    Abstract Introduction: to investigate the childhood epilepsy incidence, population trends, associated factors, and validate the national population registers.
    Methods: a comprehensive comparative analysis of childhood epilepsy in the population during two distinct time intervals using medical records, appropriate national medical and population registers, and two random samples for control.
    Results: In 1961-1964, the average incidence of epilepsy was 38/100,000 and during 1991-2000 65.9 (95 % CI 59.6 to 72.2) and 65.6/100,000 person-years after adjustment for the European Standard Population. This increase was significant (p<0.0001) as was a decline (p<0.003) from 1991 to 1995 to 1996-2000. The decline in incidence for girls occurred at a younger age compared to boys. Epilepsy cases associated with prenatal and perinatal factors were 50 % lower in 1991-2000 than in 1961-1964, especially related to asphyxia, infections, pre-eclampsia, and imminent abortion. The national Register for Healthcare independently identified 94.5 % of relevant cases (University Hospital alone 81.2 %, and Drug Register alone 74.3 %).
    Discussion: Over the past five decades, the incidence rate of childhood epilepsy has exhibited a dynamic pattern, with a notable increase until the 1990's, followed by a stabilization at an incidence rate of approximately 60-70 per 100,000 person-years. Our findings, in line with other recent Finnish research, support a significant decrease in incidence since the mid-1990's. The underlying reasons for the increase and decrease remain unclear. Finnish national registers for epilepsy have established themselves as highly dependable resources for conducting epidemiological research.
    Conclusion: Childhood epilepsy incidence in Finland is similar to other industrialized countries, but there are signs of a declining trend emerging.

    Abstract Despite an increasing literature, there are many unanswered questions about transition to adult care for youth with chronic disorders. This paper questions the definition and components of optimal transition programs, their effectiveness and costs. Few transition programs have been comprehensively evaluated and effectiveness studies are usually based on a historical control group. Transition clinics for neurological disorders are described but not evaluated. Studies in diabetes, renal transplant, and rheumatologic disorders provide the best available evidence, albeit limited, of the value of transition clinics/programs. A few studies have addressed the cost of transition clinics and suggest that the incremental costs of the clinic are recouped by reduced medical costs in adult care. There is room for a great deal more research about transition.

    Abstract Regression in children with epilepsy may involve loss of cognitive abilities, failure to progress or a slowing of developmental trajectory. A few seizures do not lead to regression. Large numbers of seizures may be associated with regression but the cause is an important cofounder. Individual spike discharges on EEG are associated with transient cognitive impairment and continuous spike discharges with regression. Regression may be global in continuous spike wave in slow sleep (CSWS) or specific (auditory agnosia) in Landau Kleffner syndrome. Regression is mild and transient in Rolandic Epilepsy or profound and permanent in West Syndrome. Epilepsy syndromes grouped under "epileptic encephalopathies" may lead to regression, although proof of this concept is not strong for many syndromes. The absence of cognitive assessment before epilepsy onset, the contribution of the cause and complications of treatment make for difficult methodological problems. The large majority of children with epilepsy do not have regression. There is need for more longitudinal studies of children with epileptic encephalopathies and other epilepsies associated with regression.

    Abstract Cognitive problems ranging from mild specific learning problems to profound intellectual disability (ID) are very common in children with epilepsy. For most affected patients there is good evidence that the cognitive problems are present at the onset of seizures and do not deteriorate over time. There is no evidence that a few seizures lead to cognitive deterioration. An exception may occur in children with epileptic encephalopathies, although this contention is not always easy to prove. ID is a strong predictor of intractable epilepsy, and the greater the degree of the ID the greater the risk of medication resistant epilepsy. It is not known if specific learning disorders are associated with more severe epilepsy. Rolandic epilepsy is unusual because possibly one-third of patients have transient cognitive and behavioral difficulties during the active phase but later have normal adult social outcome. More longitudinal studies with baseline and repeated cognitive assessments are needed to fully understand the relationship of cognitive problems to childhood onset epilepsy.

  8. Article ; Online: Intractable seizures after a lengthy remission in childhood-onset epilepsy.

    Abstract Objectives: To establish the risk of subsequent intractable epilepsy after ≥2, ≥5, and ≥10 years of remission in childhood-onset epilepsy.
    Methods: From the Nova Scotia childhood-onset epilepsy population-based cohort patients with all types of epilepsy were selected with ≥20 years follow-up from seizure onset (incidence cases). Children with childhood absence epilepsy were excluded. The rate of subsequent intractable epilepsy was then studied for patients with ≥5 years remission on or off AED treatment and compared with the rate for those with ≥2 and ≥10 years of remission.
    Results: Three hundred eighty-eight eligible patients had ≥20 years follow-up (average 27.7 ± (standard deviation) 4 years) until they were an average of 34 ± 6.5 years of age. Overall, 297 (77%) had a period of ≥5 years of seizure freedom (average 21.2 ± 8 years), with 90% of these remissions continuing to the end of follow-up. Seizures recurred in 31 (10%) and were intractable in 7 (2%). For the 332 with a remission of ≥2 years seizure-free, 6.9% subsequently developed intractable epilepsy (p = 0.001). For the 260 with ≥10 years remission, 0.78% subsequently developed intractable epilepsy (p = 0.25 compared with ≥5 years remission).
    Significance: Even after ≥5 or ≥10 years of seizure freedom, childhood-onset epilepsy may reappear and be intractable. The risk is fortunately small, but for most patients it is not possible to guarantee a permanent remission.

    Abstract Aim: To (1) summarize published, peer-reviewed literature about the incidence and prevalence of epilepsy in children from developed and developing countries around the world, and (2) discuss problems in defining aetiologies of epilepsy in children, and distinguish between seizures and epilepsy.
    Methods: Review of selected literature with particular attention to systematic reviews.
    Results: The incidence of epilepsy in children ranges from 41-187/100,000. Higher incidence is reported from underdeveloped countries, particularly from rural areas. The incidence is consistently reported to be highest in the first year of life and declines to adult levels by the end of the first decade. The prevalence of epilepsy in children is consistently higher than the incidence and ranges from 3.2-5.5/1,000 in developed countries and 3.6-44/1,000 in underdeveloped countries. Prevalence also seems highest in rural areas. The incidence and prevalence of specific seizure types and epilepsy syndromes is less well documented. In population-based studies, there is a slight, but consistent, predominance of focal seizures compared with generalized seizures. Only about one third of children with epilepsy can be assigned to a specific epilepsy syndrome, as defined by the most recently proposed system for organization of epilepsy syndromes.
    Conclusions: The incidence and prevalence of epilepsy in children appears to be lower in developed countries and highest in rural areas of underdeveloped countries. The reasons for these trends are not well established. Although focal seizures predominate, the incidence and prevalence of specific epilepsy syndromes is not well documented.
