The International League Against Epilepsy (ILAE) is an international organisation focused on epilepsy. Its work brings together regional and national chapters, expert commissions, committees and working groups to advance knowledge, policy and practice related to the condition. The ILAE provides professional resources, including guidance on epilepsy definitions, seizure and syndrome classification, diagnosis and treatment, as well as reports and recommendations developed by its experts.

It supports education through sponsored meetings, courses, summer schools and webinars covering topics such as EEG, neuroimaging, epilepsy surgery and paediatric epilepsy. The organisation also promotes advocacy and policy initiatives, sharing resources on global and regional epilepsy priorities, research sponsorship, and chapter membership. Its publications include the journals Epilepsia, Epilepsia Open and Epileptic Disorders, alongside congress abstracts, reports and podcasts.

Through regional activities, awards, historical archives and collaboration with national chapters, the ILAE connects the epilepsy community and supports international efforts to improve understanding and care. Its website serves as a hub for these resources, programmes and organisational information
