Multimodal Query Tool

What is the Multimodal Query Tool?

How to Use the MQT V1

  1. Set your filters to define participant selection criteria.
  2. Run multiple queries as needed (e.g., for case/control groups).
  3. Download NACCIDs for participants who meet your criteria.
  4. Record your filters to create a reproducible selection record for manuscripts (your filters appear in the top right corner of the tool).
  5. Request full datasets through the Quick Access File Data Request System. You’ll need to sign a DUA to access data across multiple modalities.
  6. Use your statistical software to restrict the Quick Access File to your selected participants.
  7. Use your “shopping list” (NACCID list) to streamline access to additional data modalities from partner repositories (e.g., NCRAD, NIAGADS, ADKP, LONI).

About MQT V1 (Prototype)

MQT v1 is a prototype release currently undergoing validation and continued development. Minor discrepancies may exist between searchable data in MQT and the March 2025 Quick Access File (QAF). These will be resolved when the QAF is migrated to the new NACC Data Platform in Q4 2025. Questions? Contact us at nacchelp@uw.edu.

What's Next?

We’re actively developing new functionality for the MQT, with a major update planned for late Q3 2025.
