Few studies have been carried out in the same area at different times, allowing an assessment of the incidence of epilepsy (E.), including all ages, over time. The available data on temporal trend show a decrease in E. incidence in childhood and an increase in the elderly. We sought to update the incidence of E. in the province of Ferrara, where a previous study estimated an incidence rate of 33.1 per 100,000, 35.8, if standardized to the European population. Newly diagnosed patients aged up to 14 years were drawn from a community-based prospective multi-source registry, and adult onset E. cases were collected through multiple overlapping sources of case collection. Cases were included and classified according to ILAE recommendations. During the study period (2007–2008), 141 newly diagnosed cases (66 men and 75 women) living in the study area were identified. The crude incidence rate was 46.1 per 100,000 person-years (95 % CI 39.0–54.5), 35.5 (95 % CI 28.0–43.0) if adjusted to the European population. The incidence of childhood and adolescence epilepsy was 57.0 per 100,000 person-years (95 % CI 33.8–90.0), lower than that reported in our previous study, and it was 44.8 (95 % CI 37.4–53.6) for adult onset E., which is significantly higher as compared to our previous study. The overall incidence of E. in northern Italy is stable over time. We detected a significant decrease in incidence of childhood and adolescence E. and an increase in adult-onset E. The burden of epilepsy will increase as the population continues to age.
