Cross-cultural differences in levels of knowledge about epilepsy.

PURPOSE: To study how much people with epilepsy in Europe know and understand about their condition and how this might affect their lives. METHODS: Clinical, demographic, psychosocial details and information assessing knowledge were collected by using self-completion questionnaires mailed to members of epilepsy support groups. RESULTS: Data were collected from 6,156 people with epilepsy from ten European countries. There were significant between-country differences in all variables considered. Overall levels of knowledge were acceptable when measured by the epilepsy knowledge questionnaire (EKQ, medical items). However, there were some gaps in knowledge, particularly in issues relating to medication and cause of epilepsy. CONCLUSIONS: This is the largest study of its kind to date. Results clearly highlighted that levels of knowledge differed significantly between countries. Overall, people with epilepsy are reasonably well informed about epilepsy, although some gaps in knowledge were evident.

Development of a new seizure severity questionnaire: initial reliability and validity testing.

PURPOSE: This report describes the initial steps for development of a new scale to assess seizure severity as a treatment response. METHODS: Standard methodology was used to develop the test instrument. Item generation was performed by selecting items from other questionnaires, and asking patients and epileptologists about seizure components. Face and content validity were assessed in a pilot study with patients and observers. The questionnaire was formatted as a structured interview for a reliability study. Construct validity was assessed with three existing questionnaires. Inter-rater reliability and test-retest reliability were performed as two independent ratings on one day, and one re-interview. RESULTS: Based on item generation and pilot testing (33 patients, 28 observers), the Seizure Severity Questionnaire (SSQ) was organized into warning, activity-movement, and recovery (cognitive, emotional, and physical aspects) stages of seizures. Questions reviewed duration, severity, bothersomeness and overall ratings, and the most bothersome aspect of seizures. The mean SSQ Summary Score was 5.78+/-3.24, inter-rater reliability was 0.76 (N=91), and test-retest reliability was 0.74 (N=63). Construct validity showed statistically significant correlations with other scales. CONCLUSION: This study has explored the psychometric properties of the SSQ for face and content validity, inter-rater and test-retest reliability, and construct validity. The Summary Score reliably represents the major components of seizures.

The effects of adjunctive topiramate therapy on seizure severity and health-related quality of life in patients with refractory epilepsy---a Canadian study.

Although reduction in seizure frequency is the most common endpoint used to assess the antiepileptic efficacy, seizure frequency alone does not provide a complete picture of effectiveness, particularly in patients with refractory epilepsy. The aim of our study was to assess the effects of topiramate on seizure severity and health-related quality of life (HRQL), in addition to standard efficacy measures, in an open, multicentre, 6-month trial of patients with epilepsy uncontrolled on antiepileptic drugs other than topiramate. Two hundred and nine patients were enrolled and received topiramate for up to 6 months (initiated at 50 mg/day and titrated to a recommended dose of 200-400 mg/day) in addition to existing medication. The median reduction in seizure frequency from baseline to the post-titration period was 40.9% ( P< 0.0001). Patients also demonstrated a mean reduction in the Liverpool Seizure Severity Scale (LSSS) of 5.3 ( P< 0.0001), which was considered clinically significant. Statistically significant changes in HRQL were not observed with the SF-36, a generic measure. Tolerability of antiepileptic medication was good, with a low incidence of cognitive adverse events. The results indicate that topiramate significantly reduces seizure severity---an important aspect of HRQL---when administered as adjunctive therapy to anticonvulsant therapy.

A review of neuropsychological services in the United Kingdom for patients being considered for epilepsy surgery.

We report a review of the current practice of neuropsychologists working within epilepsy surgery services. The aim of the review was to examine areas of diversity and consensus across current national service provision and to examine progress in service delivery since a previous survey in 1994. Sixteen centres provided information via a questionnaire on three areas of clinical practice: pre- and post-surgery neuropsychological protocols; the intracarotid sodium amytal protocol; patient and family expectations and psychological health, in addition to examining aspects of the context of clinical practice such as the role and experience of the psychologist and future service priorities. Findings of the review suggest that, whilst progress has been made towards fulfilling the recommended guidelines for services, there remain a number of areas for development in terms of the provision of a consistent nationwide service delivery approach. Cognitive assessment and the ICSA procedure remain essential components of the neuropsychology service. Assessment of psychological health and quality of life is now carried out by a growing number of centres, although these remain areas for further development. Consensus was found in terms of the need to establish centres of excellence, and to develop appropriate training for neuropsychologists in the field.

The neuropsychological and emotional consequences of living with intractable temporal lobe epilepsy: implications for clinical management.

PURPOSE: To investigate and document the neuropsychological and emotional effects of epilepsy in people with intractable temporal lobe epilepsy (TLE). METHODS: 273 patients with a diagnosis of TLE underwent a complete neuropsychological and psychological examination as a routine part of their investigation for epilepsy surgery. Neuropsychological assessment included measures of intellect, memory, language functioning, higher executive functioning, emotional well-being and the psychosocial impact of epilepsy and its treatment. RESULTS: The sample comprised 135 females and 138 males with a clearly lateralised epileptogenic focus. Patients were mildly anxious but not depressed, although many reported that epilepsy and its treatment had a marked effect on their daily lives. Current reading ability was in the average range; the mean obtained full scale IQ was 88 (low average range). Verbal memory functioning was within the borderline impaired range with visual memory functioning within the average range. Mean language performance was between the 5-10th percentile. Higher executive functioning results were in the normal range. Multiple univariate analyses were performed according to onset laterality. There were no significant differences between the groups on measures of psychological or emotional functioning. Participants with left TLE scored significantly lower than those in the right temporal group on measures of verbal intelligence, general intelligence, attention span and expressive language functioning. CONCLUSIONS: Patients with intractable epilepsy suffer significant neuropsychological difficulties in terms of their intellect, memory and language. Higher executive functioning appears unaffected. In addition, there is also evidence of emotional distress. These all impact upon their day-to-day functioning, which can be improved by the application of various psychological therapies and interventions.

[Level of knowledge about epilepsy among Polish patients with epilepsy and their families in the European study SPOKE (Sanofi-Synthelabo Programme for Outcome Knowledge of Epilepsy)].

BACKGROUND AND PURPOSE: The main aim of the European Study SPOKE (Sanofi-Synthelabo Programme for Outcome Knowledge of Epilepsy) designed by the Department of Neurosciences, Walton Hospital in Liverpool and the Centre for Health Services Research at the University of Newcastle upon Tyne, England, was to describe levels of knowledge about epilepsy among people with epilepsy and their families. It was equally important to identify gaps in understanding the most important aspects of the illness as well as to identify characteristics of people who score poorly on the Epilepsy Knowledge Questionnaire (EKQ). Another aim was to consider the implications of identified gaps in knowledge for future educational and psychosocial interventions. MATERIAL AND METHODS: The study was conducted in 10 European countries and included 6156 people with epilepsy and 6506 members of their families. Results presented here relate to data for Poland only, where the examined population consisted of 1028 patients with epilepsy. 1033 questionnaires were returned by carers. RESULTS: Over 40% of all respondents had frequent seizures, and one third were seizure free. Scores on the Epilepsy Knowledge Questionnaire were high for the majority of respondents, but generally lower than in most of the countries. With reference to some aspects of illness important gaps in knowledge have been demonstrated. For example, it was shown that a significant number of respondents provided incorrect answers to questions relating to aspects of the etiology of epilepsy and administration of antiepileptic drug medication. There were a number of significant differences between the profiles of high and low scorers on the EKQ; high scorers were likely to have spent longer on education, have lower scores on the impact of epilepsy scale and report better adjustment to their epilepsy. CONCLUSIONS: The results of the study once again underline the importance of continued information among patients with epilepsy and their families in order to achieve.
