Participants are invited to participate in a longitudinal study of brain changes in older adults. Participants include both male or female subjects from the ages of 55 to 90 years who are willing to participate in tests including brain imaging, blood sampling, spinal fluid testing, and memory testing over a four and a half year follow-up period. Qualified participants include four groups: healthy older adults with no memory problems, persons with mild memory problems, persons with moderate memory problems, and those with early Alzheimer’s disease. The study is conducted in cooperation with the Alzheimer’s Disease Neuroimaging Initiative supported by the National Institute of Health and the Alzheimer’s Association.
Participation is voluntary and compensation is provided.
