Study to Evaluate Amyloid in Blood and Imaging Related to Dementia (SEABIRD)


This study will evaluate a blood test for detecting amyloid-beta, a protein involved in Alzheimer's disease, in older adults. Researchers are recruiting people with and without memory problems.

Amyloid-beta is a protein that builds up abnormally in the brains of people with Alzheimer's disease. Researchers are investigating the ability of a blood test to detect this protein in order to screen people for the early signs of the disease. Participants will undergo blood collection and cognitive testing, and may be asked to undergo positron emission tomography and magnetic resonance imaging.
