The Epidemiology of Epilepsy in Rochester, Minnesota, 1935 Through 1967

Abstract
SUMMARY: Other demographic studies of epilepsy have revealed mean annual incidence rates ranging from 17/100,000 (Sato, 1964) to 70/100,000 (Pond et al., 1960) and prevalence rates from 2.8/S, OOO to as high as 15/1,000. Comprehensive review of their methods indicates that, although rates may indeed differ among different populations, a major problem is the wide variation in the completeness of case ascertainment and the definitions of epilepsy used.
