Epilepsy: a classification for all seasons?

Epilepsy classification is close to the heart of every clinician because it affects every consultation. Acceptance of change to fundamental concepts is difficult and implementation of new ideas requires considerable effort. It is therefore not surprising that the 2010 Organization of the epilepsies has evoked much passion and its fair share of criticism and controversy. Debate has been positive and has already led to modifications and gradual acceptance of the new framework. Although classification will never be perfect and continues to evolve with increasing knowledge, the time for updating our thinking to reflect current concepts and scientific understanding is well and truly here. Ongoing discussion will help to further mature the new organization.
