Read our Alzheimer's Disease research guide →Researchers are testing a new blood test called the AD-seeds-detector that can find very small amounts of proteins (called Aβ and Tau seeds) linked to Alzheimer's disease. These proteins are believed to be early signs of the disease before symptoms become obvious. The goal is to see if this blood test can accurately tell the difference between people with Alzheimer's, people with other types of dementia, and people with normal memory.
Right now, diagnosing Alzheimer's disease is difficult and often happens after significant brain damage has already occurred. A simple blood test that can catch the disease earlier could help doctors start treatment sooner and help patients plan for their care.

If you join this study, you will have blood drawn so researchers can test it for these early protein markers of Alzheimer's. You will also complete some memory and thinking tests to assess your current cognitive abilities. The study is being done at one location initially, then expanded to multiple hospitals, and researchers will compare results between people with Alzheimer's, other dementias, and those with normal memory to see how accurate the blood test is.
