To establish the prevalence rate (PR) and main characteristics of childhood epilepsy in Estonia.
We performed a population-based case ascertainment of all the possible sources of medical care in seven counties of Estonia from January 1995 to December 1997.
Only cases of patients from I month to 19 years of age with active epilepsy (i.e., at least one seizure during the last 5 years, regardless of treatment) were included.
All patients were examined by a pediatric neurologist.
Five hundred sixty cases met the study criteria on the prevalence day, December 31,1997.
The total PR was 3.6 per 1,000 population (boy/girl ratio, 1.2 : 1.0).
The PR was the highest-4.3 per 1,000-in the 5-to-9-year-old age group.
The prevalence declined markedly in children age 14 years and on.
The correlation between age and PR was negative (-0.542, p<0.0001) by regression analyses.
The most frequent seizure types in the total group were primarily generalized seizures-PR 2.1/1,000 [rate ratio (RR) 1.4,95% confidence interval (CI) 1.2,1.6]. The predominance of generalized seizures was significant in those younger than 10 years.
In 14.8% of cases, there was a history of epilepsy among first-and second-degree relatives.
Benign rolandic epilepsy-PR 0.2/1,000-was the most frequent among idiopathic syndromes, and Lennox-Gastaut syndrome-PR 0.08/1,000-was the most frequent among cryptogenic ones. (...)
