    The National Alzheimer’s Coordinating Center (NACC) functions as the centralized data repository, and collaboration and communication hub for the National Institute of Aging’s (NIA’s) Alzheimer’s Disease Research Centers (ADRC) Program, which currently includes 35 centers across the United States.
    NACC is home to one of the largest, oldest, and most powerful Alzheimer’s datasets, built in collaboration with more than 42 Alzheimer’s Disease Research Centers (ADRCs) throughout the US over the past 20+ years.
