InTBIR General Assembly 2024

The International Initiative for Traumatic Brain Injury Research (InTBIR) 2024 General Assembly will be held in Bethesda, Maryland January 24 – 25, 2024. This meeting will take place immediately after the NINDS-sponsored TBI Reclassification Workshop, held in Bethesda from January 22 – 23, 2024.   

All InTBIR members are welcome to attend at their own cost, but total numbers will be capped due to meeting facilities available, so if you do plan to attend in person, we suggest you apply early.  However, this will be a hybrid meeting, so you will also be able to participate online. 

We encourage submission of abstracts describing your research that fits with the InTBIR Mission (, Abstracts will be graded for selection by the InTBIR Executive Committee, and selected abstracts will be expected to be displayed as posters for discussion during breaks.  In addition, five posters will be selected for 3-minute flash presentations.


This meeting has been made possible through support from the US National Institutes of Health, with additional support from the following industry partners. InTBIR is very grateful for this support – which enables us to plan for the future of research in TBI.
