Depression and quality of life in patients with epilepsy in Northwest Greece

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.

Association between breakfast consumption, breakfast quality, mental health and quality of life in Turkish adolescents: A high school-based cross-sectional study

This study aimed to determine the frequency of breakfast consumption and breakfast quality among adolescents and to evaluate the relationships between breakfast consumption, breakfast quality, mental health, and health-related quality of life. This cross-sectional study included 449 students from 17 high schools between December 2022 and May 2023. A face-to-face questionnaire measuring the frequency of breakfast consumption, Mediterranean diet quality index (KIDMED), health-related quality of life (KIDSCREEN), and depression, anxiety and stress scales (DASS-21) was performed. Of the students, 54.1% skipped breakfast 2 or more times a week and 75.9% had poor breakfast quality. There were significant differences in breakfast quality classification according to the frequency of breakfast consumption (p = 0.003). Breakfast consumption ≤1 time/week or 2-5 times/week was associated with depression, anxiety and low adherence to the Mediterranean diet. No relationship was observed between breakfast quality and stress, depression or anxiety (p = 0.620, p = 0.586, p = 0.539, respectively) or between breakfast quality and the KIDSCREEN-27 subscales (p > 0.05). However, those eating poor-quality breakfasts had better results in physical wellbeing (p = 0.022), psychological wellbeing (p = 0.024), autonomy and parent relations (p = 0.017) than breakfast-skippers and also scored lower for depression, stress and anxiety (all p < 0.001). In conclusion, the frequency of breakfast consumption had a stronger association with reduced symptoms of stress, depression and anxiety, as well as improvements in all dimensions of health-related quality of life, compared to the quality of breakfast consumed. Given the association of breakfast consumption with mental health outcomes in adolescents, our findings are of great importance, especially to parents, clinicians and nutritional educators.

Evaluation of quality of life's prognostic factors in people with functional seizures

AIMS

Functional non-epileptic seizures significantly impact the quality of life of patients. We aimed to identify prognostic factors associated with the quality of life in individuals with functional non-epileptic seizures.

SUBJECTS AND METHODS

Adult patients diagnosed with definite or documented functional seizures based on LaFrance's criteria (n=72) were enrolled at the time of diagnosis. Quality of life was assessed using the Quality of Life in Epilepsy Inventory-31 (QOLIE-31) at diagnosis and at a six-month follow-up. Demographic and medical information was collected, and psychiatric comorbidities were evaluated using validated scales.

RESULTS

Comparisons between diagnosis and follow-up did not reveal any factors associated with improvement in quality of life at six months after diagnosis. However, multivariable analysis, adjusted for age, sex, diagnosis delay, and frequency of functional seizures showed a significant cross-sectional relationship with a QOLIE-31 score decrease of 0.66 [95% CI -0.93;-0.39], -0.32 [-0.61; -0.03], and -0.22 [-0.42; -0.02] for an increase of 1 point of BDI-2 score, BAI score, and CTQ score respectively.

CONCLUSION

Psychiatric comorbidities, particularly depression and anxiety, are associated with worse quality of life in patients with functional seizures. This underscores the crucial importance of multidisciplinary care involving both neurological and psychiatric expertise when managing individuals with functional seizures.

Influence of sleep disturbance, depression, anxiety, and stress on quality of life in people with epilepsy

OBJECTIVES

We assessed the quality of life, sleep, depression, anxiety, and stress in people with pharmacoresistant epilepsy (PRE) and newly diagnosed epilepsy (NDE). We also assessed the influence of sleep, depression, anxiety, and stress on the quality of life (QOL) and the complex association between these factors.

METHODS

We recruited 80 PRE and 70 NDE people attending the epilepsy clinic. We assessed QOL, sleep quality, daytime sleepiness, and mood using the quality of life in epilepsy-31 inventory (QOLIE-31), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), and depression anxiety stress scale (DASS-21). We compared the results between the two groups of epilepsy populations. We performed univariate and multivariate linear regression to determine the factors affecting the QOLIE-31 total score. We applied Spearman's rank correlation to find the interrelationship between variables influencing QOL.

RESULTS

We found significantly lower QOLIE-31 total scores (p = .001) in PRE compared to NDE. The PSQI and ESS did not differ significantly between the PRE and NDE groups. Anxiety (p = .002) and stress (p = .003) scores were significantly higher in PRE than in NDE. QOLIE-31 total scores showed a negative correlation with PSQI as well as symptoms of depression, anxiety, and stress scores in both groups. Multiple linear regression analysis revealed depression as a major factor influencing the QOLIE-31 total score in PRE (p = .001) and NDE (p = .003). We found significant complex associations between PSQI, depression, anxiety, stress, and QOLIE total scores in both groups.

SIGNIFICANCE

The QOL is poorer for people with PRE than for those with NDE. Depression is a major determinant of QOL in PWE. These factors need to be considered to improve the QOL in epilepsy.

Family support in adults with epilepsy

BACKGROUND

 The perception of family support in chronic disease can be relevant.

OBJECTIVE

 To assess the perception of family support in adult patients with epilepsy (PWEs) and relate it to quality of life (QoL) and clinical aspects.

METHODS

 Data from the Perceived Family Support Inventory (IPFS) of 130 PWEs were related to the clinical variables, QOLIE-31 scores, and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) with statistical tests, with p < 0.05.

RESULTS

 The mean age was 49.9 ± 17.2 years, and the duration of epilepsy was 20.8 ± 15.4 years. The presence of depression (scores ≥ 15) was associated with lower family support. Being married and non-occurrence of depression were the variables associated with a higher IPFS score (R = 0.2112), in the multiple linear regression.

CONCLUSION

 The perception of greater family support was associated with demographic aspects, the absence of depression, and better QoL. Family relationships may play an essential role in health adjustment behaviors and QoL in epilepsy.

The impact of epilepsy and antiseizure medications on sleep: Findings from a large European survey in adults with epilepsy and matched controls

OBJECTIVE

To assess the impact of epilepsy and antiseizure medications (ASMs) on sleep quality in people with epilepsy (PWE).

METHODS

An online survey was conducted in France, Germany, Italy, Spain and the UK among PWE taking >1 ASM and matched controls. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). Associations between sleep quality (global PSQI) and overall quality of life (QoL; assessed using the 12-Item Short Form Survey [SF-12]) and sleep quality and depressive symptoms (assessed using the Neurological Disorders Depression Inventory for Epilepsy [NDDI-E]) were also evaluated.

RESULTS

Overall, 500 PWE and 500 matched controls were included. PWE had significantly greater mean global PSQI scores than controls (9.32 vs 7.56; p < 0.0001), with 80% reporting a score >5 versus 66% of controls (p < 0.001). PWE experienced significantly more problems with most PSQI components than controls. Mean global PSQI scores in PWE receiving 2 versus ≥3 ASMs were 9.03 and 10.18, respectively (p < 0.004); global PSQI scores >5 were reported in 76% versus 90%, respectively (p = 0.001). Regimens containing lamotrigine or phenobarbital were associated with poorer sleep quality than those without these ASMs. In PWE, negative correlations were identified between global PSQI scores and both the SF-12 physical and mental components (Pearson's correlation coefficient [PCC], -0.61 and -0.40, respectively); NDDI-E and global PSQI scores were positively correlated (PCC, 0.6).

CONCLUSIONS

PWE experience significantly worse sleep quality than people without epilepsy, with some ASMs contributing to poorer sleep. QoL and physical and mental health were all affected by sleep quality in PWE.

The impact of epilepsy on quality of life: Findings from a European survey

INTRODUCTION

Epilepsy is a serious neurological disorder affecting the quality of life (QoL) of people with this condition. A survey was conducted in five European countries (France, Germany, Italy, Spain, and the UK) to understand the impact and burden of epilepsy and its treatment on the lives of people with epilepsy (PWE).

METHODS

Five hundred PWE (taking >1 antiseizure medication [ASM]) and 500 matched controls completed a 30-minute online questionnaire. The 12-Item Short Form Survey (SF-12) was used to measure QoL and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) was used to screen for major depressive disorder (MDD) symptoms.

RESULTS

Comorbidities such as migraine, high cholesterol, osteoporosis, and Type 1 diabetes were reported more commonly in PWE, while anxiety disorders, high blood pressure, skin disorders, and mood disorders were more common in controls. However, compared to controls, a significantly higher percentage of PWE had an NDDI-E score of 15-24 (54% vs 35%; p < 0.0001), indicative of MDD symptoms. Significantly more PWE than controls were part-time employed (15% vs 11%; p = 0.03). People with epilepsy had a significantly lower total SF-12 score than controls across the physical and the mental components; compared to controls, a significantly higher proportion of PWE defined their general health as 'poor' or 'fair' and felt limited in carrying out daily and work activities. Among PWE, those taking ≥3 ASMs were more likely to experience difficulties in carrying out these activities than those on two ASMs. Ability to drive, mood, and level of self-esteem were reported as concerns for PWE.

CONCLUSION

Epilepsy has a major impact on the physical and mental health of PWE, interfering with their daily and work activities and overall QoL, and its treatment might also contribute to a lower QoL. The impact of epilepsy on mood and mental health might be under-recognized.

Association of depression and epilepsy in Rwanda: A prospective longitudinal study

INTRODUCTION

Depression is the most common psychiatric comorbidity for persons living with epilepsy. In Rwanda, the prevalence of epilepsy and depression are high, with 4,9% and 13.0% respectively. This prospective interventional study aimed to determine the prevalence and incidence of depression and the outcome of persons living with epilepsy (PwE) with depression attending the outpatient neurology department of a tertiary center.

METHODS

Persons living with epilepsy enrolled between February and June 2018 in a screening cohort with a 12-month follow-up. At every 3-month study visit, PwE were screened for depression using the Patient Health Questionnaire (PHQ-9) questionnaire. Any positively screened subject was administered the Hamilton Depression Rating Scale (HDRS) to confirm the diagnosis and severity of depression. Subjects with moderate to severe depression (MSD), were started on treatment and were followed for another year. We describe the prevalence and incidence of depression, baseline characteristics, epilepsy and depression outcomes, and changes in PGI-C.

RESULTS

Of 572 PwE enrolled, 46 were diagnosed with MSD in a twelve-month period, resulting in an incidence of MSD of 32.7/1000 patient-years. The prevalence of any depression and MSD was 14.2% and 4.7%, respectively. Longer epilepsy duration and seizure status at baseline were associated with MSD. Significant improvements in PGI-C and seizure frequency were observed after treatment optimization.

CONCLUSION

The use of PHQ-9 and HDRS proved successful in identifying depression in PwE. Combined treatment of epilepsy and depression resulted in improved outcomes, warranting the implementation of depression screening every six months in daily neurology practice.

Quality of Life in Adult Patients With Epilepsy in Lebanon: A Cross-Sectional Study

BACKGROUND

Epilepsy is a chronic and heterogeneous neurological disorder that impairs the quality of life (QOL) of sufferers and affects their mental health in many aspects. Few studies have been conducted in the Middle East, especially in Lebanon, on the QOL of patients with epilepsy. The aim of our study is to assess the burden of epilepsy on the life of adult patients in Lebanon and measure the impact of sociodemographic and clinical factors on the QOL.

MATERIALS AND METHODS

A total of 47 patients from several neurology clinics were included in our study and asked to fill out a questionnaire including the sociodemographic variables and epilepsy-related factors. We used the Quality of Life in Epilepsy Scale-31 (QOLIE-31), which is a 31-question form covering seven attributes of the QOL; overall QOL, emotional wellbeing, social functioning, cognition, energy, seizure worry and medication effects, to assess the QOL of adult patients with epilepsy. Analysis was conducted using SPSS program version 23.

RESULTS

The mean age of our sample was 37.54 years, 53.2% of which were males. The majority were unemployed, educated, and belonging to the medium socioeconomic level. The highest subscale score was for the social functioning subscale with a mean of 74.49±25.89 and the lowest subscale score was for seizure worry with a mean of 55.81±27.14. Employment status, nationality, and socioeconomic level were shown to be associated with the QOL scores. There were no correlations between the clinical factors and the QOL scores.

CONCLUSION

 Sociodemographic factors, namely Lebanese nationality, employment status, and socioeconomic level, were associated with better QOL, reflected by the significant associations between the following parameters and the QOL scores (p-value<0.05), highlighting the positive influence of social support on the outcome of the disease. However, epilepsy-related clinical features did not show any correlation with the QOL and its subscales.

The WHOQOL-BREF instrument: Psychometric evaluation of the Greek version in patients with advanced cancer and pain and associations with psychological distress

OBJECTIVES

Assessment of the psychometric characteristics of the Greek version of the brief World Health Organization Quality of Life Instrument (WHOQOL-BREF) in patients with advanced cancer and pain, and exploration of the association between psychological distress and quality of life (QoL).

METHOD

The sample consisted of 145 patients with advanced cancer and pain who completed the WHOQOL-BREF, the Symptom Checklist-90 (SCL-90), and the Pain Visual Analogue Scale (VAS). In analysis, the following methods were used: Cronbach's alpha, Item Response Theory (IRT), polychoric, Pearson and polyserial correlation, t-test, and Linear regression.

RESULTS

The internal consistency was high for all domains of the WHOQOL-BREF (Cronbach's α ≥ 0.731). Similarly, with the exception of three items, the WHOQOL-BREF items has large discrimination parameters suggesting that they have a high ability in differentiating subjects. On SCL-90, the three dimensions with the highest scores were Depression, Somatization, and Anxiety. The overall score for psychological distress, the Global Severity Index (GSI), showed significant negative association with all the WHOQOL-BREF factor scores (Physical Health: B = -1.488, p < 0.001, Psychological Health: B = -1.688, p < 0.001, Social Relationships: B = -0.910, p < 0.001, Environment: B = -1.064, p < 0.001). Male gender was associated with lower scores for Social Relationships (B = -0.358, p = 0.007) and Environment (B = -0.293, p = 0.026).

SIGNIFICANCE OF RESULTS

The Greek version of the WHOQOL-BREF showed good psychometric properties in patients with advanced cancer and can be used as a reliable instrument in clinical practice. The level of psychological distress can be considered a determinant of QoL in patients with advanced cancer and pain, independently of pain intensity or other clinical characteristics. In cancer, the disease process can activate multiple physiological and psychological mechanisms that lead to a wide range of symptoms of psychological distress. To improve their QoL, psychological intervention focused on the identification and alleviation of psychological distress in patients with advanced cancer, and help in finding meaning in their experience, should be provided.

Effects of insomnia and levels of depression and anxiety symptoms on quality of life in people with epilepsy

OBJECTIVES

The association between insomnia and quality of life (QOL) in epilepsy is poorly understood and may involve interactive variables. We aimed to investigate whether and how insomnia, levels of depression and anxiety symptoms interact to influence QOL in people with epilepsy (PWE).

METHODS

A consecutive cohort of 179 PWE was enrolled. We collected data on insomnia, levels of depression and anxiety symptoms, and QOL. The Insomnia Severity Index (ISI), Depression Inventory for Epilepsy (NDDI-E), Generalized Anxiety Disorder-7 (GAD-7), and QOL in Epilepsy Inventory (QOLIE-31) were used. The direct, indirect, and total effects of insomnia on QOL were estimated based on a moderated mediation model.

RESULTS

Depression symptom levels mediated the association between insomnia and QOL (B = 0.09 SE = 0.03, p = 0.01). Depression symptom levels accounted for 34.7% of the total effect of insomnia on QOL. The mediating effect of depression symptom levels was positively moderated by anxiety symptom levels (B = 0.09, SE = 0.03, p = 0.01).

CONCLUSION

The effect of insomnia on QOL can be partially explained by the mediation of depression symptom levels. Additionally, improving anxiety symptoms may attenuate the indirect effect of insomnia on QOL through depression symptom levels.

Association between epilepsy and risk of depression: A meta-analysis

BACKGROUND

Recent studies provided inconsistent evidence for the association between epilepsy and risk of depression.

METHODS

We searched for articles published in the databases (Web of Science, Google Scholar and PubMed) and before December 2021. We used STATA 12.0 software to compute odds ratios (ORs)/relative risks (RRs) and their 95% confidence intervals (CIs).

RESULTS

The meta-analysis indicated that epilepsy was associated with an increased risk of depression with a random effects model (OR/RR = 2.05; 95% CI: 1.77-2.37, I² = 37.7%, p = 0.036). Subgroup studies indicated that epilepsy was associated with an increased risk of depression in both case-control and cohort studies (case-control studies: OR = 2.32; 95% CI: 1.91-2.82; cohort studies: RR = 1.71; 95% CI: 1.53-1.92). Subgroup studies indicated that epilepsy was associated with an increased risk of depression in Asian, African and Caucasian populations (Asian: OR/RR = 2.42; 95% CI: 1.48-3.95; African: OR/RR = 2.48; 95% CI: 1.88-3.28; Caucasian: OR/RR = 1.86; 95% CI: 1.60-2.15). Subgroup studies showed that epilepsy was associated with an increased risk of depression among adolescents and adults (adolescents: OR/RR = 2.54; 95% CI: 1.86-3.46; adults: OR/RR = 2.22; 95% CI: 1.79-2.75).

CONCLUSIONS

Epilepsy is at increased risk of depression comorbidity.

Patient complexity, depression, and quality of life in patients with epilepsy at an epilepsy center in Japan

Objective

The relationship between care complexity and quality of life among patients with epilepsy has not been assessed, especially in Japan. The aim of this study is to test the hypothesis that care complexity is associated with health‐related quality of life (HRQOL) and mood disturbance.

Method

This was an observational cross‐sectional study. The study included a consecutive series of 49 patients who newly visited an epilepsy center. Study participants were administered standardized quantitative measures of HRQOL, case complexity, and depression.

Results

Patient complexity predicted lower HRQL scores. Data on the social and psychological complexity domains predicted patient HRQOL findings more accurately than data from the biological domain of the case complexity scale. Seizure frequency was unrelated to HRQOL findings in this study. Additionally, depression scores were also associated with lower HRQOL.

Significance

A patient complexity assessment, including psychological and social domains, may be one of the key tools in epilepsy treatment settings. Further studies using larger random selection from patients with epilepsy are necessary to generalize the findings to patients in other epilepsy programs.

Chronic Pain and Its Association with Depressive Symptoms and Renal Function in Hypertensive Patients

Chronic pain is a common concern and is considered to be one of the major problems in patients with chronic physical disorders. We studied the effect of pain in patients with hypertension with or without chronic kidney disease (CKD) and the association between pain and symptoms of depression. The study involved 158 hypertensive individuals (59.5% male, mean age 55 years), of whom 47 (29.8%) had CKD (estimated glomerular filtration rate < 60 mL/min/1.73 m²). Pain was assessed with the pain/discomfort domain of the EuroQol-5 D, while depressive symptoms were assessed with the depression module of the Patient health questionnaire (PHQ-9). The prevalence of chronic pain in our sample was 44.3%. Women exhibited chronic pain more often compared to men (57.1% vs. 42.9%, p < 0.001). The presence of CKD was not significantly associated with a higher prevalence of chronic pain among hypertensive patients. Depressive symptoms were significantly associated with the presence of chronic pain. These findings were confirmed in the logistic regression analysis. Chronic pain is common in hypertensive individuals and the association with depression warrants further investigation and may have practical implications in managing these patients.

Prevalence of depression, risk factors, and quality of life in patients with epilepsy in a remote area of western Rajasthan

BACKGROUND

Depression is a common psychiatric disorder in patients with epilepsy. This study aimed to determine the prevalence and related risk factors for depression among people with epilepsy and their quality of life.

METHODS

Hospital-based cross-sectional study was carried out among 352 individuals with epilepsy from April 2020 to September 2020. Purposive sampling was used to recruit participants over a specified period. The Beck's Depression Inventory-II (BDI-II) was used to measure depression severity, the Perceived Stress Scale (PSS) to assess stress level, the Oslo 3 Social Support Scale (OSSS-3) to assess social support, and the WHOQOL-BREF scale to estimate quality of life (QoL). The statistical analysis was carried out using SPSS version 20. Logistic regression analysis was done to determine the risk factors for depression.

RESULTS

A total of 352 study participants were considered in the study. The prevalence of depression was found to be 41.19%. In the final multivariate analysis, the independent variables that influenced depression were socioeconomic status (OR 2.75, CI 1.21-5.41), frequency of seizures in the previous year (OR 2.17, CI 1.08-5.26), duration of illness (OR 3.49, CI 1.03-7.52), and poor social support (OR 6.37, CI 1.85-9.48) at p-value < 0.05. When compared to patients without depression, the average mean score (SD) in all four domains was lower in physical 39.01 (4.61), psychological 43.93 (8.13), social 52.89 (10.44), and environmental domains 47.14 (6.99) in patients with depression in BREF quality-of-life scale. There was a statistically significant difference in the physical, psychological, and social domains (p-value < 0.05).

CONCLUSION

In people with epilepsy, depression was quite common. Patients that were depressed had a lower QoL. Clinicians should pay special attention to people with epilepsy who lack social support, have low socioeconomic status, longer duration of illness, and have more seizure frequency. Qualified clinicians should do early depression-focused screenings for people with epilepsy.

Point prevalence of depression in persons with active epilepsy and impact of methodological moderators: A systematic review and meta-analysis

OBJECTIVES

The aim of this study was to determine the pooled prevalence of depression in persons with epilepsy and assess the methodological moderators affecting the prevalence estimates.

METHODS

Five electronic databases PubMed, The Cochrane Library, EMBASE, WHO Global Index Medicus, and Clinicaltrial.gov were searched for studies reporting prevalence of depression in PWE ≥ 18 years of age in any setting.

RESULTS

Out of 13,873 studies, after deduplication and screening, 56 studies with 10,527 PWE met the eligibility criteria. The overall pooled prevalence of depression in PWE was 32% (95%confidence interval [CI] 28-35%) and significant heterogeneity (Chi-square = 1171.53, p = 0.00; τ² = 0.02; I² = 94.36%). Prevalence has doubled in the recent years (16% in 2000-2005 vs. 35% in 2016-2020), was higher in Asia than in Europe (coefficient 0.899, 95%CI: 0.809-0.999; p = 0.049). Among assessment methods, prevalence was highest in HAM-D scale (54%, 95%CI: 27-82%) and lowest in MINI (22%, 95%CI: 19-26%). Sensitivity analysis also corroborated findings when MINI was excluded (35%, 95%CI: 31-38%).

CONCLUSIONS

A significant proportion of PWE have depression. Though there is substantial heterogeneity due to various methodological moderators, it is unlikely to affect the routine screening of PWE for depression. Use of a screening tool should be based on ease of administration, and cutoff selection should ensure identification of minimal depression as well.

Depression severity mediates the impact of perceived stigma on quality of life in patients with epilepsy

OBJECTIVE

To determine whether and the extent to which depression severity mediates the impact of perceived stigma on quality of life in patients with epilepsy (PWE).

METHODS

A consecutive cohort of 165 PWE was invited to participate in this study. Each participant completed the Kilifi Stigma Scale of Epilepsy (KSSE), Depression Inventory for Epilepsy (NDDI-E), and Quality of Life in Epilepsy Inventory (QOLIE-31). Mediation analysis was employed to assess whether depression severity mediates the relationship between perceived stigma and quality of life.

RESULTS

Perceived stigma was positively associated with depression severity and negatively associated with quality of life in PWE. The mediation analysis confirmed that perceived stigma had an indirect effect on the quality of life through the mediating variable of depression severity in PWE (B = -0.576, SE = 0.097, Bootstrap95% CI = -0.784 to -0.405). The indirect effects of perceived stigma on quality of life through depression severity accounted for 57.7% of the total effects of perceived stigma on quality of life.

CONCLUSION

This study provided evidence that depression severity mediates the impact that perceived stigma has on quality of life, indicating that assessment of and interventions targeting depression may be appropriate for PWE.

Perceived quality of life (QOLIE-31-P), depression (NDDI-E), anxiety (GAD-7), and insomnia in patients with epilepsy attended at a refractory epilepsy unit in real-life clinical practice

Objectives

This study aims to evaluate the relationship between psychiatric comorbidity (anxiety and depression), somnolence, and quality of life, using validated scales in patients with epilepsy in real-life clinical practice and clinical and demographic variables.

Methods

A cross-sectional observational study was conducted. Self-administered scales of anxiety disorders (GAD-7), depression (NDDI-E), somnolence (Epworth Sleepiness Scale (ESS)), and quality of life (QOLIE-31-P) in patients with epilepsy treated in the refractory epilepsy unit of a tertiary hospital were employed.

Results

Eighty-four patients, 44.3 ± 17.4 years, 48.2% women, epilepsy duration 21.5 ± 15.9 years, and number of antiepileptic drugs 1.9 ± 1.2 were included. Severe anxiety was present in 14.3%, depression in 20.2%, and somnolence in 14.3% of patients. QOLIE-31-P score was 62.0 ± 19.2. Depression and focal epilepsy (OR = 4.5[1.3, 20.7], p = 0.029), as well as anxiety and temporal lobe epilepsy (OR = 4.3 [1.0, 18.1], p = 0.044), were associated. Moreover, relationships between worse quality of life and higher scores from NDDI-E (β =  − 1.42, adjusted p = 0.006) and GAD-7 (β =  − 1.21, adjusted p = 0.006), especially in drug-resistant epilepsy (β =  − 8.08, adjusted p = 0.045) and female sex (β =  − 7.83, adjusted p = 0.034), were identified. Statistically significant negative associations were observed between problems to fall asleep and overall quality of life score (β =  − 11.64, adjusted p = 0.022), sleep disturbance and energy (β =  − 14.78, adjusted p = 0.027), and mood (β = 12.40, adjusted p = 0.027) scores.

Conclusions

The multidimensional evaluation revealed that higher levels of anxiety and depression are associated with worse quality of life in real clinical practice in patients with epilepsy, especially in females and drug-resistant epilepsy. In addition, sleep disturbances are associated with particular aspects of the quality of life. Further studies with longitudinal follow-up would be useful to adequately manage these comorbidities in patients with epilepsy.

Fatigue and cognitive functions in epilepsy: A review of the literature

Epilepsy is a common neurological disorder affecting people of all ages and inducing cognitive impairments. While research has advanced in terms of neuropsychological enquiries of the various epileptic syndromes, the understanding of more complex and ill-defined phenomena such as fatigue is still unclear for epilepsy. It is suggested that fatigue is not just physical, but there can also be a cognitive element to it. Although studies in other conditions have been able to identify a relationship between fatigue and particular cognitive components, similar evidence is sparse in patients with epilepsy. This review is an attempt to gather, analyze, integrate, and critically discuss available information on fatigue and its rapport with various aspects of epilepsy, particularly focusing on cognition. Future directions are discussed urging researchers to target cognitive components of fatigue.

Examining quality of life in an Australian cohort of people with epilepsy over six years - Understanding the role of stigma and mood

AIM

Research examining quality of life (QoL) among people living with epilepsy (PWE) consistently highlights the detrimental impact of stigma, anxiety, and depression, as well as the dynamic and changing nature of QoL over time. This paper represents the first panel study of the Australian Epilepsy Longitudinal Survey (AELS), examining factors that influence the QoL of PWE over a six-year interval, particularly focusing on experiences of stigma, depression, and anxiety.

METHODS

Ninety-two adults participated in both Wave 2 (T1; 2010) and Wave 4 (T2; 2016/17) of the AELS. Average age at T2 was 53.4 years [standard deviation (SD) = 15.3; range: 22-82; 55% female]. Over the study interval, there was a shift towards more younger participants moving out of high school and older participants moving into retirement. We explored the impact of (i) experiences of stigma, (ii) mood, and (iii) sociodemographic factors on QoL at both T1 and T2 via the use of correlation analyses. Hierarchical regression was used to determine the strongest predictors of QoL at T2.

RESULTS

Occurrence of recent seizures, stigma, anxiety, and depression measured at T1 were all significantly correlated with total QoL at both T1 and T2. Sociodemographic factors including years of education, and weekly income before tax were not significantly correlated with QoL at either T1 or T2. QoL and depression at T1 were identified as the strongest predictors of QoL at T2 (six years later).

DISCUSSION

The current study supports previous research highlighting the importance of psychological factors in understating QoL in PWE, particularly stigma, anxiety, and depression. In particular, it highlights the impact of depression on QoL over a 6-year interval, providing evident for the long-term nature of this relationship.

Access to healthcare and prevalence of anxiety and depression in persons with epilepsy during the COVID-19 pandemic: A multicountry online survey

OBJECTIVE

The objective of this study was to assess access to healthcare and to estimate the prevalence of depression and anxiety among persons with epilepsy (PWE) during the ongoing coronavirus disease 2019 (COVID-19) pandemic.

METHODS

We conducted a multicountry online survey among PWE. Persons with epilepsy were invited to participate through various social media channels. The Hospital Anxiety and Depression Scale (HADS) and 9-item Patient Health Questionnaire (PHQ-9) scale were used to score anxiety and depression. Logistic regression modeling was used to investigate factors associated with anxiety and depression.

RESULTS

Three hundred ninety-nine PWE were included (mean age: 38.22 ± 12.09 years), the majority were female (80.2%) and living in high-income countries (83.2%). Two hundred three PWE reported symptoms of a cold since January 2020. Nine (25%) of the 36 PWE tested for COVID were positive. A total of 72 PWE (19.6%) reported problems to obtain antiseizure medication (ASM), which in 25% of cases was directly COVID-related. Of the 399 PWE, 201 (50.4%) screened positive for anxiety according to the HADS; 159 (39.8%) and 187 (46.9%) PWE screened positive for depression based on the HADS and PHQ-9 scale, respectively. Female gender and financial problems were associated with both depression and anxiety. A planned follow-up consultation with the treating physician was associated with a lower risk of depression, whereas difficulties to access ASM treatment increased the odds of depression. In 65/137 (47.4%) PWE with a planned follow-up visit with the treating physician, this consultation was canceled.

CONCLUSIONS

Innovative approaches are needed to ensure continuity in access to ASM treatment. Healthcare workers should ensure continued follow-up, either through inperson or telehealth appointments, to timely identify symptoms of anxiety and depression and act accordingly.

Quality of life perception in patients with epilepsy for a period of 4 years

The quality of life (QoL) perception over time in adult people with epilepsy (PWE) is important to define strategies of conduct.

OBJECTIVE

The aim of this study was to assess the minimally important change (MIC) threshold of the Quality of Life in Epilepsy Inventory-31 (QOLIE-31) of PWE over a period of 4 years and its relationship with clinical epilepsy variables.

METHODS

A total of 129 PWE (46 ± 14.3 years) were included, and the clinical aspects of epilepsy and the QOLIE-31 were assessed in the initial and final assessment, with p < 0.05.

RESULTS

The emotional well-being (-6.31) and social functioning (-5.36) showed clinically relevant effects between the assessments. Quality of life was compromised by increasing the number of antiepileptic drugs (AED) taken [total score (-8.53), social functioning (-14.70)] or by maintaining the use of polytherapy [social functioning (-12.89)]. Fewer seizures were associated with a better QoL [total score (7.99), social (17.88) and cognitive functioning (16.30)]. The reduction in seizures was not associated with a better QoL [total and social functioning score], and the increase in seizures did not change QoL perception (cognitive functioning). There was a reduction in the QoL perception in medication effects in temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) (8.92) and with an increase in age in one year (-0.44).

CONCLUSIONS

Quality of life was compromised in the emotional well-being and social functioning during the 4-year follow-up period. The increase in the number of AED taken and age and the TLE-HS compromised QoL changes in the frequency of seizures not associated with a significant improvement in QoL.

Factors related to the adverse events of antiepileptic drugs

OBJECTIVE

The aim of the present study was to explore the factors related to the severity of the adverse effects of antiepileptic drugs (AEDs), experienced by patients with epilepsy.

MATERIALS AND METHODS

A case study was conducted in adult patients with epilepsy and followed up at the Epilepsy Outpatients of the University Hospital of Ioannina in Northwest Greece. The Adverse Event Profile (AEP) questionnaire for AEDs adverse effects assessment, the Defense style questionnaire (DSQ-88) and the Patient Health Questionnaire (PHQ-9) for depression' severity evaluation were used to estimate the severity of adverse effects, the defense style, and the depressive symptoms, respectively.

RESULTS

Sixty-three patients with epilepsy (M/F:28/35), with a mean age of 37.6 ± 13.41, were recruited in the study. The univariate analysis showed that both the Maladaptive style of defense and the PHQ-9 score were significantly associated with the AEP score. After multivariate regression analysis female gender, the load of AEDs, the PHQ-9 score, and the Adaptive defense style remained significant coefficients.

CONCLUSION

There are also nonpharmacological factors that may contribute to the severity of the adverse effects of AEDs, experienced by the patients with epilepsy.

Comparing eating behaviours, and symptoms of depression and anxiety between Spain and Greece during the COVID-19 outbreak: Cross-sectional analysis of two different confinement strategies

OBJECTIVE

We compared eating behaviours, and depressive and anxiety symptoms in two countries with different confinement strictness strategies and different levels of COVID-19 pandemic.

METHOD

A web-based cross-sectional survey was administered during and shortly after the COVID-19 related lockdown in Spain and Greece. Multivariable linear regression analyses were performed to identify country differences associated with eating behaviour, and symptoms of depression and anxiety.

RESULTS

This study included 1,002 responders in Spain and 839 in Greece. The mean ± SD of restraint, emotional and external eating was 2.5 ± 0.79, 2.1 ± 0.81 and 2.6 ± 0.65 in Spain, whereas 2.7 ± 0.85, 2.3 ± 0.99 and 2.9 ± 0.74 in Greece. Spanish participants had lower average scores of restraint and external eating compared to Greek participants (p < .001), but no difference was seen for emotional eating. In Spain, 13.6%, and 12.3% of the survey respondents reported moderate to severe depressive and anxiety symptoms, respectively, whereas in Greece the respective values were 18.8 and 13.2%. After adjusting for several risk factors, a higher prevalence of anxiety symptoms was observed in Spain compared to Greece (p = .001), but no difference was seen for depressive symptoms.

CONCLUSIONS

This study demonstrated high scores of inappropriate eating behaviours and a high frequency of depressive and anxiety symptoms in two Mediterranean countries during the COVID-19 outbreak. Our findings revealed that compared to Greek participants, Spanish participants, that faced more severe COVID-19 pandemic and stricter lockdown measures, were associated with lower restraint and external eating and increased anxiety symptoms, but not with depressive symptoms or emotional eating.

Negative emotions and quality of life among adolescents: A moderated mediation model

Background/Objective

Depression, anxiety and stress are known as negative emotions. Previous studies have shown that negative emotions were associated with quality of life. There are a lot of researches on quality of life. However, previous studies mainly focused on health-related quality of life among patients. This study aims to examine the relationship between negative emotions and quality of life as well as the underlying psychological mechanism among community-based samples.

Method

We surveyed 6,401 adolescents (age: 9-15 years old). Participants were assessed using the Depression Anxiety Stress Scale, Resilience Scale for Chinese Adolescent, Perceived Social Support Scale and the Pediatric Quality of Life Inventory 4.0 Generic Scale for Negative Emotions, Resilience, Social Support and Quality of Life.

Results

Results revealed that negative emotions were negatively associated with quality of life, and resilience mediated the relationship between negative emotions and quality of life. Social support moderated all the paths among negative emotions, resilience and quality of life.

Conclusions

Adolescents’ quality of life was indirectly affected by negative emotions via resilience, and less affected by negative emotions and more affected by resilience with the improvement of social support. The theoretical and practical implications of these results are discussed.

Comparison of Health-Related-Quality-of-Life among Children with Epilepsy and a Healthy Control Group in Tehran

The objective of this study was to determine the quality-of-life (QoL) among children with epilepsy in comparison with a healthy control group. Participants included mothers of 206 children with epilepsy and of 211 healthy controls. The QoL was measured via cross-cultural adaptation of the Quality-of-Life in Children with Epilepsy Questionnaire, which was also modified for the control group. The mean (standard deviation) overall QoL score of children with epilepsy was lower than that of the healthy control group at: 74.3 (8.2) versus 87.9 (6.6), p < 0.001. In addition, all seven dimensions of QoL were lower among children with epilepsy compared with that of the healthy control group. The health-related QoL of children with epilepsy was lower than that of the healthy control group. Children experiencing seizures more frequently, experiencing side effects from antiepileptic drugs, having a history of hospitalization, and having poor school performance displayed lower scores in QoL, which may highlight the impact of the severity of the disease and proper management of seizures on the quality-of-life in children with epilepsy.

Validity and reliability of the Turkish version of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E)

The aim of this study was to test the validity and reliability of the Turkish version of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), which was developed to rapidly investigate depressive symptoms in patients with epilepsy. A consecutive sample of 51 patients with epilepsy was included in the study. The Beck Depression Inventory (BDI) and the Turkish version of the NDDI-E were applied to the participants. During the application, it was observed that the participants could quickly fill the scale without any difficulties in understanding the translated items. The Cronbach's α coefficient was 0.721. Receiver operating characteristic analysis showed an area under the curve of 0.902 (95% confidence interval [CI] = 0.822-0.983), a cutoff score of >15, a sensitivity of 88.2%, a specificity of 82.4%, a positive predictive value of 71.4%, a negative predictive value of 93.3%. The NDDI-E Turkish version scores were significantly and positively correlated with those of the BDI (Spearman's ρ = 0.832, p < 0.001). In conclusion, it has been determined that the Turkish version of the NDDI-E can be used as a valid and reliable measurement tool to detect major depression in Turkish people with epilepsy.
