Abstract submission is now closed. Accepted abstracts must be presented in person at the 2026 Annual Meeting in Chicago.

Disclosures

All abstract authors must have a complete disclosure statement on file by 11:59 p.m. CT on Tuesday, October 21, 2025.

Notifications 

Notification emails will be sent from AAN@mirasmart.com to the first author on the abstract submission at the end of January. Please check your spam or junk folder in case the email is marked as spam by your provider. Contact Katie Anderson if you have not received your notification email by early February. As abstract presenters, first authors will receive an extension code for the Annual Meeting early registration rate.

Accepted abstracts, not including late-breaking science abstracts, will be released to the public on Thursday, March 5, 2026. All authors must adhere to the AAN’s embargo policies. Abstracts accepted to the Annual Meeting can be presented at another conference as long as the abstract has not been selected for AAN press release.

Presentation

Accepted abstracts must be presented in person at the Annual Meeting, and meeting registration is required. An individual can present a maximum of five abstracts, and no more than two abstracts in platform sessions. The AAN's Science Committee makes the final decision of approval, abstract assignment, and presentation type based on scientific merit and program considerations. Authors will be allowed to designate a new presenter after the notification emails are sent out.

Withdrawals 

Withdrawal requests are permitted until April 10, 2026. However, depending on when the request is made, not all withdrawals may be reflected in print or online publications.  

Withdrawal requests should be submitted to Katie Anderson and include the abstract title, ID number, presenter’s name, and reason for withdrawal. Authors not notifying AAN staff of withdrawal, notifying AAN staff after April 10, 2026, or not providing a sufficient reason for withdrawal will be subject to sanctions.

The Late-breaking Science program highlights the most current research being done in the field of neurology. Abstracts qualify for Late-breaking Science by having key aspects of research conducted after the October abstract submission deadline. These abstracts must be new and of sufficient scientific importance to warrant expedited presentation and publication, and contain timely, significant, and innovative content. Case reports are not acceptable submissions and will not be considered.

Late-breaking Science submissions must not have been presented or published elsewhere before the 2026 Annual Meeting. No data or results can be shared at any time before the abstract presentation at the Annual Meeting, should the abstract be accepted. If any part of your data or results will be shared elsewhere, your abstract will be ineligible for the Late-breaking submission period.

Accepted abstracts must be presented in person at the 2026 Annual Meeting in Chicago and will be under embargo until the time of presentation.

Submission fees 

A non-refundable submission fee will be charged for each abstract submission. The fee is based on the first author’s training and member status. 

• AAN members: $175
• Nonmembers: $275
• Interns, junior residents and fellows, PhD candidates, and students (medical or graduate): $0
