The purpose of this paper was to investigate the contributions of sociodemographic, neurologic, and neuropsychological variables to health-related quality of life (HRQoL) in children with epilepsy and high seizure burden. Focus was placed on the relationship between memory and HRQoL, which has not been previously investigated.

Ninety children with epilepsy receiving clinical care at a tertiary-level children's hospital were retrospectively identified. Primary assessment measures were verbal memory (California Verbal Learning Test-Children's Version) and HRQoL. Other neuropsychological variables included intellectual function, executive function, emotional and behavioral function, and adaptive function. Sociodemographic and neurologic variables were extracted from chart review.

No significant correlations were found between HRQoL and sociodemographic or neurologic variables. Moderate correlations were found between neuropsychological variables and HRQoL. Emotional function (Child Behavior Checklist) and verbal memory (California Verbal Learning Test-Children's Version) emerged as significant predictor variables of HRQoL. Low verbal memory was associated with a twofold risk of low HRQoL, emotional and behavioral difficulty with a 10-fold risk, and the combination of emotional and behavioral difficulty and low verbal memory with a 17-fold risk.

Verbal memory and emotional and behavioral difficulty are associated with increased risk of low HRQoL, even when other important variables are considered in children with high seizure burden. The results reinforce the importance of neuropsychological assessment in clinical care in pediatric epilepsy and suggest important areas of focus for psychological intervention.

    ABSTRACT: Purpose: The primary objective of the study was to explore the barriers that volunteers face and the strategies they employ when teaching blind children via Skype. It also attempted to understand the difference in methodologies used in teaching blind children and other underprivileged children. Method: In February and March 2013 an online survey was conducted with 8 volunteer teachers who work with two development programmes in South India, supported by the Ann Foundation, a non-government organisation based in New York, United States. Results: Volunteers find that teaching blind children through Skype is challenging as well as rewarding. Poor internet connectivity in the remote villages of the country is a major technical barrier. The interaction barriers are lack of advanced learning devices and specific teaching expertise to maintain the children's interest in learning. Strategies to enhance learning among the blind children included the use of contemporary topics, fun activities, songs and storytelling. Conclusion: There are a unique set of barriers when teaching blind children through Skype. While most of these can be overcome with facilitatory learning approaches, volunteer teachers continue to struggle with the barriers of poor internet connectivity and reluctance on the part of blind students to participate in the class. Limitations: The sample size was small, numbering only 8 volunteers who, however, provided many insights. Since they were based in different parts of the world, it was not possible to conduct one-to-one interviews, which might have yielded more information.

    ABSTRACT: Objective: To explore the characteristics of ecological executive function in young adults with idiopathic or probably symptomatic epilepsy and examine the effects of executive function on quality of life. Methods: Fifty-five epileptics (EP) and 39 matched healthy controls (HC) aged 18-44 years at our hospital were selected. The differences in ecological executive function and quality of life were compared between two groups with the Behavior Rating Inventory of Executive Function-adult version (BRIEF-A) and QOLIE-31. Results: Comparing with controls, the epileptics yielded higher scores significantly on most subscales of BRIEF-A (P < 0.05), including total score [(55 ± 9) vs (48 ± 7)], inhibition [(54 ± 7) vs (48 ± 7)], emotion control [(56 ± 8) vs (49 ± 7)], self-monitor [(54 ± 10) vs (47 ± 7)], initiation [(51 ± 10) vs (46 ± 9)], working memory [(56 ± 10) vs (50 ± 9)], planning [(53 ± 10) vs (47 ± 7)], behavioral regulation index (BRI) and metacognition index (MI). Pearson's correlation test showed that the total score of QOLIE-31 had significantly negative correlations with the scores of BRIEF-A, such as global executive composite (GEC), behavioral regulation index (BRI), metacogniton index (MI), inhibition, emotional control, monitoring, initiation and working memory (r = -0.284- -0.457, P < 0.05). Moreover, seizure control and seizure type were also related with the total score of QOLIE-31(r = -0.302, r = 0.268, P < 0.05). Multiple stepwise regression analysis showed that emotional control in BRIEF-A was related with seizure worry and cognitive function in QOLIE-31(t = -2.137, t = -2.427, P < 0.05) . Behavioral regulation index (BRI) was closely related with emotional well-being in QOLIE-31(t = -2.148, P < 0.05). Also, working memory was related with cognitive function, overall quality of life and total score in QOLIE-31(t = -3.138, -3.564, -2.948, P < 0.05). And inhibition was related with energy, social function and total score in QOLIE-31(t = -3.007, -3.580, -2.191, P < 0.05). Conclusion: Young adults with idiopathic or probably symptomatic epilepsy may have significant executive function impairment. The aspects of emotional control, BRI, working memory and inhibition in ecological executive function are significantly related with quality of life in epilepsy.

    ABSTRACT: INTRODUCTION. Epilepsy is a chronic neurological syndrome that is accompanied by abnormal, synchronic and exaggerated discharges in the cerebral cortex. Epilepsy is inversely related to health-related quality of life (HRQL), although little has been published on this relationship in children in Latin America. AIM. To examine the relation between epilepsy and HRQL in a group of schoolchildren aged 8-12 years who were treated in a paediatric hospital in Sonora, Mexico. PATIENTS AND METHODS. A cross-sectional study was conducted to compare the HRQL of children diagnosed with epilepsy with respect to the HRQL of two control groups. The validated questionnaire Paediatric Quality of Life Inventory was used to evaluate HRQL. Differences were examined by means of an ANOVA test and the association between epilepsy and HRQL was modelled by means of multiple logistic regression. RESULTS. The children with epilepsy displayed the lowest HRQL score (62.4 ± 14.8) of the subjects studied and had 5.2 times as much risk of their HRQL deteriorating (95% confidence interval = 2.43-11.06) compared to healthy children. Deterioration was greater on the cognitive (54.6 ± 15.0) and emotional scales (55.9 ± 23.6). Polypharmacy, i.e. the concomitant ingestion of three or more drugs (p < 0.001), and the chronological progression of suffering (p < 0.001) are factors that significantly deteriorate the HRQL of children with epilepsy. CONCLUSIONS. Epilepsy gives rise to an overall deterioration in the HRQL of children, specifically in the cognitive and emotional spheres, which is related with the chronological progression of the disease and polypharmacy.
