Partners


 

GAAIN seeks to establish trusted partnerships with centers that collect and study data from subjects with Alzheimer’s disease, dementia and aging. Given that the Alzheimer’s disease research community is large, diverse, and rich in resources, our goal is to bring together research leaders and maximize the potential for scientific discovery using existing genetic, imaging, clinical, behavioral and other data.

GAAIN’s success depends upon uniting Alzheimer’s disease and dementia study centers that have decided to participate in the partner program and our goal is to develop a strong platform from which investigators can study these Alzheimer’s disease data in a collaborative and innovative manner.
