Genetic causal attribution of epilepsy and its implications for felt stigma

Impact of a Genetic Diagnosis for a Child's Autism on Parental Perceptions

Genetic testing is recommended as part of an autism assessment, and most parents support genetic testing for their minor children. However, the impact on parents of receiving a monogenetic/ copy number variant diagnosis for autism in their child is not well understood. To explore this, we surveyed and interviewed parents of children in the SPARK study, a study of autism that includes genetic testing. Surveys were administered one month before and one and 12 months after parents received their child's genetic result. Interviews were conducted approximately one month after results disclosure. A genetic diagnosis (GD) for their child appeared to reduce parents' sense of self-blame and feelings of guilt, and this impact was relatively stable. The data also indicate a modest impact on parents' actions related to the condition, perceptions of themselves, and some aspects of life planning for their child, as measured by quantitative instruments at one month and 12 months after receipt of results. Other measures of parental identity and expectations for their child, in contrast, showed little change following receipt of genetic findings. Overall, parents who were told that no GD was identified showed minimal changes in their responses over time. These results suggest a discernable but relatively limited impact of genetic test results on parents of children with autism. These results should be reassuring to clinicians caring for children with autism and are consistent with studies in other areas of medicine that have suggested that genetic results tend to have fewer effects-negative or positive-than were anticipated.

Familial KCNQ2 mutation: a psychiatric perspective

KCNQ2 mutations are a common cause of early-onset epileptic syndromes. They are associated with heterogeneous developmental profiles, from mild to severe cognitive and social impairments that need better characterization. We report a case of an inherited KCNQ2 mutation due to a deletion c.402delC in a heterozygous state, in the exon 3 of the KCNQ2 gene. A 5-year-old boy presented a cluster of sudden-onset generalized tonic-clonic seizures at three months of age, after an unremarkable postnatal period. Multiplex ligation-dependent probe amplification identified a familial mutation after an investigation in the family revealed that this mutation was present on the father's side. The patient was diagnosed with autism and intellectual deficiency in a context of KCNQ2 -encephalopathy. We describe his clinical features in light of current literature. This report highlights the importance of appropriate genetic counseling and psychiatric assessment in planning the medical and social follow-up of a disorder with complex socio-behavioral features.

Knowledge and beliefs about epilepsy genetics among Hispanic and non-Hispanic patients

OBJECTIVE

Hispanics continue to face challenges when trying to access health care, including epilepsy care and genetic-related health care services. This study examined epilepsy genetic knowledge and beliefs in this historically underserved population.

METHODS

Questionnaires were completed by 641 adults with epilepsy without identified cause, of whom 122 self-identified as Hispanic or Latino and 519 as non-Hispanic. Participants were asked about their views on the contribution of genetics to the cause of their epilepsy ("genetic attribution"), optimism for advancements in epilepsy genetic research ("genetic optimism"), basic genetic knowledge, and epilepsy-specific genetic knowledge. Generalized linear models were used to compare the two groups in the means of quantitative measures and percents answered correctly for individual genetic knowledge items. Analyses were adjusted for age, sex, education, religion, family history of epilepsy, and time since last seizure.

RESULTS

Hispanics did not differ from non-Hispanics in genetic attribution, genetic optimism, or number of six basic genetic knowledge items answered correctly. The number of nine epilepsy-specific genetic knowledge items answered correctly was significantly lower for Hispanics than non-Hispanics (adjusted mean = 6.0 vs. 6.7, p < .001). After adjustment for education and other potential mediators, the proportion answered correctly was significantly lower for Hispanics than non-Hispanics for only two items related to family history and penetrance of epilepsy-related genes. Only 54% of Hispanics and 61% of non-Hispanics answered correctly that "If a person has epilepsy, his or her relatives have an increased chance of getting epilepsy."

SIGNIFICANCE

Despite large differences in sociodemographic variables including education, most attitudes and beliefs about genetics were similar in Hispanics and non-Hispanics. Epilepsy-specific genetic knowledge was lower among Hispanics than non-Hispanics, and this difference was mostly mediated by differences in demographic variables. Genetic counseling should address key concepts related to epilepsy genetics to ensure they are well understood by both Hispanic and non-Hispanic patients.

Low quality of life, increased number of anti-seizure drugs, and the lack of caregiver support are associated with internalized stigma in adult Mexican patients with epilepsy

BACKGROUND

People with epilepsy (PWE) have been subject to stigma throughout history, a factor that could compromise their performance in daily life. In Mexico, little is known about the factors that may be affecting internalized stigma.

OBJECTIVE

To evaluate the internalized stigma in adult PWE, its relationship with the quality of life, cognitive and depressive symptomatology, and clinical-demographic characteristics.

MATERIAL AND METHODS

We conducted a cross-sectional study with a consecutive sampling approach in patients with epilepsy treated at the National Institute of Neurology and Neurosurgery Manuel Velasco Suárez (NINNMVS). Sociodemographic and clinical data, depressive symptomatology (Beck's depression inventory, DBI), cognition (MoCA test), quality of life (QOLIE-31 scale), and internalized stigma (King's internalized stigma scale, ISS) were evaluated. Correlations were made between the continuous variables and the ISS to select those with statistical significance and include them in a multiple linear regression model, along with the dummy variables, to explain internalized stigma.

RESULTS

Of 128 patients, 74 (58%) were women; 38% of the patients had more than 20 years of epilepsy evolution. In addition, 39% presented depressive symptoms, and around 60% manifested a possible cognitive impairment. The variables that showed statistical significance concerning the ISS were selected along with dummy variables for multiple linear regression analysis. The resultant model considers the QOLIE-31 total score (β = -0.489), the number of anti-seizure drugs (ASD, β = 0.253), and those patients without caregiver support (β = -0.166) with an adjusted R² value of 0.316.

CONCLUSIONS

A diminishing quality of life, an increased number of ASD, and patients without caregiver support influence a slight to moderate variation of internalized stigma in Mexican PWE. Therefore, it is necessary to continue studying other possible factors that influence internalized stigma to generate effective strategies to reduce its negative effects on PWE.

Stigma and its association with health-related quality of life in adults with epilepsy

OBJECTIVE

To explore the presence of felt and enacted stigma in people with epilepsy (PWE), members of a self-governing epilepsy organization and to evaluate the influence of both types of stigma on health-related quality of life (HRQoL) in PWE.

METHODS

Participants were 55 PWE (age range: 18-53 years), members of a non-governmental organization (further "NGO"). The sociodemographic and epilepsy-related variables were collected through structured interviews designed for the purpose of the study. Felt stigma was assessed with the Epilepsy Stigma Scale (ESS) and enacted stigma with the Questionnaire for episodes of discrimination against PWE. Quality of Life in Epilepsy Inventory (QOLIE-31) (Serbian version) was used for the evaluation of HRQoL.

RESULTS

The mean ESS score was 33.93 ± 14.50. Felt stigma was significantly associated with the male gender and the number of antiepileptic drugs (AEDs). Participants' mean score on the Questionnaire for episodes of discrimination was 2.80 ± 2.78. Enacted stigma was significantly correlated with male gender and number of AEDs, as well as with older age/longer duration of the disorder. Felt stigma scores were positively correlated with enacted stigma scores (p < 0.001), but only felt stigma scores were negatively related to QOLIE-31 overall score (p = 0.01). The combination of AEDs, seizure frequency, and felt stigma best explained the HRQoL in PWE (p < 0.001).

CONCLUSION

Felt and enacted stigma are moderately related, but only felt stigma appears to be a significant predictor of the deteriorating HRQoL in this sample. Interventions targeting felt stigma should be considered a part of comprehensive epilepsy care as well as educating the wider community about epilepsy.

Development and validation of the Japanese version of the Epilepsy Stigma Scale in adults with epilepsy

BACKGROUND

Self-stigma is considered to have immensely negative influences on the living and psychological states in patients with epilepsy. Understanding the stigma experienced by patients with epilepsy is essential considering its negative impact on their treatment and quality of life (QOL). However, few sufficiently validated self-report instruments are available to evaluate self-stigma in patients with epilepsy. The Epilepsy Stigma Scale (ESS) is one of the most commonly used self-reported questionnaires available to evaluate self-stigma in patients with epilepsy. The present study translated the ESS into Japanese to validate the Japanese version of the ESS (ESS-J) in Japanese adults with epilepsy.

METHODS

The study included 338 patients with epilepsy (166 men, aged 18-75 years) who underwent comprehensive assessment including long-term video-electroencephalography monitoring, neuroimaging studies, and neuropsychological and psychosocial assessments in the Tohoku University Hospital Epilepsy Monitoring Unit. This study consisted of two phases: (1) translation of the ESS into Japanese using the back-translation technique; and (2) statistical analysis of the ESS-J to evaluate the factor structure, reliability, and validity.

RESULTS

The 2-factor model achieved acceptable fit to the data: χ² = 161.27, df = 34, p < 0.01, comparative fit index = 0.929, root mean square error of approximation = 0.105, standardized root mean squared residual = 0.047, Akaike's information criterion = 203.27 and, Bayesian information criterion = 283.56. These two subscales were named enacted stigma and felt stigma based on the theoretical model of self-stigma. We found the ESS-J to have acceptable internal consistency as follows: enacted (7 items; α = 0.88) and felt stigma subscale (3 items; α = 0.82). The concurrent validity was confirmed by adequate correlation with other related instruments. Both enacted and felt stigma had positive and moderate correlations with depression as measured by the Neurological Disorders Depression Inventory for Epilepsy (r = 0.44, p < 0.01; r = 0.41, p < 0.01, respectively) and with anxiety as measured by the Generalized Anxiety Disorder -7 (r = 0.48, p < 0.01; r = 0.38, p < 0.01, respectively).

CONCLUSION

The ESS-J demonstrated acceptable validity and reliability. The present study provided preliminary evidence about the psychometric properties of the ESS-J, indicating the reliable factorial structure, adequate internal consistency, and satisfactory construct and concurrent validity. Measurement of the two types of self-stigma may offer a useful tool for clinical interpretation of patients' psychological state throughout epilepsy care, and as one of the patient-reported outcomes in QOL research.

Systematic review of frequency of felt and enacted stigma in epilepsy and determining factors and attitudes toward persons living with epilepsy-Report from the International League Against Epilepsy Task Force on Stigma in Epilepsy

OBJECTIVE

To review the evidence of felt and enacted stigma and attitudes toward persons living with epilepsy, and their determining factors.

METHODS

Thirteen databases were searched (1985-2019). Abstracts were reviewed in duplicate and data were independently extracted using a standardized form. Studies were characterized using descriptive analysis by whether they addressed "felt" or "enacted" stigma and "attitudes" toward persons living with epilepsy.

RESULTS

Of 4234 abstracts, 132 met eligibility criteria and addressed either felt or enacted stigma and 210 attitudes toward epilepsy. Stigma frequency ranged broadly between regions. Factors associated with enacted stigma included low level of knowledge about epilepsy, lower educational level, lower socioeconomic status, rural areas living, and religious grouping. Negative stereotypes were often internalized by persons with epilepsy, who saw themselves as having an "undesirable difference" and so anticipated being treated differently. Felt stigma was associated with increased risk of psychological difficulties and impaired quality of life. Felt stigma was linked to higher seizure frequency, recency of seizures, younger age at epilepsy onset or longer duration, lower educational level, poorer knowledge about epilepsy, and younger age. An important finding was the potential contribution of epilepsy terminology to the production of stigma. Negative attitudes toward those with epilepsy were described in 100% of included studies, and originated in any population group (students, teachers, healthcare professionals, general public, and those living with epilepsy). Better attitudes were generally noted in those of younger age or higher educational status.

SIGNIFICANCE

Whatever the specific beliefs about epilepsy, implications for felt and enacted stigma show considerable commonality worldwide. Although some studies show improvement in attitudes toward those living with epilepsy over time, much work remains to be done to improve attitudes and understand the true occurrence of discrimination against persons with epilepsy.

Validity and reliability of the Chinese version of the epilepsy stigma scale

OBJECTIVE

This study was conducted to test the validity and reliability of the Chinese version of the epilepsy stigma scale (ESS), which aims to better understand the stigma of patients with epilepsy (PWEs), lays the foundation for future investigation and explores appropriate strategies to mitigate PWEs' stigma in Chinese culture.

METHODS

The scale was translated following standard procedures. For psychometric validation, the Chinese version of the ESS was administered to 214 PWEs above the age of 16 who were diagnosed with epilepsy by two trained epileptologists and were taking anti-seizure drugs for at least a month. All of the patients were recruited from Xiangya Hospital of Central South University of China from August 2021 to September 2021.

RESULTS

The Cronbach's alpha coefficient was 0.893 for the entire scale, 0.903 for felt stigma, and 0.688 for enacted stigma. Exploratory and confirmatory factor analyses were conducted and showed that the scale was grouped under two dimensions, and the results of confirmatory factor analysis support the structure.

CONCLUSION

The Chinese version of the ESS is a valid and reliable tool to assess epilepsy-related stigma in Chinese culture.

Reproductive decision-making in families containing multiple individuals with epilepsy

OBJECTIVE

This study evaluated factors influencing reproductive decision-making in families containing multiple individuals with epilepsy.

METHODS

One hundred forty-nine adults with epilepsy and 149 adult biological relatives without epilepsy from families containing multiple affected individuals completed a self-administered questionnaire. Participants answered questions regarding their belief in a genetic cause of epilepsy (genetic attribution) and estimated risk of epilepsy in offspring of an affected person. Participants rated factors for their influence on their reproductive plans, with responses ranging from "much more likely" to "much less likely" to want to have a child. Those with epilepsy were asked, "Do you think you would have wanted more (or any) children if you had not had epilepsy?"

RESULTS

Participants with epilepsy had fewer offspring than their unaffected relatives (mean = 1.2 vs. 1.9, p = .002), and this difference persisted among persons who had been married. Estimates of risk of epilepsy in offspring of an affected parent were higher among participants with epilepsy than among relatives without epilepsy (mean = 27.2 vs. 19.6, p = .002). Nineteen percent of participants with epilepsy responded that they would have wanted more children if they had not had epilepsy. Twenty-five percent of participants with epilepsy responded that "the chance of having a child with epilepsy" or "having epilepsy in your family" made them less likely to want to have a child. Having these genetic concerns was significantly associated with greater genetic attribution and estimated risk of epilepsy in offspring of an affected parent.

SIGNIFICANCE

People with epilepsy have fewer children than their biological relatives without epilepsy. Beliefs about genetic causes of epilepsy contribute to concerns and decisions to limit childbearing. These beliefs should be addressed in genetic counseling to ensure that true risks to offspring and reproductive options are well understood.

Risk and protective factors related to stigma among people with epilepsy: An integrative review

INTRODUCTION

Stigma is a critical issue among people with epilepsy (PWE). There is a need to undertake an integrative review of the factors associated with stigma, as it is experienced subjectively, and cannot be fully understood through quantitative research alone. The aims of this study were to explore the factors influencing epilepsy-associated stigma and to extend our understanding of stigma using an integrative review approach.

METHODS

Three databases (i.e., CINAHL, PubMed, and PsycINFO) were searched for articles published from January 2010 through December 2018 on stigma among PWE. Selected articles were assessed for quality using the mixed-method appraisal tool. The matrix method was used for data extraction and analysis. Overall, the process of the review was guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist.

RESULTS

Overall, 26 studies were included in this review: four qualitative studies, twenty-one quantitative studies, and one mixed-method study. Several factors associated with stigma were found, divided into four categories across two main aspects: individual (i.e., disease and social characteristics) and community (i.e., overall impression/beliefs regarding epilepsy and social networks) based on the Framework Integrating Normative Influences on Stigma.

CONCLUSIONS

The impression of and beliefs about epilepsy among the general population as well as among PWE were the primary factors affecting stigma. Thus, there is a need for the provision of accurate information about epilepsy to both these groups. Additional studies on epilepsy-associated stigma employing various methodological approaches are required.

Genetic attribution and perceived impact of epilepsy in multiplex epilepsy families

OBJECTIVE

Studies have found that affected individuals who believe the cause of their disorder is genetic may react in various ways, including optimism for improved treatments and pessimism due to perceived permanence of the condition. This study assessed the psychosocial impact of genetic attribution among people with epilepsy.

METHODS

Study participants were 165 persons with epilepsy from multiplex epilepsy families who completed a self-administered survey. Psychosocial impact of epilepsy was assessed with the Impact of Epilepsy Scale, containing items about relationships, employment, overall health, self-esteem, and standard of living. Genetic attribution was assessed using a scale derived from three items asking about the role of genetics in causing epilepsy in the family, the chance of having an epilepsy-related mutation, and the influence of genetics in causing the participant's epilepsy. We estimated prevalence ratios (PRs) for impact of epilepsy above the median using Poisson regression with robust standard errors, adjusting for number of lifetime seizures and time since last seizure.

RESULTS

Participants' age averaged 51 years; 87% were non-Hispanic white, 63% were women, and 54% were college graduates. The genetic attribution scale was significantly associated with having a high impact of epilepsy (adjusted PR = 1.4, 95% confidence interval = 1.07-1.91, P = .02). One of the three genetic attribution questions was also significantly associated with a high impact of epilepsy (belief that genetics had a big role in causing epilepsy in the family, adjusted PR = 1.8).

SIGNIFICANCE

These findings reflect an association between the psychosocial impact of epilepsy and the belief that epilepsy has a genetic cause, among people with epilepsy in families containing multiple affected individuals. This association could arise either because belief in a genetic cause leads to increased psychosocial impacts, or because a greater psychosocial impact of epilepsy leads some to believe their epilepsy is genetic.

Stigma, emotional aspects, and psychological symptoms in individuals with epilepsy

The relationship between stigma and psychological aspects in adults with epilepsy is poorly studied. The Stigma Scale of Epilepsy (SSE) was related to the Factorial Neuroticism Scale (FNS), Symptoms Assessment Scale-40 (SAS-40), and clinical aspects of 71 individuals with epilepsy, at a significance level of p < 0.05. Clinical and sociodemographic aspects are associated with the presence of psychological symptoms and emotional maladjustment. The occurrence of psychological symptoms in the SAS-40 was associated with uncontrolled seizures, longer illness duration, and perception of greater stigma. There was a relationship between perceived stigma, age, and epilepsy duration. In the linear regression for determining the factors that potentially affected perception of stigma, the symptom dimensions 'somatization' in the SAS-40 (p < 0.001) and the 'psychosocial maladjustment' in the FNS (p = 0.012) were included, and the clinical aspects were excluded. Psychological symptoms were associated with uncontrolled seizures and perceived stigma. Perception of stigma was associated with somatization and psychosocial maladjustment.

Sociocultural aspects and different types of stigmatization in epilepsy

This literature review deals with knowledge and beliefs about epilepsy and with the attitude of patients, relatives, and society as a whole towards epilepsy. It discusses the stigma that is associated with the  disease and has a strong impact on patients with epilepsy and their  families. The problems of stigma or related concepts in different countries are analyzed.

Correlates of stigma in adults with epilepsy: A systematic review of quantitative studies

OBJECTIVES

The aim of this review was to identify quantitative correlates, predictors, and outcomes of stigma in adults with epilepsy living in Western countries.

METHODS

To identify relevant literature, four academic databases (PsycINFO, CINAHL, PubMed, and Scopus) were systematically searched using key terms related to stigma and epilepsy.

RESULTS

Thirty-three research papers reporting findings from 25 quantitative studies of correlates of stigma in epilepsy were identified. The findings suggest that stigma can be predicted by demographic, illness-related, and psychosocial factors, although associations were found to be highly culturally specific. Outcomes of stigma in people with epilepsy were replicated more consistently across cultures, and its impact was significant. Detrimental effects included both worse physical health, including less effective management of the condition, and reduced psychological well-being, including difficulties such as depression and anxiety.

IMPLICATIONS

Educational initiatives and therapeutic interventions that aim to address stigma in people with epilepsy are recommended; however, these need to be culturally informed to ensure that they are valid and effective.

Mood disorders in familial epilepsy: A test of shared etiology

OBJECTIVE

Mood disorders are the most common comorbid conditions in epilepsy, but the cause remains unclear. One possible explanation is a shared genetic susceptibility to epilepsy and mood disorders. We tested this hypothesis by evaluating lifetime prevalence of mood disorders in relatives with and without epilepsy in families containing multiple individuals with epilepsy, and comparing the findings with rates from a general population sample.

METHODS

The Composite International Diagnostic Interview was administered to 192 individuals from 60 families, including 110 participants with epilepsy of unknown cause (50 focal epilepsy [FE], 42 generalized epilepsy [GE], 6 FE and GE, 12 unclassifiable) and 82 relatives without epilepsy (RWOE). Odds ratios (ORs) for lifetime prevalence of mood disorders in participants with versus without epilepsy were computed through logistic regression, using generalized estimation equations to account for familial clustering. Standardized prevalence ratios (SPRs) were used to compare prevalence in family members with general population rates.

RESULTS

Compared with RWOE, ORs for mood disorders were significantly increased in participants with FE (OR = 2.4, 95% confidence interval [CI] = 1.1-5.2) but not in those with GE (OR = 1.0, 95% CI = 0.4-2.2). In addition, prevalence of mood disorders was increased in individuals with epilepsy who had ≥1 relative with FE. Compared with general population rates, mood disorders were significantly increased in individuals with FE but not in those with GE. Rates were also increased in RWOE, but not significantly so (SPR = 1.4, P = .14).

SIGNIFICANCE

These findings are consistent with the hypothesis of shared genetic susceptibility to epilepsy and mood disorders, but suggest (1) the effect may be restricted to FE, and (2) the shared genetic effect on risk of mood disorders and epilepsy may be restricted to individuals with epilepsy, that is, to those in whom the genetic risk for epilepsy is "penetrant."

Depression and genetic causal attribution of epilepsy in multiplex epilepsy families

OBJECTIVES

Rapid advances in genetic research and increased use of genetic testing have increased the emphasis on genetic causes of epilepsy in patient encounters. Research in other disorders suggests that genetic causal attributions can influence patients' psychological responses and coping strategies, but little is known about how epilepsy patients and their relatives will respond to genetic attributions of epilepsy. We investigated the possibility that among members of families containing multiple individuals with epilepsy, depression, the most frequent psychiatric comorbidity in the epilepsies, might be related to the perception that epilepsy has a genetic cause.

METHODS

A self-administered survey was completed by 417 individuals in 104 families averaging 4 individuals with epilepsy per family. Current depression was measured with the Patient Health Questionnaire. Genetic causal attribution was assessed by three questions addressing the following: perceived likelihood of having an epilepsy-related mutation, perceived role of genetics in causing epilepsy in the family, and (in individuals with epilepsy) perceived influence of genetics in causing the individual's epilepsy. Relatives without epilepsy were asked about their perceived chance of developing epilepsy in the future, compared with the average person.

RESULTS

Prevalence of current depression was 14.8% in 182 individuals with epilepsy, 6.5% in 184 biologic relatives without epilepsy, and 3.9% in 51 individuals married into the families. Among individuals with epilepsy, depression was unrelated to genetic attribution. Among biologic relatives without epilepsy, however, prevalence of depression increased with increasing perceived chance of having an epilepsy-related mutation (p = 0.02). This association was not mediated by perceived future epilepsy risk among relatives without epilepsy.

SIGNIFICANCE

Depression is associated with perceived likelihood of carrying an epilepsy-related mutation among individuals without epilepsy in families containing multiple affected individuals. This association should be considered when addressing mental health issues in such families.

Raising Genomic Citizens: Adolescents and the Return of Secondary Genomic Findings

Whole genome and exome sequencing (WGS/WES) techniques raise hope for a new scale of diagnosis, prevention, and prediction of genetic conditions, and improved care for children. For these hopes to materialize, extensive genomic research with children will be needed. However, the use of WGS/WES in pediatric research settings raises considerable challenges for families, researchers, and policy development. In particular, the possibility that these techniques will generate genetic findings unrelated to the primary goal of sequencing has stirred intense debate about whether, which, how, and when these secondary or incidental findings (SFs) should be returned to parents and minors. The debate is even more pronounced when the subjects are adolescents, for whom decisions about return of SFs may have particular implications. In this paper, we consider the rise of "genomic citizenship" and the main challenges that arise for these stakeholders: adolescents' involvement in decisions relating to return of genomic SFs, the types of SFs that should be offered, privacy protections, and communication between researchers and adolescents about SFs. We argue that adolescents' involvement in genomic SF-related decisions acknowledges their status as valuable stakeholders without detracting from broader familial interests, and promotes more informed genomic citizens.
