The history of the concept of epileptic encephalopathy.

ABSTRACT

The first description of epileptic encephalopathies dates back to Dr. West who, in 1857, described the syndrome that took his name. In addition to West syndrome, in the last century other epileptic syndromes entered into the chapter of epileptic encephalopathies. Henry Gastaut has the virtue of having created the modern concept of epileptic encephalopathy and entering it into the official terminology of the International League Against Epilepsy (ILAE). After the first proposal, it was further defined and refined over time.
