Quality of life in epilepsy

Outcomes of epilepsy surgery in adults and children

Surgery is widely accepted as an effective therapy for selected individuals with medically refractory epilepsy. Numerous studies in the past 20 years have reported seizure freedom for at least 1 year in 53-84% of patients after anteromesial temporal lobe resections for mesial temporal lobe sclerosis, in 66-100% of patients with dual pathology, in 36-76% of patients with localised neocortical epilepsy, and in 43-79% of patients after hemispherectomies. Reported rates for non-resective surgery have been less impressive in terms of seizure freedom; however, the benefit is more apparent when reported in terms of significant seizure reductions. In this Review, we consider the outcomes of surgery in adults and children with epilepsy and review studies of neurological and cognitive sequelae, psychiatric and behavioural outcomes, and overall health-related quality of life.

Self-proxy agreement and correlates of health-related quality of life in young adults with epilepsy and mild intellectual disabilities

This study investigated health-related quality of life (HRQOL) in young adults with epilepsy and intellectual disabilities. First, agreement between self-reports and proxy reports of HRQOL was examined. Second, medical and psychological contributions to HRQOL were explored. Thirty-six patients were interviewed using the Quality of Life in Epilepsy inventory (QOLIE-31), the Hospital Anxiety and Depression Scale, and the Neuroticism and Extraversion scales of the NEO Five-Factor Inventory. Medical data were taken from files. Professional caregivers completed rephrased QOLIE-31-questionnaires. The perspectives on HRQOL differed systematically: Caregivers underrated their clients' HRQOL on average. Few correlations with medical characteristics emerged, whereas all psychological variables were strongly related to HRQOL. Neuroticism, Age at Disability Onset, and their interaction explained 71% of the HRQOL variance. Results indicate that proxy reports do not provide valid substitutes for most of the self-reported HRQOL subscales. Psychological treatment of negative affectivity and after critical life events in adolescence may improve HRQOL in young adults with epilepsy and mild intellectual disabilities.

Quality of life among people with epilepsy and mild intellectual disabilities in residential care

This study examined quality-of-life (QOL) evaluations among people with epilepsy and mild intellectual disabilities in residential care to determine their covariation and potential determinants. Participants were 111 clients of the Bethel Institute, Bielefeld, Germany. They completed questionnaires on their overall QOL and life satisfaction, the PESOS scales on epilepsy-related QOL, the Brief Symptom Inventory (BSI), and scales on activities of daily life and work-related problems in face-to-face-interviews. QOL evaluations differed in the various domains and tended to be better on more concrete items. Correlations of generic QOL parameters with scales on epilepsy-related QOL were only weak. BSI scores reflecting the current emotional state were identified as the most influential predictors of all QOL measures. The weak relationship between non-health-related parameters of subjective QOL and epilepsy-related QOL requires further investigation and theoretical explanation, whereas the influence of negative affect on different QOL dimensions is in line with previous QOL findings.

I just want to be normal: a qualitative study exploring how children and adolescents view the impact of intractable epilepsy on their quality of life

This qualitative study explores how children and adolescents with medically refractory seizures experience the impact of epilepsy on their quality of life (QOL) within the domains of physical, emotional/behavioral, social, and cognitive/academic function. Semi-structured, open-ended interviews were conducted with 49 participants (7-18 years old). These narratives constituted our data source. Analyses involved inductive generation of themes/subthemes and connection of these themes to generate a theoretical representation of their relationships. These themes reflected the negative impact of epilepsy on QOL: physical-excessive fatigue as a barrier to academic and social pursuits; emotional/behavioral-intermittent emotional distress heightened by epilepsy-related factors such as unpredictability of seizures; social-profound social isolation; and cognitive/academic-discontinuous, fragmented learning. Youths perceive seizures as the major barrier to their sense of normalcy, setting them apart from others. Findings provide direction for assessment and evidence for developing or enhancing clinical interventions and community/school-based programs that might mitigate some of these negative experiences.

Cognitive, Psychosocial, and Family Function One Year after Pediatric Epilepsy Surgery

PURPOSE

Assumptions regarding the benefits of seizure control after pediatric epilepsy surgery for cognitive, psychosocial, and family function were explored in a prospective study of 51 children with intractable epilepsy.

METHODS

Thirty children who underwent surgery were studied before and 1 year after surgery, and a comparison group of 21 children with medically refractory seizures was examined at comparable times.

RESULTS

One year after surgery, 57% of the surgical group was seizure free. Seizure status after surgery did not predict change over time in any of the areas measured. Cognitive and psychosocial status did not change over time in either group, and the strongest predictor of individual change in psychosocial status in the surgical group was baseline level of function. Within the surgical group, a trend toward an increase in independence promotion was noted in the family, but the children's satisfaction with the family declined.

CONCLUSIONS

These findings challenge the assumption that elimination of seizures will result in improved cognitive, psychosocial, and family functioning, at least within the first year after surgery.

Coping with Parkinson's disease and refractory epilepsy. A comparative study

Coping strategies and their correlations with demographic and illness related data, depression, locus of control, and psychosocial adaptation were investigated in 45 patients with Parkinson's disease and 40 patients with intractable epilepsy. Three standardized self-report questionnaires were applied: the Freiburg Questionnaire of Coping with Illness (FKV), the von Zerssen Depression Scale (D-S), and the IPC-questionnaire measuring generalized locus of control beliefs. The Social Interview Schedule (SIS), a semi-structured interview, was used to measure psychosocial adaptation. Active, problem-focused and compliance strategies were predominantly used and regarded as most helpful in both groups of patients. Hence, Parkinson and epilepsy patients used similar coping patterns despite the strong dissimilarities of symptoms and illness-associated burdens. The level of depression was not significantly different in both groups and in the range of other chronic somatic diseases. The use of coping patterns, which are regarded as maladaptive, was correlated with distinct depression and a poor psychosocial adaption. In conclusion, no indications for illness-specific coping patterns were found in patients with Parkinson's disease and epilepsy. In both groups, certain coping strategies are associated with good and others with poor psychosocial adjustment. These results indicate the possibility of improving psychosocial adjustment by supporting effective strategies.
