Join a New Trial Designed to Prevent Alzheimer’s Disease

Join a New Trial Designed to Prevent Alzheimer’s Disease

The A4 study is recruiting older adults ages 65 to 85 with no outward signs of dementia to participate in a landmark prevention trial. 

Physicians and researchers will use an imaging test to determine whether a potential participant has evidence of elevated amyloid plaque buildup in their brains. People with elevated levels will be eligible to participate in the study, which will involve trials of the investigational drug and a placebo, as well as regular thinking and memory tests.

The A4 study, coordinated by the Alzheimer's Disease Cooperative Study, is a public-private partnership funded by the National Institute on Aging, Eli Lilly and Company, and a number of philanthropic organizations.
