' trait was higher (3.15; p = 0.003) in MTLE/HS than in JME and controls. The JME 'law and order' scores were lower than in other groups (p = 0.024). A tendency towards specific NBI traits differentiates MTLE/HS (Factor 3) from JME (Factor 1) groups. Psychiatric symptoms and seizure frequency were correlated with worse scores in NBI and, especially, in Neuroticism domain of NEO-PI-R.

CONCLUSION

Specific personality features were linked to each epileptic disease. These findings highlight the importance of considering unique features linked to epilepsy conditions in daily clinical observation to develop support programmes.

Challenges in epilepsy-The perspective of Norwegian epilepsy patients

OBJECTIVES

For most people with epilepsy (PWE), problems that are not directly related to seizures may constitute major challenges in everyday life. The purpose of this study was to determine the extent of these challenges and any risk factors for their occurrence among PWE in Norway, based on the patients' own perspective.

MATERIALS AND METHODS

We used a web-based survey to ask PWE visiting the homepage of the Norwegian Epilepsy Association about different everyday challenges. A link to the survey was accessible via the members' homepage for a 4-month period during 2017.

RESULTS

One thousand one hundred eighty-two PWE responded to the questionnaire. Although more than 40% of the cohort reported that they had been seizure free for at least 1 year, the majority reported that tiredness (71%), memory problems (70%), concentration problems (68%), headache or vertigo (51%), and feeling depressed (59%) continued to represent challenges. In addition, fear of being alone, sexual problems or difficulties in social settings were reported by about one-third of the patients. Reporting having these challenges was significantly associated with female gender, polytherapy, experiencing seizures during the previous 12 months and feeling blue or depressed.

CONCLUSIONS

The results of this study, reflecting a self-selected Norwegian population, provide insights into the challenges not directly associated with seizures that impact on the quality of life of PWE. The impacts of such challenges may be underestimated as components of the entire burden of epilepsy.
