NIH-Supported Study Looks for Earliest Changes in the Brain That May Lead to Alzheimer's Disease
Volunteers are being sought for a clinical study examining the subtle changes that may take place in the brains of older people many years before overt symptoms of Alzheimer's disease appear. Researchers are looking for people with the very earliest complaints of memory problems that affect their daily activities. The study will follow participants over time, using imaging techniques developed to advance research into changes taking place in the structure and function of the living brain, as well as biomarker measures found in blood and cerebrospinal fluid.
The National Institute on Aging (NIA), part of the National Institutes of Health, and the NIH Office of the Director are funding the $24 million, two-year Alzheimer's Disease Neuroimaging Initiative Grand Opportunity (ADNI-GO) study. Researchers seek to recruit 200 volunteers between the ages of 55 and 90 who may be transitioning from normal cognitive aging to an early stage of amnestic mild cognitive impairment (aMCI), a condition that may progress to Alzheimer's disease. Participants may volunteer at 51 sites across the United States.
