The purpose of the study is to establish a Clinical Cohort (group) of research participants to examine normal cognition, mild cognitive impairment and Alzheimer's disease and related disorders (ADRD) as people get older. We will be measuring changes in your memory and the way you process information as you age. As part of the study, you will be asked to participate in yearly evaluations of your memory and health. You will have brain imagining done by Magnetic Resonance Imaging (MRI), a lumbar puncture and blood will be drawn at some visits. Also, as part of this research you must designate a "project partner." This should be someone who is familiar with your health and will be able to provide information about your health and wellbeing as appropriate.
