## Summary

The Consortium for Biomedical Research and AI in Neurodegeneration (C-BRAIN), led by Dr. Randall Bateman, is partnering with NVIDIA to accelerate Alzheimer's disease research. The consortium, which includes 18 member institutions, launched in November 2025 to address the bottleneck of excessive data and limited expert synthesis. With 57 million people worldwide living with dementia and over 10 million new cases diagnosed annually, the group aims to use AI to process "dark data"—unpublished or proprietary findings that are typically inaccessible to standard models.

To protect patient privacy and institutional governance, C-BRAIN employs a hybrid centralized and federated approach, allowing AI models to learn from data without it leaving its original institution. The infrastructure currently runs on 64 NVIDIA data center GPUs on-premises and cloud-based nodes on Microsoft Azure, with plans to expand using NVIDIA Blackwell systems. The collaboration incorporates the NVIDIA BioNeMo platform and the MONAI framework to build research pipelines.

C-BRAIN has developed two open-source tools: OpenScientist, an agentic AI co-scientist that generates hypotheses and runs analyses, and InsightEngine, which tests hypotheses against scientific literature to catch hallucinations. In case studies, OpenScientist completed analyses in minutes that scientists estimated would take weeks or months, costing under $10 per run. The consortium aims to build a multimodal biological foundation model by year three to discover new causal mechanisms of brain aging.

## Key points

- C-BRAIN partners with NVIDIA to use AI on 64 GPUs for Alzheimer's research.
- OpenScientist tool cuts analysis time from weeks to minutes at under $10 per run.
- Consortium uses federated learning to access private "dark data" without moving it.

## Why it matters

This collaboration addresses a critical gap in neurodegenerative research by making previously inaccessible data usable for AI, potentially accelerating the discovery of treatments for a disease affecting 57 million people.
