Abstract
Seizures affect the lives of 10% of the global population and result in epilepsy in
1 to 2% of people around the world. Current knowledge about etiology, diagnosis, and
treatments for epilepsy is constantly evolving. As more is learned, appropriate and
updated definitions and classification systems for seizures and epilepsy are of the
utmost importance. Without proper definitions and classification, many individuals
will be improperly diagnosed and incorrectly treated. It is also essential for research
purposes to have proper definitions, so that appropriate populations can be identified
and studied. Imprecise definitions, failure to use accepted terminology, or inappropriate
use of terminology hamper our ability to study and advance the field of epilepsy.
This article begins by discussing the pathophysiology and epidemiology of epilepsy,
and then covers the accepted contemporary definitions and classifications of seizures
and epilepsies.
