Epidemiology of epilepsy in adults: implementing the ILAE classification and terminology into population-based epidemiologic studies.

The new proposal for Revised Terminology for Organization of Seizures and Epilepsies published in 2010 poses challenges to all fields of epilepsy including epidemiology. We describe efforts to incorporate the new terminology and classification into population-based health registers in Denmark in order to provide the background for assessment of the quality of epilepsy care, epidemiologic studies of epilepsy, and clinical trials in adults.
