Principal Investigator: Marilyn Albert, Ph.D.

The goal of this study is to obtain longitudinal clinical, neuropsychological, neuroimaging and biomarker data from three groups of subjects: (1) elderly normal controls, (2) subjects who meet criteria for mild cognitive impairment (MCI), and (3) patients with mild Alzheimer's disease (AD).

The imaging data consists of both magnetic resonance imaging (MRI) and positron emission tomography (PET) scans. The biomarker data are obtained from both blood and cerebrospinal fluid. Subjects are evaluated every 6 months for 5 years. Approximately 40 sites across the U.S. are participating. The Principal Investigator of the overall study is Dr. Michael Weiner at UCSF. The Principal Investigator of the Johns Hopkins site is Dr. Marilyn Albert.
