About Alzheimer’s Disease Data Initiative
The Alzheimer’s Disease Data Initiative is on a mission to fundamentally transform Alzheimer’s disease and related dementias research. We offer researchers around the world secure data sharing and analytics tools and collaboration resources, all available to users at no cost.
Led by a global coalition of academic, industry, government and nonprofit partners, the Alzheimer’s Disease Data Initiative empowers researchers by fostering research collaboration, enabling seamless access to multiple data sharing platforms, and unlocking important Alzheimer’s disease and related dementias (ADRD) datasets.
Together, we are advancing scientific breakthroughs and accelerating discoveries in new diagnostics, treatments, and cures for ADRD.
Join the Alzheimer’s Trials Data Discovery Challenge
Powered by the AD Data Initiative and Vivli, and supported by Alzheimer’s Research UK
The Alzheimer’s Trials Data Discovery Challenge will award $75,000 in prizes to teams that can unlock discoveries from the new Integrated Alzheimer’s Disease Clinical Trial Dataset – a fully harmonized dataset featuring decades of placebo-arm data from 11 trials, ready for analysis on Vivli’s secure, cloud-based research environments.
The challenge is open now. Submit your Letter of Intent by the first deadline: September 1, 2026.
Advancing discoveries through collaborative effort
Guided by priority research questions that were developed by a coalition of partners and leaders in the AD field, we’re advancing a scientific strategy to seed innovation and accelerate breakthroughs in Alzheimer’s and related dementias research.
Powering research though our interoperable data sharing and analytics environment
340+ Datasets | 10K+ Registered Users | From 129+ Countries
AD Workbench – a secure, cloud-based data sharing and analytics environment – is the interoperability layer of the AD Data Initiative technical suite and its flagship product offering.
Easy to use and available at no cost, AD Workbench empowers researchers around the world to share, access and analyze data across platforms.
For Researchers
Researchers can access a diverse collection of over 100 novel datasets and collaborate, curate, combine, analyze and visualize data via secure, private, cloud-based Workspaces.
For Data Contributors
Data contributors can securely share their ADRD data and manage permissions and access. We offer a variety of tools to help contributors more easily share data to advance ADRD research.
Accelerating research through strategic initiatives and collaborative science
We invest in strategic initiatives such as fellowships, data challenges, and driver projects to foster global collaboration, empower researchers, and advance scientific discovery. Learn about our coalition’s efforts to encourage and enable more data sharing and collaborative science.
Gates Notes
Posted June 2, 2026
We are entering a golden age of Alzheimer's research. Our understanding of the disease is improving rapidly, and I expect to see many breakthroughs in the months and years ahead. I’m particularly excited about how AI’s ability to find meaning in large amounts of data will make research go a lot faster.
