Blood-based biomarkers are biological molecules — for example, proteins — that can signal disease.

In Alzheimer’s disease, proteins like tau and beta-amyloid build up in the brain. With this course, patients and caregivers will better understand what Alzheimer’s biomarker blood tests do and how doctors interpret the results.

In this guide, you’ll learn about:

• Types of blood-based biomarkers related to Alzheimer’s
• Advances in blood-based dementia diagnosis tools
• How physicians interpret these blood test results
• Who should consider an Alzheimer’s blood test
