The Global Alzheimer’s Association Interactive Network (GAAIN) has developed the first operational online integrated research platform, which links scientists, shared data, and sophisticated analysis tools. Investigators can address scientific questions of unprecedented complexity by accessing massive shared data sets and can share their own data by joining our global network of Alzheimer’s disease study centers. The GAAIN team has recruited data partners and affiliates all over the world to join the effort to accelerate Alzheimer’s disease research. These groups provide resources and data enabling investigators to perform comparative data analysis and cohort discovery. GAAIN, funded by the Alzheimer’s Association, continues to improve and expand while reaching out to new potential data partners, developing and refining a comprehensive, efficient platform where investigators can search, access, and analyze Alzheimer’s disease data (as well as data related to dementia and aging) in a collaborative and innovative manner.
