Study to Understand Novel Biomarkers in Researching Dementia

Washington University School of Medicine

Start Date

8/14/2024

Completion Date

12/1/2028

Summary

The purpose of this study is to determine the relationships between amyloid, tau, and neurodegeneration biomarkers in the blood and the presence of Alzheimer's disease (AD) pathology, clinical cognitive decline, and diagnosis. We aim to understand how well blood-based biomarkers can diagnose and predict Alzheimer's disease, which will help to further develop and validate blood tests for the disease.

Detailed Description

All participants who are eligible and provide informed consent will complete an initial study visit, which includes a research blood collection and cognitive assessments. Depending on the results of the cognitive assessments, participants will complete follow-up visits annually or biennially for additional cognitive testing, research blood collections, and potential clinical testing for Alzheimer's disease as determined by the participant's medical provider.

Eligibility Criteria

Age Range: 60 years to No maximum

Inclusion Criteria: * At least 60 years of age * 80% of the newly enrolled clinic-based cohort will have symptoms of forgetfulness, mild cognitive impairment, mild dementia, or Alzheimer's disease as determined by their medical chart and/or provider * All SEABIRD participants will be invited to participate regardless of their cognitive status Exclusion Criteria: * Unable to perform one or more basic activities of daily living (eating, bathing, dressing, ambulating, toileting) due to cognitive impairment * Uncontrolled hepatitis B, hepatitis C, or HIV at time of blood collection * Taking a disease-modifying drug for AD at time of enrollment * Blood transfusion in the last three months * Unwilling or unable to participate in all study activities
