Age-specific incidence and prevalence rates of treated epilepsy in an unselected population of 2,052,922 and age-specific fertility rates of women with epilepsy.

BACKGROUND: There are no data on prevalence or incidence of treated epilepsy, and no data on fertility of women with epilepsy from an unselected UK population. METHODS: We used the General Practice Research Database to ascertain the incidence and prevalence of people with treated epilepsy in an unselected population of 2,052,922 people in England and Wales, and also age-specific fertility rates. We defined period prevalence of treated epilepsy as the number of people with epilepsy taking an antiepileptic drug per 100,000 people during 1995. The incidence of treated epilepsy was defined as the number of new cases of treated epilepsy per 100,000 people during the same period. We calculated fertility rates among women with treated epilepsy between 1991 and 1995 and compared these rates with the population rates for England and Wales in 1993. FINDINGS: The period prevalence of treated epilepsy in 1995 was 5.15 per 1000 people (95% CI 5.05-5.25). The prevalence was lower in children (age 5-9 years 3.16 [2.86-3.48]; 10-14 years 4.05 [3.70-4.42]), and higher in older people (65-69 years 6.01 [5.50-6.57]; 70-74 years 6.53 [5.97-7.14]; 75-79 years 7.39 [6.73-8.11]); 80-84 years 7.54 [6.78-8.39]; 85 years and older 7.73 [6.98-8.66]). The incidence of treated epilepsy was 80.8 per 100,000 people (76.9-84.7). The incidence was lower in children (5-9 years 63.2 [50.5-79.1]; 10-14 years 53.8 [42.4-68.3]) and higher in older people (65-69 years 85.9 [68.5-107.3]; 70-74 years 82.8 [65.0-105.2]; 75-79 years 114.5 [116.9-179.2]; 80-84 years 159 [125.2-202.6]; > or = 85 years 135.4 [100.4-178.7]). Fertility was lower among women with treated epilepsy, with an overall rate of 47.1 livebirths per 1000 women aged 15-44 per year (42.3-52.2), compared with a national rate of 62.6 in the same age-group. The standardised fertility ratios were significantly lower between the ages of 25 and 39 years in women with epilepsy (p<0.001). INTERPRETATION: Compared with previous studies, we found that the incidence of epilepsy was higher in elderly people and lower in children. The prevalence rates also increase with age. Women aged 25-39 years with treated epilepsy have significantly lower fertility rates than those in the general population. Research is needed to identify any potentially preventable causes for the low fertility rates.

Epilepsy surgery, delays and referral patterns-are all your epilepsy patients controlled?

RATIONALE: Epilepsy surgery is a standard of care in the treatment of medically intractable epilepsy, but is underutilised. We describe the results of epilepsy surgery and the referral patterns at a referral epilepsy programme. METHODS: We reviewed the outcome of epilepsy surgery performed at the University of South Florida and Tampa General Hospital epilepsy programme for the years 2000 and 2001. The typical presurgical evaluation included clinical evaluation, EEG-video monitoring, MRI with dedicated epilepsy protocol, PET, SPECT, neuropsychological testing and Wada testing. We used the Engel outcome classification, and focused on the referral information to determine how and when in the course of their illness patients arrive at a referral epilepsy centre. RESULTS: In the 2-year period (2000-2001), a total of 36 epilepsy surgeries were performed. Twenty-nine temporal lobectomies, six extratemporal resections and one corpus callosotomy. Ages varied from 17 to 65 years. Overall results were: 30 (83%) seizure-free [class I], 5 (17%) rare seizures or almost seizure-free [class II] and 1 no improvement. Of the 29 temporal lobectomies, 27 (93%) are completely seizure-free [class I] and 2 (7%) are >90% improved [class II]. Duration of seizures before being seen at the epilepsy centre averaged 18 years (range 2-58 years). Twenty-two (61%) were sent by their neurologists, while 14 (39%) came self-referred without having discussed surgery with their neurologists. Five (14%) were specifically advised by their neurologist to not consider surgery. Two had participated in clinical trials of antiepileptic drugs (AEDs) before being seen at the epilepsy centre. CONCLUSIONS: Epilepsy surgery has high efficacy and very low morbidity. Yet, there continues to be a long delay in the referral of patients to the epilepsy centre, suggesting that surgery for epilepsy is underutilised.

Mortality of epilepsy from national vital statistics and University epilepsy clinic in Taiwan.

PURPOSE: Where population-based studies of epilepsy mortality are impossible to conduct, other sources of data must be considered. We provide descriptive data on mortality and causes of death for epilepsy in Taiwan. METHODS: Two settings in Taiwan were used. First, we evaluated the mortality ratio for epilepsy, using the national vital statistics for 1996 with the total population of Taiwan as the denominator. Second, we evaluated mortality in a cohort of prevalent epilepsy cases from a University outpatient clinic. For both, proportionate mortality was calculated to determine the relative contributions of different causes of death in epilepsy. RESULTS: One hundred and sixty-two deaths were correctly coded under ICD code 345 from the 1975 detailed diagnostic listing during the 1-year period of 1996. Epilepsy was the diagnosis in 0.8 deaths/100,000 population. Over an 11-year period, there were 54 deaths (0.9%) among 1,224 prevalent epilepsy cases from a University clinic during 5,704 person-years of follow-up. The most common underlying cause of death was epilepsy-related death in 129 (79.6%) out of 162 deaths from the vital statistics data. There were 13 deaths unrelated to epilepsy (8.0%). Acute reactive seizure as the cause of death was found in 9 patients (5.6%). The leading cause of death in the epilepsy clinic was disease unrelated to epilepsy in 21 deaths (38.9%), epilepsy-related death in 12 patients (22.2%), and death related to the cause of epilepsy in 9 patients (16.7%). CONCLUSION: Data derived from vital statistics are inadequate to evaluate mortality in people with epilepsy.

Psychological treatments for epilepsy.

BACKGROUND: Psychological interventions such as relaxation therapy, cognitive behaviour therapy, EEG bio-feedback and educational interventions have been used alone or in combination in the treatment of epilepsy, to reduce the seizure frequency and improve the quality of life. OBJECTIVES: To assess whether the treatment of epilepsy with psychological methods is effective in reducing seizure frequency and/or leads to a better quality of life. SEARCH STRATEGY: We searched the Cochrane Epilepsy Group trial register, the Cochrane Controlled Trials Register (Cochrane Library Issue 2, 2001), MEDLINE using OVID (1966 - May 2001) and cross references from identified publications. SELECTION CRITERIA: Randomized or quasi-randomized studies assessing one or more types of psychological or behaviour modification techniques for patients with epilepsy. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the trials for inclusion and extracted data. Primary analyses were by intention to treat. Outcomes included reduction in seizure frequency, and quality of life. MAIN RESULTS: We found three small trials (50 patients) of relaxation therapy. They were of poor methodological quality and a meta-analysis was therefore not undertaken. No study found a significant effect of relaxation therapy on seizure frequency. One trial found cognitive behavioural therapy to be effective in reducing depression, among people with epilepsy with a depressed affect, whilst another did not. One trial of group cognitive therapy found no significant effect on seizure frequency. Two trials of combined relaxation and behaviour therapy and one of EEG bio-feedback and two of educational interventions did not provide sufficient information to assess their effect on seizure frequency. Combined use of relaxation and behaviour modification was found beneficial for anxiety and adjustment in one study. In one study EEG bio-feedback was found to improve the cognitive and motor functions in subjects with greatest seizure reduction. Educational interventions were found to be beneficial in improving the knowledge and understanding of epilepsy, improving compliance to medication and improving social competencies. REVIEWER'S CONCLUSIONS: In view of methodological deficiencies and limited number of patients studied, we have found no reliable evidence to support the use of these treatments and further trials are needed.

Syndromic diagnosis at the epilepsy clinic: role of MRI in lobar epilepsies.

PURPOSE: Magnetic resonance imaging (MRI) is an essential diagnostic tool for the management of epilepsy at modern epilepsy clinics. This study was conducted to incorporate MRI features into the international classification of epilepsies and epilepsy syndromes (ICEES) proposed by the International League Against Epilepsy (ILAE). METHODS: Three hundred consecutive patients newly registered in the Yonsei Epilepsy Clinic underwent stepwise classifications based on clinical features, clinical EEG, and clinical EEG-MRI correlations. The patients were required to have epilepsy and have undergone both EEG and MRI for inclusion in the study. Interictal epileptiform discharges (IEDs) in the EEG were divided into lobar, multilobar, and generalized. MRI lesions were divided into lobar and multilobar lesions. Lobar epilepsies (LEs) were divided into temporal, frontal, parietal, occipital, rolandic, temporoparietooccipital junctional, multilobar, and nonlocalized LEs. RESULTS: Two hundred forty-nine patients satisfied the inclusion criteria. In the first-step diagnosis, 190 patients were classified as having localization-related epilepsy; 24 patients, generalized epilepsy; 34 patients, undetermined epilepsy; and one patient, a special syndrome. EEG revealed IEDs in 124 (50%) patients, and the second-step diagnosis changed the diagnostic categories of 79 (32%) patients. MRI detected lesions in 106 (43%) patients, and the third-step diagnosis changed the diagnostic categories of 30 (12%) patients. The nonspecific diagnostic categories of ICEES decreased from 49% to 37% and then to 29%, as diagnosis progressed from steps one to three. In cases of LE, MRI was superior to EEG in its clinical correlation. Additionally, the diagnostic precision in temporal lobe epilepsy was far better than that for other LEs. CONCLUSIONS: The impact of MRI on ICEES was only modest in terms of changing diagnostic categories, although MRI provided a structural substrate for epilepsy in 38% of patients with negative EEGs. In LE, MRI was as sensitive as EEG, and its clinical correlation was superior to that of EEG, which strongly supports the rationale of incorporating MRI into ICEES.

Nonsymptomatic generalized epilepsy in children younger than six years: excellent prognosis, but classification should be reconsidered after follow-up: the Dutch Study of Epilepsy in Childhood.

PURPOSE: To assess the prognosis and the accuracy of the epilepsy classification in young children with nonsymptomatic generalized epilepsy. METHODS: Of the cohort of the Dutch Study of Epilepsy in Childhood (n = 466), all children younger than 6 years with a diagnosis of idiopathic (IGE) or cryptogenic (CGE) generalized epilepsy either at intake (n = 108) and/or after 2 years of follow-up (n = 102) were included. The number of reclassifications after 2 years was determined, and the reasons for reclassification were analyzed. All children receiving a diagnosis of IGE or CGE at 2 years were followed up for 5 years to study their outcome in terms of terminal remission (TR). Data on their level of intellectual functioning were collected at the start of this analysis. RESULTS: The epilepsy syndrome was reclassified in 17 children. In 14 of them, the seizure type also was reclassified, and in three, the course of the epilepsy determined the new epilepsy type. Two other children had a reclassification of their seizure types without a change of the epilepsy type. Many children were categorized as having IGE not otherwise specified. In all probability, this is a heterogeneous group, containing patients with various epilepsy syndromes, with generalized tonic-clonic seizures as a common hallmark. Of the 102 children with IGE or CGE at 2 years of follow-up, 75% had a TR of >6 months after 2 years, and 85% a TR of >or=1 year after 5 years. CONCLUSIONS: In a fair proportion of children with nonsymptomatic generalized epilepsy in this age group, it is not possible to classify firmly the epilepsy and/or the seizures immediately after the intake. Instead, they are reclassified during the course of the disease. This and the apparent heterogeneity of the category IGE not otherwise specified point to inherent drawbacks of the current International League Against Epilepsy (ILAE) classification of epilepsy and epileptic syndromes. The prognosis of IGE at this young age is generally excellent.

Interictal mood and personality disorders in temporal lobe epilepsy and juvenile myoclonic epilepsy.

BACKGROUND: Mood disorders have been described as the commonest psychiatric disorders in patients with temporal lobe epilepsy. Secondary depression in temporal lobe epilepsy could be interpreted either as an adjustment reaction to a chronic disease or as a limbic dysfunction. To clarify this issue, a controlled study of psychiatric disorders was conducted in different forms of epileptic and non-epileptic chronic conditions. METHODS: Twenty outpatients with temporal lobe epilepsy, 18 outpatients with juvenile myoclonic epilepsy--a primary generalised seizure disorder--20 matched type I diabetic patients, and 20 matched normal controls were assessed by a structured interview (SADS) and by self rating scales (Beck depression inventory (BDI) and the state and trait anxiety scales STAIX1 and STAIX2). RESULTS: Sixteen (80%) patients with temporal lobe epilepsy fulfilled the criteria for a psychiatric diagnosis at the SADS interview with a significantly higher frequency than patients with juvenile myoclonic epilepsy (22%) and diabetic patients (10%) (P < 0.0001). The most frequent disorder in temporal lobe epilepsy was a mood disorder: 11 (55%) patients with temporal lobe epilepsy had depression compared with three patients with juvenile myoclonic epilepsy and two diabetic patients (P < 0.001). Eight patients with temporal lobe epilepsy with an affective disorder also had a comorbid personality or anxiety disorder. Patients with temporal lobe epilepsy scored significantly higher on BDI, STAIX1, and STAIX2 than the three control groups (P < 0.001, P < 0.01, P < 0.001). CONCLUSIONS: Patients with temporal lobe epilepsy have a higher incidence of affective and personality disorders, often in comorbidity, than patients with juvenile myoclonic epilepsy and diabetic patients suggesting that these psychiatric disorders are not an adjustment reaction to a chronic disease but rather reflect a limbic dysfunction.

Epilepsy Care in the World: results of an ILAE/IBE/WHO Global Campaign Against Epilepsy survey.

PURPOSE: Information about existing resources available within the countries to tackle the huge medical, social, and economic burden caused by epilepsy is lacking. To fill this information gap, a survey of country resources available for epilepsy care was conducted within the framework of the ILAE/IBE/WHO Global Campaign Against Epilepsy. METHODS: The study represents a major collaborative effort involving the World Health Organization (WHO), the International League Against Epilepsy (ILAE) and the International Bureau for Epilepsy (IBE). RESULTS: Data were collected from 160 countries representing 97.5% of the world population. The information included availability, role, and involvement of professional and patient associations for epilepsy, epilepsy treatment and services including antiepileptic drugs, human resources involved in epilepsy care, teaching in epileptology, disability benefits, and problems encountered by people with epilepsy and health professionals involved in epilepsy care. The data confirm that epilepsy care is grossly inadequate compared with the needs in most countries. In addition, large inequities exist across regions and income groups of countries, with low-income countries having extremely meager resources. Complete results of this survey can be found in the Atlas: Epilepsy Care in the World. CONCLUSIONS: The data reinforce the need for urgent, substantial, and systematic action to enhance resources for epilepsy care, especially in low-income countries.

Yoga for epilepsy.

BACKGROUND: Stress is considered an important precipitating factor for seizures. Yoga is believed to induce relaxation and stress reduction. The effect of yoga on the EEG and the autonomic nervous system have been reported. Yoga would be an attractive therapeutic option for epilepsy (if proved effective), in view of its nonpharmacological nature, minimal side effects and international acceptance. OBJECTIVES: To assess the efficacy of yoga in the treatment of patients with epilepsy. SEARCH STRATEGY: We searched the Cochrane Epilepsy Group trial register, the Cochrane Controlled Trials Register (The Cochrane Library Issue 4, 1998), MEDLINE for articles published up to the middle of 1998, and also registries of the research council for complimentary medicine were searched. In addition, we searched the references of all the identified studies. Finally, we contacted the members of the Neurological Society of India, several neurophysiology institutions and yoga institutes to seek any ongoing studies or studies published in nonindexed journals or unpublished studies. SELECTION CRITERIA: Randomized control trials and controlled clinical trials of treatment of epilepsy with yoga. DATA COLLECTION AND ANALYSIS: The data were extracted independently by both reviewers and any discrepancies were resolved by discussion. The main outcomes assessed were percentage of patients rendered seizure free, number of patients with more than 50% reduction in seizure frequency or seizure duration and the overall reduction in seizure frequency. Analyses were on an intention to treat basis. MAIN RESULTS: Only one study met the selection criteria, and recruited a total of 32 patients, 10 to sahaja yoga and 22 to control treatments. Antiepileptic drugs were continued in all. Randomization was by roll of a dice. The results of this study are as follows: (i) Four patients treated with yoga were seizure free for six months compared to none in the control groups. The Odds Ratio (OR) (95% Confidence Interval (CI)) for yoga versus sham yoga group was 14.5 (0.7, 316.7) and for yoga versus no treatment group 17.3 (0.8, 373.5). (ii) Nine patients in the yoga group had more than 50% reduction in seizure frequency compared to only one among the controls. The OR (95% CI) for yoga versus sham yoga group was 81 (4.4, 1504.5) and for the yoga versus no treatment group was 158.3 (5.8, 4335.9). (iii) There was a decline in the average number of attacks per month compared to the baseline frequency among the patients treated with yoga. The weighted mean difference ( 95% CI) between yoga versus sham yoga group was -2.1 (-3.1, -1.0) and for the yoga versus no treatment group -1.1 (-1.8, -0.4). (iv) More than 50% reduction in seizure duration was found in seven of the 10 patients treated with yoga, compared to none among the 22 controls. The OR (95%CI) for yoga versus sham yoga group was 45 (2.0, 1006.8) and for yoga versus no treatment group 53.57 (2.4, 1187.3). REVIEWER'S CONCLUSIONS: No reliable conclusions can be drawn regarding the efficacy of yoga as a treatment for epilepsy. Further studies are necessary to evaluate the efficacy of yoga in the treatment of epilepsy.

Lamotrigine add-on for drug-resistant partial epilepsy.

BACKGROUND: Epilepsy is a common neurological disorder, affecting almost 0.5 to 1% of the population. Nearly 30% of patients with epilepsy are refractory to currently available drugs. Lamotrigine is one of the newer antiepileptic drugs and is the topic of this review. OBJECTIVES: To examine the effects of lamotrigine on seizures, side effects, cognition and quality of life, when used as an add-on treatment for patients with drug-resistant partial epilepsy. SEARCH STRATEGY: We searched the Cochrane Epilepsy Group trials register, the Cochrane Controlled Trials Register (Cochrane Library Issue 1, 2000), MEDLINE (January 1966 to December 1999) and reference lists of articles. We also contacted the manufacturers of lamotrigine (Glaxo-Wellcome). SELECTION CRITERIA: Randomized placebo controlled trials, of patients with drug-resistant partial epilepsy of any age, in which an adequate method of concealment of randomization was used. The studies may be double, single or unblinded. For crossover studies, the first treatment period was treated as a parallel trial. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the trials for inclusion and extracted data. Primary analyses were by intention to treat. Outcomes included 50% or greater reduction in seizure frequency, treatment withdrawal (any reason), side effects, effects on cognition, and quality of life. MAIN RESULTS: We found three parallel add-on studies and eight cross-over studies, which included 1243 patients (199 children and 1044 adults). The overall Peto's Odds Ratio (OR) and 95% confidence intervals (CIs) across all studies for 50% or greater reduction in seizure frequency was 2.71 (1.87, 3.91) indicating that lamotrigine is significantly more effective than placebo in reducing seizure frequency. The overall OR (95%CI) for treatment withdrawal (for any reason) is 1.12 (0.78, 1. 61). The 99% CIs for ataxia, dizziness, nausea, and diplopia do not include unity, indicating that they are significantly associated with lamotrigine. The limited data available preclude any conclusions about effects on cognition and quality of life, though there may be minor benefits in affect balance (happiness) and mastery. REVIEWER'S CONCLUSIONS: Lamotrigine add-on therapy is effective in reducing the seizure frequency, in patients with drug-resistant partial epilepsy. Further trials are needed to assess the long term effects of lamotrigine, and to compare it with other add-on drugs.

Long-term survival after epilepsy surgery compared with matched epilepsy controls and the general population.

This study evaluates if there was a difference in long-term survival between epilepsy surgery patients, individually matched controls with intractable epilepsy, and controls from the general population. In a cohort study, we compared the survival of patients operated with epilepsy surgery in Norway 1948-1988 with: (1) a control group with prolonged medical treatment for intractable epilepsy individually matched for age, gender, and seizure type (n = 139), and (2) expected mortality for matched individuals in historical cohorts of the general population (n = 196). Survival was compared using Kaplan-Meier curves and stratified proportional hazards analysis. After on average 25 years of observation after surgery, there was no difference in survival between the epilepsy surgery group and the controls with intractable epilepsy (p = 0.18). The risk ratio for death after epilepsy surgery was 0.6 (95% CI 0.4-1.1; p = 0.08) compared with the control group. However, survival of epilepsy surgery patients was lower than that of a matching general population (p < 0.001), with a risk ratio for death of 6.2 (95% CI 3.1-12.6; p < 0.001). In this long-term study of a national cohort of epilepsy surgery patients, we found no beneficial effect of epilepsy surgery on survival compared with a control group of medically treated patients with intractable epilepsy. The mortality after epilepsy surgery was higher than expected in the general population.

Concordance of clinical forms of epilepsy in families with several affected members. Italian League Against Epilepsy Genetic Collaborative Group.

Evidence for genetic heterogeneity in epilepsy is strong. We evaluated the concordance of clinical forms in the same family in a series of families with several cases of idiopathic epilepsy, collected as part of the Study on the Genetics of Epilepsy of the Italian League against Epilepsy (LICE). The studied families had at least three members affected by an idiopathic form of epilepsy in one or more generations. Seventy-four families (with a total of 296 affected members) have been analyzed; two families had cases with benign neonatal familial convulsions (BNFC); in 25% of the remaining families all members were affected by the same clinical form, 13.9% had a prevalent clinical form with only one affected member with a different seizure type, 36.1% had two clinical forms, and 25% had three forms of epilepsy in the same family. There are no clinical differences in the form of epilepsy between the families concordant for one clinical form and families with two or three clinical forms of idiopathic epilepsies. The distribution of the clinical form in the affected relatives in our families showed the higher concordance with the proband in febrile convulsions (FC, 70.8%) and in epilepsy with generalized tonic-clonic seizures (EGTC, 63.0%). FC and EGTC were highly diffused in the affected relatives in the families with other forms of idiopathic epilepsy, above all in the more distantly related affected family members. In our families we observed a rare associated between childhood absence epilepsy (CAE) and juvenile myoclonic epilepsy (JME).(ABSTRACT TRUNCATED AT 250 WORDS)

Depression in temporal lobe epilepsy before epilepsy surgery.

PURPOSE: This study examined the association of depression with laterality of epilepsy surgery in patients with temporal lobe epilepsy before standard lobectomy. METHODS: Forty-nine patients presented for EEG telemetry for localization of epilepsy and eventual temporal lobectomy. Patients underwent routine neuropsychiatric evaluation blinded for epileptic focus, including ratings on depression. Patients were grouped according to right (n = 25, M = 10/F = 15) and left (n = 24, M = 13/F = 11) temporal lobectomy. Analysis of variance included side of surgery as grouping variable and sex, general depressive, cognitive depressive, and vegetative depressive symptoms as dependent variables. Chi2 analyses included categoric variables of sex, handedness, education, neuropathologic findings, and current affective disorders. t Tests were performed on variables of age, epilepsy duration, and cognitive function. RESULTS: Right and left temporal epilepsy groups did not differ with regard to sex, handedness, age, duration of epilepsy, education, cognitive function, and neuropathology. Patients with right temporal epilepsy rated higher on general, cognitive. and vegetative depression scores. Women scored higher on general, cognitive, and vegetative depression scores. Current affective disorders were more common in the right temporal epilepsy group. CONCLUSIONS: Depression ratings and diagnoses were more prominent in patients with right temporal lobe epilepsy and in women in particular. The strength of this laterality finding lies in the selection of patients, as all underwent epilepsy surgery. The finding on gender difference partly reflects the higher incidence of depression in women and needs further exploration. The laterality finding contrasts with recent findings in epilepsy, stroke, and trauma that associate depression with left hemispheric lesions. However, our results are consistent with findings in electrically hyperactive lesions such as gelastic and dacrystic epilepsy.

Direct and indirect costs of refractory epilepsy in a tertiary epilepsy center in Germany.

PURPOSE: There are only few studies on the costs of epilepsy in Germany. Therefore, we performed a pilot study to estimate the direct and indirect costs of refractory epilepsy in a German epilepsy center. METHODS: A "prevalence-based," cross-sectional convenience sample of adults with active epilepsy attending the outpatient clinic of our tertiary epilepsy center was evaluated. Seizure-free patients and patients presenting with their first seizure were excluded. Direct and indirect costs were prospectively recorded over a three-month period using questionnaires and a patient diary. Cost driving factors were identified. RESULTS: One hundred one patients were included (40.7+/-15.2 years; disease duration: 18.1+/-15.3 years; 6 patients had focal epilepsy with simple partial seizures only, 28 with complex partial seizures, 43 with secondarily generalized tonic-clonic seizures; 20 had idiopathic generalized epilepsy with generalized tonic-clonic seizures). The total costs of epilepsy per patient were in average euro 2610+/-4200 over the three-month period. Direct cost contributed 39% to the total costs. Costs of anticonvulsant medication were the main contributor to the direct costs while indirect costs were caused mainly by losses due to early retirement. Cost driving factors included higher seizure frequency, longer disease duration, ictal falls, and situationally inappropriate complex behavior during or after the seizure. CONCLUSIONS: Indirect costs were higher than direct costs in adult patients with active epilepsy attending a German epilepsy center. Medication contributed the most to the direct costs and early retirement was the main factor for the indirect costs. The costs of poorly controlled epilepsy in this German study were above average of the European costs of epilepsy.

The effect of a special nurse on patients' knowledge of epilepsy and their emotional state. Epilepsy Evaluation Care Group.

BACKGROUND: People with epilepsy often report being given insufficient information and support. However, there is little evidence from general practice about how much they know and how they feel. AIM: To describe social differences in the knowledge of epilepsy of people with the condition and test the potential effect of a nurse intervention in general practice on patients' knowledge and depression levels. METHOD: A questionnaire that included measures of knowledge, anxiety, and depression was sent to people with epilepsy aged over 15 years who were registered with 37 general practitioners. Responders were randomized to a controlled trial, offering either two appointments with an epilepsy nurse or usual care. Six months later they were reassessed. RESULTS: Two hundred and fifty-one out of 283 (89%) of the patients with epilepsy completed questionnaires and entered the study at Stage 1. One hundred and ninety-six out of 232 (84%) of those who entered the study, who remained in the practices and were eligible, returned questionnaires at Stage 2. The average duration of epilepsy was 23 years (range 2-79 years). There were significant differences in patients' levels of knowledge of epilepsy at Stage 1. Younger people, those who had left school after 16 years of age, those with GCSEs, and people who belonged to self-help groups had higher knowledge levels, and these were independent effects. Older people and those with a recent epilepsy attack had significantly higher depression scores. Knowledge scores did not differ significantly after the nurse intervention (Stage 2). At Stage 2, the risk of depression was less in the group randomized to be offered nurse input; the effect was mainly in a subgroup of patients with no recent epilepsy attack; their risk of depression was a third of the risk in the control group. CONCLUSIONS: Knowledge of epilepsy differs significantly, with social factors and self-help group membership having independent effects. A nurse-run clinic reduced the risk of depression for people with no recent epilepsy attack, but knowledge levels were not affected. This does not exclude the potential for patients learning more about epilepsy; it may be useful to suggest that patients join self-help groups early on.

Sleep influence on seizures and epilepsy effects on sleep in partial frontal and temporal lobe epilepsies.

OBJECTIVES: A reciprocal effect is observed between sleep and epilepsy. Sleep effect on epilepsy is protective and facilitating. Reciprocally epilepsy alters sleep organization and microarchitecture. This interelationship is well established for some epilepsies but remains undefined for cryptogenic and symptomatic frontal and temporal lobe epilepsies. In order to research sleep influence on seizures and epilepsy effects on sleep we carried out two studies in patients with cryptogenic/symptomatic frontal or temporal lobe epilepsies. METHODS: The occurrence of seizures in relation to the state of alertness was analyzed in patients with (1) mesial temporal and frontal lobe epilepsy, and (2) in patients with mesio-lateral temporal and mesial temporal lobe epilepsy in several conditions. Sleep analysis (organization and microarchitecture) was realized. RESULTS: We found: (1) a precise relationship between sleep and seizures in frontal lobe epilepsy (FLE); (2) a precise relationship between wakefulness and seizures in temporal lobe epilepsy (TLE); (3) sleep organization was normal in FLE and altered in TLE; (4) alterations of sleep microarchitecture in FLE and TLE. CONCLUSIONS: Seizure occurrence was mainly in relation to sleep for FLE and to wakefulness for TLE. Sleep organization appeared more altered for TLE than FLE. These results allow practical applications to localize and study FLE and TLE.
