Abstracts
Following the success of the 36th International Epilepsy Congress in Lisbon, with over 4400 participants from 120 countries, you can now catch up on all presented abstracts at the congress in Epilepsia.
More than 1100 abstracts were presented through both platform and poster sessions. Poster presentations were available across the full three days of the Congress—an approach that continued to encourage vibrant discussions, knowledge exchange, and international networking among delegates. The latest multidisciplinary research presented at the platform sessions will help shape the future of epilepsy care.

ABSTRACTS - GENERAL QUERIES
Which reference number should I use when I send a query to the Secretariat?
The personal ID Reference Number that you received when you submitted your abstract should be mentioned in all correspondence.
I am not the first author; may I present the poster on behalf of my colleagues?
Presentation by a second author may be allowed. Once your registration has been completed, please contact abstracts@epilepsycongress.org. Please note however that each author is permitted to present only once during the congress (not including invited lectures).
I am an invited speaker in the congress programme; do I need to submit an abstract?
Invited speakers are not required to submit abstracts to illustrate their talks.
I have been selected for a platform session, but I would have preferred a poster presentation, what can I do?
During the abstract submission process, you were asked if you would prefer poster or oral (platform) presentation, or if you do not have a preference.
The Abstract Review Committee (ARC) took this preference into account and did not select an abstract for platform presentation if the submitter indicated that s/he does not want a platform presentation.
However, if you indicated that you had no preference between poster and platform presentation, then the ARC has selected your work to be presented in a platform session because they felt that it was of high quality and that a large audience would be interested in knowing more about the study. It would be a shame not to use this opportunity to present your work!
However, if you are unable to make an oral presentation, please contact the secretariat at abstracts@epilepsycongress.org for alternative arrangements.
I have been selected for a platform session, what are the guidelines for my presentation?
Please see the “Platform” tab for more information.
