These data were acquired with the overall goal of determining the regional and longitudinal pattern of changes in the brain which best predict future cognitive decline and dementia due to Alzheimer's disease (AD). The data set includes longitudinal clinical evaluation, cognitive testing, and neuroimaging assessments from a non-demented study population aged 65 and up who complain of memory problems and show some indication of memory and/or executive functioning below age/gender/education adjusted norm.
