Epilepsy Diagnosis Logo

The ILAE welcomes you to, a cutting edge online diagnostic manual of the epilepsies.


The goal of is to make available, in an easy to understand form, latest concepts relating to seizures and the epilepsies. The principle goal is to assist clinicians who look after people with epilepsy anywhere in the world to diagnose seizure type(s), epilepsy type, diagnose epilepsy syndromes and define the etiology of the epilepsy. The site is principally designed for clinicians in primary and secondary care settings caring for people with epilepsy and we hope will also serve as a useful teaching aid.


The structure of this site reflects the importance of seizure type, epilepsy type, syndrome, and etiology in clinical practice. On this website, you will find current classification concepts for seizures, with their clinical features, video examples, EEG correlate, differential diagnosis and related epilepsy type, epilepsy syndrome and etiology. Epilepsy syndromes are detailed by their clinical features, seizure types, EEG, imaging and genetic correlates and differential diagnoses. The site includes sections on etiologies of epilepsies and epilepsy imitators with cross-referencing between these sections and seizure and syndrome sections.


A short and instantaneous registration process is required to view videos on this site, and this is open to anyone, anywhere in the world with an internet connection. Individuals with seizures or epilepsy imitating conditions and their families have kindly given consent for videos to be freely available in this way.

Further development

You will notice that there are some sections that do not have video examples as yet, notably Epilepsy Imitators, and some text sections that require expansion. The ILAE will continue to develop and add further videos and text over time.

Please have a look, use it for your own education, for teaching and let colleagues, patients and families know about the resources on this site. We would be very grateful if you could complete the survey on the Give Feedback page. This will help us in our further development of this continually evolving site.
