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

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.

Bibliometric analysis of research in epilepsy and comorbid depression from 2014 to 2023

BACKGROUND

Epilepsy and depression have complicated bidirectional relationships. Our study aimed to explore the field of epilepsy comorbid with depression in a bibliometric perspective from 2014-2023.

AIM

To improve our understanding of epilepsy and depression by evaluating the relationship between epilepsy and depression, bibliometric analyses were performed.

METHODS

Epilepsy and depression-related publications from the last decade were retrieved from the Web of Science Core Collection. We conducted bibliometric and visual analysis using VOSviewer and CiteSpace, examining authorships, countries, institutions, journals of publication, co-citations of references, connections between keywords, clusters of keywords, and keywords with citation bursts.

RESULTS

Over the past ten years, we collected 1045 research papers focusing on the field of epilepsy and comorbid depression. Publications on epilepsy and depression have shown a general upward trend over time, though with some fluctuations. The United States, with 287 articles, and the University of Melbourne, contributing 34 articles, were the top countries and institutions, respectively. In addition, in the field of epilepsy and depression, Professor Lee, who has published 30 articles, was the most contributing author. The hot topics pay attention to the quality of life in patients with epilepsy and depression.

CONCLUSION

We reported that quality of life and stigma in patients with epilepsy comorbid with depression are possible future hot topics and directions in the field of epilepsy and depression research.

Effects of a Nurse-Led Cognitive Behavioral Intervention for Parents of Children With Epilepsy

BACKGROUND

This study aimed to evaluate the effects of a nurse-led cognitive behavioral intervention for parents of children with epilepsy (CWE).

METHODS

The study recruited 238 CWE from the neurology ward of Xiangya Hospital from March 2019 to August 2022. According to the interventions after discharge, the children and their parents were randomly divided into 117 parent-child dyads in the intervention group and 121 parent-child dyads in the control group. The seizure severity and treatment compliance in CWE as well as the parents' psychological states and satisfaction with the care provided by nurses were compared before and after intervention.

RESULTS

The follow-up six months after discharge showed that the seizure frequency among CWE in the intervention group was significantly less than the controls (P = 0.048). Compared with the controls, the intervention group also reported fewer symptoms of anxiety and depression, better sleep quality, and more positive attitudes toward epilepsy, as well as higher nursing satisfaction (P < 0.001). The correlation analysis indicated the correlation of CWE's seizure severity was correlated with the compliance, parents' psychological states, and parents' satisfaction with the care provided by nurses.

CONCLUSIONS

The adoption of the nurse-led cognitive behavioral intervention on parents of CWE can improve the parents' mental health status and their satisfaction with the nurses, which can have a positive association with the seizure severity of CWE. In light of this information, this nursing intervention may be a new method for the long-term disease management of CWE.

Social cognition in adult survivors of brain tumors: studying the relationship between theory of mind and quality of life

OBJECTIVE

The present study is the first to examine theory of mind (ToM) sequelae in a sample of adult survivors of primary brain tumors, and to investigate the assumed relationship between ToM and health-related quality of life (HRQoL).

METHOD

Participants were 40 long-term adult survivors of primary brain tumors and 40 matched healthy controls. They completed ToM tests (Faux-Pas test and Advanced ToM task) and two questionnaires assessing HRQoL (36-Item Short-Form Health Survey and EORTC QLQ-C30/QLQ-BN20). Their relatives also completed an observer-rated version of the SF-36 questionnaire.

RESULTS

Survivors performed worse than controls only on the Advanced ToM task. Overall, patients and caregivers reported more problems than healthy controls and their relatives regarding both global HRQoL and its social/emotional aspects. No relationship was found between ToM and HRQoL scores.

CONCLUSION

Adult survivors of primary brain tumors may exhibit ToM deficits several years after treatment and report more problems on social/emotional HRQoL components. Our findings highlight the need to consider these late effects in survivors' long-term follow-up, even if the clinical involvement of ToM deficits still needs to be elucidated. The assessment of ToM deficits and their potential impact on survivors' everyday life is thoroughly discussed.

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.

Social Cognition and Functioning in Patients With Social Anxiety Disorder and/or Attention-Deficit/Hyperactivity Disorder

ABSTRACT

In recent years, social cognition and one of its dimensions, the theory of mind, have been more commonly investigated in patients with social anxiety disorder (SAD) and attention-deficit/hyperactivity disorder (ADHD). In this study, SAD, ADHD, comorbid SAD-ADHD, and healthy control (HC) groups, each consisting of 30 participants, were included and compared in terms of social cognition and functionality. Mean global functioning assessment scores were found to be significantly higher in the HC group compared with the other three groups and in the ADHD group compared with the SAD and SAD-ADHD groups. Mean Dokuz Eylül Theory of Mind Index total scores were found to be significantly higher in the HC group compared with the other three groups and in the SAD and SAD-ADHD groups compared with the ADHD group. These findings suggest that SAD patients with or without ADHD show better social cognition but worse functioning compared with pure ADHD patients.

Epilepsy Videos on YouTube: A Cross-Sectional Observational Study

INTRODUCTION

Epilepsy is defined as a disorder of the brain characterized by an enduring predisposition to epileptic seizures. Being the most common neurological condition in the world, information regarding epilepsy is gathered by people from different available sources.

OBJECTIVES

The objective of this study was to evaluate the reliability and quality of YouTube videos about epilepsy as a source of information for the general population and also for patients suffering from this illness and for their families.

METHODOLOGY

A cross-sectional observational study was conducted, utilizing a questionnaire prepared on Google Forms (Google LLC, Mountain View, California, United States) with predetermined criteria. Each of the six authors independently searched and evaluated 10 YouTube videos using specific keywords. The assessment included determining the global quality score and utilizing the DISCERN tool. The collected data was recorded in Microsoft Excel and subsequently analyzed.

RESULTS

A total of 60 videos were analyzed, revealing that 76.27% of them provided information on the available treatment options for epilepsy, 71.19% explained the cause and etiology of the condition, and only 3.39% of the videos mentioned support groups.

CONCLUSIONS

Our study highlights the importance of assessment of medical information on social media platforms in order to ensure availability of correct information with high quality and reliability for epilepsy patients. This will help in understanding their medical health issues and decision making.

Social Cognition in Temporal and Frontal Lobe Epilepsy: Systematic Review, Meta-analysis, and Clinical Recommendations

OBJECTIVE

Despite the importance of social cognitive functions to mental health and social adjustment, examination of these functions is absent in routine assessment of epilepsy patients. Thus, this review aims to provide a comprehensive overview of the literature on four major aspects of social cognition among temporal and frontal lobe epilepsy, which is a critical step toward designing new interventions.

METHOD

Papers from 1990 to 2021 were reviewed and examined for inclusion in this study. After the deduplication process, a systematic review and meta-analysis of 44 and 40 articles, respectively, involving 113 people with frontal lobe epilepsy and 1482 people with temporal lobe epilepsy were conducted.

RESULTS

Our results indicated that while patients with frontal or temporal lobe epilepsy have difficulties in all aspects of social cognition relative to nonclinical controls, the effect sizes were larger for theory of mind (g = .95), than for emotion recognition (g = .69) among temporal lobe epilepsy group. The frontal lobe epilepsy group exhibited significantly greater impairment in emotion recognition compared to temporal lobe. Additionally, people with right temporal lobe epilepsy (g =  1.10) performed more poorly than those with a left-sided (g = .90) seizure focus, specifically in the theory of mind domain.

CONCLUSIONS

These data point to a potentially important difference in the severity of deficits within the emotion recognition and theory of mind abilities depending on the laterlization of seizure side. We also suggest a guide for the assessment of impairments in social cognition that can be integrated into multidisciplinary clinical evaluation for people with epilepsy.

Fighting Epilepsy with Nanomedicines-Is This the Right Weapon?

Epilepsy is a chronic and complex condition and is one of the most common neurological diseases, affecting about 50 million people worldwide. Pharmacological therapy has been, and is likely to remain, the main treatment approach for this disease. Although a large number of new antiseizure drugs (ASDs) has been introduced into the market in the last few years, many patients suffer from uncontrolled seizures, demanding the development of more effective therapies. Nanomedicines have emerged as a promising approach to deliver drugs to the brain, potentiating their therapeutic index. Moreover, nanomedicine has applied the knowledge of nanoscience, not only in disease treatment but also in prevention and diagnosis. In the current review, the general features and therapeutic management of epilepsy will be addressed, as well as the main barriers to overcome to obtain better antiseizure therapies. Furthermore, the role of nanomedicines as a valuable tool to selectively deliver drugs will be discussed, considering the ability of nanocarriers to deal with the less favourable physical-chemical properties of some ASDs, enhance their brain penetration, reduce the adverse effects, and circumvent the concerning drug resistance.

People with epilepsy have poor life satisfaction and self-rated health: Findings from the United Kingdom

Epilepsy is a neurological disorder characterized by brief, recurrent disturbances in the normal electrical functions of the brain that result in seizures. Although epilepsy is closely related to wellbeing, much less is known about how life satisfaction and SRH are affected by epilepsy in a nationally representative sample from the United Kingdom. The current research aims to investigate the difference in life satisfaction and SRH between people with epilepsy and people without epilepsy by using an innovative train-and-test approach on data collected between 2009 and 2010 from 428 people with epilepsy and 39,024 healthy controls while taking demographics into account. The results showed that people with epilepsy have both poorer life satisfaction and SRH compared to the scores that would be predicted by their demographics. This study implies that both life satisfaction and SRH are valid measures of wellbeing in people with epilepsy. Health professionals may utilize findings from the current study to come up with ways that can benefit wellbeing of people with epilepsy.

Emotion recognition dysfunction after anesthesia and cardiac surgery

Cognitive dysfunction after anesthesia and surgery has long been recognized. Recently, researchers provided empirical evidence for social cognition dysfunction (SCD) after anesthesia and surgery. In the present study, we concentrated on the deficits in emotion recognition, one of the most important clinical perspectives in SCD, in patients who underwent cardiac surgery. Biological motion (BM) was considered as the stimulus of interest, and patients' abilities of BM emotion perception and action perception before and after anesthesia and surgery were examined. In total, 60 adult patients (40-72 years old) completed the BM recognition task, which required them to label the types of actions and emotions of perceived BM. The results showed that while action perception remained intact after cardiac surgery, 18.3% of patients exhibited deficits in emotion perception, further confirming the existence of SCD after anesthesia and surgery.

Eine Lücke, die es zu schließen gilt: Die Untersuchung sozial-kognitiver Fähigkeiten an deutschsprachigen Memory-Kliniken

Zusammenfassung: Die Untersuchung sozial-kognitiver Fähigkeiten kann zur Diagnostik kognitiver Störungen beitragen. In diesem Zusammenhang stellt sich die Frage, inwieweit sozial-kognitive Fähigkeiten in deutschsprachigen Memory-Kliniken (MK) untersucht werden. Wir führten dazu eine Befragung in 87 deutschsprachigen MK in Deutschland, österreich und der Schweiz durch. Es zeigte sich, dass die Untersuchung sozial-kognitiver Fähigkeiten mehrheitlich befürwortet wird, jedoch nur selten erfolgt. Die Mehrheit der MK könnte sich jedoch vorstellen, in Zukunft sozial-kognitive Diagnostik durchzuführen, vorausgesetzt, dass hierfür adäquate psychometrische Testverfahren vorliegen. Die Forderung der MK nach psychometrischen sozial-kognitiven Tests gewinnt an Bedeutung angesichts der Tatsache, dass die kürzlich publizierten ICD-11-Kriterien (International Statistical Classification of Diseases and Related Health Problems) die Untersuchung sozial-kognitiver Fähigkeiten bei der Abklärung einer kognitiven Störung empfehlen.

Progression of socio-cognitive impairment from healthy aging to Alzheimer's Dementia: A systematic Review and Meta-Analysis

BACKGROUND

Trajectories of decline across different socio-cognitive domains in healthy older adults and in pathological aging conditions have not been investigated. This was addressed in the present systematic review and meta-analysis.

METHODS

MEDLINE, Web of Science Core Collection, CENTRAL, and PsycInfo were searched for studies investigating social cognition across four domains (Theory of Mind, ToM; emotion recognition, ER; Social-decision making, SD; visual perspective taking, VPT) in healthy older individuals, individuals with subjective and mild cognitive impairment (SCD, MCI) and Alzheimer's disease (AD). Random-effects meta-analyses were conducted.

RESULTS

Of 8,137 screened studies, 132 studies were included in the review. ToM and ER showed a clear progression of impairment from normal aging to AD. Differential patterns of decline were identified for different types of ToM and ER.

CONCLUSION

This systematic review identified progression of impairment of specific socio-cognitive abilities, which is the necessary pre-requisite for developing targeted interventions. We identified a lack of research on socio-cognitive decline in different populations (e.g., middle age, SCD and MCI-subtypes) and domains (SDM, VPT).

Efficacy comparison of oxcarbazepine and levetiracetam monotherapy among patients with newly diagnosed focal epilepsy in China: A multicenter, open-label, randomized study

Aims

This multicenter, open‐label, randomized study (Registration No. ChiCTR‐OCH‐14004528) aimed to compare the efficacy and effects of oxcarbazepine (OXC) with levetiracetam (LEV) as monotherapies on patient quality of life and mental health for patients with newly diagnosed focal epilepsy from China.

Methods

Patients with newly diagnosed focal epilepsy who had experienced 2 or more unprovoked seizures at greater than a 24‐h interval during the previous year were recruited. Participants were randomly assigned to the OXC group or LEV group. Efficacy, safety, quality of life, and mental health were evaluated over 12‐week and 24‐week periods.

Results

In total, we recruited 271 newly diagnosed patients from 23 centers. Forty‐four patients were excluded before treatment for reasons. The rate of seizure freedom of OXC was significantly superior to that of LEV at 12 weeks and 24 weeks (p < 0.05). The quality of life (except for the seizure worry subsection) and anxiety scale scores also showed significant differences from before to after treatment in the OXC and LEV groups.

Conclusions

OXC monotherapy may be more effective than LEV monotherapy in patients with newly diagnosed focal epilepsy. Both OXC and LEV could improve the quality of life and anxiety state in adult patients with focal epilepsy.

Mechanisms Underlying Aquaporin-4 Subcellular Mislocalization in Epilepsy

Epilepsy is a chronic brain disorder characterized by unprovoked seizures. Mechanisms underlying seizure activity have been intensely investigated. Alterations in astrocytic channels and transporters have shown to be a critical player in seizure generation and epileptogenesis. One key protein involved in such processes is the astrocyte water channel aquaporin-4 (AQP4). Studies have revealed that perivascular AQP4 redistributes away from astrocyte endfeet and toward the neuropil in both clinical and preclinical studies. This subcellular mislocalization significantly impacts neuronal hyperexcitability and understanding how AQP4 becomes dysregulated in epilepsy is beginning to emerge. In this review, we evaluate the role of AQP4 dysregulation and mislocalization in epilepsy.

Psychiatric Comorbidities in Epilepsy

BACKGROUND AND PURPOSE

Psychiatric comorbidities (PC) occur more frequently in patients with epilepsy than in the general population. To determine the main PC associated with epilepsy and its association with demographic data and clinical features of epilepsy.

METHODS

A retrospective study was carried out on patients with epilepsy at the Medical Specialties Center of the Municipal Health Department. Demographic data, crisis onset, time range of seizures evolution, type of epileptic seizures, types of epilepsy, etiology, brain injury, topographic location, hemispheric location, type of antiepileptic drugs (AEDs), use of monotherapy or polytherapy, control of epileptic seizures and the PC were recorded.

RESULTS

One hundred forty adult patients were studied 51.4% male, mean age 44.9 years, time of evolution of the crises was 14 years, focal crisis 88.6%, mesial temporal sclerosis 42%, controlled 92.4%, monotherapy 66.1%, and the most used AEDs were carbamazepine (33.1%), valproic acid (28.2%), and phenobarbital (10.4%). The PC present in 67.1% of the patients was depression (22.8%), anxiety disorder (AD) (17.8%), psychosis (10%), dementia (9.2%) and bipolar affective disorder (BAD) (8.5%). The relationship between PC and crisis control was significant (p<0.009).

CONCLUSIONS

Schooling was lower than that reported in the general population in Brazil, and we found a low rate of unemployment or retirement. Epilepsy is associated with PC, the most frequent being depression, AD, psychosis, dementia and BAD. The absence of a relationship between depression and brain damage; anxiety disorder with education, types of epilepsy and etiology; psychosis with sex and time of epilepsy evolution were significant.

Memory and executive functioning outcomes of selective amygdalohippocampectomy in patients with hippocampal sclerosis: A preliminary study in a developing country

Background

Selective amygdalohippocampectomy (SA) is an effective treatment for drug-resistant cases of epilepsy due to hippocampal sclerosis (HS). However, its neurocognitive outcomes are inconsistent across the previous studies, pointing to potential location-specific confounders. Here, we investigated the neurocognitive outcomes of SA in an Iranian center recently adopting this approach.

Methods

Thirty adults (53.3% of females, age 31.4 ± 6.2 years) with drug-resistant epilepsy due to HS were included in the study. Patients were stratified into surgical (n = 15) and medical (n = 15) treatment groups based on their preferences. Neurocognitive function was assessed before and 6 months after intervention using Wisconsin Card Sorting Test (WCST), Wechsler Adult Intelligence Scale-Revised, and Wechsler Memory Scale- Third Edition (WMS-III). Postintervention performance changes were compared between the two groups, and predictors of worse postoperative outcomes were investigated.

Results

Longitudinal changes of performance in WMS-III and WCST were significantly different between the surgically and medically treated patients. Postoperative WMS-III performance showed an average 25% decline (mean ∆T2-T1 = -25.1%, T = -6.6, P < 0.001), and WCST performance improved by an average of 49% (mean ∆T2-T1 = +49.1%, T = 4.6, P < 0.001). The decline in memory performance was more severe in the left-sided surgery and in patients with higher baseline education (mean ∆T2-T1 = -31.1%, T = -8.9, P < 0.001).

Conclusion

In our center, executive functioning improved or remained stable after SA, but memory functions declined moderately. The left-sided SA and higher education were associated with more severe decline in memory functions, highlighting the need for special considerations for these groups.

Social Isolation and Associated Factors in Chinese Adults With Epilepsy: A Cross-Sectional Study

Objective: We aimed to determine the prevalence of social isolation and associated factors among adults with epilepsy in northeast China. Methods: A cohort of consecutive patients with epilepsy (PWE) from the First Hospital of Jilin University (Changchun, China) was recruited. Demographic and clinical data for each patient were collected during a face-to-face interview. Social isolation was measured using the Berkman-Syme Social Network Index (SNI), and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) and Quality of Life in Epilepsy Inventory (QOLIE-31) were also administered. Multivariate logistic regression analyses were used to determine the factors associated with social isolation in PWE. Results: A total of 165 patients were included in the final analysis. The mean SNI score was 2.56 (SD: 1.19), and 35 patients (21.2%) were socially isolated. In multivariate logistic regression analysis, higher depressive symptom levels (OR = 1.15, 95% CI: 1.003-1.318, P = 0.045) and poorer quality of life (OR = 0.967, 95% CI: 0.935-0.999, P = 0.047) emerged as independent factors associated with social isolation in PWE. Conclusion: Social isolation is common and occurs in approximately one-fifth of PWE. Social isolation is significantly associated with depressive symptoms and poor quality of life in PWE. Patients need to be encouraged to actively integrate with others and reduce social isolation, which may help improve their quality of life.

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.

Associations between socioemotional alterations, quality of life, and social functioning in multiple sclerosis: A scoping review

The main aim of the present scoping review is to systematically review the available studies that investigated the associations between socioemotional alterations (i.e., social cognition impairments/alexithymia/difficulties in emotion regulation) and both reduced QoL and social functioning in patients with Multiple Sclerosis (MS). The articles were selected from the PubMed, PsycINFO, and Scopus databases. The main exclusion criteria were qualitative studies, articles that did not use validated instruments, and studies that did not investigate the association between socioemotional skills and QoL/social functioning in MS. Of the eight studies fulfilling the inclusion criteria, six found significant associations between social cognitive and emotion regulation abilities and QoL/social functioning in patients with MS, while two found no significant relationships particularly between the performance on social cognition tasks and QoL measures. Overall, the majority of findings seem to highlight that socioemotional alterations contribute to impaired QoL and social functioning in MS. However, given the still limited evidence, future studies are needed to replicate and confirm the available results, paying attention to two principal aspects: the use of standardized and ecological tasks for the assessment of social cognition skills and the recruitment of samples involving patients with different types of MS.

Theory of mind and its neuroanatomical correlates in people with multiple sclerosis

Background Theory of mind (ToM) is one of the several different concepts in social cognition and is defined as the ability to access the mental states of others or to adopt the point of view of others. Although studies have shown that ToM is impaired in people with multiple sclerosis (MS), the results based on individual ToM tasks are conflicting; some studies have shown deficits only in the 'Reading the Mind in the Eyes' Test (RMET), while others have reported poor performance in the Faux Pas Test (FPT) as well as RMET. Furthermore, little is known about the relationship between ToM performance and neuroanatomical characteristics in MS. This study investigated ToM impairment and its relationship to regional brain volume or cortical thickness in people with MS. Methods This cross-sectional study included 20 participants with relapse-onset MS and 27 age- and sex-matched volunteers as healthy controls (HC). All the participants underwent neuropsychological (NP) tests as well as ToM tasks, including RMET and FPT. Participants with MS underwent brain MRI within 6 months before and after undergoing the NP and ToM tests. Regional volume of subcortical structures or cortical thickness were analysed based on 3D T1-weighted images using FreeSurfer software. Results Both RMET and FPT scores were significantly lower in participants with MS than in HC (p = 0.0049, p = 0.0071, respectively). Imaging analyses showed that FPT scores, but not RMET scores, were positively correlated with the right thalamus (R² = 0.26, p = 0.012) and left pallidum (R² = 0.39, p = 0.0021) volumes after adjusting for age. Furthermore, surface-based morphometry revealed significant correlation between age-adjusted cortical thickness of ten cortical areas, including the fusiform gyrus, orbitofrontal cortex, temporal-parietal junction, and superior temporal gyrus, and FPT scores. Conclusions These study findings showed that both RMET and FPT performances are impaired in participants with MS. Furthermore, FPT deficits, but not RMET deficits, were significantly associated with the volume of two subcortical structures as well as the thickness of ten cortical areas, suggesting that FPT is an appropriate task to access ToM performance in MS.

Validation of the Health-Related Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) for Brazilian Portuguese

OBJECTIVE

The present study aimed to validate the 55-item Health-Related Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) in Brazilian Portuguese and evaluate the relation of its results with clinical data and caregiver burden.

METHODS

The QOLCE-55 was submitted to translation, back-translation, and cultural adaptation in a pilot sample with 20 subjects. To ensure the psychometric properties of validation, the validation of the QOLCE-55 was carried out in a sample of 45 patients with epilepsy aged between 4 and 18 years and their parents or caregivers and compared with the results of other quality-of-life instruments, namely, the QVCE-50 and QOLIE-AD-48, as well as with the SDQ, abrief behavioral screeningquestionnaire. The WASI and SON-R 2½-7 [a] were used for evaluation of intelligence quotient (IQ) and the Burden Interview for the caregiver burden.

RESULTS

Internal consistency measured by Cronbach's alpha coefficient was moderate (0.692; p = 0.264), and the test-retest reliability analyzed by the intraclass correlation coefficient was satisfactory when compared with the results by different examiners on the same day (0.951; p = 0.001) and at different times (0.778; p = 0.001). This version of the QOLCE-55 presented a strong correlation with the QVCE-50 (0.904; p < 0.001) and SDQ (-0.428; p = 0.004) but a low correlation with the QOLIE-AD-48 (0.094; p = 0.729). This version also presented a correlation with IQ (R = 0.456, p = 0.003) and an inverse correlation with the Burden Interview (-0.390; p = 0.012). Low quality of life was associated with the presence of tonic-clonic seizures (p = 0.005), polytherapy (p = 0.003), and low socioeconomic conditions (p = 0.005).

CONCLUSIONS

The Brazilian Portuguese version of the QOLCE-55 was confirmed as a reliable and valid scale to assess quality of life in children and adolescents with epilepsy. Behavioral problems, caregiver burden, tonic-clonic seizures, polytherapy, and socioeconomic precariousness were associated with low quality-of-life values, while IQ was positively correlated with the quality of life in this population.

Social brain networks: Resting-state and task-based connectivity in youth with and without epilepsy

Individuals with epilepsy often experience social difficulties and deficits in social cognition. It remains unknown how disruptions to neural networks underlying such skills may contribute to this clinical phenotype. The current study compared the organization of relevant brain circuits-the "mentalizing network" and a salience-related network centered on the amygdala-in youth with and without epilepsy. Functional connectivity between the nodes of these networks was assessed, both at rest and during engagement in a social cognitive task (facial emotion recognition), using functional magnetic resonance imaging. There were no group differences in resting-state connectivity within either neural network. In contrast, youth with epilepsy showed comparatively lower connectivity between the left posterior superior temporal sulcus and the medial prefrontal cortex-but greater connectivity within the left temporal lobe-when viewing faces in the task. These findings suggest that the organization of a mentalizing network underpinning social cognition may be disrupted in youth with epilepsy, though differences in connectivity within this circuit may shift depending on task demands. Our results highlight the importance of considering functional task-based engagement of neural systems in characterizations of network dysfunction in epilepsy.

Telemedicine during the SARS-Cov-2 pandemic lockdown: Monitoring stress and quality of sleep in patients with epilepsy

SARS-CoV-2 pandemic heavily hit the western healthcare system saturating the hospital beds in wards and clogging the emergency departments. To avoid the collapse of Italian hospitals, office visits to outpatients were limited to emergencies and the general population went in a lockdown state. Physicians had to approach new problems in the management of chronic patients who could not leave their homes. In our experience as epilepsy clinic, the use of telemedicine was of crucial importance for monitoring our patients: phone call during lockdown let us monitor the stability of our 38 patients and psychometric parameters and habits that could influence seizures frequency. In particular, we found that in our patients, sleep quality was low resulting in high daily sleepiness and associated high stress levels. Secondly, we found an increase in daily screen hours and an association with daily sleepiness. In conclusion, we report our experience in managing people with epilepsy during the lockdown, underlining the utility of telemedicine as a valid monitoring tool and the necessity of a psychometric and behavioral screening.

Effect of add-on melatonin on seizure outcome, neuronal damage, oxidative stress, and quality of life in generalized epilepsy with generalized onset motor seizures in adults: A randomized controlled trial

Epilepsy treatment is challenging because of multiple impediments like lack of efficacy of monotherapy, adverse drug reactions, and different comorbidities. Add-on therapy to first-line antiepileptics may be the option to overcome therapeutic hurdles. The present randomized, double-blind, add-on placebo-controlled clinical trial was conducted to evaluate the effect of add-on melatonin in the treatment of generalized epilepsy with generalized onset motor seizure in adults. The control group (n = 52) received add-on placebo, and the test group (n = 52) received add-on melatonin (3 mg/day) with valproate (20 mg/kg in two divided doses). Clinical evaluation of seizure frequency, Chalfont-National Hospital seizure severity scale (NHS3), Pittsburgh sleep quality index (PSQI), quality of life in epilepsy inventory, Epworth sleepiness scale (ESS), and biochemical estimation of serum neuron-specific enolase (NSE) and glutathione reductase were done at baseline and compared with follow-up at 8 weeks. Among 104 patients randomized [mean (SD) age of 27.6 (11.5); 84 (80.8%) male], 88 (84.6%) completed the trial. The responder rate and seizure-free rate in the test group were significantly (p = 0.006 and 0.034) higher than the control group. There was a significantly higher reduction in the frequency of seizures (p = 0.016) and NHS3 (-2.39; 95%CI: -4.56 to -0.21; p = 0.032) in the test group compared to the control group. Similarly, improvement in PSQI (-1.40; 95%CI: -2.64 to -0.15; p = 0.029) was significantly better in the test group. There was no significant difference in the change in ESS (p = 0.621) and quality of life scoring (p = 0.456) between the study groups. The decrease in serum NSE was significantly higher with the test group compared to the control group (-2.01; 95% CI: -3.74 to -0.27; p = 0.024). Add-on melatonin increased serum glutathione reductase significantly (p = 0.038), but there was no significant difference between the groups (p = 0.685). Add-on melatonin with valproate for generalized epilepsy with generalized onset motor seizures in adults can achieve a significantly better clinical outcome by reducing the seizure frequency, severity and attaining a better seizure-free rate in comparison to the control group.

Targeted Reducing of Tauopathy Alleviates Epileptic Seizures and Spatial Memory Impairment in an Optogenetically Inducible Mouse Model of Epilepsy

Intracellular deposition of hyperphosphorylated tau has been reported in the brain of epilepsy patients, but its contribution to epileptic seizures and the association with spatial cognitive functions remain unclear. Here, we found that repeated optogenetic stimulation of the excitatory neurons in ventral hippocampal CA1 subset could induce a controllable epileptic seizure in mice. Simultaneously, the mice showed spatial learning and memory deficits with a prominently elevated total tau and phospho-tau levels in the brain. Importantly, selective facilitating tau degradation by using a novel designed proteolysis-targeting chimera named C4 could effectively ameliorate the epileptic seizures with remarkable restoration of neuronal firing activities and improvement of spatial learning and memory functions. These results confirm that abnormal tau accumulation plays a pivotal role in the epileptic seizures and the epilepsy-associated spatial memory impairments, which provides new molecular target for the therapeutics.

Alterations of Neuronal Dynamics as a Mechanism for Cognitive Impairment in Epilepsy

Epilepsy is commonly associated with cognitive and behavioral deficits that dramatically affect the quality of life of patients. In order to identify novel therapeutic strategies aimed at reducing these deficits, it is critical first to understand the mechanisms leading to cognitive impairments in epilepsy. Traditionally, seizures and epileptiform activity in addition to neuronal injury have been considered to be the most significant contributors to cognitive dysfunction. In this review we however highlight the role of a new mechanism: alterations of neuronal dynamics, i.e. the timing at which neurons and networks receive and process neural information. These alterations, caused by the underlying etiologies of epilepsy syndromes, are observed in both animal models and patients in the form of abnormal oscillation patterns in unit firing, local field potentials, and electroencephalogram (EEG). Evidence suggests that such mechanisms significantly contribute to cognitive impairment in epilepsy, independently of seizures and interictal epileptiform activity. Therefore, therapeutic strategies directly targeting neuronal dynamics rather than seizure reduction may significantly benefit the quality of life of patients.

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.

Social Cognitive Dysfunction in Elderly Patients After Anesthesia and Surgery

Extensive studies have revealed that cognitive processing was impaired after anesthesia and surgery, particularly for the elderly patients. However, most of the existing studies focused on the general cognitive deficits (e.g., delayed neuro-cognitive recovery and POCD). Although diagnosis of social abilities has been used in various clinical fields, few studies have investigated the potential deficit on social cognition after anesthesia and surgery. The current study examined whether there was any social cognitive dysfunction after anesthesia and surgery. We achieved this by taking biological motion (BM) as the stimuli of interest, the perception of which has been taken as the hallmark of social cognition. The elderly patients (aged ≥ 60 years) were required to judge whether an upright BM stimulus appeared among the dynamic noises to test their social cognition, as well as do a Mini-Mental State Examination to test their general cognition. The two tests were performed at both 1-day before and 7-day after the surgery. Results showed that 31.25% of patients exhibited BM perception deficit after anesthesia and surgery relative to before anesthesia and surgery, implying that social cognitive dysfunction existed. Meanwhile, social cognitive dysfunction was independent from delayed neurocognitive recovery.

Medication burden in epilepsy: Exploring the impact of non-epilepsy concomitant drugs load

PURPOSE

To determine the burden of non-epilepsy drugs on people with epilepsy, using administrative health care data.

METHODS

The Achmea Health Insurance Database (AHID) contains health claims data from 25 % of the Dutch population. From the AHID, we selected all policyholders with coverage for at least one full calendar year between 2006-2009. We included adults with diagnostic codes for epilepsy and randomly selected two frequency-matched controls per case. We labeled drugs dispensed at least twice per calendar year as chronic and excluded antiseizure medications. We estimated and compared the prevalence of chronic medication use, number of chronic medications used, number of prescriptions dispensed, Rx Risk comorbidity index, and drug burden index (DBI) between people with epilepsy and controls.

RESULTS

Non-epilepsy chronic medication use was more frequent in people with epilepsy than controls (67 % versus 59 %, p < 0.001). People with epilepsy had an increased DBI (average 0.19 versus 0.10, p < 0.001), used more chronic medications (median 2 versus 1, p < 0.001) and had more prescriptions dispensed (median 7 versus 3, p < 0.001). The DBI and number of unique chronic medications were higher among older (>60 years) than younger (<60 years) subjects in cases and controls. Non-epilepsy chronic medication use was more prevalent in people with epilepsy across all therapeutic drug classes and most comorbidities measured using the Rx Risk score.

CONCLUSION

Chronic non-epilepsy medication use is more prevalent among people with epilepsy. The medication burden is higher among elderly with epilepsy and could partially explain the lower quality of life of people with epilepsy with comorbidities.

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.

Independent contributions of social cognition and depression to functional status after moderate or severe traumatic brain injury

Impairments in cognitive processing related to social understanding and communication (i.e., "social cognition") are well documented after moderate or severe traumatic brain injury (TBI) and can contribute to negative functional outcome. Depression is also a common feature of TBI with detrimental functional consequences. We evaluated relationships between social cognition, depression symptom severity, and functional status in individuals with chronic TBI (>1 year post injury; n = 25) and healthy controls (n = 30) using objective tests of social cognition as well as self-reported depression (Beck Depression Inventory-II) and functional status (Functional Behavior Profile). Results revealed significant relationships between depression and functional status across the sample, and relationships between social cognition and functional status specific to TBI. In the TBI group only, social cognition significantly predicted both overall and social functional status above and beyond depression. Group differences in functional status were independently mediated by social cognition and, especially, depression. Our findings suggest that social cognitive impairments and depression are distinct, functionally relevant TBI sequelae. Interventions to improve social functioning in this population may be most effective when contextualized within treatments for emotional disturbances.

Pharmacological Management of the Genetic Generalised Epilepsies in Adolescents and Adults

Common genetic generalised epilepsy syndromes encountered by clinicians include childhood and juvenile absence epilepsies, juvenile myoclonic epilepsy and generalised tonic-clonic seizures on awakening. Treatment of these syndromes involves largely the use of broad-spectrum antiseizure drugs. Those effective for the generalised epilepsies include sodium valproate, phenobarbital, ethosuximide, clobazam, clonazepam, lamotrigine, levetiracetam, topiramate, zonisamide and, more recently, perampanel and brivaracetam. Results from the few rigorous studies comparing outcomes with drugs for genetic generalised epilepsies show valproate to be the most effective. The majority of patients with genetic generalised epilepsy syndromes will become seizure free on antiseizure monotherapy; those for whom control proves elusive may benefit from combination regimens. Early counselling regarding management may assist the patient to come to terms with their diagnosis and improve long-term outcomes. Treatment can be lifelong in some individuals, although others may remain seizure free without medication. Choice of antiseizure medication depends on the efficacy for specific seizure types, as well as tolerability. For patients prescribed comedication, drug interactions should be considered. In particular, for young women taking oral hormonal contraceptives, ≥ 200 mg/day of topiramate can decrease the circulating concentration of ethinylestradiol and ≥ 12 mg/day of perampanel can induce levonorgestrel metabolism. The use of valproate in women of childbearing potential is limited by associated teratogenic and neurodevelopmental effects in offspring. Given that valproate is often the antiseizure drug of choice for genetic generalised epilepsies, this creates a dilemma for patients and clinicians. Decision making can be aided by comprehensive assessment and discussion of treatment options. Psychiatric comorbidities are common in adolescents and adults with genetic generalised epilepsies. These worsen the prognosis, both in terms of seizure control and quality of life. Attendant lifestyle issues can impact significantly on the individual and society. Frontal lobe dysfunction, which can present in patients with juvenile myoclonic epilepsy, can adversely affect the long-term outlook, regardless of the nature of seizure control. Ongoing management requires consideration of psychosocial and behavioural factors that can complicate diagnosis and treatment. An assured supportive attitude by the neurologist can be an important contributor to a positive outcome. The mechanisms underlying genetic generalised epilepsies, including genetic abnormalities, are unclear at present. As the pathophysiology is unravelled, this may lead to the development of novel therapies and improved outcomes for patients with these syndromes.
